Description

Screwdriver head with anti-skid groove

Technical Field

The utility model belongs to the technical field of screwdriver bits, and particularly relates to a screwdriver bit with an anti-skidding groove.

Background

The bit generally refers to a screwdriver bit mounted to a screwdriver for screwing. The screwdriver head is an electric screwdriver used for fastening or loosening screws and belongs to small electric tools. However, as shown in fig. 1, 4, 6, 8, and 10, the conventional bit has a smooth end surface and is easy to slip when screwing, and the friction between the head of the bit and the screw is small, which tends to shorten the service life of the bit.

Disclosure of Invention

The screwdriver bit aims to solve the problems that the end surface of the existing screwdriver bit is smooth and easy to slip when a screw is screwed, and the friction force between the head of the screwdriver bit and the contact part of the screw is small, so that the service life of the screwdriver bit is easy to shorten; the utility model aims to provide a screwdriver bit with an anti-skidding groove.

The screwdriver head with the anti-skidding grooves comprises a screwdriver head body, wherein the plane of the head of the screwdriver head body is provided with the inwards-concave anti-skidding grooves.

Preferably, the anti-slip groove is in a cross shape or a straight shape or other shapes.

The axial anti-skidding can be realized, so that the bit is not easy to skid during disassembly and assembly, and the service life of the bit can be prolonged;

the structure is simple, the design is reasonable, the friction force between the screw and the screw can be increased, and the stability is improved.

Detailed Description

In order that the objects, aspects and advantages of the utility model will become more apparent, the utility model will be described by way of example only, and in connection with the accompanying drawings. It is to be understood that such description is merely illustrative and not intended to limit the scope of the present invention. The structure, proportion, size and the like shown in the drawings are only used for matching with the content disclosed in the specification, so that the person skilled in the art can understand and read the description, and the description is not used for limiting the limit condition of the implementation of the utility model, so the method has no technical essence, and any structural modification, proportion relation change or size adjustment still falls within the range covered by the technical content disclosed by the utility model without affecting the effect and the achievable purpose of the utility model. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the scheme according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.

As shown in fig. 2 and 3, the following technical solutions are adopted in the present embodiment: the screwdriver bit comprises a screwdriver bit body 1, wherein a concave anti-skidding groove 11 is formed in the head plane of the screwdriver bit body 1.

As shown in fig. 2, 3, 5, 7, 9, and 11, further, in the present embodiment, the anti-slip groove 11 is cross-shaped, or in-line, or in-plum, or in other shapes, which can be designed according to the structure of the batch head.

The working principle of the specific embodiment is as follows: when the screwdriver head is used, when the screwdriver head is detached and installed, axial force is often applied to the screwdriver head, the anti-slip groove 11 in the screwdriver head can increase friction force, the phenomenon of slipping is not prone to occurring, the stability is further improved, and the service life of the screwdriver head is prolonged.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.

Claims

1. The utility model provides a criticize head with antiskid groove, includes criticize first body, its characterized in that: the head plane of the batch head body is provided with an inwards concave anti-slip groove.
