The present disclosure provides a rechargeable multifunctional controller for an LED light string comprising a battery and a circuit board arranged inside a hollow shell (1). The battery is set as a rechargeable lithium battery, and power is supplied for the battery through a charging port (4) arranged at one end of a control device.

A support leg stand with support legs (2) capable of fully bouncing off, comprising: a center column (1) with a connecting seat (5); support legs (2), wherein one end of the support leg (2) is rotatably connected with the connecting seat (5), and the other end thereof is a free end; when the free end of the support leg (2) is close to the center column (1), the support leg (2) is folded, and when the free end of the support leg (2) is away from the center column (1), the support leg (2) is unfolded; a locking assembly (3) adapted to fit with the free end of the support leg (2) when the support leg (2) is folded, and the locking assembly (3) will release constraint after being triggered; reinforcing ribs (4), wherein one end of the reinforcing rib (4) is rotatably connected with the support leg (2), and the other end thereof is rotatably connected with the center column (1) or the locking assembly (3); a first elastic member (42) is arranged between the reinforcing rib (4) and the support leg (2); when the locking assembly (3) releases constraint, the free end of the support leg (2) moves away from the center column (1) under action of a restoring force generated by the first elastic member (42) and the support legs (2) fully unfold.

A one-step precipitation and color development detection method of a nitrocellulose (NC) membrane for micro/nano plastics was provided, including the following steps: S1, preparing a micro/nano plastic-ovalbumin (OVA) conjugate; S2, preparing an NC membrane coated with the micro/nano plastic-OVA conjugate; S3, putting the NC membrane coated with the micro/nano plastic-OVA conjugate into a polystyrene antibody solution and a sample solution and incubating for 1 h at 37°C, and then rinsing the NC membrane; S4, diluting goat anti-mouse IgG-horseradish peroxidase (HRP) by 1w fold and then putting in a centrifuge tube, putting the NC membrane into the centrifuge tube, and then incubating for 30 min at 37°C; and S5, washing the NC membrane 4-5 times, completely immersing the NC membrane into a precipitating tetramethylbenzidine (TMB) for 30 s and then taking out the NC membrane at room temperature for development, followed by detecting the concentration of micro/nano plastics.

A telescopic ladder includes a ladder body, and the ladder body includes a plurality of layers of left ladder tubes and right ladder tubes sleeved with each other. The upper left ladder tube and the upper right ladder tube are sequentially sleeved in the lower left ladder tube and the lower right ladder tube respectively, each layer of the left ladder tube and the right ladder tube is provided with a crossbar pedal, and both ends of the crossbar pedal on each layer are connected to the left ladder tube and the right ladder tube on each layer. The telescopic ladder has a simple structure, and when the telescopic ladder is pulled open, the user clearly observes the stability of internal snap-fitted engagement.

The present disclosure discloses a processing process of a toilet lid containing coconut shells and wood flour, aiming to provide a processing process of a high-toughness high-resistance toilet lid formed by combination of coconut shells, wood flour, glass fibers or carbon fibers, a water-proofing agent and urea formaldehyde glue, through multiple screening and grinding and through addition of combined fiber materials. The key of the technical solution is that the coconut shells, the wood flour, the glass fibers or carbon fibers, the water-proofing agent and the urea formaldehyde glue are used, wherein the use of the coconut shells is intended to increase the rational utilization of resources, and the coconut shells are degradable materials. Furthermore, the addition of the fiber materials allows a mixed slurry formed by the coconut shells and the wood flour to have a binding strength brought by the fiber materials.
