A button 31 is integrally formed on the side of the movable plate 29 away from the slider 25. Through holes 32 for the corresponding buttons 31 to pass through are respectively provided at the front and rear ends of the adjustment plate 13.

[0037] The button 31 is pressed to drive the slider 25 to move inward along the sliding cavity 24 and compress the spring 28. At the same time, the slider 25 drives the plug plate 26 to disengage from the slot 27. Then, the adjustment plate 13 can be slid to adjust the distance between the two installation slots 33 opposite to each other on the left and right. After the two installation slots 33 are adjusted to a suitable distance, the button 31 is released. The spring 28 stretches and pushes the slider 25 to move toward the side close to the corresponding guide rod 14. At the same time, the slider 25 drives the plug plate 26 to be inserted into the aligned slot 27 at this time, thereby limiting the adjustment plate 13 from sliding left and right along the guide rod 14, making it more convenient to adjust the adjustment plate 13.
