Abstract

A high-efficient rotary screw driver has the greatest advantage that a screw can be rotated continuously without need of changing hands. The screw driver, similar to a letter ''Z'' in appearance, comprises a tool-bar, a pressing handle, a rotary handle and a main body. The rotary handle runs parallel with the tool-bar and has a certain distance, which increases torque greatly; the tool-bar is detachable, so the user can install manifold or crosshead tool-bar according to specific requirements. When the utility model is used, two hands hold the pressing handle and the rotary handle respectively, the pressing handle puts vertical pressure on the rotary handle, while the rotary handle puts rotary force on the screw; two kinds of forces are shared with two hands, which greatly reduces the feeling of fatigue of single-hand operation. The utility model has the advantages of saving both time and labor, enhancing work efficiency, and reducing labor intensity, especially suitable for the operation of a large quantity of screws. The utility model is a novel screw driver with a practical value.

Description

Efficiently shake the formula screwdriver

Technical field:

The utility model belongs to hand-operated tools, relates in particular to a kind of formula screwdriver that efficiently shakes.

Background technology:

Though known various screwdriver different sizes, but structure is the same substantially, promptly is made up of knife bar and handle, and this structure has three defectives: a screwdriver when being to use can not rotate continuously, because hand can only turn an angle, the ability of need constantly changing hands complete operation; The 2nd, turning moment is less, is difficult to turn tighter screw; The 3rd, in the tighten the screws nail process, need simultaneously it to be applied two kinds of power, a kind of is revolving force, another kind is a pressure at right angle, and these two kinds of power are all born by a hand of handle, time one length is easy to feel tired.

Summary of the invention:

The technical problem that solves: in order to solve above-mentioned deficiency, the utility model provides a kind of formula screwdriver that efficiently shakes, and its twisting moment increases greatly, and main is to follow closely by uninterruptedly continuous rotation screw, and operate and not only save time, and also easily laborsaving.

The technical scheme that adopts: outer appearnce of the present utility model is like letter " Z ", and main body is made up of knife bar, pressure handle, rocking handle and trunk.One holds pressure handle and holds out against screw during use, and the another hand shakes rocking handle continuously, can be screwed into fast or the screw of back-outing.In addition, knife bar part of the present utility model is detachable, and the user can install " one " prefix or " ten " prefix knife bar as required.

Beneficial effect: use the utility model operation, time saving and energy saving, improved operating efficiency, reduced labour intensity, be particularly useful for the operation of a large amount of screws.

Description of drawings:

Fig. 1 is the utility model overall appearance schematic diagram.

Fig. 2 is the utility model knife bar structural representation when separating with trunk.

Fig. 3 is the utility model rocking handle cutaway view.

Each component names: rocking handle (1), pressure handle (2), baffle plate (3), inserted block (4), trunk (5), knife bar hole (6), square hole (7), trunk hole (8), screw (9), trunk tail (10), knife bar (11).

The specific embodiment:

As Fig. 1, shown in Figure 3, trunk (5) outer appearnce is like letter " Z ", and its two ends are with two handles respectively: rocking handle (1) and pressure handle (2), two handles can serve as that axle freely rotates with trunk (5).Trunk tail (10) is a screw hole, because the nut of screw (9) is bigger, thereby stops that rocking handle (1) breaks away from trunk (5).

As shown in Figure 2, knife bar (11) adopts with trunk (5) and removably connects, and the user can install different knife bars as required.After inserted block (4) inserts square hole (7), one piece of screw is inserted trunk hole (8) and screw in the knife bar hole (6), the size in trunk hole (8) just can be held this screw nut and partly enter, therefore nut can not exceed the surface of trunk (5), thereby can not influence contacting of pressure handle (2) and baffle plate (3).

As shown in Figure 1 and Figure 2, during use, one holds pressure handle (2) and withstands baffle plate (3), screw is applied pressure at right angle; The another hand shakes rocking handle (1) continuously screw is applied revolving force, can quick complete operation.

Claims

1. one kind is efficiently shaken the formula screwdriver, and main body is made up of rocking handle (1) and knife bar (11), it is characterized in that: rocking handle (1) is parallel with two straight lines at knife bar (11) place, and rocking handle (1) is used for screw is applied revolving force; Pressure handle (2) is used for screw is applied pressure at right angle.

2. the formula screwdriver that efficiently shakes according to claim 1 is characterized in that: rocking handle (1) and pressure handle (2) can serve as that axle freely rotates with trunk (5).

3. the formula screwdriver that efficiently shakes according to claim 1 is characterized in that: knife bar (11) and trunk (5) adopt and removably connect.
