[0021] The following will further explain the specific implementation manner of the present utility model in conjunction with the attached Figures 1 - 10 drawings.

[0022] The fixed scroll side hole drilling device includes a turntable 1. The base plate 2 is a stepped cylinder structure. The base plate 2 is installed on the turntable 1 through the outer circle 13 in the middle. There are four hexagon socket head cap screws 1. The hexagon socket head cap screws 1 pass through the step hole 10 and are threadedly connected with the turntable 1. The positioning plate 4 is a stepped cylinder structure. The positioning plate 4 is inserted into the inner hole 12 of the base plate 2 through the outer circle 2 in the middle. There are four hexagon socket head cap screws 2. The hexagon socket head cap screws 2 pass through the step hole 18 of the positioning plate 4 and are fastened to the threaded hole 11 of the base plate 2. A positioning pin 9 is installed on the base plate 2. The positioning pin 9 is installed in the inner hole 15 of the base plate 2 through the outer circle 3. Studs 7 are installed on both sides of the base plate 2. The external thread 22 of the studs 7 passes through the threaded hole 2 of the base plate 2 and the inner hole 3 of the pressure plate 6 and is threadedly connected with the nut 8.
