The quick clamping device is suitable for 3D instruments

The utility model relates to a quick clamping device suitable for a 3D instrument, which comprises a moving seat, the moving seat is connected with a moving block through a connection positioning assembly, an elastic assembly is arranged between the moving block and the moving seat, and a holding assembly is arranged on the moving block. Therefore, the moving seat is matched with the moving block,so that the top structure of the 3D instrument can be stably clamped and positioned, and the stability after installation is ensured. Limiting adjustment is achieved through the elastic assembly, effective limiting can be achieved according to the top appearance contours of different 3D instruments, and the stability of final installation is guaranteed. And an independent holding assembly is arranged, so that stable adjustment of a user in the assembling period is facilitated. The whole structure is simple and easy to manufacture and assemble. 本实用新型涉及一种适用于3D仪器的快速夹紧装置，包括有移动座，移动座通过衔接定位组件连接有移动块，移动块与移动座之间设置有弹性组件，移动块上设置有握
