A cutting worktable includes a worktable body have a distal side located away from a cutting tool and a proximal side located adjacent to the cutting tool. The cutting worktable further includes a support frame assembly disposed at the proximal side of the worktable body and used to lift an object to be cut so that the object to be cut is placed on a top surface of the worktable body in an inclined posture. The support frame assembly includes a support roller for contacting the object to be cut and the worktable body is provided with a limiting structure for abutting against the object to be cut and limiting its position. The object to be cut can thus be inclined via the support frame assembly and fixed by the limiting structure. The limiting structure can be in the form of a plurality of placement grooves to achieve placement of the object to be cut at different angles relative to the cutting tool and worktable.
