A battery (2) adapted to be inserted into a power tool (1), characterised in that it is provided with a locking mechanism (20) comprising: a first guide (211) located in the battery housing upper part (21); a button (22) movably seated in the battery housing (2), comprising a second guide (221) and a ramp (222); a locking rod (23) and a spring (24). In the fixed position, when the battery (2) is inserted into the power tool (1), and when the button (22) is released, the position of the locking rod (23) becomes fixed and permanent due to the pressure of the spring (24), and, by engaging the protrusion (111), the locking rod (23) locks the battery (2) in the power tool (1), preventing its removal. On the other hand, once the button (22) is pressed, the locking rod (23) moves along the first guide (211) and, at the same time, moves along the second guide (221), and ceases to engage the protrusion (111) of the power tool foot (11), thus allowing the battery (2) to be unlocked and removed from the power tool (1).

The object of the invention is an applicator (1) for attaching to a pressure container (20) containing a composition for forming a sealing paste, polyurethane foam, adhesive or another composition, comprising a body (2) adapted for being connected to a pressure container (20) equipped with a valve (21), wherein the body comprises a gripping surface (4) for contacting the user's hand, and the said applicator (1) contains a movable part (5) located in the body (2), adapted for coupling with the valve (21) of the pressure container (20) and for pushing the stem of the valve (21) into the interior of the pressure container (20) to open the valve (21) of the pressure container (20), wherein the movable part (5) comprises a first contact surface (6) for at least one finger of the same hand of the user, located substantially opposite the gripping surface (4) of the body (2). The application characterised in that the movable part (5) is a rotational and tiltable element mounted in the body (2), which comprises a second contact surface (7) for at least one finger of the same hand of the user, preferably the thumb, wherein the second contact surface (7) is located at the opposite end of the movable part (5) relative to the first contact surface (6) for at least one finger of the same hand of the user and is inclined relative to the gripping surface (4) of the body (2) at an angle ranging from 45°, to 135°,, wherein the applicator (1) is configured such that rotational movement of the movable part (5), caused by the user pressing on the first contact surface (6) and/or the second contact surface (7), pushes the stem of the valve (21) into the interior of the pressure container (20), causing the valve (21) of the pressure container (20) to open to dispense the composition from the pressure container (20).

The object of the invention is an apparatus for cutting lay-flat book blocks. Lay-flat books are composed of signatures in a form of single-folded sheets that form adjacent pages. The single-folded sheets form four-page signatures, which are glued together with the entire faces of the sheets, and the sum of the spines of the signatures forms the spine of the book. The apparatus for cutting lay-flat book blocks comprises a cutting unit (3) with a circular saw (4), and is characterised in that the cutting unit (3) comprises at least one longitudinal guide (5) and at least one saw assembly (6). The single saw assembly (6) has a driven slider (7) slidably mounted on a longitudinal guide (5), which is adapted to a reciprocating movement along this longitudinal guide (5) and has the loading grippers (8), the circular saw (4), the unloading grippers (9) fixed in sequence. The longitudinal guide (5) has an attached support table (14) containing a slot for the circular saw (4) and adapted to support the book blocks (1) being cut. The loading grippers (8) and the unloading grippers (9) are fixed vertically in a direction perpendicular to the plane of the support table (14).
