Abstract

The utility model relates to a pruner for pruning tall branches. An upper knife head is arranged on the head part of a main knife rod, and a supporting point clamp is fixed on the main knife rod, wherein, the main knife rod is a hollow round tube with thin wall, and an inner push rod is sheathed inside the main knife rod; the head part of the inner push rod is provided with a lower knife head, and the tail part of the inner push rod is provided with a plug. A lever provided with a cam is connected with the supporting point clamp through a shaft. When the utility model is used, the lever is wrenched to drive the cam to rotate so as to drive the inner push rod to move upward under the action of the cam, and the lower knife head squeezes branches to the upper knife head, so that the branches are pruned under the pruning of upper and lower cutting edges. The utility model has the advantages of unique structure, convenient operation, labor saving, high safety without climbing high for operation, etc., and can be widely used for orchards and forestry departments.

Description

A kind of high-order hand-bill

The utility model relates to the specific purpose tool of a planting fruit-trees and trees beta pruning use, specifically is a kind of high-order hand-bill.

In the prior art, people are used for pollard or fruit tree branch, generally all are manually by ladder, stool or climb up by holding on to trees and use the scissors complete operation, the effort of not only taking a lot of work, and operation inconvenience, and inefficiency are absolutely unsafe.

The purpose of this utility model solves above existing in prior technology problem with regard to being, a kind of structure uniqueness is provided, and is easy to operate, saves labor high efficiency, the high-order hand-bill of the safe and reliable and operation of need not climbing to a higher point.

The purpose of this utility model realizes by following measure.A kind of high-order hand-bill, comprise the connection clamp, axle, lever, rivet, guide finger, operator bar and the last cutter head that is located at the operator club head, last cutter head is fixedly connected by connecting clamp and rivet and operator bar, the operator bar is a hollow thin-wall pipe, one slotted hole is arranged on it, interior top stem casing is contained in the hollow tube chamber of operator bar, the head of interior push rod is provided with down cutter head, afterbody is provided with stopper, guide finger is located at the slotted hole place of operator bar, and be fixedly connected with interior push rod, the cutting edge of cutter head and the cutting edge of last cutter head are consistent, and the fulcrum clamp is fixedly mounted on the operator bar, and axle is installed on the fulcrum clamp, the lever that is provided with cam links to each other with the fulcrum clamp by axle, and grip is equipped with in the bottom of lever.

The described cutter head of going up adopts circular arc cutting edge or v shape cutting edge.

Described operator bar, interior push rod all adopt rigid material to make.

Figure is further described the utility model below in conjunction with bowing.

Structural representation when Fig. 1 is the utility model high position hand-bill closure.

Structural representation when Fig. 2 opens for the high-order hand-bill of the utility model.

Fig. 3 is the high-order hand-bill end view of the utility model.

Label declaration:

1, branch 2, go up cutter head 3, connect clamp 4, operator bar 5, fulcrum clamp 6, split pin 7, rivet 8, cutter head 9, stopper 10, cam 11, axle 12, lever 13, grip 14, rivet 15, interior push rod 16, guide finger down

As Fig. 1～shown in Figure 3, last cutter head 2 is located at the head of operator bar 4, and is fixedly connected with operator bar 4 by connecting clamp 3 and rivet 14, last cutter head 2 employing circular arc cutting edges.Operator bar 4 is a hollow thin-wall metal circular tube, and a slotted hole is arranged on it.Operator bar 4 can be selected different length as required.Push rod 15 in the hollow pipe cavity inner sleeve of operator bar 4 is equipped with, the head of interior push rod 15 is provided with down cutter head 8, and afterbody is provided with stopper 9, and guide finger 16 is located at the slotted hole place of operator bar 4, and is fixedly connected with interior push rod 15.By regulating guide finger 16 is that push rod 15 moves up and down in the tube chamber of operator bar 4 in the controlled, and the cutting edge that makes down cutter head 8 keeps direction consistent with the cutting edge of last cutter head 2 under the effect of guide finger 16.Fulcrum clamp 5 is fixed on the operator bar 4 by split pin 6, rivet 7, axle 11 is installed on the fulcrum clamp 5, the lever 12 that is provided with cam 10 links to each other with fulcrum clamp 5 by axle 11, and lever 12 is that fulcrum rotates with axle 11, and grip 13 is equipped with in the bottom of lever 12.Because the ratio of the moment that moment that the work done point of lever 12 and axle are 11 and cam 10 work done points and axle are 11 makes down the shearing force of cutter head 8 increase several times.The circular arc cutting edge of last cutter head 2 can make the branch of being wiped out be in best clipped position exactly.During operation, pull lever 12, drive cam 10 and rotate, push rod 15 moves upward under the effect of cam 10 in making, and following cutter head 8 presses to cutter head 2 with branch 1, about under the shearing of blade, branch 1 is cut off.

The characteristics of the utility model maximum are the operations of need not climbing to a higher point, can be easily with the high-order branches of trees Bar is cut off. Have the structure uniqueness, easy to operate, save labor, high efficiency, safe and reliable, The advantage such as practical can be widely used in orchard and forest department and use.
