The cutting shape and size of the cutting machine can be adjusted according to needs, making it suitable for materials of various shapes and sizes.

[0003] In the prior art, during the process of cutting materials, friction will occur between the cutter and the material, resulting in gradual wear of the cutter. As the use time increases, the sharpness and precision of the cutter will gradually decrease, thus affecting the cutting quality and efficiency. Therefore, when the cutting effect is affected due to wear of the cutting cutter, it is necessary to disassemble and replace the cutting cutter. However, when replacing the cutting cutter on the cutting machine in the prior art, it is necessary to first remove the cutter by rotating the bolt with a tool, and then install and reset the cutter with a tool. The disassembly and assembly operations are relatively cumbersome, which not only brings inconvenience to the disassembly and replacement of the cutting cutter, but also reduces the work efficiency. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a cutting machine which is convenient for disassembling and assembling a cutter, and can effectively solve the problems in the background technique.

The outer side of the rack 20 is fixedly connected with a side plate 22, and the outer side wall of the side plate 22 is fixedly connected with a connecting plate 23.

[0021] As Figure 2 shown, a set of left and right symmetric plug rods 10 are fixedly installed on the top surface of the cutting tool 8, and connecting holes 11 are opened on the side walls of the plug rods 10. After inserting the plug rods 10 into the slots 12, the cutting tool 8 can be positioned and installed on the bottom surface of the tool mounting seat 6, and the opened connecting holes 11 are used to cooperate with the use of the connecting plate 23.

[0022] As Figure 3As shown in the figure, a set of left - and right - symmetric slots 12 corresponding to the inserting rods 10 are opened on the bottom surface of the tool mounting seat 6, and the inserting rods 10 are inserted and mounted in the slots 12. Inserting the inserting rods 10 into the slots 12 can realize the positioning and installation of the cutting tool 8;

[0023] As Figure 3 shown, an inner cavity 13 is opened inside the tool mounting seat 6 and between the left - and right - symmetric slots 12. Side holes 14 communicating with the slots 12 are respectively opened on the left and right inner side walls of the inner cavity 13. T - shaped sliding grooves 15 are respectively opened on the left and right sides of the top surface inside the inner cavity 13, and rotating holes 16 are respectively opened on the front and rear inner side walls of the inner cavity 13. Through the side holes 14 provided in the inner cavity 13, the connecting plate 23 can move in and out of the slots 12. The provided T - shaped sliding grooves 15 can enable the T - shaped sliding bars 21 to perform sliding operations, and the provided rotating holes 16 can enable the rotating rods 18 to perform rotating operations;

[0024] As Figure 3 shown, rotating rods 18 are respectively fixedly installed on the front and rear sides of the gear 17, and the rotating rods 18 are movably installed in the rotating holes 16. A knob 19 is also fixedly installed on the front wall of the front - end rotating rod 18. Manually rotating the knob 19 can drive the rotating rod 18 to rotate in the rotating hole 16, and the rotating rod 18 will drive the gear 17 to rotate inside the inner cavity 13;

[0025] As Figure 3 shown, T - shaped sliding bars 21 are respectively fixedly installed on the opposite side walls of the two racks 20, and the T - shaped sliding bars 21 are movably installed in the T - shaped sliding grooves 15. The two racks 20 are respectively engaged with the left side of the top and the right side of the bottom of the gear 17. A side plate 22 is fixedly installed on the outer end of the rack 20. A connecting plate 23 is fixedly installed on the outer side wall of the side plate 22, and the connecting plate 23 passes through the side hole 14 and is inserted and installed in the connecting hole 11. After the gear 17 rotates, under the meshing action, it will drive the side plates 22 at the top and bottom to move in opposite directions. The T - shaped sliding bars 21 slide in the T - shaped sliding grooves 15, and the racks 20 will push the side plates 22 to move outward until the connecting plate 23 installed on the outer side wall of the side plate 22 passes through the side hole 14 and is inserted into the connecting hole 11 opened on the side wall of the inserting rod 10 in the slot 12, so that the cutting tool 8 can be quickly installed and fixed on the bottom surface of the tool mounting seat 6 for use.
