[0027] By covering the right fixed arc plate 3 and the left fixed arc plate 4 on the surface of the cable rubber sleeve 1, the right fixed arc plate 3 and the left fixed arc plate 4 are rotated inward synchronously, so that the fixed plate 12 is inserted into the limit frame 8, and the second rotating rod 16, the fixed plate 12 and the limit ring 15 are set, so that the fixed plate 12 can be easily inserted into the limit frame 8, and the one-way engagement of the first tooth block 14 and the second tooth block 13 is set, so that the fixed plate 12 can move to the left, and the fixed plate 12 is limited by the set spring 10 and the limit plate 11, so that the first tooth block 14 is limited, making it difficult for the fixed plate 12 to move to the right, so that the right fixed arc plate 3 and the left fixed arc plate 4 are fixed on the surface of the cable rubber sleeve 1, thereby completing the rapid positioning and installation of the device.

[0028] The top of the left fixed arc plate 4 is fixedly connected to a first connecting tube 6, and the top of the right fixed arc plate 3 is fixedly connected to a second connecting tube 5.
