Specific implementation mode
The present embodiment provides a kind of electric wrenches, as shown in Figures 1 to 4, including the first shell 1 and second shell that can fasten
Body 2, driving gear set, motor 3, battery 4, tumbler gear group, hex bolts fasten mold 5 and are opened and closed for controlling motor 3
Switch 6；First shell 1 and second shell 2 are including handle portion and for stretching into gap at the top of corridor roof and air hose
Work department, work department can decide length in its sole discretion according to the practical air hose degree in scene, and principle is constant；Driving gear set is arranged first
In the fixing groove of 1 work department of shell, including driving wheel 7, the first driven wheel 8, the transmission for connecting driving wheel 7 and the first driven wheel 8
Rotation axis 10 with 9 and 7 and first driven wheel 8 of fixed driving wheel；The both ends of rotation axis 10 are plugged in 1 He of first shell respectively
In the turn hole 11 of second shell 2；Motor 3 and battery 4 are arranged in the fixing groove of 2 handle portion of second shell, and motor 3 and battery
4 electrical connections；Tumbler gear group is arranged in the fixing groove of 2 work department of second shell；Tumbler gear group includes that setting is defeated in motor 3
The first bevel gear 12 on shaft and second bevel gear 13 coaxial with 12 Vertical Meshing of the first bevel gear and with driving wheel 7,
