[0025] The following specifically describes the specific settings and functions of its auxiliary structure 2.

[0026] Referring to Figures 2 to 4As shown in the figure, in this embodiment: The auxiliary structure 2 includes a fixed column 222, the fixed column 222 is fixedly connected to the connecting column 1, the inner wall of the fixed column 222 is provided with an engagement groove 202, four auxiliary grooves 201, an auxiliary hole 206, eight connecting grooves 203, four connecting holes 205 and four limiting grooves 217. The engagement groove 202, the auxiliary groove 201, the auxiliary hole 206, the connecting groove 203, the connecting hole 205 and the limiting groove 217 communicate with each other. A gear 207 is rotatably connected to the bottom wall of the engagement groove 202. The upper end of the gear 207 is fixedly connected to an auxiliary column 208, and the auxiliary column 208 is rotatably connected to the auxiliary hole 206. A toothed ring 212 is rotatably connected to the bottom wall of the auxiliary groove 201. A lead screw 213 is threadedly connected to the inner wall of the toothed ring 212. The lead screw 213 is slidably connected to the connecting hole 205. Two connecting blocks 214 are fixedly connected to the arc surface of the lead screw 213. On one side of the two connecting blocks 214 away from the lead screw 213, a top plate 215 is fixedly connected. The top plate 215 is slidably connected to the connecting groove 203. A top block 218 is slidably connected to the inner wall of the chute 204. An installation groove 219 is provided in the inner wall of the top block 218. A spring 221 is provided between the side of the top block 218 away from the cutter tooth 3 and the chute 204. The two ends of the spring 221 are fixedly connected to the top block 218 and the chute 204 respectively. The installation groove 219 is slidably connected to the top plate 215. The four toothed rings 212 are engaged with the gear 207. By setting the auxiliary structure 2, when a person needs to install the cutter teeth 3, the person can first slide the four cutter teeth 3 into the inner wall of the limiting groove 217, and then rotate the auxiliary column 208 to move the two top blocks 218 in the direction close to the cutter teeth 3 until the cutter teeth 3 are squeezed and fixed. Thus, it is convenient for the person to fix the four cutter teeth 3 simultaneously, and the working efficiency of the person is improved. An expansion rod 220 is fixedly connected to the inner wall of the chute 204. The output end of the expansion rod 220 is fixedly connected to the top block 218. The expansion rod 220 can limit the top block 218, and can prevent the top block 218 from being misaligned when sliding in the inner wall of the chute 204. A positioning column 216 is fixedly connected to the upper end of the lead screw 213. The positioning column 216 is slidably connected to the connecting hole 205 and the cutter tooth 3. The positioning column 216 can limit the cutter tooth 3 and can increase the stability of the cutter tooth 3. A connecting rod 209 is fixedly connected to the upper end of the auxiliary column 208. A rotating rod 210 is fixedly connected to the inner wall of the connecting rod 209. The connecting rod 209 and the rotating rod 210 can facilitate the person to rotate the auxiliary column 208 and can improve the operation convenience of the person. Two anti-slip sleeves 211 are fixedly connected to the arc surface of the rotating rod 210. The cross section of the anti-slip sleeve 211 is a hollow circle. The anti-slip sleeve 211 can increase the friction between the person's hand and the rotating rod 210, and can prevent the person from slipping when rotating the rotating rod 210. The top block 218 is made of stainless steel. The stainless steel material has greater strength and better wear resistance, and is not easily worn out significantly during short-term use.

[0027] Working principle: When a person needs to use a cutting tool to cut a metal part, the person first installs the cutting teeth 3 on the fixed column 222, then installs the fixed column 222 on the tool rest in the numerical control machine tool, and then manipulates the numerical control machine tool to cut the metal part. When the person needs to install the cutting teeth 3, the person can first place the four cutting teeth 3 into the four limiting grooves 217 respectively. During the process of sliding into the limiting grooves 217, the positioning column 216 will slide into the inner wall of the cutting teeth 3. The positioning column 216 can limit the cutting teeth 3 and increase the stability of the cutting teeth 3. After the cutting teeth 3 are moved to the inner wall of the limiting grooves 217, the person drives the rotating rod 210 to rotate with the help of the protective sleeve. The anti-slip sleeve 211 can increase the friction between the person's hand and the rotating rod 210 and prevent the person from slipping when rotating the rotating rod 210. Then the rotating rod 210 drives the connecting rod 209 to rotate, and the connecting rod 209 drives the auxiliary column 208 to rotate. The connecting rod 209 and the rotating rod 210 can facilitate the person to rotate the auxiliary column 208 and improve the operation convenience of the person. Then the auxiliary column 208 drives the gear 207 to rotate, the gear 207 drives the four tooth rings 212 to rotate, the tooth rings 212 drive the lead screw 213 to move upward, the lead screw 213 drives the two connecting blocks 214 and the positioning column 216 to move upward, the two connecting blocks 214 respectively drive the top plate 215 to move upward, and the top plate 215 slides on the inner walls of the connecting groove 203 and the installation groove 219. During the process of moving upward, the top plate 215 will abut against the side wall of the installation groove 219, and then drive the top block 218 to move towards the cutting teeth 3. The top block 218 drives the output end of the telescopic rod 220 to move towards the cutting teeth 3. The telescopic rod 220 can limit the top block 218 and prevent the top block 218 from being misaligned when sliding on the inner wall of the sliding groove 204. The top block 218 also drives the spring 221 to be stretched until the two top blocks 218 abut against the cutting teeth 3. When the top block 218 contacts the cutting teeth 3, the cutting teeth 3 will contact the inclined surface of the top block 218 and generate a forward and downward force on the cutting teeth 3, thereby achieving the effect of fixing the cutting teeth 3. The top block 218 is made of stainless steel, and the stainless steel material has greater strength and better wear resistance, and is not easily worn significantly during short-term use.
