Example (b):

as shown in fig. 1, the utility model comprises a connecting block 1, a groove-shaped frame 2, an outer guide rod 3, an inner guide rod 4, a screw 5, a roller 6 and a motor output shaft 7. The roller 6 is placed in the groove-shaped frame 2, and the motor output shaft 7 is connected with the roller 6 through the connecting block 1 to drive the roller 6 to do circular motion; the inner guide rod 4 is fixed inside the outer guide rod 3 through a bolt, the outer guide rod 3 is fixed on the right side of the groove-shaped frame 2 through a screw 5, and the outer guide rod 3 and the inner guide rod 4 are placed on the same side of the groove-shaped frame 2, so that the space is reduced, and the structure is more compact; the outer guide rod 3 is provided with a low-pressure piston ring, and the inner guide rod 4 is provided with a high-pressure piston ring for being matched with an air compressor; the number of the screws 5 is two, so that the outer guide rod 3 can be fixed better; the groove-shaped frame 2 is vertical to the inner guide rod 4, and converts the circular motion of the roller 6 into the reciprocating linear motion of the inner guide rod 4; the motor output shaft 7 is positioned on the horizontal symmetrical shaft of the groove-shaped frame 2, so that the utility model is more stable in the working process; the length of the inner guide rod 4 is less than that of the outer guide rod 3; the two vertical inner walls of the groove-shaped frame 2 are tangent to the roller 6 all the time, so that the roller 6 moves more stably; the horizontal symmetry axis of the inner guide rod 4 and the horizontal symmetry axis of the motor output shaft 7 are positioned on the same horizontal line.
