[0022] like Figures 1 to 4 As shown, a precision guide rail transmission device for a PS line cutting machine according to the first aspect of this utility model includes a base 1 and fixed rods 2 fixedly connected to both sides of the top surface of the base 1. A circular slide 3 is provided on the opposite side of the two fixed rods 2. A guide rail groove 4 capable of accommodating PS lines is opened on the surface of the circular slide 3. A fitting structure 5 is provided on both sides of the surface of the circular slide 3. A cutting structure 6 is provided on both sides of the top surface of the guide rail groove 4. The PS lines driven inside the guide rail groove 4 can be cut by contacting the fitting structure 5.

[0023] The technical effects achieved by the above embodiments are as follows: This utility model utilizes the opened guide groove 4 to allow the PS line to be located therein. The transmission motor 10 drives the transmission rod 502 to rotate, causing the circular slide 3 to rotate circumferentially to transmit the PS line. At the same time, the two T-shaped blocks 602 that rotate one revolution will use the sliding effect of the slide groove 603 and the pulley 504 to generate compression, causing the two cutting blades 604 on the opposite side of the two T-shaped blocks 602 to produce a relative cutting effect. This avoids the inability of most devices to produce a cutting effect when performing precision transmission. While the device stably guides the transmission work, it also adds a cutting effect, thereby improving the use effect of the device.

The two connecting rods 503 are fixedly connected to the top surfaces of the two connecting blocks 501. The two pulleys 504 are rotatably connected to one side of the rod wall of the two connecting rods 503.

[0026] The technical effect achieved by the above embodiment is as follows: when the transmission motor 10 drives the transmission rod 502 to rotate, the circular slide 3 will be driven to rotate by the transmission rod 502. At this time, the guide groove 4 opened on the surface of the circular slide 3 will follow the rotation of the circular slide 3 and perform guiding transmission work.

[0029] The technical effect achieved by the above embodiment is as follows: When the circular slide 3 rotates, it will contact the pulley 504 via the T-shaped block 602 rotatably connected to the top surface of the guide rail groove 4. At the same time, the T-shaped block 602 will fit with the pulley 504 via the groove 603, thereby causing the two T-shaped blocks 602 to compress the spring 606, causing the two T-shaped blocks 602 to move relative to each other. The two cutting blades 604 will then fit together to produce a cutting effect, thereby cutting the PS lines driven inside the guide rail groove 4. When the cutting is completed, the two T-shaped blocks 602 will reset again via the spring 606, waiting for the next cutting operation.
