After loosening the connecting rod 11, the two arc plates 4 can be driven closer to each other under the elastic force of the spring 10, thereby clamping the manipulator, so that the protective shell 1 can be installed on the manipulator, and the fixing rod 3 can be fixed by the fixing assembly to ensure the stability of the overall device. During this process, the arc plate 4 can be driven to move by rotating the connecting rod 11, so as to facilitate the installation of the protective shell 1 on the manipulator, or to remove it from the manipulator, thereby facilitating subsequent maintenance work and improving the practicability of the device.
