The roller 10 can slide with the sliding block 9 in the bracket guide groove 7, thereby realizing the sliding of the push-pull device access rack 2 relative to the push-pull device bracket 1.

[0045] A push-pull device clamping groove 5 and a push-pull device pressing plate 6 are arranged on the top of the mounting plate 3; in the embodiment, the push-pull device clamping groove 5 is arranged in two parallel grooves in the length direction of the mounting plate 3.

[0046] The push-pull device pressing plate 6 is rotatably arranged at one end of the push-pull device clamping groove 5 and is arranged close to the push-pull bracket panel 4. Specifically, one end of the push-pull device pressing plate 6 is rotatably connected with the mounting plate 3 through a pin shaft 19, the other end is provided with a second spring screw 20 for pressing the push-pull device 23, and a screw hole 21 corresponding to the second spring screw 20 and a shaft counterbore 22 corresponding to the pin shaft 19 are arranged on the mounting plate 3.

[0047] In the embodiment, the push-pull device pressing plate 6 is arranged in an overall “L” shape. When the push-pull device 23 is installed in the push-pull device clamping groove 5, the push-pull device pressing plate 6 is rotated and pressed on the push-pull device 23, and the push-pull device 23 is pressed tightly through the cooperation of the second spring screw 20 and the screw hole 21. In other embodiments, the structure and appearance of the push-pull device pressing plate 6 are designed according to the functional needs, installation space and movement trajectory.

[0048] The pin shaft 19 is made of a stainless steel rod, and the pin shaft 19 is arranged in the shaft counterbore 22 through the push-pull device pressing plate 6.
