本考案は、ベース上面に対してのこ刃を左右に
傾斜できる卓上切断機の動力伝達機構に関するも
のである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a power transmission mechanism for a table-top cutting machine that can tilt the saw blade from side to side with respect to the upper surface of the base.
従来技術を第５図を用いて説明する。 The prior art will be explained using FIG. 5.
第５図は卓上切断機を右側へ傾斜させた正面図
である。 FIG. 5 is a front view of the table-top cutting machine tilted to the right.
ホルダ５を右側へ傾斜させると、モートルハウ
ジング９は水平方向に突出しているため、被切断
材２の上面にモートルハウジング９の端部が当た
り、切断加工ができなかつた。 When the holder 5 was tilted to the right, the end of the motor housing 9 abutted against the upper surface of the material to be cut 2 because the motor housing 9 protruded in the horizontal direction, making it impossible to cut the material.
従つて、被切断材２を反転させ、のこ刃１９を
左側へ傾斜させて切断しなければならない不便さ
があつた。 Therefore, there is an inconvenience in that the material to be cut 2 must be turned over and the saw blade 19 must be tilted to the left for cutting.
