rotation comes from the influence of the propping and resetting of the first spring 18, the clockwork spring 39 contracts again, the contraction is slight, the metal column 11 is not influenced to be completely inserted into the surge protector 7, and the axial movement and the dislocation between the shaft gear 33 and the shaft gear 33 can be realized all the time.
When thunder hits the box body 1, the work of the surge protector 7 finishes the transfer of the thunder, in-process static electricity affects the solenoid 30, the solenoid 30 generates magnetic force, deformation and contraction of the spring 39 are caused through transmission, after the thunder passes, the spring 39 resets, and then the wiring pieces 6 on two sides deform, the metal columns 11 of the inserted surge protector 7 are all pulled out from the surge protector 7, in this way, the pressing pieces 5 are elastically pressed, the new surge protector 7 is pushed to the power connection position, the metal columns 11 on two sides are far away from the surge protector 7 and then reset and inserted onto the new metal column 11 again, the wiring pieces 6 reset in time are carried out before the new surge protector 7 moves to the power connection position, namely, the metal columns 11 on two sides reset and are abutted onto the shell of the new surge protector 7, the surge protector 7 continuously slides the metal columns 11 to meet wiring column grooves on the shell of the surge protector 7 and then insert along with the potential, and thus the inserting work is stably finished.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
