[0006] Preferably, the upper and lower inclined grooves are distributed on both sides of the fixed groove, and both the upper and lower inclined grooves are connected to the fixed groove.

[0007] Preferably, there are two stakes and two positioning angles, and the two stakes are symmetrical about the two ends of the stake body.

[0008] Preferably, an inner groove is provided between the two pins, and inclined inner walls are provided on both sides of the inner groove.

[0009] Preferably, each of the two positioning angles is provided with a bevel at one end, and the two beveled inner walls are engaged in the lower edge groove; the bevel is used to cooperate with the upper edge groove and the lower edge groove, and the two beveled inner walls are used to hold the upper cover suction cup as a whole and fix it above the patch.

[0010] Compared with the prior art, the utility model discloses the fixed mode of patch and upper lid suction disc is changed from glue pouring fixed to buckle type fixed, not only reduce the cost, and be favorable to the promotion assembly efficiency, in addition, through buckle type fixed can also avoid the phenomenon of upper lid suction disc skewing caused by glue expansion, thereby improved the yield.
