The connector 400 provided with at least two ferrule mounting holes can accommodate at least one optical fiber 800, and at least two optical fibers 800 can be simultaneously installed in the multi-core optical fiber loop device provided with at least two connectors 400.

Meanwhile, the push-pull rod 100 is further provided with an upper shell 200 and a lower shell 300, wherein the lower shell 200 is in sliding connection with the push-pull rod 100, the lower shell 300 is in buckling connection with the upper shell 200, the upper shell 200 and the lower shell 300 are buckled to form a containing cavity for containing the optical fiber wire body, and the connector 400 is connected with the upper shell 200 and the lower shell 300 to communicate the ferrule mounting hole with the containing cavity. After the optical fiber 800 is installed in the multi-core optical fiber loop device, the wire body of the optical fiber 800 is contained in the containing cavity formed by the upper shell 200 and the lower shell 300, a plurality of optical fibers 800 can be installed in the multi-core optical fiber loop device with at least two connectors 400 at the same time, when a plurality of optical fibers 800 are connected with the connecting interfaces on the optical fiber 800 device, the plurality of optical fibers 800 can be spliced on the connecting interfaces only by one multi-core loop device, the operation is very convenient, and after the optical fibers 800 are installed in the multi-core optical fiber loop device, the wire body and the inserting core 600 are all positioned in the cavity, and no part exposed to the external environment is avoided, so that the optical fibers 800 are prevented from being damaged by the outside.
In another embodiment, as shown in fig. 5-6, the accommodating cavity for accommodating the fiber 800 may also be formed by a front frame sleeve 210 and a rear frame sleeve 310, where the front frame sleeve 210 and the rear frame sleeve 310 are both disposed on the push-pull rod 100, and the front frame sleeve 210 and the rear frame sleeve 310 are in snap connection, where the front frame sleeve 210 includes a first connection end 211 and a second connection end 212, the first connection end 211 is connected with the connector 400, the second connection end 212 is connected with the rear frame sleeve 310, a first accommodating cavity 213 is disposed in the front frame sleeve 210, a second accommodating cavity 311 is disposed in the rear frame sleeve 310, and the first accommodating cavity 213 is respectively communicated with the ferrule mounting hole and the second accommodating cavity 311 to jointly form a cavity for accommodating the fiber 800.
The wall of the front frame 210 is further provided with a wire inlet 214, the wire inlet 214 extends from the first connecting end 211 to the second connecting end 212, and the wire inlet 214 is communicated with the first accommodating cavity 213. When the optical fiber 800 is installed in the optical fiber loop device, the two ends of the optical fiber 800 are respectively inserted into the inserting cores 600, and are communicated to the interface of the external optical fiber 800 through the inserting cores 600, and the two ends of the optical fiber 800 inserted into the inserting cores 600 are inserted into the inserting core mounting holes, so that the wire body of the optical fiber 800 is exposed outside. The wire inlet 214 facilitates the user to load the wire body of the optical fiber 800 into the front bezel 210 from the wall of the front bezel 210, avoiding the need to bend substantially when the wire body is loaded into the front bezel 210, and thus preventing damage to the wires in the optical fiber 800. In this embodiment, the wire inlet 214 extends from the beginning end of the first connecting end 211 to the end of the second connecting end 212, that is, the wire inlet 214 penetrates through the beginning and end ends of the front frame sleeve 210, so as to load the wire body of the optical fiber 800 into the first accommodating cavity 213.
The wire inlet 214 extends from the first connection end 211 to the second connection end 212 in a bending manner to prevent the optical fiber 800 from being separated from the first receiving cavity 213. After the two ends of the optical fiber 800 are inserted into the ferrule mounting holes, the wire body at the rear end is approximately in a "U" shape, but the opening end of the "U" shape is smaller than the bottom end, so that, in order to avoid the optical fiber 800 from separating from the first accommodating cavity 213, the extension shape of the wire inlet 214 may be an "S" shape or a "C" shape.

On the one hand, the buckle groove 204 is arranged in the buckle groove 204 after the buckle 302 penetrates out of the buckle position, and is not protruded out of the surface of the upper shell 200, so that the buckle 302 is effectively prevented from being separated from the buckle position due to false touch and other factors, and on the other hand, when the upper shell 200 and the lower shell 300 are required to be separated, the buckle 302 can be pushed from the buckle groove 204 to be separated from the buckle position.
In an embodiment, an end of the upper case 200 connected to the connector 400 is provided with a wire inlet slot 201, and a slot opening of the wire inlet slot 201 faces the lower case 300.

Meanwhile, after the limiting block 111 and the limiting hole 301 are matched, the push-pull rod 100 can be prevented from tilting (when the push-pull rod 100 is deformed to a certain extent, the limiting block 111 is limited by the side wall of the limiting hole 301), so that the push-pull deformation of the push-pull rod 100 is avoided, the service life of the push-pull rod 100 is prolonged, and the reliability is improved.
