Description

TECHNICAL FIELD

[0001] The utility model relates to electric tool technical field especially, it relates to a knife handle. BACKGROUND

[0002] In prior art, when using drill bit to punch or tap, it is easy to punch off, and the process of punching or tapping is easy to break tap tool, which will aggravate the wear of reamer, and the current market has only axial or radial single direction offsetable knife handle for tapping. SUMMARY

[0003] In order to overcome the above-mentioned defects of prior art, the utility model provides a knife handle to solve the problems in the background art, reduce the wear of tool and improve the service life of tool.

[0004] In order to realize the above-mentioned utility model purposes, the utility model provides a knife handle, which comprises a knife handle main body for connecting with external equipment, a collet handle for setting tool, and a flexible connecting piece capable of rotating the collet handle by a certain angle relative to the knife handle main body.

[0005] Further, the flexible connecting piece is a bellows type shaft coupling.

[0006] Further, the collet handle is an ER collet handle.

[0007] Further, the tool is a tapping tool or reamer.

[0008] Compared with prior art, the utility model has the beneficial effects that:

[0009] By setting flexible connecting piece, the knife handle main body installed on electric drill and the collet handle for setting tool are bent by a certain angle, which can adapt to the offset of tool during tapping or punching, avoid rapid wear or breakage of tool, and improve the service life of tool. BRIEF DESCRIPTION OF DRAWINGS

[0010] Figure 1 It is the structural schematic diagram of the utility model embodiment. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme in the utility model embodiment will be described clearly and completely in combination with the drawings of the utility model, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. The embodiment of the utility model will be described in combination with the drawings.

[0012] As Figure 1As shown, a tool holder, comprising a tool holder body 1 for connecting with external equipment, a chuck handle 3 for setting a tool 4, the tool holder body 1 and the chuck handle 3 are connected through a flexible connecting piece 2 which can rotate the chuck handle 3 relative to the tool holder body 1 by a certain angle, by setting the flexible connecting piece 2, the tool 4 and the tool holder body 1 can rotate by a certain angle, better adapt to punching or tapping, the tool holder body 1 is connected and installed with the electric drill and the like, under the driving of the electric drill, the tool is rotated to tap or punch;

[0013] The flexible connecting piece 2 is a bellows type coupling, which can rotate by a certain angle, meets the use requirements, and can be purchased between, is more convenient to obtain, and is convenient for popularization and use;

[0014] The chuck handle 3 is an ER chuck handle, which can be directly purchased on the market, and is easy to obtain;

[0015] The tool 4 is a tapping tool or a reamer, so as to tap or punch through the tool holder connected equipment;

[0016] By setting the flexible connecting piece 2, the tool holder body 1 installed on the electric drill and the chuck handle 3 setting the tool 4 are bent by a certain angle, which can adapt to the deviation of the tool during tapping or punching, avoid rapid wear or fracture of the tool, and improve the service life of the tool.

[0017] The technical scheme of the utility model is described above in combination with specific embodiments, but it should be noted that the above description is only for explaining the scheme of the utility model, and cannot be explained as the specific limitation of the protection scope of the utility model in any way. Based on the explanation here, other specific embodiments or equivalent substitutions of the utility model which can be thought of by those skilled in the art without creative labor will fall into the protection scope of the utility model.
