According to the above technical solutions, the handheld cutting tool where the cap (183) and the oil injection port (182) mate with relatively good stability can be provided.

A walk-behind power tool includes: a body supported by a traveling assembly; a handle device, where the handle device is connected to the body and includes gripping handles for a user to hold, and at least part of the gripping handles are configured to be movable relative to the body; a sensing device configured to sense the amount of movement of the at least part of the gripping handles; and a control device connected to the sensing device. The control device is configured to control, according to the amount of movement, the walk-behind power tool to steer. The provided walk-behind power tool can be freely controlled to turn, which is flexible to operate and is safe, convenient, and comfortable to use.

The present disclosure provides a feed and discharge cartridge and a cold beverage maker, where the feed and discharge cartridge includes a cartridge body and a discharge assembly provided on the cartridge body; the cartridge body further includes a guide portion; the guide portion is provided at an end of the cartridge body close to the discharge assembly; the guide portion inclines gradually from an upper portion of the cartridge body to the discharge assembly; an inner wall of the guide portion forms a concave surface; and the inner wall of the guide portion is a concave continuous surface. The present disclosure can facilitate backflow of the formed cold beverage, and can be applicable to smoothie products and ice cream products.

The present disclosure provides a cold beverage maker and a control method thereof. The cold beverage maker includes a body, and a refrigeration mechanism, a stirring mechanism, a feed and discharge mechanism, and a main control apparatus that are provided on the body, where the feed and discharge mechanism includes a making cartridge, a discharge mechanism provided on one end of the making cartridge, and a temperature sensor provided in the making cartridge; the stirring mechanism includes a variable-speed motor apparatus and a stirring member; the variable-speed motor apparatus is connected to the stirring member in a transmission manner; the stirring member is provided in the making cartridge; and the main control apparatus is electrically connected to the refrigeration mechanism, the temperature sensor, and the variable-speed motor apparatus. The present disclosure can make a variety of cold beverage products with a good mouthfeel, achieving multiple uses in one machine.

Provided is a cutting tool. The cutting tool includes a bevel adjustment mechanism (140). The bevel adjustment mechanism (140) further includes an operating member (1411) connected to or formed with a limiting member (1413). Driven by the operating member (1411), the limiting member (1413) has at least a first state, a second state, and a third state. A bracket plate (142) includes a stop portion (1421) capable of being adapted to the limiting member (1413) in the first state or the second state to limit a first limit angle and a second limit angle of the sawing assembly (120) relative to the base (110). When the limiting member (1413) is in the third state, the bevel adjustment mechanism (140) limits the maximum lateral bevel angle of the sawing assembly (120) relative to the base (110) to a third limit angle. The first limit angle is less than the second limit angle.

An inflator includes a motor, a power mechanism, at least one air vent, and a main housing. The power mechanism is driven by the motor and configured to generate airflow. The air vent is connected to a flexible duct for air intake and/or air discharge to allow the airflow to flow. The main housing accommodates the motor and the power mechanism and has a battery coupling portion, where a battery pack that provides a power supply for the motor is capable of being detached from or mounted to the battery coupling portion. The main housing further has a first coupling portion configured to detachably connect an illumination device. The illumination device is capable of illuminating a working region of the inflator.

A fastener driver includes a striking assembly including a striking member configured to strike a fastener; a drive assembly configured to drive the striking member; and an electric motor providing a driving force for at least the drive assembly. The drive assembly includes a drive wheel configured to engage with the striking member to drive the striking member to move along the extension direction of the striking member. The distance D from the centroid of the drive wheel to the rotation axis of the drive wheel is less than or equal to 1.5 mm. In this manner, the regular wobbles of the fastener driver can be reduced, thereby improving the user's operating feel.

A clamping device includes a shaft body including an axial opening and at least one hole, where the axial opening extends along a first straight line; at least one retainer, where each of the at least one retainer is configured to move within a respective hole of the at least one hole; a sleeve sleeved on the outer circumference of the shaft body and configured to move axially relative to the shaft body; an abutting member abutting against the rear side of the at least one retainer; a first elastic member located on the front side of the at least one retainer; and a second elastic member located on the rear side of the at least one retainer and being in contact with the abutting member. The sleeve includes a protrusion extending along a second straight line, and the protrusion abuts against the shaft body, where the second straight line intersects with the first straight line. Along the direction of the first straight line, the protrusion is located at the front end of the at least one retainer and is not in contact with the at least one retainer.

A portable circular saw for cutting metal includes a base including a lower surface side abutting against a cut material and a cutter body at least partially supported on the upper surface side of the base. The cutter body includes a circular saw blade, a fixed shield covering the outer circumferential side of the circular saw blade, and a metal chip guide tube disposed in the fixed shield, surrounding part of the outer circumferential side of the circular saw blade, and including a chip guide cavity for guiding a chip. The ratio of the outer surface area S1 of the metal chip guide tube to a surface area S2 of the metal chip guide tube covered by the fixed shield is higher than 1.

A charger includes: a housing; a charging interface configured to be electrically connected to a first battery pack; a direct current power interface configured to be electrically connected to a second battery pack; and a drive assembly accommodated in the housing and configured to supply power to the charging interface. The drive assembly is electrically connected to the charging interface and the direct current power interface and is configured to transfer electric energy from the second battery pack to the first battery pack, the maximum output power of the drive assembly is greater than or equal to 2000 W, and the first battery pack and the second battery pack are detachably connected to the charger, so as to be detached and then mounted to a power tool and supply power to the power tool.
