[0026] Furthermore, the card rod 5 is cylindrical in shape, and the telescopic grooves 6 are provided in two groups on both sides of the card rod 5, and the abutment plate 7 is correspondingly connected to the telescopic grooves 6. Through the connection between the card rod 5 and the card block 4, under the action of the card rod 5, the card support effect between the support main frame 1 and the card block 4 is realized.
