Anti-looseness twist lock
The invention discloses an anti-looseness twist lock which comprises a lock shaft, a lock shell, a handle and a fixing device. The handle comprises a first supporting bar and a second supporting bar. The lock shell comprises a first groove and a second groove. The lock shaft penetrates into the lock shell. The top end of the lock shaft protrudes out of the other end of the lock shell and is in a conic shape. The other end of the second supporting bar can rotate around a fixing center, wherein the end connected with the first supporting bar serves as the fixing center. The second supporting bar penetrates through the first groove and can rotate along the first groove and drive the first supporting bar and the lock shaft to rotate at the same time. In the initial state, the second supporting bar is located at one end of the first groove. By the adoption of the anti-looseness twist lock, the handle can be bent, after the lock shaft is adjusted to the assigned state, the handle is bent, the situation that the lock shaft is displaced due to the displacement of the handle when the handle rubs with other objects can be prevented, and the looseness probability of the anti-looseness twist lock is reduced.
