Horizontal sawing machine

A horizontal sawing machine, comprising:

• a support unit having a slide rail base and two stationary slide rails, wherein the slide rail base has a slide channel extending through a top side and a bottom side of the slide rail base, and the two stationary slide rails are oppositely disposed on the slide rail base, are located on two opposite lateral sides of the slide channel respectively, and extend in a direction parallel to a direction in which the slide channel extends;
• a driving unit having a driving motor, a reducing gear box, and two movable slide rails, wherein the driving motor is located above the slide rail base of the support unit, the reducing gear box is connected to the driving motor and has an output shaft extending into the slide channel of the slide rail base of the support unit, and the two movable slide rails are oppositely disposed on an outer periphery of the reducing gear box and are respectively and slidably engaged with the stationary slide rails of the support unit in order for the driving unit to move with respect to the support unit;
• and
• a sawing unit provided under the slide rail base of the support unit and having a saw blade mount and a saw blade, wherein the saw blade mount is connected between the output shaft of the reducing gear box of the driving unit and the saw blade in order for the saw blade to move along with the driving unit and be driven to rotate by the driving unit.
