[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0024] Reference Figure 1-4This is the first embodiment of the present invention, which provides a high-strength tap, including: a mounting rod 1 and a cutting edge 2. The cutting edge 2 is fixedly connected to the lower surface of the mounting rod 1. A pair of arc-shaped protective sleeves 3 are slidably connected to the outside of the mounting rod 1. A pair of T-shaped notches 4 are provided on the rod body of the mounting rod 1. A rotating device 5 is provided through the arc surface of the pair of arc-shaped protective sleeves 3. An arc-shaped plate 6 is provided on the lower surface of each arc-shaped protective sleeve 3, and several equally spaced mating blocks are provided on the upper surface of each arc-shaped plate 6. A mating groove is provided on the bottom surface of each arc-shaped protective sleeve 3, and the mating groove is T-shaped. A pair of opposing thrust springs are provided inside the mating groove. A positioning block is provided at the opposite end of the pair of thrust springs, and the diameter of the positioning block is smaller than the hole provided on the mating block.

[0025] The rotating device 5 includes a rectangular sleeve 7 and a circular sleeve 8. The same circular sleeve 8 penetrates one of the two short vertical surfaces of the rectangular sleeve 7, and the circular sleeve 8 and the rectangular sleeve 7 are rotatably connected. The circular sleeve 8 is rotatably connected to the circular rod 9.

[0026] A torsion bar 10 is fixedly connected to the circular surface of the round rod 9 away from the rectangular sleeve 7. An L-shaped guide rod 11 is provided on the rod body of the round rod 9 between the torsion bar 10 and the circular sleeve 8. The L-shaped guide rod 11 is fixedly connected to the round rod 9. A disc 12 is fixedly connected to the vertical surface of the rectangular sleeve 7 near the L-shaped guide rod 11. An arc-shaped notch is opened through the circular surface of the disc 12. The outer diameter of the L-shaped guide rod 11 away from the torsion bar 10 is the same as the diameter of the gap left by the arc-shaped notch.

[0027] The circular ring sleeve 8 is fixedly connected to the T-shaped slider 13 at the circular surface away from the L-shaped guide rod 11, and a pair of mounting grooves are provided on the vertical surface of the T-shaped slider 13, and several rollers 14 with the same spacing are provided inside the mounting grooves.

[0028] A baffle 15 is provided on the circular surface of the round rod 9 inside the circular ring 8. A stop block is fixedly connected to the arc surface inside the circular ring 8. A memory spring 16 is provided on the circular surface of the baffle 15 away from the round rod 9. One end of the memory spring 16 is connected to the circular surface of the baffle 15, and the other end of the memory spring 16 is connected to the stop block. A guide rod 17 is also provided on the circular surface of the baffle 15, and the end of the guide rod 17 away from the baffle 15 passes through the stop block. The guide rod 17 and the stop block are in a sliding relationship. A pair of rectangular blocks 18 are also provided on the circular surface of the baffle 15. A pair of storage sleeves 19 are also provided on the arc surface inside the circular ring 8, and the cross-sectional size of the storage sleeve 19 is the same as the cross-sectional size of the rectangular block 18.

[0029] In use, first fix the mounting rod 1 to the equipment to be installed, then push the torsion rod 10. Because the torsion rod 10 is connected to the round rod 9, and one end of the round rod 9 is inside the annular sleeve 8, the round rod 9 and the annular sleeve 8 are in a sliding relationship. Because a baffle 15 is provided on the circular surface of the round rod 9 inside the annular sleeve 8, and a stop block is fixedly connected to the arc surface inside the annular sleeve 8, a memory spring 16 is provided on the circular surface of the baffle 15 away from the round rod 9. One end of the memory spring 16 is connected to the circular surface of the baffle 15, and the other end of the memory spring 16 is connected to... Next, a guide rod 17 is provided on the circular surface of the baffle 15, and the end of the guide rod 17 away from the baffle 15 passes through the baffle. The guide rod 17 and the baffle are in a sliding relationship. So as the external force pushes in, the rectangular block 18 will slowly insert into the inside of the storage sleeve 19. At this time, the body of the L-shaped guide rod 11 will also pass through the arc-shaped notch on the circular surface of the disc 12 and then rotate. At this time, the rotation of the torsion rod 10 will also drive the T-shaped slider 13 to rotate. After the rotation is completed, the arc-shaped protective sleeve 3 and the arc-shaped plate 6 can be removed. Example

[0030] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: several rubber sheets 20 are provided at the inner ring of the arc plate 6, several arc-shaped mounting plates 21 with the same spacing are provided at the inner ring of each pair of arc plates 6, an arc-shaped loading strip 22 is installed at the inner ring of the arc-shaped mounting plate 21, and a soft brush is provided at the arc surface of the arc-shaped loading strip 22. A fiber cotton layer 23 is provided directly above the rubber sheet 20.

[0031] When using the tap, after installing the tap, there is no need to twist the torsion bar 10. First, hold the pair of arc-shaped protective sleeves 3 and then move them up and down manually. As the arc-shaped protective sleeves 3 move, the arc-shaped loading strip 22 is installed on the inner ring of the arc-shaped mounting plate 21, and the arc surface of the arc-shaped loading strip 22 is equipped with a soft brush. As the soft brush moves up and down continuously, the iron filings on the tap cutting edge can be cleaned out. Also, because there is a fiber cotton layer 23 directly above the rubber sheet 20, static electricity will be generated during the continuous friction between the fiber cotton layer 23 and the tap, thereby attracting small impurities.

[0032] The remaining structure is the same as that in Example 1.
