When the locking structure 30 is in the locked state, the locking protrusion 32 abuts against the second triangular plate 22, which can fix the triangular frame 20 on the base 10 while enabling the triangular frame 20 to compress the buffer layer 2121 arranged on the first bonding surface 212, so that the buffer layer 2121 has a certain rebound force. When the locking structure 30 is switched to the unlocked state, the rebound force of the buffer layer 2121 can help the triangular frame 20 to smoothly separate from the base 10. In addition, during long-term use, the buffer layer 2121 can buffer the collision between the triangular frame 20 and the base 10 in the bumpy state, thereby reducing wear and damage caused by the collision.

[0076] In the embodiment of the present application, the buffer layer 2121 is made of elastic material EVA foam, which can not only provide sufficient rebound force for the triangular frame 20 to smoothly separate from the base 10, but also reduce production cost. In other embodiments of the present application, the elastic material can also be polyurethane foam, polyester fiber foam, rubber foam, etc., which has good elasticity.

[0077] Specifically, in the embodiment of the present application, two buffer layers 2121 are arranged, which can not only provide sufficient rebound force for the tripod 20 to smoothly separate from the base 10, but also reduce production cost. In other embodiments of the present application, the number of buffer layers 2121 can be multiple, specifically, three, four, five, etc., which can provide sufficient rebound force for the tripod 20 to smoothly separate from the base 10.
