[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, the cutting teeth sequentially and intermittently remove the excess material from the workpiece. Milling cutters are mainly used on milling machines to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.
[0003] Publication number CN210848362U mentions a metal cutting tool that is easy to assemble and disassemble. Through the design of a linkage, slider, handle, screw, and screw hole, only one screw is used for fixed installation. Assembly and disassembly are achieved by tightening and loosening the screw, resulting in short assembly and disassembly time and strong fixation, saving significant manpower and time, and making it easier for users. However, when the milling cutter needs to be replaced, the mounting base must be removed first, making the replacement process more cumbersome and affecting the efficiency of cutting tool assembly and disassembly. There is an urgent need for a cutting tool that is easy to assemble and disassemble to solve the aforementioned problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool that is easy to install and disassemble, comprising a milling cutter mounting holder, a milling cutter body slidably connected within the milling cutter mounting holder, a rectangular locating head fixedly connected to the upper end of the milling cutter body, two locating slots formed on the circumferential surface of the milling cutter body, and two screw holes formed on the circumferential surface of the milling cutter mounting holder.
[0006] The milling cutter mounting holder is equipped with disassembly and assembly components at both its left and right ends. One set of disassembly and assembly components includes a sliding rod, a fixed connecting plate, a limiting ring, a spring, a docking sleeve, a fixing pad, and a positioning block. The sliding rod is slidably connected inside the milling cutter mounting holder. The fixed connecting plate is fixedly connected to the left end of the sliding rod. The limiting ring is fixedly connected to the circumferential surface of the sliding rod. The spring is slidably connected to the circumferential surface of the sliding rod. The docking sleeve is fixedly connected to the right end of the sliding rod. The fixing pad is fixedly connected to the right end of the docking sleeve. The positioning block is fixedly connected to the right end of the fixing pad.
[0007] Furthermore, the circumferential surface of the milling cutter mounting holder is provided with two protective rounded corners.
[0008] Furthermore, the two positioning blocks respectively cooperate with the two positioning slots.
[0009] Furthermore, both of the aforementioned retaining pads are made of rubber material.
[0010] Furthermore, a rubber layer is provided between the fixed connecting plate and the milling cutter mounting holder.
[0011] Furthermore, the through holes on the surfaces of the two fixed connecting plates are respectively aligned with the four screw holes.
[0012] The beneficial effects of this utility model are as follows: This utility model provides a cutting tool that is easy to install and disassemble. Because this utility model adds a sliding rod, a fixed connecting plate, a limiting retaining ring, a spring, a docking sleeve, a fixed sleeve gasket, and a positioning block, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. Through two sets of disassembly and assembly components, the milling cutter body can be installed in the milling cutter mounting holder at the same time, while the docking sleeve and the fixed connecting plate effectively limit the position of the screw, avoiding the situation where the thread is fixedly connected to the milling cutter mounting holder and it is difficult to remove.

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figures 1-5 This utility model provides a technical solution: a cutting tool that is easy to install and disassemble, including a milling cutter mounting holder 1, a milling cutter body 2 slidably connected inside the milling cutter mounting holder 1, a rectangular positioning head 9 fixedly connected to the upper end of the milling cutter body 2, two positioning slots 10 formed on the circumferential surface of the milling cutter body 2, two screw holes 8 formed on the circumferential surface of the milling cutter mounting holder 1, and disassembly and assembly components provided at both the left and right ends of the milling cutter mounting holder 1, one set of disassembly and assembly components including a sliding rod 13, a fixed connecting plate 7, a limiting retaining ring 5, a spring 6, a docking sleeve 4, a fixed sleeve 11, and a positioning block 12. The sliding rod 13 is slidably connected to the milling cutter mounting holder 1. The fixed connecting plate 7 is fixedly connected to the left end of the sliding rod 13. The limiting ring 5 is fixedly connected to the circumferential surface of the sliding rod 13. The spring 6 is slidably connected to the circumferential surface of the sliding rod 13. The docking sleeve 4 is fixedly connected to the right end of the sliding rod 13. The fixing sleeve 11 is fixedly connected to the right end of the docking sleeve 4. The positioning block 12 is fixedly connected to the right end of the fixing sleeve 11. This design solves the problem in the original device that when the milling cutter needs to be replaced, the mounting holder must be removed first, which is more troublesome during the replacement process and thus affects the efficiency of cutting tool installation and disassembly.
[0022] As the first embodiment of this utility model: Two protective rounded corners 3 are provided on the circumferential surface of the milling cutter mounting holder 1. These protective rounded corners 3 on the surface of the milling cutter mounting holder 1 prevent scratches to the user's hands from the edges of the rounded grooves on the surface of the milling cutter mounting holder 1. Two positioning blocks 12 respectively cooperate with two positioning slots 10. When it is necessary to fix the milling cutter body 2 inside the milling cutter mounting holder 1, the fixing connecting plate 7 is fixed in the groove on the surface of the milling cutter mounting holder 1 with screws, so that the positioning blocks 12 lock into the positioning slots 10, thereby fixing the milling cutter body 2 inside the milling cutter mounting holder 1. Two fixing gaskets 11 are made of rubber material, which increases the connection strength between the two mating sleeves 4 and the milling cutter body 2, and protects the surface of the milling cutter body 2. A rubber layer is provided between the fixing connecting plate 7 and the milling cutter mounting holder 1, which reduces friction between the fixing connecting plate 7 and the milling cutter mounting holder 1, increasing the service life of the milling cutter mounting holder 1 and the fixing connecting plate 7. The through holes on the surfaces of the two fixed connecting plates 7 are respectively aligned with the four screw holes 8. When it is necessary to install the milling cutter body 2 in the milling cutter mounting holder 1, it can be fixed to the surface of the milling cutter mounting holder 1 by passing screws through the fixed connecting plates 7.
[0023] As a second embodiment of this utility model: When it is necessary to replace the milling cutter body 2, the screws connecting the milling cutter body 2 and the milling cutter mounting holder 1 should be removed first with a screwdriver. Then, the mating sleeve 4 moves outward under the pushing force of the spring 6, so that the positioning block 12 releases the positioning slot 10. Then, the user removes the milling cutter body 2, slides the milling cutter body 2 to be replaced into the milling cutter mounting holder 1, installs the fixing connecting plate 7 so that the positioning block 12 at its end is locked in the positioning slot 10, and then fixes the fixing connecting plate 7 in the groove on the surface of the milling cutter mounting holder 1 with screws, so that the milling cutter mounting holder 1 and the milling cutter body 2 can be fixedly connected.
