A mounting block 16 is fixedly arranged at the bottom end of one side of the first bracket 2. A fixing groove 17 is opened at the end of the mounting block 16 away from the first bracket 2. A placement frame 18 is arranged at the end of the mounting block 16 away from the first bracket 2. A fixing plate 19 is fixedly arranged at one end of the placement frame 18 close to the mounting block 16. One end of the fixing plate 19 is movably arranged inside the fixing groove 17. A limiting groove 20 is opened above the fixing groove 17 on one side of the mounting block 16. A limiting plate 21 is fixedly arranged on one side of the placement frame 18. One end of the limiting plate 21 is movably arranged inside the limiting groove 20. A square groove 22 is opened at the top of the mounting block 16. A pull rod 23 is arranged inside the square groove 22. The pull rod 23 passes through the limiting plate 21 and the fixing plate 19 respectively through movable holes.
[0024] In this embodiment, preferably, a turning handle 24 is installed at one end of the limiting rod 8 away from the first bracket 2 to facilitate the rotation of the limiting rod 8 .
[0025] In this embodiment, preferably, the end of the card block 10 close to the card slot 9 is arranged in a trapezoidal shape to prevent the card block 10 from falling.
[0026] In this embodiment, preferably, both upper and lower sides of the limit block 14 close to one end of the slider 11 are elastically arc-shaped, so as to facilitate fixing the slider 11 .
