[0030] When the present invention is used in a specific way, during the loading operation, the second support block 121 rotates in the vertical direction of the loading process under the action of the workpiece 300, thereby avoiding the workpiece 300. After the workpiece 300 reaches the position, the second support block 121 moves counterclockwise along the vertical direction of the second hinge shaft 122, thereby hooking the workpiece 300, and then moving the bracket 110 until the workpiece 300 coincides with the stop block 111. When the external pneumatic lifter is operated to lift the workpiece 300 upward, the workpiece 300 drives the bracket 110 downward due to its own gravity, but because the first hinge seat 113 is stationary, one end of the second hinge seat 114 moves downward along with the bracket 110 under the action of the linear bearing 107 and the compression spring 108, and the front end of the second hinge seat 114 moves in the long pin hole of the pressure arm 116, thereby driving the pressure arm 116 and the pressure block 117 When the workpiece 300 moves downward, the pressing block 117 cooperates with the second supporting block 121 to realize automatic pressing, so that the workpiece 300 can be smoothly transferred to other equipment or a loading vehicle; when unloading, after the workpiece 300 reaches the designated position, the worker operates the controller of the external pneumatic lifter with one hand and puts the other hand on the installation connection block 207 and the hand-pull rotation block 204, first controlling the external pneumatic lifter to move downward, and through the action of the compression spring 208, the bracket 110 moves upward relative to the installation block 106, realizing the pressing arm 116 and the pressing block 117. The lifting movement is performed upward, and the compressed state is changed to the open state. When the bracket 110 moves down to a certain stage, the bracket 110 is moved to the left until the first support block 112 is pulled out. The worker pulls the installation connection block 207 and the hand-pull rotating block 204 to overcome the tension of the tension spring 208 to make the first connecting shaft 220, the second connecting shaft 202, and the connecting shaft 203 move upward, thereby driving the second support blocks 121 on both sides to rotate respectively. At this time, the bracket 110 is also moved upward by the external pneumatic lifter, so that the second support block 121 is separated from the workpiece 300, thereby completing the separation of the workpiece 300. The worker releases his hand, and the elastic action of the tension spring 208 makes the first connecting shaft 220, the hand-pull rotating block 204, the installation connection block 207 and the second support block 121 automatically reset. The operation is simple and easy to use, which is conducive to improving the safety of the equipment, reducing the occurrence of safety accidents, ensuring production safety, and can reduce production costs and improve production efficiency.
