The end of the extension rod 252 away from the raised shaft 251 is fixedly connected with a counterweight ball 253. The raised shaft 251 is manually driven to rotate, which drives the screw rod 25 to rotate, so that the sliding seat 26 drives the access card sensing device body 1 to rise and fall, which is convenient for users of different heights to swipe the card. Through the design of the extension rod 252 and the counterweight ball 253, the user can make the raised shaft 251 rotate continuously for a period of time with a single force, reducing the cumbersomeness of rotating the raised shaft 251.
