[0003] We have developed a spanner type locking structure which uses the spanner to press down the bracket buckle, and then the hook structure on the bracket buckle cooperates with the clamping groove on the upper end of the carrier to realize the quick connection of the quick release support and the carrier. When the spanner presses down the bracket buckle, the spanner needs to be locked and positioned by the floating lock ball mechanism. The existing technology has the problem that when the spanner needs to be unlocked, torque needs to be applied to the spanner, so that the lock ball in the floating lock ball mechanism is released from the corresponding lock ball cooperation groove. The size of the spanner part is small, and it is not convenient for the operator to directly apply torque to unlock it. SUMMARY
