Description

Multi-functional labor-saving screwdriver

Technical field

The utility model relates to a kind of hardware & tools, relates in particular to a kind of Multi-functional labor-saving screwdriver.

Background technology

Screwdriver is to be a kind ofly used for twisting screw to force its instrument in place, can insert in the line of rabbet joint or recess of screw cap, and the scope of application is very extensive, is the indispensable instrument of maintenance and daily life.But due to the design feature of conventional screw-driver in order, the grasping member of must exerting oneself in the process of twisting, presses down and turning handle very arduously, easily there is skidding in hand and handle place now, the power loss causing is larger, easily causes human body scratch when error, wastes time and energy and dangerous; In addition, for some bolts, when dismantling and tightening, need to use special box spanner, these instruments, owing to being of little use, so average family generally can not be purchased, have also caused thus and have used inconvenience.

Utility model content

The utility model, in order to solve weak point of the prior art, provides a kind of Multi-functional labor-saving screwdriver, can labour-saving installation and removal screw and bolt.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: Multi-functional labor-saving screwdriver, comprise the screwdriver knife bar of metal and the screwdriver handle being fixedly connected with it, the tail end of described screwdriver handle is provided with the first sleeve, on the outer wall of the first sleeve, be fixedly installed cross bar, one end of the first sleeve offers the cavity inserting for screwdriver handle tail end, on the sidewall of the cavity of the first sleeve, offer screwed hole, in screwed hole, pass and have bolt, in screwed hole, be provided with the screw thread corresponding with described bolt, the head of bolt is positioned at the first sleeve outside, one end that bolt is positioned at the first sleeve inner is fixedly installed elastomeric pad, the tail end of screwdriver handle inserts cavity, described elastomeric pad suppresses screwdriver handle, the other end of the first sleeve is fixedly installed box spanner, and the opening direction of the collet head of box spanner is contrary with the cutter head pointing direction of described screwdriver knife bar.

The quantity of described screwed hole is two, and two screwed holes lay respectively at the both sides of described screwdriver handle; The quantity of described bolt is two.

Described elastomeric pad is made up of rubber.

The collet head of described box spanner is hexagonal blind hole or 12 jiaos of blind holes.

The cutter head of described screwdriver knife bar is in-line or cross.

The beneficial effects of the utility model: the tail end of screwdriver handle is provided with the first sleeve, on the outer wall of the first sleeve, be fixedly installed cross bar, one end of the first sleeve offers the cavity inserting for screwdriver handle tail end, on the sidewall of the cavity of the first sleeve, offer screwed hole, in screwed hole, pass and have bolt, in screwed hole, be provided with the screw thread corresponding with described bolt, the head of bolt is positioned at the first sleeve outside, one end that bolt is positioned at the first sleeve inner is fixedly installed elastomeric pad, the tail end of screwdriver handle inserts cavity, described elastomeric pad suppresses screwdriver handle, said structure design can make the first sleeve and screwdriver handle be fastenedly connected, in the process of twisting, the rotational of cross bar is well transferred on the cutter head of screwdriver knife bar, installation and removal screw is more laborsaving than conventional screw-driver in order, obviously reduce labour intensity and work difficulty, the other end of the first sleeve is fixedly installed box spanner, the opening direction of the collet head of box spanner is contrary with the cutter head pointing direction of described screwdriver knife bar, this structural design can mount and dismount bolt, when use, the collet head of box spanner is inserted in the head of bolt, in the process of twisting, the rotation of cross bar is transferred to the collet head of box spanner, can labour-saving installation and removal bolt.

The utility model is reasonable in design, simple in structure, be easy to manufacture, can labour-saving installation and removal screw and bolt, obviously reduce labour intensity and work difficulty.
