[0036] Example 1

[0037] Please see Figures 1-2 This embodiment provides a file for repairing mechanical parts to improve the convenience of storage and carrying.

[0038] In this embodiment, the file for repairing mechanical parts includes a handle 10, a blade 20, a button 30, a pin 40, and a transmission rod 50. The blade 20 is inserted into a groove 11 at the top of the handle 10. A mounting groove 12 is provided on the outside of the groove 11, and a mounting cylinder 13 communicating with the groove 11 is provided at the bottom of the mounting groove 12. The pin 40 is inserted into the mounting cylinder 13, and the transmission rod 50 passes through the pin 40. The transmission rod 50 can move relative to the pin 40. The transmission rod 50 is slidably arranged in an inclined direction. Both ends of the transmission rod 50 extend out of the mounting cylinder 13 and have parallel inclined surfaces 51. The button 30 is slidably inserted into the mounting groove 12. The knob 30 is sleeved on the outside of the mounting cylinder 13. A guide block 32 that fits against the inclined surface 51 is provided on the inner wall of the button 30. A compression spring 33 is provided between the pin 40 and the button 30. Under the pushing force of the compression spring 33, the pin 40 is inserted into the positioning hole 21 on the cutter body 20.

[0039] In this embodiment, by pressing the button 30 to push the transmission rod 50 to slide radially along the pin 40, the pin 40 moves outward and disengages from the positioning hole 21, thereby releasing the pin 40 from the restriction on the blade body 20, allowing the blade body 20 to be removed from the handle 10 for easy replacement of different models of blade bodies. The detachable compatibility of a handle 10 with different models of blade bodies 20 improves the convenience of storage and carrying.

[0040] It should be noted that the mounting groove 12 is generally arranged outside the insertion groove 11, and the axis of the mounting groove 12 is perpendicular to the extension direction of the insertion groove 11. The mounting cylinder 13 is formed at the bottom of the mounting groove 12 and is arranged coaxially with the mounting groove 12. The mounting cylinder 13 is connected to the insertion groove 11, so that the pin 40 can extend into the insertion groove 11. An annular retaining edge 14 is provided at the port of the mounting groove 12, and the inner diameter of the retaining edge 14 is smaller than the diameter of the mounting groove 12. The retaining edge 14 is arranged coaxially with the mounting groove 12. The retaining edge 14 and the retaining ring 31 on the button 30 play a blocking role, thereby restricting the button 30 inside the mounting groove 12 and preventing the button 30 from falling out of the mounting groove 12.

[0041] Furthermore, the pin 40 is constructed in a cylindrical shape and is slidably inserted into the mounting sleeve 13. The pin 40 can move into the insertion groove 11 and be inserted into the positioning hole 21 on the blade body 20, thereby restricting the blade body 20 to the handle 10, forming a detachable connection between the blade body 20 and the handle 10. An assembly groove is provided on the pin 40, which is inclined relative to the axis of the pin 40 and intersects with the axis of the pin 40. The transmission rod 50 is slidably inserted into the aforementioned assembly groove, allowing the transmission rod 50 to... The entire assembly is inclined relative to the pin 40. A movable groove 15 is provided on the side wall of the mounting cylinder 13 along its diameter direction. That is, the movable groove 15 is arranged perpendicular to the pin 40. The two ends of the transmission rod 50 extend to the outside of the mounting cylinder 13 through the movable groove 15. The transmission rod 50 moves inside the movable groove 15. That is, the movement direction of the transmission rod 50 is perpendicular to the axis of the pin 40. The two ends of the transmission rod 50 are provided with inclined surfaces 51 that are parallel to each other. The inclined surfaces 51 are arranged inclined to the axis of the pin 40.

[0042] In addition, the button 30 is inserted into the mounting groove 12. A retaining ring 31 corresponding to the retaining edge 14 is provided on the outside of the button 30. The baffle 31 is arranged on the inside of the retaining edge 14 to prevent the button 30 from moving out of the mounting groove 12. The button 30 is sleeved on the outside of the mounting cylinder 13. The guide block 32 is formed on the inner wall of the button 30, and the guide block 32 is arranged in a one-to-one correspondence with the inclined surfaces 51 at both ends of the transmission rod 50. The guide block 32 fits against the inclined surfaces 51. A slot 41 for engaging the compression spring 33 is provided at the end of the pin 40. One end of the compression spring 41 is fixed to the bottom of the slot 41, and the other end is fixed to the inside of the button 30. The compression spring 33, the knob 30, and the pin 40 are arranged coaxially.

[0043] It should be noted that, in the initial state, under the elastic thrust of the compression spring 33, the button 30 extends out of the handle 10, and the retaining ring 31 on the button 30 abuts against the retaining edge 14 at the port of the mounting groove 12. The pin 40 extends into the insertion groove 11 and is inserted into the positioning hole 21 on the blade body 20. The blade body 20 is locked on the handle 10 by the pin 40. At this time, the distance that the upper end of the transmission rod 50 extends out of the mounting cylinder 13 is greater than the distance that its lower end extends out of the mounting cylinder 13.

[0044] When disassembling the blade body 20, pressing the button 30 further compresses the compression spring 33. With the cooperation of the guide block 32 and the inclined surface 51, the transmission rod 50 slides downward along the movable groove 15. At the same time, the transmission rod 50 pushes the pin 40 to move outward until the pin 40 disengages from the positioning hole 21. At this time, the pin 40 releases the restriction of the blade body 20 on the handle 10, and the blade body 20 can be pulled out from the insertion groove 11.

[0045] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
