[0019] The following detailed description, with reference to the accompanying drawings, further illustrates the structure and other aspects of the wire clamping device of this utility model.

[0020] like Figure 1 and Figure 2 As shown, the wire clamping device of this utility model includes a frame 1, a drive unit 2, and multiple clamping units 3. The drive unit 2 is used to drive the clamping units 3 to work, and the multiple individual clamping units 3 are used to clamp the wire 10 respectively. The clamping units 3 and the drive unit 2 are both mounted on the frame 1.

[0021] In a specific embodiment, a movable plate 11 is provided on the frame 1. The movable plate 11 reciprocates relative to the frame 1 via a sliding groove and a sliding rail provided on the movable plate 11 and the frame 1. The drive unit 2 has a drive rod 21, which is connected to the lower end of the movable plate 11. When the drive unit 2 drives the drive rod 21 to move up and down reciprocally, it in turn drives the movable plate 11 to move up and down reciprocally. The upper end of the frame 1 is provided with a positioning groove 13 for positioning the wire 10.

[0022] In this embodiment, movable plates 11 are provided on both sides of the frame 1, and the same number of clamping parts 3 are provided on both sides of the frame 1.

[0023] like Figure 3 As shown, in one embodiment, the clamping part 3 includes a fixed clamping member 31, a movable clamping member 32, a rotary drive member 33, and a push-pull part 34. The fixed clamping member 31 is fixedly mounted on the frame 1. Before clamping the wire 10, the wire 10 is first placed on the fixed clamping member 31. The positioning groove 13 is located at the fixed clamping member 31, and the bottom surface of the positioning groove 13 is flush with the surface of the fixed clamping member 31. The number of positioning grooves 13 is the same as the number of fixed clamping members 31. When placing the wire 10, the positioning groove 13 can position the wire 10 in a predetermined position, which facilitates the clamping of the wire by the fixed clamping member 31 and the movable clamping member 32.

[0024] The movable clamping member 32 is rotatably mounted on the frame 1. When rotated, the movable clamping member 32 can close with the fixed clamping member 31 to clamp the wire 10, or separate from the fixed clamping member 31 to facilitate the removal of the wire 10. The movable clamping member 32 is provided with teeth 321 (first teeth). The rotary drive member 33 is rotatably mounted on the frame 1 and has teeth 331 (second teeth). The teeth 321 and 331 mesh with each other, thereby driving the movable clamping member 32 to rotate when the rotary drive member 33 rotates. The other end of the rotary drive member 33 is pivotally connected to the upper end of the push-pull portion 34 via a pivot 35. The lower end of the push-pull portion 34 is rotatably mounted on the movable plate 11. In a preferred embodiment, the frame 11 is provided with an arc-shaped guide groove 12, and at least a portion of the pivot 35 is located within the guide groove 12.

[0025] In one embodiment, the push-pull part 34 further comprises a first sleeve 341, a second sleeve 342, an intermediate movable part 343, and an elastic part 344. One end of the intermediate movable part 343 is located in the first sleeve 341 and can move in the first sleeve 341 within a limited range. The other end of the intermediate movable part 343 is located in the second sleeve 342 and can move in the second sleeve 342 within a limited range. The first sleeve 341 is pivotally connected to one end of the rotary driving part 33 through the pivot 35, and the second sleeve 342 is rotatably mounted on the movable plate 11. The elastic part 344 is a compression spring, one end of which abuts against the first sleeve 341, and the other end of which abuts against the second sleeve 342, thereby providing an elastic force between the first sleeve 341 and the second sleeve 342.

[0026] In a specific embodiment, the first sleeve 341 and the second sleeve 342 are each provided with a sliding groove 345, and the two ends of the intermediate movable part 343 are each provided with a limiting protrusion 346, which is arranged in the sliding groove 345, so that the two ends of the intermediate movable part 343 move in the first sleeve 341 and the second sleeve 342 within a limited range.

[0027] As shown in Figure 4 and Figure 5 , when the wire clamping device is working, the movable clamping part 32 is in an open state, and the operator first places the wire 10 on the fixed clamping part 31. The driving part 2 drives the driving rod 21 to move upwards and drives the movable plate 11 to move upwards along the frame 1, as shown by the arrow in Figure 5 . The movable plate 11 drives the push-pull part 34 to move upwards, the push-pull part 34 drives the rotary driving part 33 to rotate, and the rotary driving part 33 drives the movable clamping part 32 engaged therewith to rotate. When the movable clamping part 32 rotates, the fixed clamping part 31 is closed, thereby clamping the wire 10 in the middle. When clamping the wire 10, the push-pull part 34 can be adjusted in extension and retraction, so that each movable clamping part 31 can contact the wire 10, thereby each clamping part 3 can effectively clamp the wire 10.

[0028] When it is needed to open the clamping part 3, the driving part 2 drives the driving rod 21 to move downwards and drives the movable plate 11 to move downwards along the frame 1. The movable plate 11 drives the push-pull part 34 to move downwards, and each component of the clamping part 3 returns to the open state.

[0029] The above embodiments are only used to illustrate the concept and scope of the utility model, and are not used to limit the protection scope of the utility model. Modifications, equivalent replacements, and other ways of improvement made to the above embodiments, which are obvious to those skilled in the art, are also within the concept of the utility model. The protection scope and concept of the utility model are specifically defined by the claims.
