a glue pouring groove 24 communicated with the lower accommodating groove 23 is formed between the lower outer enclosing wall 21 and the upper outer enclosing wall 11;

the lower cover 2 is provided with a fixed seat 4; the upper cover 1 is provided with a fixed table 5 matched with the fixed seat 4; the fixing seat 4 is provided with a glue filling cavity 41; two ends of the glue filling cavity 41 are respectively communicated with the bottom of the glue filling groove 24; the fixing table 5 is provided with connecting ribs connected with the upper cover 1 at corresponding positions of the glue filling cavity 41; the top of the connecting rib is communicated with the glue filling groove 24; the bottom of the connecting rib is communicated with the glue filling cavity 41;
