Description

Multifunctional screwdriver

The utility model relates to the multipurpose screwdriver of six combined integrated uses of crewdriver attachment.

Existing screwdriver has fixed and interchangeable two kinds.Fixed is that the awl bar that will have specific conehead is fixed on the awl handle, interchangeablely be meant the replaceable some coneheads of taper shank, when the former works, the user need have size dimension and all size is many screwdriver, when working, the latter need only change crewdriver attachment, therefore that supplies on the market often makes a small tool bag, uses inconvenience and operating efficiency not high.

The purpose of this utility model is that a kind of multipurpose screwdriver will be provided, and this screwdriver is the conversion conehead rapidly, and to adapt to the screw of straight trough or cross recess full range of sizes.

For realizing this purpose, this multipurpose screwdriver that the utility model proposes comprises conehead, awl bar, pivoted housing and awl handle.The rear end of awl bar links to each other with the awl handle, at the screwdriver middle part the six groove pivoted housings of depositing conehead is arranged.Six coneheads place in the pivoted housing with the awl bar, so that change conehead at any time.Control break-in parts are housed in the awl handle, and control assembly comprises break-in switch, limiting plate and limit to clamp, and control assembly makes the awl bar terminal gear teeth and spacing clamp chain by the control of break-in switch, thereby reaches the purpose of the positive and negative both direction rotation of control awl bar.

Because adopt such scheme, this screwdriver has been realized the conversion of positive and negative both direction, so that tighten or unclamp screw.Compare with existing screwdriver, not only convenient, and also practical.

Below in conjunction with example and accompanying drawing thereof the utility model is described further.

Fig. 1 is for reflecting the integrally-built profilograph of the multipurpose screwdriver that the utility model proposes.

Fig. 2 is a multipurpose screwdriver pivoted housing cross section view shown in Figure 1.

In Fig. 1, handgrip gum cover (1) is fixed on the awl handle (2), pedestal (3) and cushion rubber (4) support cone bar (15), break-in plate (5) and reed (6) are formed the break-in switch, constitute the control deviator with limiting plate (7), limit to clamp (8), and promptly the break-in switch moves forward and bores bar (15) the terminal gear teeth and lock mutually, but the screwdriver clockwise direction rotates, conversely, the break-in switch moves backward, and then screwdriver can counterclockwise move.Top cover (9), positioning reed (10), pivoted housing (11) and end cover (12) place awl bar, conehead outside, plus screw (14) is used for fixing the end cover (12) and pivoted housing (11), blanking cover (13) gets lodged in screw (14) recess, awl bar (15) has the groove interlocking with conehead (16) in the termination, along axis direction pulling awl bar, conehead can be drawn in (or release) pivoted housing.

Analyse and observe in the illustrated example at A-A, six grooves are arranged in the pivoted housing (11), having six different coneheads deposits in the pivoted housing (11), when changing conehead, as long as when holding handle (2) and inwardly spurring conehead (16) and place the position of pivoted housing (11), rotate pivoted housing then, can release another conehead and use.
