The slider 634 is driven by the cam 637 and cooperates with the elastic force of the elastic member to slide back and forth in the slide groove 614, thereby opening or closing the swing arm 62.
The elastic member may be a spring 635, where the spring 635 is disposed in the chute 614, and one end of the spring 635 is fixedly connected to an inner end surface of the chute 614, and the other end is connected to an inner end surface of the slider 634, and the spring 635 is always in a compressed state, so that the slider 634 has a tendency to slide horizontally out of the chute 614.
Referring primarily to fig. 1 and 4 and 5, the opening and closing of the swing arm 62 is accomplished by the magnetic assembly 636 described above. The magnetic assembly 636 includes a first magnetic body 6361, a second magnetic body 6362, and a third magnetic body 6363, where the first magnetic body 6361, the second magnetic body 6362, and the third magnetic body 6363 are all permanent magnets 91, and the specific shape may be configured into a magnetic column, a magnetic sheet, or the like. The first magnetic body 6361 is mounted on the inner surface of the swing arm 62, and the surface of the first magnetic body 6361 is flush with the inner wall surface of the swing arm 62; the second magnetic attraction body 6362 and the third magnetic attraction body 6363 are both installed on the upper surface of the slider 634, the second magnetic attraction body 6362 and the third magnetic attraction body 6363 are arranged from outside to inside along the sliding direction of the slider 634, the first magnetic attraction body 6361 and the second magnetic attraction body 6362 are different-name magnetic attraction bodies, and the first magnetic attraction body 6361 and the third magnetic attraction body 6363 are same-name magnetic attraction bodies.
When the gland 3 turns downwards to cover, the crown gear 631 rotates, the cam 637 rotates along with the crown gear 631, the linkage sliding block 634 moves towards the inside of the sliding groove 614, and the first magnetic attraction body 6361 and the second magnetic attraction body 6362 are opposite, so that the swing arm 62 is attracted by magnetic force to turn downwards to cover; when the gland 3 is turned upwards and opened, the crown gear 631 reversely rotates, the cam 637 reversely rotates along with the crown gear 631, the linkage slider 634 reversely moves, and the first magnetic body 6361 and the third magnetic body 6363 face each other, so that the swing arm 62 is repelled by magnetic attraction to be turned upwards and opened.
A cam 637 is fixedly mounted on the outer end surface of the crown gear 631, and the cam 637 surface is always in line contact with the outer end surface of the slider 634, thereby driving the slider 634 to slide. In the actual optical fiber cutting process, when the optical fiber is cut, the flip cover 9 needs to be opened, and the driving gear 633 is synchronously driven to rotate in the opening process of the flip cover 9, so that the broken optical fibers formed after cutting are transmitted into the material receiving port 612, at this time, the swing arm 62 should not be opened immediately, and accidents such as broken optical fibers falling caused by the fact that the broken optical fibers do not completely enter the material receiving port 612 and the swing arm 62 is opened are avoided. For this reason, the structure of the cam 637 needs to be designed to a certain extent.
Referring primarily to fig. 2, 6 and 7, the cam 637 has a first working surface 6371 and a second working surface 6372, the first working surface 6371 being a part of the cam surface of the side of the cam 637 facing the slider 634, the first working surface 6371 having a start point 6373 and an extreme point 6374, where the start point 6373 refers to a point (optionally a midpoint of line contact) where the first working surface 6371 contacts the outer end surface of the slider 634 when the gland 3 is fully opened, and the extreme point 6374 refers to a point where the first working surface 6371 of the cam 637 drives the slider 634 to slide inward to an extreme position in contact with the outer end surface of the slider 634 during the capping of the gland 3.
The radius of rotation of the first working surface 6371 (the radius of rotation refers to the distance from the point of the cam surface to the rotation center of the rotating cam) gradually increases from the start point 6373 to the limit point 6374, so that when the capping action of the capping 3 starts, the first working surface 6371 drives the slider 634 to move inwards, and when the capping 3 starts to turn downwards and does not cap, the swing arm 62 is driven to cap, so as to press the optical fiber; conversely, during the opening of the gland 3, the swing arm 62 does not act, and when sliding from the limit point 6374 to the initial point, the swing arm 62 opens, in which operation the active guide roller 7 is sufficient to transfer the crushed fibers into the mouth 612.
The second working surface 6372 is a partial cam surface of the cam 637 on the side facing away from the slider 634, the second working surface 6372 continuing the first working surface 6371 from a limit point 6374 of the first working surface 6371, the radius of rotation of the second working surface 6372 being smaller than the radius of rotation of the first working surface 6371 at the limit point 6374.
When the gland 3 is completely covered, the outer end surface of the slider 634 is in line contact with the second working surface 6372, so that accidental movement of the cam 637 in the cutting process can be avoided, and the stability of optical fiber cutting is improved.

then, the optical fiber to be cut is positioned and installed on the optical fiber guiding part 2, after positioning and installation, the gland 3 is slowly turned downwards, at the moment, the gland 3 drives the first transition gear 6321 and the second transition gear 6322 to rotate, so as to drive the crown gear 631 to rotate, the crown gear 631 drives the first working surface 6371 of the cam 637 to drive the sliding block 634 to slide in the sliding groove 614, the first magnetic attraction body 6361 is opposite to the second magnetic attraction body, the swing arm 62 turns downwards to cover the material receiving opening 612, and synchronously, the crown gear 631 drives the driving gear 633 to rotate, so as to drive the driving guiding roller 7 to rotate;
referring to fig. 5 and 7, after the gland 3 is completely covered, the sliding cutting assembly 4 is pushed to complete the structural cutting of the fiber incision;
it should be noted that, when the sliding cutting assembly 4 is cut, the sliding cutting assembly 4 is locked to avoid damage to the optical fiber caused by the restoration of the sliding cutting assembly 4, and the present utility model omits this step, and the detailed description of the locking assembly is omitted, and the prior art in the background art already fully discloses the locking assembly.
Finally, the gland 3 is slowly turned upwards to open, at this time, the crown gear 631 reversely rotates to drive the sliding block 634 to move outwards of the sliding groove 614, but the swing arm 62 is not opened, and synchronously, the crown gear 631 drives the driving guide roller 7 to reversely rotate, so that the broken optical fibers are transferred into the accommodating cavity 611 in cooperation with the driven guide roller 71;
