Description

A kind of magnetic attachment type screw driver

Technical field

The utility model relates to driver technology fields, and in particular to a kind of magnetic attachment type screw driver.

Background technique

Screwdriver is a kind of a kind of tool that fixed effect is reached for rotary fixing screw silk.Usually using screw It can all be disassembled from mechanical equipment or product there are many small parts such as screw when knife, since screw is small in size, quantity is more The loss of screw is thus easily caused when screwdriver dismounts screw.

Application No. is 201810478357.9 Chinese patents to disclose a kind of screwdriver for preventing part from losing, packet Include: handle, screw rod, driver bit and part adsorbent, the handle, screw rod and driver bit are successively fixed from top to bottom Connection, the part adsorbent include flexible fastening body and magnetic adsorbing block, and the flexible fastening body passes through the magnetic absorption Block, the maximum circumference size of the magnetic adsorbing block are less than the cross-sectional profiles size of the handle, the part absorption Body is set to any part of screwdriver.

Screwdriver in above-mentioned technical proposal is fixed on by being adsorbed the small parts such as screw using magnetic adsorbing block On screwdriver, the loss that not will cause small part when the screwdriver of part loss is prevented；In actual use, magnet is utilized Screw rod magnetization can be facilitated to the installation of screw, but the screwdriver after magnetizing prevents meeting and other irony works in tool box Tool, ferrous element are attached together, and on the one hand cause to need to clear up the tool being adsorbed on screwdriver, zero when taking out screwdriver Part can generate unnecessary magnetization after another aspect tool, part and magnetic bodies standing time are long, influence other tools, zero The normal use of part increases the use burden of user, and there are improvements for the prior art.

Utility model content

In order to solve the above technical problems, the utility model proposes a kind of magnetic attachment type screw drivers, by being clamped to spiral shell Magnet fixed sleeve on silk knife bar provides magnetic force for screwdriver rod, and magnet fixing sleeve is removed independent storage when not in use, is kept away Exempt to adsorb irony tool, part on screwdriver rod, in order to which user takes out screwdriver.

In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of magnetic attachment type screw driver includes screwdriver Bar and the knife handle being arranged on the screwdriver rod are removably connected with magnet fixed sleeve, the magnetic on the screwdriver rod Ferropexy set includes fixing seat and retaining sleeve, is fixedly installed permanent magnet in the fixing seat, the retaining sleeve and it is described forever Magnet is oppositely arranged the gripping channel to be formed and be passed through for the screwdriver handle, and the fixing sleeve is bonded with the screwdriver rod and sets It sets, the retaining sleeve slides setting along perpendicular to the screwdriver rod length direction, and the retaining sleeve is the irony that can be adsorbed Material.

The utility model is further arranged to: the V-shaped structure of retaining sleeve.

The utility model is further arranged to: the retaining sleeve v-angle is arranged in arc structure.

The utility model is further arranged to: the two sides of the fixing seat are extended with wing plate, wear on the wing plate and have penetrated cunning Bar is moved, the sliding bar is fixedly connected with the retaining sleeve.

The utility model is further arranged to: the sliding bar is made of nonmagnetic material.

The utility model is further arranged to: the fixing sleeve is provided with adsorbing plane far from the side of the retaining sleeve.

In conclusion the utility model has the effect that

1, when permanent magnet is adsorbed on screwdriver rod, magnetic field is formed on screwdriver rod, in order to which user passes through spiral shell Silk knife bar adsorbs the screw in screw hole or screw is put into screw hole；

2, tiny part is temporarily adsorbed in fixing seat by the adsorbing plane being arranged in fixing seat convenient for user, a side Face avoids small part from losing in user's operating process；On the other hand suitable part is chosen conveniently convenient for user；

3, the retaining sleeve of V-type setting can be adsorbed on screwdriver rod, convenient for the installation of magnet fixing sleeve, fixation and be torn open It removes.

Detailed description of the invention

It, below will be to embodiment or the prior art in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing needed in description is briefly described.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As depicted in figs. 1 and 2, a kind of magnetic attachment type screw driver includes screwdriver rod and is arranged on screwdriver rod Knife handle, is removably connected with magnet fixed sleeve on screwdriver rod, and magnet fixed sleeve includes fixing seat and retaining sleeve, in fixing seat It is fixedly installed permanent magnet, retaining sleeve and permanent magnet are oppositely arranged the gripping channel to be formed and be passed through for screwdriver handle, fixing sleeve Setting is bonded with screwdriver rod, retaining sleeve slides setting along perpendicular to screwdriver rod length direction, and retaining sleeve can be adsorbed Ferrous material.

Further, the V-shaped structure of retaining sleeve.

Further, retaining sleeve v-angle is arranged in arc structure.

Further, the two sides of fixing seat are extended with wing plate, wear on wing plate and have penetrated sliding bar, and sliding bar is fixed with retaining sleeve Connection.

Further, sliding bar is made of nonmagnetic material.

Further, fixing sleeve is provided with adsorbing plane far from the side of retaining sleeve.

It should be pointed out that for those of ordinary skill in the art, before not departing from the concept of the present invention It puts, various modifications and improvements can be made, and these are all within the protection scope of the present invention.
