A high-altitude pruning saw

Abstract

The invention discloses an aloft pruning saw. The aloft pruning saw comprises a circular saw blade, a Y-shaped driving rod and a pawl. The circular saw blade and a ratchet wheel are fixedly connected through a key pin. The circular blade and the ratchet wheel are fixed to the middle of a bearing rod. The bearing rod is fixed in a claw-fork-shaped fixing rod through a bearing. The top ends of the Y-shaped driving rod are fixed to the two ends of the bearing rod. The Y-shaped driving rod and a driving rod are welded and connected. The top end of the pawl and the top end of the driving rod are movably connected through a connection column. The tail end of the pawl is erected on wheel teeth of the ratchet wheel. The tail end of the driving rod is fixedly connected with the bearing rod. By means of the aloft pruning saw, according to the lever principle, the circular saw blade can be rotated by pressing and pulling a second operation rod, and therefore the saw-cutting pruning function is achieved; in addition, the ratchet wheel is arranged, and therefore the saw blade can be rotated in one direction, and the cutting pruning efficiency is improved; in addition, the whole saw is simple in structure, easy to operate, convenient to carry and suitable for being used in various severe environments.

Description

Technical field [0001] The invention relates to the technical field of outdoor machinery and equipment, in particular to a high-altitude pruning saw. Background technique [0002] When pruning impurities in trees, garden workers must use garden saws for pruning. It is the current garden saw with a single function. When people use a saw to operate, they hope to save more effort. The prior art garden saw includes a saw blade and a main body. The saw blade and the main body are connected by screws. The angle between the saw blade and the main body is between 120 degrees and 150 degrees; There is a handle, but this kind of saw is not convenient for people to operate, and in the process of sawing, it will still consume a lot of physical strength, which can easily cause arm soreness for a long time. [0003] There are still many electric saws that use electric power on the market. The electric saw is very economical. However, in the prior art, the electric circular saw is composed of a ...

Problems solved by technology

[0002] When garden workers trim the impurities of trees, they must use garden saws for trimming. It is the current garden saw with a single function.

When people operate with a saw, they hope to save more labor, and the garden saw of the prior art includes a saw blade and a main body, the saw blade and the main body are connected by screws, and the included angle between the saw blade and the main body is between 120 degrees and 150 degrees; There is a handle, but this kind of saw is not convenient for people to operate, and it still consumes a lot of energy during the sawing process, which can easily cause arm pain for a long time

[0003] There are also many power saws driven by electricity in the market. The power saw is very convenient. However, in the prior art, the electric circular saw is composed of a handle and a circular saw blade. A motor that drives the circular saw blade to rotate is arranged in the handle. You can directly hold the handle, but this kind of electric saw is only suitable for use in places with electricity, and cannot be operated in deep mountain gardens. Therefore, we urgently need to design a saw to solve this problem
