[0054] S4, the locking plate 600 moves downward so that the locking plate 600 fits with the upper end of the tension column, the user rotates the clamping screw 614, the clamping screw 614 drives the clamping plate 611 to move, the clamping plate 611 fits with one side of the lifting rope 410, so that one end of the locking plate 600 is connected to the lifting rope 410, and the other end of the locking plate 600 is connected to the lifting rope 410, the user rotates the movable clamping seat 620, the movable clamping seat 620 locks the lifting rope 410, the user rotates and pulls the clamping block 633, and the clamping block 633 drives the connecting sleeve 632 to move The connecting sleeve 632 drives the connecting rod 636 to move, and the connecting spring 637 is compressed by the stopper. The user rotates the movable clamping plate 611, and the connecting sleeve 632 is inserted into the inside of the slot 634. The connecting sleeve 632 returns to its original position under the action of the connecting spring 637, and the clamping block 633 is inserted into the inside of the clamping groove 635, so that the movable connecting plate 630 is connected with the locking plate 600, and the locking plate 600 can be limited. The locking plate 600 fits with the upper end of the tension column, which enhances the locking effect, facilitates auxiliary lifting, and speeds up the rapid disassembly and assembly speed.

[0055] S5. The winding box 200 winds up the traction rope 300. Under the action of the pulley 122, the upward hoisting effect is enhanced. The traction rope 300 drives the hoisting plate 400 to move upward. The hoisting plate 400 facilitates the stable upward movement of the tension column through the hoisting rope 410.
