[0038] In the character insert structure of the embodiment, referring to Figure 5 or Figure 6 , the fixing structure comprises a fastener 31 and a through hole 32 provided on the character block, the through hole 32 is used for the fastener 31 to pass through, a threaded hole 33 is provided in the mounting component, and the fastener 31 is connected with the threaded hole 33 after passing through the through hole 32. Through the above setting, the fastener 31 is threadedly connected with the mounting component after passing through the through hole 32, so that the fixing and quick disassembly of the character block are realized.
[0039] In the character insert structure of the embodiment, referring to Figure 5 , the through hole 32 comprises a first through hole 321 and a second through hole 322, and the character block comprises: a first character surface 1111 and a third character surface 1113 oppositely arranged with the first character surface 1111, and the first through hole 321 is provided between the first character surface 1111 and the third character surface 1113; a second character surface 1112 and a fourth character surface 1114 oppositely arranged with the second character surface 1112, and the second through hole 322 is provided between the second character surface 1112 and the fourth character surface 1114; wherein the extension direction of the first through hole 321 is perpendicular to the extension direction of the second through hole 322.
