Abstract

The invention relates to tool and equipment field, in particular to a durable balanced hack-file. The durable balanced hack-file includes the following technical proposals. The durable balanced hack-file includes a sash, a saw installed on the sash and a handle connecting with the sash. The handle includes a stiffening sleeve, which can be hold by users. The stiffening sleeve, from inside to outside, includes a main inner layer, which consists of hard materials; an elastic layer, which is supported by soft materials; and an absorbed layer, which consists of absorbent materials and is outside the elastic layer. Several bolsters, which are used to buff pressure, are installed in a circle between the main inner layer and the elastic layer. The durable balanced hack-file highly adheres to workers' hands, increases stability of the track of the saw's movement in the process of pushing the saw and improves safety factors. A part of hack-file's stress can be transferred to shoulders, so that hand fatigue can be relieved. Special treatment is carried out on the inner layer of the handle, so that both durability and body comfort are at a high level.

Description

technical field [0001] The invention relates to the field of tool equipment, in particular to a durable balanced hand saw. Background technique [0002] Because of its lightness, flexibility and quick use, the hand saw is a common tool, and it has become a household tool and a factory industrial tool. The manual saw includes a bracket, an operating handle and a saw blade. The common structure is as disclosed in the Chinese patent document 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 that the announcement number is 100546746C, a kind of back detachment hand saw announced in the Chinese patent document, which optimizes the connection mode of the saw blade and the operation, so that the disassembly and fastening of the saw blade become more convenient. [0003] However, this structure still has certain shortcomings. The use of the hand saw is completely dependent on manual cutting. ...
