Abstract

A mechanism for cutting driving of a lopper comprises an operating lever (1), a movable sleeve (3), a drive shaft (6) and a drive connection shaft (9). The drive shaft (6) is mounted on an inner side of the operating lever (1). A retaining ring (10) is mounted at a lower end of the drive shaft (6). The drive connection shaft (9) on a lower side of the drive shaft (6) is connected to an inner wall at a lower end of the operating lever (1). A gear (8) is fixedly connected to an upper end of the drive connection shaft (9). A bolt (2) is vertically mounted in a protruding portion on a right side of the operating lever (1). The movable sleeve (3) is mounted outside the operating lever (1) and wraps the operating lever (1). A fork block (4) is horizontally mounted at a lower end on a right side of the movable sleeve (3). The fork block (4) runs through a slot-shaped through hole (13), and is urged against a lower edge of a step on a side of the retaining ring (10). The structure is simple in structure, makes operation convenient, and can rapidly cut the drive line of a lopper to immediately stop a cuter working.

Description

Driving circuit breaking mechanism of high branch shear

3⁄4 field

The utility model relates to a safety protection mechanism of a high branch shear, in particular to a drive breaking mechanism of a high branch shear. Background technique

High-pruning shear is the most commonly used agricultural machinery. During use, high-cutting shears can work at various working angles, regardless of the working angle at work, if the cutting knives are still running. When you stop, the cutter does not stop immediately, which is prone to accidents.

Summary of the invention

The technical problem to be solved by the utility model is to provide a driving circuit breaking mechanism of a high branch shear, which has a simple structure and convenient operation, can quickly cut off the driving circuit of the high branch shear, and immediately stops the cutting knife.

The technical solution adopted by the utility model to solve the technical problem thereof is: providing a driving circuit breaking mechanism of a high branch shear, comprising an operating rod, a movable outer casing, a driving shaft and a driving connecting shaft, wherein the driving shaft is mounted on the operating rod through a bearing An inner side, a lower end of the drive shaft is mounted with a retaining ring, and a driving connecting shaft on a lower side of the driving shaft is connected to an inner wall of a lower end of the operating rod through a bearing, and the upper end of the driving connecting shaft is fixedly connected with a gear, The protruding portion on the right side of the operating rod is vertically installed with a latch, and the outer side of the operating rod is wrapped with a movable outer casing, and the right side lower end side wall of the operating rod is vertically opened with a word through hole. The lower end of the right side of the movable outer casing is laterally mounted with a fork block, and the fork block passes through a straight through hole at a lower edge of a side step of the retaining ring.

The lower end of the retaining ring is provided with an internal gear matched with the gear.

A spring is mounted on the outer side of the drive shaft.

A return spring is disposed between the latch and the operating rod, and the lower end of the latch passes through the movable outer casing to be inserted into the jack seat mounted at the lower end thereof.

Beneficial effect

The utility model relates to a driving circuit breaking mechanism of a high branch shear, which has a simple structure and convenient operation. The fork mechanism is used to realize the disengagement between the driving shaft and the connecting shaft, thereby cutting off the driving circuit, and the driving circuit of the high branch shear can be cut off quickly, so that the cutting knife is immediately Stop running.
