Abstract

The invention relates to the field of tool equipment, in particular to a durable balanced hand saw. The present invention is achieved through the following technical solutions: a force-balanced hand saw, comprising a saw frame, a saw blade mounted on the saw frame, and a handle connected to the saw frame, the handle contains a The reinforcing sleeve for holding, the reinforcing sleeve includes the main inner layer made of hard material, the elastic layer supported by soft material and the absorbent layer made of water-absorbing material arranged outside the elastic layer from the inside to the outside ; Between the main inner layer and the elastic layer, there are buffer pieces for buffering pressure, and there are multiple buffer pieces, which are arranged in a ring. The internal fit is high, which enhances the stability of the moving track of the saw blade during the push saw process and improves the safety factor. Part of the force of the hand saw is transferred to the shoulder to relieve hand fatigue. The inner layer of the handle is specially treated for high durability. Human body comfort is also high.

Description

technical field [0001] The invention relates to the field of tools and equipment, in particular to a durable balanced hand saw. Background technique [0002] Hand saws are a common tool because of their lightness, flexibility and ease of use, and have become people's home tools and factory industrial tools. The manual saw includes a bracket, an operating handle and a saw blade. The common structure is the structure disclosed in the Chinese patent document with publication number CN 103878438 A. The saw blade performs sawing and cutting of the object to be processed under the action of human thrust. Another example is a rear detachable hand saw published in Chinese Patent Document No. 100546746C, which optimizes the connection method between the saw blade and the operating unit, making the removal and fastening of the saw blade more convenient. [0003] However, this structure still has certain shortcomings. The use of the hand saw is completely dependent on manual cutting. ...
