Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of space to save greatly at existing background technology, makes the security control mechanism of the pruner that pruner reliability and safety improve greatly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of security control mechanism of pruner, it includes control pruner electromotor work whether microswitch, Top carry handle and assistant's handle are arranged respectively on the casing, it is characterized in that microswitch is fixed in the Top carry handle of casing, Top carry handle connects mobilizable Top carry handle button below by pivot pin simultaneously, be supported with main push-button reset spring between Top carry handle button inboard and the Top carry handle, Top carry handle button inboard also is connected with rotating driving lever simultaneously, and be equipped with limiting component, an end that makes driving lever cooperates contact with microswitch or separates, the driving lever other end is connected with cable wire, cable wire is connected last assistant to button one end with the assistant of casing by the space in the casing, and assistant is button to be fixed on the assistant of casing versatilely last by pivot pin.
It is fixed on above-mentioned cable wire by pull head in the holder of driving lever one end, and simultaneously cable wire is installed with the driving lever back-moving spring, and this spring is supported on position between the end of driving lever and Top carry handle button, and close holder place Top carry handle button forms spacing floor.
Its other end of above-mentioned cable wire passes the flexible axle holder that is fixed in the casing and is fixed on assistant in the holder of button one end by pull head, and cable wire is with sleeve pipe, and is provided with guide rib cooperates with cable wire in enclosure space.
Above-mentioned assistant is being connected with secondary push-button reset spring between button and the assistant's handle.
Compared with prior art, advantage of the present utility model is: because cable wire can freely be arranged in casing, so it is smaller that institute takes up space, and provide convenience for the shape-designing of pruner, avoided the steel wire easy deformation to follow the string and caused the malfunctioning defective of interlinked mechanism, improved the reliability and the safety of pruner, entire mechanism is succinct, manufacture easily, be adapted at promoting the use of on the pruner.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As schematically shown in Figure 1, a kind of security control mechanism of pruner, its casing is equipped with electric machine assembly 8 for 20 li, and casing 20 also has Top carry handle 1 and assistant respectively 11 simultaneously, general Top carry handle 1 design on the control crank of pruner, assistant 11 design and installations on handle.Control machine operation whether microswitch 4 is fixed on 1 li cavity of Top carry handle, and Top carry handle 1 a following side is connected with pivot pin, connects mobilizable Top carry handle button 2 by this pivot pin.Top carry handle button 2 inboards are centre position moulding reference column roughly, on overlap main push-button reset spring 3, Top carry handle 1 has spring base in correspondence position design, main push-button reset spring 3 just is supported on reference column and the spring base.2 li opposite sides of Top carry handle button are connected with rotating driving lever 5 by pivot pin 6, and an end of driving lever 5 and microswitch 4 cooperate contact or separate, and the other end forms holder 18, and the pull head positioning and fixing of cable wire by the one end is 18 li of the holders of driving lever.In order to have improved the reliability of release mechanism, this end of cable wire is installed with driving lever back-moving spring 7, make this spring be supported on position between the end of driving lever 5 and Top carry handle button 2, and forming spacing floor 17 near holder place Top carry handle button 2, can further guarantee under the state that Top carry handle button 2 is not pressed like this, no matter whether auxiliary-handle button 9 is pressed, and driving lever 5 ends all can not touch microswitch 4, have avoided casualty accident.Cable wire 16 is with sleeve pipe 15, under guide rib 19 guide effects that are provided with in the enclosure space, passes the spatial joint clearance in the casing, with the assistant of casing the assistant on 11 is connected button 9 one ends.Install for convenience, cable wire 16 other ends pass flexible axle holder 14 backs that are fixed in the casing and are fixed on assistant in the holder of button end by pull head 12.The assistant that assistant also is fixed on casing to position, button 9 the inside by pivot pin 10 versatilely is on 11, and near this side, assistant is connected with secondary push-button reset spring 13 to button 9 and assistant between 11, make assistant normally be in not down state to button.
Its operation principle is as follows: when Top carry handle button 2 and assistant did not press button 9, this moment, the end of driving lever 5 was away from microswitch 4 under 7 effects of driving lever back-moving spring, so microswitch 4 can not be touched, pruner can not worked, and its structure is referring to Fig. 1; When Top carry handle button 2 is pressed and assistant when button 9 is not pressed, though overcome the elastic force of main push-button reset spring rotates owing to Top carry handle button 2, make driving lever 5 ends further near microswitch 4, but because assistant is not pressed button 9 as yet, make driving lever 5 under the effect of driving lever back-moving spring 7 away from microswitch 4, the end of driving lever 5 still can not touch microswitch 4, microswitch 4 can not be touched like this, pruner still can not worked, and its structure is referring to Fig. 2; When Top carry handle button 2 is not pressed and assistant when button 9 is pressed, the end of driving lever 5 is under the pulling of cable wire 16, can overcome the elastic force of driving lever back-moving spring 7 and rotate, but, can not rotate too much, under the situation that Top carry handle button 2 is not pressed owing to be subjected to the restriction of spacing floor 17, the end of driving lever 5 is still with a certain distance from microswitch 4, microswitch 4 can not be touched, and pruner can not worked, and its structure is referring to Fig. 3; When Top carry handle button 2 and assistant press button 9, Top carry handle button 2 has overcome the elastic force of main button spring 3 and has rotated, the end that makes driving lever 5 is near microswitch 4, simultaneously because the pulling function of cable wire 16, make driving lever 5 also overcome the elastic force of driving lever back-moving spring 7 and rotate, make the end of driving lever 5 can touch microswitch 4, at this moment, pruner just can be worked, and has ensured safety in utilization, and its structure is referring to Fig. 4.
