Abstract
The utility model belongs to the technical field of electric tools, and particularly relates to a driving device of a wireless electric spanner. The driving device of the wireless electric spanner comprises a motor, a switch is connected to one end of the motor through wires, a button is connected with the switch, a battery clamp is connected to the switch, the battery clamp can be arranged on a battery pack in a clamped mode, the switch is connected with an indicator light through wires, a motor gear is connected to the other end of the motor, the motor gear is connected with a gear box set, an annular clamping groove is formed in the gear box set, and a connecting rod is connected to the gear box set. The driving device has the advantages of being large in torque, low in noise, high in efficiency, capable of saving energy, long in service life, free of power lines in the working process, free of shock hazards and more convenient to operate compared with a hand-held type alternating-current electric tool.
Description
Technical field
The utility model belongs to the electric tool technical field, relates 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 opening or trepanning that bolt or nut are held 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, driven by alternating current, 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 the drive unit of the electric wrench that does not have socket to use.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, and a kind of drive unit of Ropeless electric spanner is provided, and 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, on described gear-box group, offers annular slot, 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 the Ropeless electric spanner that the utility model provides, 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 control the torque value of electric wrench.And can be connected with chuck at the front end of the connecting rod be connected with the gear-box group, 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 to desired location.
But gear-box group described in the utility model 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 described in the utility model offers screw thread.Be threaded connection the connection that can effectively strengthen connecting rod and chuck.
The utlity model 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.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
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, on described gear-box group 8, offers annular slot 9, 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 the Ropeless electric spanner that the utility model provides, 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 control the torque value of electric wrench.And can be connected with chuck at the front end of the connecting rod be connected with the gear-box group, 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 to desired location.
