Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1: as shown in fig. 1, the utility model discloses be I-shaped, first splint 1 and second splint 2 including longitudinal symmetry, the bottom of first splint 1 and the upper portion of second splint 2 all be equipped with centre gripping groove 11, the inner wall fixedly connected with silica gel pad 12 of centre gripping groove 11 for protection photovoltaic board surface does not receive the damage. First splint 1 is fixed through threaded rod 3 with second splint 2, is provided with gland plate 6 between threaded rod 3 and the second splint 2. First splint 1 bottom is provided with two connecting pieces 4, two connecting pieces 4 are located the both sides of threaded rod 3, be provided with in the second splint and hold cavity 5, it is provided with two ascending direction extension pieces 51 to hold cavity 5, two direction extension pieces 51 are located 3 both sides of threaded rod and slide and are provided with roof pressure piece 52, roof pressure piece 52 middle part and 3 screw-thread fit of threaded rod, thereby by the driven oscilaltion of threaded rod 3, two connecting pieces 4 are extruded by roof pressure piece 52 both ends respectively, thereby form fixed connection with the inner wall that holds cavity 5. The inside of first splint 1 is equipped with blind hole 7, and the tail of threaded rod 3 is arranged in blind hole 7, is provided with buffer spring 71 in the blind hole 7, and buffer spring plays the effect of protection and connection buffering.

As shown in fig. 2, the pressing member 52 includes a fixing ring 521 screw-engaged with the threaded rod 3, connecting blocks 22 fixed to both side walls of the fixing ring, and a rotating wheel 523 connected to the top end of the connecting block 522.
