Abstract
The utility model discloses a miniature remote operating mechanism comprising a poking handle and an electric mechanism which is used for driving the poking handle to be poked in a reciprocating way. The electric mechanism comprises a motor with an output gear wheel, a poking wheel and a linkage gear wheel component. The linkage gear wheel component comprises a primary gear wheel which is fixedly arranged on a pin shaft, a secondary gear wheel which is slidably arranged on the pin shaft, a coil which is arranged on the primary gear wheel, a magnetic yoke which is arranged on the secondary gear wheel, returning springs which are used for pushing the secondary gear wheel to direction away from the primary gear wheel, and rolling beads which are arranged between the primary gear wheel and the secondary gear wheel. An adjoining surface, which adjoins the secondary gear wheel, of the primary gear wheel is provided with multiple position-specifying holes which are arranged in parallel with extension direction of the pin shaft. The rolling beads are arranged on the opening ends of the position-specifying holes. Each returning spring is arranged inside the corresponding position-specifying hole, and the external side ends of the returning springs are connected with the rolling beads in an abutting way so that the rolling beads protrude out of the adjoining surface, which is used for adjoining the secondary gear wheel, of the primary gear wheel. The miniature remote operating mechanism is reasonable and compact in structure and stable and reliable in performance.

Embodiment
(embodiment 1)
Fig. 1 to Fig. 2 has shown the first embodiment of the present utility model, and wherein Fig. 1 is a kind of perspective view of the present utility model; Fig. 2 is a kind of decomposing schematic representation of the mechanism of remote operation shown in Fig. 1.
The present embodiment is a kind of compact remote operating mechanism, sees shown in Fig. 1 and Fig. 2, comprises and dials handle 4 and dial for driving the motor drive mechanism 5 that handle is back and forth stirred; It is characterized in that: motor drive mechanism comprises the linkage gear assembly 54 of motor 52, thumb wheel 53 and interlock output gear and the thumb wheel with output gear 51, described motor drives thumb wheel reciprocating rotation by linkage gear assembly, and and then is driven and dialled handle reciprocating rotation by thumb wheel.
On described thumb wheel, be fixed with plate 55, the outboard end of this plate is as dialling handle.
Motor drive mechanism in the present embodiment comprises the linkage gear assembly 54 of motor 52, thumb wheel 53 and interlock output gear and the thumb wheel with output gear 51, described motor drives thumb wheel reciprocating rotation by linkage gear assembly, and and then by thumb wheel, drive and dial handle reciprocating rotation, dial handle due to relative being fixedly installed of manual trigger piece with external small-sized plastic-shell switch, thereby drive manual trigger piece to carry out divide-shut brake action.On described thumb wheel, be fixed with plate 55, the outboard end of this plate stretches out insulation crust as dialling handle.
In the present embodiment, described linkage gear assembly comprises the master gear 541 that is fixedly installed on bearing pin 544, be slidably arranged in pinion 542 on bearing pin, be arranged on coil 545 on master gear, be arranged on yoke 546 on pinion, for back-moving spring 547 that pinion is pushed away towards the direction away from master gear, be arranged on the ball 548 between master gear and pinion; The adjacent surface 5411 in abutting connection with pinion of master gear is provided with a plurality of spacing holes 549 that be arranged in parallel with bearing pin bearing of trend, ball is positioned at the openend of spacing hole, each back-moving spring is arranged in a corresponding spacing hole, its outboard end is connected on ball, and makes ball protrude from master gear for the adjacent surface in abutting connection with pinion; After coil electricity, adsorb yoke, thereby overcome the elastic force of back-moving spring, drive pinion to be connected on the adjacent surface of master gear, now master gear drives pinion to rotate by the effect of frictional force, and then drives thumb wheel to rotate.
