[0024] The folding component 23 includes a lower connecting rod 231 , the top of which is rotatably connected to an upper connecting rod 232 , an insertion rod 233 is inserted into the left side of the upper connecting rod 232 through a guide groove, and the end of the insertion rod 233 is inserted into the lower connecting rod 231 through a slot.

[0025] The outer side of the insert rod 233 is connected with a shift block 234 , and the shift block 234 passes through the interior of the upper connecting rod 232 through a limiting groove, and an arc-shaped inner concave surface is formed on the outer side of the bottom end of the shift block 234 .

[0026] The right side of the lower connecting rod 231 is connected with a restraining assembly 3 , and the restraining assembly 3 includes a ring plate 31 connected and fixed to the lower connecting rod 231 , and a slit is formed on a side of the ring plate 31 .

[0027] An adjusting bolt 32 is inserted through a threaded hole on the outer side of the ring plate 31 , and a rubber pressing plate 33 is rotatably connected to the end of the adjusting bolt 32 .

[0028] A threaded pin 42 is inserted through a threaded hole on the outer side of the adjustment sleeve 41 , and the shaft end of the threaded pin 42 abuts against the surface of the upper connecting rod 232 . The top end of the upper connecting rod 232 is covered with a cap 25 .

[0029] The docking component 44 includes a nut 441 , which passes through a side of the suspension plate 43 through a through hole, and a threaded insert shaft 442 is threadedly sleeved on the outer side of the shaft end of the nut 441 .

[0030] The foldable design between the lower connecting rod 231 and the upper connecting rod 232 can facilitate the staff to fold the upper connecting rod 232 and store it. When the lower connecting rod 231 and the upper connecting rod 232 are placed upright, the plug rod 233 can be movably inserted into the slot of the lower connecting rod 231 to ensure the docking stability between the lower connecting rod 231 and the upper connecting rod 232.
