Press and slide the side end of the piston rod 6 to squeeze the spring 29, then slide the piston rod 6 horizontally. After the piston rod 6 slides to adjust the air pressure inside the air pressure groove 11, release it so that the lower end of the positioning block 10 slides into the interior of the base 1 under the pressure of the spring 29 to fix it, and then slide in the high-precision gear.
