Abstract
The utility model relates to pneumatic gardening prunning shears, comprising an immovable blade and a movable blade hinged in the middle, which is characterized in that a handle of the immovable blade is fixed on a cylinder; a handle of the movable blade is driven by a pneumatic piston. The pneumatic gardening prunning shears have the advantages of simple structure and convenient use, which can reduce the labor intensity and improve the working efficiency.
Description
Technical field
The utility model relates to a kind of pneumatic gardening secateurs.
Background technology
When large-area fruit tree or flowers and plants will be pruned, owing to use traditional fruit tree scissors to prune comparatively effort, labour intensity was big, and prunes inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of pneumatic gardening secateurs, and this product configurations is simple, and is easy to use, can reduce labour intensity, increases work efficiency.
Pneumatic gardening secateurs of the present utility model, comprise that scissors is made of ledger-plate and the knife section that the middle part is hinged, it is characterized in that: the ledger-plate shank is fixed on the cylinder block, be provided with air rammer and piston rod thereof in the described cylinder block, described piston rod external part and knife section shank are hinged and are used to drive scissors work, the other end is connected with the piston that is provided with O-ring seal, so that the piston rod external part makes piston and the relative cylinder axis axis of O-ring seal produce when doing movement in a curve with the pommel of knife section swings (and O-ring seal is the lip structure, under the compressed air effect of work air chamber, open, thereby be adjacent to cylinder inner wall and produce sealing function), be provided with the back-moving spring that is enclosed within the piston rod periphery between the port of close piston rod external part one side of cylinder and the piston, reset with driven plunger, the cylinder block of described piston the other end is the work air chamber, and this work air chamber is provided with the high pressure inlet port by intake valve control.
Be hinged with air valve handle front end near described cylinder body and the ledger-plate hinged place, also be provided with on the described air valve handle and open the valve buckle, the cylinder body bottom side is withstood in the described valve buckle upper end of opening, the slotted eye of its bottom on the air valve handle stretches out downwards, middle and upper part and air valve handle are hinged, and be provided with to order about and open the torsionspring that the valve buckle resets, described air valve handle and the pin joint that opens the valve buckle to the distance of slotted eye rear end greater than opening valve buckle pin joint to the distance that opens valve buckle lower extreme point, so that allow when opening the reverse of valve buckle extremely with air valve handle parallel position, can be contained in fully in the slotted eye, to remove constraint the air valve handle.
Advantage of the present utility model is:
1. the high efficiency of long-time pruning fruit trees or flowers and plants, and laborsaving.
2. easy and simple to handle, gently detain the branch that the air valve handle just can be cut fruit tree or flowers and plants.
3. smooth, beautiful by the otch of pollard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1 intake valve.
Fig. 3 is the partial enlarged drawing of Fig. 1 air valve handle.
Among Fig. 1: β is the side-play amount of the relative cylinder axis axis of knife section shank.
Embodiment
The pneumatic gardening secateurs of the utility model embodiment, comprise that ledger-plate (1) and knife section (2) that scissors is hinged by the middle part constitute, it is characterized in that: ledger-plate (1) shank is fixed on the cylinder block, be provided with air rammer (3) and piston rod (4) thereof in the described cylinder block, described piston rod (4) external part and knife section (2) shank are hinged and are used to drive scissors work, the other end is connected with the piston that is provided with O-ring seal (5), so that piston rod (4) external part makes piston and the relative cylinder axis axis of O-ring seal produce when doing movement in a curve with the pommel of knife section swings (and O-ring seal is the lip structure, under the compressed air effect of work air chamber, open, thereby be adjacent to cylinder inner wall and produce sealing function), be provided with the back-moving spring (6) that is enclosed within the piston rod periphery between the port of close piston rod external part one side of cylinder and the piston, reset with driven plunger, the cylinder block of described piston the other end is work air chamber (7), and this work air chamber is provided with the high pressure inlet port by intake valve control.
In order to prevent under offhand situation, to pull air valve handle (8), cause danger, be hinged with air valve handle (8) front end near described cylinder body and the ledger-plate hinged place, also be provided with on the described air valve handle and open valve buckle (9), the cylinder body bottom side is withstood in described valve buckle (9) upper end of opening, the slotted eye of its bottom on air valve handle (8) stretches out downwards, middle and upper part and air valve handle are hinged, and be provided with to order about and open the torsionspring (10) that valve buckle (9) resets, described air valve handle (8) and the pin joint that opens valve buckle (9) to the distance of slotted eye (11) rear end greater than opening valve buckle (9) pin joint to the distance that opens valve buckle (9) lower extreme point, so that allow when opening valve buckle (9) reverse extremely with air valve handle (8) parallel position, can be contained in fully in the slotted eye, to remove constraint the air valve handle.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (2)
1. pneumatic gardening secateurs, comprise that scissors is made of ledger-plate and the knife section that the middle part is hinged, it is characterized in that: the ledger-plate shank is fixed on the cylinder block, be provided with air rammer and piston rod thereof in the described cylinder block, described piston rod external part and knife section shank are hinged and are used to drive scissors work, the other end is connected with the piston that is provided with O-ring seal, so that the piston rod external part makes piston and the relative cylinder axis axis of O-ring seal produce swing when doing movement in a curve with the pommel of knife section, be provided with the back-moving spring that is enclosed within the piston rod periphery between the port of close piston rod external part one side of cylinder and the piston, reset with driven plunger, the cylinder block of described piston the other end is the work air chamber, and this work air chamber is provided with the high pressure inlet port by intake valve control.
