Abstract

The utility model provides an antistatic screwdriver. The antistatic screwdriver comprises a screwdriver part (10) and an antistatic part (20) which is connected with the screwdriver part (10), wherein the antistatic part (20) comprises a connecting body (21); and the connecting body (21) is provided with a contacting part (21a) which is positioned on the outer surface of the screwdriver part (10). According to the antistatic screwdriver, a wired antistatic wrist strap is combined with the screwdriver, and a hand can naturally contact the contacting part positioned on the screwdriver part by means of the screwdriver when the antistatic screwdriver is operated, so that the static electricity is released, and the problems that the wired antistatic wrist strap is inconvenient to carry and is easy to left over during operation are effectively solved.

Description

The antistatic screwdriver

Technical field

The utility model relates to the antistatic field, in particular to a kind of antistatic screwdriver.

Background technology

Present stage, the extensive use in working environments such as production line and machine room of antistatic bracelet, according to the difference of operation principle, it can be divided into two kinds of wired formula and wireless type antistatic bracelets substantially.Wherein, because wireless type electrostatic discharge bracelet is directly in aerial discharge, and required electrostatic potential is too high during dissipation static, has reached more than the 1500V, so it is not suitable for electron trade; And wired formula static bracelet is very suitable among the electron trade, just be not easy to carry, at work, if forget or lose, just can influence work.

The utility model content

The utility model aims to provide a kind of antistatic screwdriver esy to use, safe and reliable, solves wired antistatic bracelet and is not easy to carry the problem of forgeing easily at work.

The utility model provides a kind of antistatic screwdriver, comprises screwdriver portion and coupled antistatic portion, and antistatic portion comprises connector, and connector has the contact site that is positioned on the screwdriver portion outer surface.

Further, screwdriver portion comprises screwdriver rod and coupled handle.

Further, antistatic portion also comprises lead and metal holder; Connector places handle; First end of lead is connected with connector, and second end of lead is connected with metal holder.

Further, contact site comprises one or more contact that is positioned at the handle outer surface.

Further, connector and screwdriver rod are in the handle internal insulation.

According to the utility model antistatic screwdriver; Effectively wired antistatic bracelet and screwdriver are combined, during operation, as long as use this screwdriver; Hand will natural contact be positioned at the contact site in the screwdriver portion; Thereby release electrostatic has effectively solved wired antistatic bracelet and has been not easy to carry the problem of forgeing easily at work.

Description of drawings

The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:

Fig. 1 is the structural representation according to the antistatic screwdriver of the utility model.

The specific embodiment

Below with reference to accompanying drawing and combine embodiment to specify the utility model.

As shown in Figure 1, according to the antistatic screwdriver of the utility model, comprise screwdriver portion 10 and coupled antistatic portion 20; Antistatic portion 20 comprises connector 21; Connector 21 is wedge shape, is connected with screwdriver portion 10, and connector 21 has the contact site 21a that is positioned on screwdriver portion 10 outer surfaces.Effectively wired antistatic bracelet and screwdriver are combined, during operation, as long as use this screwdriver, hand will natural contact be positioned at the contact site 21a in the screwdriver portion 10, thus release electrostatic.

Screwdriver portion 10 comprises screwdriver rod 11 and coupled handle 12.

Antistatic portion 20 also comprises lead 22 and metal holder 23, and connector 21 places handle 12, and first end of lead 22 is connected with connector 21, and second end of lead 22 is connected with metal holder 23.During use, metal holder 23 is clipped in the earthing pole in the working environment, static is introduced the earth the most at last.

Contact site 21a comprises one or more contact that is positioned at handle 12 outer surfaces, and contact is a conductor, is evenly distributed on the outer surface of handle, when using screwdriver, when holding handle, touches the contact that is positioned on the handle naturally, thereby discharges the static electricity on human body.

Connector 21 and screwdriver rod 11 prevent that the static of human body directly is delivered to electronic device through screwdriver rod 11, thereby cause damage in handle 12 internal insulation.

From above description, can find out that the utility model the above embodiments have realized following technique effect:

According to the utility model antistatic screwdriver, effectively wired antistatic bracelet and screwdriver are combined, during operation; As long as use this screwdriver, hand will natural contact be positioned at the contact site in the screwdriver portion, thus release electrostatic; Effectively having solved wired antistatic bracelet is not easy to carry; The problem of forgeing easily at work need not the extra antistatic tool of wearing, and improves the comfortableness and the security of work.

The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
