Problems solved by technology

There are certain disadvantages in the handle of this structure, not only there are many parts, but also it is not easy to assemble, and it is also bulky and heavy.
When the user uses a cutter to cut the palm tree fruit, it is necessary to assemble the 3-8m long connecting pipe with the handle before use. The user stands under the palm tree and holds the connecting pipe to cut. Due to the diameter of the threaded sleeve If it is too large, it is easy to block the user's sight and is inconvenient to use; moreover, because the bolts and nuts are prone to loosening, in severe cases, the cutter body of the cutter will fall off from the handle, posing a safety hazard

Abstract

The invention relates to a cutting-off tool which is provided with an arc-shaped tool body and a tool handle, wherein the tool body and the tool handle are integrated. A bend which is integrated with the tail portion of the tool handle is arranged at the tail portion of the tool handle. The cutting-off tool is characterized in that a first handle and a second handle cover the periphery of the tool handle, the first handle and the second handle are oppositely combined, the inner side face of the first handle and the inner side face of the second handle are oppositely combined, the upper end of the first handle and the upper end of the second handle are in close fit and fixed through a straining ring, the bend is located on the lower side of the lower end of the first handle or the lower side of the lower end of the second handle, a first groove is formed in the inner side face of the first handle, a second groove is formed in the inner side face of the second handle, the tool handle is arranged in the first groove and the second groove, a plurality of first convex ribs are arranged on the outer side face of the first handle, and a plurality of second convex ribs are arranged on the outer side face of the second handle. The cutting-off tool has the advantages of being simple in structure, high in safety, long in service life and the like.

Description

technical field [0001] In particular, the invention relates to a cutting knife. Background technique [0002] Cutters involved in the present invention mainly include cutters for felling shrubs, trees and palm trees. [0003] The handle of the existing cutting knife includes a sandwich core, a handle sleeve and a threaded sleeve, and the knife handle is arranged in the sandwich core, and the handle sleeve is arranged on the outer periphery of the sandwich core, and is composed of a connecting piece, a plurality of fastening bolts and nuts and a threaded sleeve. The tube securely fits the handle sleeve, core and handle. There is certain shortcoming in the handle of such structure, not only parts are many, and it is inconvenient to assemble, also volume is big, and weight is heavy. When the user uses a cutter to cut the palm tree fruit, it is necessary to assemble the 3-8m long connecting pipe with the handle before use. The user stands under the palm tree and holds the conn...
