On the one hand, after the driving force on the operating handle 203 is withdrawn, the tool clamping assembly 202 can return to its original position, thereby facilitating the alignment operation of the master-slave manipulator and the operating handle 203 during the next processing; on the other hand, when the operating handle 203 is driven, the elastic member 204 can provide a reaction force, thereby providing an operating touch to the staff or the master-slave manipulator control system, thereby facilitating the position adjustment of the tool clamping assembly 202.

[0058] In some optional embodiments, the operating handle 203 includes a first operating rod 2031 and a second operating rod 2032; one end of the first operating rod 2031 is rotatably connected to the guide column 201; one end of the second operating rod 2032 is rotatably connected to the other end of the first operating rod 2031, and the middle part of the second operating rod 2032 is rotatably connected to the tool clamping assembly 202. Specifically, the middle part of the second operating rod 2032 is rotatably connected to the first sleeve ring 2021.

[0059] In the multifunctional processing stand for small radioactive elements provided in the embodiment of the present application, the first operating rod 2031 and the second operating rod 2032 constitute a labor-saving connecting rod, which can reduce the driving force requirement for driving the operating handle 203 and improve the operating convenience.

[0060] In some optional embodiments, a rotation limiting assembly 2033 is further configured between one end of the first operating rod 2031 and the guide column 201 to limit the rotation of the first operating rod 2031; in actual implementation, the rotation limiting assembly 2033 can be set as a tightening bolt, and a cross stiffening rod 309 is set at the end of the tightening bolt to facilitate the staff to operate the tightening bolt using the master-slave manipulator.

[0061] The embodiment of the present application provides a multifunctional processing stand for small radioactive elements. The setting of the rotation limit assembly 2033 can maintain the state of the operating handle 203, thereby maintaining the position of the tool clamping assembly 202, which is convenient for sample processing.
