Description

Portable low vibration aerial saw

The present invention relates to a portable low-vibration high-speed saw, in which work fatigue is remarkably improved due to its light weight, and the saw blade is supported by a blade formed with a thinner thickness than the saw blade, so that the cutting range is extended without interference with the size and depth of the workpiece. , It relates to a portable low-vibration high-speed saw that can effectively offset vibration while a multi-rod member that transmits a linear reciprocating force required for sawing is linearly reciprocated in opposite directions by a rack and a pinion.

In general, a saw is a device that has sharp teeth on a thin saw made of steel, and cuts a cutting object including a tree with sharp teeth by a linear reciprocating force in the longitudinal direction. Although it is widely used for high-altitude work including business, it takes a lot of power to manually saw a workpiece from a distance and it is impossible to work for a long time.

Accordingly, in Patent Registration No. 10-1129771 disclosed in the prior art, a power generating device for generating power and a power transmitting means such as an electric wire, a housing, and a motor driven by receiving power from the power generating device inside the housing and a drive shaft that rotates in conjunction with the motor and transmits rotation by forming a worm gear on the other side, an eccentric cam installed inside the housing, a rod part coupled to the cam part of the eccentric cam and transferred in a straight line, and at the end of the rod part a transfer gear provided; a fixed rack gear fixed inside the housing to couple the transfer gear in a gear meshing shape; a driving body positioned horizontally apart from the fixed rack gear and driven back and forth by the transfer gear; It is composed of a saw blade installed in the front of the driving body, and a technology configured to obtain sufficient driving force and stroke of the blade by a small amount of power has been previously registered.

However, in the prior art, the motor rotational force is converted into a linear reciprocating motion by the eccentric cam and the rod part to transfer the saw blade, but the saw blade, the motor driving the saw blade, and the driving body for converting the rotational motion into a linear motion are integrated. As it is formed and installed at the end of the support, the center of gravity is concentrated on the end of the support where the saw blade is installed, so that when the operator holds the other end of the support and sawing at high altitude, a lot of force is required and fatigue is increased.
