[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] In order to facilitate the locking and unlocking of items, refer to Figure 1 and Figure 2 As shown, it includes a housing 9, a multi-threaded screw 1, a nut, a guide groove 5 and a locking buckle. The multi-threaded screw 1 passes through the housing 9 from top to bottom, the nut is sleeved on the outside of the multi-threaded screw 1, the guide groove 5 is opened in the housing 9, and the locking buckle is installed on the outside of the nut; wherein, when the multi-threaded screw 1 rotates, it drives the nut to move up and down in the guide groove 5, so that the locking buckle fixed to the nut follows the up and down movement, and realizes rapid locking. The guide groove 5 is adapted to the shape of the nut, so that when the nut follows the rotation of the multi-threaded screw 1, the nut is rotationally limited, and the rotational motion is converted into linear motion, so that the nut can move up and down in the guide groove 5. The external pneumatic motor torque of the multi-threaded screw 1 is used and rotated, so that the nut installed on the outside of the multi-threaded screw 1 follows the rotation, and at the same time, the nut moves up and down under the action of the guide groove 5, so that the locking hook 8 fixed to the nut follows the nut to move up and down, so as to quickly lock and unlock the special closed buckle ring, which is used for locking and unlocking items in complex environments, and is convenient for quick access to on-site equipment.

[0017] In order to make the locking hook 8 quickly lock the object, refer to Figure 1 and Figure 2As shown, the power input end of the multi-threaded screw 1 is externally connected to the power output end of the pneumatic motor. The multi-threaded screw 1 has multiple pitches, which achieves the effect of low speed and multiple output, improves convenience, and can be rotated by the pneumatic motor. The outer side of the housing 9 is provided with a stopper 7, and the outer side of the stopper 7 is provided with a hexagon socket head screw 6, and the hexagon socket head screw 6 is set to four. The stopper 7 is fixed by installing the hexagon socket head screw 6, and the stopper 7 is set to two, and two hexagon socket head screws are set on each of the two stoppers 7. The stopper 7 is used to block the locking hook 8 to prevent it from rising too high. A limiting socket hexagon socket head screw 2 is also inserted into the outer side of the shell 9, and the limiting socket hexagon socket head screw 2 passes through the shell 9 and extends into the guide groove 5. The limiting socket hexagon socket head screw 2 is provided with a spring washer 3 and a flat washer 4 in sequence on the side facing the shell 9. The spring washer 3 is of standard type, and the flat washer 4 is of grade C. By adding the spring washer 3 and the flat washer 4, the stability of the limiting socket hexagon socket head screw 2 after installation is improved. The multi-head screw 1, the shell 9, the block 7 and the locking buckle are all made of stainless steel. The use of stainless steel material prolongs the overall service life. The threaded pair has a reliable locking coefficient without slipping or loose defects. When the locking hook 8 is pressed down, it can be quickly locked, which simplifies the transmission structure.

[0018] When in use, first connect the power input end of the multi-threaded screw 1 to the power output end of the external pneumatic motor torque, so that the multi-threaded screw 1 rotates accordingly, and the nut installed on the outside of the multi-threaded screw 1 rotates accordingly, and at the same time, the nut moves up and down under the action of the guide groove 5, so that the locking hook 8 fixed to the nut moves up and down with the nut, thereby quickly locking and unlocking the special closed buckle.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
