A lithium electric chain saw with logarithmic spiral for smooth adjustment

Abstract

A lithium electric chain saw provided with a logarithmic spiral for steady regulation comprises a body (127) provided with wedges, a cover (127a) provided with the wedges, a follow-up chain saw stent (128) provided with the wedges and a cubic parabola, wherein each wedge is a hollow hexagonal pyramid (131) with a small through hole (131a) in the top; a sound-absorbing piece (131c) is pasted on the bottom face of the hollow hexagonal pyramid with the small through hole of each wedge; multiple pores (131f) are formed in the sound-absorbing pieces and are in one to one correspondence with the small holes to form sound-absorbing chambers through which noise enters the pores to be compressed into the hollow hexagonal pyramids, and sound-absorbing noise reduction chambers through which noise is expanded and then escapes from the small through holes; a damping handle (133) is arranged outside the body, a foamed polyurethane pipe sleeves a hollow plastic pipe, and the method of sleeving the foamed polyurethane pipe is that a pneumatic gun nozzle with compressed air extends into a pipe gap between the plastic pipe and the foamed polyurethane pipe, and blowing and sleeving are performed simultaneously. As generally known, the curvature of the cubic parabola at the point (0, 0) and the curvature of the line are both zero, and a material of a function stent bar (128d) provided with the cubic parabola of the follow-up chain saw stent adopts a steel spring plate, and is subjected to normalization heat processing.

Description

technical field [0001] The invention relates to a tool that can be used not only for indoor operations in office buildings, but also for gardens such as courtyards and sidewalks. chain saw. Background technique [0002] Large-scale power machines are used, which are huge in size and high in cost. If a sea of ​​people is used, it will be labor-intensive and inefficient. Therefore, various light and small machines have emerged as the times require, and have gradually become popular in institutions, units, schools, parking lots, squares, and property communities It is an essential machine for landscaping that is widely used in many places such as gardens, gardens, and non-motorized lanes. But any product is not perfect, and there are always many deficiencies that need to be further improved. There is noise and vibration in the movement of the machine, and there is a temperature rise, which affects safety and is not up to standard. It is urgent to improve, but it is difficult ...

AI Technical Summary

Problems solved by technology

If there is no need for an engine with exhaust gas emissions, and the electric drive is used on the small machine, it is beneficial to environmental protection; but the electric drive line is very long, which is inconvenient on some terrains
