[0019] The first supporting module 4 comprises a first supporting rod 41, a second supporting rod 42, a ratchet 43, a clamping rod 44 and a sliding block 45. One end of the first supporting rod 41 is hinged to the mounting clamping rail 31 through a rotating shaft, and the other end of the first supporting rod 41 is hinged to one end of the second supporting rod 42 through a rotating shaft. The other end of the second supporting rod 42 is provided with a ratchet 43. The ratchet 43 is installed between the top plate and the bottom plate of the mounting seat 33 through the rotating shaft. The ratchet 43 is adapted to the clamping rod 44 and the two are engaged. The clamping rod 44 is arranged in the guide groove 34, and a sliding block 45 is arranged at one end of the clamping rod 44 away from the ratchet 43, and the sliding block 45 is slidably connected to the slide rail. A spring 6 is arranged at one end of the clamping rod 44 away from the ratchet 43. Under the elastic force of the spring 6, the clamping rod 44 is pressed against the ratchet 43 and clamped. A sliding block 45 is arranged at one end of the clamping rod 44 away from the ratchet 43, and the sliding block 45 is slidably connected to the slide groove 35.

[0020] The second supporting module 5 is similar to the first supporting module 4 .

[0021] Among them, the chassis 1 is a protective shell, and the fixing mechanism is used to install the optical communication equipment. The fixing mechanism is composed of a first clamping component 3 and a second clamping component 2 with the same structure. The first clamping component 3 and the second clamping component 2 are symmetrically arranged on the two inner walls of the chassis 1 respectively. The first clamping component 3 and the second clamping component 2 cooperate to provide installation and fixing components for the corresponding optical communication equipment; the first support module 4 and the second support module 5 are arranged between the mounting seat 33 and the mounting rail 31. The space of the mounting rail 31 is large, and a large-sized device can be inserted into the card slot at the mounting rail 31. Then, a fastening bolt is installed at the fixing hole 32 at the top of the mounting rail 31, so that the fastening bolt is squeezed against the top of the optical communication equipment and clamped. The optical communication equipment can be fixed at the mounting rail 31 without drilling holes for the optical communication equipment.
