A force-optimized and stable hand saw

Abstract

The invention relates to the field of tool devices, in particular to a stress-optimized stable handsaw. According to the technical scheme for achieving the stress-optimized stable handsaw, a handle comprises a reinforcing sleeve for a user to hold, and the reinforcing sleeve sequentially comprises a main inner layer made from a hard material, an elastic layer supported by a soft material and an adsorption layer arranged outside the elastic layer and made from a water adsorption material from inside to outside; multiple buffer parts for buffering pressure are arranged between the main inner layer and the elastic layer and are annularly arranged, the middles of the buffer parts are provided with internally sunken deformation grooves internally sunken in a circular-arc-shaped mode, and multiple massaging balls are arranged on the side, facing the adsorption layer, of the elastic layer. The stress-optimized stable handsaw has the high degree of fitting with the hand of a worker, the stability of a moving trail of the saw in the saw pushing process is strengthened, security coefficients are improved, an inner layer of the handle is specially treated, the durability is high, and the human comfort degree is also high.

Description

technical field [0001] The invention relates to the field of tool equipment, in particular to a stable hand saw with optimized force. 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.

AI Technical Summary

Problems solved by technology

[0003] However, this structure still has certain shortcomings. The use of the hand saw is completely dependent on manual cutting. With exhaustion, the cutting action will be deformed, and the trajectory of the push saw will be deviated. On the one hand, the cutting section will be uneven. On the other hand, paddling or even dropping hands will occur, causing potential safety hazards

[0004] In addition, due to the long-term push saw action, there will be many problems in the handle part of the hand saw, such as hand sweat, slippery hands, and the handle is hard to hold. Discomfort and injury to the opponent
