[0053] Specific usage and working principle:

[0054] When installing the load-bearing member 20, firstly, align the first guide sliding structure 12 (gourd hole) on the load-bearing member 20 with the first guide sliding structure 12 (I-shaped nail) on the load-bearing tray 10 and install it on the load-bearing tray 10, and then push the load-bearing member 20 into the small hole direction of the gourd hole. When the second inclined surface 2211 on the first telescopic knob 22 touches the first inclined surface on the load-bearing tray 10, under the interaction between the second inclined surface 2211 and the first inclined surface, the first telescopic rod 221 on the first telescopic knob 22 moves upward. When the load-bearing member 20 is installed in place, the first telescopic rod 221 on the first telescopic knob 22 extends out under the action of gravity and is stuck in the first limiting hole 131 on the load-bearing tray 10. The load-bearing member 20 will be fixed in the left and right directions and the up and down directions by the first guide sliding structures 12 on the four corners of the load-bearing tray 10. The first telescopic rod 221 on the first telescopic knob 22 and the first limiting hole 131 on the load-bearing tray 10 The hole 131 cooperates to fix the front-to-back direction, so the carrier 20 will be firmly fixed on the carrier tray 10, and then the assembled tool-free disassembly module 2 is installed in the module fixing frame 1. The steps are to open the handle structure 30 on the tool-free disassembly module 2, align the guide slide rail 104 on the limiting beam 103 of the module fixing frame 1 and install it into the first pull-out hole 102. After it is installed in place, rotate the handle structure 30. After it is rotated in place, the limiting protrusion 33 at the other end of the handle structure 30 is It will be stuck in the clamping hole 101 of the module fixing frame 1, and finally press and rotate the second telescopic knob 32 clockwise, the square mushroom head of the second telescopic rod 321 will extend into the limiting boss 17 at the locking hole 15 and form a cross shape with the limiting boss 17, and then let go, the square mushroom head of the second telescopic rod 321 will be stuck in the step at the limiting boss 17 at the locking hole 15 and cannot rotate. From then on, the tool-free disassembly module 2 is firmly fixed in the module fixing frame 1.

[0055] When the supporting member 20 needs to fail, the module fixing frame 1 is pulled out of the second drawing hole 3021 of the chassis body 3, and then the second telescopic knob 32 is pressed and rotated counterclockwise, the square mushroom head of the second telescopic rod 321 will extend out and form a straight line parallel to the limiting boss 17 at the locking hole 15, and then the hand is released, the square mushroom head of the second telescopic rod 321 will shrink into the second telescopic knob 32, and the handle structure 30 will automatically open under the action of the torsion spring structure 40, and then the tool-free disassembly module 2 is pulled out of the module fixing frame 1, and the tool-free disassembly module 2 is removed from the module fixing frame 1. When the supporting member 20 moves, the first telescopic knob 22 is rotated clockwise, and the first limiting spiral groove 2231 on the first telescopic knob 22 will squeeze the first pin 224 to move upward. Since the first pin 224 is inserted into the first telescopic rod 221, it will drive the first telescopic rod 221 to move upward. When the first telescopic knob 22 is rotated into place, the first pin 224 will be fixed at the highest point of the first limiting spiral groove 2231, and the first telescopic rod 221 will be driven by the first pin 224 to retract into the first telescopic knob 22, and then the supporting member 20 can be moved toward the large hole of the gourd hole. After moving to the large hole of the gourd hole, the supporting member 20 can be taken out.

[0056] In summary, the disassembly of the support member 20 is now completed. The entire installation and disassembly process is tool-free and easy to operate.
