Abstract

The utility model discloses a pair of novel air scissors, which belongs to scissors used for tree care. The pair of novel air scissors comprises a handle main body; a cylinder is fixedly connected to the front end of the handle main body; a piston rod is arranged at the center of the cylinder; a spring, an air pipe passing through the inner chamber of the handle main body and an air valve in the middle of the air pipe are arranged at the rear end of the cylinder; the air valve is matched with the switch at the side end of the air valve; a fixing seat is arranged at the front end of the cylinder; the front end of the fixing seat is fixedly connected with a hollow tube; a pull rod connected and matched with the piston rod of the cylinder is arranged in the hollow tube; an upper cutter connecting device is fixed at the tail end of the pull rod; an upper cutter is fixed on the upper cutter connecting device; a lower cutter fixing seat is fixed at the end of the hollow tube; and a lower cutter is fixed on the lower cutter fixing seat. According to the utility model, a generally known mechanical cylinder principle is introduced into the structure of a pair of long-handled tree scissors, so that the purpose of pruning branches effectively by utilizing working strength and interstitial velocity of the cylinder is achieved. The pair of novel air scissors has a simple structure, light weight and high working efficiency, and is convenient and reliable to use.

Description

A kind of novel gas is cut

Technical field

The utility model relates to the scissors that uses in the trees maintenance, and a kind of specifically novel gas is cut.

Background technology

Trees, especially the maintenance of fruit tree is to prune, and could obtain the good harvest of good quality and high output.Yet because branch aloft, is to cut with general scissors, people have invented the stock scissors for this reason, of scissors is cut handle fix, and another is cut handle and utilizes the steel wire rope pulling, and the branch of eminence is pruned.Because people's pulling force is limited, the speed between the crack has received limitation especially, and therefore the branch cut off of many needs can't be cut, and have to climb the tree its saw (cutting) down or the like.Simultaneously, existing stock scissors operates not only inconvenient, and is great to people's physical demands.

The utility model content

In order to overcome the defective that existing stock is cut, the purpose of the utility model is that a kind of novel gas that will provide a kind of air pressure realization that utilizes cylinder rational in infrastructure, that volume is little, in light weight, easy to use and reliable to shear is cut.

The utility model solves the technical scheme that its technical problem adopted: a kind of novel gas is cut; It is characterized in that: a handle main body is arranged; The front end of handle main body is fixedly connected with a cylinder; The center of cylinder is provided with piston rod, and the rear end of cylinder is provided with spring and through the tracheae of handle main body inner chamber and the air valve in the middle of the tracheae, air valve matches with the switch of its side; The front end of cylinder is provided with holder; The front end of holder is fixedly connected with hollow pipe; Be provided with the pull bar that is connected cooperation with cylinder piston rod in the hollow pipe, be fixed with the upper slitter jockey on the end of pull bar, be fixed with upper slitter on the upper slitter jockey; The termination of hollow pipe is fixed with down the cutter holder, is fixed with down cutter on the following cutter holder.

Described air valve matches with switch, and wherein the part of switch is the outer end of stretching out the handle main body inner chamber.

Before the utility model work, upper slitter is in open mode with following cutter, in the time will carrying out branch pruning; At first the upper slitter of open mode and following cutter, bracket is pressed switch then wanting the clipped position of pollard; Air valve is promptly opened automatically, and the gas in the high pressure gas bucket will get into air valve by air inlet pipe, arrives cylinder then; Cylinder just makes piston sharply downward under the effect of high pressure gas, and piston rod is joining pull bar, pull bar sharply downwards; It is closed also to have spurred upper slitter jockey and upper slitter, thereby branch is cut off.When decontroling switch, air valve is got back to the origin-location, and the gas in the cylinder will be discharged from venthole, and the cylinder inner carrier will back into the origin-location to piston under spring action, thereby pull bar has also spurred the upper slitter jockey, makes upper slitter and following cutter be in opening.

The beneficial effect of the utility model is: owing to the utility model is incorporated into known cylinder principle in the machinery in the structure of stock hedge clipper, thereby the strength and the interstitial velocity that effectively utilize cylinder work reach the purpose of pollard effectively.The structure of the utility model is not only simple, and in light weight, and is easy to use and reliable, can alleviate operator's physical load, improves its operating efficiency effectively.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the preceding Status view of work of the utility model.

Fig. 2 is the view that opens the state of closing during the utility model is sheared.

1 handle main body among the figure, 2 cylinders, 3 piston rods, 4 springs, 5 tracheaes, 6 air valves, 7 switches, 8 holders, 9 hollow pipes, 10 pull bars, 11 upper slitters, 12 upper slitter jockeys, 13 times cuttves, 14 branch hooks, 15 handles of shaking hands, 16 times cutter holders.

Hook was placed on the usefulness of bearing when down the lower end of cutter 12 was provided with branch hook 14 and can be used as the hook branch and do not use gas to cut among the figure.

To stretch out the lower end of handle main body 1 be directly to be connected with the air compressor air supply pipe to tracheae 5 among the figure.

Embodiment

Embodiment 1:

See also view; A handle main body 1 is arranged; The front end of handle main body 1 is fixedly connected with a cylinder 2; The center of cylinder 2 is provided with piston rod 3, and the rear end of cylinder 1 is provided with spring 4 and through the tracheae 5 of handle main body 1 inner chamber and the air valve 6 in the middle of the tracheae, air valve 6 matches with the switch 7 of its side; The front end of cylinder 2 is provided with holder 8; The front end of holder 8 is fixedly connected with hollow pipe 9; Be provided with the pull bar 10 that is connected cooperation with cylinder piston rod 3 in the hollow pipe 9, be fixed with upper slitter jockey 12 on the end of pull bar 10, be fixed with upper slitter 11 on the upper slitter jockey 12; The termination of hollow pipe 9 is fixed with down cutter holder 16, is fixed with down cutter 13 on the following cutter holder 16.

14 is the branch hook among the figure, and 15 are the handle of shaking hands.
