That is, the second mounting hole 211 may partially face the first mounting hole 111 or may completely face the first mounting hole 111.
The fastener 300 includes: a stem part 310 and a head part 320, the head part 320 being connected to the top end of the stem part 310, and the head part 320 extending in the radial direction of the stem part 310. That is, the head 320 of the fastener 300 is different from the head of a conventional fastener in that it extends in a radial direction and is restrained and fixed. The rod portion 310 is inserted into the second mounting hole 211 and then is engaged with the first mounting hole 111, the head portion 320 is located outside the second mounting hole 211, and the head portion 320 and the second mounting hole 211 are arranged in a staggered manner. By arranging the head 320 and the second mounting hole 211 in a staggered manner, the problem that the frame 210 is unstable due to the fact that the head 320 is separated from the second mounting hole 211 after the fastener 300 is used for fixing the frame 210 can be avoided.
When the fastener 300 is fixed, after the rod portion 310 penetrates through the first mounting hole 111 and the second mounting hole 211, the head portion 320 rotates to a position avoiding the second mounting hole 211, and then the frame 210 is pressed on the rail 110, so that the fixation of the frame 210 on the rail 110 can be ensured, and the mounting efficiency can be improved.
