The connecting rod 14 mainly plays a connecting and supporting role between the two support plates, and the connecting plate 13 is arranged close to the upper surface of the two support plates and mainly plays a connecting and supporting role in the gap between the two support plates.

[0029] The locking member 7 includes a spring 72 and an L-shaped block 71. A movable groove 123 connected to the side of the second through hole 120 is downwardly opened on the top surface of the second support plate 12 on both sides of the connecting plate 13, and the block 71 is horizontally slid and clamped in the movable groove 123; the two side edges of the connecting plate 13 are provided with clamping holes 131 at equal intervals along its length direction, the end of the horizontal part of the block 71 is clamped in the corresponding clamping hole 131, and the other end is abutted against the side wall of the movable groove 123 through the spring 72; the vertical part of the block 71 is vertically arranged upward in the movable groove 123 and the length of the vertical part does not exceed the depth of the movable groove 123, so as to prevent the block 71 from extending out of the movable groove 123 and hindering people. By moving the vertical portion of the block 71 in the movable groove 123 outward and compressing the spring 72, the end of the horizontal portion of the block 71 is disengaged from the hole 131 on the connecting plate 13, thereby adjusting the length of the connecting plate 13 between the two support plates. After the adjustment is completed, the block 71 is released and, under the action of the spring 72, the block 71 is re-engaged in the hole 131 of the connecting plate 13, thereby locking the connecting plate 13 and improving the stability of the device.
