Description

Technical Field

[0001] The utility model belongs to the technical field of screwdrivers, and in particular relates to a screwdriver handle. Background Art

[0002] A screwdriver is a common tool used to turn a screw into place, usually with a thin wedge-shaped head that fits into the slot or recess in the screw head.

[0003] The screwdriver in the prior art includes a screwdriver handle and a screwdriver bit, and the screwdriver bit is fixed in the mounting hole of the screwdriver handle. The prior art discloses a utility model patent named a multifunctional screwdriver handle (authorization announcement number: CN216399521U), and the bit is installed by a spring and a card block, which is easy to install and not easy to damage.

[0004] The screwdriver handle shell of the prior art is cylindrical, and the screwdriver may fall off when being used. Utility Model Content

[0005] The utility model aims to solve the above-mentioned technical problems existing in the prior art and provides a screwdriver handle. The shape of the handle is designed so that a groove is formed on the handle body, and the user's hand is limited on the groove to reduce the possibility of the screwdriver falling when in use.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A screwdriver handle comprises a handle body, the end of the handle body for inserting a screwdriver bit is end one, and the other end of the handle body is end two. The invention is characterized in that the handle body comprises handle part one, handle part two, handle part three and handle part four, and mounting holes are arranged between handle part one, handle part two, handle part three and handle part four, and handle part one is provided with an opening, which is connected to the mounting hole, and the screwdriver bit is installed in the mounting hole through the opening.

[0008] The handle part 2 is connected to the handle part 1, and the cross-sectional area of ​​the handle part 2 is smaller than the cross-sectional area of ​​the handle part 1. Meanwhile, the cross-sectional area of ​​the handle part 2 gradually decreases from the end part 1 to the end part 2.

[0009] The handle part three connects the handle part two and the handle part four, and the cross-sectional area of ​​the handle part three gradually increases from the end part one to the end part two, so that a groove is formed in the handle body.

[0010] The diameter of the handle part 2 of the utility model is reduced, which is convenient for the user to hold. At the same time, the user's hand is limited between the handle part 1 and the handle part 4, so that the user's hand is limited on the groove of the handle body, reducing the possibility of the screwdriver falling when in use.

[0011] Furthermore, handle part one, handle part two, handle part three and handle part four are an integrally formed structure, which is convenient for integrally formed manufacturing.

[0012] Furthermore, the handle body is provided with a limiting groove, and an anti-skid layer is fixed in the limiting groove. The anti-skid layer plays an anti-skid role, making it convenient for the user to hold the screwdriver handle tightly for easy operation.

[0013] Furthermore, the anti-slip layer is made of rubber, which has the characteristics of good elasticity and softness, and can improve the comfort of holding the handle.

[0014] Furthermore, the top of the anti-skid layer extends toward end portion one and wraps around handle portion one, so that the anti-skid layer is firmly attached to the outer side of the handle body, thereby preventing the anti-skid layer from falling off.

[0015] Furthermore, the anti-slip layer is provided with a through hole one, so that the outer surface of the handle body is exposed to form a contact area one. At the same time, the anti-slip layer is provided with a through hole two, and the through hole two is arranged below the through hole one, so that the outer surface of the handle body is exposed to form a contact area two, thereby reducing the material used in the anti-slip layer and reducing the cost. At the same time, the contact area one and the contact area two form an edge to prevent the screwdriver handle from slipping when in use.

[0016] Furthermore, the outer surface of the handle body is provided with anti-skid patterns, and the anti-skid patterns are correspondingly arranged in the contact area 2. The anti-skid patterns can play an anti-skid role and ensure the normal use of the screwdriver.

[0017] Furthermore, an arc surface is provided between the end portion 1 and the handle body to avoid stress concentration between the end portion 1 and the handle body.

[0018] Furthermore, an elastic pad is provided at the bottom of the mounting hole, and the pad is provided with a limiting hole. When the screwdriver bit is inserted into the mounting hole, the end of the screwdriver bit extends into the limiting hole, so that the pad limits the end of the screwdriver bit, thereby increasing the stability of the screwdriver bit in the screwdriver handle.

[0019] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0020] The utility model has an ingenious and reasonable structural design and strong practicality. By designing the shape of the handle, a groove is formed on the handle body, and the user's hand is limited on the groove, which fits the natural curve of the hand more closely and is more convenient for actual grip, thereby reducing the possibility of the screwdriver falling when in use. The double design of the anti-skid layer and the anti-skid pattern further enhances the gripping stability of the handle surface, increases the friction between the handle and the hand, and increases the anti-skid effect, making the screwdriver less likely to slip during use, thereby improving the stability and safety during operation.
