Description

The flexible handle screwdriver

Technical field

The utility model relates to a kind of flexible handle screwdriver.

Background technology

Screwdriver is a kind of common tool, and its effect is to be used for the holding screw nail, and generally speaking, screwdriver includes knife bar and shank; Shank is to be used for hand to grip, and existing screwdriver shank structure is too single, if need bigger revolving force during holding screw; Then need hand that shank is held with a firm grip, the difficulty when increasing holding screw, the screwdriver that also has is provided with gelatinous layer at shank; With the frictional force between increase shank and the hand, but in some cases, still can't meet the demands.

Summary of the invention

Based on this, the utility model is to overcome the defective of prior art, and a kind of flexible handle screwdriver is provided, and the utility model is conversion as required, when needed bigger revolving force can be provided.

Its technical scheme is following:

A kind of flexible handle screwdriver comprises knife bar and shank, and shank is connected in the rear end of knife bar, and said shank comprises at least two movable handles, and movable handle is hinged on the rear end of said knife bar, and movable handle has deployed condition and collapse state.

Describe in the face of further technical scheme down:

Rear end at said knife bar is provided with pole socket, and said movable handle and pole socket are articulated and connected.

In deployed condition, said movable handle is vertical with said knife bar, and at collapse state, said movable handle is parallel with said knife bar.

Also include the button cap, at collapse state, the tail end of at least two movable handles fastens through the button cap.

Advantage or principle in the face of the aforementioned techniques scheme describes down:

1, because the shank of this screwdriver comprises the movable handle of at least two hinged settings, movable handle can rotate around pin joint, makes movable handle have and folds and launch two states; When each movable handle folded, each movable petioliform became complete shank, and this moment, this screwdriver was equivalent to traditional screwdriver; When each movable handle launches; Whole screwdriver forms the T font, and the arm of force during the screwdriver rotation is longer, and revolving force is bigger;

2, the rear end of knife bar is provided with pole socket, can be with more firm being arranged on the pole socket of movable handle, avoid the loosening or distortion of movable handle and influence is used.

The specific embodiment

Embodiment in the face of the utility model is elaborated down:

Like Fig. 1, shown in Figure 2, a kind of flexible handle screwdriver comprises knife bar 10 and shank 20; And shank 20 is connected in the rear end of knife bar 10; Said shank 20 comprises two movable handles 21, and movable handle 21 is hinged on the rear end of said knife bar 10, and movable handle 21 has deployed condition and collapse state.

Wherein, also include button cap 22, at collapse state, the tail end of two movable handles 21 fastens through button cap 22.Be provided with pole socket 11 in the rear end of said knife bar 10, said movable handle 21 is articulated and connected with pole socket 11.In deployed condition, said movable handle 21 is vertical with said knife bar 10, and at collapse state, said movable handle 21 is parallel with said knife bar 10.

Present embodiment has following advantage:

1, because the shank 20 of this screwdriver comprises the movable handle 21 of two hinged settings, movable handle 21 can rotate around pin joint, makes movable handle 21 have and folds and launch two states; When each movable handle 21 folded, each movable handle 21 formed complete shank 20, and this moment, this screwdriver was equivalent to traditional screwdriver; When each movable handle 21 launches; Whole screwdriver forms the T font, and the arm of force during the screwdriver rotation is longer, and revolving force is bigger;

2, the rear end of knife bar 10 is provided with pole socket 11, can be with movable handle 21 more firm being arranged on the pole socket 11, avoid the loosening or distortion of movable handle 21 and influence is used.

The above embodiment has only expressed the specific embodiment of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
