Property；When 2 stop motion of backboard is located in a certain position, gas bar 4 also functions to the Auxiliary support effect to backboard 2, gas bar auxiliary
Electric pushrod increases self-lock force, reinforces the load capacity of backboard.
The present apparatus is by each side increasing a gas bar in electric pushrod, so that having when rising backboard makes electricity
Machine can reduce load and be operated.Electric putter is caused to slow down backboard because gas bar can assist electric putter to prop up backboard
Pressure, make electric putter load reduction, thus allow electric putter operation it is more smooth, the service life of electric putter can also be extended.Back
When plate declines, gas bar avoids backboard to the supporting role of backboard and declines too fast, the stationarity of reinforcement decline process.Backboard stops
When movement, gas bar auxiliary electric push rod increases self-lock force, reinforces the load capacity of backboard.
The embodiments of the present invention is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Above embodiment can also not depart from the utility model within the knowledge of a person skilled in the art
Objective under the premise of make a variety of changes.
