Abstract
The utility model provides a striker type switching device of a pair of electric pruning scissors. The striker type switching device comprises a fixed blade, an L-shaped striker is arranged on the outer side of the fixed blade and composed of a vertical striker edge, a transverse striker edge and a striker inflection point, the striker inflection point is rotationally connected with the fixed blade through a connection device and is located on the region, below the cutting edge, of the fixed blade, a light spring is arranged in the direction perpendicular to the transverse striker edge, the free end of the transverse striker edge is located above a motor switch, and when the fixed blade and a movable blade of the electric pruning scissors are in an open state, the free end of the vertical striker edge is higher than the upper end of the fixed blade. The striker type switching device has the advantages that a gardener no longer needs to pull the switch below an enclosure of the electric pruning scissors by hand when pruning branches, the structure is simple, operation is conducted conveniently and easily, and it can be avoided that finger joints are in pain because the switch is pulled by fingers of the gardener high frequently for a long time.
Description
Technical field
The utility model belongs to graden machine field, especially relates to a kind of firing pin type switching device of electric pruner.
Background technology
At present, in the pruning process of gardening gardens and fruits and vegetables, traditional pruning need to manually hold with scissors the handle of holding pruner, to realize the operation of pollard or rhizome, but general operation personnel's pruning workload is larger, and traditional pruner cannot satisfy the demands.
Chinese invention patent, application number 201110206372.6, a kind of electric pruner is disclosed, electric pruner comprises casing, in this casing, accommodate motor, transmission mechanism, built-in battery, switch trigger and safety switch are equipped with in the below of casing, in order to control the opening and closing of motor, the rear portion of casing forms grip portions, movable blades and fixed blade extend from the front end of casing, gear drives rotation by motor, and movable blades is done reciprocally swinging by gear driven, thereby implements shearing work.This patented technology is easy to use, reasonable in design, and market prospects are wide.
The appearance of above-mentioned electric pruner, has shortened the pruning time, has improved pruning efficiency, is deeply subject to liking of prune picker.But point operating switch trigger because of needs, use for a long time this type of electric pruner, finger-joint can be ached, even can inflammation.Therefore, be badly in need of the switch of this type of electric pruner to improve.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of electric pruner, and firing pin type switching device is housed on its fixed blade, is especially applicable to prune picker's high strength, prunes operation for a long time.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of firing pin type switching device of electric pruner, comprise fixed blade, described fixed blade outside is provided with L-type striker, described L-type striker is by striker vertical edge, striker horizontal edge and striker flex point form, described striker flex point is rotatably connected with described fixed blade by jockey, described striker flex point is positioned at the region of described fixed blade below blade, the vertical direction of described striker horizontal edge is provided with a light spring, described striker horizontal edge free end is positioned at the top of motor switch, at the described fixed blade of electric pruner and movable blades during in open configuration, the free end of described striker vertical edge is higher than the upper end of described fixed blade.
Preferably, described L-type striker is made by prestressing steel.
Preferably, described striker flex point be positioned at described fixed blade at blade the centre position with lower area, at the described fixed blade of electric pruner and movable blades, during in open configuration, the free end of described striker vertical edge is concordant with the upper end of described fixed blade.
Preferably, between described jockey and described fixed blade for removably connecting.
Advantage and the good effect that the utlity model has are: when the branch of needs pruning is encountered firing pin type switch, be equivalent to start motor, and enforcement shearing work, prune picker in the process of pollard without removing to pull the switch below electric pruner casing with hand again, firing pin type switch is highly sensitive, simple in structure, easy to operate understandable, make operator's finger can not produce articulations digitorum manus pain because of long-time high-frequency operating switch.

Embodiment
As shown in Figure 1-Figure 3, the firing pin type switching device of a kind of electric pruner of the present utility model, comprise fixed blade 1, described fixed blade 1 outside is provided with L-type striker 2, described L-type striker 2 is by striker vertical edge 21, striker horizontal edge 22 and striker flex point 23 form, described striker flex point 23 is rotatably connected with described fixed blade 1 by jockey 3, described striker flex point 23 be positioned at described fixed blade 1 at blade the centre position with lower area, the vertical direction of described striker horizontal edge 22 is provided with a light spring 4, described striker horizontal edge 22 free ends are positioned at the top of motor switch 5, at the described fixed blade 1 of electric pruner and movable blades during in open configuration, the free end of described striker vertical edge 21 is concordant with the upper end of described fixed blade 1, described L-type striker 2 is made by prestressing steel, 1 of described jockey 3 and described fixed blade are for removably connecting.
The course of work of this example: in the process of pollard, the described fixed blade 1 of electric pruner and movable blades are in open configuration, treat that poll enters between the blade of described fixed blade 1 and movable blades, and touch described striker vertical edge 21, described L-type striker 2 rotates under the thrust of poll treating, the described light spring 4 of described striker horizontal edge 22 compression, the free end of described striker horizontal edge 22 is touched described motor switch 5, motor entry into service, and make movable blades to down cut branch by gearing, tree shears is had no progeny, described striker horizontal edge 22 sets back under the bounce effect of described spring 4, the free end of described striker horizontal edge 22 is separated with described motor switch 5, motor shuts down, movable blades no longer carries out shearing manipulation.Above operating process is simple and convenient, and described L-type striker 2 sensitivitys are high, without remove to pull again the switch of electric pruner casing below with hand, makes operator's finger can not produce articulations digitorum manus pain because of long-time high-frequency operating switch.
Operator, be finished after electric pruner, for electric pruner is deposited conveniently, described L-type striker 2 can be disassembled, another for depositing, and the convenient maintenance test to described L-type striker 2, if flexural deformation has appearred in described L-type striker 2, can change in time to it.
In addition, described L-type striker 2 is made by prestressing steel, is difficult for flexural deformation, long service life.
