[0008] Advantages of the present invention: By providing a threaded through-hole, a energy storage screw rod, a compression spring, a pressure rod and a square connecting rod, and using the threaded rotational connection between the energy storage screw rod and the threaded through-hole, the energy storage screw rod can be rotated by an external force, so as to realize the vertical movement of the energy storage screw rod. Furthermore, through the movement of the energy storage screw rod, the pressure rod and the square connecting rod are driven to move, and the compression spring contracts to complete the energy storage operation; By providing an inverted tooth groove b, a trigger compression rod, a connection hole b, a spring b, a fixed block b and a pin b, when disassembling the energy storage screw rod after the energy storage is completed, the pulling force of the spring b can be utilized to realize the mating socket connection between the outer end of the pin b and the inverted tooth groove b.

The energy release rod 3 is vertically arranged as a whole. Its upper end is located inside the groove a23 and is rotatably connected to the groove a23 through a pin shaft. A connecting hole a31 is horizontally provided in the middle. One end of the latch a27 is located in the inverted tooth groove a12 and is cooperatively sleeved with the inverted tooth groove a12. The other end is located in the connecting hole a31 and is rotatably connected to the connecting hole a31 through a pin shaft. A spring a32 is horizontally arranged above the latch a27. The spring a32 is fixedly arranged between the fixing block a25 and the energy release rod 3. A square connecting rod 7 is vertically slidably arranged inside the mounting groove b22. A plurality of inverted tooth grooves b71 are evenly arranged on the left side surface of the square connecting rod 7. Its upper end is located above the mounting rod 2 and a pressure rod 72 is horizontally fixedly arranged. The compression spring 4 is sleeved outside the square connecting rod 7. Its upper end is fixedly connected to the lower surface of the pressure rod 72, and its lower end is fixedly connected to the upper surface of the mounting rod 2. The trigger compression rod 5 is vertically arranged. Its upper end is located inside the groove b24 and is rotatably connected to the groove b24 through a pin shaft. A connecting hole b51 is horizontally fixedly arranged in the middle. One end of the latch b28 is located in the inverted tooth groove b71 and is cooperatively sleeved with the inverted tooth groove b71. The other end is located in the connecting hole b51 and is rotatably connected to the connecting hole b51 through a pin shaft. A spring b52 is horizontally arranged above the latch b28. The spring b52 is fixedly arranged between the fixing block b26 and the trigger compression rod 5. The energy storage lead screw 6 is vertically threaded and rotatably passed through the threaded through hole 11.

[0017] A release head 33 is horizontally and fixedly arranged at the lower end of the left side surface of the energy release rod 3, and a hanging and pressing head 53 is horizontally and fixedly arranged at the lower end of the left side surface of the trigger pressing rod 5. By providing the release head 33 and the hanging and pressing head 53, it is convenient to perform hanging and disassembly operations when the present invention is used horizontally; the upper end of the energy storage screw rod 6 is located above the main rod 1 and is horizontally and fixedly connected with an auxiliary rotating rod 61, and the auxiliary rotating rod 61 can be used to increase the convenience of the rotation operation of the energy storage screw rod 6.

[0018] Before the present invention is used, energy storage operation needs to be carried out on it, and the specific operation is as follows: First, rotate the energy storage screw rod 6 by an external force. By using the threaded rotational connection between the energy storage screw rod 6 and the threaded through hole 11, while the energy storage screw rod 6 rotates, vertical movement can be carried out. During this process, by using the movement of the energy storage screw rod 6, the pressure rod 72 and the square connecting rod 7 can be driven to move, and the compression spring 4 can be contracted, thereby completing the energy storage operation. Then, by using the pulling force of the spring b52, the outer end of the pin b28 can be fitted and sleeved with the inverted tooth groove b71, so as to complete the limiting of the square connecting rod 7 through the trigger pressing rod 5 and the pin b28. By adopting this structure, when the energy storage screw rod 6 is removed later, the pressure rod 72 and the square connecting rod 7 can be prevented from resetting under the action of the compression spring 4, thereby realizing energy storage retention.

[0019] When the present invention is in use, first, rotate the energy storage screw rod 6 in the reverse direction, remove the energy storage screw rod 6 from the upper end of the main rod 1. Then, through the insulating rod and using the opening formed by the cooperation of the pressure rod 72 and the horizontal part of the L-shaped structure of the main rod 1, the whole of the present invention is hung on the outside of the live body. After that, pry the trigger pressing rod 5 through the insulating rod, so that the trigger pressing rod 5 rotates counterclockwise around the pin shaft at its upper end. During this process, by using the rotational connection between the pin b28 and the connection hole b51 and the horizontal sliding connection between the fixed block b25 and the pin b28, the pin b28 can be driven to perform horizontal lateral movement while the trigger pressing rod 5 rotates, thereby releasing the fitting and sleeving between the pin b28 and the inverted tooth groove b71. At this point, through the thrust generated when the compression spring 4 expands, the pressure rod 72 and the square connecting rod 7 can be driven to perform vertical movement, so as to realize the clamping and limiting hanging of the present invention on the outside of the live body by using the cooperation between the pressure rod 72 and the horizontal part of the L-shaped structure of the main rod 1.

[0020] When the present invention is disassembled, the insulating rod can be used to pry the energy release rod 3, so that the energy release rod 3 rotates counterclockwise around the pin shaft at its upper end. At this time, by using the rotational connection between the insertion pin a27 and the connection hole a31, and the lateral sliding connection between the fixed block a25 and the insertion pin a27, the insertion pin a27 can be driven to move horizontally and laterally while the energy release rod 3 rotates, thereby releasing the mating socket connection between the insertion pin a27 and the reverse tooth groove a12. After that, with the release of the socket connection between the insertion pin a27 and the reverse tooth groove a12, the entire mounting rod 2 can drive the pressure rod 72 and the square connecting rod 7 to slide downward along the main rod 1, thereby releasing the limiting hanging connection between the horizontal part of the L-shaped structure of the main rod 1 and the pressure rod 72 in cooperation with the outside of the live body; Generally speaking, the present invention has the advantages of reasonable structural design, time-saving and convenient operation.
