Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, this utility model proposes a gripper structure, including a plate 100, two grippers 200, a drive assembly 300, and a handle 400. Each of the two grippers 200 is provided with a component 201. The drive assembly 300 is installed on the plate 100 and is drivenly connected to the two grippers 200 respectively to drive the two grippers 200 to move closer or further apart. The handle 400 is installed on the plate 100 for gripping. By gripping the handle 400 and moving the components 201 on the two grippers 200 closer or further apart, the two grippers 200 are driven to move closer or further apart.

[0028] The specific implementation methods in this embodiment are as follows: The first implementation method uses the drive group 300 to drive the two grippers 200 on the plate 100 to move closer or further apart, so as to realize the automatic gripping function of the gripper structure. In the second implementation method, the operator holds the handle 400 and moves the components 201 on the two grippers 200 closer or further apart, which also realizes the automatic gripping function of the gripper structure. It should be noted that the drive group 300 does not have a self-locking function so that the second implementation method can be executed normally. The shape and structure of the two grippers are not limited and can be selected according to the actual application scenario.

[0029] In one embodiment of this application, the drive group 300 includes a drive motor 301, a gear 302, and two transmission groups 303. The drive motor 301 is mounted on the plate 100; the gear 302 is fixedly connected to the output end of the drive motor 301; the two transmission groups 303 are both mounted on the plate 100 and are respectively connected to the gear 302, and the two transmission groups 303 are respectively connected to the corresponding grippers 200.

[0030] It should be noted that the plate 100 includes two opposing first surfaces and second surfaces, and the plate 100 is also provided with a hole to connect the first surface and the second surface. The drive motor 301 is mounted on the second surface, and the output end of the drive motor 301 passes through the hole and is placed on the first surface. The gear 302 is fixed on the output end and is also placed on the first surface. Two transmission groups 303 are mounted on the first surface of the plate 100 and are connected to the gear 302 for transmission.

[0031] In another embodiment, the drive motor 301 can be mounted on the first surface of the plate 100, on the same surface as the two transmission groups 303. However, multiple gears 302 need to be provided so that the drive motor 301 is away from the movement area of ​​the two grippers 200. Alternatively, a synchronous belt can be used to connect the drive motor 301 and the gears 302, ensuring that the drive motor 301 is away from the movement area of ​​the two grippers 200 while ensuring the accurate transmission of the gears 302.

[0032] In one embodiment of this application, the transmission assembly 303 includes a slide table 3031, a slide rail 3032, and a rack 3033. The slide table 3031 is fixedly connected to the plate 100; the slide rail 3032 is slidably mounted on the slide table 3031, wherein the gripper 200 is fixed to the slide rail 3032; the rack 3033 is fixedly connected to the slide rail 3032 and meshes with the gear 302 for transmission.

[0033] It should be noted that the slide table 3031 is mounted on the plate 100 and serves as the fixed component, while the slide rail 3032 serves as the movable component and is slidably mounted on the slide table 3031. The grippers 200 are fixed to the end of the slide rail 3032, effectively reducing the volume of the entire gripper structure while expanding the unfolding range of the two grippers 200, thereby adapting to different sizes of objects to be gripped. The rack 3033 is also fixed on the slide rail 3032 and meshes with the gear 302 for transmission. It should be added that the two transmission groups 303 are respectively located above and below the gear 302. The racks 3033 in the two transmission groups 303 mesh with the upper and lower sides of the gear 302 respectively. When the gear 302 rotates counterclockwise or clockwise, the two racks 3033 will move closer or further away from each other along the length of the slide rail 3032, thereby causing the grippers 200 to move closer or further away from each other.

[0034] In one embodiment of this application, the transmission assembly 303 further includes a fixing block 3034, and the gripper 200 is fixed to the slide rail 3032 by the fixing block 3034. A limiting block 3035 is provided on the fixing block 3034, and the limiting block 3035 is used to abut against the slide table 3031 to limit the sliding of the slide rail 3032 on the slide table 3031.

[0035] See appendix Figure 2 and attached Figure 3 It should be noted that since the slide rail 3032 does not have a limiting structure, it is easy for the gripper 200 to move excessively during use, causing the slide rail 3032 to disengage from the slide table 3031 or to apply excessive clamping force to the object being held. Therefore, a corresponding limiting block 3035 is provided on the end of the slide rail 3032, and the setting position of the limiting block 3035 is the same as that of the gripper 200.

[0036] In one embodiment of this application, an extension plate 2011 and a lever 2012 are provided. The extension plate 2011 is fixedly connected to the gripper 200, and the lever 2012 is fixedly connected to the extension plate 2011. It should be noted that the methods of fixing the extension plate 2011 and the gripper 200 include, but are not limited to, screw fitting, welding, riveting, or integral molding. In this embodiment, the method of fixing the extension plate 2011 and the gripper 200 is preferably integral molding.

[0037] The dial 2012 includes a ring.

[0038] In one embodiment of this application, the handle 400 is provided with a plurality of grooves 401.

[0039] It should be noted that the design of multiple grooves 401 adapts to the hand grip posture, improving the comfort and stability of holding the gripper structure.

[0040] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
