Description

Scissors for pruning green belt

Technical field

The pruning scissors that a kind of greenbelt is used belongs to the garden instrument field.

Background technology

Now the employed greenbelt of people is repaired scissors, carrying out shorter greenbelt when cutting flat, stoop labor, the comparison fatigue that works together has influenced operating efficiency, and long-term work also causes lumber ertebral disc outstanding easily, therefore, people's pruning tool of waiting in expectation and being more suitable for using.

Summary of the invention

Purpose of the present invention is the greenbelt equating scissors that a kind of operation of can standing will be provided.The structure of scissors is made up of scissors bit, cutter shaft, gear, hilt, handle and rope sling.The handle of conventional scissors is removed from the back of scissors shaft, make scissors keep one section behind cutter shaft, Here it is cutter head connects the worm gear seat of gear, and makes the worm gear longitudinal axis parallel with cutter shaft on this cross section; The composition of gear is made up of worm gear seat, the worm gear longitudinal axis, U-shaped worm gear and worm gear transverse axis.The worm gear longitudinal axis is installed on the worm gear seat, and two of the worm gear longitudinal axis is fixed in the axis hole of worm gear seat, is provided with knob above two of the worm gear longitudinal axis, rotates the worm gear longitudinal axis with this; Intermediate shaft hole at the U-shaped worm gear is installed the worm gear transverse axis, and two of worm gear transverse axis is fixed in the transverse axis axis hole of worm gear seat.Bottom semicircular place at the U-shaped worm gear is provided with the gear teeth, and the groove of the gear teeth and the worm gear longitudinal axis is meshed; The knob of the rotation worm gear longitudinal axis can make the U-shaped worm gear do rotation within 180 degree, thereby adjusts the angle of cutter head and hilt and hilt and handle.The end socket of the upper end of U-shaped worm gear and the bassoon of hilt one end is fixedly linked, hilt is the telescopic handle of living, adopt the double-layer tube structure, a tubule promptly is installed in bassoon, large and small pipe is isometric, and tubule is can be in bassoon movable back and forth but do not rock, and end socket is connected to an end of large and small pipe and handle, y direction at large and small pipe upper edge pipe is provided with an exhausting hole, and through-hole diameter on the large and small pipe and distance between borehole are equal fully respectively.Insert pivot pin in the through hole of large and small pipe, large and small pipe is connected and fixed becomes one.By to the drawing, contract and the transposition of through hole of large and small pipe, can change the Len req of hilt; Between handle and hilt, adopt same gear to connect, method is that the end socket and the worm gear seat of tubule one end of hilt is fixedly linked, an end end socket of U-shaped worm gear and handle is fixedly linked, and makes the worm gear longitudinal axis parallel with cutter shaft; Handle is one section tubular structure, and the outside is with sleeve, and sleeve is made with plastic material.Laterally be provided with circular hole on the cutter shaft at one end, connect the rectangle shackle on the circular hole, the middle upper portion of shackle is provided with dog hole, and shackle can be around the circular hole swing; On shackle, connect rope sling, rope sling is made with belt, the upper end of rope sling is a ring-type, in the middle of the lower end of rope sling, connect hook, one section is provided with several dog holes above the hook of rope sling, the hook of rope sling can directly hang on the dog hole, also hook can be passed shackle and hang over then on the dog hole, adjusts the length of required rope sling with this.

During work, people's operation of standing is enclosed within rope sling on the neck, bears the part weight of scissors with this; According to the greenbelt desired height, mix up the length of rope sling, adjust the length of hilt again according to the operation needs, and the relative angle of cutter head, hilt and handle, just can enter the station and cut flat operation.The time spent does not take down pin, pulls up tubule, just can dwindle the scissors geometric volume.
