Abstract
The utility model relates to a magnetic adjustable screwdriver which comprises a screwdriver rod, a screwdriver handle and a screw head. The inside of the screwdriver handle is hollow. A permanent magnet is arranged in the screwdriver handle. The magnetic adjustable screwdriver is characterized in that the permanent magnet is composed of a large cylinder and a small cylinder, one side of the small cylinder of the permanent magnet is connected with the handle on the tail portion of the screwdriver rod through a spring, one side of the large cylinder of the permanent magnet is connected with a push rod, an elastic button is arranged on the push rod, an elastic button hole is formed in the screwdriver rod handle, and a button is arranged on the elastic button hole. The screwdriver enables magnetism to exist on or be removed from the screwdriver rod and the screw head conveniently and quickly according to requirements. When the screwdriver rod and the screw head do not need magnetism, the magnetism is made to disappear immediately. A fixing screw sleeve convenient to detach is arranged at the screw head, so that screws are made to be more convenient and stable to detach and install. The magnetic screwdriver is lower in utilization cost, better in utilization effect, longer in service lift, simple in structure, and easy to popularize and use.
Description
Technical field
The utility model relates to a kind of maintenance tool commonly used, is specifically related to a kind of magnetic brace screw driver.
Background technology
In industrial production and daily life, screwdriver is all a kind of instrument that generally uses.Especially in assembling and maintenance field, screwdriver is a kind of indispensable instrument.But we scarcely possess magnetic function by daily screwdriver, often need to use the external force fixed screw during the turn of the screw, and during the dismounting screw, screw easily drops.Although the standby magnetic of some chasing tools is also arranged, all do not have controllability, when putting down screw or some and do not need the occasion of magnetic, be difficult to pull down magnet, the magnetic of screw rod is disappeared at once.Have some to utilize electromagnetic principle to make screw rod possess the screwdriver of magnetic, although effect is pretty good, also can substantially solve the problem of above existence, utilize electromagnetism power consumption large, need often to change battery, use cost is higher.The spiral shell head part of present screwdriver scarcely possesses the function of fixed screw in addition, and when dismounting or installation screw, the easy double swerve of screw makes troubles for dismounting or installation.How dismantling easily the screw fixture is also a problem demanding prompt solution, can make the spiral shell head satisfy different screws, enlarges the scope of application of screwdriver.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of above prior art, and a kind of magnetic brace screw driver has been proposed, this screwdriver can make the magnetic of screw rod and spiral shell head have or disappearing magnetism as required easily and efficiently, when screw rod and spiral shell head do not need magnetic, magnetic is disappeared at once, and Luo Touchu is provided with hold-down screw cover for convenience detach, makes the dismounting of screw and easier for installation, stable.And this magnetic screw driver use cost is lower, and result of use is better, longer service life, and simple in structure, be easy to apply.
The utility model scheme is achieved by the following technical measures:
A kind of magnetic brace screw driver, comprise screwdriver rod, screwdriver handle, spiral shell head, hollow in the screwdriver handle wherein, be provided with a block permanent magnet, its characteristics are that described permanent magnet is made of big column and two cylinders of small column, and permanent magnet small column one side is connected with screwdriver rod afterbody handle by spring, permanent magnet big column one side connects push rod, push rod is provided with the bullet button, and the screwdriver handle is provided with the bullet buttonhole, plays buttonhole and is provided with button.
Also be provided with a hold-down screw cover on above-described spiral shell head, the screwdriver rod front end is provided with external screw thread, and the hold-down screw cover is threaded connection with screwdriver rod.
The elastic force of the spring of described permanent magnet small column one side connection is greater than the magnetic force of permanent magnet and screwdriver rod afterbody in addition.
When wherein permanent magnet did not contact with the screwdriver rod afterbody, the distance that plays buttonhole on the bullet button on push rod and handle equaled the length of spring inactive state.
The length of described hold-down screw cover is greater than the length of spiral shell head in addition.
Described push rod passes screwdriver handle rear end in addition, and the push rod tail end is provided with and pushes away handle.
The beneficial effects of the utility model are: be provided with a block permanent magnet in the screwdriver handle, controlled by spring and push rod, when using, promote push rod, when permanent magnet contacted with the screwdriver rod afterbody, the bullet button on push rod sprang into the bullet buttonhole, fixing push rod, screwdriver rod and spiral shell head have magnetic force simultaneously, and adsorbable screw is stablized screw.When not needing magnetic force, press the button that plays on the screwdriver handle on buttonhole, the bullet button on push-rod handle is pressed back, and permanent magnet separates with the screwdriver rod afterbody under the spring force effect, and screwdriver rod and spiral shell head magnetic force disappear.This screwdriver can make the magnetic of screw rod and spiral shell head have or disappearing magnetism as required easily and efficiently.
Spiral shell head place is threaded connection a hold-down screw cover in addition, but hold-down screw during use makes the dismounting of screw and easier for installation, stable, backs out along screw thread, dismantles convenient.
And screwdriver described in the utility model need not electricity consumption, and use cost is lower, and result of use is better, longer service life, and simple in structure, be easy to apply.
Description of drawings
Fig. 1 is the structural representation of a kind of magnetic brace screw driver described in the utility model, and wherein 1 is the spiral shell head, and 2 is screwdriver rod, 3 is the screwdriver handle, and 4 for pushing away handle, and 5 is push rod, 6 is permanent magnet, 7 is spring, and 8 is the screwdriver rod afterbody, and 9 for playing buttonhole, 10 for playing button, 11 is button, and 12 is screw thread, and 13 is the hold-down screw cover.
The specific embodiment
In order to make the technical solution of the utility model clearer, the utility model is further described with embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of magnetic brace screw driver, comprise screwdriver rod 2, screwdriver handle 3, spiral shell head 1, wherein the interior hollow of screwdriver handle 3, be provided with a block permanent magnet 6, its characteristics are that described permanent magnet 6 is made of big column and two cylinders of small column, permanent magnet 6 small column one sides are connected with screwdriver rod afterbody 8 handles by spring 7, and permanent magnet 6 big column one sides connect push rod 5, and push rod 5 is provided with and plays button 10, screwdriver handle 3 is provided with and plays buttonhole 9, plays buttonhole 9 and is provided with button 11.
