[0036] After the borosilicate pharmaceutical glass tube is fixed, the locking knob 5 on the surface of the second hollow rod 8 is loosened, so that the adjusting cross rod 9 can slide and rotate in the inside of the second hollow rod 8, and the position of the borosilicate pharmaceutical glass tube can be adjusted, which is convenient for subsequent position adjustment of the borosilicate pharmaceutical glass tube, and the angle of the borosilicate pharmaceutical glass tube can be adjusted when the first fixed half ring 10 is rotated, and the first fixed half ring 10 is limited after the borosilicate pharmaceutical glass tube is adjusted.

[0037] When the borosilicate pharmaceutical glass tube clamped and fixed by the first fixed half ring 10 and the second fixed half ring 13 needs to be rotated, the adjusting button 17 on the adjusting block 16 is pressed, one end of the adjusting button 17 enters the inside of the adjusting inclined groove 20 to extrude the inclined surface of the adjusting inclined groove 20, the plug-in block 19 slides into the inside of the adjusting block 16 under the extrusion of the adjusting button 17, and the second spring 18 is extruded to deform and shrink when the plug-in block 19 slides into the inside of the adjusting block 16, and one end of the plug-in block 19 is separated from the inside of the adjusting groove 15 when the plug-in block 19 enters the inside of the adjusting block 16, so that the rotating shell 6 on the surface of the support shaft 7 can be rotated, and the borosilicate pharmaceutical glass tube clamped and fixed by the first fixed half ring 10 and the second fixed half ring 13 can also be rotated when the rotating shell 6 can be rotated.
