[0019] As Figures 1 to 2 shown, a sealing and coding mechanism 3 is rotatably provided through one side of the base 1, and a metering roller 4 is hermetically attached to the outer periphery of the sealing and coding mechanism 3. Both ends of the metering roller 4 are rotatably connected to the sealing and coding mechanism 3 and the roller housing 7 respectively through the first bearings 6, and the roller housing 7 is hermetically fixed to the other side of the base 1; a cable pressing mechanism 2 is fixedly provided at the upper end of the base 1, and a gap for the cable to pass through is left between the cable pressing mechanism 2 and the metering roller 4; a watertight cable 5 is provided at the bottom of the sealing and coding mechanism 3, and the watertight cable 5 is electrically connected to the sealing and coding mechanism 3.

[0020] The sealing and coding mechanism 3 includes a sealing shell 8, a magnetic coupling 9 and an encoder 10.

An encoder 10 is fixedly provided inside the magnetic coupling 9, and the outside of the magnetic coupling 9 is fixedly connected to the inside of the metering roller 4; a watertight cable 5 is provided on the magnetic coupling 9. Specifically, in this embodiment, the magnetic coupling 9 includes an isolation sleeve 11, an inner magnetic circuit 12 and an outer magnetic circuit 13. A first sealing ring 14 is clamped between one end of the sealing shell 8 and the isolation sleeve 11.

[0025] The cable passes through between the length measuring roller 4 and the cable pressing roller 19, and drives the length measuring roller 4 to rotate through the friction force with the anti-slip layer 21. The outer magnetic circuit 12 of the magnetic coupling 9 is fixed inside the length measuring roller 4 and rotates at the same speed and synchronously with it. Through the magnetic force, the isolation sleeve 11 drives the inner magnetic circuit 12 to rotate at the same speed and synchronously, so that the digital signal generated by the magnetic coupling 9 is transmitted to an external control terminal through the watertight cable 5 to obtain the length measuring indication.
