Description

Technical Field

[0001] This utility model relates to the field of precision screwdriver technology, and in particular to a novel head-shaking screwdriver. Background Technology

[0002] In the craft of precision watch repair, especially in the disassembly and assembly of screws on concealed push-button components inside the case of high-end watches, the use of traditional screwdrivers faces significant technical challenges. These tasks require tools that not only possess high operational precision but also adapt to extremely confined operating spaces and complex geometric constraints. While widely used in watch repair, traditional screwdrivers, based on a linear drive design, exhibit significant limitations when handling specialized disassembly and assembly tasks such as push-button screws located inside the watch case, where space is limited and the axis may be offset due to the case structure.

[0003] Specifically, traditional screwdrivers are designed with the screwdriver axis strictly aligned with the screw axis, a principle that is highly effective in open, unobstructed operating environments. However, in watch repair scenarios, especially when dealing with push-button screws located on the edge or inside the watch case, close to other precision components, perfect alignment of the traditional screwdriver axis with the screw axis becomes virtually impossible. This misalignment not only significantly increases the risk of the screwdriver slipping but can also damage or break the screw head due to improper force, potentially causing irreversible damage to the watch's overall structure and function.

[0004] While the industry has attempted to alleviate this problem by improving operating techniques, employing auxiliary positioning devices, or using specially designed extension rods, these methods are often cumbersome, inefficient, and fail to fundamentally solve the disassembly and assembly difficulties caused by space constraints and axis misalignment. Furthermore, these temporary solutions may introduce additional operational errors, further increasing the risk of damage to watch components. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a new type of swivel screwdriver, which solves the technical problems of low operating accuracy, easy slippage, and easy damage to screws and watch parts caused by traditional screwdrivers due to space limitations and misalignment of the axis when disassembling and assembling screws of concealed button components inside the watch case.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0046] Furthermore, the first mounting protrusion 111 and the adapter 20 are respectively provided with a first insertion through hole 113 and a first mounting hole 21 that are adapted to the first rotating shaft 30. This design allows the first rotating shaft 30 to be accurately and securely installed between the two, enabling smooth rotation of the adapter 20 while ensuring the stability and durability of the structure. The adapter 20 also has a first arc-shaped relief groove 22 at the end near the operating handle 11. The first arc-shaped relief groove 22 is located on both axially symmetrical sides of the first rotating shaft 30. This design helps to reduce interference of the adapter 20 during operation and improves the smoothness and flexibility of rotation.

[0047] The rear sleeve 12, away from the operating handle 11, has a mounting groove 121 that matches the decorative cover 80. This structure allows the decorative cover 80 to be securely installed on the rear sleeve 12, serving both a decorative function and protecting the internal structure of the rear sleeve 12. The other end of the rear sleeve 12 has a mounting through hole 122 that matches the mounting post 112. The mounting through hole 122 extends through the mounting groove 121, and the mounting post 112 passes through the mounting through hole 122 and extends into the mounting groove 121, where it is screwed to the decorative cover 80 located in the mounting groove 121. This connection method is not only firm and reliable but also facilitates disassembly and maintenance.

[0048] The outer surface of the operating handle 11 is provided with rough texture 90. This design can increase the friction when the user holds it, and improve the stability and safety during operation. The outer periphery of the first mounting protrusion 111 near the adapter 20 is provided with a first guide slope 114 to avoid interference with the rotation structure, so that the adapter 20 can rotate more smoothly.

[0049] The end of the screwdriver sleeve 40 near the adapter 20 has a second mounting protrusion 41. The second mounting protrusion 41 is movably mounted on the end of the adapter 20 away from the first rotating shaft 30 via a second rotating shaft 50. This design allows the screwdriver sleeve 40 to rotate independently relative to the adapter 20, thereby further increasing the operational flexibility of the screwdriver. A second guide bevel 42 is provided on the outer periphery of the end of the adapter 20 near the screwdriver sleeve 40, further ensuring the independent rotation performance of the screwdriver sleeve 40 relative to the adapter 20 and avoiding structural interference.
