On centre bore, be equipped with second sleeve on the centre bore, the noumenal seat and noumenal seat lower cover are screwed togather by multiple screws.
Preferably, lid is equipped with multiple corresponding screw holes under the noumenal seat and noumenal seat.
Preferably, being equipped with axis clamp spring in the pinion shaft, Large Gear Shaft.
Preferably, the Large Gear Shaft is equipped with a keyway, flat key is equipped in the keyway.
Preferably, the central shaft hole of the large conical gear is equipped with a groove, the groove is adapted with flat key.
Preferably, the screw is hexagonal cylindrical head screw.
The utility model have it is compact-sized, can narrow space by change spanner active force direction, to for
Spanner works vacating space, and avoiding conventional method and needing to dismantle other parts just can tighten or the place of demounting bolt.Institute
Gear set is set inside the pedestal having and there is speed change and axis Perpendicular Transmission, and in band moving gear possessed by gear set
Jack-post one end is respectively equipped with by driving position and driving position at centre, and gear set is fixed on by conical bearing and axle sleeve in pedestal.This
Utility model tool is used in combination with box spanner, and offer driving force, driving position and set are connect with by driving position by sleeve tommy bar
Cylinder connection driving cap rotation is to dismounting or tightens bolt.
