The first mounting stage 50 is directly or indirectly fixed to a surface of the support plate 20. To facilitate gripping, the first fastener 40 has a thickness. The first mounting table 50 is used for fixing the first fixing member 40. The thickness of the first mounting table 50 can be adjusted according to the thickness of the first fixing member 40, so as to ensure the stability of the connection between the first fixing member 40 and the first mounting table 50. The addition of the first mounting table 50 to the fixed clamping device 10 avoids the support plate 20 from being too thick, thereby achieving a lightweight design.

The fourth through hole 501 communicates with the second through hole 204. The shape of the fourth through hole 501 may be the same as or different from the shape of the second through hole 204.

The fourth through hole 501 and the second through hole 204 are communicated in at least two communication modes. One communication method is as follows: the fourth through hole 501 is directly connected with the second through hole 204. The second communication mode is as follows: the fourth through hole 501 and the second through hole 204 are spaced by a certain space, but the projection of the fourth through hole 501 to the second surface 202 and the second through hole 204 have an overlapping portion, and the overlapping portion may surround the distal steel nail 120.
