Description

Technical Field

[0001] This application relates to the field of hardware tools, and more specifically, to a spring mechanism for a quick-release screwdriver hexagonal bit. Background Technology

[0002] Impact screwdrivers are widely used in the machinery and construction industries. Their main function is to quickly tighten screws. During use, because screws come in different sizes, it is necessary to change to a suitable hex screwdriver bit. They also need to be easy to operate and have a structure that prevents the hex screwdriver bit from falling off. Summary of the Invention

[0003] The purpose of this application is to provide a spring mechanism for quick-release screwdriver hexagonal bits, which can solve the technical problem of screwdriver hexagonal bit replacement.

[0004] This application provides a spring mechanism for a quick-release screwdriver hexagonal bit, including an output shaft and a spring mechanism. The output shaft has a groove for the hexagonal bit to pass through. At least one first mounting groove is provided on the side wall of the output shaft, and the first mounting groove communicates with the groove. A steel ball is disposed in the first mounting groove. The spring mechanism includes a retaining ring, a housing, and a first elastic element. The retaining ring is fixed to the outer wall of the output shaft, and the housing is movably sleeved on the outer wall of the output shaft. The inner wall of one end of the housing is slidably connected to the retaining ring, and the inner wall of the other end of the housing has a recess. One end of the first elastic element abuts against the retaining ring, and the other end of the first elastic element abuts against the housing.

[0005] Preferably, the outer casing is provided with a second mounting groove, which communicates with the first mounting groove, and a second elastic element is provided in the second mounting groove, which abuts against the steel ball.

[0006] Preferably, the inner wall of the outer casing near the end of the retaining ring has a protrusion.

[0007] Preferably, the outer wall of the outer casing is provided with anti-slip texture.

[0008] Preferably, the first elastic element is a spring.

[0009] Preferably, the second elastic element is a spring.

[0010] The beneficial effects of this utility model are:

[0011] The quick-release screwdriver hexagonal bit provided by this utility model has an elastic mechanism that pushes the outer shell when disassembling the hexagonal bit. The outer shell moves towards the side closer to the retaining ring and squeezes the first elastic element. As the recessed part moves, a clearance space is formed between the recessed part and the first mounting groove, allowing the steel ball to move away from the hexagonal bit. This enables quick disassembly or insertion of the hexagonal bit and improves the ease of use. Attached Figure Description

[0026] Example 1

[0027] like Figure 1 , Figure 2 and Figure 5As shown, this application embodiment provides a spring mechanism for a quick-release screwdriver hexagonal bit, including an output shaft 1 and a spring mechanism 2. The output shaft 1 has a groove 4 for the hexagonal bit 3 to pass through. At least one first mounting groove 5 is provided on the side wall of the output shaft 1, and the first mounting groove 5 communicates with the groove 4. A steel ball 6 is provided in the first mounting groove 5. The spring mechanism 2 includes a retaining ring 7, a housing 8, and a first elastic member 9. The retaining ring 7 is fixed on the outer wall of the output shaft 1, and the housing 8 is movably sleeved on the outer wall of the output shaft 1. The inner wall of one end of the housing 8 is slidably connected to the retaining ring 7, and the inner wall of the other end of the housing 8 has a recess 10. One end of the first elastic member 9 abuts against the retaining ring 7, and the other end of the first elastic member 9 abuts against the housing 8. When the hexagonal bit 3 is not installed, the housing 8 blocks the first mounting groove 5 and restricts the steel ball 6, and the steel ball 6 extends partially into the groove 4.

[0028] In use, push the outer casing 8, and the outer casing 8 moves towards the side closer to the retaining ring 7 and squeezes the first elastic member 9. As the recessed part 10 moves, a clearance space is formed between the recessed part 10 and the first mounting groove 5, allowing the steel ball 6 to move away from the hexagonal bit 3. This allows for quick disassembly or insertion of the hexagonal bit 3. After inserting the hexagonal bit 3, release the outer casing 8, and the first elastic member 9 rebounds and pushes the outer casing 8 back to its initial position. This causes the outer casing 8 to block the first mounting groove 5 again and push the steel ball 6 against the limiting groove 14 of the hexagonal bit 3. Under the restriction of the outer casing 8, the steel ball 6 cannot move towards or away from the hexagonal bit 3, thus preventing the hexagonal bit 3 from falling off.

[0029] In this embodiment, the inner wall of the outer shell 8 near the retaining ring 7 has a protrusion 13. After the outer shell 8 moves to a certain position, the protrusion 13 contacts the retaining ring 7, and the retaining ring 7 limits the movement of the outer shell 8.

[0030] In this embodiment, the outer wall of the outer shell 8 is provided with anti-slip texture. The anti-slip texture is used to increase friction and facilitate pushing the outer shell 8.

[0031] In this embodiment, the first elastic element 9 is a spring.

[0032] Example 2

[0033] like Figure 1-5 As shown, compared with Embodiment 1, the difference in this embodiment is that the outer shell 8 is provided with a second mounting groove 11, which is connected to the first mounting groove 5. At this time, the first mounting groove 5 is designed as an elliptical structure, and a second elastic member 12 is provided in the second mounting groove 11, which abuts against the steel ball 6.

[0034] When disassembling the hexagonal screwdriver bit 3, push the housing 8. The housing 8 moves towards the side closer to the retaining ring 7 and squeezes the first elastic member 9. As the recess 10 moves, a clearance space is formed between the recess 10 and the first mounting groove 5, allowing the steel ball 6 to move away from the hexagonal screwdriver bit 3, thereby enabling the hexagonal screwdriver bit 3 to be disassembled quickly.

[0035] When the hexagonal screwdriver bit 3 is inserted, without pushing the outer casing 8, the hexagonal screwdriver bit 3 applies a force to the steel ball 6. The steel ball 6 moves towards the second mounting groove 11 and compresses the second elastic element 12. After the hexagonal screwdriver bit 3 is installed, the second elastic element 12 rebounds and pushes the steel ball 6 back to its initial position, so that the steel ball 6 again presses against the limiting groove 14 of the hexagonal screwdriver bit 3. Thus, the outer casing 8 does not need to be pushed when inserting the hexagonal screwdriver bit 3, achieving the convenient effect of quickly inserting the hexagonal screwdriver bit 3.

[0036] In this embodiment, the second elastic element 12 is a spring.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
