1 to 4 show a pipeline cleaner 100 including a spring wire control device 10 of the present invention. The pipeline cleaner 100 includes a reel 12, a support tube 14 provided at the front end of the reel 12, and the reel A spring wire 50 in the barrel 12 extends through the support tube 14. A crank arm 16 is provided on the rear side of the reel 12, and a grip 18 is provided at the lower portion of the support tube 14 to provide a user's hand grip.

The spring wire control device 10 is installed at the front end 141 of the support tube 14 and includes a cylinder 19, a control member 40 and a dial lever 41. In this embodiment, the barrel 19 is composed of the upper body 20 and the lower body 30 combined. In another embodiment, the barrel 19 is integrated (see FIG. 7). The upper body 20 is a shell with a semi-circular cross section and the outer surface 201 of the upper body 20 is provided with a protruding joint The barrel 21 has a perforation 26 inside the coupling barrel 21 and a screw thread 24 outside the coupling barrel 21 to provide an upper cover 25 for locking. The coupling barrel 21 is provided with one or two slotted holes. In this embodiment, the coupling barrel 21 is provided with a first slotted hole 22 and a second slotted hole 23 which are opposite to each other along the circumferential direction of the coupling barrel 21. The slots 22 and 23 communicate with the perforation 26. The lower body 30 is a housing with a semi-circular cross-section and the lower body 30 is provided with a plurality of connecting holes 33, which can be combined with the upper body 20 through a connecting hole 33 of the lower body 30 through a connecting member (not shown) such as a screw To constitute the cylinder 19. A first roller 31 and a second roller 32 are provided inside the lower body 30.

The control member 40 is rotatably received in the through hole 26 of the coupling barrel 21. In this embodiment, the control member 40 is a cylinder, and a gasket 42 and a disk-shaped gasket 421 are provided in the coupling cylinder 21 between the upper end of the control member 40 and the upper cover 25, so that the upper cover 25 is compressible The gasket 42 and the dish-shaped gasket 421 are used to adjust the strength of the gasket 42 against the control member 40.

After the spring wire control device 10 of the present invention is installed at the front end 141 of the support tube 14, the first and second rollers 31, 32 and the third roller 43 installed in the upper body 20 are generally in a triangular configuration, and The spring wire 50 extends through the three rollers 31, 32, 43 (see FIG. 5). The operation of the upper cover 25 presses the control member 40 so that the three rollers 31, 32, 43 can clamp the spring wire 50 to control the spring wire 50 to move forward or backward.

For the rest, please cooperate with FIG. 5 and FIG. 6 and paragraph 0012 of this specification; when the user operates the pipeline clearer 100, the user holds the grip 18 in one hand and the crank arm 16 rotates in the other hand, so that the drum 31, The spring wires 50 clamped by 32 and 43 can be advanced or retracted. As shown in FIG. 2, when the shift lever 41 is moved to the right end of the first slot 22 (see the forward arrow 27 of FIG. 2 ), the control member 40 will rotate to drive the third roller 43 to the orientation of FIG. 5, and The spring 50 is controlled to advance. On the other hand, when the shift lever 41 is moved to the left end of the first slot 22 (not shown, see the backward arrow 28 in FIG. 2), the third roller 43 will be driven by the control member 40 to the orientation of FIG. 6, and The control spring 50 is retracted.

By changing the spatial position of the third roller 43 relative to the first and second rollers 31, 32 to control the advance or retreat of the spring wire 50, although it is a conventional technique, however, the present invention Compared with the prior art, the disclosed spring wire control device 10 not only has a simpler structure, but also has the advantage of convenient operation. Specifically, when the user wants to control the spring wire 50 to move forward or backward, it can be achieved by using the hand holding the grip 18 to move the lever 41 to shift. Therefore, in the process of turning the lever 41, there is no need to The operation of the crank arm 16 is suspended or is operated with one hand. Especially when the pipeline is too blocked or the spring wire 50 is stuck in the pipeline and the spring wire 50 needs to be reciprocated forward and backward for a period of time, the user will be able to easily toggle the lever 41 with his finger to achieve a continuous spring Line 50 is alternately carried forward and backward.

7 and 8 show a spring wire control device 10 according to a second embodiment of the present invention, wherein components similar to those in the above-described first embodiment will be denoted by the same reference numerals. The cylinder 19 is made in one piece, the first roller 31 and the second roller 32 are arranged at the lower part of the cylinder 19 (corresponding to the lower body 30 of FIG. 1), and the control member 40 and the third roller 43 are arranged at the upper part of the cylinder 19 (corresponding diagram) 1) The upper body 20), the coupling cylinder 21 protrudes upward from the upper part of the cylinder body 19, the coupling cylinder 21 has a perforation 26 inside, and an upper cover 25 is provided at the upper end of the coupling cylinder 21. A spring 45 is provided in the coupling cylinder 21 between the upper end of the control member 40 and the upper cover 25 to adjust the force against the control member 40, and the coupling cylinder 21 is provided with a first slot 22 opposite to the surrounding direction of the coupling cylinder 21 With the second slot 23. In this embodiment, the front end 141 of the support tube 14 has an enlarged outer diameter to accommodate the cylindrical body 19, and an upper portion of the front end 141 is provided with a notch 142 to provide a cover 143 for closing, defining the sides of the notch 142 respectively A clamping slot 144 is provided to provide the flange 145 on both sides of the cover 143 to join.
