DETAILED DESCRIPTION

[0013] The utility model is further described below with reference to the accompanying drawings.

[0014] like Figure 1-Figure 2 As shown, cable fixing devices 2 are provided on the left and right sides above the base 1, and branching fixing devices 3 are provided in the middle and front and rear sides between the cable fixing devices 2. The interior of the base 1 is a cavity structure, and a screw rod 4 is provided in the cavity. The threads on both sides of the screw rod 4 have opposite rotation directions. The branching fixing devices 3 on the front and rear sides are respectively connected to the screw rod 4 through nuts 5, and the middle branching fixing device 3 is fixedly connected to the base 1.

[0015] A bevel gear 1 4 - 1 is provided at one end of the screw rod 4 , a vertical rotating shaft 6 is provided at one side of the base 1 , a bevel gear 2 6 - 1 is fixed on the rotating shaft 6 , the bevel gear 1 4 - 1 is meshed with the bevel gear 2 6 - 1 , and the top of the rotating shaft 6 is exposed from the base 1 .

[0016] The top of the rotating shaft 6 is hexagonal.

[0017] The branch line fixing device 3 includes a clamping block 1 3-1 and a clamping block 2 3-2. One side of the clamping block 1 3-1 is hinged to one side of the clamping block 2 3-2. The other side of the clamping block 1 3-1 is locked with the clamping block 2 3-2 by a screw 1 3-4. A cable hole 3-3 is provided between the clamping block 1 3-1 and the clamping block 2 3-2. The clamping block 2 3-2 is provided with a screw 2 3-5 above the cable hole 3-3. The structure of the cable fixing device 2 is the same as that of the branch line fixing device 3.

[0018] Two groups of branch line fixing devices 3 are arranged in parallel.

[0019] When the utility model is used, the cable 7 is first clamped in the cable fixture 2 on one side, and then the branch line 7-1 is clamped in the branch line fixture 3. An external hexagonal sleeve can be used to cover the hexagonal top of the shaft 6, and the shaft 6 is rotated. The bevel gear 2 6-1 is meshed with the bevel gear 1 4-1, driving the screw 4 to rotate. The threads on both sides of the screw 4 rotate in opposite directions, which can drive the nuts 5 on both sides to move closer or separate, so that the branch line fixtures 3 on both sides move closer to the middle or separate to both sides, and can be adjusted to the required distance for maintenance. The branch line fixture 3 is arranged in parallel with two groups, which can adjust the branch line 7-1 to a parallel direction, and there can be more space for convenient maintenance operations.

[0020] A semicircular groove is provided above the clamping block 1 3-1 and below the clamping block 2 3-2, and a cable hole 3-3 is formed after closing. When fixing the branch line 7-1, the clamping block 2 3-2 is first opened, and the branch line 7-1 is placed in the groove above the clamping block 1 3-1, and then the clamping block 2 3-2 is rotated and closed to lock the screw 1 3-4, so that the clamping block 1 3-1 and the clamping block 2 3-2 are fixed, and then the screw 2 3-5 is locked to fix the branch line in the cable hole 3-3. The cable fixing device 2 can adopt the same clamping structure as the branch line fixing device 3, and the middle cable hole 3-3 can be enlarged to accommodate a cable 7 that is thicker than the branch line 7-1.
