An outer wall portion is connected to one of the twosidewalls 4215 of theprotection member 42 and includes an adjustinghole 4217 via which a head of the adjustingscrew 428 is accessible. Therefore, as shown inFIG. 7 , theholding member 423 can be adjustably moved along the adjustingscrew 428 when rotating the adjustingscrew 428. By the adjustment of theholding member 423, the laser beam can be precisely set relative to the rotatingblade 30. Ahood 426 has a first end fixed to the second end of theprotection member 42 by a screw extending through a hole in thehood 426 and connected to a threadedhole 4219 in the second end of theprotection member 42. A second end of thehood 426 includes a slot 4262 (FIG. 4 ) defined in an inside thereof so as to receive another part of thelens 427 which is then well positioned. Aprotrusion 4261 extends from one of two sides of thehood 426 and positions a plain section of the distal end of the adjustingscrew 428 in thenotches 4218. Thetube 424 and the laser generatingpiece 425 are covered by thehood 426. - A
fence assembly 50 is composed of afirst fence 51 and asecond fence 52. Thefirst fence 51 is a U-shapedmember 511 and has a first end thereof pivotably connected between the twosidewalls 4215 of theprotection member 42. Thefirst fence 51 is located above the rotatingblade 30. Afirst recess 513 is defined in the first end of thefirst fence 51 and afirst pin 515 extends through two sides of thefirst recess 513 and the twosidewalls 4215 of theprotection member 42. A first U-shapedflexible plate 516 is rested in thefirst recess 513 and positioned by thefirst pin 515. One of two sides of the first U-shapedflexible plate 516 contacts against anupright wall 4214 in thefirst end 421 of theprotection member 42 and the other one of the two sides of the first U-shapedflexible plate 516 contacts against an upright inside 514 of thefirst recess 513. The first end of thefirst fence 51 has afirst stop surface 512 which contacts against theupright wall 4214 in thefirst end 421 of theprotection member 42 so as to prevent thefirst fence 51 from being pivoted downward. - The
second fence 52 is a U-shapedmember 521 and has a first end thereof pivotably connected between the twosidewalls 4215 of the second end of theprotection member 42. Aprotrusion 527 extends from an inside of a second end of thesecond fence 52 and asecond end 517 of thefirst fence 51 is rested on theprotrusion 527 of thesecond fence 52 when thesecond fence 52 is pushed upward by atile 60 as shown inFIG. 5 . Asecond recess 523 is defined in the first end of thesecond fence 52 and asecond pin 525 extends through two sides of thesecond recess 523 and the two sidewalls of theprotection member 42. A second U-shapedflexible plate 526 is rested in thesecond recess 523 and positioned by thesecond pin 525. One of two sides of the second U-shapedflexible plate 526 contacts against anupright wall 4213 in second end of theprotection member 42 and the other one of the two sides of the second U-shapedflexible plate 526 contacts against an upright inside 524 of thesecond recess 523. The first end of thesecond fence 52 has asecond stop surface 522 which contacts against theupright wall 4213 in thefirst end 421 of theprotection member 42 so as to prevent thesecond fence 52 from being pivoted downward. Therefore, when atile 60 is put on thetop surface 21 of the tile cutting machine, a laser beam “L” as shown inFIG. 6 is marked on thetile 60 and theblade 30 cuts thetile 60 along the laser beam “L.”. The second end of thesecond fence 52 is raised upward by the thickness of thetile 60 so that thesecond end 517 of thefirst fence 51 is pivoted upward by the upward pivotal movement of theprotrusion 527 of thesecond fence 52. After thetile 60 is removed, the first andsecond fences flexible plates upright walls - The
fence 52 also covers the opening between thefirst fence 51 and theprotection member 42 to keep debris and cutting liquid or the like from splashing out via the opening. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
