[0032] Working principle: The switch base feeding assembly 3 sends the automotive switch base 80 to the station transmission assembly 2. The station transmission cylinder 10 acts to drive the push rod to push, so that the base push block 16 drives the switch base body 83 to move to the next station. At the station, the station limit assembly 13 makes the limit plug 29 limit the side of the switch base body 83 due to the elastic force of the buffer spring 30. The station transmission cylinder 10 returns to its original position. Due to the structure of the wedge portion 24 of the push block of the base push block 16, the wedge portion 24 of the push block swings downward, so that the base push block 16 returns to its initial position without affecting the position of the switch base body 83. Under the action of the transmission return spring 17, the wedge portion 24 of the push block swings upward again, driving the next automotive switch base 80 to move again.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
