The cam 6 is a three-dimensional protrusion composed of a semi-circle and an ellipse. The outer surface of the cam 6 is smooth and without sharp edges. The cam 6 has mounting and limiting holes for the rotating shaft 1. The long elliptical end of the cam 6 is used to eject the tool, and the semi-circular part is used to release the tool. When the long elliptical end of the cam 6 contacts the tool, the tool head extends, allowing for the tightening and loosening of fasteners.

[0057] like Figure 5 As shown, housing 4 is a cylindrical, irregularly shaped cavity housing with three tool slots, a large cylindrical hole 10, a small cylindrical hole 12, four threaded holes 13, and a hanging accessory mounting hole 11. The positions of the three tool slots are determined according to the shape of cam 6, ensuring that all tools can retract into housing 4 when not in use, preventing tool heads from scratching clothing. The small cylindrical hole 12 is used for mounting and limiting the bottom of rotating shaft 1; the hanging accessory mounting hole 11 is used for connecting portable tool hanging accessories to keychains.

[0058] The working principle of this invention is as follows: The user rotates the rotating disk 101 of the rotating shaft 1 at the bottom of the housing 4, which drives the cam 6 to rotate. When the long elliptical end of the cam 6 rotates to the tail of a tool, it pushes it outward, and the tool head extends out of the housing 4 for operation. After being released, it continues to rotate to the semi-circular position, and the spring 7 pulls the tool back into the housing 4, achieving automatic hiding. The three-station design supports the independent selection and use of three tools.

[0059] The advantages of this invention are: High safety: All tools are fully built-in, preventing scratches to clothing or skin.

[0060] Easy to use: simply rotate with one hand to switch tools, no additional unlocking required.

[0061] Reliable structure: modular design with fewer parts, making processing and assembly simple.

[0062] Portable and aesthetically pleasing: It is small in size, can be used as a keychain, and combines the functions of a tool and an ornament.

[0063] Low cost: The parts have a simple structure and are suitable for mass production.

[0064] Example 3: Based on embodiment 1 or 2, this embodiment provides a method for assembling a portable tool pendant, specifically: inserting the rotating shaft 1 into the center hole of the cam 6; Insert the component through the small cylindrical hole 12 at the bottom of the housing 4; Insert the spring 7 into the tail of each tool and place it into the corresponding tool slot; The tail of each tool contacts the outer contour of cam 6; Cover the cover plate 2, and screw the screw 9 through the countersunk hole 201 into the threaded hole 13 on the top of the housing 4 to complete the assembly; You can carry it with you by attaching a keychain or lanyard through the mounting hole 11.

[0065] In this invention, after the rotating shaft 1 and the cam 6 are engaged, they are inserted into the mounting hole (small cylindrical hole 12) at the bottom of the housing 4. After the spring 7 is put into each tool, it is placed in the tool slot on the housing 4. The cover plate 2 is fastened to the threaded hole 13 on the housing 4 with screws 9 to complete the entire assembly.

[0066] Example 4: Based on Embodiment 1 or 2, this embodiment provides a method for using a portable tool pendant, the specific steps of which are as follows: After assembling the portable tool pendant, when needed, rotating the rotating shaft 1 drives the cam 6 to rotate synchronously. When the long elliptical end of the cam 6 presses against the corresponding tool tail, the tool overcomes the elastic force of the spring 7 and extends out of the housing 4 for use. When the semicircular part of the cam 6 is aligned with the tool tail, the tool automatically retracts into the housing 4 under the action of the spring 7.

[0067] In this invention, the rotating shaft 1 is inserted into the mounting hole corresponding to the cam 6. When the rotating shaft 1 rotates, it drives the cam 6 to squeeze the tail of the tool, thereby realizing the extension and retraction of the tool.

[0068] After the rotating shaft 1 and cam 6 are engaged, they are inserted into the mounting hole (small cylindrical hole 12) at the bottom of the housing 4. Spring 7 is then fitted into the tool slot on the housing 4. The cover plate 2 is secured to the threaded hole 13 on the housing 4 with screws to complete the assembly. Rotating the rotating shaft 1 drives the cam 6 to rotate. When the long end of the cam 6 contacts the tool tail, it compresses the tool, causing it to extend. When the circular part of the cam 6 contacts the tool tail, the tool retracts into the housing 4 under the pressure of the spring. When the tool is needed, rotating the rotating shaft 1 extends the tool head; when the tool is not in use, rotating the rotating shaft 1 retracts the tool into the housing 4.
