When the piston 14 slides to the uppermost end, the lubricant can be injected into the oil injection pipe 12 through the oil injection port 13, so that the pawl body 4 can move stably. This mechanism is very convenient for maintaining the pawl body 4 and is very convenient to use. Pull the second The pulling block 25 can make the insertion rod 22 move synchronously. When the insertion rod 22 moves to the rightmost position, the rotating arm 1 can be removed from the side of the connecting block 18. Conversely, when the insertion rod 22 is aligned with the slot 19, the second pulling block 25 is released, and the limiting ring 23 can drive the insertion rod 22 to enter the slot 19 under the elastic force of the second spring 24. At this time, the rotating arm 1 can be fixed on the side of the connecting block 18. This structure is very convenient for removing the rotating arm 1 for maintenance. This structure only needs to fix the back of the connecting block 18 to the motor output end of the application scenario.
