DETAILED DESCRIPTION

[0016] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0017] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] As mentioned in the background technology, there are multiple pairs of 2M heads in each row on the existing digital distribution frame in the substation, which are arranged closely. It is very inconvenient for the staff to tighten or remove them. When tightening, it is easy to fail to tighten properly, resulting in poor channel contact, interruption of the fiber multiplexing channel and other business interruptions; it is also difficult to remove, which often causes finger fatigue of the staff. Existing tools such as needle-nosed pliers are easy to damage the 2M head when operating, and it is easy to touch the running 2M head and cable, affecting the normal operation of the equipment.

[0019] Therefore, how to avoid hitting other running 2M heads and cables, and at the same time remove and tighten the 2M head more safely, reliably, simply and conveniently will become the improvement direction of this application. The idea of ​​this application is to set two clamping parts, clamp 2M heads of different specifications in the interface formed by the two clamping parts, and then the two extension parts form an adapter. By putting a screwdriver or other rotating tool on the adapter, the 2M head can be easily tightened or removed. In order to achieve the above purpose, a 2M head operation tool is provided.

[0020] join Figure 1 , which shows the specific structure of the operating tool of the 2M head of the present application. The operating tool of the 2M head includes a connecting device 1, which includes two clamping parts 111. The two clamping parts 111 can be spliced ​​to form a mating head 11 with a 2M head interface; the two clamping parts 111 are provided with articulated arms 12 respectively fixed to them and hinged to each other, and the two articulated arms 12 are respectively connected to an extension part 131, and the two extension parts 131 can be spliced ​​to form an adapter 13.

[0021] The 2M head is clamped by the two clamping parts 111, and the two extension parts 131 form an adapter 13. A screwdriver or other rotating tool can be put on the adapter 13 to tighten or remove the 2M head. It can adapt to 2M heads of different specifications.

[0022] It should be noted that the adapter 13 can be set as a whole to a shape that cooperates with an external tool. For example, the two extensions 131 are spliced ​​together to form a hexagonal prism structure, and the 2M head is rotated by a hexagonal tool. The adapter 13 can also be partially provided with a structure that cooperates with an external tool. For example, after the two extensions 131 are spliced ​​together, a groove or protrusion that cooperates with an external tool is formed on the adapter 13, and the 2M head is rotated by cooperating with a tool with a corresponding protrusion or groove.

[0023] See also Figures 2 to 5 Therefore, in a preferred embodiment, the operating tool of the 2M head further includes a rotating device 2, the rotating device 2 includes a connecting rod 21 and a connecting portion 22 provided at one end of the connecting rod 21, the connecting portion 22 cooperates with the adapter 13 to prevent the adapter and the connecting rod 21 from rotating relative to each other. By driving the connecting device 1 through the rotating device 2, no external tools are needed, which further improves the convenience of the operating tool of the 2M head.

[0024] As an implementation method, the connection part 22 is provided with a cavity, the adapter 13 is an inlay adapted to the cavity, the connection part 22 is provided with a first limiting structure 23, the adapter 13 is provided with a second limiting structure 14, and the first limiting structure 23 and the second limiting structure 14 can prevent the protrusion from rotating in the cavity when they cooperate. During installation, the inlay is extended into the cavity so that the first limiting structure 23 and the second limiting structure 14 cooperate with each other.

[0025] It can be seen from the previous embodiment that two pins can be eccentrically arranged on one of the connecting part 22 or the adapter 13, and a pin hole can be arranged on the other one. The connection is achieved by cooperating between the pin and the pin hole to prevent the adapter 13 and the connecting part 22 from rotating relative to each other, and it is not limited to the above embodiment.

[0026] Preferably, the connection part 22 is provided with a cylindrical cavity, the adapter 13 is a cylindrical convex block, the first limiting structure 23 is a missing part provided inside the connection part 22, and the second limiting structure 14 is a filling part provided outside the cylindrical convex block, the filling part matches the shape and size of the missing part, and the filling part can be placed in the missing part to achieve the limiting, which is convenient to operate and has high reliability. Furthermore, there are two missing parts and two filling parts, which are symmetrically provided on both sides of the connection part 22 and the adapter 13 respectively.

[0027] The rotating device 2 further includes a transmission mechanism 24 and an operating rod 25. The transmission mechanism 24 includes a housing 241. An inner gear 242 and an outer gear 243 that mesh with each other are provided in the housing 241. The outer gear 243 is fixedly connected to the operating rod 25, and the inner gear 242 is fixedly connected to the connecting rod 21. The operating rod 25 is rotated to drive the outer gear 243, and the outer gear 243 drives the inner gear 242 to rotate. The inner gear 242 drives the connecting rod 21 to rotate. The connecting rod 21 then rotates the connecting tool through the adapter 13, thereby increasing the torque of the operating rod 25 and making the entire rotation process more labor-saving.

[0028] A planetary gear 244 is provided between the outer gear 243 and the inner gear 242, and the planetary gear 244 is respectively engaged with the outer gear 243 and the inner gear 242. The load of the outer gear 243 is distributed to the planetary gear 244, and the load is then transmitted to the inner gear 242 through the planetary gear 244, which reduces the force on the outer gear 243 and the inner gear 242 compared with the above solution.

[0029] There are three planetary gears 244, which are evenly distributed between the outer gear 243 and the inner gear 242 along the circumferential direction, so that the forces between the planetary gears 244 and the rotating arm can be balanced. At the same time, the number of teeth involved in the meshing is increased, so the planetary gears 244 drive the movement smoothly, have a strong ability to resist impact and vibration, and work more reliably.

[0030] It should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0031] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
