Description

Technical Field

[0001] The invention relates to the technical field of gardening and forestry, in particular to a pair of high-branch shears used for pruning trees. Background Art

[0002] Pruning branches is a necessary part of greening work. Pruning branches can make the tree shape beautiful, make the flowers or fruits get more nutrients, reduce pests and diseases, and promote the remaining branches and leaves to thrive. There are many types of tools for pruning trees, which effectively reduce the difficulty and time of pruning for workers.

[0003] At present, the operation mode of using high branch shears when pruning trees is mostly to pull the rope, and the pulling distance of the rope is long, which is time-consuming and laborious.

[0004] Therefore, based on the above problems, a pair of high-branch shears for pruning trees is proposed. This solution can effectively solve the problem of time-consuming and labor-intensive use of high-branch shears when pruning trees, improve the quality and appearance of pruning, improve pruning efficiency, and save time and effort. Summary of the invention

[0005] The present invention is intended to provide a high-branch shear for pruning trees, so as to solve the problem that the operation mode of using high-branch shears for pruning trees in the prior art is mostly to pull a rope, which has a long pulling distance and is time-consuming and labor-intensive.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The technical solution provided by the present invention is: a high-branch shear for pruning trees, comprising a rod body, a fixing device is arranged above the rod body, a cutting device is movably arranged on one side of the fixing device, a return spring is fixedly arranged above the cutting device, a transmission device is embedded under the rod body, a limiting rope is movably arranged on one side of the rod body, and a transmission rope is fixedly arranged on one side of the rod body;

[0008] The transmission device includes a first sleeve which is embedded and installed under the rod body. A transmission plate is fixedly provided on one side of the first sleeve. A transmission ring is fixedly provided at one end of the transmission plate. A transmission shaft is movably provided in the transmission ring. Transmission clamps are movably provided at both ends of the transmission shaft. A second sleeve is fixedly provided at one end of the transmission clamp. Several pulleys are evenly provided on one side of the second sleeve and the first sleeve, and the pulleys are movably connected to the transmission rope.

[0009] Furthermore, a connecting rod is fixedly provided above the rod body, the connecting rod is snap-connected to the rod body, a connecting ring is fixedly provided on one side of the connecting rod, a connecting shaft is movably provided in the connecting ring, a connecting plate is fixedly provided on the other side of the connecting rod, and a connecting groove is opened on one side of the connecting rod.

[0010] Furthermore, the fixing device comprises a fixed cutting knife bolted in the connecting plate, a fixed shaft is movably arranged on the surface of the fixed cutting knife, a fixed plate is fixedly arranged on one side of the fixed cutting knife, and a fixing groove is arranged on the surface of the fixed plate.

[0011] Furthermore, the cutting device includes a cutting blade movably mounted on the surface of the fixed shaft, a cutting plate is symmetrically arranged on the surface of the cutting blade, a cutting rod is bolted to one end of the cutting plate, a cutting block is fixed to one end of the cutting rod, a cutting groove is fixed below the cutting block, a cutting shaft is arranged in the cutting groove, and a cutting ring is fixed above the cutting block.

[0012] Furthermore, one end of the reset spring is fixedly connected to the cutting ring, and the other end of the reset spring is fixedly connected to the fixing groove, so that the cutting blade can be reset by the elastic restoring force of the reset spring after each use, which is convenient for the next trimming work.

[0013] Furthermore, one end of the limit rope is fixedly connected to the connecting shaft, and the other end of the limit rope is fixedly connected to the cutting shaft, so as to limit the maximum reset distance after each reset spring is reset.

[0014] Furthermore, one end of the transmission rope is fixedly connected to the connecting groove, and the transmission rope movably passes through the cutting shaft and is fixedly connected to the pulley. The transmission rope is connected to the pulley by judging according to the length of the transmission rope. The longer the transmission rope is, the more pulley groups are connected, and vice versa, thereby preventing the transmission rope from being too long to affect trimming.

[0015] The beneficial effects of this technical solution are:

[0016] (1) To ensure that the pruning work can be carried out through the transmission device and to prevent the transmission rope from being too long to affect the pruning efficiency;

[0017] When in use, the first sleeve is embedded and installed at one end of the rod body to fix it, and one end of the transmission rope is fixedly connected to the connecting groove, and then the other end of the transmission rope is connected to the pulley through the cutting shaft in the cutting groove for staggered active connection. The number of connected pulley groups is related to the length of the transmission rope. The longer the remaining length of the transmission rope is, the more pulley groups are connected. After the transmission rope is connected, the first sleeve is held and the second sleeve is pressed to adjust the second sleeve according to the transmission shaft. The transmission shaft rotates in the transmission ring, so that the angle adjustment of the second sleeve drives the transmission rope on the pulley surface to move, so that the transmission rope drives the cutting blade at one end to adjust the angle, so that the cutting blade contacts the fixed cutting blade to complete the trimming work. After loosening the second sleeve, the reset spring drives the cutting blade to reset according to its own elastic restoring force, and resets the second sleeve by driving the position of the transmission rope. The limit rope can limit the maximum reset distance of the reset spring. BRIEF DESCRIPTION OF THE DRAWINGS
