The second plastic block 2 is fixedly installed on the side of the first plastic block 1. An arc-shaped groove 3 is opened on the first plastic block 1. An arc-shaped cutter 4 is movably connected to the middle of the arc-shaped groove 3. A slider 5 is fixedly installed on the top of the arc-shaped cutter 4. The slider 5 is movably connected to the arc-shaped groove 3. A rectangular box 6 is fixedly installed on the top of the slider 5. A clamping groove 7 is opened in the middle of the rectangular box 6. A clamping block 8 is movably connected to the middle of the clamping groove 7. A placement hole 9 is opened on the side of the clamping block 8. One end of a spring 10 is fixedly connected to the end face of the placement hole 9 on the clamping block 8. The other end of the spring 10 is fixedly connected to a buckle 11. An installation hole 12 is opened on the side of the rectangular box 6. The clamping groove 7 communicates with the installation hole 12. A first hydraulic rod 13 is fixedly connected to the side of the clamping block 8. A second hydraulic rod 14 is movably connected to the outside of the first hydraulic rod 13. A hydraulic device 15 is fixedly installed on the side of the second hydraulic rod 14; wherein, due to the material characteristics of the first plastic block 1 and the second plastic block 2 and their relatively large proportion in the overall device, it provides a guarantee for the light weight of the overall device; the opening of the arc-shaped groove 3 provides a guarantee for the installation of the arc-shaped cutter 4; the cooperation between the slider 5 and the arc-shaped groove 3 can further limit the sliding of the arc-shaped cutter 4; the opening of the rectangular box 6 provides a guarantee for the opening of the clamping groove 7 and the installation hole 12; the opening of the clamping groove 7 provides a guarantee for the connection of the clamping block 8 to the rectangular box 6; the opening of the placement hole 9 provides space for the installation of the spring 10 and also provides space for the telescopic movement of the spring 10 and the buckle 11; the installation hole 12 is used to connect the buckle 11; the setting of the hydraulic device 15 provides kinetic energy for the telescopic movement of the first hydraulic rod 13 at the second hydraulic rod 14, and thus provides a guarantee for the movement and punching of the arc-shaped cutter 4.

[0023] The length of the arc-shaped cutter 4 is less than the depth of the arc-shaped groove 3; the size settings of the above components can ensure that the arc-shaped cutter 4 is completely placed in the arc-shaped groove 3 when not in use, avoiding damage to other people, and thus improving the safety of the device during use.

[0024] The length of the spring 10 when not deformed is equal to the depth of the placement hole 9; the size settings of the above components can ensure the smooth sliding of the buckle 11 in the placement hole 9, avoiding the spring 10 protruding from the clamping block 8 and causing misalignment sliding of the buckle 11.

[0025] The length of the buckle 11 is greater than the thickness of the side wall of the rectangular box 6, and the front end of the buckle 11 is arc-shaped; the size settings of the above components can ensure that the buckle 11 protrudes from the rectangular box 6 after connection, facilitating the operator to press the buckle 11, and thus facilitating subsequent disassembly; the shape setting of the buckle 11 can ensure the quick disassembly of the buckle 11.

[0026] The rear part of the second plastic block 2 is fixedly installed with a U-shaped grip 16, and four finger grooves 17 are opened on the U-shaped grip 16; the arrangement of the four finger grooves 17 on the U-shaped grip 16 facilitates the operator to firmly hold the hand, so that the phenomenon of the operator's hand slipping off can be avoided during the cutting process, further improving the safety of the device.

[0027] Working principle: According to Figures 1-5 , an operator holds the U-shaped grip 16 with one hand, puts four fingers into the four finger grooves 17, supports the bottom of the first plastic block 1 with the other hand, then aligns the arc-shaped cutter 4 with the extruded strip. At this time, the whole device is placed on the car seat, then the supporting hand is removed, and the hydraulic device 15 is opened. At this time, the first hydraulic rod 13 moves forward along the second hydraulic rod 14, and then drives the clamping block 8 and the rectangular box 6 to move forward, and then drives the arc-shaped cutter 4 to move forward along the arc-shaped groove 3. The arc-shaped cutter 4 cuts the extruded strip, and then the hydraulic device 15 is closed. When the arc-shaped cutter 4 needs to be replaced, press the two ends of the buckle 11, and the spring 10 deforms under force. At this time, the buckle 11 moves along the placement hole 9. When the arc section of the buckle 11 moves to the inside of the installation hole 12, pull the arc-shaped cutter 4 outwards, and the arc-shaped cutter 4 can be taken out from the arc-shaped groove 3. Then repeat the above process in reverse, and the replacement of the arc-shaped cutter 4 can be realized. The above is the working process of the whole device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
