[0014] The utility model provides a three-dimensional imaging scanner with an anti-shake device, which has the following beneficial effects:
[0015] (1) The 3D imaging scanner with anti-shake device can easily drive the turntable to rotate by operating the handle on the turntable, thereby prompting the active gear to drive the driven gear, so that the bidirectional screw rod can rotate flexibly. This process causes the placement plate and the counterweight plate to move relative to each other, the placement plate rises and the counterweight plate falls, effectively lowering the center of gravity of the device, effectively preventing the shake caused by slight sliding of the ground, and significantly improving the stability of the device.
[0016] (2) When the angle of the three-dimensional imaging scanner with an anti-shake device needs to be fixed, it is only necessary to rotate the adjustment block to bring it closer to the pressure block. This action will compress the reset spring, thereby increasing the pressure of the spring on the pressure block, so that the bottom of the pressure block fits tightly with the top of the support seat. Due to the tight pressure of the pressure block, the rotating disk will not be able to rotate, thereby ensuring that the angle of the scanner is stably fixed. When the angle of the scanner needs to be readjusted, it is only necessary to rotate the adjustment block in the opposite direction to move the pressure block away from the support seat, and the angle can be easily adjusted. The operation is both convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS
