In addition, the bottom of the fixture block 45 is provided with a first conductive terminal 451, and the first conductive terminal 451 is electrically connected with the flat cable of the electronic paper inside the electronic paper display screen assembly 4; the second conductive terminal 15 is installed at the bottom of the slot 18, and the second conductive terminal 15 is electrically connected with the driving port of the display screen.
A first through groove for accommodating the second conductive terminal 15 is formed between the first mounting cavity 11 and the clamping groove 18; the second conductive terminal 15 is movably arranged in the first through groove; a second through groove communicated with the first mounting cavity 11 is formed at the bottom of the groove close to the inlet of the clamping groove 18; the top block 52 is movably arranged in the through groove, and the top of the top block 52 is obliquely arranged; a movable plate 51 is further arranged in the first mounting cavity 11, and the movable plate 51 is connected with the top block 52 and the second conductive terminal 15; a spring 53 is sleeved on the part of the top block 52 positioned in the first mounting cavity 11, the upper end of the spring 53 is fixedly connected with the inside of the first mounting cavity 11, and the other end of the spring 53 is fixedly connected with the movable plate 51; in a natural state, the upper ends of the top block 52 and the second conductive terminal 15 extend into the clamping groove 18; one side of the first mounting cavity 11 is provided with a through hole corresponding to the movable plate 51; one side of the movable plate 51 is provided with a movable rod 54 protruding out of the through-hole.
