Further, the worm screw mounting point of said cabinet exterior is cone table shape, directly contracts from worm screw tail end forward end direction.
Further, said casing is the removable adpting flange that is connected with at power input hole place, and adpting flange has the boss that stretches into casing power input hole.
Further, said adpting flange is connected with casing removable through two bolts that circumferentially are uniformly distributed with at least.
Further, the said adpting flange outside has installation base, is set with rubber pad on the installation base, and the rubber pad end face is concordant with adpting flange end face and outer rim respectively with outer rim.
Further, said worm gear and worm screw respectively are sleeved in the casing through pair of bearings is rotatable.
Further, said worm gear and worm screw are equipped with positioning step in the Bearing Installation position.
Further, said bearing is located through jump ring at the opposite side relative with positioning step.
Further, said bearing is a deep groove ball bearing.
Further, said liquid sealing device is an oil sealing.
The beneficial effect of the utility model is: housing structure is reasonable, and structure is light and handy and firm; Power input hole and power delivery outlet only are set and the reliable sealing seal arrangement is set, the liquid good leak tightness effectively prevents leakage of oil; Cabinet wall and worm gear, worm screw gap are little, and volume read-out is few; The linkage structure of worm gear and worm screw and casing is simple and reliable, and not only safety action was smooth and easy but also can prevent to rock the complete machine long service life.
