Description
Technical field
The utility model belongs to the dismantling device field, relates in particular to a kind of screwdriver.
Background technology
At present, existing screwdriver is when screwing screw, at first the cutter head of screwdriver to be aimed at the cutter groove of screw head, then firmly be screwed screwdriver, in screwing the process of screwdriver, the cutter head of screwdriver is easy to skid off in the cutter groove of screw head, like this, need again again the cutter head of screwdriver to be aimed at the cutter groove of screw head, and again screw screwdriver, operate and bother very much, affect operating efficiency.
The utility model content
The purpose of this utility model is to provide a kind of screwdriver, the cutter head that is intended to solve screwdriver of the prior art easy problem from skidding off in the cutter groove of screw head when the dismounting screw.
The utility model is to realize like this, a kind of screwdriver, be used for the dismounting screw, the cylindrical positioning tube that comprises a plastic cement handle of a knife, a knife bar that is fixedly connected with described handle of a knife and a hollow, described positioning tube comprises a junction and a location division, described knife bar is arranged in described location division and with described connecting portion and is fixedly connected with, and the external diameter of described knife bar and the external diameter of described screw head are all less than the internal diameter of described location division.
Further, the sidewall of described location division offers some being uniformly distributed and the elongate slot parallel with the axis of described location division.
Particularly, the cutter head of described knife bar is the yi word pattern structure.
Particularly, the cutter head of described knife bar is cross structure.
Particularly, the end that described knife bar is connected with described connecting portion offers external screw thread, described connecting portion is connected an end and offers a tapped installing hole with described knife bar, described knife bar is arranged in described installing hole, the external screw thread of described knife bar and the screw-internal thread fit of described installing hole.
Further, the end that is connected with described handle of a knife of described knife bar offers at least one annular groove.
Further, the end that is connected with described handle of a knife of described knife bar is provided with some lug bosses.
Particularly, described lug boss is spherical, taper or cylindrical structural.
In the process of rotation handle of a knife, firmly locate screw head the location division of positioning tube due to the utility model, and therefore, the cutter head of knife bar can not skid off in the cutter groove of screw head, can complete soon the dismounting of screw, has significantly improved operating efficiency.
Description of drawings
Fig. 1 is the cutaway view of the screwdriver that provides of the utility model embodiment.
Fig. 2 is the cutaway view of the positioning tube that provides of the utility model embodiment.
The specific embodiment
as depicted in figs. 1 and 2, a kind of screwdriver that the utility model embodiment provides, be used for dismounting screw (not shown), this screwdriver comprises a plastic cement handle of a knife 1, the cylindrical positioning tube 3 of one knife bar 2 that is fixedly connected with handle of a knife 1 and a hollow, positioning tube 3 is used for screw head is positioned, positioning tube 3 comprises a junction 31 and a location division 32, knife bar 2 is arranged in location division 32 and with connecting portion 31, is fixedly connected with, the external diameter of knife bar 2 and the external diameter of screw head are all less than the internal diameter of location division 32, like this, screw head can enter in location division 32, thereby the cutter groove of screw head is coordinated with the cutter head of knife bar 2.
During screwdriver work of the present utility model, at first with the head of the location division of positioning tube 3 32 alignment screw, screw head is entered in the location division 32 of positioning tube 3,32 pairs of location divisions screw head positions, and the cutter head that makes knife bar 2 is positioned at the cutter groove of screw head, then rotate handle of a knife 1, handle of a knife 1 drives screw turns by knife bar 2, thereby screw is screwed in workpiece or in workpiece and screws out.
Due to the utility model the rotation handle of a knife 1 process in, firmly has located screw head the location division 32 of positioning tube 3, and therefore, the cutter head of knife bar 2 can not skid off in the cutter groove of screw head, can complete soon the dismounting of screw, significantly improve operating efficiency.
Particularly, the sidewall of described location division 32 offers some being uniformly distributed and the elongate slot (not shown) parallel with the axis of location division 32, and namely the shape of location division 32 is similar to the claw type structure, like this, can make location division 32 screw head that more easily is fixedly clamped.
Particularly, the cutter head of described knife bar 2 is the yi word pattern structure, can be also cross structure, all belongs to protection domain of the present utility model.
Particularly, the mode that is fixedly connected with between described knife bar 2 and connecting portion 31 is specially: the end that knife bar 2 is connected with connecting portion 31 offers the external screw thread (not shown), connecting portion 31 is connected an end and offers an installing hole with the internal thread (not shown) 33 with knife bar 2, during assembling, knife bar 2 is arranged in installing hole 33, the screw-internal thread fit of the external screw thread of knife bar 2 and installing hole 33, thus realized that the screw thread between knife bar 2 and connecting portion 31 is fixedly connected with.
Particularly, the end that described knife bar 2 is connected with handle of a knife 1 offers at least one annular groove 21, in the present embodiment, the end that knife bar 2 is connected with handle of a knife 1 offers three annular grooves 21, be coated on knife bar 2 by Shooting Technique when handle of a knife 1 after, what be connected between handle of a knife 1 and knife bar 2 is more firm, thereby has solved the problem that easily gets loose between handle of a knife 1 and knife bar 2 in screwing handle of a knife 1 process.
Further, be connected more firmly in order to make between handle of a knife 1 and knife bar 2, the utility model can also arrange at the end that knife bar 2 is connected with handle of a knife 1 some lug boss (not shown), lug boss can be spherical, taper or the structure such as cylindrical, these lug bosses can significantly improve the bonding strength between handle of a knife 1 and knife bar 2, thereby make, are connected more firmly between handle of a knife 1 and knife bar 2.
