Abstract

The utility model relates to high-level shears which can change the direction of cutting in multiple angle. The utility model mainly comprises a pair of shears composed of knife blades (11, 12), a long rod (15), a turning arm (16), a pulley block (13), a pull rope (18) and a spring (17). The utility model is characterized in that the turning arm and the long rod rotate and swing to change the angles of connection, using a connecting bolt (20) as a shaft, which changes the angle between the cutting plane of the shears and the long rod. Thus, people on the ground can trim branches which grow along different directions in the sky.

Description

The high altitude scissors of changeable angle

The utility model relates to a kind of people can carry out the high-altitude beta pruning on ground scissors, especially can multi-angle changes the high altitude scissors secateurs cutter of shear direction.

A kind of high altitude scissors of gardens personnel use at present, its structure colluding a body 1 top by axle 3 and spring 4 binding blades 2, collude a body 1 lower end and connect a stock 5 as shown in Figure 1, and stay cord 8 is around to be arranged on and colludes the pulley on pulley on the body 7 and the blade 6.One holds stock 5 during use, catches on branch with the hook-shaped position of colluding a body, and another pulls moving stay cord 8 makes blade 2 swings shear branch.Though having solved to climb up a tree, this kind high altitude scissors can prune eminence branch problem, but because the shear surface and the stock of the scissors of this structure are fixing parastate, therefore the scissors limb in vertical direction that can only prune and lift has been reduced the service efficiency of this scissors.

The purpose of this utility model is that a kind of high altitude scissors that is suitable for pruning the limb of various angles growths will be provided.

The utility model is made by following structure:

An one of scissors blade shank and the stock mat turnover arm that will have the universal architecture form that two blades form are connected, and change the shear surface of scissors and the angle between stock by the binding angle that changes between turnover arm and the stock; Hanging a spring on another blade of scissors and linking on the turnover arm, on the two blade pommels of scissors and the arm of transferring, assembly pulley is installed, stay cord is wound on earlier on the pulley of two blade pommels, descends around the pulley to the arm of transferring again, and the stay cord end is around being embedded on the handle.One hand-held stock, spurring stay cord can carry out cut operator on the other hand.And, can realize shearing the limb of various different directions growths by changing the binding angle of turnover arm and stock.

The utility model can carry out the high-altitude shearing manipulation of multi-angle because of having the turnover arm configuration that can change angle, and it is extremely convenient to use, and has improved the serviceability of habitual high altitude scissors effectively, and no longer is subjected to the restriction of the tree limb direction of growth; And because the handle setting is arranged, make to pull moving stay cord to carry out shear action safer reliable.

Describe in further detail below in conjunction with the structure of accompanying drawing the utility model.

Fig. 1 is the structural representation of a kind of high altitude scissors of the utility model correlation technique.

Fig. 2 is the structural representation of the utility model.

Fig. 3 is that Fig. 2 medium pulling rope [18] is around the schematic diagram that is embedded on the handle.

Fig. 4, Fig. 5, Fig. 6 are the user mode schematic diagram of the utility model when shearing the branch of various different angles.

With reference to Fig. 2 to Fig. 4, by blade [11], [12] scissors of composition universal architecture, blade (11) shank is connected with one of turnover arm (16) end, and make turnover arm [16] and scissor cut face be fixedly installed in blade [11] shank in vertical state, the other end of turnover arm [16] is connected by bolt [20] with stock [15], turnover arm [16] serves as convertible its connection angle of axle swing with stock [15] with connecting bolt [20], and by bolt [20], [21] clamping stock [15], hanging spring [17] on the blade [12] links with turnover arm [16], in blade [11], [12] pommel is installed assembly pulley [13], go up installation pulley [14] at turnover arm [16], stay cord [18] is wound on earlier on the assembly pulley [13], around descending to pulley [14], stay cord [18] is terminal around being embedded on the handle [19] again.

When not working, because the effect of spring [17] makes blade [11], [12] open-shaped attitude; When work, pulling stay cord [18] can make the blade action, realizes shearing work.With reference to shown in Figure 4, when making turnover arm [16] and stock [15] when being connected in vertical state, then the shear surface of scissors and stock [15] are parastate, and the people one hands stock [15] on ground at this moment, on the other hand spur stay cord [18], can shear the limb that high aerial and ground is parallel direction easily; With reference to shown in Figure 5, when making turnover arm [16] and stock [15] be the 45 state to be connected, then the shear surface of scissors and stock [15] are the 45 state, can shear easily at this moment height in the air and ground be the limb of 45 ° of left and right sides angles; With reference to shown in Figure 6, when making turnover arm [16] and stock [15] be parastate to be connected, then scissor cut face and stock [15] at this moment, can be sheared height and the perpendicular limb in ground in the air in vertical state easily.

Claims

1. the high altitude scissors of a changeable angle, include the stay cord [18] of the scissors formed by two blades [11], [12] and stock [15], pulling scissors and can make two blades be the spring [17] of normally open, it is characterized in that: the blade of scissors [11] shank is connected with one of turnover arm [16] end, and the other end of turnover arm [16] is connected with stock [15]; Hanging spring [17] on the another blade [12] of scissors links with turnover arm [16], pommel in blade [11], [12] is equipped with assembly pulley [13], go up installation pulley [14] at turnover arm [16], stay cord [18] is wound on earlier on the assembly pulley [13], again around descending to pulley [14].

2. by the high altitude scissors of the described a kind of changeable angle of claim 1, the arm [16] that it is characterized in that transferring is to be fixedly installed in blade [11] shank in vertical state with the scissor cut face.
