When the equipment needs to be installed, firstly, the mechanism is confirmed to be in a waiting state, namely, the cam wrench and the pull rod are in a straight line shape, a moving space far away from the wrench direction is released, at the moment, an outer convex groove on one side of a quick-assembly plate of the connecting equipment is placed into a base dovetail groove, an outer convex groove on the other side of the quick-assembly plate touches an inclined plane on the locking block and is pressed downwards, at the moment, the locking block is forced to move towards the direction far away from the cam wrench by the downward pressure, after the front edge of the quick-assembly plate crosses the highest point of the locking block, the front edge of the quick-assembly plate enters the dovetail groove between the locking block and the base under the action of gravity and a spring, closing self-locking is realized under the action of an inner pull rod spring, at the moment, the outer convex groove of the quick-assembly plate is limited by the dovetail groove on one side of the base plate and the locking block, so that the quick-assembly plate can only slide forwards and backwards and can not be separated, namely, the quick-assembly limiting state can be closed, the front-assembly plate can be convenient to move forwards and backwards, and the flexibility of the quick-assembly plate is increased, at the moment, the locking mechanism is in a closed but non-locking state, after the quick-assembly plate is in a proper position, the cam wrench is broken to be buckled close to one side of the locking block, the cam wrench is pulled to further tension the pull pin through the eccentric effect of the cam, and static friction force is formed on the contact surface between the quick-assembly plate and the base as well as between the quick-assembly plate and the locking block to drive the locking block to lock the quick-assembly plate. The cam spanner is pulled reversely, the cam spanner firstly returns to a state of self-locking and closing by virtue of the spring, the spanner is continuously moved, the vertical shaft pin on the cam spanner can abut against the outer side of the inner groove to form a lever taking the vertical shaft pin as a fulcrum, the pull rod is pushed to move in a direction of being away from the cam spanner in a reverse direction, the locking block is pushed open, and the quick-mounting plate is convenient to separate. The wrench is loosened, and the state of releasing the to-be-loaded state is returned. Through the structural design, the cam wrench is turned over to buckle and directly trigger self-locking, locking and releasing, so that the structural design is simplified, and meanwhile, the operation is convenient.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not to be understood as the limitation of the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
