DETAILED DESCRIPTION

[0028] To describe the technical contents, structural features, purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, rather than all the embodiments. In the following description, for the purpose of explanation, a large number of specific details are set forth in order to provide a thorough understanding of various exemplary embodiments or implementations of the application. However, various exemplary embodiments can also be implemented without these specific details or in one or more equivalent arrangements. In addition, various exemplary embodiments can be different, but not necessarily exclusive. For example, the specific shape, structure and characteristics of an exemplary embodiment can be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0029] In addition, in this application, spatial relative terms such as "under", "below", "lower", "above", "upper", "on", "higher", "side" (for example, as in "side wall") are used to describe the relationship between one element and another (other) element as shown in the drawings. The spatial relative terms are intended to include different orientations of the device in use, operation and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, the element described as "below" or "under" the other element or feature will then be positioned "above" the other element or feature. Therefore, the exemplary term "below" can include both upward and downward orientations. In addition, the device can be positioned otherwise (for example, rotated 90 degrees or at other orientations), so that the spatial relative descriptions used herein are interpreted accordingly.

[0030] In this application, the term "downstream" means, in relation to the direction of movement of the core wire, that one object is downstream of another. For example, in "heating device located downstream of the grooved roller," "downstream" means, in relation to the direction of movement of the core wire, that the heating device is downstream of the grooved roller.

[0031] like Figure 1 The diagram shows a side view of the spiral mesh 2. The spiral mesh 2 is formed by the interlocking and overlapping of several left-handed spiral rings 201 and right-handed spiral rings 201' made of polymer material with different rotation directions. An overlapping region 202 is defined between adjacent left-handed and right-handed spiral rings 201 and 201'. The spiral mesh 2 is formed by threading pins 205 through the overlapping region 202. The interior of the spiral 2 also defines a non-overlapping region of the spiral rings adjacent to the overlapping region 202, called a filler region 203. When it is necessary to reduce the air permeability of the spiral mesh 2, several filler core wires 204 can be filled into the filler region 203. The cross-section of the filler core wires 204 is not limited to circular, elliptical, or rectangular shapes.

The guide rod 1021 is a replaceable element; different types of guide rods 1021 have guide eyes 10211 with different structures (such as different shapes and sizes) to accommodate different types of core wires. In this example, the connector 1022 is an upward-facing insertion hole into which the lower end of the guide rod 1021 can be inserted in a specific direction. In fact, the distribution pattern of the insertion hole orientation of the connector 1022 is determined by the orientation of the filling area 203.

The fine-tuning movable block 406 is fixedly connected to the second end 1024 of the scissor mechanism 102. The user can control the rapid extension and retraction of the coarse adjustment movable block 404 in the left and right directions by rotating the coarse adjustment handle 403 to adjust the approximate distance between adjacent guide rods 1021. By controlling the fine adjustment wheel 407 of the fine adjustment mechanism on the coarse adjustment movable block 404, the user can control the fine adjustment movable block 406 and the second end 1024 of the scissor mechanism 102 connected to the fine adjustment movable block 406 to adjust the precise distance between adjacent guide rods 1021. After the adjustment is in place, the coarse adjustment screw 401 and / or the fine adjustment screw 405 can be locked by the screw rotation locking mechanism.
