[0029] The external seat 31 is provided with two first transverse holes 51 respectively located on the left and right sides of the internal insertion cavity 32; the two internal limit assemblies each include a transverse main shaft 52 slidably arranged in the first transverse hole 51, and the inner side of the transverse main shaft 52 has an inclined first inclined surface 521, and the first inclined surface 521 will cause the transverse main shaft 52 to move outward when it contacts the external circuit board 33; the external seat 31 is provided with a second transverse hole 61 located at the upper end of the first transverse hole 51, and the upper end of the transverse main shaft 52 is fixedly provided with a connecting block 62 located in the second transverse hole 61;
