[0006] Preferably, the ball is adapted to the first groove and the second groove.

[0007] Preferably, guide positions are provided at both ends of the gripper surface, and guide blocks are fixedly connected to both ends of the gripper surface, with the guide blocks slidably connected to the guide positions.

[0008] Preferably, a driving component is movably connected within the movable opening, and a driving block is fixedly connected to the surface of the driving component at a position opposite to the gripper opening.

[0009] Preferably, the rear end face of the gripper is provided with a drive groove adapted to the drive block, and the drive block is slidably connected in the drive groove.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1-4 This is a schematic diagram of a preferred embodiment of a three-jaw cylinder of the present invention. In this embodiment, a three-jaw cylinder includes a cylinder body 1, which has a movable port 11. Three gripper ports 12 are evenly distributed around the movable port 11 on the surface of the cylinder body 1. A driving member 3 is movably connected in the movable port 11. A driving block 31 is fixedly connected to the surface of the driving member 3 at a position opposite to the gripper ports 12. Through the back-and-forth movement of the driving member 3, grippers 2 are slidably connected in the gripper ports 12. A first sliding groove 121 is formed on the surface of the gripper ports 12, and a second sliding groove 21 is formed on the bottom surface of the grippers 2 at a position opposite to the first sliding groove 121. A plurality of balls 4 are arranged between the first sliding groove 121 and the second sliding groove 21, thereby reducing the friction between the gripper ports 12 and the surface of the grippers 2 by utilizing the balls 4, thereby reducing wear, improving service life and accuracy, and improving the synchronization between the three grippers 2.

[0025] In this embodiment, the ball bearing 4 is adapted to the first slide groove 121 and the second slide groove 21. This structural design allows the ball bearing 4 to better cooperate with the first slide groove 121 and the second slide groove 21, effectively avoiding the possibility of the gripper 2 shaking during the sliding process.

[0026] In this embodiment, guide positions 122 are provided at both ends of the surface of the gripper opening 12, and guide blocks 22 are fixedly connected to both ends of the surface of the gripper 2, and the guide blocks 22 are slidably connected to the guide positions 122. This structural design serves to guide the gripper 2 during its sliding process within the gripper opening 12.

[0027] In this embodiment, a driving component 3 is movably connected within the movable opening 11. A driving block 31 is fixedly connected to the surface of the driving component 3 at a position opposite to the gripper opening 12. A driving groove 23 adapted to the driving block 31 is opened on the rear end face of the gripper 2, and the driving block 31 is slidably connected within the driving groove 23. During the extension and retraction movement of the driving component 3, the angled engagement between the driving block 31 connected to it and the driving groove 23 drives the gripper 2 to slide within the gripper opening 12.

[0028] In this embodiment, the top surface of the gripper 2 is provided with a plurality of mounting holes 24, through which different types of clamps can be installed, giving it good compatibility.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
