The application relates to a puncture surgical robot and a sterile cover for an interventional puncture surgical mechanical arm. The sterile cover comprises a protective sleeve, at least one profiling piece and a first fixing structure. The protective sleeve is used for sleeving an execution end; the at least one profiling piece comprises a moving profiling piece, the moving profiling piece has an opening, the profiling piece is communicated with the protective sleeve through the opening, and the profiling piece is used for adapting to the shape of an execution mechanism of the execution end to be sleeved outside the execution mechanism; and the moving profiling piece is fixedly connected with the execution mechanism through a second fixing structure, so that the cross-sectional dimension of the sterile cover in a first direction can be effectively reduced, that is, the redundancy of the sterile cover is reduced, and the risk of infection caused by the puncture needle puncturing the sterile cover is avoided.

The application discloses a tower type heliostat support and relates to the technical field of solar energy utilization. The tower type heliostat support comprises a mirror surface supporting assembly, an elevation angle transmission assembly and a direction angle transmission assembly. The mirror surface supporting assembly comprises a mirror surface supporting plate and a support structure. The mirror surface supporting plate is fixed on the support structure. The elevation angle transmission assembly comprises an elevation angle hinged bearing, a transmission track and an elevation angle driving bearing. The elevation angle hinged bearing is fixed on the mirror surface supporting plate. The transmission track is connected between the elevation angle hinged bearing and the elevation angle driving bearing. One end of the elevation angle driving bearing is connected with the support structure, and the other end of the elevation angle driving bearing is connected with the direction angle transmission assembly. The application increases the integrity between the sub-mirrors, promotes the reflection of the sub-mirrors, avoids light dispersion, and changes the elevation angle through the movement of the transmission track driven by the elevation angle driving bearing, so that the application is suitable for various mirror field arrangements. The transmission mode is simple and direct, and the transmission track can be replaced.
