Loop is formed between shell tail end and shell tail end and with metal threaded tail cap, reversing switch 21.The galvanic circle reliability, structure letter
It is single, will not be as prior art：Because oppress spring in battery cathode disappear or rotten rust and cause to connect with battery
Touch bad.Because in the preferred embodiment, if use time one is grown, oppressing after the elasticity at battery two ends dies down, as long as
The metal threaded tail cap is tightened further.Function slot 231 is provided with the metal threaded tail cap 23, the function is inserted
Afterbody LED is inserted with optionally in groove 231, the afterbody LED is electrically connected with the reversing switch 21.The tail
Portion's LED can play an indicative function, point out the operator screwdriver in work.Certainly, in function slot 231 also
Other functors, such as MP3 player etc. can be patched.
Auto-manual screwdriver described in first embodiment is provided with preposition LED, the preposition LED include pcb board 81,
LED 82 and LED switch 83, the LED switch 83 are arranged between the shift knob 22 and the screwdriver bit 1 simultaneously
And the button of LED switch 83 protrudes from the shell wall of the shell 2, the pcb board 81 is fixed on the convex of the bearing block 7
On the outside of platform 71, the LED 82 be arranged on pcb board 81 and the LED 82 lamp holder towards screwdriver bit 1, the PCB
Conductor wire is connected between plate 81 and LED switch 83.The second embodiment that Fig. 6 is disclosed, and unlike first embodiment, institute
State after LED switch 83 is arranged at the reversing switch 21 and away from the screwdriver bit 1.Likewise, the in Fig. 8 the 3rd is real
Apply example LED switch 83 be also disposed at reversing switch 21 after.The setting of preposition LED is very important, and makes operator
Using the situation that working region can be seen when screwdriver where light is bad.In the present invention, the pcb board 81 and with
Its connected conductor wire can be substituted by flexible circuit board.
In electric model, the motor 3 drives support frame as described above 6 to rotate to the auto-manual screwdriver of the present invention, described
Pin 8 drives the output shaft 5 and screwdriver bit 1 to rotate under the driving effect of support frame as described above 6；In manual mode, in institute
State under 1 rotation status of screwdriver bit, the pin 8 is connected between the straightway 522 of the output shaft 5 and bearing block 7, it is described defeated
Shaft 5, bearing block 7, pin 8 and housing are relatively fixed.
Specially：Under electric model state, select to tighten or remove by the rotating of 21 regulation motor 3 of reversing switch
Screw, 21 motor 3 of reversing switch work, and the motor shaft of motor drives bracing frame 6 to rotate, and the adjutage 61 of bracing frame 6 drives
Dynamic pin 8, pin 8 fasten the region of the 522 nearly arc section of straightway of output shaft 5 and drive output shaft 5 to rotate, specifically, adjutage
The 61 pairs of pins 8 have circumference to active force, as pin 8 is with diameter greater than the distance between arc section and bearing block, so the work
Output shaft 5 is acted on by pin firmly, the output shaft 5 is final to drive screwdriver bit rotation to be operated.
Under manual mode state, when motor 3 does not work or under accurate operation requirement operating mode, directly tightened manually or
Screw is removed, during 1 rotary screw of screwdriver bit, screwdriver bit has active force to output shaft 5, and output shaft 5 can produce a bit of
Swing offset causes pin 8 to fasten straightway in output shaft 5 in the angle that bearing block is formed.Due to arc section 521 and bearing
Diameter of the distance between the seat 7 less than pin 8, so output shaft 5 can produce active force to pin when rotating, is made by straightway 522
For pin, the active force being subject to is sold towards bearing block 7, now under the active force of output shaft, output shaft, pin and bearing block are mutual
Fasten and be relatively fixed, as bearing block 7 and shell 2 are fixed, so output shaft, pin, bearing block, shell and screwdriver bit phase
To fixation, now screwdriver is consistent with normal screws batch using method.
