transmitting and cooling water transmitting cropper pipe a 5 and the current transmitting and cooling water transmitting cropper pipe b 6 wherein the connection mode of the diffluent troughs 2 are determined by the actual demand of the fig1 30 and the main function of the diffluent troughs 2 is to lead the high frequency electric current 8 to be mutually used or crossed at the demarcation so that the raw material stick 16 is evenly heated up and the function of the subsidiary melting materials raw material stick 16 can be implemented after melting the part of the end head of the raw material stick 16 also called as raw material silicon stick which is near to the lower surface 10 of the high frequency coil the clamp head 14 of the seed crystal is lifted down along with the seed crystal 15 so that the seed crystal 15 passes through the pulling holes 3 referring to the fig1 30 and is inserted into a melting region of the raw material stick 16 the seed crystal 15 is lifted up the melted liquid at the upper part of the raw material stick 16 can be lifted up along with.
