Abstract
The invention discloses a combination wrench for safely dismounting a handheld electric tool. Because a semicircular raised head is arranged at one end of a wrench body and a square sleeving opening is arranged in the semicircular raised head, the combination wrench is characterized in that: when a circular saw blade, a cutting blade, a grinding blade and other working devices used by the handheld electric tool are dismounted, a rectangular sleeving opening is directly sleeved into a round locknut rectangular sleeving head at the end part of a worm of the handheld electric tool, force can be added when the wrench body is pulled, and the sleeving opening of the wrench body cannot be distorted and skid easily after force application. Also, because a wrench inserting opening is arranged at the other end of the wrench body, the combination wrench is characterized in that: when the circular saw blade, the cutting blade, the grinding blade and other working devices used by the handheld electric tool are dismounted, the wrench inserting opening is directly inserted into a sleeve gasket inserting opening wrench groove at the end part of the worm of the handheld electric tool, and the worm of the handheld electric tool can be forcibly stopped from rotating.
Description
Technical fieldThe present invention relates to electric hand tool, directly relate to electric hand tool safety dismounting combination wrench, be specially adapted to round saw blade, cutting blade, abrasive disc and on electric hand tool, reinforce with dismounting and use.
Background technologyIn civil engineering, water, electric installation and the decorative engineering and other occasion of construction site, often use some electric hand tools.Electric hand tool commonly used has electric hand drill, electric hammer, percussion drill, portable emery wheel, electric screw driver, electric wrench, hand-held carpenter's plane, hand-held electric saw for woodworking, hand-held cutting machine, hand-held angle grinding machine etc.Though all kinds of electric hand tool shapes, purposes are different, their composition is similar, all partly is made up of miniature motor, workpiece, protective cover, hand-held handle, power switch, electric wire, plug etc.Therefore all have many general character in each part.Existing electric hand tool volume is little, power big, be convenient to move and carry, and is adopted by people are extensive always.But in long-term the use; Though people find that also existing electric hand tool volume is little; Power is big; Outside being convenient to move and carrying; But changing round saw blade; Cutting blade; Also there is the certain drawback that is not overcome when abrasive disc and other device work: when changing round saw blade by people; Cutting blade; When abrasive disc and other device work; Certainly will to round saw blade will be pressed solidly; Cutting blade; After unclamping, could realize the locking nut of abrasive disc and other device work changing; When the spanner and the template socket spanner that use the end to have two protruding bolt heads firmly turn the locking nut that has eyelet; The end has spanner and the template socket spanner of two protruding bolt heads because overexertion; Easy meeting is distorted spanner end two protruding bolt heads and is skidded; The template socket spanner socket mouth that rises; Skid because distorting has appearred in spanner end two protruding bolt heads; The socket mouth that rises has appearred in template socket spanner, is difficult for realizing when turning the locking nut that has eyelet once more.
Summary of the inventionThe object of the invention will provide a kind of electric hand tool safety dismounting combination wrench exactly; It can solve effectively: when changing round saw blade; Cutting blade; When abrasive disc and other device work; Certainly will to round saw blade will be pressed solidly; Cutting blade; After unclamping, could realize the locking nut of abrasive disc and other device work changing; When the spanner and the template socket spanner that use the end to have two protruding bolt heads firmly turn the locking nut that has eyelet; The end has spanner and the template socket spanner of two protruding bolt heads because overexertion; Easy meeting is distorted spanner end two protruding bolt heads and is skidded; The template socket spanner socket mouth that rises; Skid because distorting has appearred in spanner end two protruding bolt heads; The socket mouth that rises has appearred in template socket spanner, is difficult for the drawback that realizes when turning the locking nut that has eyelet once more.
The objective of the invention is to realize like this: electric hand tool safety dismounting combination wrench; Has wrench body; Said wrench body one end is provided with semi-circular plush copper; The square running-on is set in the semi-circular plush copper; The wrench body other end is provided with the spanner socket; Spanner socket side is provided with hanging hole, and middle part, spanner socket upper end is provided with magnetite.
The present invention is provided with semi-circular plush copper, the side of setting in the semi-circular plush copper owing to having adopted at wrench body one end
The jacket mouth, its characteristics are: when the employed round saw blade of dismounting electric hand tool, cutting blade, abrasive disc
When reaching other device work; The square running-on directly can be inserted in the round locking nut rectangle of electric hand tool worm screw end pullover on; Can realize can be afterburning when wrench body is pulled, and can realize again can not occurring owing to wrench body running-on after exerting oneself is prone to distort and skid.
The present invention is provided with the spanner socket owing to having adopted at the wrench body other end again; Its characteristics are: when the employed round saw blade of dismounting electric hand tool, cutting blade, abrasive disc and other device work; The spanner socket directly can be inserted the sleeve gasket socket spanner groove of electric hand tool worm screw end, can realize that ending the electric hand tool worm screw does not by force surely rotate.
Also owing to adopted in spanner socket middle part magnetite is set, its characteristics are in the present invention: when work finishes, for anti-other spanner bulk storage with lose, also can be with on other spanner absorption and the magnetite.
Description of drawingsAccompanying drawing is the structure principle chart of electric hand tool safety dismounting combination wrench of the present invention, and the present invention is further illustrated below in conjunction with accompanying drawing.
The specific embodimentAccompanying drawing shows structure of the present invention, and wrench body 1 one ends are provided with semi-circular plush copper 2,
In the semi-circular plush copper 2 square running-on 3 is set, wrench body 1 other end is provided with spanner socket 4, and spanner is inserted
The oral-lateral end is provided with hanging hole 5, and middle part, spanner socket 4 upper end is provided with magnetite 6.
Use of the present invention is: when the employed round saw blade of dismounting electric hand tool, cutting blade, abrasive disc and other device work; Wrench body 1 socket 4 that the end can be had the spanner socket inserts in the electric hand tool worm screw sockets and (indicates), and then is inserted in the wrench body 1 square running-on 3 that another end has a spanner socket that special locking nut square pullover 7 is interior can realize back-outing and be screwed into the square locking nut.
