(III) advantageous effects

Compared with the prior art, the invention provides the garden greening scissors capable of adjusting the shearing force, and the garden greening scissors have the following beneficial effects:

1. this can adjust afforestation scissors of shearing strength uses through the cooperation of flexible gasbag and transition gear, when pruning trees branch, the handheld handle of workman removes the scissors to the position that the branch is in between back of a knife blade and the tool bit.

Through the extrusion handle, carry out the extrusion shearing to the branch, at this in-process, air spring is stretched, in case the branch can't be cut off, the handle can last the extrusion, lead to air spring to last stretched, and then lead to its inner space increase, bleed to flexible gasbag through the hose, lead to the inside gas loss of flexible gasbag and shrink, make the profile bar move to flexible gasbag center department, extrude the pressure switch, lead to the motor anticlockwise rotation of control transition gear.

Transition gear anticlockwise rotation will drive with its engaged extrusion ratch, then the pulling handle removes to the transition gear direction, so the branch can be continued the extrusion shearing, finally cut off, so as long as the too big unable workman of branch intensity cuts off through, transition gear just can rotate, the pulling extrusion ratch is handle body shearing force, make the branch can once be cut off, thereby reached when pruning the tree branch, guarantee once to be interrupted the branch, avoid damaging the effect of branch epidermis.

2. This can adjust afforestation scissors of shearing dynamics, cooperation through accepting wheel and ejector pin is used, when transition gear is started by the motor, the shearing force of scissors increases suddenly, it slides between tool bit and the back of a knife to lead to the branch very probably, the event is provided with the ejector pin, when transition gear is started by the motor, flexible gasbag shrink passes through pull rod pulling accepting wheel, and the arc arch of accepting wheel inner wheel surface just contacts with the ejector pin top, continuously rotate along with accepting the wheel, the ejector pin is extrudeed downwardly movement, the deflection pole that leads to the below takes place to deflect, will accept board extrusion upwards and move, with the ascending ejecting back of a knife of kelly, the kelly can block the branch between back of a knife and the tool bit, prevent that the branch from sliding along the back of a knife when continuing the extrusion shearing, thereby reached and prevented the gliding effect of branch when shearing the branch through motor power.
