[0013] In the figure: 1. Cylinder body fixing seat; 2. Floating lifting ear; 3. Locking roller; 4. Pin shaft; 5. Upper top plate; 6. Lifting screw; 7. Polyurethane pad; 8. Piston; 9. Cylinder. DETAILED DESCRIPTION

[0014] 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.

[0015] For quick unlocking, refer to Figure 1 As shown, it includes an upper top plate 5, a piston 8, a cylinder 9, a pin 4 and a locking roller 3. The piston 8 is arranged in the cylinder 9, and the pin 4 is arranged at the end of the piston 8 away from the cylinder 9. The locking roller 3 is arranged on the upper top plate 5 through a floating ear 2. The piston 8 is driven by the cylinder 9 to insert the pin 4 into the locking roller 3 to complete the locking. By positioning the upper top plate 5 slightly accurately, the cylinder 9 drives the piston 8 to move toward the side away from the cylinder 9, driving the pin 4 to be inserted into the arc groove opened in the locking roller 3, and then using the tightening screw 6 to adjust the locking clearance of the pin 4 to meet the locking state, the original huge structure is simplified, the space occupied is small, the processing time is saved, and the energy and consumption are reduced.

[0016] In order to facilitate the stability of cylinder 9 during operation, refer to Figure 1 As shown, the floating lifting lug 2 is arranged on the lower surface of the upper top plate 5, and the locking roller 3 is arranged on the floating lifting lug 2. The locking roller 3 is provided with an arc groove for inserting the pin shaft 4. As the cylinder 9 operates, the piston 8 is driven to move, and the pin shaft 4 arranged on the head of the piston 8 is inserted into the arc groove provided in the locking roller 3, so as to facilitate quick locking and improve convenience. The upper surface of the upper top plate 5 is provided with a plug hole, and a tightening screw 6 for adjusting the locking clearance of the pin shaft 4 is inserted into the plug hole. By adjusting the tightening screw 6, the locking clearance of the pin shaft 4 is adjusted to meet the locking state, so as to achieve the effect of quick locking. A cylinder body fixing seat 1 is arranged on the outside of the cylinder 9, and the cylinder 9 is supported by the cylinder body fixing seat 1 to improve the stability of the cylinder 9 during operation. A polyurethane pad 7 is also provided on the lower surface of the upper top plate 5, and the end of the polyurethane pad 7 away from the upper top plate 5 is in contact with the cylinder body fixing seat 1. The use of the polyesteramine pad can effectively reduce the vibration and noise during the operation of the cylinder 9, avoiding excessive influence on unlocking and locking.

[0017] When in use, first, the upper top plate 5 is positioned slightly accurately, and the cylinder 9 drives the piston 8 to move toward the side away from the cylinder 9, driving the pin 4 to be inserted into the arc groove opened in the locking roller 3, and then the tightening screw 6 is used to adjust the locking clearance of the pin 4 to meet the locking state. When the piston 8 moves in the cylinder 9 toward the cylinder 9, the pin 4 withdraws from the arc groove of the locking roller 3. At this time, the upper top plate 5 is freely loosened and the unlocking is completed.

[0018] 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.
