One end of the first connecting rod 25 is rotatably connected to the driving member, and the other end of the first connecting rod 25 is rotatably connected to the rotating portion 232. In this embodiment, the first connecting rod 25 is an L-shaped rod body, and includes a horizontal portion and a vertical portion, and a corner portion connecting the horizontal portion and the vertical portion. The horizontal part is connected with the driving part in a rotating mode, and the driving part can be directly connected with the horizontal part or connected with the horizontal part through other transition parts. The vertical portion is rotatably connected to the rotation position 232, and the rotation plane is a vertical plane.
One end of the second connecting rod 26 is rotatably connected to the first connecting rod 25, and the other end of the second connecting rod 26 is disposed above the fixing position 231 and is provided with the movable chuck 22.
The second connecting rod 26 is a straight rod, one end of which is rotatably connected to the corner of the first connecting rod 25, and the other end of the second connecting rod 26 is provided with a movable chuck 22.
The driving member drives the first connecting rod 25 to rotate or swing around the rotation position 232, and drives the second connecting rod 26 to rotate or swing around the rotation position 232, so that the movable chuck 22 at the other end of the second connecting rod 26 is close to or far away from the fixed chuck 21. When the movable chuck 22 approaches the fixed chuck 21, the clamp is closed to clamp a workpiece, which is the rack-and-pinion steering gear 40 in this embodiment, although the workpiece is not limited to the rack-and-pinion steering gear 40. When the movable chuck 22 is away from the fixed chuck 21, the clamp is opened to allow the workpiece to be placed in or removed from the clamp.
