Is rotated, the support member 1C remains at that position, but the support members 1R and 1L move toward and away from the support member 1C. In this case, in order to move the nozzle members 8R, 8L and the nozzle member 8C forward and backward while maintaining the same distance, the initial distance between the support members 1R, 1C, 1L is made equal, and the pitch between the right-hand thread 27 and the left-hand thread 28 is adjusted. Need to be equal. The knob 25 is manually operated.
Instead of rotating the shaft, it is also considered to rotate the shaft 22 using mechanical or electrical means.

An output shaft 31 of a motor or motor 30 fixed to the center of the bottom of the frame 18 has three sprocket wheels 32, 33 and 34 fixed thereto and two first arms 35 and 36 connected thereto. It is loosely fitted. The sprocket wheel 32 transmits rotation through a chain 37 to a sprocket wheel 38 fixed to the shaft 2C of the support member 1C. These sprocket wheels 3
7, a chain 37 and a sprocket wheel 38 constitute a transmission means 39.

The transmission means 40 and 41 for the support members 1R and 1L are symmetrical with respect to the output shaft 31. First, the right transmission means 40 will be described. A first transmission member 40a for driving a sprocket wheel 44 fixed to an intermediate shaft 43 rotatably supported by the first arm 35 is formed, and a sprocket wheel 45 coaxial with the sprocket wheel 44 is connected to the intermediate shaft. A second transmission member 40b for rotating and driving a sprocket wheel 48 fixed to the shaft 2R via a chain 47 extending along a second arm 46 provided between the shaft 43 and the shaft 2R of the support member 1R.
