Abstract
The invention discloses a holding type cable protection device comprising a pipe body which sleeves the periphery of a cable. An expander is arranged between the inner wall of the pipe body and the peripheral surface of the cable. The expander includes a downward pressing block which fits and matches the peripheral surface of the cable. One end of the downward pressing block is provided with a datum plate. The top of the downward pressing plate is provided with a first guide surface. The gap between the first guide surface and the bottom surface of the downward pressing block gradually increases from the end near the datum plate to the end away from the datum plate. An upward pressing block which fits and matches the inner wall of the pipe body is arranged above the downward pressing plate. The bottom of the upward pressing block is provided with a second guide surface which is parallel to and fits the first guide surface. One end of the upward pressing block is provided with an adjusting screw which penetrates through the datum plate along the axial direction of the pipe body. The holding type cable protection device of the invention has a good cable protection effect and higher safety.
