Abstract

The utility model discloses a multifunctional bit which comprises a clamping part, a transition connecting part and a working head part. The clamping part, the transition connecting part and the working head part are sequentially connected with each other. A clamped groove with the diameter contracting inwardly is arranged on the clamping part, a prong and one of a concave circular-arc-shaped groove and a ring-shaped convex plate are arranged on an end face of the working head part. By arranging the prong and one of the concave circular-arc-shaped groove and the ring-shaped convex plate on the working head part, the multifunctional bit has the advantages of being capable of not only being used for adjusting a bolt, but also for dinting a dent, punching a hole on a sheet, riveting a rivet and the like, and being convenient to use, time-saving and labor-saving.

Description

Multi-functional screwdriver bit
Technical field
The utility model relates to a kind of screwdriver bit, refers to especially a kind of multi-functional screwdriver bit.
Background technology
Existing screwdriver bit all is single hexgonal structure, decussate texture, only be used for adjusting bolt, yet all need to beat the location pit in the general bolt use procedure, bore connecting hole etc., rivet also usually together uses with bolt in the use of connector, this just need to play repeatedly replacing use between location pit, drill bit, electric tool and the riveted tool, the instrument that needs is many, and operation is many, time-consuming, effort.
The utility model content
In order to overcome defects, the utility model provides a kind of multi-functional screwdriver bit, and this multi-functional screwdriver bit is simple in structure, both can be used for adjusting bolt and also can be used for playing indenture, thin plate punching, riveted rivet etc., and is easy to use, time saving and energy saving.
The technical scheme that the utility model adopts in order to solve its technical problem: a kind of multi-functional screwdriver bit, comprise a clamping part, a transition connecting portion and a work head, described clamping part, transition connecting portion and the head of being connected connect successively, clamping part is provided with the clamping groove that diameter inside contracts, and described working head end surface is provided with a kind of in tip, indent arc groove and the annular boss.
As further improvement of the utility model, described clamping part and work head are a kind of in hexagonal structure, the cross structure.
As further improvement of the utility model, the lateral wall of described annular boss is towards clamping part one end diameter greater than the truncation cone structure towards work head one end, and madial wall is tapered blind hole.
As further improvement of the utility model, the truncation cone structure of described annular boss is coaxial with tapered blind hole.
As further improvement of the utility model, the clamping groove of described clamping part is ring-type arc groove structure.
The beneficial effects of the utility model are: the utility model arranges a kind of in tip, indent arc groove and the annular boss by the work head at screwdriver bit, it both can be used for adjusting bolt also can be used for beating indenture, thin plate punching, riveted rivet etc., easy to use, time saving and energy saving.

The specific embodiment
Embodiment: a kind of multi-functional screwdriver bit, comprise a clamping part 1, one transition connecting portion 2 and a work head 3, described clamping part 1, transition connecting portion 2 connects successively with the head 3 of being connected, clamping part 1 is provided with the clamping groove that diameter inside contracts, it is characterized in that: described work head 3 end faces are provided with tip 4, a kind of in indent arc groove 5 and the annular boss 6, during use, this screwdriver bit is installed on the impact chuck, it can be used for adjusting bolt, when work head 3 is provided with tip 4, can be used for getting indenture at workpiece, this kind structure is applicable to self-tapping screw, in the time of on plate packed self-tapping screw into by needs, directly beat an indenture with this screwdriver bit at plate first, then just can directly self-tapping screw be aimed at indenture screws in, saved the step of plate centering, when using the small size rivet, the rivet column can be inserted in the indent arc groove 5 of work head 3, then by the impact chuck rivet being impacted can be with closing-up on workpiece, need not to make separately riveting tool, when needs during at thin plate punching installation connecting element, only need to go out a hole at thin plate with the screwdriver bit with ring-type boss 6, need not to use boring bar tool, easy to use, need not repeatedly to change instrument.
Described clamping part 1 and work head 3 are a kind of in hexagonal structure, the cross structure, are convenient to regulate turret head and Phillips head bolts, can certainly be other structures such as triangular structure etc., get final product with the bolt head structure matching that cooperates.
The lateral wall of described annular boss 6 is towards clamping part 1 one end diameters greater than the truncation cone structure towards work head 3 one ends, and madial wall is tapered blind hole.
The truncation cone structure of described annular boss 6 is coaxial with tapered blind hole.
The clamping groove of described clamping part 1 is ring-type arc groove structure.
