The lower end of the connecting stud 6 is fixed at the top of the spherical surface, the upper end is suspended in the air, and the suspended end is provided with threads. The opening end of the seat shell 2 end is a corresponding surface of a spherical surface. The inner wall of the opening end of the seat shell 2 is provided with threads.

The connecting stud 6 is in threaded connection with the connector 1. The connector 1 is a cavity structure of a truncated cone. The lower end of the connector 1 is a circular truncated cone large-diameter end face, and the upper end of the connector is a circular truncated cone small-diameter end face. The upper part of the cavity of the connector 1 is a circular truncated cone cavity, and the lower part of the cavity is a cylindrical cavity. The upper end of the round cavity is a small-diameter circle. The inner wall of the cylindrical cavity of the connector 1 is provided with threads. The thread of the connecting stud 6 is engaged with the thread of the inner wall of the cylindrical cavity at the lower end of the connector 1. The connector 1 is located at the apex of the sphere. The upper end face of the connector 1 is provided with a connecting hole 11. The attachment holes 11 are threaded holes. The connection hole 11 penetrates the upper end surface of the connector 1.

The opening end of the seat shell 2 is connected with a columnar seat body 3 made of soft rubber and plastic in a threaded mode. The seat body 3 is made of soft rubber plastic bar. The base body 3 is a structure with the upper part being a cylinder and the lower part being a round table body, and the cylinder and the large-diameter end of the round table body are smoothly connected. The outer surface of the cylinder of the seat body 3 is provided with threads. The cylindrical thread of the seat body 3 is meshed with the thread on the inner wall of the opening end of the seat shell 2. The seat body 3 is provided with a step-shaped hole. The large diameter hole of the step-shaped hole is a screw hole 31, and the small diameter hole is a through hole 32. The screw hole 31 is a conical hole. The large diameter end of the screw hole 31 is positioned on the small diameter round end surface of the round table body of the seat body 3. The small-diameter end of the screw hole 31 communicates with the through hole 32 and forms a step with the through hole 32. The cross section of the seat body 3 is wedge-shaped on the side wall of the screw hole 31. The seat body 3 is cut along the central axis, and the side wall of the screw hole 31 and the side wall of the seat body 3 are wedge-shaped. The wedge-shaped point is positioned on the small-diameter round end surface of the round platform body of the seat body 3.

The end face of the through hole 32 is connected with a power supply control cabin 5. The power control cabin 5 comprises a battery cabin 51 and a control panel cabin 52. The battery compartment 51 has a rectangular frame structure, and a structure for mounting four cylindrical batteries is shown for illustration.
