Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of a power head for a Swiss-type lathe, comprising a Swiss-type lathe body 1, a power head housing 2 inserted into the inner wall of the Swiss-type lathe body 1, the power head housing 2 mainly connecting the power head body 4 (this is prior art and will not be described in detail here), a T-shaped block 3 fixedly connected to the top of the power head housing 2, the power head body 4 disposed in the middle of the power head housing 2, a connecting plate 6 elastically connected to the inner wall of the right end of the Swiss-type lathe body 1 via a return spring 5, the connecting plate 6 mainly connecting the moving tube 7 and the positioning plate 8 and the return spring 5, the moving tube 7 being fixedly connected through and through the middle of the connecting plate 6, allowing the connecting plate 6 and the moving tube 7 to move laterally along the inner wall of the Swiss-type lathe body 1, and a positioning plate 8 fixedly connected to the left end of the connecting plate 6, the positioning plate 8 being inclined, which, when compressed, causes the positioning plate 8 to move laterally (see reference). Figure 4 The inner wall of the moving tube 7 is provided with a positioning mechanism, and the bottom inner wall of the T-shaped block 3 is provided with a slot 12.

[0033] Reference Figure 2 and Figure 5 The bottom of the Swiss-type machine body 1 is fixedly connected to a support frame 13, and the top of the support frame 13 is fixedly connected to a bellows 14. The bellows 14 contains corresponding electronic components that enable the bellows 14 to drive the fan 15. The fan 15 is installed on the inner wall of the bellows 14. The fan 15 generates airflow through the bellows 14 to dissipate heat from the power head housing 2, ensuring the stability of the power head body 4. The inner wall of the Swiss-type machine body 1 has a conical groove 16. The conical groove 16 is wider at the bottom and narrower at the top. The area of ​​the conical groove 16 decreases from bottom to top, the flow rate increases, and the pressure decreases accordingly, improving its heat dissipation effect. The inner wall of the Swiss-type machine body 1 has ventilation holes 17, which allow the heat generated by the power head housing 2 to be discharged outward through the ventilation holes 17. The Swiss-type machine body 1 has a cavity connected to the ventilation holes 17.

[0034] Reference Figures 1-3 The inner wall of the right end of the Swiss-type machine body 1 is fixedly connected to one end of the return spring 5. When the connecting plate 6 moves to the right, it will compress the return spring 5. When resetting, the elastic force of the return spring 5 will carry the connecting plate 6 to reset. The other end of the return spring 5 is fixedly connected to the outer wall of the right end of the connecting plate 6. The connecting plate 6 is slidably connected to the inner wall of the Swiss-type machine body 1. The moving tube 7 passes through and is slidably connected to the inner wall of the Swiss-type machine body 1. The Swiss-type machine body 1 has slots corresponding to the connecting plate 6 and the moving tube 7, which allow the connecting plate 6 and the moving tube 7 to slide along the slots. The positioning plate 8 and the moving tube 7 are respectively inserted into the inner wall of the T-shaped block 3. The T-shaped block 3 has slots corresponding to the positioning plate 8 and the moving tube 7. The T-shaped block 3 is inserted into the inner wall of the Swiss-type machine body 1. The Swiss-type machine body 1 has slots corresponding to the T-shaped block 3, allowing the T-shaped block 3 to be inserted into the slots to initially position the power head housing 2.

[0035] Reference Figure 4 The positioning mechanism includes a pressing plate 10, with a protruding part at the right end. Pressing the protruding part causes the pressing plate 10 to move vertically along with the wedge 11. The pressing plate 10 is slidably connected to the inner wall of the moving tube 7. The top end of the pressing plate 10 is fixedly connected to the wedge 11, which is inclined. When the inclined surface is pressed, the wedge 11 moves along the inner wall of the moving tube 7. The inner wall of the bottom end of the pressing plate 10 is elastically connected to the moving tube 7 through a positioning spring 9. The bottom end of the pressing plate 10 is fixedly connected to one end of the positioning spring 9. When the pressing plate 10 moves downward, it compresses the positioning spring 9. When resetting, the elastic force of the positioning spring 9 is used to reset the pressing plate 10. The other end of the positioning spring 9 is fixedly connected to the inner wall of the top end of the moving tube 7. The wedge 11 is inserted into the inner wall of the slot 12.

[0036] Working principle: First, when the power head housing 2 needs to be removed from the Swiss Army machine body 1, simply press the protruding part of the pressing plate 10 to move the pressing plate 10 downward with the wedge block 11 and compress the positioning spring 9, so that the wedge block 11 and the slot of the slot 12 are separated. Then, pull the moving tube 7 to move the connecting plate 6 and the positioning plate 8 to the right and compress the return spring 5, so that the moving tube 7 and the positioning plate 8 are separated from the slot on the T-block 3. Then, move the power head housing 2 and the T-block 3 and the power head body 4 out of the Swiss Army machine body 1. Finally, release the moving tube 7 and use the reverse elastic force of the return spring 5 to move the connecting plate 6, the moving tube 7 and the positioning plate 8 to the left to reset.

[0037] When installing the power head housing 2 and the Swiss-type machine body 1, simply insert the power head housing 2 and the T-block 3 into the Swiss-type machine body 1. Use the T-block 3 to connect with the Swiss-type machine body 1 to initially position the entire power head housing 2. Press the pressing plate 10 in advance to retract the wedge 11 into the moving tube 7. At this time, let the right end of the power head housing 2 press against the inclined surface of the positioning plate 8, so that the positioning plate 8, along with the moving tube 7 and the connecting plate 6, moves to the right and compresses the return spring 5. After compression, release the pressing plate 10 to expose the wedge 11 in the moving tube 7. When the positioning plate 8 and the moving tube 7 coincide with the groove of the T-block 3... Then, the reverse elastic force of the return spring 5 is used to move the connecting plate 6, the moving tube 7 and the positioning plate 8 to the right to reset. Since the elastic force of the return spring 5 is greater than that of the positioning spring 9, the outer wall of the T-block 3 will press the inclined surface of the wedge block 11, causing the wedge block 11 to move downward with the pressing plate 10 and compress the positioning spring 9. When the positioning plate 8 and the moving tube 7 are inserted into the slot of the T-block 3, the slot 12 will coincide with the wedge block 11. The reverse elastic force of the positioning spring 9 is used to reset the pressing plate 10 and the wedge block 11, allowing the wedge block 11 to be inserted into the inner wall of the slot 12, which further improves the connection stability of the entire T-block 3.

[0038] During the use of the entire Swiss-type machine body 1, power head housing 2, and power head body 4, heat is discharged from the cavity of the Swiss-type machine body 1 through the ventilation hole 17. At the same time, the fan 15 in the air box 14 is started, and the air force is pressured through the conical groove 16, increasing the air flow rate and improving the heat dissipation effect.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
