[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] Please see Figures 1-2This utility model provides a technical solution comprising: a workbench 1, a pair of slide rails 2 fixedly connected to the upper surface of the workbench 1, a positioning block 22 disposed between the two slide rails 2, the positioning block 22 being fixedly installed on the upper surface of the workbench 1, the positioning block 22 having a certain degree of magnetism, a positioning device 3 disposed on the upper surface of the two slide rails 2, the positioning device 3 being used to fix gears, the positioning device 3 including a slide plate 9, a positioning plate 7, and a fixing nail 8, the slide plate 9 being able to slide on the slide rails 2 and being attracted by the positioning block 22, the movement of the slide plate 9 being pushed by a handle 5, the upper surface of the slide plate 9 having multiple positioning holes 6 for fixing the positioning plate 7, the multiple positioning plates 7 being disposed on the upper surface of the slide plate 9, each positioning plate 7 having a second groove 12, the second groove 12 being the setting of which allows the positioning plate 7 to be flexibly placed, the fixing nail 8 penetrating through. The second slide 12 extends into the positioning hole 6 and is threadedly connected to it. The positioning plate 7 can slide and rotate back and forth around the fixing nail 8. A pair of waste ports 10 are provided on the upper surface of the slide plate 9. The waste ports 10 can be used to clean up the waste left after drilling. A waste trough 11 is provided between the two waste ports 10. The waste trough 11 is used to store the waste left after drilling. A fixing platform 13 is fixedly installed in the middle part of the waste trough 11. A central column 14 is fixedly connected to the upper surface of the fixing platform 13. The central column 14 is used to sleeve the gear. A retaining ring 16 is fixedly sleeved on the top of the central column 14. The retaining ring 16 is used to block the rotating cylinder 17 to ensure that the rotating cylinder 17 can rotate and will not deviate, so as to ensure that the gear can rotate easily after placement. The rotating cylinder 17 is sleeved on the central column 14. A threaded hole 15 is provided on the top of the central column 14. The threaded hole 15 is used to install the pressure cap 18.

[0022] First, remove all the positioning plates 7 and the pressure cap 18. Then, attach the gear to the rotating cylinder 17. Next, select a suitable positioning plate 7 and fix it in the appropriate position using the fixing nail 8. The gear needs to be firmly fixed. Finally, install the pressure cap 18 and rotate it to press the gear. After the positioning device 3 fixes the gear, it can be pushed onto the positioning block 22 by the handle 5. Then, the magnetic attraction of the positioning block 22 will make it difficult to move. At this time, drilling can be performed. Waste can enter the waste port 10 from the waste trough 11 for cleaning.

[0023] Example 2

[0024] Please see Figures 2-4Based on Embodiment 1, a pressure cap 18 is provided on the top of the central column 14. The pressure cap 18 is used to further press the gear and make it difficult for it to rotate. A rubber ring 19 is fixedly connected to the bottom of the pressure cap 18. The rubber ring 19 is provided to increase friction. A groove 20 is provided at the bottom of the pressure cap 18. The groove 20 is large enough to accommodate the rotating cylinder 17. A threaded column 21 is fixedly connected in the groove 20. The threaded column 21 is provided with threads. The threaded column 21 extends into the threaded hole 15 and is threadedly connected to it. When the threaded column 21 rotates, it can drive the entire pressure cap 18 to move up and down to fix the gear.

[0025] The pressure cap 18 is used to further fix the gear. By setting a rubber ring 19 on the lower surface of the pressure cap 18, the friction coefficient is increased so that it will not easily rotate during drilling, thus making the drilling process safer and more reliable.

[0026] Example 3

[0027] Please see Figure 2 Based on Embodiment 2, the bottom of the slide plate 9 is provided with two first sliding grooves 4, and the two first sliding grooves 4 and two sliding tracks 2 are correspondingly arranged. The two sliding tracks 2 extend into the two first sliding grooves 4 respectively and are slidably connected to them. A handle 5 is fixedly connected to one side of the slide plate 9, and the handle 5 can push the entire slide plate 9 to slide.

[0028] In actual use, first remove all the positioning plates 7, remove the pressure cap 18, and then attach the gear to the rotating cylinder 17. Then, select a suitable positioning plate 7 and fix it in the appropriate position with the fixing nail 8. The gear needs to be firmly fixed. Finally, install the pressure cap 18 and rotate the pressure cap 18 to press the gear. After the positioning device 3 fixes the gear, it can be pushed onto the positioning block 22 by the handle 5. Then, the magnetic adsorption of the positioning block 22 makes it difficult to move. At this time, drilling can be performed. The waste material can enter the waste port 10 from the waste trough 11 for cleaning. The pressure cap 18 is for further fixing the gear. By setting a rubber ring 19 on the lower surface of the pressure cap 18, the friction coefficient is increased so that it will not easily rotate during drilling, thus making the drilling process safer and more reliable.
