The axial sections of the common rotating shaft 9 and the standby rotating shaft 10 are hexagonal, and the hexagonal structures are stressed uniformly in the process of transmitting torque relative to the torque transmission structure of the key slot.

The working process of the utility model is as follows:

as shown in fig. 1, in the initial position, the normal power module 2 is in the open state, and the right standby power module 3 is in the open state. The corresponding interlock mechanism 410 is shown in fig. 8 with the conventional interlock tab in a horizontal position and the backup interlock tab in a vertical position. The conventional interlock projection engages with the conventional interlock recess 41013. When the common motor 402 drives the common gear set 411 to rotate, the common gear set 411 drives the left interlocking shaft to rotate through the common transmission gear 4111, the common coupler 4104 rotates 90 degrees anticlockwise, the common coupler 4104 is fixedly connected with the common rotating shaft 9, the common power module handle 21 rotates 90 degrees anticlockwise, and therefore the common power module 2 is switched on. As shown in fig. 9, the normal interlock 4102 is rotated together, the normal interlock projection slides out from the normal interlock recess 41013 along the normal interlock recess inclined surface 41011, and since the normal interlock 4102 can only be rotated and cannot slide in the normal interlock positioning hole 4011 and the interlock block 4101 can only be slid and cannot rotate in the stopper 4013, the normal interlock 4102 moves the interlock block 4101 to the right and the backup interlock recess 41014 is fitted to the backup interlock projection. At this time, the normal interlock projection end surface 41022 contacts against the normal interlock end surface 41015, so that the movement of the interlock block 4101 leftward along the interlock block guide groove 4014 can be restricted, and therefore, the right interlock shaft cannot be rotated, and the backup interlock 4103 is prevented from rotating to tend to close the backup power supply module 3, thereby playing a role of interlocking.

Similarly, as shown in fig. 1, in the initial position, when the backup motor 403 drives the backup gear set 412 to rotate, the backup gear set 412 drives the right interlocking shaft to rotate clockwise by 90 ° through the backup transmission gear 4121, the backup coupling 4105 is fixedly connected to the backup rotating shaft 10, and the backup power module handle 31 is also rotated clockwise by 90 °, so that the backup power module 3 performs a closing operation. As shown in fig. 10, backup interlock 4103 is simultaneously rotated together, backup interlock projection slides out from backup interlock recess 41014 along backup interlock recess inclined surface 41012, backup interlock 4103 can only be rotated and cannot slide in backup interlock positioning hole 4012, and interlock block 4101 can only be slid and cannot rotate in stopper 4013, so backup interlock 4103 moves interlock block 4101 to the right, and normal interlock recess 41013 coincides with normal interlock projection. At this time, the backup interlock projection end surface 41032 contacts against the backup interlock end surface 41016, so that the right movement of the interlock block 4101 along the interlock block guide groove 4014 can be restricted, and therefore, the left interlock shaft cannot rotate, and the tendency that the normal interlock part 4102 rotates to close the normal power supply module 2 is prevented, thereby playing an interlock role.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
