Document Type and Number:
Japanese Patent JP2016203355
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a scraper, in which during cutting, chips are prevented from getting entangled with the scraper and a pipe so as to allow fusion between the pipe and a joint to be secured and a blade to be moved with comparatively small force.SOLUTION: A scraper 1 comprises a scraper main body 11 having an insertion hole 13 into which an end part of a pipe P can be inserted formed therein and a blade 21 having a cutting blade 21C for cutting an outer peripheral surface ES of the end part of the pipe, which cuts the outer peripheral surface of the end part of the pipe by rotating the scraper main body around a center shaft line CL of the pipe while pressure-contacting the cutting blade of a blade with the outer peripheral surface of the end part of the pipe inserted into the insertion hole. The scraper further comprises a cover 31 which moves between a close position where the cutting blade of the blade is covered from outside of the scraper main body and an open position where the cutting blade of the blade is exposed to outside the scraper main body, where a space S for storing chips of the pipe is formed between the blade and the cover when the cover is at the close position.SELECTED DRAWING: Figure 3
