Description

A kind of screwdriver

Technical field

The utility model relates to hardware & tools, relates to a kind of screwdriver or rather.

Background technology

At present, market there is folding screwdriver, for making screwdriver volume reduce to be easy to carry by folding for screwdriver knife bar and do not agree to that scuffing people or object are mostly all still realized by magnetisable material absorption screwdriver knife bar, but this structural instability and magnetisable material magnetic after extrusion and collision can weaken, cause screwdriver knife bar can not be stably fixed on screwdriver hilt, make result of use not good.

Utility model content

The technical problems to be solved in the utility model is, provides a kind of good fixing effect and a kind of screwdriver easy to use.

Technical solution of the present utility model is, a kind of screwdriver with following structure is provided, comprise screwdriver handle of a knife and screwdriver knife bar, described screwdriver handle of a knife is provided with the holding tank holding screwdriver knife bar, described screwdriver knife bar one end is hinged on holding tank upper end inwall through jointed shaft, described jointed shaft one end is fixedly connected with the spill spin block being provided with bayonet socket, be provided with in described screwdriver handle of a knife and the cavity rotated for spill spin block, the fixed block matched with bayonet socket is sliding combined with in described cavity, be provided with between described cavity and fixed block and make fixed block and the inconsistent elastic component of bayonet socket, described fixed block is fixedly connected with jug, described cavity sidewalls is provided with the groove slided for handle with cavity connects.

After adopting above structure, a kind of screwdriver of the present utility model, compared with prior art, have the following advantages: fix jointed shaft by spill spin block and make screwdriver knife bar, simple and reliable for structure, be not easy by ectocine, good fixing effect and not yielding, being coordinated with spill spin block upper latch notch by fixed block makes spill spin block fix, operation fixed block just can be opened or Foldable screwdriver knife bar, facilitate easy to operate, and position on spill spin block can be positioned at by arranging bayonet socket, screwdriver knife bar is realized to be fixed in different angles, make screwdriver more easy-to-use, especially position screwdriver knife bar and screwdriver handle of a knife being fixed into 90 degree is made, there is the larger arm of force, be convenient to turn the screw being difficult to turn, because described fixed block is provided with handle, described cavity sidewalls is provided with the groove slided for handle with cavity connects, fixed block coordinates by handle and elastic component the position realizing fast operating fixed block, realize opening fast and folding of screwdriver knife bar, make people's practicality convenient.

Improve as one of the present utility model, described bayonet socket is 3, described adjacent bayonet socket respectively and between the line at spill spin block center angle be 90 degree, namely achieve screwdriver knife bar to be positioned at holding tank, completely to open and to become with screwdriver hilt 180 degree and screwdriver knife bar and screwdriver hilt to be the fixing of 3 positions of 90 degree, screwdriver can be convenient for carrying and easy to use, especially position screwdriver knife bar and screwdriver handle of a knife being fixed into 90 degree is made, there is the larger arm of force, more convenient to use.
