Abstract
The invention discloses an electric wrench comprising a wrench body and a handle. The head of the wrench body is a fixed jaw or moving jaw. The end of the handle is externally provided with a power charge interface. A battery and a reducer motor are installed in the handle. A switch is disposed between the battery and the reducer motor and comprises a positive button and a reverse button. The rotating shaft end of the reducer motor is connected with a drive gear which meshes with an intermediate gear. A screw and a spur gear are disposed inside the head of the wrench body. The intermediate gear meshes with the spur gear. The spur gear is fixed inside the head of the wrench body through a shaft. The spur gear drives the screw which drives the moving jaw. The electric wrench has the advantages that through the application of gear reduction drive, the problem that manually adjusting openness of the jaw is less accurate is solved effectively and safety is improved; the electric wrench is quite convenient to use in small space; the external power charge interface allows for timely charge; when out of power, the electric wrench can be used manually.
Description
Technical field
The present invention relates to a kind of electric wrench.
Background technology
Spanner is a kind of conventional electric tool, adopts the aperture of manual mode adjusting jaw, relatively effort.For compare little place, space, hand is not easy to enter the nut of less Space adjustment spanner especially, generally will regulate in advance, so adjusting jaw aperture is not too accurate, governing speed is slow again.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The object of this invention is to provide the electric wrench that a kind of adjusting function is good.
The technical solution used in the present invention is:
A kind of electric wrench, comprise wrench body and handle, described wrench body head is regular jaw and moving jaw, described handle end external power charging socket, battery and reducing motor are installed in described handle, between described battery and reducing motor, be provided with switch, described switch comprises forward button and reverse button, described reducing motor rotating shaft end connection for transmission gear, described travelling gear and idler gear engagement, in described wrench body head, be provided with screw rod and spur gear, described idler gear and spur gear engagement, described spur gear is fixed in wrench body head by axle, described spur gear drive screw, described screw drive moving jaw.
Described travelling gear and idler gear are bevel gear.
Described wrench body head is provided with knob that can manual adjustments screw rod.
Beneficial effect of the present invention: electric wrench of the present invention, adopt gear reduction transmission, efficiently solve manual adjustments span of jaw problem not too accurately, increased security, while running into the too little situation in space, become very convenient, external power charging socket can charge in time, does not have electric time, can adopt manual mode to use spanner.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, wrench body, 2, handle, 3, regular jaw, 4, moving jaw, 5, power source charges socket, 6, battery, 7, reducing motor, 8, knob, 9, forward button, 10, reverse button, 11, travelling gear, 12, idler gear, 13, screw rod, 14, spur gear, 15, axle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As shown in Figure 1, a kind of electric wrench of the present invention, comprise wrench body 1 and handle 2, wrench body 1 head is regular jaw 3 and moving jaw 4, handle 2 end external power charging sockets 5, battery 6 and reducing motor 7 are installed in handle 2, between battery 6 and reducing motor 7, be provided with switch, switch comprises forward button 9 and reverse button 10, reducing motor 7 rotating shaft end connection for transmission gears 11, travelling gear 11 and idler gear 12 engagements, in wrench body 1 head, be provided with screw rod 13 and spur gear 14, idler gear 12 and spur gear 14 engagements, spur gear 14 is fixed in wrench body 1 head by axle 15, spur gear 14 drive screws 13, screw rod 13 drives moving jaw 4, travelling gear 11 and idler gear 12 are bevel gear, wrench body 1 head is provided with knob 8 that can manual adjustments screw rod.
Electric wrench of the present invention, adopt gear reduction transmission, efficiently solve manual adjustments span of jaw problem not too accurately, increased security, while running into the too little situation in space, become very convenient, external power charging socket 5 can charge in time, does not have electric time, can adopt manual mode to use spanner.
