Abstract

A strongly fixed tennis wall, comprising a wall and supporting and fixing columns connected to both sides thereof, the roller curtain device on the top of the wall is connected to a driving motor, and the driving motor is connected to a power supply through a temperature controller. The front and rear sides of the fixed column are respectively hinged with the bottoms of the front and rear rotating support shafts, and the No. 1 fixed bolt passes through the first fixed hole, the front side of the supported fixed column, the rear side of the supported fixed column, and the rear fixed hole. Carry out threaded connection with the No. 1 fixing nut afterward, and the inside of supporting fixed column can offer hollow cavity to put forward slanting column, rear slanting column on hold. This design not only has strong fixing strength, but also is easy to carry and install.
