The rod body 1 is threadedly connected to the carrying ring 306. The outer wall of the cone 2 is provided with a discharge groove 4, and the inner wall of the discharge groove 4 is provided with an air-cooling hole 5. First, the rod body 1 and the cone 2 form a tap. By adjusting the carrying ring 306 and the pressing ring 307, the sliding rod 301 is adjusted and positioned along the sliding groove 308, so that the connecting rod 302 pushes the connecting block 303, and the fixed block 304 drives the crushing head 305 to pass through the cone 2. The crushing head 305 with a sharp structure can better resist and insert the material, avoiding the need for manual assistance or shaking during the processing, thereby affecting the processing accuracy. Example 2

[0024] In addition to all the technical features of Example 1, this embodiment also includes: a supporting mechanism 6 is provided on the outside of one end of the connecting rod 302, and support rods 601 are fixed on both sides of the outer wall of one end of the connecting rod 302 and the end of the support rod 601 away from the connecting rod 302 is connected to a support ring 602; when the connecting rod 302 is located inside the rod body 1, the support ring 602 fixed by the support rod 601 contacts the inside of the rod body 1, so as to prevent the crushing head 305 from shaking due to the force during processing, resulting in offset and affecting the processing accuracy. Example 3

[0025] In addition to all the technical features of the first embodiment, this embodiment also includes: a connecting end 7 is fixed to the bottom end of the cone 2, a sealing mechanism 8 is provided inside the connecting end 7, and the sealing mechanism 8 includes a sleeve ring 801, which is sleeved on the outside of the fixed block 304, and a sealing plate 802 is fixed to the outer wall of the sleeve ring 801, and the sleeve ring 801 is threadedly connected to the fixed block 304, and the sleeve ring 801 is tightly fitted with the connecting block 303; the outer wall of the connecting end 7 and the cone 2 have the same texture to play a transition effect, avoiding The cone 2 is directly connected to the crushing head 305 to avoid deviation or damage to the material. After processing, the load ring 306 and the pressing ring 307 are adjusted to allow the sliding rod 301 to drive the connecting rod 302, so that the connecting block 303 is separated from the cone 2, thereby allowing the waste material entering through the air-cooling hole 5 to be discharged. Then the ring 801 is threadedly connected to the fixed block 304, and then the sliding rod 301 is reset to allow the sealing plate 802 to penetrate the connecting end 7 and seal it flush, which is consistent with the structure of a conventional tap and has two usage methods.

[0026] Working principle: The rod body 1 and the cone 2 form a tap, pushing the sliding rod 301 to slide along the sliding groove 308, driving the connecting rod 302 to slide along the rod body 1, allowing the connecting block 303 to drive the fixed block 304, allowing the crushing head 305 to pass through the cone 2 and hit the material, and then rotating the carrying ring 306 and the pressing ring 307 to limit the sliding rod 301 so that the crushing head 305 can be fixed. After the crushing head 305 hits the material, it can be inserted into the material to avoid sliding and improve accuracy. The waste is discharged through the discharge groove 4 and the air is circulated through the air cooling hole 5 to dissipate heat. The sliding rod 301 is located on the rod body. 1, the support ring 602 fixed by the support rod 601 fits the inner wall of the rod body 1, stabilizing and preventing the crushing head 305 from shaking. The connecting end 7 fixed at the bottom of the cone 2 plays a connecting role, preventing direct contact with the tap that is too large to form or shake. When the hole is punched, the connecting block 303 is separated from the cone 2 by adjusting the carrying ring 306 to discharge the internal waste. After that, it is threadedly connected to the sleeve ring 801 through the fixing block 304, and then the sliding rod 301 is reset to allow the sealing plate 802 to seal the bottom of the connecting end 7, so that the tap is in a closed structure and is used in the same way as a conventional tap.
