A cleaning handsaw

Abstract

The invention relates to the field of tools and equipment, in particular to a cleaning arm saw. According to the technical scheme, the cleaning arm saw comprises a saw frame, a saw blade installed on the saw frame, and a grab handle connected with the saw frame; the cleaning arm saw further comprises a cleaning device which comprises an articulated pipe connected with the saw frame, and a main plate which is connected with the articulated pipe and can overturn relative to the saw frame; and a wind power unit is arranged on the main plate and comprises a strong wind device and a slow wind device located below the strong wind device, the strong wind device comprises a plurality of strong wind outlet pipes, the slow wind device comprises a slow wind outlet, and the wind outlet diameter of the strong wind outlet pipes is smaller than the wind outlet diameter of the slow wind outlet. According to the cleaning arm saw provided by the invention, the fit degree to the hand of a worker is high, the stability of the motion track of the saw blade in the saw pushing process is enhanced, and the safety coefficient is increased; and the arm saw is further provided with the cleaning device, so that cutting positions and the saw blade are cleaned efficiently.

Description

technical field [0001] The invention relates to the field of tool equipment, in particular to a cleaning 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 Chinese patent document CN 100546746C discloses a hand saw that can be dismounted after the announcement. The connection mode between the saw blade and the operation has been optimized, 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. With e...

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
