Description
Technical field
The invention belongs to hardware tool field, specially a kind of antioverloading electric screw driver.
Background technique
In terms of screwdriver is widely used in the installation and removal of mechanical equipment, it has also become the indispensable work of machinery field
Tool.With the development of science and technology, institute's mechanical equipment structure increasingly carrys out complicated, more and more finer, the used screw type of manufacture
Various, Today, most screwdriver is all fixed, or tighten by hand, it has not been convenient to the dismounting of screw, it is inefficient, and
Most of torques are non-adjustable, have and thread is caused to jump the danger of falling, it is therefore necessary to overload when preventing screw-driving of developing one kind
And the screwdriver of high reliablity.
Summary of the invention
The purpose of the present invention is in view of the above problems, providing a kind of antioverloading electric screw driver, it can be achieved that screwdriver is tightened
Torque is adjustable, can arbitrarily replace cutter head, meets a variety of occasion demands, screw is facilitated to dismount, compact-sized.
In order to achieve the above object, the technical solution adopted by the present invention is that: a kind of antioverloading electric screw driver, including shell,
Retarder is equipped in the shell, the retarder input terminal is connect with clutch, and the Clutch input shaft is equipped with input
Toothed disc, regulation handle；The shell lower end is equipped with handle, described interior equipped with motor, switch, power supply, charging head, the motor
Input shaft is engaged with input gear disk, and the motor, charging head, is electrically connected to a power source switch；The housing forward end, which is equipped with, to be fixed
Bar, the fixed link is interior to be equipped with drive rod, and described drive rod one end is connect with retarder output end, and the other end is equipped with adapter,
Driver bit is equipped in the adapter.
Further, the retarder includes the driving wheel, planetary gear and ring gear being meshed, and the planetary gear is equipped with
Rotatable planet carrier.
Further, steel ball is equipped between the Clutch input shaft and regulation handle.
Beneficial effects of the present invention: the steering of driver bit can be achieved, facilitate screw to dismount, and torque is adjustable, structure
It is compact.

Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing to the present invention into
Row detailed description, the description of this part be only it is exemplary and explanatory, should not have any limitation to protection scope of the present invention
Effect.
As shown in Figure 1, specific structure of the invention are as follows: a kind of antioverloading electric screw driver, including shell 1, the shell 1
Interior to be equipped with retarder 2,2 input terminal of retarder is connect with clutch 3, and 3 input shaft of clutch is equipped with input gear
Disk 31, regulation handle 32；1 lower end of shell is equipped with handle 4, described interior equipped with motor 41, switch 42, power supply 43, charging head
44,41 input shaft of motor is engaged with input gear disk 31, and the motor 41, charging head 44, is electrically connected with power supply 43 at switch 42
It connects；1 front end of shell is equipped with fixed link 5, and drive rod 51, described 51 one end of drive rod and deceleration are equipped in the fixed link 5
The connection of 2 output end of device, the other end are equipped with adapter 52, are equipped with driver bit 6 in the adapter 52.
Preferably, the retarder 2 includes driving wheel 21, planetary gear 22 and the ring gear 23 being meshed, the planetary gear
22 are equipped with rotatable planet carrier 24.
Preferably, steel ball 33 is equipped between 3 input shaft of clutch and regulation handle 32.
When specifically used, driver bit 6 required for installing on adapter 52, the positive and negative of motor can be realized by pressing switch 42
Turn that the release of screw can be realized and tighten, screw is facilitated to dismount；Regulation handle 32 is rotated, the friction on clutch 3 can be changed
Power, it is adjustable to can be realized torque, prevents from overloading compact-sized.
It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment for including a series of elements not only includes those elements, and
