[0027] like Figure 1-4As shown, this utility model discloses a quick-release and disassembly structure for a cutting tool, including a housing 20. The housing 20 is provided with an upper cutting tool assembly 10 and a lower cutting tool assembly 21. The upper cutting tool assembly 10 includes a fixed cylinder 12, a movable cylinder 11, and an upper cutting tool holder 13 for mounting the upper cutting tool 131. The fixed cylinder 12 is sleeved on the outside of the upper cutting tool holder 13, and the movable cylinder 11 is sleeved on the outside of the fixed cylinder 12. An elastic element 14 is provided between the movable cylinder 11 and the fixed cylinder 12 to maintain the upward movement tendency of the movable cylinder 11. The upper end of the movable cylinder 11 presses against the housing 20. A plurality of limiting members 15 are provided to fix the upper tool holder 13. The fixed cylinder 12 has a limiting hole 122 corresponding to the limiting member 15. The movable cylinder 11 has a first clearance groove 114. In normal state, the movable cylinder 11 presses against the limiting member 15 so that it extends along the limiting hole 122 and presses against the side wall of the upper tool holder 13. When the movable cylinder 11 is pressed down, the limiting member 15 is directly facing the first clearance groove 114. Through the cooperation of the movable cylinder 11, the fixed cylinder 12, the elastic member 14 and the limiting member 15, pressing the movable cylinder 11 can quickly remove the upper tool holder 13 for cleaning, solving the problem of time-consuming, labor-intensive and inconvenient use.

[0028] In this invention, the upper blade assembly 10 is disposed on the lower blade assembly 21.

[0029] The first clearance groove 114 has an inclined surface 115 on its lower side that slopes upward from top to bottom towards the tool holder 13; by setting the inclined surface 115, the limiting member 15 can be pushed into the limiting hole 122 more effectively.

[0030] The limiting member 15 is spherical, and the diameter of the limiting member 15 is greater than the thickness of the side wall of the fixed cylinder 12. By setting the diameter of the limiting member 15 to be greater than the thickness of the side wall of the fixed cylinder 12, the limiting member 15 can extend out of the limiting hole 122 under the pressure of the movable cylinder 11 and press against the upper tool holder 13 to limit the upper tool holder 13.

[0031] It should be understood that the limiting member 15 can also be a pin with spherical surfaces at both ends.

[0032] The upper tool holder 13 has a limiting groove 134 on the outer side wall of the corresponding limiting member 15; by setting the limiting groove 134, the upper tool holder 13 can be better fixed in conjunction with the limiting member 15.

[0033] The first clearance groove 114 penetrates the upper end face of the movable cylinder 11. The fixed cylinder 12 is provided with a first blocking block 121 that protrudes radially outward from the periphery of the blocking and limiting member 15. During assembly, the first blocking block 121 is located in the first clearance groove 114. By setting the first blocking block 121, on the one hand, the limiting member 15 can be blocked in the first clearance groove 114 to prevent it from falling out, and on the other hand, the movable cylinder 11 can be limited to prevent it from rotating.

[0034] The upper end of the movable cylinder 11 is provided with a radially outward protruding edge 111, and a first step 112 is formed between the protruding edge 111 and the upper end face of the movable cylinder 11; the housing 20 is provided with a mounting hole corresponding to the first step 112, and the first step 112 presses against the inner side of the mounting hole; by setting the first step 112, the movable cylinder 11 can press against the housing 20 more stably.

[0035] The lower circumference of the fixed cylinder 12 forms a second clearance groove 124. When the movable cylinder 11 is pressed down, the lower end of the movable cylinder 11 moves toward the second clearance groove 124. A reinforcing rib 125 is provided in the second clearance groove 124. The movable cylinder 11 is provided with a third clearance groove 116 corresponding to the reinforcing rib 125. One end of the elastic member 14 abuts against the reinforcing rib 125, and the other end abuts against the lower surface of the protrusion 111. The upper circumference of the fixed cylinder 12 is provided with a guide protrusion 126 extending along the axial direction of the reinforcing rib 125. A guide groove 117 corresponding to the guide protrusion 126 is opened on the inner side of the movable cylinder 11. The reinforcing rib 125 and the protrusion 111 can limit the elastic member 14 and improve the structural stability. The cooperation of the reinforcing rib 125 and the third clearance groove 116, the guide protrusion 126 and the guide groove 117 can limit the movable cylinder 11, making the up-and-down movement of the movable cylinder 11 more stable.

[0036] The inner wall of the movable cylinder 11 is provided with a second step 113 facing downwards, and the outer wall of the fixed cylinder 12 is provided with a third step 123 facing upwards. When the movable cylinder 11 is pressed down to the lowest position, the second step 113 presses against the third step 123. The cooperation between the second step 113 and the third step 123 can prevent the pressing force from being too large, which would exceed the elastic limit of the elastic element 14 and cause damage to the elastic element 14, thereby improving the service life of the elastic element 14.

[0037] The upper blade holder 13 has a handle 132; the upper blade holder 13 is provided with a second blocking block 133 to prevent the handle 132 from rotating downward; by providing the handle 132, the upper blade holder 13 can be easily lifted, and by providing the second blocking block 133, the handle 132 can be lifted up, so that part of the handle 132 is suspended in the air, making it easier to pick up.

[0038] The method of using this utility model is as follows: Press the movable cylinder 11 to release the fixing of the limiting member 15 to the upper knife holder 13, then take out the upper knife holder 13 through the handle 132, release the pressure on the movable cylinder 11, and clean the upper knife 131; after cleaning, press the movable cylinder 11 to put the upper knife holder 13 back, and then release the pressure on the movable cylinder 11 to complete the installation.

[0039] This utility model uses a limiting member 15 between the movable cylinder 11 and the fixed cylinder 12, and uses an elastic member 14 to keep the movable cylinder 11 moving upward. Pressing the movable cylinder 11 will cause the limiting member 15 to engage and lock the upper tool holder 13, which can realize the quick disassembly of the upper tool holder 13, making it convenient and quick to use.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
