As shown in fig. 5 and 6, the clamping support portion 12 may include: a first through hole 121 having a thread, two elastic wings 122 disposed at edges of the through hole and opposite to and spaced apart from each other in a first direction ((D1 direction shown in fig. 6)), and a support bracket 123 supporting the two elastic wings, wherein a passage through which the fastening member 11 passes to be fastened to the first through hole 121 is formed between the two elastic wings 122. The two resilient tabs 122 may move toward and away from each other in a first direction (direction D1 shown in fig. 6) and the tops abut against the inside surfaces of the lips extending from the opening of the recess 22 of the metal roof 20. In the case that the clamping support 12 is placed in the groove 22 of the metal roof 20, firstly, as shown in fig. 1 and 3, the extending and contracting directions (D1 direction shown in fig. 6) of the two elastic fins 122 are parallel to the extending direction of the groove (correspondingly, the cross-sectional view of the clamping support 12 is D2 direction shown in fig. 6), after the fixing part 13 is connected to the clamping support 12 through the fastening part 11, the clamping support 12 is driven to horizontally rotate by 90 ° by rotating the fastening part 11 to obtain the structure shown in fig. 2 or fig. 4, so that the extending and contracting directions (D1 direction shown in fig. 6) of the two elastic fins 122 are perpendicular to the extending direction of the groove, and as the fastening part is fastened, the fins are blocked by the lip of the groove, and the fins are further opened, the contact area of the fins and the lip is further increased, so as to better leave the clamping support 12 in the groove of the metal roof; the first through hole 121 is screwed with one end of the fastener 11; the support bracket 123 is fixedly connected to the first through hole 121 and the two elastic wings 122. The two elastic fins 122 are fixedly connected with the support frame 123, so that the two elastic fins 122 can not be stretched freely, and the elastic fins 122 can be expanded or contracted only by means of external force, so that the elastic fins 122 have elasticity and rigidity, and the elastic fins 122 can be contracted only by large external force, thereby effectively avoiding the occurrence of the situation that the clamping support part 12 slides out of the groove 22 due to the contraction of the elastic fins 122.

So that the clamping support part 12 can be better left in the groove 22, thereby better fixing the photovoltaic module on the metal roof 20 and avoiding the situation that the clamping support part 12 falls off due to long-term use.

It is worth noting that as the fastener is tightened, the two elastic wings 122 are further separated from each other and opened due to the compression of the lips, and the further separation of the two elastic wings 122 is opened, so that the supporting force between the lips extending out of the groove 22 is larger, and the fixed support structure 10 and the photovoltaic module can be more stably fixed on the metal roof 20.

Further, as shown in fig. 5 and 6, the supporting frame 123 may include: a first support plate 1231 disposed around an edge of the first through hole 121 and two second support plates 1232 disposed obliquely upward from two opposite sides of the first support plate 1231 in a second direction (D2 direction shown in fig. 6) perpendicular to the first direction (D1 direction shown in fig. 6) (i.e., the two second support plates 1232 are distributed in the D2 direction shown in fig. 6 and extend along the D1 direction shown in fig. 6), wherein the first support plate 1231 is perpendicular to an axis of the first through hole 121; the two second supporting plates 1232 are fixedly connected with the first supporting plate 1231, and an included angle between the second supporting plate 1232 and the first supporting plate 1231 is greater than or equal to 90 degrees; two second support plates 1232 and two elastic wings 122 are disposed above the first support plate 1231; two elastic tabs 122 are fixedly attached to the first support plate 1231 and between the two second support plates 1232. The structure of the supporting frame 123 can make the clamping and supporting portion 12 have better rigidity, so as to realize the fixing fastener and the fixing portion which can be stable for a long time while keeping in the groove.

