Description

Technical Field

[0001] This utility model relates to the field of screwdriver technology, specifically to an anti-slip screwdriver. Background Technology

[0002] Screwdrivers, as a basic hand tool, are widely used in various repair, assembly, and manufacturing fields. Their main function is to tighten or loosen parts by rotating screws. However, in actual operation, due to sweaty or oily hands, or complex and changing operating environments, screwdrivers are prone to slipping during use. This not only affects work efficiency but can also cause hand injuries to the operator, or even damage the parts being assembled or repaired. Therefore, the market urgently needs a screwdriver that can effectively prevent slippage and improve operational safety and stability. Traditional screwdrivers often focus only on their basic function—the ability to rotate screws—while neglecting the actual needs and experience of the operator. Specifically, the friction between the screwdriver tip and the screw slot of traditional screwdrivers is often insufficient, leading to slippage when tightening or loosening screws. Furthermore, while the handle of traditional screwdrivers may incorporate some anti-slip design, its effectiveness is significantly reduced with prolonged use or when hands are sweaty. These shortcomings not only affect the operator's work efficiency and comfort but may also pose a threat to safety during operation. Therefore, traditional screwdrivers have significant shortcomings in terms of anti-slip performance and operational stability, and urgently need improvement.

[0003] For example, Chinese patent CN220719157U proposes an anti-slip screwdriver. This patent addresses the problem of screwdrivers easily slipping during use to some extent through a detachable head and handle design, as well as an anti-slip structure on the handle. However, this patent only solves the anti-slip problem of the screwdriver handle; it does not improve the stability of the connection between the screwdriver head and the handle, or the anti-slip performance of the screwdriver head itself. Although the patent increases friction during gripping through the anti-slip structure on the handle, in actual operation, when the screwdriver head contacts the screw slot, the screwdriver head may still slip due to factors such as the slot shape, screw material, or tightening force. Furthermore, although the screwdriver head and handle are detachable, the stability of the connection remains insufficient. With prolonged use or under high-intensity tightening operations, the connection may loosen or become damaged. Therefore, we propose an anti-slip screwdriver. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an anti-slip screwdriver, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a non-slip screwdriver, including a handle, a connector fixedly connected to the outer wall of one side of the handle, the inner wall of the connector away from the handle being hexagonal, and a locking head fixedly connected to the outer wall of the handle near the connector, the connector being located at one end of the inner wall of the locking head.

[0006] Preferably, a screwdriver bit is inserted into the inner wall of one end of the locking head, and an anti-slip head is provided on the outer wall of one end of the screwdriver bit, with the outer wall of the anti-slip head in frictional contact with the inner wall of the locking head.

[0007] Preferably, the screwdriver bit near the locking head is plugged into the output end of the connector.

[0008] Preferably, a locking collar is threaded to the outer wall of one end of the locking head, and one side of the inner wall of the locking head is tightly pressed against the outer wall of the screwdriver head.

[0009] Preferably, an anti-slip sleeve is fixedly connected to the outer wall of the end of the grip near the connector.

[0010] Preferably, the outer wall of the locking collar has multiple sets of anti-slip grooves distributed in a ring at equal intervals.

[0011] Preferably, the outer wall of the end of the handle away from the anti-slip sleeve is fixedly connected with anti-slip protrusions that are distributed in a ring at equal intervals.

[0012] Compared with the prior art, this utility model provides an anti-slip screwdriver, which has the following beneficial effects:

[0013] 1. This anti-slip screwdriver, compared to prior art document CN220719157U, discloses a detachable head and handle design, as well as an anti-slip structure on the handle. However, this application effectively improves the friction between the screwdriver head and the screw slot by adding an anti-slip head design. Traditional screwdrivers are prone to slippage during use due to insufficient friction between the head and the screw slot. This device features an anti-slip head on the outer wall of one end of the screwdriver head, forming frictional contact with the inner wall of the locking head, greatly increasing the stability of the screwdriver head during use and effectively preventing slippage. This design is more targeted than the anti-slip structure in the prior art document, directly solving the problem of screwdriver head slippage and representing a significant and substantial improvement.

[0014] 2. Regarding this anti-slip screwdriver, while the prior art document CN220719157U mentions an anti-slip structure for the handle, this application improves the stability of the connection between the screwdriver head and the handle by optimizing the connection structure. With traditional screwdrivers, the connection between the screwdriver head and the handle may loosen or become damaged under prolonged use or high-intensity tightening. This application ensures a secure connection between the screwdriver head and the handle through the tight fit of the locking head, connecting head, and locking collar, maintaining stability even under prolonged use or high-intensity operation. This design is more reliable than the detachable design in the prior art document, improving the screwdriver's lifespan and safety.

[0015] 3. This anti-slip screwdriver, compared to prior art document CN220719157U, while focusing on the anti-slip design of the handle, comprehensively considers the anti-slip properties of the screwdriver head and connection stability, thus improving overall operational safety and efficiency. Traditional screwdrivers are deficient in anti-slip performance and operational stability, easily causing hand injuries or damage to parts. This application, through the design of an anti-slip head and optimized connection structure, solves the problem of screwdriver head slippage and improves the stability of the connection, making operation safer and more efficient. This comprehensive design is more comprehensive and practical than the single anti-slip design in the prior art document, demonstrating significant advantages and progress.
