Further restriction to technique scheme, described gear restriction elastic element is that cross section is the Spring sheet clip of U-shaped, on the internal surface of Spring sheet clip two jig arm, be arranged with the curved surface coordinating with gear draw-in groove, the tube wall of guide pipe is provided with mounting groove, and Spring sheet clip is arranged on guide pipe by mounting groove.
Further restriction to technique scheme, described gear restriction elastic element is dead bolt, and dead bolt is cylindrical, and one end that dead bolt contacts with gear draw-in groove is provided with the concave curved surface coordinating with gear draw-in groove, guide pipe is provided with fixed base, and dead bolt is arranged on guide pipe by fixed base.
Further restriction to technique scheme, described gear restriction elastic element is elastic sphere, and the tube wall of guide pipe is provided with mounting groove, and the ball of elastic sphere is arranged in mounting groove, and the outside of ball is provided with the fixedly elasticity retainer of ball.
Further improvement to technique scheme, described push-pull cable gear selection device is arranged in seal element, the dust-proof cover that seal element is corrugated tube shape.
Beneficial effect:
1. in the present invention, the gear draw-in groove on pull bar and the restriction of the gear on guide pipe elastic element snap-fit are selected and lock function to realize gear, needs to gear appropriateness latch functions in the time of can solving well power-driven tool and need to select gear shift, valve to control, avoid gear select to lose efficacy, out of supply; Can stop well simultaneously, reduce because shake that controlled unit is in operation as gearbox etc., vibrations are to the transmission of gear selection device, reduce in gear selection device as the shake of gear shifting handle, vibration, raising operator controls travelling comfort;
2. can to select be as required that Spring sheet clip, dead bolt or elastic sphere simple in structure realized gear and selected and locking to the gear in the present invention restriction elastic element, obtains the function of more excellent system and good cost performance;
3. highly versatile of the present invention, as long as control system adopts in the situation of push-pull cable as transmission of power carrier, the gear that just can use the present invention to realize needs is selected and locking, does not need gear selection device, controlled unit in original control system to make any change;
4. strong adaptability of the present invention, is changed by the numbers of gear steps of control object, lock position, can on pull bar, process easily corresponding gear draw-in groove and realize, and does not need again to develop operator, controlled unit etc.; The size of locking power can be easily can easily realize by the section configuration of adjusting the pretightening force of gear restriction elastic element and/or changing draw-in groove on pull bar;
5. the present invention compares increases gear selection and latch functions on existing apparatus, structure of the present invention the most simply, more reliable, economic and practical, realize cost lower.
