The working principle of the invention is as follows:

an optical cable is inserted into the device from a feeding pipe 1-1, a driving wheel 2-1 is in contact with the optical cable and rotates on the feeding pipe 1-1 along with the insertion of the optical cable, the driving wheel 1-1 stretches and compresses a distance measuring air bag 2-5 through a linkage rod 2-2 when rotating, the distance measuring air bag 2-5 infuses air into an air pressure box 2-3, the infused air enters a hydraulic pressure box 2-4 through the air pressure box 2-3 and a transmission pipe, the air pressure in the hydraulic pressure box 2-4 is continuously enhanced and solution in the hydraulic pressure box is squeezed, the solution in the hydraulic pressure box 2-4 continuously and slowly rises in a distance measuring pipe 2-6, and a detection system measures the height of the solution in the distance measuring pipe 2-6, so that the length of the optical cable is obtained.

When an optical cable enters the device, the moving ring 3-1 is driven by the transverse moving machine to move to the right end of the feeding pipe 1-1, meanwhile, when the driving wheel 2-1 rotates for a certain number of turns, the two groups of telescopic cylinders 3-6 simultaneously enable the two groups of clamping jaws 3-7 to be in contact with the optical cable, the bending air bags 3-73 enable the bone sections 3-72 to rotate relatively after being inflated, so that the clamping jaws 3-7 clamp the optical cable, after the optical cable is clamped by the clamping jaws 3-7, the transverse moving machine drives the moving ring 3-1 to move to the right end of the shell 1 and loosen the optical cable, and the optical cable is pushed by external force to extend out of the shell 1.

When the detection system detects that the height of the solution in the distance measuring pipe 2-6 reaches a set value, the electromagnetic valve in the transmission pipe is closed, the transmission wheel 2-1 continues to compress the distance measuring air bag 2-5, so that overflowed air in the air pressure tank 2-3 is temporarily stored in the transmission pipe, and air in the hydraulic pressure tank 2-4 is released out of the device, and the hydraulic pressure tank 2-4 is convenient to measure the length of the optical cable again.

When the length of the optical cable reaches a set value, the moving ring 3-1 is positioned at the right side of the feeding pipe 1-1, when the driving wheel 2-1 rotates to a certain number of turns, namely the set number of turns in a control system of the device, the position where the optical cable needs to be cut is just positioned at the middle position of the two groups of clamping jaws 3-7 and is positioned under the upper group of cutting tools 3-5, the moving ring 3-1 moves along with the optical cable under the driving of transverse movement, meanwhile, the clamping jaws 3-7 clamp the optical cable, after the optical cable is clamped by the clamping jaws 7, the adsorption air bags 3-74 are filled with gas, so that the clamping force of the clamping jaws 3-7 on the optical cable is increased, meanwhile, non-Newtonian fluid in the solidification air bags 3-75 is solidified under the action of external force, the shapes of the clamping jaws 3-7 are fixed, and the clamping jaws 3-7, after the adsorption air bags 3-74 are filled with air, the adsorption discs 3-76 perform negative pressure adsorption on the optical cable, so that the connection between the clamping jaws 3-7 and the optical cable is tighter.

When the three groups of cutting tools 3-5 cut the optical cable under the control of the fine adjustment cylinders 3-4, the three groups of cutting tools 3-5 are driven by the power box 3-3 to move rapidly on the rotating ring 3-2, and the three groups of cutting tools 3-5 rotate rapidly and continuously cut the optical cable inwards to cut the optical cable, so that the optical cable is cut in the moving process of the optical cable.

When the optical cable is cut, the contraction air bag 4-1 is infused with gas, so that the friction force between the optical cable and the device is increased, an operator can know that the optical cable is being cut and needs to slowly pull, after the optical cable is cut, the contraction air bag 4-1 is restored to the original state, namely, the state of not being in contact with the optical cable, the cut optical cable is drawn out of the device, and meanwhile, the other end of the device still continuously enters the optical cable.

At the moment, the deflection box 3-9 on the left side drives the clamping jaws 3-7 to rotate towards the left side and clamp the optical cable in the device, in the deflection process of the deflection box 3-9, the clamping jaws 3-7 are always kept in a horizontal state through the balance blocks 3-8, so that the clamping jaws 3-7 can be quickly parallel to the optical cable and clamp the optical cable, after the clamping jaws 3-7 on the left side clamp the optical cable, the deflection box 3-9 starts to reset, simultaneously, the optical cable is pulled due to the resetting of the clamping jaws 3-7, the speed of entering the device is high, when the clamping jaws 3-7 on the left side clamp the optical cable, the clamping jaws 3-7 on the right side are in an unfolded state, namely, a plurality of bone sections 3-72 are in a horizontal state with the middle plate 3-71, the optical cable is reset by the clamping jaws 3-7 on the left side, the other end of, the clamping jaws 3-7 on the right side pull the optical cable again under the driving of the deflection boxes 3-9 on the right side, and send the optical cable out of the device.
