The fixing and connecting method in this embodiment includes, but is not limited to, bolting, welding, and the like.

As shown in fig. 1-4, when the device of the present invention is in an initial state, the pressing slider 29 and the contact switch 27 are in an abutting state, the main pressing block 25 is completely located in the main pressing block cavity 23, the auxiliary triggering magnetic block 36 and the main triggering magnetic block 42 are not in a corresponding state, the auxiliary triggering magnetic block 36 and the left end wall of the auxiliary triggering magnetic block cavity 38 are in a close-fitting state, the driving gear 59 and the pressing gear 55 are in a meshing state, and the main adjusting friction wheel 49 and the auxiliary adjusting friction wheel 46 are in an abutting state;

sequence of mechanical actions of the whole device:

in operation, the cable 17 is placed in the main pulling chamber 16 through the cable inlet chamber 15, and the optical cable 17 is positioned between the upper friction roller 14 and the lower friction roller 19 and is in a state of abutting against the lower friction roller 19, at this time the motor 31 is started in a forward direction, thereby driving the spline shaft 32 to rotate, the spline shaft 32 drives the driving gear 59 to rotate through the switching main shaft 60, thereby driving the pressing gear 55 to rotate, thereby driving the pressing shaft 30 to rotate, thereby driving the pressing slide block 29 to move downwards, the pressing slide block 29 drives the auxiliary pressing block 45 to move downwards through the auxiliary pressing block cavity 26 and the pressing spring 24, the auxiliary pressing block 45 drives the upper friction roller 14 to move downwards through the upper friction roller shaft 13, the upper friction roller 14 moves downwards along with the downward abutment of the upper side of the optical cable 17, so that the lower friction roller 19 is matched to achieve an automatic pressing effect on the optical cable 17, and the optical cable 17 is prevented from slipping in the subsequent traction process;

meanwhile, the reaction force of the optical cable 17 on the upper friction roller 14 drives the auxiliary pressing block 45 to move upwards relative to the main pressing block 25 by overcoming the thrust of the pressing spring 24 through the upper friction roller 14 and the upper friction roller shaft 13, simultaneously, the pressing spring 24 is in a gradually compressed state, and when the main pressing block 25 moves downwards, the main magnetic through cavity 11 and the auxiliary triggering magnetic block cavity 38 are in a corresponding state, so that when the auxiliary pressing block 45 moves upwards relative to the main pressing block 25, the main triggering magnetic block 42 moves upwards relative to the main magnetic through cavity 11 along with the auxiliary pressing block 45 and corresponds to the auxiliary magnetic through cavity 40, and at the moment, the main triggering magnetic block 42 generates a certain attractive force to the auxiliary triggering magnetic block 36 through the auxiliary magnetic through cavity 40 and the main magnetic through cavity 11, so that the auxiliary triggering magnetic block 36 moves rightwards, the triggering pull rope 37 is in a tensioned state, and the switching slider 61 overcomes the thrust of the switching slider spring 62 to move downwards under the action of the pulling force of the triggering slider 37, therefore, the switching slide block 61 drives the driving gear 59 to move downwards to be just in a meshed state with the traction gear 56 through the switching main shaft 60, and at the moment, the driving gear 59 is in a separated state with the pressing gear 55, so that the pressing gear 55 stops rotating, namely the upper friction roller 14 stops moving downwards, namely the optical cable 17 is stopped being pressed, and therefore reaction force with corresponding magnitude generated due to the compression amount of the pressing spring 24 can generate corresponding pressing effect on the optical cable 17 through the upper friction roller 14;

if the pressing force generated by the upper friction roller 14 on cables with different sizes needs to be adjusted, the pressure adjusting knob 12 is rotated in the initial state to drive the pressure adjusting spindle 39 to rotate, so as to drive the main adjusting friction wheel 49 to rotate, because the main adjusting friction wheel 49 and the auxiliary adjusting friction wheel 46 are in the abutting state in the initial state, the main adjusting friction wheel 49 drives the auxiliary adjusting friction wheel 46 to rotate, so as to drive the main bevel gear shaft 47 to rotate, the main bevel gear shaft 47 drives the auxiliary bevel gear 50 to rotate through the main bevel gear 48, so as to drive the auxiliary bevel gear 50 to rotate, so as to drive the baffle adjusting shaft 43 to rotate, so as to drive the baffle adjusting slider 44 to move upwards, so as to drive the magnetic blocking baffle 41 to move upwards, so that the distance between the auxiliary magnetic through cavity 40 and the main triggering magnetic block 42 is increased, so that when the main triggering magnetic block 42 and the auxiliary magnetic through cavity 40 correspond again, the upward movement distance of the auxiliary pressing block 45 relative to the main pressing block 25 is increased, so that the compression amount of the pressing spring 24 is increased, the reaction of the pressing spring 24 on the optical cable 17 through the upper friction roller 14 is increased, the pressing effect of the optical cable 17 is enhanced, and when the pressure adjusting knob 12 is reversed, the pressing effect on the optical cable 17 can be weakened, so that the device can adapt to the traction work of optical cables 17 of different types, and the universality of the device is improved;

meanwhile, the driving gear 59 and the traction gear 56 are in a meshed state at the moment, so that the driving gear 59 drives the traction gear 56 to rotate, the traction shaft 33 is driven to rotate, the traction shaft 33 drives the main transmission bevel gear 21 to rotate through the auxiliary transmission bevel gear 34, the lower friction roller shaft 20 is driven to rotate, the lower friction roller 19 is driven to rotate, the friction force between the lower friction roller 19 and the optical cable 17 is generated at the moment, and the optical cable 17 is pulled forwards by matching with the rotation of the lower friction roller 19, so that the optical cable 17 is driven to move;

when the traction is finished, the motor 31 is turned off at the moment, then the manual knob 28 is rotated for one circle, so that the pressing shaft 30 is driven to rotate reversely, the pressing slider 29 is driven to move upwards, the main pressing block 25 is driven to move upwards, the auxiliary pressing block 45 is pushed by the pressing spring 24 to move downwards relative to the main magnetic through cavity 11 at the moment, the main triggering magnetic block 42 is driven to move downwards relative to the auxiliary magnetic through cavity 40, the main triggering magnetic block 42 and the auxiliary triggering magnetic block 36 are in a separation corresponding state, the auxiliary triggering magnetic block 36 loses the attraction of the main triggering magnetic block 42 at the moment, the triggering pull rope 37 is in a loosening state, the switching slider 61 loses the pulling force of the triggering pull rope 37, the switching slider 61 moves upwards under the pushing force of the switching slider spring 62, and the switching slider 61 drives the driving gear 59 to move upwards through the switching main shaft 60 to be in a meshing state with the pressing gear 55 again, thereby reverse starter motor 31 this moment to motor 31 drives integral key shaft 32 reversal this moment, thereby will drive and compress tightly slider 29 rebound, and when compressing tightly slider 29 rebound to be in the butt state with contact switch 27, motor 31 closed this moment, thereby initial condition is got back to the device, thereby has realized the automatic re-setting of device, can take out optical cable 17 to the external world afterwards.

The invention has the beneficial effects that: this device can carry out the self-defining to the cable of different specifications through pressure adjustment knob and set up its suitable pressure value, and cooperate hold-down spring simultaneously through the last friction roller that can move down to make the device realize compressing tightly the automation of optical cable with the pressure value that sets up in advance, saved artifical frequent adjusting pressure's trouble on the one hand, on the other hand has guaranteed that the optical cable receives the certain of pressure, has avoided the undersize of pressure to lead to skidding, perhaps the condition emergence of the too big damage optical cable of pressure.
