Abstract
The utility model discloses an electronic wrench comprising a wrench body and a handle, wherein the head portion of the wrench body is provided with a fixed jaw and a movable jaw, the end portion of the handle is externally connected with a power charging socket, a battery and a speed-reducing motor are arranged in the handle, a switch is disposed between the battery and the speed-reducing motor, the switch comprises a forward key and a reverse key, a rotating shaft end of the speed-reducing motor is connected with a transmission gear meshed with a middle gear, a screw rod and a spur gear are installed in the head portion of the wrench body, the middle gear is meshed with the spur gear, the spur gear is fixed in the head portion of the wrench body through a shaft, the spur gear drives the screw rod, and the screw rod drives the movable jaw. By means of gear speed-reducing transmission, the electronic wrench has the advantages of effectively solving the problem that the open degree of jaws is not accurate when adjusted manually, increasing safety, and being convenient under the condition of small space. Besides, the electronic wrench can be charged in time due to the externally-mounted power charging socket, and can be used in a manual way when electricity is not supplied.
Description
Technical field
The utility model relates to a kind of electric wrench.
Background technology
Spanner is a kind of electric tool commonly used, adopts the aperture of manual mode adjusting jaw, relatively effort.Special hand is not easy to enter the nut of less Space adjustment spanner, generally will regulate in advance for less place, space, so the 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.
