Abstract

The utility model discloses a multidirectional curved bar screwdriver, it belongs to five metals apparatus field, its beneficial effect be can multidirectional bending transmission torsion. The utility model provides a realize like this that it includes tool bit, bearing, metal flexible axle, curved bar, main handle, assists the handle, the curved bar is directly two sections forms of corner bend, is connecting one section metal collapsible tube at the right -hand member of curved bar, passes in the metal flexible axle follow metal collapsible tube and is connected with the main handle. This design is used in being applicable to more constrictive operating space.

Description

Multidirectional curved bar screwdriver

Technical field

This utility model belongs to hardware & tools apparatus field, specifically refers to a kind of multidirectional curved bar screwdriver.

Background technology

Screwdriver is from a kind of instrument apparatus not in people's daily life and operation, screw or bolt is unloaded on being mainly used to, it is generally made up of the knife bar of handle and direct rod shape, the outer end of knife bar is that yi word pattern or criss-cross cutter head are to adapt to the head of a nail of different edge of a knife shape, knife bar and handle are on same axis, also require that this axis aligns the axis of screw and reverses screw driver handle while applying a pressure to screw to ensure reliably docking of driver bit and the screw head of a nail in use, the bigger this screwdriver in space of operation instrument use easily if can align to unload on screw, if and the space of the instrument of operation is restricted such as narrow space and is difficult to hold the screwdriver of whole, instrument now uses just highly difficult, though can be inadequate cutter head is directed at the head of a nail, but because the restriction of narrow space cannot accomplish that the axis of screwdriver and the axis of nail rod are on same axis, thus cannot transmit turning moment reliably, can not normal operating, in order to the life of convenient people in such cases and production are accomplished by a kind of screwdriver that the straight-bar of screwdriver can be transformed to the curved bar that can bend to adapt to narrow working place.

Summary of the invention

The purpose of this utility model is to provide the new multidirectional curved bar screwdriver of technical scheme of a kind of screwdriver, and it can meet above-mentioned needs.

The technical solution of the utility model is realized in, it includes cutter head, bearing, metal flexible axle, curved bar, main handle, auxiliary handle, described curved bar is two sections of shapes of square bending, right-hand member at curved bar is connected to one section of metal hose, and the traverse in metal hose of metal flexible axle is connected with main handle.

The beneficial effects of the utility model are: can the transmission torsion of multi-directional bending.

Accompanying drawing illustrates:

Fig. 1 be the design screwdriver front view (containing cutter head position and curved bar, connection by metal hose place partly cut open zoomed-in view).

In figure, 1 is cutter head, and 2 is bearing, and 3 is metal flexible axle, and 4 is curved bar, and 5 is auxiliary handle, and 6 is metal hose, and 7 is main handle.

Detailed description of the invention:

The design is illustrated below in conjunction with accompanying drawing.

As shown in Figure 1, coupled together by a metal flexible axle 3 between cutter head 1 and main handle 7, metal flexible axle is set in the tubulose curved bar 4 that rectangular sigmoid is two sections, between the lower end and the upper surface of curved bar 4 of the cutter head 1 containing boss, device has a pressure bearing 2, and the horizontal segment at curved bar 4 installs auxiliary handle 5;Right-hand member at curved bar 4 is connected to one section of metal hose 6, and metal flexible axle 3 continues across in metal hose 6 and couples together with main handle. time specifically used, both hands hold main handle 7 respectively, auxiliary handle 5, cutter head is aligned the edge of a knife at screw head of a nail position and applies a thrust in case anti-avulsion position, rotate main handle, torsional moment will be delivered to the cutter head of the other end by metal flexible axle, bearing also can this transmission of power-assisted without blocking, as shown in the figure, metal hose after curved bar latter end can be flapped toward in three dimensions in multidirectional Multi-angle free adjustment, namely it can give the well-to-do and capable rotation process space of main handle one and angle as required, thus in the working place of relatively narrower, complete that common straight-bar screwdriver can not complete on unload the operation of screw.

Claims

1. a multidirectional curved bar screwdriver, it includes cutter head, bearing, metal flexible axle, curved bar, main handle, auxiliary handle, it is characterized in that two sections of shapes that described curved bar is square bending, the right-hand member at curved bar is connected to one section of metal hose, and the traverse in metal hose of metal flexible axle is connected with main handle.
