Foldable support frame for supporting cutting machine

A foldable support frame (4) for supporting a cutting machine, the support frame comprising:

• two opposing pairs of leg frames (1,1′) each of which comprises a pair of first and second crossed legs (11,21) pivotally connected together by a connection means (71) and forming a cross pivot point (9,9′) where said first and second crossed legs (11,21) cross, and each first and second crossed leg (11, 21) comprises an upper slide rod (14,24) and a support leg (15,25), an elongate slot (141,241) in each said upper slide rod (14,24);
• a first connection means (12) for supporting said two first crossed legs (11) in parallel manner;
• a second connection means (22) for supporting said two second crossed legs (21) in parallel manner;
• a first support bar (13) fixedly connected between two top ends (16) of said two first crossed legs (11);
• a second support bar (23) fixedly connected between top ends (26) of said second crossed legs (21);
• and
• two opposing stopper means (3,3′) separately mounted respective crossing points (9,9′), wherein each stopper means (3,3′) comprises two side flanges (34) which extend in opposite directions limiting inclination of each of said first and second crossed legs (11,21), a support tab (32) extending from each side flange (34);
• a hole (152,252) on an outer surface (151,251) of each said support leg (15,25), each of said support tabs (32) being inserted into a respective hole (152,252) to support a bottom end (143,243) of a respective upper slide rod (14,24) when said upper slide rods (14,24) are extended until a lower portion (142,242) of each slot (141,241) is impeded by its respective connection means (71) with said first and second crossed legs (11,21) being unfolded and stopped by said side flanges (34).
