[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0029] Example 1
[0030] like Figure 1-4 As shown, this embodiment includes a support plate, on which a first adjustment component 40 and a second adjustment component 50 are provided. The first adjustment component 40 and the second adjustment component 50 are mirror images of each other and can clamp the workpiece. Thus, by setting the first adjustment component 40 and the second adjustment component 50, the distance between the first adjustment component and the second adjustment component can be adjusted according to the size of the workpiece being processed, thereby achieving the clamping of workpieces of different sizes.
[0031] The support plate includes a first support plate 20 and a second support plate 30; a support base 10 is provided at the bottom of the support plate, and the first support plate 20 and the second support plate 30 are mirror images disposed on the support base 10; in this embodiment, the first support plate 20 and the second support plate 30 are fixedly disposed on the support base 10, and there is a gap between the first support plate 20 and the second support plate 30.
[0032] The first adjustment component 40 is disposed on the first support plate 20, and the second adjustment component 50 is disposed on the second support plate 30. In this embodiment, the first adjustment component 40 and the second adjustment component 50 are symmetrically arranged and respectively disposed in the middle of the first support plate 20 and the second support plate 30 in the lateral direction.
[0033] Both the first adjustment component 40 and the second adjustment component 50 include a slide groove 31 and a slider 32 disposed on the slide groove 31. In this embodiment, the slider 32 is T-shaped, and the vertical part of the T-shaped slider 32 is slidably connected to the slide groove 31, so that the slider 32 can reciprocate within the slide groove 31.
[0034] The front end of the slider 32 is provided with a tiger's mouth 33. In this embodiment, the tiger's mouth 33 is square, so that it can clamp the square workpiece.
[0035] In one embodiment, the tiger's mouth 33 is arc-shaped, thereby enabling the clamping of a circular workpiece.
[0036] The rear end of the slider 32 is provided with a fixing block 34 that is fixedly connected to the slide groove 31. In this embodiment, the fixing block 34 is T-shaped, and the vertical part of the T-shaped fixing block 34 is fixedly connected to the slide groove 31, thereby the fixing block 34 restricts the sliding space of the slider 32 in the slide groove 31.
[0037] The fixing block 34 is provided with a transverse threaded hole 35. In this embodiment, the transverse threaded hole 35 is provided in the transverse part of the T-shaped fixing block 34 and passes through the transverse part of the T-shaped fixing block 34.

By controlling the rotation of the transverse screw 36, the slider 32 can slide in the slide groove 31 and drive the jaw 33 to clamp the workpiece.
[0039] Example 2
[0040] like Figure 1-4 As shown, this embodiment includes a support plate, on which a first adjustment component 40 and a second adjustment component 50 are provided. The first adjustment component 40 and the second adjustment component 50 are mirror images of each other and can clamp the workpiece.
[0041] The support plate includes a first support plate 20 and a second support plate 30. A support base 10 is provided at the bottom of the support plate.

[0042] The first adjustment component 40 is disposed on the first support plate 20, and the second adjustment component 50 is disposed on the second support plate 30. In this embodiment, the first support plate 20 is provided with a third adjustment component 60 which is mirrored with the first adjustment component 40, and the second support plate 30 is provided with a fourth adjustment component 70 which is mirrored with the second adjustment component 50. The first adjustment component 40 is also mirrored with the second adjustment component 50 and the fourth adjustment component 70, and the second adjustment component 50 is also mirrored with the third adjustment component 60.
[0043] In this embodiment, the first adjustment component 40 and the third adjustment component 60 are mirror images of the first support plate 20 along its longitudinal centerline, and both the first adjustment component 40 and the third adjustment component 60 form a 45° angle with the longitudinal centerline of the first support plate 20; the second adjustment component 50 and the fourth adjustment component 70 are mirror images of the second support plate 30 along its longitudinal centerline, and both the second adjustment component 50 and the fourth adjustment component 70 form a 45° angle with the longitudinal centerline of the second support plate 30; at the same time, since the first support plate 20 and the second support plate 30 are also mirror images, any two adjacent adjustment components among the first adjustment component 40, the second adjustment component 50, the third adjustment component 60, and the fourth adjustment component 70 are also mirror images.
[0044] Thus, by setting the first adjustment component 40, the second adjustment component 50, the third adjustment component 60, and the fourth adjustment component 70, the distance between the first adjustment component 40, the second adjustment component 50, the third adjustment component 60, and the fourth adjustment component 70, that is, the distance between the tiger's mouth 33 (described in detail later), can be adjusted according to the size of the workpiece being processed, so as to achieve clamping of workpieces of different sizes.
[0045] The first adjustment component 40, the second adjustment component 50, the third adjustment component 60, and the fourth adjustment component 70 all include a slide groove 31 and a slider 32 disposed on the slide groove 31. In this embodiment, the slider 32 is T-shaped, and the vertical part of the T-shaped slider 32 is slidably connected to the slide groove 31, so that the slider 32 can reciprocate within the slide groove 31.
[0046] The front end of the slider 32 is provided with a tiger's mouth 33. In this embodiment, the tiger's mouth 33 is square, so that it can clamp the square workpiece.
[0047] In one embodiment, the tiger's mouth 33 is arc-shaped, thereby enabling the clamping of a circular workpiece.
[0048] The rear end of the slider 32 is provided with a fixing block 34 that is fixedly connected to the slide groove 31. In this embodiment, the fixing block 34 is T-shaped, and the vertical part of the T-shaped fixing block 34 is fixedly connected to the slide groove 31, thereby the fixing block 34 restricts the sliding space of the slider 32 in the slide groove 31.
[0049] The fixing block 34 is provided with a transverse threaded hole 35. In this embodiment, the transverse threaded hole 35 is provided in the transverse part of the T-shaped fixing block 34 and passes through the transverse part of the T-shaped fixing block 34.
[0050] A transverse screw 36 is provided in the transverse threaded hole 35. The transverse screw 36 passes through the transverse threaded hole 35 and contacts the rear end of the slider 32. By controlling the rotation of the transverse screw 36, the slider 32 can slide in the slide groove 31 and drive the jaw 33 to clamp the workpiece.
[0051] Thus, by rotating the transverse screw 36 within the transverse threaded hole 35, the slider 32 is controlled to slide back and forth within the slide groove 31. In turn, the rotation of the transverse screw 36 within the transverse threaded hole 35 is adjusted according to the different sizes of the workpieces to achieve clamping of workpieces of different sizes.

In this embodiment, the slider 32 is T-shaped, and the vertical part of the T-shaped slider 32 is slidably connected to the slide groove 31, so that the slider 32 can slide back and forth in the slide groove 31.
[0066] The front end of the slider 32 is provided with a tiger's mouth 33. In this embodiment, the tiger's mouth 33 is square, so that it can clamp the square workpiece.
[0067] In one embodiment, the tiger's mouth 33 is arc-shaped, thereby enabling the clamping of a circular workpiece.
[0068] The rear end of the slider 32 is provided with a fixing block 34 that is fixedly connected to the slide groove 31. In this embodiment, the fixing block 34 is T-shaped, and the vertical part of the T-shaped fixing block 34 is fixedly connected to the slide groove 31, thereby the fixing block 34 restricts the sliding space of the slider 32 in the slide groove 31.
