[0035] A plurality of second vertical rods 6 are arranged at intervals on the cross rod 5, and the second vertical rods 6 are connected to the driving rod 40 for vertical sliding. The second vertical rods 6 are hollow structures, and second fixed columns 7 are slidably arranged inside the second vertical rods 6. The top ends of the plurality of second fixed columns 7 are connected to the horizontal rod 4.

[0036] In this technical solution, the first upright pole 2 is vertically arranged, the diameter of the first upright pole 2 is larger than the diameter of the second upright pole 6, the cross bar 5 is horizontally arranged, the top end of the first upright pole 2 is open, the first spring 24 is vertically arranged, the second fixed plate 23 is horizontally arranged, the horizontal bar 4 is horizontally arranged, the notches of the two accommodating grooves 20 are arranged opposite to each other and the two accommodating grooves 20 are symmetrically arranged along the central axis of the first upright pole 2, the stopper 22 moves in the horizontal direction, the fourth spring 21 is retracted in the horizontal direction, the lower end of the inclined surface of the stopper 22 is close to the central axis of the first upright pole 2, and the push rod 19 slides up and down along the inner wall of the first upright pole 2 (specifically: two first slide rails are vertically arranged on the first upright pole 2, and a first slider is arranged on the first slide rail, and the two push rods 19 are connected to the two sliders one by one); in the same first upright pole 2, the distance between the two push rods 19 is larger than the diameter of the second fixed block so that the second fixed plate 23 can pass through between the two push rods 19, and the push rod 19 is located When in the highest position, the lower surfaces of the two blocks 22 contact the upper surface of the second fixing plate 23 to fix the second fixing plate 23. When the push rod 19 moves to the lowest position, the shortest distance between the two blocks 22 is greater than the diameter of the second fixing plate 23 (the second fixing plate 23 is circular) so that the second fixing plate 23 can pass through between the two blocks 22; the surface of the horizontal rod 4 is smooth; two second slide rails are provided in the accommodating groove, and two second sliders are provided on the second slide rails.

When an external force presses the driving rod 40, the driving rod 40 drives the push rod 19 to move downward. During the downward movement of the push rod 19, the block 22 moves toward the bottom of the accommodating groove 20. When the push rod 19 moves to the lowest position, the block 22 is separated from the second fixing plate 23.
