[0025] The squeezing and fixing mechanism 6 includes a push plate 601 , a clamping plate 602 and a spring 603 . Two groups of push plates 601 and clamping plates 602 are symmetrically arranged at the upper and lower ends of the sub-line terminal 3 . A plurality of springs 603 are fixedly connected between each group of push plates 601 and clamping plates 602 .

[0026] See also Figure 4 The extrusion and fixing mechanism 6 also includes a protective pad 604 and a fixing block 605. The protective pad 604 is fixedly installed on one end of the two clamping plates 602 close to the sub-line terminal 3, and the fixing block 605 is fixedly installed on one end of the two push plates 601 away from the sub-line terminal 3.

[0027] In this embodiment, when the push plate 601 pushes the clamping plate 602 to move close to one end of the sub-line terminal 3, the protective pad 604 is pressed on the sub-line terminal 3 to play a protective and fixed role. The push of the push plate 601 is controlled by the fixed block 605.
