[0018] Reference Figure 1-5 , a rotary clamping jaw, characterized in that it includes a drive shaft 1, and the outside of the drive shaft 1 is respectively sleeved with an upper part 2, a middle part 3 and a lower part 4 from top to bottom.

[0019] The upper part 2 includes a synchronous pulley 5, and the synchronous pulley 5 is driven to rotate by an external component. The inner center of the synchronous pulley 5 is connected with a barrel shaft 6 by interference fit. The top of the barrel shaft 6 is inserted with a shaft end 7, which is convenient for fixing the device. A tensioning member 8 is inserted into the interior of the shaft end 7. The tensioning member 8 improves the stability of the transmission system and reduces noise. The outer surface of the top of the barrel shaft 6 is provided with a ring 20 located between the synchronous pulley 5 and the shaft end 7. The rotation of the synchronous pulley 5 drives the barrel shaft 6 to rotate, and the rotation of the barrel shaft 6 drives the lower part 4 to rotate.

[0020] The middle part 3 includes a bearing seat 9, and the upper and lower ends of the inner part of the bearing seat 9 are interference connected with bearings 10. The bearings 10 can prevent the bearing seat 9 from rotating when the cylindrical shaft 6 rotates. A spacer 11 is provided between the two bearings 10, and the spacer 11 can support and isolate the bearing 10. A copper sleeve 12 is interference connected on the inner side of the bottom of the cylindrical shaft 6, and a baffle 13 is interference connected on the outer surface of the drive shaft 1. A spring 15 is provided on the outer surface of the drive shaft 1 between the copper sleeve 12 and the baffle 13. When the drive shaft 1 moves downward, the baffle 13 drives the spring 15 to be squeezed. When the design pressure on the drive shaft 1 is no longer applied, the baffle 13 and the drive shaft 1 are driven upward by the elastic force of the spring 15 itself.

[0021] The lower part 4 includes a clamping jaw seat 14, and the top of the clamping jaw seat 14 is threadedly connected to the bottom of the cylindrical shaft 6. Both ends of the bottom of the driving shaft 1 are movably connected to the connecting rod 16 through the shaft. The left and right ends of the bottom of the clamping jaw seat 14 are movably connected to the connecting rod 16. The connecting rod 16 movably connected to it is driven to rotate by the up and down movement of the driving shaft 1, and the rotation of the connecting rod 16 drives the clamping jaws 17 movably connected to it to move inward or outward at the same time, thereby realizing clamping.

[0022] A bushing 18 is fixed to the outer surface of the drive shaft 1. The bushing 18 plays a protective role in the equipment and can effectively reduce wear, vibration and noise.

[0023] The outer surface of the cylindrical shaft 6 is sleeved with a cover 19 located between the synchronous pulley 5 and the bearing 10, and the cylindrical shaft 6 is supported by the cover 19.

[0024] When the device is in use, downward pressure is applied to 1 by an external cam pushing element (not shown) to move it, and at the same time, the baffle 13 squeezes the spring 15. The downward movement of the drive shaft 1 drives the connecting rod 16 to rotate while also driving the clamping jaw 17 to move inward or outward at the same time, thereby achieving clamping. When the thrust applied to the drive shaft 1 stops, the spring 15 applies thrust to the baffle 13 to return it to its initial position, and at the same time the clamping jaw 17 returns to its initial position. When the clamping jaw 17 needs to be rotated, the synchronous pulley 5 is driven to rotate by the external rotating component. The rotation of the synchronous pulley 5 drives the barrel shaft 6 and the clamping jaw seat 14 to rotate, and the rotation of the clamping jaw seat 14 drives the clamping jaw 17 and the drive shaft 1 to rotate. At this time, the bearing seat 9 is kept stationary by the bearing 10.
