In detail, the lower leg 41 and the upper leg 42 are disposed in an interlaced manner, and the upper leg 42 and the lower leg 41 do not overlap each other in the longitudinal direction of the adapter 1, and are perpendicular to the longitudinal direction of the adapter 1. There is also no overlapping area in the Y direction of the direction, but a gap difference, and the gap is set corresponding to the thickness of the spring rail 30, so that the spring rail 30 can be stably and properly engaged through the upper leg 42 and the lower leg 41.

Further, the outer shape of the spring rail 30 corresponds to the upper leg 42 and the lower leg 41 and their staggered arrangement, and a plurality of recesses 31 are provided. The recess 30 is sized to fit the upper leg 42 and the lower leg 41 individually, whereby the spring rail 30 can be firmly engaged between the upper leg 42 and the lower leg 41 to prevent the spring rail 30 from leaving the accommodating space 20. In detail, the root of the upper leg 42 can be engaged with the recess 31 provided in the spring rail 30 to be engaged in the recess 31, that is, the root of the upper leg 42 can be opposite the side of the recess 31 of the spring rail 30. Fit and abut, thereby blocking the possibility of displacement of the spring rail 30 in the longitudinal direction. Moreover, when the spring rail 30 is installed in the accommodating space 20, the upper leg 42 abuts against the upper side of the area around the bottom of the recess 31 of the spring rail 30, and the lower leg 41 abuts against the recess 31 of the spring rail 30. The lower side of the peripheral area of the side portion is thereby prevented from being separated from the accommodating space 20 by the direction in which the spring rail 30 is opened by the opening of the accommodating space 20. In this way, the lower leg 41 and the upper leg 42 can be stably fitted to the recess 31 of the spring rail 30 through the arrangement of the lower leg 41 and the upper leg 42 to prevent the spring rail 30 from leaving the accommodating space 20. Incidentally, the lower leg 41 has a notch 410 penetrating up and down, the upper leg 42 is located directly above the notch 410, and the shape of the upper leg 410 is not larger than the shape of the notch 410, and no movable core knot is required on the mold. The side portion can be manufactured by an injection molding process by means of upper and lower parting, and thereby, a gap between the lower leg 41 and the upper leg 42 can be formed to accommodate the spring member 30.

Further, in the first embodiment of the present invention, the limit portion 43 is more protruded between the side portions 10 between the two side portions 10. The limiting portion 43 can be embedded in one of the recesses 31 of the spring rail 30, and the two abutting surfaces 430 of the limiting portion 43 perpendicular to the protruding direction of the limiting portion 43 (ie, the longitudinal direction) can abut against the side of the recess 31 Further, the spring rail 30 is further blocked from moving in the longitudinal direction (as shown in FIGS. 4 to 7). The abutment surface 430 can cooperate with the side of the recess 31 of the spring rail 30 that has been mounted in the accommodating space 20, so that the spring rail 30 can be fixed in the longitudinal direction (ie, the X direction) of the adapter 1 (see 6 and 7), the spring rail 30 that has been installed in this way will be less likely to sway or detach in the longitudinal direction of the adapter 1. In other words, when the recess 31 of the spring rail 30 is engaged with the abutment surface 430 of the limiting portion 43 perpendicular to the longitudinal side, the through-the-hole 31 and the abutment surface 430 are mutually engaged in the longitudinal direction of the adapter 1. The spring rail 30 can be fixed in the accommodating space 20 (as shown in FIGS. 4 to 7).

In order to enable the reviewing committee to more clearly understand the present invention, the applicant has also proposed Figs. 4 to 7 in the first embodiment of the present invention.
