Subsequently, the size of the second installation groove 302 can be adjusted by pushing the second adjusting plate 307 to move inside the second limiting groove 304 and the fourth limiting groove 325. When the second adjusting plate 307 is in place, place the second fixing piece 305 and the third fixing piece 309 on the top and bottom of the second adjusting plate 307 respectively. Insert the bolt 4 into the inside of the fifth fixing groove 306, the sixth fixing groove 308, and the eighth fixing groove 319 respectively, so as to fix the position of the second adjusting plate 307 and prevent it from moving again. And the depth of the second installation groove 302 can be adjusted by pushing the fourth adjusting plate 320 to move, and the movement of the fourth adjusting plate 320 drives the guide plate 316 to move inside the guide groove 317.
