Abstract
The utility model relates to a machine tool, particularly a wrench. As a common machine tool, the wrench is an indispensable tool for production and maintenance in people's daily life. A conventional wrench is operated through manual labor to load and unload a corresponding nut, resulting in time and labor waste, and meanwhile, fastness is hard to be ensured during the nut reinforcement. The utility model provides the technical scheme that the wrench comprises a manual control panel, a fixing shaft, a motor, a power supply and a switching device, wherein the motor is arranged inside the fixing shaft, the motor is connected with the alveolus of the manual control panel, the power supply is arranged at one end of the fixing shaft and is connected with the motor through a circuit, and the switching device arranged on the power supply is used for controlling current output. Nut clamping grooves meeting national standards are formed on the manual control panel. The switching device has the function of a relay. Due to the adoption of the technical scheme, the structure is simple, and the manufacturing cost is low. The switching device is used for controlling the power supply to supply power to the motor so as to enable the motor to work. Therefore, the manual control panel is driven to rotate, and the purposes of dismounting and mounting are achieved.
Description
Affiliated technical field
The utility model relates to machine tool, relates to a kind of spanner of meter especially.
Background technology
Spanner is that daily people produce instrument indispensable in the maintenance as a kind of common machine tool.Existing wrench operated all is to implement by manpower, loads and unloads corresponding nut with this.Waste time and energy like this, when nut is reinforced, also be difficult for firmly simultaneously.
Summary of the invention
For solving the deficiencies in the prior art, this is novel to provide a kind of technical scheme, this scheme is: a kind of spanner, this spanner is made up of operation board, fixed axis, motor, power supply and switching device, motor is arranged in the fixed axis, and motor is connected with the operation board teeth groove, and power supply is arranged on fixed axis one end, be connected with motor by circuit, by the switching device control electric current output that is arranged on the power supply.Described operation board is provided with GB specifications of nuts draw-in groove.Described switching device has relay function.
The operation board that a plurality of GB standards are set that this is novel satisfies the needs of routine work.
The characteristics of this technical scheme from the above, this technical scheme is simple in structure, and is cheap.Power to motor by switching device control power supply, make machine operation, rotate, with this purpose that reaches dismounting and install thereby drive operation board.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model operation board.
1 is operation board among the figure, and 2 is fixed axis, the 3rd, and power supply, the 4th, motor, the 5th, switching device, the 6th, nut draw-in groove.
The specific embodiment
As shown in FIG.:
A kind of spanner, this spanner is made up of operation board (1), fixed axis (2), motor (4), power supply (3) and switching device (5), motor (4) is arranged in the fixed axis (2), motor (4) is connected with operation board (1) teeth groove, power supply (3) is arranged on fixed axis (2) one ends, be connected with motor (4) by circuit, be arranged on switching device (5) the control electric current output on the power supply (3).Described operation board (1) is provided with GB specifications of nuts draw-in groove (6).Described switching device (5) has relay function.
During use,, power supply (3) electric power is fed on the motor (4) by switching device (5) control because motor (4) is that teeth groove is connected with operation board (1), by motor (4) thus work make the rotation of operation board (1).Simultaneously according to need of work, by the relay function of switching device (5), the positive hour hands of motor (4) and operation board (1) are rotated or be rotated counterclockwise, thereby finish installation or removal.
Claims (3)
1. spanner, it is characterized in that: this spanner is made up of operation board, fixed axis, motor, power supply and switching device, motor is arranged in the fixed axis, motor is connected with the operation board teeth groove, power supply is arranged on fixed axis one end, be connected with motor by circuit, be arranged on the switching device control electric current output on the power supply.
2. spanner according to claim 1 is characterized in that: described operation board is provided with GB specifications of nuts draw-in groove.
