Through the transmission structure of the connecting rod and the transmission member 7, the carrier clamping device only needs one driving member to drive, and no synchronous debugging is required, and the setting of the two connecting rods makes the clamping stroke larger.

[0026] The bottom plate 1 is flat as a whole, and the movable assembly 2 is located on one side of the bottom plate 1. The movable assembly 2 includes a first movable plate 25 and a second movable plate 26 which are parallel to each other. Two linear slide rails 11 are arranged in parallel on the bottom plate 1. The first movable plate 25 and the second movable plate 26 are both slidably connected to the bottom plate 1 through the slide rails 11, so that the first movable plate 25 and the second movable plate 26 are parallel to each other. The first movable plate 25 and the second movable plate 26 are both connected with a clamping member 23. Specifically, the clamping member 23 is cylindrical and can be used to match the arc-shaped bayonet of the clamped fixture. When the posture of the clamped fixture deviates slightly from the standard posture, the cylindrical clamping member 23 clamps the arc-shaped bayonet, so that the clamped fixture can be moved to the standard posture.

The transmission member 7 and the first linear drive member 5 are located on opposite sides of the base plate 1, and the transmission member 7 is rotatably connected to the middle position of the base plate 1. The first movable plate 25 is connected to the connecting block 24, the connecting block 24 is hinged with the first connecting rod 71, and the hinge side of the connecting block 24 and the hinge side of the first connecting rod 71 are located in the same plane, so that the first connecting rod 71 and the base plate 1 are arranged in parallel. The connection mode between the second movable plate 26 and the second connecting rod 72 is the same as the connection mode between the first movable plate 25 and the first connecting rod 71, which will not be described again. The bottom plate 1 is provided with an opening at a position corresponding to the moving path of the connecting block 24, and the opening is used to avoid the connecting block 24 to prevent the connecting block 24 from colliding with the bottom plate 1 during movement.

[0028] Reference Figure 4 and Figure 5As shown, a fixed sleeve 61 is connected to the middle position of the base plate 1, and the fixed sleeve 61 and the first linear drive member 5 are located on the same side of the base plate 1. The fixed sleeve 61 is cylindrical as a whole, and a fixed shaft 62 is provided inside the fixed sleeve 61, and a bearing 6 is sleeved on the fixed shaft 62. The bearing 6 is a double-row angular contact ball bearing. The bearing 6 is located between the fixed shaft 62 and the fixed sleeve 61.

[0032] When in use, the first linear drive member 5 drives the first movable plate 25 to move in the direction close to the bearing 6. The movement of the first movable plate 25 can drive the first connecting rod 71 to move in the direction of the second movable plate 26. The first connecting rod 71 can drive the transmission member 7 to rotate, thereby driving the second connecting rod 72 to move in the direction of the first movable plate 25, thereby enabling the clamping member 23 to complete the clamping action.
