Novel cleaning hand saw

Abstract

The invention relates to the field of tool equipment, in particular to a novel cleaning hand saw. The novel cleaning hand saw is implemented by the following technical scheme: the novel cleaning hand saw comprises a saw frame, a saw blade mounted on the saw frame and a grab handle connected with the saw frame, and further comprises a cleaning device, wherein the cleaning device comprises an articulated pipe connected with the saw frame and a mainboard connected with the articulated pipe and can turn over relative to the saw frame; a wind power device is arranged on the mainboard; the grab handle comprises a reinforcing sleeve for a user to hold; and the reinforcing sleeve sequentially comprises a main inner layer made of a hard substance, an elastic layer supported by a soft substance and an adsorption layer arranged outside the elastic layer and made of an absorbent material from the inside out. The invention aims to provide the novel cleaning hand saw, which highly fits a hand of a worker, the hand saw further comprises the cleaning device which can be used for efficiently cleaning the cutting parts and the saw blade, and the inner layer of the grab handle is subjected to special treatment, so that the durability is high, and the degree of human comfort is also high.

Description

technical field [0001] The invention relates to the field of tool equipment, in particular to a novel cleaning handsaw. 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. Wit...

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, during the push saw cutting process, there will be debris left on the cutting workpiece and on the saw blade, and these residual chips will affect the operation line of sight on the subsequent cutting push saw, and will also affect the damping of the push saw

Moreover, lubricating oil needs to be added during the cutting process, which brings inconvenience to the operation

[0005] 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
