When the first end of the extension plate 501 is in frictional contact with the outer circumferential surface of the first steering roller 1, the first steering roller 1 applies a force non-parallel to the top surface of the extension plate 501 to the extension plate 501, and the guide mechanism limits the extension plate 501, the guide mechanism is likely to malfunction due to the frictional force between the first end of the extension plate 501 and the outer circumferential surface of the first steering roller 1. Thus, the end surface of the first end of the extension plate 501 is provided with at least one sliding aid structure, which may contact the outer circumferential surface of the first steering roller 1, and the end surface of the first end of the extension plate 501 does not contact the outer circumferential surface of the first steering roller 1.
The structure of helping sliding is the ball, and the terminal surface of extension plate 501 first end is opened has a plurality of mounting grooves that hold the ball, and a plurality of balls are rotatable to be set up at the terminal surface of extension plate 501 first end, and the ball is with first turning roll 1 point contact, and the ball can roll, be rolling friction between ball and the first turning roll 1 outer rampart, and frictional force reduces by a wide margin, and extension plate 501's removal is more smooth, and guiding mechanism's fault rate reduces.
Referring to fig. 3, in the present embodiment, the slipping-assisting structure may also be a slipping-assisting roller 505, the slipping-assisting roller 505 may be rotatably disposed on the extension plate 501, an axis of the slipping-assisting roller 505 is parallel to an axis of the first steering roller 1, an outer circumferential surface of the slipping-assisting roller may contact an outer circumferential surface of the first steering roller 1, and rolling friction is formed between the slipping-assisting roller and the first steering roller 1, which is beneficial to movement of the extension plate 501. The two sliding rollers can be arranged to improve the stability, and can be fixedly arranged on the two opposite sides of the first end of the extension plate 501, so that the sliding rollers are more convenient to install and easier to overhaul and replace compared with balls.
Referring to fig. 3, in the present embodiment, the extension plate 501 is a plate, and the extension plate 501 may be a grid plate to reduce the weight of the extension plate 501. The length of the extension plate 501 is not greater than that of the first steering roller 1, and particularly in the case where the slip-assist structure is the slip-assist roller wheel 505, the length of the extension plate 501 is smaller than that of the first steering roller 1 so that the slip-assist roller wheel can contact the outer circumferential wall of the first steering roller 1.
When the spring is in a natural state, that is, when the extension plate 501 is not in contact with the first steering roller 1, the width of the extension plate 501 exceeding the threading guide 4 is less than half of the width of the extension plate 501, so as to ensure the stability of the extension plate 501 during movement, and further, when the spring is in a natural state, the width of the extension plate 501 exceeding the threading guide 4 is one third of the width of the extension plate 501, so that the contact area of the extension plate 501 and the threading guide 4 is increased, and the stability of the auxiliary device 5 during operation is further ensured.
It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
