The cutting component 2 includes a motor 201, a rotating shaft 202, a rotating disk 203, a round pin 204, a movable ring 205, a cutting rod 206, a cutting knife 207 and an inclined plate 208. The housing 1 is provided with a motor 201, a rotating shaft 202 is provided on the motor 201, a rotating disk 203 is provided on the rotating shaft 202, a round pin 204 is provided on the rotating disk 203, a movable ring 205 is movably provided on the round pin 204, and a movable ring 205 is movably provided on the movable ring A cutting rod 206 is installed on 205, and a cutting knife 207 is installed on the cutting rod 206. An inclined plate 208 is installed on the shell 1. When in use, the part of the straw to be cut is placed on the cutting hole 209, and the rotation of the motor 201 can drive the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 will drive the rotating disk 203 to rotate. The rotation of the rotating disk 203 will drive the round pin 204 to move. The movement of the round pin 204 will drive the movable ring 205 to move up and down. When the movable ring 205 moves downward, it will drive the cutting rod 206 downward and cut the straw through the cutting knife 207.

[0026] Further, see Figure 1 A cutting hole 209 is provided on the inclined plate 208, and a limiting block 2010 is installed on the round pin 204. The setting of the cutting hole 209 can facilitate the cutting of the cutting knife 207, and the cutting knife 207 will not be directly in contact with the inclined plate 208 to damage the blade surface.

[0027] Further, see Figure 2A guide sleeve 2011 is installed on the housing 1, and the cutting rod 206 is slidably installed in the guide sleeve 2011. Through the setting of the guide sleeve 2011, the movement of the cutting rod 206 can be guided so that the cutting rod 206 can only move up and down.

[0028] Further, see Figure 1 A collection box 2012 is provided at the bottom of the shell 1, and a handle is installed on the collection box 2012. The straws cut by the cutting knife 207 will fall into the collection box 2012 for collection.

The setting of the cushion 304 can increase the friction during contact and reduce the damage to the straw caused by clamping, thereby preventing the straw from tilting on the inclined plate 208 and affecting the length and accuracy of the straw cutting.

[0032] Further, see Figure 4 A T-shaped slot 305 is provided on the inclined plate 208, and a T-shaped slider 306 is installed at the bottom of the positioning block 303. The T-shaped slider 306 is slidably installed in the T-shaped slot 305. The T-shaped slider 306 slides in the T-shaped slot 305 to limit the movement of the positioning block 303, so that the positioning block 303 can only slide on the inclined plate 208.

[0033] Further, see Figure 4 A support block 307 is installed on the inclined plate 208, and the second positioning screw 302 is rotatably installed in the support block 307. Through the setting of the support block 307, a supporting effect can be played on the second positioning screw 302.

[0034] Further, see Figure 4A knob is installed at one end of the first positioning screw 301, and a plurality of rotary blocks are installed on the knob. Turning the knob can drive the first positioning screw 301 and the second positioning screw 302 to rotate, thereby facilitating the rotation of the first positioning screw 301 and the second positioning screw 302.

[0035] Working principle of the utility model: All electrical equipment of the utility model is connected to an external power supply. When in use, the part of the straw to be cut is placed on the cutting hole 209, the motor 201 rotates to drive the rotating shaft 202 to rotate, the rotating shaft 202 rotates to drive the rotating disk 203 to rotate, the rotating disk 203 rotates to drive the round pin 204 to move, the round pin 204 moves to drive the movable ring 205 to move up and down, and the movable ring 205 moves downward to drive the cutting rod 206 downward and cut the straw through the cutting knife 207, and the straw cut by the cutting knife 207 will fall on the receiving The straws are collected in the collecting box 2012, and the collecting box 2012 can be pulled out by the handle to process the straws in the collecting box 2012. The first positioning screw 301 and the second positioning screw 302 are rotated and the two positioning blocks 303 are driven to move on the outer walls of the first positioning screw 301 and the second positioning screw 302 respectively and approach each other to clamp and fix the straws. The setting of the soft pad 304 can enhance the friction during contact and reduce the damage to the straws caused by clamping, thereby preventing the straws from tilting on the inclined plate 208 and affecting the length and accuracy of the straw cutting.
