Abstract

The utility model discloses a pair of fast garden scissors which comprise a supporting frame, an air cylinder, a first scissors body, a second scissors body, a change-over valve and an air supply box, wherein the air cylinder is arranged in the supporting frame, and an air outlet hole of the air supply box is connected with an air pump. The lower end of the first scissors body is fixed on the supporting frame, and the lower end of the second scissors body is hinged to a piston rod of the air cylinder; the middle of the first scissors body is rotationally connected with the middle of the second scissors body through a rotating shaft assembly which comprises a rotating barrel; the front end and the rear end of the air cylinder are both provided with air guide ports, and the two air guide ports are connected with two air outlets of the change-over valve through air pipes; an air inlet of the change-over valve is connected with the air supply box through an air inlet pipe. According to the fast garden scissors, the piston rod moves forwards or backwards to drive the second scissors body to move, and therefore clipping motions are achieved. Therefore, the first scissors body and the second scissors body do not need to operated by workers, and the fast garden scissors are beneficial to reducing labor intensity of the workers.

Description

Gardens scissors with high speed

Technical field

The utility model relates to a kind of gardens scissors with high speed.

Background technology

In daily life, often need to utilize garden shear that trees, flowers and plants are pruned, to play the effect of beautifying the environment.Existing garden shear comprises that first cuts body, second and cut body; This first cuts body and the second middle part of cutting body is equipped with rotating shaft to realize that first cuts body and the second rotation of cutting body, and the front end of described rotating shaft is fixed with limited cap, its rear end limited location nail that is threaded; Described first cuts and is provided with the first shear blade on the body, and second cuts and be provided with the second shear blade on the body.And this garden shear need to be cut body and second by manual operation first and cuts body and move to realize that it prunes action, causes workman's labour intensity larger.

The utility model content

For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of gardens scissors with high speed that is conducive to reduce labour intensity.

For achieving the above object, the utility model adopts following technical scheme:

Gardens scissors with high speed comprises bracing frame, is installed in cylinder in the bracing frame, is provided with first of the first shear blade and cuts body, be provided with second of the second shear blade and cut the feeding tank that is connected with air pump on body, reversal valve, its venthole; Described the first lower end of cutting body is fixed on the bracing frame, and the second lower end of cutting body is hinged on the piston rod of cylinder; Described first cuts body, second cuts the middle part of body and is rotatably connected by the turning cylinder assembly, and described turning cylinder assembly comprises interting to be cut body and second first and cut rotating cylinder in the body perforation, and the front end of this rotating cylinder is provided with limited cap, and its rear end is installed with jump ring; The rear and front end of described cylinder is equipped with air guide port, and described two air guide ports are connected with two gas outlets of reversal valve respectively by tracheae; The air inlet of described reversal valve links to each other with feeding tank by air inlet pipe.

This gardens scissors with high speed comprises that also the change-over key for the control reversal valve constantly alternately carries out forward rotation and counter-rotational control device.

Described first cuts body and second cuts the edge Circle-Array of the perforation of body and shows three oil guide groove.

The gardens scissors with high speed that the utility model is set forth, its beneficial effect is:

Change-over key by the control reversal valve is done forward rotation or backward rotation, gas is entered in the cylinder from different air guide ports, thereby the piston rod that promotes cylinder moves forwards or backwards, cut the body motion to drive second, can realize that its pruning action is to cut off the branch between the first shear blade and the second shear blade, therefore, need not manual operation first and cut body and second and cut body, be conducive to reduce workman's labour intensity; And, constantly alternately carry out forward rotation and backward rotation by the change-over key that utilizes control device control reversal valve, piston rod is constantly moved reciprocatingly, cut body and constantly do forward and reverse rotatablely moving to drive second, can finish rapidly pruning work, improve its operating efficiency.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Wherein, 1, bracing frame; 2, cylinder; 21, air guide port; 23, piston rod; 3, first cut body; 31, the first shear blade; 4, second cut body; 41, the second shear blade; 5, reversal valve; 51, change-over key; 6, rotating cylinder.

Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further, so that clearerly understand the utility model technical thought required for protection.

As shown in Figure 1, be a kind of gardens scissors with high speed of the utility model, comprise bracing frame 1, be installed in cylinder 2 in the bracing frame 1, be provided with first of the first shear blade 31 and cut body 3, be provided with second of the second shear blade 41 and cut the feeding tank that is connected with air pump on body 4, reversal valve 5, its venthole; Described the first lower end of cutting body 3 is fixed on the bracing frame 1, and the second lower end of cutting body 4 is hinged on the piston rod 23 of cylinder 2; Described first cuts body 3, second cuts the middle part of body 4 and is rotatably connected by the turning cylinder assembly, and described turning cylinder assembly comprises interting to be cut body 3 and second first and cut rotating cylinder 6 in body 4 perforation, and the front end of this rotating cylinder 6 is provided with limited cap, and its rear end is installed with jump ring; The rear and front end of described cylinder 2 is equipped with air guide port 21, and described two air guide ports 21 are connected with two gas outlets of reversal valve 5 respectively by tracheae; The air inlet of described reversal valve 5 links to each other with feeding tank by air inlet pipe.

Preferably, this gardens scissors with high speed comprises that also the change-over key 51 for control reversal valve 5 constantly alternately carries out forward rotation and counter-rotational control device.Described first cuts body 3 and second cuts the edge Circle-Array of the perforation of body 4 and shows three oil guide groove.

Change-over key 51 by control reversal valve 5 is done forward rotation or backward rotation, gas is entered in the cylinder 2 from different air guide port 21, thereby the piston rod 23 that promotes cylinder 2 moves forwards or backwards, cut body 4 motions to drive second, can realize that its pruning action is to cut off the branch between the first shear blade 31 and the second shear blade 41, therefore, need not manual operation first and cut body 3 and second and cut body 4, be conducive to reduce workman's labour intensity; And, constantly alternately carry out forward rotation and backward rotation by the change-over key 51 that utilizes control device control reversal valve 5, piston rod 23 is constantly moved reciprocatingly, cut body 4 and constantly do forward and reverse rotatablely moving to drive second, can finish rapidly pruning work, improve its operating efficiency; And the turning cylinder assembly can be convenient to carry out rapidly first to cut dismounting and the installation that body 3 and second is cut body 4 by adopting the design of rotating cylinder 6 and jump ring, is conducive to promote; And by adopting the design of oil guide groove, can be convenient to lubricating oil is guided on perforation and the rotating cylinder 6 rapidly, can cut body 4 to second to be lubricated and to make its rotation more flexible, and can reduce the probability that part gets rusty.
