On both side surfaces of the symmetric U-shaped grooves of the middle upper beam and the middle lower beam, a sealing felt is respectively provided. Wool is filled between the two sealing felts. On the two side beam surfaces in the upper frame area and the lower frame area, several limiting short tubes are respectively symmetrically spaced and fixed. Four ribs are fixed on the frame surface in the lower frame area. The bushing is fixed in the bushing hole in the middle of the upper beam of the frame. The lower end of the valve plate passes through the channel port, two valve plate ports and the wool between the two valve plate ports and is inserted into the channel. A pull block is fixed on the upper end surface of the valve plate outside the channel port. One end of the lead screw is screwed with the screw hole of the pull block, and the other end of the lead screw passes through the bushing and is fixed with the wheel. An L-shaped guard plate is respectively fixed on the outer surface of the upper beam on both sides of the wheel.
