[0021] See Figure 6 and Figure 7As shown, the hook and pin device 4 includes a hook and pin slider 41, a fixed guide shaft 44, and a sliding guide shaft 42 located inside the mounting body 2; a track groove 43 is provided in the middle of the hook and pin slider 41; the fixed guide shaft 44 passes through the track groove 43, and both ends of the fixed guide shaft 44 are respectively fixedly installed in the corresponding positioning holes 22; specifically, a hook arm 45 is provided at the upper end of the hook and pin slider 41, and the upper end of the hook arm 45 is bent to form a hook part 46; the hook arm 45 extends into the pin housing 33 and the hook part 46 extends out from the opening groove 34. The opening groove 34 extends laterally through the pin housing 33.
[0022] The piston rod of cylinder 1 extends into the mounting body 2 and is hinged to the lower end of the hook slider 41 via a sliding guide shaft 42; both ends of the sliding guide shaft 42 are slidably disposed in corresponding guide grooves 21. Specifically, the piston rod end of cylinder 1 is provided with a U-shaped connector 11 for mounting the sliding guide shaft 42.
[0023] See Figure 6 and Figure 8 As shown, the positioning pin device 3 includes a support block 31 and a hollow pin housing 33. The support block 31 is cylindrical, and its lower end is bent outward to form a flange edge 32 for connection with the mounting body 2. The pin housing 33 is inserted into the support block 31, and its lower end extends out of the support block 31 and is bent outward to form a limiting flange portion 35.

[0024] The working principle of this utility model is as follows: The cylinder is mounted on the mounting body. When the cylinder extends, the sliding guide shaft slides linearly along the guide groove on the mounting body, thereby driving the hook slider to move linearly. The position of the fixed guide shaft does not change, and the hook slider moves along its own trajectory groove. The motion trajectory can be freely designed according to design requirements. Because of the linear guide shaft, there will be no cylinder jamming during the movement, thus ensuring reliable and stable movement.
