A bar 11 of a guide head B having a support bed C attached is fitted in a socket 9 of a support plate 5 and the angle of the support bed C is adjusted to fasten 10 the lever 11. Next, the support bed C is secured fixedly to a frame body and the tension of a spring 19 is adjusted to adjust the abutting force of the scraper 2.
