Referring to fig. 3 and 4, in the present embodiment, the fixing block 12 includes a fixing portion 121 connected to the seat body 11, and a mounting portion 122 connected to the fixing portion 121, and the wire passage 1221 penetrates two opposite side surfaces of the mounting portion 122; the wire pressing base 22 has two opposite clamping plates 221, and the two clamping plates 221 are clamped on the other two opposite sides of the mounting portion 122 and are rotatably connected with the mounting portion 122, so that the wire pressing handle 20 can rotate around the mounting portion 122. For convenience of description, the wire passage 1221 penetrates through the two opposite side surfaces of the mounting portion 122, where the side surface on the wire outlet side is a first side surface, and the side surface on the wire inlet side is a second side surface. The other two opposite side surfaces of the mounting portion 122 are a third side surface and a fourth side surface, respectively.

Thus, when the wire 70 is bent for the second time, the limiting surface can limit the bent first section to deviate towards the direction away from the fixing part 121, and the deviation error between the first section and the second section can be reduced. Of course, in other embodiments, two limit plates 50 may be mounted on the mounting portion 122, the wire 70 may be located between the two limit plates 50, and so on.
