The neck that top is arc is formed between revolver profile surface, without sharp sharp part, the neck of arc carries out chamfering, power using friction
Degree is gentle, and protection cable other parts are injury-free, while can also improve the degree of accuracy and the operating efficiency of chamfering.
Preferably, using neck top as starting point, to the second extension bottom distance h with to the first extension bottom
Distance H ratio is：1:2.Such ratio enables the first extension in chamfering preferably to provide power for the first extension
Support, rapid operation efficiency high.
The revolver profile surface of first extension is plane so that whole chamfering device entirety weight distribution is more balanced.
The handle portion is cylinder, convenient crawl and work.
The handle portion is preferably provided with tread plate, is advantageous to improve job security.
The handle portion has suppending hole in end set.The not used time, by suppending hole suspension on the wall, be advantageous to take care of.
The work department is integrally formed with handle portion.The intensity of chamfering device can be strengthened, it is more firm, it is durable.
The chamfering device is made of metal or metal alloy, preferentially selects copper or aluminium alloy.
Compared with prior art, the utility model has the following advantages that and beneficial effect：
1st, neck is designed using top curve, without sharp sharp part, can protect cable not well simultaneously in chamfering
Damaged by other；
2nd, the design of neck and metal sheath clearance distance and chamfering angle size match, the second extension as insertion end,
Its right wheel profile surface is cambered surface, and revolver profile surface is plane, it is easy to is inserted between metal sheath and cable insulation, convenient operation；
3rd, it can utilize during chamfering and be supported outside metal sheath, it is now right with the first extension of metal sheath external contact
Contoured surface is also cambered surface, and whole metal sheath is in the protection of chamfering device, protects cable well, makes cable from damage
Wound；
4th, operation is more convenient, can greatly improve cable metal sheath chamfering efficiency of construction.
