Specific implementation content

A main support tube is made of light material such as plastic or aluminum alloy. There are four protruding blocks connected to the support rod at both ends of the main support tube, and the four protruding blocks at one end are connected with the four protruding blocks at the other end. The blocks are 45 degrees to each other, one upper movable bracket, and one end of the upper movable bracket also has four raised blocks, one lower movable bracket, and one end of the lower movable bracket also has four raised blocks, four upper support rods, four lower Support rods, 16 connecting pieces, two fixed knobs, 22 pin shafts, a cover, and a seat cushion. The seat cushion is made of the same material as above into several rod shapes, and is connected with the holes on the rod with four flexible wires. The round rods at the ends each have four plugs connected and fixed to the four upper support rods. Both the upper support frame and the lower support frame are pipe bodies inserted into the two ends of the main support tube respectively and can move coaxially with the main support tube. The four upper support The support rod and the four lower support rods are respectively folded and placed around the two ends of the main support tube, and the connecting pieces are respectively connected with the upper and lower support rods and the upper and lower movable brackets with pin shafts. The upper and lower knobs In the state of opening and loosening, the seat cushion roll is placed in the space of the upper movable bracket, the main support tube, and the lower movable bracket, and the cover is sealed. When in use, open the cover, take out the seat cushion, and rotate the upper support rod upwards to connect with the connecting piece. Keep it fixed, tighten the No. 1 fixing knob, rotate the lower support rod downward until it is fixed with the connecting piece, tighten the No. 2 fixing knob, and connect the four plugs on the cushion with the four upper supports The connecting hole of the rod is positioned and inserted and fixed, and it can be used. Due to the integrated design of folding and zooming and lightweight materials, it is light in weight, easy to carry, safe and firm to use.
