[0024] The seat body 10 is provided with a connection hole 11, and the seat body 10 is provided with a first guide structure 12. The first guide structure 12 can be located on the right side of the seat body 10 and opposite to the vertical hinge shaft 300. The first guide structure 12 can be an inclined surface. The seat body 10 can be provided with a receiving groove 13, and the right groove wall of the receiving groove 13 forms the first guide structure 12.

[0025] The locking block 20 can move laterally relative to the base body 10 , and a locking structure 21 for locking the vertical hinge shaft 300 is provided at the left end of the locking block 20 .

[0026] The locking block 20 may be provided with a limiting protrusion 23 , and the base body 10 may be provided with a limiting groove 14 , and the limiting protrusion 23 is inserted into the limiting groove 14 , so as to achieve lateral movement of the locking block 20 relative to the base body 10 .

[0027] The fastening block 30 has a waist hole 31 extending transversely, and the fastening block 30 has a second guide structure 32 matched with the first guide structure 12, and the second guide structure 32 can be located at the right end of the fastening block 30. The second guide structure 32 can be an inclined surface, and the inclination direction and inclination angle are the same as those of the first guide structure 12.

[0028] With the cooperation of the first guide structure 12 and the second guide structure 32 , the fastening block 30 can be moved obliquely toward the fastening block 30 .

[0029] The fastening block 30 can be placed in the receiving groove 13 and be restricted by the receiving groove 13, so that both sides of the fastening block 30 are restricted by the inner wall of the receiving groove 13, and the fastening block 30 can only move obliquely toward the bottom of the receiving groove 13 and toward the locking block 20.
