[0016] In order to make the purpose, technical scheme and advantage of the application more clear, the technical scheme in the embodiment will be clearly and completely described below in combination with the drawings in the embodiment, however, the following specific embodiment and embodiment are only for the purpose of illustration, and are not limited to the utility model.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0019] To solve the above technical problems, such as Figures 1-4 As shown, this utility model designs a quick-release structure for a cutting device, including a handle 1 and a mounting base 2. The bottom end of the handle 1 is provided with a cutting edge. The handle 1 is disposed in the mounting base 2, which is used to connect with the displacement drive mechanism of the cutting device. It also includes a limiting rod 4 and a positioning block 5. The handle 1 is inserted into the bottom insertion hole of the mounting base 2 and connected to the positioning block 5. The limiting rod 4 passes through the through hole of the mounting base 2 laterally. The limiting rod 4 has a vertically penetrating sliding groove 6 and a limiting recess 7. The limiting rod 4 can move laterally so that the handle 1 can switch between a fixed state and an adjustable state. In the fixed state, the positioning block 5 is locked in place with the limiting recess 7 of the limiting rod 4. In the adjustable state, the positioning block 5 slides in place with the sliding groove 6 of the limiting rod 4. This quick-release structure design for the cutting device greatly simplifies the disassembly and installation process of the cutting tool. The whole process does not require complicated tools, the operation is simple and quick, greatly shortens the tool replacement time, and improves work efficiency.

[0020] In this embodiment, it is further preferred to include a first spring 8. The limiting rod 4 is a rectangular block. The through hole of the mounting base 2 is adapted to the shape of the limiting rod 4. A baffle 9 is provided at each of the left and right ends of the limiting rod 4. The diameter of the baffle 9 is greater than the maximum width of the through hole. The first spring 8 is arranged laterally. The first spring 8 is sleeved on the outside of the limiting rod 4 and located between the baffle 9 and the side of the mounting base 2. The precise fit between the rectangular limiting rod 4 and the through hole of the mounting base 2 ensures accurate lateral movement trajectory. The preload of the first spring 8 keeps the limiting rod 4 in the locked position under normal conditions. When the operator needs to disassemble and replace the tool, the limiting rod 4 is pulled out laterally, and the spring stores energy. After releasing the hand, the spring pushes the limiting rod 4 to reset.

[0021] Further preferably in the embodiment, the left and right ends of the limiting rod 4 are respectively provided with threaded holes, and a bolt 10 is arranged in each threaded hole, the bolt 10 being used for fixing the baffle 9 to the outer side of the limiting rod 4, the bolt 10 being connected to realize the detachable design of the baffle 9, the spacing between the baffle 9 and the mounting seat 2 can be finely adjusted by adjusting the screwing depth of the bolt 10, so as to control the pre-compression amount of the first spring 8, and in addition, the modular design allows quick replacement of the worn spring.

[0022] Further preferably in the embodiment, the inner side of the mounting seat 2 is further provided with a screw rod 11 which is movable up and down, the head of the screw rod 11 is located below and in contact with the upper surface of the tool shank 1, the top of the mounting seat 2 is provided with a nut 12, the screw rod 11 is in threaded cooperation with the nut 12, and the outer side of the screw rod 11 is further sleeved with a second spring 13, the second spring 13 being used for positioning the tool shank 1 by pressing the tool shank 1 through the screw rod 11 so that the positioning block 5 is clamped in the limiting groove 7.

[0023] In specific work, when the tool is in a fixed state and does not need to be switched, the second spring 13 is in a pre-compressed state, the head of the screw rod 11 continuously presses the upper surface of the tool shank 1, forcing the positioning block 5 to tightly engage with the limiting groove 7 of the limiting rod 4, when the tool needs to be switched, the operator needs to manually lift the tool shank 1 upward, at this time, the tool shank 1 drives the positioning block 5 to vertically move upward and disengage from the locking area of the limiting groove 7, in this process, the second spring 13 is further compressed due to the upward movement of the tool shank 1, the spring resistance increases, but the lifting force artificially applied needs to overcome the resistance to realize the separation, at this time, the limiting rod 4 can be manually moved transversely, only needs to align the positioning block 5 with the position of the sliding groove 6 of the limiting rod 4, at this time, the tool shank 1 enters an adjustable state and can freely take out the tool, when the tool is installed, only needs to insert the tool shank 1 so that the positioning block 5 can realize the automatic clamping of the tool shank 1 through the sliding groove 6 under the driving of the first spring 8 and the second spring 13 in sequence, and the locking action is automatically completed through the spring force of the two.

[0024] Further preferably in the embodiment, the front side of the tool shank 1 is provided with a recess 3, and the positioning block 5 is arranged in the recess 3 of the tool shank 1 in a key groove cooperation manner, the key groove cooperation manner makes the positioning block 5 convenient to disassemble and replace, facilitating the later maintenance.