Each of the elastic tabs 122 includes a bottom plate 1221, a vertical plate 1222, and a top plate 1223 connected to each other, wherein the bottom plate 1221 is fixed to the first support plate 1231, and the bottom plates 1221 of the two elastic tabs 122 are distributed on both sides of the first through hole 121 in the first direction; the vertical plate 1222 is formed to extend upward from a side of the bottom plate 1221 near the first through hole 121; a top plate 1223 is formed extending horizontally from the upper edge of the vertical plate 1222 in the first direction away from the axis of the first through hole 121, and abuts against the inner side surface of the lip of the opening of the groove 22. Viewed in the second direction, the resilient tab 122 presents a U-shape with an opening facing away from the axis of the first through hole 121. Optionally, a reinforcing rib 1225 structure is provided on the flexible flap 122 to enhance the strength of the flexible flap 122. The stiffener 1225 may be configured as a groove disposed on the resilient tab.

As above, the two elastic wings 122 are oppositely disposed along the first direction, and the two second support plates 1232 included in the support frame 123 are oppositely disposed along the second direction. When placing joint supporting part 12 in the recess of metal roofing, at first with the first direction (the D1 direction that figure 6 shows) of joint supporting part 12 be on a parallel with the stupefied extending direction's of room angle, place joint supporting part 12 in the recess, when placing, second backup pad 1232 upwards leans out, consequently, second backup pad 1232 can play the effect of direction, slides in recess 22. After the clamping support portion 12 is placed in the groove 22, the clamping support portion 12 is rotated by 90 °, then the second direction (D2 direction shown in fig. 6) of the clamping support portion 12 is parallel to the extending direction of the roof ridge, two elastic fins 122 oppositely arranged along the second direction abut against the inner surface of the lip of the opening of the groove 22, so that the clamping support portion 12 is clamped in the groove 22, and when the fixing portion 13 is screwed by the fastening member 11 so that the photovoltaic module is fixed on the metal roof, the fastening member 11 generates an upward force on the clamping support portion 12, as the clamping support portion 12 abuts against only the lower side of the lip of the opening of the groove 22 under the upward force, and the two elastic fins 122 gradually move away from each other under the effect, as the elastic fins 122 gradually move away, the upper surface of the elastic fins generates a greater pressure on the lower surface of the lip 221 of the opening of the groove 22, so that the clamping support portion 12 is tightly clamped in the groove 22.

In addition, in the first direction (direction D1 shown in fig. 6), the edge of the elastic wing 122 is flush with the edge of the second support plate 1232 or is located inside the edge of the second support plate 1232, and one side edge of the elastic wing 122 in the second direction (direction D2 shown in fig. 6) is connected to the second support plate 1232 by the connecting piece 1224, so that the 90 ° rotation can be performed without being hindered after the click support 12 is placed into the groove 22 in a direction parallel to the groove 22 in the first direction. In addition, the height of the elastic tab 122 is higher than the height of the second support plate 1232. This is because, as the fastening member 11 is tightened to clamp the supporting portion 12, the height of the elastic wing 122 is relatively reduced to be equal to the height of the second supporting plate 1232 after being forced to be spread, so that the upper surface of the elastic wing 122 and the upper edge of the second supporting plate 1232 abut against the lip 221 of the opening of the groove 22 at the same time, thereby achieving a stronger clamping. If the height of the elastic wing 122 is equal to or lower than the height of the second support plate 1232, after the elastic wing 122 is forced to be spread as the fastening member 11 is screwed to the clamping support portion 12, the height is reduced to be lower than the height of the second support plate 1232, so that the elastic wing cannot contact with the lip of the opening of the groove, only the upper surface of the second support plate 1232 of the clamping support portion 12 abuts against the lip 221 of the opening of the groove 22, so that the clamping strength between the clamping support portion 12 and the groove 22 is reduced.

In addition, in order to reinforce the strength of the supporting frame 123, notches 125 are formed at positions where the second supporting plate 1232, the first supporting plate 1231, and the outer wall of the first through hole 121 are connected to each other, so as to reinforce the strength of the second supporting plate 1232.

In addition, the fixing portion 13 may include two kinds of structures of the fixing portion 13 according to the different application positions of the fixing support structure 10.
