Description

A kind of screwdriver that has chuck
Technical field
The utility model relates to screwdriver, and a kind of screwdriver that has chuck that is applicable to that working space is narrow and small is provided especially.
Background technology
Screwdriver is to be used to tighten or unscrew the instrument that screw uses, conventional screwdriver structure is simple, a lot of inconvenience is arranged during for the narrow and small screw in disassemble and assemble work space, during the dismounting screw, need a hand to take screwdriver, and the another hand pinch screw and operate, but sometimes because working space is narrow and small, make screw be easy to drop, brought very big difficulty to work.
Magnetic screw driver at head it off is arranged in the market,, prevent that the accident of screw from dropping, but, still can occur the phenomenon that the screw accident drops again and again because the magnetic force of magnetic cutter head is limited after all by adsorbing screw at the magnetic cutter head.
Therefore, in order effectively to address the above problem, people are seeking a kind of screwdriver of new structure always.
The utility model content
The purpose of this utility model is to provide a kind of screwdriver that has chuck, the problem that screw drops easily when dismantling screw to solve.
The screwdriver that has chuck that the utility model provides, this screwdriver comprises handle 1, knife bar 2 and cutter head 3, the upper end of described knife bar 2 links to each other with handle 1, and the lower end of described knife bar 2 links to each other with cutter head 3, it is characterized in that: described screwdriver also comprises screw chuck 4; Described screw chuck 4 is pre-large post-small horn shape, and the front end of screw chuck 4 is claw type structure 41, and the rear end of screw chuck 4 is provided with installing hole, and installing hole is being nested with rotary sleeve 5, and rotary sleeve 5 is fixed in the groove on knife bar 2 tops by jump ring; And described screw chuck 4 can be a track with the junction of itself and rotary sleeve 5, is axle center 360 degree rotations with knife bar 2.
The screwdriver that has chuck in the utility model is equipped with the design of screw chuck by this screw chuck at the knife bar place of screwdriver, can catch screw to prevent that it from dropping unexpectedly by the claw type structure that screw clamp puts when the dismounting screw; In addition, this screw chuck is connected with knife bar with jump ring by rotary sleeve, and the screw chuck can be with respect to the 360 degree rotations of positions such as rotary sleeve and knife bar, when the screw at narrow and small place, dismounting space, can the hand-tight screw chuck of holding, the another hand-screw changes screwdriver, and the screw chuck can maintain static in this process, improved the stability of screw clamp cover clamping screw effectively, prevented that the accident of screw from dropping.
Wherein, the claw type structure optimization is that front end 90 degree of screw chuck curves inwardly, because screw chuck integral body is tubaeform, so the inward flange of claw type structure just in time is circle, conforms to the top shape of screw, thereby catches screw better, prevents to drop.
And when need not to use the screw chuck, can be directly with the screw chuck along the knife bar removal, the dismounting of this screw chuck is flexible, and is easy to use, applicable to various forms of screwdrivers.
Preferably, described rotary sleeve 5 integral body are column type, and its one week of lower end is provided with boss; The top edge inside of described installing hole is provided with groove; Can cooperatively interacting between boss and the groove, interlock is relative rotates; By this structure Design, not only can reach the screw chuck purpose of rotary sleeve and knife bar 360 degree rotations relatively, and also simple in structure, with low cost.In addition we rotary sleeve can also be replaced with bearing etc. can reach the screw chuck can be with respect to other devices of knife bar rotation.
Further preferred, the front portion of described screw chuck 4 is provided with otch 42, and the outside of screw chuck 4 is with lock tube 8, and lock tube 8 can slide up and down in the outside of screw chuck 4; Wherein, by front portion otch is set at the screw chuck, make screw chuck front end be used for the conversion that the claw type place bore of clamping screw can be random, if screw hour, can be with lock tube to lower slider, make screw clamp be enclosed within incision and partially overlap, and then turn the bore at claw type place down, to make things convenient for the clamping of screw; And when screw is big, lock tube upwards can be slided, screw clamp is enclosed within otch and goes to open, and then transfers the bore at big claw type place, therefore by the design of said structure, can enlarge the scope of application of screwdriver, is applicable to the screw disassemble and assemble work of different sizes.
Further preferred, the inwall of described screw chuck 4 is provided with magnet; When being provided with this screwdriver dismounting screw, not only have the screw chuck can the clamping screw, and the magnet that is provided with in its inwall also can have the active force of absorption to screw, and then more effectively prevented screw beyond drop.
Further preferred, described cutter head is yi word pattern, cross, blossom type or interior six column types, thereby makes this screwdriver can be adapted to the screw disassemble and assemble work of different model, enlarges its scope of application.
The screwdriver that has chuck that the utility model provides, advantage is: simple in structure, easy to use, cost of manufacture is low, and is applied widely, and the phenomenon of effectively having avoided dropping beyond the screw takes place.
