DETAILED DESCRIPTION OF THE EMBODIMENTS

(5) The principles and features of the present disclosure are described below in conjunction with the accompanying drawings, and the examples provided are only used to explain the present disclosure, not to limit the scope of the present disclosure.

(6) In the description of the present disclosure, it should be noted that the orientations or positional relationships indicated by the terms center, upper, lower, left, right, vertical, horizontal, inner, outer, clockwise and counterclockwise are based on the orientations or positional relationships shown in the drawings, which are only for the convenience of describing the present disclosure and simplifying the description, instead of indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.

(7) As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, a position-adjustable spool return-stop device includes a first sleeve 1, a second sleeve 2, and a wire saddle 3, where the wire saddle 3 has a cylindrical front end and a cone-shaped rear end; a through hole 31, through which a wire body can pass, is reserved in a middle of the wire saddle 3; a plurality of grooves 32 are provided at the rear end of the wire saddle 3, which divide the rear end of the wire saddle 3 into multiple petal bodies 3a; the first sleeve 1 and the second sleeve 2 are sequentially sleeved outside the wire saddle 3 from front to back, the first sleeve 1 and the wire saddle 3 are assembled with threads, and the second sleeve 2 is internally provided with a bundling hole 21; the inner diameter of the bundling hole 21 gradually increases from front to back, and the wire saddle 3 can move forward and backward along the bundling hole 21; and the wire saddle 3 cannot rotate relative to the second sleeve 2.

(8) When the position of the return-stop device on a wire/pipe needs to be adjusted, the first sleeve 1 is rotated, and the rear end of the wire saddle 3 is driven to move backward in the bundling hole 21 through the thread fit between the first sleeve 1 and the wire saddle 3, so that all the petal bodies 3a are enabled to open outward and thus increase the inner diameter of a rear end of the through hole 31, which allows the wire saddle 3 to loosen the wire/pipe, then the return-stop device is enabled to move on the wire/pipe, and the position of the return-stop device can be adjusted accordingly; and

(9) after the return-stop device moves to the corresponding position, the first sleeve 1 is reversely rotated, and the rear end of the wire saddle 3 is driven to move forward in the bundling hole 21 through the thread fit between the first sleeve 1 and the wire saddle 3, so that all the petal bodies 3a are enabled to move towards the center and thus decrease the inner diameter of the rear end of the through hole 31, which allows the wire saddle 3 to be locked to the wire/pipe.

(10) Preferably, anti-skid stripes 4 are provided on outer sides of the first sleeve 1 and the second sleeve 2.

(11) The fitting diameter of the return-stop device is related to the inner diameter of the through hole 31, the maximum and minimum inner diameters of the bundling hole 21, and the maximum and minimum opening degrees of the petal bodies 3a.

(14) Preferably, the protruding portion 22 is cylindrical, and the limiting protrusion 23 is annular.

(15) Preferably, the cross-sectional shape of the limiting protrusion 23 is a triangle-like shape.

In this embodiment, the first half sleeve 1a is fixedly connected to the second half sleeve 1b by screws.

Embodiment 2

(17) This embodiment has an improvement in the threaded structure of the wire saddle 3.

(18) As shown in FIG. 2 and FIG. 3, an external thread 33 is formed at a front end of the outer side of the wire saddle 3, a plurality of strip-shaped threads 34 are formed in a middle of the outer side of the wire saddle 3, the plurality of strip-shaped threads 34 are distributed on the outer side of the wire saddle 3 in the circumferential direction, the strip-shaped threads 34 are formed axially, and the strip-shaped threads 34 are connected to the external thread 33; the thread parameters of the strip-shaped threads 34 are the same as those of the external thread 33; there are the four strip-shaped threads 34, which are evenly distributed on the outer side of the wire saddle 3;

(19) the first sleeve 1 is internally provided with an internal thread 12, and the internal thread 12 is matched with the external thread 33 and the strip-shaped threads 34; and
