[0022] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0023] Reference Figure 1-4 The utility model provides an embodiment of a metal cutting tool that is easy to disassemble, including a handle 1, a cutter disc 7 is fixedly connected to the bottom of the handle 1, a plurality of mounting grooves 10 are provided inside the cutter disc 7, a cutter body 6 is correspondingly arranged inside the mounting groove 10, the mounting groove 10 can correspond to the cutter body 6, and the mounting groove 10 is triangular in design, which can effectively prevent the cutter body 6 from falling off, and the two ends of the cutter body 6 are fixedly connected to the limiting blocks 13;

[0024] Limiting grooves 11 are provided at both ends of the installation groove 10, and the limiting blocks 13 correspond to the limiting grooves 11. The corresponding between the limiting blocks 13 and the limiting grooves 11 enables the cutter body 6 to quickly enter the interior of the installation groove 10, thereby realizing the rapid positioning of the cutter body 6. The limiting blocks 13 are provided with screw holes 12, which can correspond to the positioning bolts 8, thereby realizing the function of thread locking.

[0025] A fixed plate 2 is fixedly connected to the handle 1, and a cylinder 3 is fixedly connected to the four ends below the fixed plate 2. A movable plate 5 is fixedly connected to the extended end of the cylinder 3. When replacing and installing it, the limit blocks 13 at both ends of the cutter body 6 are matched with the limit grooves 11, and then the cylinder 3 at the upper end is started to drive the movable plate 5 to move downward, so that the movable plate 5 limits the downward pressure of the cutter body 6, and then the positioning bolt 8 is screwed into the screw hole 12 to achieve double limit locking of the cutter body 6, ensuring the stability of the cutter body 6 when in use. The entire metal cutting tool is easy to disassemble and replace, and has high strength, which can improve the cutting efficiency;

[0026] A plurality of slide grooves 9 are provided on the outside of the handle 1, and a slider 4 is fixedly connected to the inside of the movable plate 5. The slider 4 is slidably connected to the inside of the slide groove 9. By providing the slide groove 9 and the slider 4, the stability of the movable plate 5 during movement can be ensured, and its strength when pressed down can be improved;

[0027] The movable plate 5 is threadedly connected with a plurality of positioning bolts 8 , which correspond to the screw holes 12 . The positioning bolts 8 can be used to double-lock the cutter body 6 to ensure its stability during use.

[0028] Working principle: When the device is in use and the cutter body 6 needs to be disassembled and replaced, first tighten the positioning bolt 8 so that the positioning bolt 8 withdraws from the inside of the screw hole 12, and then start the upper cylinder 3 to drive the movable plate 5 to rise, thereby releasing the restricting force on the cutter body 6. The staff can directly take the cutter body 6 out of the inside of the installation groove 10. When replacing and installing it, the limit blocks 13 at both ends of the cutter body 6 are matched with the limit grooves 11, and then start the upper cylinder 3 to drive the movable plate 5 to move downward, so that the movable plate 5 restricts the downward pressure on the cutter body 6, and then tighten the positioning bolt 8 and the screw hole 12 for threaded connection, so as to realize double limit locking of the cutter body 6 and ensure the stability of the cutter body 6 during use. The entire metal cutting tool is easy to disassemble and replace, and has high strength, which can improve the cutting efficiency.
