Between connection angle it is adjustable, the bottom of oblique arm sets slider roller, and slider roller is located on incense coil inductance coil and props up disk
Fragrant inductance coil, slider roller is circumferentially rotated along incense coil inductance coil；The other end of turning arm sets the sliding block with tooth bar, rotation
The inside of pivoted arm is additionally provided with fixed gear, the axle center of the fixed gear and the axis coinciding of rotary shaft, and one end of tooth bar connects
Sliding block, middle part engagement fixed gear, the other end is fixedly connected with the inwall of turning arm.
During work, motor is rotated forward, and drives rotary shaft to rotate clockwise, so as to drive horizontally arranged turning arm
Also rotate together, because slider roller is slided along incense coil inductance coil, therefore, now slider roller is by incense coil inductor wire
The outermost end of circle is slided to innermost end, is slided radius and is tapered into, accordingly, because tooth bar also rotates in and then turning arm, because
This, during being engaged with fixed gear, moves so that the distance of sliding block to oblique arm is drawn with movable slider towards the direction of oblique arm
Closely, it is adjacent to state to ensure that slider roller is in all the time with incense coil inductance coil, it is ensured that both good contacts；When motor is anti-
Turn, foregoing advantages conversely, with slide radius become larger, sliding block is also gradually widened with the distance of oblique arm, with ensure slide roll
Wheel is in and is adjacent to state all the time with incense coil inductance coil, it is ensured that both good contacts；Thereby guarantee that and broadcast the good of broadcasting-quality.
Further preferred, the modulus of the wheel and rack is equal, and modulus is 0.5-1.3, and the number of teeth of tooth bar is gear
5 times -10 times of the number of teeth.
Further preferred, the number of teeth of the gear is 10, and the number of teeth of tooth bar is 84, and modulus is 0.8.
Further preferably the oblique arm is connected with turning arm by pitman, and turning arm is inserted in the pitman bottom
Fixing groove in, the jack on top insertion oblique arm top, rotary shaft connection between oblique arm and pitman.
The beneficial effects of the utility model are：Simple structure, sliding block movement is steady, and is engaged between rack and pinion
Power is enough to ensure that slider roller is contacted well with incense coil inductance coil so that the service life extension of emitter, working condition
Steadily, reliability is improved, and the beneficial effect that transmission accuracy is higher, is easy to renewal to repair is reached by machine driving, is worth market
Promote.
