[0002] At present, the control circuit of thermal power plant equipment mainly transmits signals through cables. Affected by the on-site environment (such as high temperature environment, vibration environment, etc.), the cable core is easily damaged, and the damaged part of the cable needs to be replaced to ensure the normal operation of the equipment. Replacing the cable mainly involves twisting the cable core together, and the cable generally has an outer sheath that provides flame retardancy and low acid resistance, so it needs to be stripped before twisting.

[0003] The existing devices mainly use handheld cable cutters to strip cables, which makes it difficult for some devices to stably convey the cables through the blades, causing some cables to easily slide on the inner wall of the winding reel. At the same time, it is difficult for some devices to adjust the height of the cutter according to the specifications of the cable, which makes it difficult for some devices to accurately strip the cables, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a special winding reel for cable stripping is proposed. Utility Model Content
