As shown in fig. 4, 9 and 10, in the present embodiment, the first fixing hole 1013 has four corners, the first fixing plate 1014 is disposed at a lower left corner of the first fixing hole 1013, the lower left corner of the first fixing hole 1013 has a first edge 1013a and a second edge 1013b, the first edge 1013a substantially extends along the second direction X, the second edge 1013b substantially extends along the third direction Y, the third direction Y is perpendicular to the second direction X, and the first edge 1013a and the second edge 1013b extend toward and intersect with the lower left corner of the first fixing hole 1013 (as shown by the dotted line in fig. 10). The first edge 1013a is orthogonal to the first side 101c of the base plate 101, and the second edge 1013b is parallel to the first side 101c of the base plate 101. The first fixing plate 1014 has two first fixing bodies 1014a connected, each of the two first fixing bodies 1014a extending substantially upward along the first direction Z, and in this embodiment, one end of one of the two first fixing bodies 1014a is connected to the first edge 1013a and extends horizontally along the second direction X; one end of the other first fixing body 1014a is connected to the second edge 1013b and extends horizontally in a third direction Y perpendicular to the second direction X, so that the two first fixing bodies 1014a extend in different directions in the horizontal direction of the first surface 101 a. The two first fixing bodies 1014a of the present embodiment extend orthogonally to each other, and a junction between the two first fixing bodies 1014a has a chamfer or fillet 1014 b. The first fixing plate 1014 of the present embodiment is formed by punching the base plate 101 into the first fixing penetration hole 1013 and then bending the base plate out of the first fixing penetration hole 1013. Because the first fixing plate 1014 of the present embodiment has the chamfer or the fillet 1014b, the structural strength of the first fixing plate 1014 is increased, the first fixing plate 1014 is not easily deformed by an external force, and when the first connecting member 102 is disposed on the first fixing portion 1011, the first fixing plate 1014 is not easily deformed by an external force, and the first connecting member 102 is not easily separated from the first fixing hole 1013 or displaced on the first surface 101a of the base plate 101.

When the first connecting members 102 are disposed on the first fixing portions 1011, the first connecting members 102 fill the first recesses 1014d between each of the first fixing tabs 1014c and the first surface 101a of the base plate 101, and the first fixing tabs 1014c can be engaged with the first connecting members 102 filled in the first recesses 1014d, so that a portion of the first connecting members 102 abut against the edges of the first recesses 1014d, thereby increasing the contact area between the first connecting members 102 and the first fixing plates 1014. When the first connecting member 102 is pulled toward the key cap 13 by an external force, the first connecting member 102 is blocked by the two first fixing tabs 1014c and is not easily separated from the first fixing portion 1011.
