Abstract
The utility model relates to fruit tree lopping shears which comprise a big fan and a small fan, wherein the big fan and the small fan are both composed of a shear head and a shear handle; axle holes are arranged between the shear heads and the shear handles; the big fan and the small fan are connected by pivots which are penetrated through the axle holes; supporting points, springs and buckles are arranged between the two shear handles. The big fan is positioned on the upper side of the small fan, the blade edges of the shear head of the big fan face to the left side, and the shear handle is positioned on the left side. The small fan is positioned on the lower side of the big fan, the blade edges of the shear head face to the right side, and the shear handle is positioned on the right side of the shear handle of the big fan. The shear body of the big fan of the utility model is arranged on the upper side, and the blade edges of the shear body of the big fan face to the left side. The big fan cuts into twig rods from the right side to the left side when twigs are sheared; cutting edges are enlarged when the twig rods are bent to the left so as not to clamp the shear head, and contrarily, the shear head is favorable to cut into the twig rods. Moreover, the work efficiency is increased. The utility model has the advantages of labor saving and safe operation.
Description
Technical field
The utility model relates to a kind of fruittree shear secateurs, is used for the particularly pruning of fruit tree of forest.
Background technology
From nineteen fifty-two so far, the structure that is used for the scissors of pollard does not change, citation form is an X-shaped, cuts the body and function pivot by two fans and connects and form, two fans are cut body and are divided into big fan and little fan, the haircut broad of big fan, its sword limit is a convex curve and sharp; The haircut of little fan is narrower, its sword limit and the identical sag vertical curve in big fan sword limit, and the effect of little fan haircut mainly is to prop up to be cut thing, it is cut off function and mainly finishes by big fan haircut.Because most users hold with the right hand to cut handle, in this state, the big fan of all existing pruners is positioned at the upside of little fan, and its sword limit is towards the right side, and it is cut handle and is positioned at the right side, and curved to the right.And little fan is positioned at the downside of big fan, and it cuts handle in the left side, and curved to the right.Its sword limit is towards the left side.
When using all existing pruners to carry out pruning, (referring to Fig. 2) left hand generally all holds handsaw 3, in its end hook is arranged.The right hand is held pruner, fans 1 sword limit A greatly at the left side of branch bar 4 an incision branch bar, and left hand with the hook of handsaw with the epimere hook of branch bar 4 to the left side, so that a branch bar of cutting off and will being cut is collected in together.Find out that from Fig. 2 (a) when branch bar 4 bent, the haircut 11 of the big fan of scissors A was clamped at the knife-edge part of branch bar 4 left, this just causes the obstruction to beta pruning, not only requires great effort but also reduced work efficiency.Stick operation if stand in tree, its health will lean against trunk, avoid by poll tongs cutter, needs treedozer branch forward when beta pruning, and it is underground, dangerous that this can may cause the operator to drop.If with the scissors use (as Fig. 2 (b)) that turns over up and down, little fan 2 be positioned at big fan 1 above, because little fan haircut 21 sword limit B are positioned on the otch (promptly big fan A place, haircut sword limit) of a bar 4, when bending, branch bar 4 still produces big resistance left, still clamp big fan, fan 1 greatly and below little fan, also be unfavorable for determining clipped position (bad observation).In addition, two exchanges of cutting handle are used, and hold bad use to asymmetric bad the taking of pruner of cutting handle arranged.
Summary of the invention
The purpose of this utility model just provides a kind of resistance, work efficiency height, fruittree shear secateurs safe in utilization of not producing when beta pruning, reach to save labor, and improves work efficiency, job safety.
The technical solution of the utility model is: a kind of fruittree shear secateurs, comprise big fan and little fan, they are by haircut and cut the handle formation, at haircut and cut axis hole is arranged between the handle, have pivot to pass this axis hole and will fan greatly and little fan connection, cutting at two has the strong point, spring and buckle between the handle, and described big fan is positioned at the upside of little fan, the haircut sword limit of fan is towards the left side greatly, and it is cut handle and is positioned at the left side; Described little fan is positioned at big fan downside, and its haircut sword limit is towards the right side, and it is cut handle and is positioned at the right side that big fan is cut handle.
Be with sleeve on the handle described cutting, anti-skidding line arranged, several grooves that coincide with finger are arranged in the outside of little fan handle cover in the outside of big fan handle cover.
Using method of the present utility model is, to fan greatly when cutting body and placing upside, its sword limit is towards the left side, big fan is cut left from branch bar right side when beta pruning, the branch bar makes the edge of a knife become big when bending left, not only can not clamp haircut, helps the haircut incision on the contrary, improve work efficiency, alleviated labour intensity.
The utility model has the advantages that on fruit tree during beta pruning, former old-fashioned fruittree shear is in order to press from both sides big fan, can only be firmly with the branch bar toward the chest extrapolation, in branch disconnected moment, the people is the easiest to be gone into underground, very dangerous by rolling.When adopting the utility model product not press from both sides big fan, just in time be to draw toward the front, no matter how the branch bar breaks, all fool proof.

Fig. 2 is the schematic diagram of existing pruner when beta pruning, and wherein 2a figure is that forward is taken the situation when holding (promptly fanning at upside greatly), and 2b figure takes the situation of holding (little fan is at upside) conversely;
Fig. 3 is the use schematic diagram of the utility model when beta pruning.
Embodiment
Referring to Fig. 1, fruittree shear secateurs of the present utility model, comprise big fan 1 and little fan 2, they are by haircut 11,21 and cut handle 12,22 formations, axis hole is all arranged between the handle and pass pivot 5 and will fan greatly with little fan and connect with cutting at haircut, cutting at two has the strong point 10, spring 6 and buckle 7 between handle 12 and 22, and the effect of the strong point 10 is to cut the tight spacing point of spindle clamp, the effect of spring 6 is to keep two haircuts to open in use, and the effect of buckle 7 is to cut sleeve together with two when not using pruner.Described big fan is positioned at the upside of little fan 2, and the haircut sword limit A of this big fan 1 is towards the left side, and it is cut handle 12 and is positioned at the left side; Described little fan 2 is positioned at big fan downside, and its haircut sword limit B is towards the right side, and it is cut handle 22 and is positioned at the right side that big fan is cut handle 12.
Cut at described two and all to be with sleeve 121 and 221 on the handle, anti-skidding line 8 is arranged, several grooves 9 that coincide with finger are arranged, hold so that take in the outside of little fan handle cover 221 in the outside of big fan handle cover 121.
Referring to Fig. 3, the utility model will be fanned 1 greatly in use and place upside, its sword limit A is towards the left side, big fan sword A cuts left from branch bar 4 right sides when beta pruning, branch bar 4 makes the edge of a knife become big when bending left, not only can not clamp haircut 11, helps haircut 11 incisions on the contrary, improve work efficiency, alleviated labour intensity.Its effect is obvious.During beta pruning, people's back leans on the trunk of tree in the tree, and the branch of cutting does not press from both sides big fan blade, handling safety toward lira.
