[0031] A ball head 38 is provided on the limiting member 8, and a ball head groove 39 cooperating with the ball head 38 is provided on the limiting member 7, so that the limiting member 7 needs to be subjected to external force to make the ball head 38 disengage from the ball head groove 39, thereby ensuring that the position of the limiting member 7 will not move.

[0032] The limiting member 8 is provided with a rotating hole 40 that cooperates with the hinge shaft 24. The reset member 21 is arranged in the rotating hole 40. The limiting member 8 is provided with an extension body 41, which is composed of an extension section 42 and an arc section 43. The arc section 43 is arranged upward.

[0033] The limiting member 8 is provided with a through opening 75 for avoiding the first limiting section 55 .

[0034] An elastic sleeve 11 is provided on the extension body 41, a mounting groove 44 for accommodating the extension body 41 is provided in the middle of the elastic sleeve 11, and a plurality of elastic protrusions 45 are provided on the elastic sleeve 11.

The sliding body 50 is connected to the triangular body 49 through a connecting body 51, and the connecting body 51 is arranged in the sliding groove 26. The triangular body 49 is provided with a limiting end 52 that cooperates with the limiting opening 48. The upper end of the triangular body 49 is provided with an inclined surface 53, and the lower end is provided with a blocking surface 54.

[0038] When the limit member 8 needs to be reset, an unlocking member 72 is required. A first unlocking inclined surface 73 is provided on the unlocking member 72, and a second unlocking inclined surface 74 is provided on the sliding body 50. The unlocking member 72 is arranged at the upper end of the retaining assembly 3. A cylinder is used to push the unlocking member 72 downward, so that the first unlocking inclined surface 73 pushes the sliding body 50 to compress the spring 10, so that the limit end 52 disengages from the limit opening 48.

[0039] The limiting end 52 can cure the rotation of the limiting member 8 in the limiting port 48 , pushing the inclined surface 53 through the limiting teeth 34 , so that the retaining member 9 is pushed to slide in the sliding groove 26 , and compress the spring 10 .

The limit member 8 is provided with a first through hole 58 for accommodating the first limit segment 55, and the retaining seat 19 is provided with a second through hole 59 for accommodating the second limit segment 56.

[0041] Since the first limiting segment 55 is mounted on the limiting member 8 and can rotate with the limiting member 8, while the second limiting segment 56 is mounted on the retaining seat 19 and does not rotate with the limiting member 8, when the limiting member 8 drives the first limiting segment 55 to rotate, the spiral segment 57 can be subjected to force to generate a certain elastic force, thereby storing a certain elastic potential energy. When the limiting end 52 no longer restricts the limiting member 8, the limiting member 8 will be reset under the elastic potential energy stored in the spiral segment 57.

[0042] A symmetrical spring 10 is provided between the barrier member 20 and the retaining member 9 . The retaining member 9 pushes the retaining member 9 close to the limiting member 8 under the elastic force of the spring 10 , limiting the angle of rotation of the limiting member 8 .

[0043] The blocking member 20 consists of a vertical section 60 and transverse sections 61 symmetrically arranged at both ends of the vertical section 60. A notch 62 is formed in the middle of the transverse section 61. A symmetrically arranged locking body 63 is provided on the vertical section 60.

The sliding groove 26 is provided with a notch 69 that matches the locking body 63, a wall surface 70 that matches the first guide slope 66 is provided in the notch 69, and a second guide slope 71 that matches the first guide slope 66 is provided at the notch of the sliding groove 26.

[0045] When the barrier member 20 is installed, the first guide inclined surface 66 is guided through the second guide inclined surface 71 , so that its locking body 63 enters into the sliding groove 26 , and then enters the limit in the recess 69 .

[0046] The fiber optic housing is clamped between the two holding components 3 by the clamping assembly 15 , and then driven by the conveyor belt 2 , so that the holding component 3 moves so that the fiber optic housing enters the receiving area 4 .
