Abstract
The invention discloses a foldable and portable electric wrench. A main body of the foldable and portable electric wrench is an electric wrench, wherein an output shaft, a ratchet shaft, a ratchet wheel, a motor shaft and a motor phase are successively arranged in the electric wrench from front to back; a battery clamp is arranged at the rear end of the motor; a battery cover is arranged on the battery clamp; a handle of the electric wrench is connected with the electric wrench main body through a circular movable hinge; a switch is arranged on the wrench; non-skid rubber is arranged on the surfaces of two sides of the wrench. The foldable and portable electric wrench has the advantages that the electric wrench is simple in structure, low in cost, convenient to use and carry, the handle is connected with the electric wrench through the circular hinge, the handle can be folded under the condition that the electric wrench is not used, the space is reduced, the electric wrench is convenient to carry, the electric wrench can be operated by only unfolding the handle under the condition that the electric wrench is used, the switch adopts a structure sunken in the handle, the handle can be conveniently folded, and the switch is not influenced.
Description
Technical field
The present invention relates to field of power tools, particularly a kind of foldable portable electric wrench.
Background technology
Electric wrench is exactly the spanner with power supply or battery as power, is that one kind tightens high intensity spiral shell
The instrument of bolt, is called high-strength bolt rifle.It is broadly divided into impact wrench, torsion cut spanner, determine moment of torsion
Spanner, corner spanner, angular spanner.Electric wrench is mainly used in Steel Structure Installation industry,
Special to install steel structure high strength bolt, high-strength bolt is for connection to steel construction contact, leads to
It is often occur with the mode of Bolt.General will first just tightly again for the fastening of high-strength bolt
It is tight eventually, and often step is required for strict torque demand.High-strength bolts first tight and
Tightly must all use constant torque wrench eventually. therefore various electric wrenches are exactly for various fastenings need
Come.Electric torsional shearing wrench exactly turns round as its name suggests the indispensable work for cutting Flos Mume hook bolt tightening operation
Tool, helps you to fill, nut, nut are torn open, while screw-down torque can be controlled relatively accurately.Profit
Determine moment of torsion with bolt, when spanner reaches certain moment of torsion by cut off the wabbler part of bolt,
Its torque precision and axial tension are to determine moment of torsion v-notch to ensure by bolt.Dismounting is turned round
Torque is big, more insure reliable than manual.It is convenient, attractive in appearance, practical, be easy to onboard.Extensively
The general construction operation for facilities such as steel structure bridge, Factory Building, generating equipments.
Electric wrench complex structure in life, volume is larger, inconvenient to carry, manufacturing cost
It is higher.
The content of the invention
It is an object of the invention to provide a kind of simple structure, simple operation, easy to carry, cost
Relatively low foldable portable electric wrench.
The technical solution used in the present invention is：
A kind of foldable portable electric wrench, main body is electric wrench, and its innovative point is：Institute
State electric wrench interior forward end and be provided with output shaft, the output shaft is connected with the front end of ratchet shaft
Connect, the ratchet shaft is provided with ratchet, the rear end of the ratchet shaft is axially connected with motor, institute
State motor shaft to be connected with motor, the rear end of the motor is provided with battery folders, the battery folders
Top is provided with battery cover, the spanner of the electric wrench by circular hinges with it is electronic
Wrench body is connected, and the spanner is provided with switch, and the both side surface of the spanner is provided with anti-
Sliding rubber.
Further, the motor is DC micro-motor.
Further, in the recessed handle of the switch.
Beneficial effects of the present invention are as follows：
It is of the invention to have the advantages that simple structure, cost are relatively low, easy to use, be convenient for carrying,
Handle is connected by circular hinges with electric wrench, can be in the case of not use by handle
Fold, reduce space, be convenient for carrying；And pulling handle is only being needed in the case of use
Just can operate；Switch so can folded conveniently using the structure in recessed handle, no
Have influence on switch.
Description of the drawings
The present invention is described in further details with reference to the accompanying drawings and detailed description.
Fig. 1 is schematic structural view of the invention.
Specific embodiment
A kind of foldable portable electric wrench as shown in Figure 1, main body is electric wrench 1, institute
State the interior forward end of electric wrench 1 and be provided with output shaft 2, before the output shaft 2 and ratchet shaft 3
End is connected, and the ratchet shaft 3 is provided with ratchet 4, the rear end of the ratchet shaft 3 and motor
To connection, the motor shaft 5 is connected axle 5 with motor 6, and the rear end of the motor 6 is provided with
Battery folders 7, the top of the battery folders 7 is provided with battery cover 8, the electric wrench 1
Spanner 9 is connected by circular hinges 10 with electric wrench main body, the spanner 9
Switch 11 is provided with, the both side surface of the spanner 9 is provided with anti-slip rubber 12.
The present invention operation principle be：
Handle 9 is connected by circular hinges 10 with electric wrench 1, can not used
In the case of handle is folded, reduce space, be convenient for carrying；And will in the case of use,
Only need pulling handle 9 just can operate；Switch 11 using the structure in recessed handle so
Can conveniently fold, not interfere with switch, using battery folders 7, it is possible to use battery, make
With convenient, it is not necessary to find power supply, it is adapted to more occasions.
The above is the preferred embodiment of the present invention, it is impossible to the power of the present invention is limited with this
Sharp scope.It should be pointed out that for those skilled in the art, to the present invention
Technical scheme modify or equivalent, without departure from protection scope of the present invention.
