Further, the motor is additionally provided with mounting base, and the mounting base is fixedly connected with the cylinder.
Further, the mounting base both ends are bolted with the cylinder.The benefit being arranged in this way is connection type
It is stable and easy to disassemble.
The utility model has the advantages that the support column utilizes Pascal's law, charged piston is driven to move by setting motor.It is wherein electric
Machine can be using in the prior art arbitrarily with the motor of positive and negative rotating function, and when electric motor starting, output end is rotated forward, thereon outer
Screw-internal thread fit on screw thread and bearing, bearing moves on output shaft, to realize the elongation of column cap；It is defeated after use
Outlet reversion restores column cap.Meanwhile hydrostatic sensor is provided in sap cavity, which can be using any existing
Collected pressure information is transferred to signal transceiver in real time as long as realizing, passes through what is acquired in pressurization by technology
Numerical value and preset threshold compare, and support column is avoided to occur due to the excessive generation damage of pressure.The mode of battery is set simultaneously, it can
To allow support column in the case where no external power supply, work also can be carried out, increase application range.This programme is compared on the market
Support column, internal structure is simple, and more efficient utilizes support column inner space, while easy to disassemble when in use, when
Problem can be discovered and ruled out by dismounting in time when breaking down, there is practicability.
