More specifically, the first abutment 22 and the first sliding member 23 are connected together by threads; the second abutment 32 and the second sliding member 33 are connected together by threads.

[0047] More specifically, both the first abutting member 22 and the second abutting member 32 have abutting surfaces facing the mounting plate 1, and abutting portions 221 and 321 protrude from the mounting plate 1 on the abutting surfaces; the first sliding member 23 and the second sliding member 33 have pressing portions at one end near the mounting plate 1; wherein, when the first sliding member 23 passes through the first sliding groove 11 and is installed on the first abutting member 22, the abutting portion 221 of the first abutting member 22 and the pressing portion of the first sliding member 23 are respectively pressed against both sides of the mounting plate 1; when the second sliding member 33 passes through the second sliding groove 12 and is installed on the second abutting member 32, the abutting portion 321 of the second abutting member 32 and the pressing portion of the second sliding member 33 are respectively pressed against both sides of the mounting plate 1.
