[0013] 2. The single-screw extruder with heat dissipation function moves the pull plate in the direction away from the fixed frame through the cooperation of the pull plate and the spring, so that the pull plate drives the slide bar to move through the round rod and the square plate until the outer edge of the slide bar is away from the inner wall of the heat dissipation frame, and then the fixed frame is slid on the side of the heat dissipation frame for disassembly, thereby assisting the main filter plate and the auxiliary filter plate to be disassembled and replaced.
