The top of the vertical rod 603 is respectively abutted against the top surface of the inner wall of the claw, and the two barbs are respectively abutted against the two sides of the anti-slip groove 604. The anti-slip groove 604 increases the friction between the vertical rod 603 and the buckle mechanism 8 to prevent the vertical rod 603 from sliding or loosening during use, thereby improving the stability of the connection.
