Abstract

A screwdriver, belonging to the technical field of hand tools, comprises a quadrangular handle and a screwdriver body arranged at one end of the handle, and is characterized in that power arms are arranged on both symmetrical sides of the handle, and non-slip frosted structures are arranged on the symmetrical sides. The utility model has a simple structure, and the anti-slip friction structure provided on the handle can effectively prevent the phenomenon of slipping when exerting force. The setting of a power arm on the left and right can enhance the torque, and the power arm can be folded into the groove during normal use. , the same as a normal screwdriver. When you need to use more power, unfold the power arm, which can solve the disadvantages of lack of power and slow work of ordinary screwdrivers. The operation is simple, time-saving and labor-saving, and it plays a very good role in improving efficiency.

Description

a screwdriver

technical field

The utility model belongs to the technical field of hand tools, in particular to a screwdriver.

Background technique

Screwdrivers are often used in daily life to load and unload screws, and most of the screwdrivers sold on the market are composed of a handle and a rod connected to the handle. Users generally hold the handle with one hand and rotate the screwdriver to tighten or loosen the screws. operation, but this can only meet the screws that can be tightened or loosened with a small force. When encountering some difficult screws, this kind of ordinary screwdriver is a bit difficult, because most screwdrivers use the handle. The diameter is used as the power arm, so it usually takes a lot of effort to achieve good results, especially when encountering screws that need to be tightened or unscrewed, due to the lack of power arm, it not only takes a long time, but also Also need bigger strength, because hold handle for a long time, hand is easy to perspire, and the phenomenon of skidding when holding handle can occur, can't use strength well, brings inconvenience and limitation in use to the user.

Contents of the invention

Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a screwdriver capable of increasing the power arm.

The utility model is realized through the following technical solutions:

Said screwdriver comprises a quadrangular handle and a screwdriver body arranged at one end of the handle, and is characterized in that power arms are arranged on both symmetrical sides of the handle, and non-slip frosted structures are arranged on both symmetrical sides.

The screwdriver described above is characterized in that grooves are arranged symmetrically on the handle, and a power arm cooperating with the groove is embedded in the groove.

The screwdriver described above is characterized in that the groove is a longitudinal groove.

The utility model has a simple structure, and the anti-slip friction structure provided on the handle can effectively prevent the phenomenon of slipping when exerting force, and the setting of a power arm on the left and right can enhance the torsion force, and the power arm can be folded into the groove during normal use , the same as a normal screwdriver. When you need to use more force, unfold the power arm, which can solve the disadvantages of lack of power and slow work of ordinary screwdrivers. The operation is simple, time-saving and labor-saving, and it plays a very good role in improving efficiency.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the schematic diagram when the utility model is used.

In the figure, 1-handle, 2-driver body, 3-groove, 4-power arm, 5-anti-slip friction structure.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings of the description, and specific implementation methods will be given.

As shown in the figure, a screwdriver includes a quadrangular handle 1 and a screwdriver body 2, the screwdriver body 2 is fixedly arranged at one end of the handle 1, and longitudinal grooves 3 are arranged on both symmetrical sides of the handle 1, and the groove 3 The power arm 4 is embedded and used in conjunction with the power arm 4. The rotatable angle range of the power arm 4 is 0-90 degrees. At 0 degrees, the power arm 4 is folded in the groove, and the effect is the same as that of a general screwdriver. When the power is insufficient , the power arm 4 can be displayed at 90 degrees perpendicular to the handle 1, the power is greatly increased, the effect of labor saving is achieved, and the operation time is saved at the same time. Anti-slip friction structures 5 are provided on the other symmetrical sides of the handle 1 to prevent hand sweating When the item slips, the screw can be operated smoothly.

Claims (3)

1. bottle opener comprises four prismatic handles (1) and is arranged at the bottle opener body (2) of handle (1) one end that it is characterized in that the symmetrical both sides of said handle (1) are provided with power arm (4), symmetrical both sides are provided with anti-skidding frosted structure (5) in addition.

2. a kind of bottle opener according to claim 1 is characterized in that being symmetrical set on the said handle (1) groove (3), and interlocking is provided with the power arm (4) that is used with groove (3) in the groove (3).

3. a kind of bottle opener according to claim 1 and 2 is characterized in that described groove (3) is a cannelure.
