[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] See Figure 1-2 A speed reducer includes a housing 1, a motor 2, and a speed reduction assembly disposed within the housing 1. The speed reduction assembly includes a drive gear 3, a double-layer gear 4, a driven gear 5, and an outer roller cam 6. The motor 2 is fixed to the housing 1. The drive gear 3 is sleeved on the output shaft of the motor 2. The output shaft of the motor 2 extends into the housing 1 and engages the drive gear 3 with the large wheel of the double-layer gear 4. The small wheel of the double-layer gear 4 engages with the driven gear 5. The outer roller cam 6 includes a cam 7 and a driven disc 8. The driven disc 8 engages with the cam 7 through a needle roller bearing 9 on its surface. The driven gear 5 is sleeved on the cam 7.

[0025] In operation, motor 2 starts, driving drive gear 3 to rotate. Drive gear 3 drives double-layer gear 4 to rotate, double-layer gear 4 drives driven gear 5 to rotate, driven gear 5 drives cam 7 to rotate, and cam 7 drives driven disc 8 to rotate. Driven disc 8 is used to connect to turntable 10 to drive turntable 10 to rotate, and turntable 10 rotates to switch tools. The method of using drive gear 3, double-layer gear 4, and driven gear 5 to sequentially mesh and drive the outer roller cam 6 to rotate results in low wear and high precision.

[0026] In this embodiment, the output shaft of the motor 2 is fitted with a bearing 9. Both ends of the cam 7 are fitted with bearings 9. The driven disk 8 is fitted with a bearing 9. The motor 2, cam 7, and driven disk 8 are all rotatably connected to the housing 1 using bearings 9, ensuring smooth and stable rotation.

[0027] This utility model provides another technical solution: see [link] Figure 3-7 A disc tool magazine includes a speed reducer and a turntable 10, wherein the turntable 10 is connected to the driven disc 8, and the driven disc 8 drives the turntable 10 to rotate.

[0028] In this embodiment, a plurality of tool mounting parts 11 are evenly spaced on the outer edge of the turntable 10. The tool mounting parts 11 are used to assemble tool holders. Different tools are assembled one-to-one on each tool mounting part 11. The turntable 10 rotates to switch between different tools.

[0029] In this embodiment, the tool mounting component 11 includes a tool holder 12, a telescopic rod 13, a spring, and two hinges 14. The tool holder 12 is fixed on the turntable 10. The telescopic rod 13 is disposed in the through hole of the tool holder 12, and the spring is sleeved on the telescopic rod 13. The middle part of the hinge 14 is rotatably connected to the tool holder 12. The first ends of the two hinges 14 are respectively connected to the two ends of the telescopic rod 13, and the second ends are used to clamp the tool handle, making it easy to assemble and disassemble the tool handle. During assembly, the tool handle is pushed between the two hinges 14. The second ends of the two hinges 14 are pushed away from each other by the force of the tool handle. At this time, the first ends of the hinges 14 are brought closer to each other to compress the spring. After the tool handle is pushed between the second ends of the two hinges 14, the spring returns to its original position, thereby clamping the tool handle at the second ends of the two hinges 14, making it simple and convenient to assemble the tool handle. During disassembly, the tool handle is pulled outward. At this time, the tool handle opens the second ends of the two hinges 14, thereby pulling out the tool handle.

[0030] In this embodiment, the tool mounting component 11 further includes a plurality of rollers 15, which are rotatably connected one-to-one to the second end of the hinge 14. When the tool handle is pushed between the second ends of the two hinge 14 or pulled out between the second ends of the two hinge 14, the surface of the tool handle contacts the rollers 15, and the rollers 15 help to push or pull out the tool handle.

[0031] In this embodiment, bearings 9 are fitted at both ends of the cam 7, and the cam 7 is connected to the housing 1 through the bearings 9. When the cam 7 rotates, the cam 7, connected to the housing 1 by the bearings 9, can rotate relative to the housing 1.

[0032] In this embodiment, the present invention also includes a cover 16, which is used to cover the turntable 10 and serves both aesthetic and dustproof purposes.

[0033] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
