[0032] It can be seen from the above structure that: by setting up the driving component, the connecting tube 20, the clamping roller 18 and the push rod 19 for use in conjunction, the clamping roller 18 can clamp the product when cutting the product. At this time, when cutting the product again, due to the clamping of the clamping roller 18, the cut product will not fall off at will, thereby avoiding the problem that the product has a large kinetic energy just after cutting and is easily damaged by falling directly.

[0033] Furthermore, the driving assembly includes a box body 21 connected to the connecting pipe 20, and the inner wall of the box body 21 is slidably connected with a pressure plate 22, the upper surface of the pressure plate 22 is fixedly connected with a pressure rod 23, and one end of the pressure rod 23 passes through the box body 21 and extends to the top of the box body 21, and one end of the pressure rod 23 located above the box body 21 is fixedly connected with a pedal 24, and the outer wall of the connecting pipe 20 is connected with a conduit 25, and one end of the conduit 25 is connected with the annular tube 12; by arranging the box body 21, the pressure plate 22 and the pressure rod 23 for use, the pedal 24 can be stepped on to drive the storage sleeve 11 to move, and the clamping roller 18 can also be driven to clamp the product, and both driving the storage sleeve 11 and driving the clamping roller 18 only requires stepping on the pedal 24, which is convenient and quick. When in use, the pressure generated by stepping on the pedal 24 is different to control the movement of the storage sleeve 11 or control the clamping roller 18 to clamp the product.

[0034] Furthermore, an annular groove is provided on the inner wall of the storage sleeve 11, and a rubber ring 26 is fixedly connected to the inner wall of the annular groove, a friction roller 27 is fixedly connected to one end of the clamping roller 18, and the friction roller 27 is arranged on one side of the rubber ring 26, and an air pipe 28 is connected to one side wall of the annular tube 12, and one end of the air pipe 28 is connected to the annular groove; by arranging the rubber ring 26 and the friction roller 27 for use together, after the product is cut off, when the air is continuously compressed through the pressure plate 22, when the force of the clamping roller 18 to clamp the product reaches a certain level, the continued compression of the air will cause the rubber ring 26 to expand, and the expanded rubber ring 26 will resist the friction roller 27, thereby quickly reducing the rotation speed of the product and the clamping roller 18, and quickly unloading the kinetic energy of the product.

[0035] Furthermore, a glass tube 29 is fixedly connected to the outer wall of the connecting sleeve 5, and the glass tube 29 is connected to the cavity 7. The outer wall of the glass tube 29 is marked with scale lines 30, and the inner wall of the glass tube 29 is slidably connected with a slider 31. By arranging the glass tube 29, the scale lines 30 and the slider 31 for use together, after the pressure in the cavity 7 reaches a certain level, the pressure in the cavity 7 will press the slider 31 to move. The pressure in the cavity 7 can be judged by the position of the slider 31, and then when the product is cut off, it can be judged by the slider 31 to avoid the pressure reaching the pressure that causes the rubber ring 26 to expand, and avoid affecting the rotation of the product and the clamping roller 18 when the product is cut off.

[0036] Furthermore, a rubber sleeve is provided on the outer wall of the pressing plate 22, and the outer wall of the rubber sleeve is interference fit with the inner wall of the box body 21; by providing the rubber sleeve, the air tightness of the pressing plate 22 can be increased.

[0037] Furthermore, a third spring 32 is provided on the outer wall of the pressure rod 23, and one end of the third spring 32 is against the pedal 24, and the other end of the third spring 32 is against the box body 21; by providing the third spring 32, when the stepped pedal 24 is released, the third spring 32 can push the pressure rod 23, the pressure plate 22 and the pedal 24 to reset.

[0038] Furthermore, a cushion 33 is fixedly connected to one end of the push rod 19; by providing the cushion 33, it is possible to prevent the push rod 19 from damaging the product when the push rod 19 pushes the product.

[0039] Furthermore, a receiving trough 34 is provided on the tool holder 3 on one side of the main shaft 2; by providing the receiving trough 34, the product pushed down by the push rod 19 can be received, and when in use, the receiving trough 34 can be filled with coolant, and the coolant can be used for buffering after the product falls into the receiving trough 34.

[0040] In the present invention, when the product is cut off, the pressing rod 23 and the pressing plate 22 are pressed down by stepping on the pedal 24, and the pressing plate 22 moves downward to compress the air in the box 21, so that the air enters the cavity 7 through the connecting pipe 20, and the air entering the cavity 7 compresses the first spring 10 and presses the first piston 8 and the first push rod 9, so that the first push rod 9 pushes the storage sleeve 11, so that the storage sleeve 11 moves to one side of the product and covers the product;

[0041] Continue to step on the pedal 24 to increase the pressure in the box 21. After the pressure in the box 21 increases to a certain level, air enters the annular tube 12 through the conduit 25. The air entering the annular tube 12 enters the sleeve 13. The air entering the sleeve 13 compresses the second spring 16 and presses the second piston 14. The moving second piston 14 drives the second push rod 15 and the housing 17 to move. The moving housing 17 drives the clamping roller 18 to move, so that the clamping roller 18 clamps the product. When the product is cut off at this time, due to the clamping of the clamping roller 18, the cut product will not fall off at will, thereby avoiding the problem that the product has a large kinetic energy just after being cut off and is easily damaged by falling directly.

[0042] After the product is cut, when the air is continuously compressed through the pressure plate 22, when the force of the clamping roller 18 to clamp the product reaches a certain level, the continued compression of the air will cause the rubber ring 26 to expand, and the expanded rubber ring 26 will abut against the friction roller 27, thereby quickly reducing the rotation speed of the product and the clamping roller 18. When the product stops rotating, the pedal 24 is released, and the expanded rubber ring 26 and the second spring 16 are reset. The reset second spring 16 pushes the clamping roller 18 to reset. After the clamping roller 18 is reset, the first spring 10 pushes the first piston 8 and the first push rod 9 to reset. The reset first push rod 9 drives the storage sleeve 11 to reset. After the storage sleeve 11 is reset to a certain position, the push rod 19 abuts against the product, so that the product falls into the receiving trough 34.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
