[0008] As a further limitation of the above scheme, the cylinder mounting base and the pressure block support base are adjustable connection structures to accommodate closing springs of different sizes.

[0009] Further defining the above solution, guide rods are provided on both sides of the upper part of the pressure block support base, and the two ends of the guide rods are fixedly supported by guide rod supports. The two sides of the moving pressure block are slidably connected to the guide rods through U-shaped holes.

[0011] Further defining the above scheme, the cylinder is a double-acting cylinder, and its extension and retraction are controlled by a foot pedal valve; when the foot pedal valve is pressed, the cylinder retracts and the dynamic pressure block opens; when the foot pedal valve is released, the cylinder extends and the dynamic pressure block and the static pressure block head cooperate to clamp the closing spring.
