Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

By setting the placement base 401, the meshing gear 402, the rotating base 403, the connecting pin 404, the clamping plate 405 and the sliding groove 406, during use, The clamping plate 405 is used to clamp the workpiece to be processed placed on the placement base 401. By moving the position of the clamping plate 405, the internal connecting column 404 will be driven to slide in the sliding groove 406. The sliding groove 406 is an arc-shaped moving trajectory that drives the rotating base 403 to rotate and drives the meshing gear 402 at the bottom to rotate. The meshing gears 402 engage with each other and drive the meshing gear 402 on the other side to rotate and turn in the opposite direction. In this way, the meshing gear 402 on the other side will drive the clamping plate 405 on the other side to move through the cooperation of the rotating base 403, the connecting column 404 and the sliding groove 406. In this way, each adjustment will ensure that the clamping plates 405 on both sides move at the same time, and when clamping the workpiece, it will ensure that the workpiece is always at the center of the placement base 401, thereby achieving the effect of preventing the workpiece from shifting.
[0023] Furthermore, there are two meshing gears 402 that mesh with each other, and there are two clamping plates 405 that are symmetrically distributed. The meshing gears 402 that mesh with each other will drive the meshing gear 402 on the other side to rotate in the opposite direction, driving the clamping plate 405 on the other side to move synchronously to achieve clamping.
[0024] Furthermore, the connecting pin 404 passes through the clamping plate 405, and the connecting pin 404 passes through the sliding groove 406. By moving the position of the clamping plate 405, the internal connecting pin 404 will be driven to slide in the sliding groove 406. The sliding groove 406 is an arc-shaped device that drives the rotating base 403 to rotate and drives the meshing gear 402 at the bottom to rotate.
[0025] Furthermore, the adjusting mechanism 5 includes a fixed shell 501, a threaded shaft 502, a movable clamp 503, a connecting protrusion 504, an adjusting knob 505 and a supporting frame 506.

By setting the fixed shell 501, the threaded shaft 502, the movable clamp 503, the connecting protrusion 504, the adjusting knob 505 and the supporting frame 506, During use, the threaded shaft 502 is supported by the fixed shell 501 and the support frame 506 respectively and can rotate. The threaded shaft 502 is driven to rotate by turning the adjusting knob 505. The outer surface of the threaded shaft 502 is threadedly connected with a movable clamp 503, and the movable clamp 503 is limited by the fixed shell 501 and cannot rotate to form a screw slide structure, and linear movement is achieved through rotation, and the movable clamp 503 is connected to the connecting protrusion 504 on the clamping plate 405. When the clamping plate 405 moves, it will drive the movable clamp 503 to move, and work together with the clamping mechanism 4 to clamp the workpiece, and the threaded connection has a self-locking effect. Only rotation can drive the clamping plate 405 to move, ensuring that the position of the clamping plate 405 will not change as long as the adjusting knob 505 is not rotated after clamping.
[0026] Furthermore, there are two fixed shells 501 and they are symmetrically distributed. The threaded shaft 502 penetrates the fixed shells 501 and is threadedly connected to the movable clamp 503. The symmetrically arranged fixed shells 501 simultaneously control both ends of the clamping plate 405 to disperse the force. The movable clamp 503 is limited by the fixed shell 501 and cannot rotate to form a screw slide structure, and linear movement is achieved through rotation.
[0027] Furthermore, the connecting protrusion 504 is fixedly connected to both ends of the clamping plate 405, the threaded shaft 502 is rotatably connected to the support frame 506, and the movable clamp 503 is connected to the connecting protrusion 504 on the clamping plate 405. When the clamping plate 405 moves, it will drive the movable clamp 503 to move.
[0028] Working principle: A CNC milling machine that prevents workpiece deviation. During use, the threaded shaft 502 is supported by the fixed housing 501 and the support frame 506 and can rotate. The threaded shaft 502 is driven to rotate by turning the adjusting knob 505. The outer surface of the threaded shaft 502 is threadedly connected with a movable clamp 503, and the movable clamp 503 is limited by the fixed housing 501 and cannot rotate to form a screw slide structure. The linear movement is achieved by rotation, and the movable clamp 503 is connected to the connecting protrusion 504 on the clamping plate 405. When the clamping plate 405 moves, it will drive the movable clamp 503 to move. The clamping plate 405 is used to clamp the clamp placed on the placement base 4 The workpiece to be processed on 01 will be driven to slide in the sliding groove 406 by moving the position of the clamping plate 405. The sliding groove 406 is arc-shaped, which drives the rotating base 403 to rotate and drives the meshing gear 402 at the bottom to rotate. The meshing gears 402 are engaged with each other, which will drive the meshing gear 402 on the other side to rotate and turn in the opposite direction. In this way, the meshing gear 402 on the other side will drive the clamping plate 405 on the other side to move through the cooperation of the rotating base 403, the connecting column 404 and the sliding groove 406. In this way, each adjustment will ensure that the clamping plates 405 on both sides move at the same time, thus completing a CNC milling machine that prevents workpiece deviation.
