This ancient case is the introduction of blood, poetry, as a flat plate,More detailed is that pey. Si, assembled horizontally, has established a direct cross serve flash on the flat. It is the non mechanical board and the serve. The connection between the non mechanical board and the non mechanical board is the main blood from now on. The service is on the BB machine board. Bippconer, which is carried out by the relay connection of receiving the ball and receiving the ball by the bikini tube. Because it is opened, the service skin has the disadvantage of flowTherefore, the present invention forms a coupling groove 22 on the upper side of the sub-PC. 16 substrate as shown in FIG. There is an effect that the flow of the sub-PC.substrate can be prevented by fixing the sub-PC.sub.substrate 16 with the fixed shaft 24.
