Abstract
The utility model discloses a fixed-point revolving T-shaped clamp and a locking piece and belongs to the technical field of machining accessories. The T-shaped clamp comprises a bolt which comprises a threaded rod and a flat head. The locking piece comprises a body. When the T-shaped clamp is used, working efficiency is improved, and the assembling of the T-shaped clamp and a T-shaped sliding groove is not influenced even when the T-shaped sliding groove is piled up with scrap iron. A through hole formed in the head of the locking piece and a containing space between two legs of the locking piece enable the locking piece to be matched with the T-shaped clamp to fill the T-shaped groove, and then self-locking of the T-shaped clamp at the assigned position can be achieved. When the T-shaped clamp is used, the T-shaped clamp can be dismounted through the inverse process of assembling the T-shaped clamp and the locking piece in the T-shaped sliding groove, and therefore the T-shaped clamp can be replaced.
