Description

A kind of quick screwdriver combination tool

Technical field

The utility model relates to a kind of instrument of installing and removing screw, particularly a kind of quick screwdriver combination tool.

Background technology

Screwdriver is that power industry must indispensable instrument, and substation equipment maintenance and repair specialty or relay protection specialty all be can use screwdriver, and existing screwdriver is divided into by edge of a knife type: " flat mouth " screwdriver and " cross " screwdriver.

Although on market, screwdriver combined tool is arranged also now, screwdriver rod can separate with handle of a knife, but interconnect not ideal enough both: a kind of is that an end of driver bit is outer six sides, handle of a knife is interior six sides, what both, connection was leaned on is magnetic force, connect firmly not, easily come off, also can exert an influence to precision instrument in boundary of works area; Another kind is that knife bar is connected screw to connect with handle of a knife, connects fasteningly, and when firmly slightly large, screw thread easily damages, and causes cutter head to be difficult for taking-up, and it is convenient not to change.

No matter be existing screwdriver combined tool, or normal screws cutter, all exist certain not enough: when the turn of the screw, withstand the afterbody of screwdriver with palm, being close to the finger of holding screwdriver middle part is rotated, each rotational angle is approximately 150 degree, when rotating next time, in order to prevent coming off of screwdriver, palm and screwdriver contact-making surface still need keep certain dynamics, and the revolution of palm has driven the convolution of screwdriver, thereby have done idle work, and waste the time, therefore need a kind of more practical instrument of development.

Summary of the invention

The utility model is intended to solve existing normal screws cutter and the not high problem of combination screw driver efficient,Provide a kind of rational in infrastructure, it is firm, easy to use to connect, and has both avoided flogging a dead horse, time saving and energy saving again, the quick screwdriver combination tool that can raise the efficiency.

The technical solution adopted in the utility model is as follows:

This quick screwdriver combination tool, comprise knife bar and with the handle of a knife at its rear portion, in order to save the mounting or dismounting screw time, avoid in use screwdriver and then convolution to raise the efficiency, described handle of a knife afterbody is provided with spherical handle of a knife tail, and this spherical handle of a knife tail is bearing in the knife bar end.

This quick screwdriver combination tool can adopt Combined cutter arbor, and described knife bar comprises cutter head and cutter spindle, and the end of described cutter head is outer six square shafts, and two faces of Arbitrary Relative are provided with blind hole, and spring and ball are housed in blind hole; Described cutter spindle front end correspondence arranges interior hexagonal hole, and six faces of interior hexagonal hole are provided with locating groove, with the outer set spring ball corresponding matching of relative two faces of six square shafts of described cutter head end, makes cutter head be connected the location with cutter spindle.

The place, cutter spindle end circular shaft caster bed rank of described knife bar is provided with pressure bearing, the described spherical handle of a knife tail of pressure bearing upper support.Spherical cutter tailspin turns flexibly in use, and the dynamics size is easy to control.

In order to increase turning moment with laborsaving, can on described handle of a knife and cutter spindle, aperture be set, insert the laborsaving bar that another equipment is used when needing, rotate laborsaving bar and can increase turning moment and reach the labour-saving purpose.

This instrument can be equipped with serial driver bit, when the mounting or dismounting screw, can select connection cutter heads different in series according to the screw size.Cutter head can insert hexagonal hole in handle of a knife by any direction, facilitates the knife bar quick-replaceable.

Described handle of a knife outer shaft sleeve is decorated has decorative pattern in case the rubber insulation sleeve that on-slip is taken off.Described knife bar overcoat has the thermoplastic insulation tube.When low-voltage live line work, both all can play the insulation protection effect.

This quick screwdriver combination tool also can adopt single knife bar, directly at place, knife bar end circular shaft caster bed rank, pressure bearing, the described spherical handle of a knife tail of pressure bearing upper support are set.Also can save the mounting or dismounting screw time, avoid screwdriver and then to circle round to raise the efficiency.

This quick screwdriver combination tool is rational in infrastructure, it is firm to connect, easy to use, can save the mounting or dismounting screw time, and flog a dead horse when avoiding repeatedly afterburning rotation screw cutter, time saving and energy saving, can raise the efficiency, and can according to actual needs, select flexibly the different cutter heads in series, being suitable for power industry or other industry loading and unloading screw and using, is also the indispensable instrument that facilitates of daily life.

The specific embodiment

Introduce embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment 1

As shown in Figure 1, this quick screwdriver combination tool is divided into knife bar 1 and handle of a knife 2 two parts of one are inlayed at the rear portion.

As shown in Figure 2, knife bar 1 comprises the circular spindle nose 13 of cutter head 11, cutter spindle 12 and afterbody step.The outer six square shaft 11a of the afterbody of cutter head 11, two faces of Arbitrary Relative are provided with blind hole, and spring and ball 11b are housed in blind hole; Cutter spindle 12 is the steel construction axle, the one end has interior hexagonal hole 12a, six faces of interior hexagonal hole 12a are set position draw-in groove 12b, use with spring and ball 11b corresponding matching that outer six relative two faces of square shaft head 11a of the afterbody of cutter head 11 are set, cutter head 11 and cutter spindle 12 are both located, and the outer six square shaft 11a of cutter head 11 and the interior hexagonal hole 12a of cutter spindle 12 are connected in use.It is convenient that cutter head 11 inserts, changes.
