Embodiment

The technical scheme in the utility model embodiment will be clearly and completely described below, it is clear that described Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to The scope of the utility model protection.

Referring to Fig. 1, a kind of garden instrument, including handle 1 and the speed-regulating switch 2 in handle 1 for speed governing, handle There are the switch trigger 3 and anti-self-locking trigger 4 of flexible connection on 1, anti-self-locking trigger 4 is pulled with the switch clamping of trigger 3 with limit switch Machine 3 is rotated, and anti-self-locking trigger 4 rotates disengaging switch trigger 3 and releases the limitation to switch trigger 3, and switch trigger 3, which rotates to touch, to be adjusted Speed switch 2 carries out speed governing.

In addition, switch trigger 3 and anti-self-locking trigger 4 are hinged on handle 1 and rotated around handle 1.

In addition, the angle that switch trigger 3 is rotated is α, α controls the rotating speed of reduction to be directly proportional to speed-regulating switch 2.High or low Under shelves state, by adjusting finger gripping holding force F3 size, figure can be shown in the angle [alpha] size of controlling switch trigger 3.So that Obtain the stroke of speed-regulating switch 2 and produce change, cause resistance to produce change, the change changes into electric signal transmission to PCB, on PCB Control unit changed according to it by signal, export corresponding tach signal.Need temporarily to use the slow-speed of revolution, can be appropriate Loosen switch trigger 3, increase α angles, reduce rotating speed；Need to use high rotating speed, can appropriate clamping switch trigger 3, reduce α Angle, improves rotating speed.

In addition, the front end of switch trigger 3 has limit rib 5, the front end of anti-self-locking trigger 4 has snap fit 6, snap fit 6 and limit The position clamping of muscle 5 is rotated with limit switch trigger 3, and snap fit 6 departs from limit rib 5 and unlocks the limitation to switch trigger 3.Switch trigger 3 Rotation makes limit rib 5 touch the progress speed governing of speed-regulating switch 2.

In addition, being equipped with switch trigger 3 on the reduction torsion spring 7 of switch trigger 3 for resetting switch trigger 3, anti-self-locking trigger 4 Equipped with the anti-self-locking trigger torsion spring 8 for resetting anti-self-locking trigger 4.

Gear push pedal is slidably connected in addition, being additionally provided with handle 1 on the microswitch 9 of control gear switch, handle 1 10, gear push pedal 10 translates to touch microswitch 9 on handle 1.The lower end of gear push pedal 10 has trigger arm 11, trigger arm 11 Microswitch 9 is contacted to trigger microswitch 9.

In addition, there is salient point 13 in gear muscle 12 on handle 1, gear push pedal 10, the limitation gear of gear muscle 12 push pedal 10 Salient point 13.The salient point 13 of gear push pedal 10 is blocked on the right side of gear muscle 12 of handle 1, is made its trigger arm 11 away from microswitch 9, is made It must switch in free state.When enforcing 10 push pedal of gear, the gear muscle 12 on handle 1 is produced by the pressure of salient point 13 Changed shape, concedes space so that gear push pedal 10 can be promoted forward, when salient point 13 runs to gear 12 left side of muscle, gear Muscle 12 springs back to home position and blocks salient point 13, and at this moment gear push pedal 10 can not move right, and its trigger arm 11 will be pushed down micro- Dynamic switch 9, is at closure state；The switch of closure produces an electric potential signal, is transferred on PCB control panels, cuts it Change high-grade state into.Run into need long-time low speed run when, can directly by push pedal switch shift low or first gear onto.

In addition, being provided with the body of rod 14 in the middle of handle 1, speed-regulating switch 2 is located at the body of rod 14 1 located at the top of the body of rod 1, switch trigger 3 Side, microswitch 9 is located at the opposite side of the body of rod 14.

The utility model garden instrument concrete operating principle is as follows：When switching free state, anti-self-locking trigger 4 is by anti- The torsion F1 of self-locking trigger torsion spring 8 is pressed on switch trigger 3 so that switch can not be triggered.During start machine, human hand grips hand During handle 1, anti-self-locking trigger 4 is pressed, anti-self-locking trigger 4 is pressed downward by production pressure F2, makes anti-self-locking trigger 4 along dextrorotation Turn, snap fit 6 departs from the limit rib 5 of switch trigger 3, then pressing switch trigger 3, switch trigger 3 is stressed F3, makes it along the inverse time Pin rotates, so that limit rib 5 triggers speed-regulating switch 2.After machine has been used, trip switch trigger 3, in the work of debugging switch Firmly under F4, initial position is returned to clockwise, because the directed force F 4 of speed-regulating switch 2 can be gradually reduced with the reset of switch, is Ensure that switch trigger 3 can completely return to home position, a switch trigger torsion spring 7 is added on this structure, so The power F5 of formation can just cover the shortage, it is ensured that the switch return of trigger 3 is normal.After 3 return of trigger is switched, anti-self-locking trigger exists 1 time rotate counterclockwise of directed force F of torsion spring, returns to initial position, and clamping switch trigger 3, makes entirely to develop triggering system time To initial position.

Be different from prior art, the utility model garden instrument, can user's speed governing gearshift use demand at a slow speed, structure closes Reason, it is easy to use.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases The technical field of pass, is similarly included in scope of patent protection of the present utility model.
