[0032] Reference Appendix Figure 3-8 The adjusting mechanism 7 includes a bracket 701, a through hole 702, a bottom hole 703, a second U-shaped hole 704, a support screw 705, a bottom rod 706, a round hole 707, and a limiting nut 708. The bottom ends of the two brackets 701 are provided with through holes 702, and the bottom ends of the through holes 702 are provided with bottom holes 703. The bottom ends of the two brackets 701 are also provided with two symmetrically distributed second U-shaped holes 704.

[0033] The bracket 701 is U-shaped. The length of one side wall of the bracket 701 is greater than the length of the other side wall. The diameter of the through hole 702 is greater than the diameter of the support screw 705. The width of the bottom hole 703 is greater than the width of the bottom rod 706. The width of the bottom hole 703 is less than the radius of the through hole 702. The bottom rod 706 can be inserted into the bottom groove 603. The limiting screw hole 604, the slot 605 and the round hole 707 can be aligned synchronously. The support rod 606 can be inserted into the second U-shaped hole 704. A second threaded groove is opened in the middle of the side wall of the support screw 705. The diameter of the second threaded groove is greater than the diameter of both ends of the support screw 705. The diameter of the round hole 707 and the diameter of the slot 605 are both smaller than the limiting screw hole 604. The diameter of the first threaded groove is greater than the bottom diameter of the limiting screw 607.
[0034] First, pass the support screw 705 and the bottom rod 706 through the through hole 702 and the bottom hole 703 respectively, so that the bracket 701 moves into the second threaded groove. Then, screw the limiting nut 708 into the second threaded groove from both ends of the support screw 705. At this time, insert both ends of the support screw 705 into the first U-shaped hole 602, and align the round hole 707 with the limiting screw hole 604 and the slot 605, and insert the bottom rod 706 into the bottom groove 603 (as shown in the attached diagram). Figure 5 At this point, one end of the limiting screw 607 is passed through the limiting screw hole 604 and into the round hole 707. Then, the limiting screw 607 is threadedly connected to the limiting screw hole 604 to push the bottom of the limiting screw 607 through the round hole 707 and into the slot 605, thereby fixing the support screw 705. The limiting screw 607 can be unscrewed to remove it, achieving the effect of convenient disassembly and installation.
[0035] At the same time, the support screw 705 drives the second U-shaped hole 704 to lock onto the support rod 606, so that the support rod 606 provides support for the bracket 701. Then, the bracket 701 is moved left and right, thereby driving the clamping mechanism 8 to move, so as to achieve the position adjustment effect of the clamping plate 804. Then, the two limit nuts 708 are screwed toward the bracket 701 to clamp the bracket 701, so that the bracket 701 and the support screw 705 are connected as one unit.
[0036] Reference Appendix Figure 4-7 The clamping mechanism 8 includes a connecting block 801, a support screw hole 802, a clamping screw 803, and a clamping plate 804. The top of the bracket 701 is connected to the connecting block 801, and two connecting blocks 801 are connected to the top of the bracket 701. The side wall of the connecting block 801 is provided with a support screw hole 802, and the side wall of the support screw hole 802 is threadedly connected to the clamping screw 803. One end of the clamping screw 803 is connected to the clamping plate 804. The clamping plate 804 can be shaped like a disc, and the clamping screw 803 can be composed of two screws.
[0037] When the bracket 701 moves left and right, it drives the connecting block 801 to move left and right, which in turn drives the clamping screw 803 to move left and right, thereby realizing the left and right position adjustment of the clamping plate 804. Rotating the clamping screw 803 can drive the clamping plate 804 to move back and forth, so that the two clamping plates 804 can clamp the parts, realizing the effect of adjusting the distance between the clamping plates 804. The adjustment of the bracket 1 is a large distance adjustment, while the adjustment of the clamping plate 804 is a small distance adjustment.
