Abstract
The utility model relates to an electric jack which comprises a main jack. The utility model is characterized in that a main jack is fixedly installed on a base plate of a hand cart; a motor and a speed reducer which is driven by the motor are fixed on the base plate; an output shaft of the speed reducer is connected with the end of a connecting rod, and a rotary shaft is arranged at the other end of the connecting rod; a sliding sleeve is arranged at the end of the rotary shaft, and is sheathed on a pressing rod of the main jack. Through the connecting rod and the sliding sleeve, the output shaft of the speed reducer of the utility model drives the pressing rod of the main jack to swing upwards and downwards so that the jack works. The problem of difficult manual operation of maintenance of a multi-bridge large-tonnage truck is solved and much manpower is saved, and the utility model has the advantages of a large hoisting tonnage, high speed and good safety performance. In addition, the hand cart of the utility model is provided with a lifting device for the base plate, so that the base plate can be lifted optionally according to the application condition, and with more operation, the utility model is more convenient for maintenance of the multi-bridge truck.
Description
Technical field
The utility model relates to a kind of power tool, is a kind of electronic jack specifically.
Background technology
