Lithium-ion chain saw containing cubic parabola for reducing impact

Abstract

The invention provides a lithium-ion chain saw containing a cubic parabola for reducing impact. The lithium-ion chain saw comprises a machine body (127) with a wedge, a machine cover (127a) with the wedge, and a following chain saw bracket (128) with the wedge and the cubic parabola; the wedges are hollow hexagonal pyramid bodies (131) with small through holes (131a) formed in the top parts; a sound absorbing piece (131c) is adhered on the bottom surface of each hollow hexagonal pyramid body with the small through holes; a plurality of micro pores (131f) in the sound absorbing pieces are respectively corresponding to the small through holes, and thereby, a muffling and noise reducing cavity is formed; with the adoption of the muffling and noise reducing cavity, noise flowing into the micro pores is compressed into a muffling cavity of each hollow hexagonal pyramid body to be expanded and then is discharged through small through holes; a vibration absorbing handle (133) is arranged at the outer part of the machine body; a foam polyurethane pipe sleeves a hollow plastic pipe by the method of extending a compressed air gun in a gap between the plastic pipe and the foam polyurethane pipe to feed as blowing; the curvature of the cubic parabola at point (0, 0) is known as zero, the same to the curvature of a straight line; a function bracket strip (128d) containing the cubic parabola of the following chain saw bracket is manufactured through spring steel plates by normalizing heat treatment.

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 garden places such as courtyards and sidewalks. It is a light portable and improved electric tool, also known as a lithium electric chain saw with a cubic parabola to reduce impact. 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...

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
