One end of the melting type tray 12 is located in the sliding groove 111, the other end of the melting type tray 12 is located outside the sliding groove 111 all the time, and baffles can be arranged on two sides of one end of the melting type tray 12 located outside the sliding groove 111, so that the melting type tray 12 can be pulled out conveniently.
The fused fiber tray 12 comprises a fiber storage tray 121 and a fusion welding tray 122, the fiber storage tray 121 and the fusion welding tray 122 are rectangular trays, the fiber storage tray 121 and the fusion welding tray 122 are arranged in a stacked mode, and the fiber storage tray 121 is located above the fusion welding tray 122. The baffle can be arranged on one of the fiber storage tray 121 or the fusion splice tray 122, or can be divided into an upper part and a lower part, wherein the upper part is positioned on the fiber storage tray 121, and the lower part is positioned on the fusion splice tray 122.
The side of the fiber storage disc 121 facing away from the splice disc 122 forms a first operation area 1216, and the first operation area 1216 is provided with a first disc fiber wheel 1211, a tail fiber connector buckle 1212, a tail fiber inlet 1215 and a tail fiber outlet 1213. The first fiber reel 1211 can be used for winding and storing the tail fiber, the tail fiber connector buckle 1212 can be used for fixing the tail fiber connector at the end of the tail fiber, the tail fiber inlet 1215 is used for introducing the tail fiber, and the tail fiber outlet 1213 penetrates through the bottom plate of the fiber storage disc 121 and is used for leading out the tail fiber in the first operation area 1216.
The splice tray 122 forms a second operational area 1226 adjacent to the fiber storage tray 121, and a second tray wheel 1222, a cable tray wheel 1221, a splice protection tube holder 1223, and a cable entry 1224 are disposed in the second operational area 1226.

When the burn-in tray 12 is in the first state, operation can be performed in the first operation area 1216, where the second operation area 1226 is blocked by the fiber storage tray 121. When the fuse tray 12 is in the second state, the second operation area 1226 is unblocked by the fiber storage tray 121, and operation can be performed in the second operation area 1226.
In the using process, when the pigtails need to be used, the melting-storage tray 12 is pulled out to be operated in the first operation area 1216, the pigtail storage tray 121 and the splice tray 122 do not move relatively, and the pigtails between the pigtail storage tray 121 and the splice tray 122 can be effectively prevented from being damaged and broken.

In one embodiment of the present invention, the fiber storage tray 121 is rotatably connected to the fusion splice tray 122, and the fusion splice tray 12 is switched from the first state to the second state by rotating the fiber storage tray 121.
Optionally, the fiber storage tray 121 is rotatably connected to the splice tray 122 through a hinge shaft, the hinge shaft is disposed on one side of the splice tray 122 and the fiber storage tray 121, and an axis of the hinge shaft is parallel to a side surface of the splice tray 122 close to the fiber storage tray 121. Specifically, the hinge shaft may be provided at an end of the melting tray 12 located in the slide groove 111. When the deposit tray 12 is in the first state, the fiber deposit tray 121 and the splice tray 122 are stacked in parallel with each other. The fibre storage tray 121 is rotated about the hinge axis so that the fibre storage tray 121 is no longer parallel to the splice tray 122 and is free to escape the second operating zone 1226, with the splice tray 12 in the second state.
Further, the tail fiber outlet 1213 is arranged at the corner of the fiber storage disc 121, the hinge shaft is arranged on the side of the fiber storage disc 121 close to the tail fiber outlet 1213, and when the fiber storage disc 121 is rotated, the traction on the tail fiber between the fiber storage disc 121 and the fusion welding disc 122 is small, so that the damage to the tail fiber can be avoided.
In an embodiment of the present invention, the fiber storage tray 121 is detachably connected to the splice tray 122, and the fused tray 12 is switched from the first state to the second state by detaching the fiber storage tray 121 from the splice tray 122. It should be noted that, because the number of operations on the splice tray 122 is small during the use, the fusible tray 12 is not always switched to the second state, and the relative displacement between the splice tray 121 and the splice tray 122 can be reduced to protect the pigtails when the splice tray 121 is used. Even if the fiber storage disc 121 is switched from the first state to the second state by detaching the fiber storage disc 121 from the fusion splice disc 122, the protection effect is better than that of the prior art in which only the fiber storage disc 121 is pulled. In order to prevent the tail fibers between the fiber storage tray 121 and the fusion splice tray 122 from being damaged in the process of detaching the fiber storage tray 121 from the fusion splice tray 122, a length for moving the fiber storage tray 121 can be reserved on the tail fibers between the fiber storage tray 121 and the fusion splice tray 122.
