The elastic force released by the spring 5 is applied to the movable plate 3, so that the two sides of the movable plate 3 are tightly attached to the first groove 21. At the same time, the friction between the threaded groove 41 and the threaded hole 15 is increased to generate a resistance torque, so that the drive rod 4 is fixed in the position after the activity, thereby enhancing the connection reliability.

[0035] When the cable branch box body 2 needs to be disassembled, the disassembly can be completed by simply rotating the hand wheel 42 in the opposite direction.

[0036] The above design scheme can make the product have the advantages of easy disassembly and assembly, convenient maintenance and good adaptability.
