The different fixtures required for use are installed through multiple mounting plates 33, so that the workpiece can be installed on each fixture for processing. When the workpiece needs to be processed, the mounting plate 33 corresponding to the workpiece installation position is rotated to the bottom of the cutter head. At this time, the limit ring 31 provided under a mounting plate 33 symmetrical to it can correspond to the extension plate 21 fixedly connected to one end of the fixing plate 2. When it is necessary to ensure that the workpiece corresponds vertically to the cutter head, the extension plate 33 can be used to The fixing rod 22 is fixedly connected to the bottom end of 21, and the connecting plate 23 slidably connected to the fixing rod 22 can slide up and down to adjust its height, so that the limiting rod 24 fixedly connected to the connecting plate 23 can be synchronously adjusted up and down, and the top of the limiting rod 24 passes through the extension plate 21, so that the top of the limiting rod 24 can pass through the extension plate 21 and be inserted into the limiting ring 31 to support and limit the position of the rotating ring 3, ensuring that the mounting plate 33 above the limiting ring 31 is symmetrical and vertically corresponds to the cutter head, and can prevent the mounting plate 33 from being tilted when the mounting plate 33 is aligned with the cutter head.

When replacing, the limit rod 24 can be lowered to separate it from the limit ring 31. By rotating the rotating ring 3, the mounting plate 33 corresponding to the tool head can be adjusted to quickly replace the tool head fixture, and ensure that the fixture corresponds to the upper and lower positions after clamping the workpiece to avoid deviation.

[0022] A support ring 241 is fixedly connected to the outer wall of the limit rod 24, a pressure ring 26 is slidably connected to the outer wall of the limit rod 24, and a pressure plate 261 is fixedly connected to the outer wall of the pressure ring 26; the support ring 241 is used to support the pressure ring 26, and when it is necessary to rotate the rotating ring 3, the pressure plate 261 is pressed down so that the pressure plate 261 applies pressure to the support ring 241, so that the limit rod 24 slides down and separates from the limit ring 31, so as to facilitate the rotation of the rotating ring 3.
