Abstract
The invention belongs to the technical field of electric appliances and particularly relates to a driving device for a cordless electric wrench comprising a motor. One end of the motor is connected with a switch through leads. The switch is connected to a button and a battery clamp. The battery clamp can be clamped to a battery pack. The switch is connected with an indicator light through leads. The other end of the motor is connected to a motor gear connected with a gear case set. The gear case set is provided with a circular clamping groove, and is connected with a connecting rod. The driving device for the cordless electric wrench is large in torque, small in noise, high in efficiency, energy saving, long in service life, free of power cords during operation, free of electric shock, and more convenient to operate as compared with handheld alternating current electric tools.
Description
Technical field
The invention belongs to the electric tool technical field, relate in particular to a kind of drive unit of Ropeless electric spanner.
Background technology
Spanner is the instrument of tightening or unscrew screw, nut etc.Previously used spanner is a kind of installation and removal instrument commonly used.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner usually is shaped with clamp holder section and applies the external force shank and apply external force in the one or both ends of shank, just can twist bolt or nut and hold opening or the trepanning of bolt or nut.Apply external force along the screw thread rotation direction at shank during use, just can twist bolt or nut.This type of spanner needs artificial twisting, so very inconvenient when using on engineering.At present, used a kind of electric wrench, by alternating current, driven, this type of electric wrench has solved the problems referred to above, but this type of electric wrench need to use alternating current, so be that rope attachment plug is arranged, very inconvenient when in use, in the situation that do not have socket to use.So be badly in need of an energy in the situation that there is no the drive unit of the electric wrench that socket can also use.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of drive unit of Ropeless electric spanner is provided, its technical scheme is as follows:
A kind of drive unit of Ropeless electric spanner, comprise motor, it is characterized in that, an end of described motor is connected with switch by wire, described switch is connected with button, be connected with battery folder on described switch, described battery folder can be located on battery pack, and described switch is connected with indicator lamp by wire, the other end of described motor is connected with motor gear, described motor gear is connected with the gear-box group, offers annular slot on described gear-box group, and described gear-box group is connected with connecting rod.
Optimal way is, but described gear-box group is provided with the speed governing button of adjusting rotary speed.
Optimal way is that the front end of described connecting rod offers screw thread.
The drive unit of Ropeless electric spanner provided by the invention, when in use, whole drive unit all is arranged on the inside of fuselage cover, thereby can play the whole drive unit of protection.And the annular slot on the gear-box group can be socketed with the torsion cup, thereby controls the torque value of electric wrench.And at the front end of the connecting rod that is connected with the gear-box group, can be connected with chuck, can clamp rotary head or screw by chuck.Push switch, make motor connect battery pack, thereby make revolution, and the rotation of motor driving gear case group is rotated thereby make connecting rod drive chuck, finally rotary head or screw is screwed into desired location.
But gear-box group of the present invention is provided with the speed governing button of adjusting rotary speed.Can effectively control the rotating speed of chuck by the speed governing button, can take different rotating speeds according to different service conditions, in the hope of reaching best effect.
The front end of connecting rod of the present invention offers screw thread.Be threaded connection and can effectively strengthen connecting rod and be connected connection with chuck.
The present invention has high pulling torque, noise is little, efficiency is high, do not need power line when energy-conservation, long service life, work, there is no shock hazard, make operation more more convenient than hand-held AC electrical instrument.
Description of drawings
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of drive unit of Ropeless electric spanner, comprise motor 1, it is characterized in that, one end of described motor 1 is connected with switch 2 by wire, described switch 2 is connected with button 3, be connected with battery folder 4 on described switch 2, described battery folder 4 can be located on battery pack 5, described switch 2 is connected with indicator lamp 6 by wire, the other end of described motor 1 is connected with motor gear 7, described motor gear 7 is connected with gear-box group 8, offers annular slot 9 on described gear-box group 8, and described gear-box group 8 is connected with connecting rod 10.
Optimal way is, but described gear-box group 8 is provided with the speed governing button 11 of adjusting rotary speed.
Optimal way is that the front end of described connecting rod 10 offers screw thread.
The drive unit of Ropeless electric spanner provided by the invention, when in use, whole drive unit all is arranged on the inside of fuselage cover, thereby can play the whole drive unit of protection.And the annular slot on the gear-box group can be socketed with the torsion cup, thereby controls the torque value of electric wrench.And at the front end of the connecting rod that is connected with the gear-box group, can be connected with chuck, can clamp rotary head or screw by chuck.Push switch, make motor connect battery pack, thereby make revolution, and the rotation of motor driving gear case group is rotated thereby make connecting rod drive chuck, finally rotary head or screw is screwed into desired location.
Claims (3)
1. the drive unit of a Ropeless electric spanner, comprise motor, it is characterized in that, an end of described motor is connected with switch by wire, described switch is connected with button, be connected with battery folder on described switch, described battery folder can be located on battery pack, and described switch is connected with indicator lamp by wire, the other end of described motor is connected with motor gear, described motor gear is connected with the gear-box group, offers annular slot on described gear-box group, and described gear-box group is connected with connecting rod.
