This reality has the novel following advantage that has compared to existing technology:

1, by the flanged oil-impregnated bearing of employing, accurate positioning, assembly technology is simplified, and reduces the oil-impregnated bearing distortion, has improved the stability of transmission shaft running greatly.

2, the transmission shaft after the improvement takes the mode of circular shaft annular knurl or floating screed to substitute former flat key Placement, and guide-localization is good, does not promptly influence the transmission of moment, can simplify axle head screens structure again, has greatly improved the runnability of assembling with axle.

3, cylinder adopts aluminum alloy, engineering plastics combined tessera, and fuse with cylinder end piece, can reduce cost of material, can simplify air cylinder head structure again, need not to be tightly connected, can improve the stability of air pressure, inner tube wall adopts anodization can prolong cylinder working life, and reduce cost, improve installation precision.

4, consider that this machine is everlasting outdoor and night, rain, greasy weather gas use, traditional illumination lamp is improved, realized illumination, caution, SOS emergency integrated multi-functional light fixture, and, realized long lifetime, low power consumption by adopting novel rotational wave switch and control wiring.

5, the electron pressure table pre-sets force value at 0.2～0.6Mpa, when starting shooting, automatically by the setting value shutdown, has shortened the time that pressure is provided with at every turn.Prevent that inflation pressure is excessive, cause inflatable substrate to destroy.

6, tire pressure test control accuracy height, this just means: the fuel consumption of vehicle driving is lower, tire longer service life, braking effect and to control performance better.
