DETAILED DESCRIPTION

[0027] Please refer to Figures 1 to 4 The pipe dredging machine in the figure is designed with an outer conduit 1, a handle 2, and a crank assembly 3, and the dredging pipe is omitted in the figure; the outer conduit 1 and the handle 2 can use existing components or be adaptively fine-tuned according to existing components, and the outer conduit 1 and the crank assembly 3 are respectively installed and arranged on both sides of the handle 2. The mutual assembly of the outer conduit 1, the handle 2, and the crank assembly 3 can refer to the existing technology. The crank assembly 3 is the main innovation of this case, so the crank assembly 3 is described in detail below.

[0028] The crank assembly 3 in the figure is designed with a rocker 31, a handle cover 33, a handle tube 32, and a handle seat 34; the rocker 31 is used to be assembled with the handle 2, so that when it is rotated, it can drive the dredging pipe in the handle 2 to rotate to perform pipeline dredging work, and the handle cover 33, the handle tube 32, and the handle seat 34 are used to support and fix the rocker 31, which is convenient for an external electric drill. The rocker 31 in the figure is composed of three straight rods 311 with a cylindrical main structure that are hinged to each other and assembled into a straight state structure, that is, as shown in the figure, the two straight rods 311 are hinged to each other in the form of a concave-convex plug-in 313 to realize the linkage between the two straight rods 311. The straight rod 311 at the end position and the head end position in the figure is movably fixedly assembled with the handle 2 toward the end of the handle 2, and the straight rod 311 is movably assembled with the handle cover 33 at the same time. The straight rod 311 at the middle position is inside the handle tube 32, and the straight rod 311 at the other end, i.e., the end position, is movably assembled with the handle seat 34. At the same time, a connecting rod 312 is arranged on the straight rod 311 at the tail end position, and the connecting rod 312 is a hexagonal regular column structure. At this time, the connecting rod 312 is arranged outward relative to the handle seat 34 as a whole, which is convenient for the cooperation of an external electric drill. The connecting rod 312 can be designed to be an integral structure with the straight rod 311, or a separate structure, as long as the straight rod 311 is kept in linkage when the connecting rod 312 rotates. In order to facilitate the mutual configuration of the straight rod 311 and the handle cover 33, the handle tube 32, and the handle seat 34, the handle cover 33 and the handle seat 34 are designed with perforations 35 at corresponding positions, and the handle tube 32 is kept hollow inside. The handle tube 32 in the figure is a hollow round tube structure, and the handle cover 33 is conveniently installed on the side facing the grip 2, and the handle seat 34 is conveniently installed on the other opposite end. Through such a configuration, the straight rod 311 can keep matching with the handle cover 33 and the handle seat 34. In order to facilitate the mutual assembly of the handle cover 33 and the handle tube 32, two symmetrically arranged positioning grooves 331 can be designed on the handle cover 33, and two symmetrically arranged positioning blocks 321 structures are also designed at the corresponding positions on the top of the handle tube 32, so that the positioning grooves 331 and the positioning blocks 321 cooperate with each other to realize the mutual assembly of the handle cover 33 and the handle tube 32. In order to facilitate the stable support of the straight rod 311 in the handle tube 32, a support column 322 structure can be designed at a corresponding position inside the handle tube 32. The support column 322 is hollow inside to form a perforation 35 structure to facilitate the insertion of the straight rod 311. At the same time, four evenly arranged support bars 3221 structures are designed on the outside of the support column 322, so that a stable fixed relationship with the inner wall shape of the handle tube 32 can be maintained.In addition to the structural design of the support column 322, the handle cover 33 can also be extended in the direction of the handle tube 32, that is, a first extension portion 332 is extended to increase the degree of cooperation with the straight rod 311, thereby preventing the shaking of the straight rod 311 and increasing the overall strength of the handle cover 33. The first extension portion 332 also has a perforation 35 structure inside to facilitate the insertion of the straight rod 311. At the same time, the handle seat 34 is also extended in the direction of the handle tube 32, that is, a second extension portion 341 is extended to increase the degree of cooperation with the straight rod 311 and increase the overall strength of the handle cover 33, or a bearing component is installed inside the second extension portion 341, so that the straight rod 311 directly inserts the bearing hole of the bearing. In actual applications, the number, shape and cooperation relationship of the above components with other components can be adjusted according to actual conditions, such as the number of straight rods 311, the hinge structure between adjacent straight rods 311, etc. can be optimized or additional components can be added.

[0029] Please refer to Figures 5 to 8 , the pipe cleaning machine in the figure and Figure 1 The difference between the pipe dredging machine and the pipe dredging machine is that the rocker 31 is designed as a bent state structure, that is, a Z-shaped structure, so that the straight rod 311 at the end of the rocker 31 remains assembled with the handle cover 33 alone, and the connecting rod 312 is entirely in the handle tube 32. In order to fix and support the straight rod 311 at the end, a circular groove 3111 structure can be designed for the straight rod 311 close to the connecting rod 312, so that a transversely fixed fixing chuck 36 is arranged on the groove 3111, and the chuck 36 is designed as a disc or disk structure. In this way, a circular wall 361 structure is formed on the outside of the chuck 36 to keep it fixed with the inner wall of the handle tube 32, and at the same time, a mutually spaced spring sheet 362 structure is designed on the inside of the chuck 36 so as to form a clamping structure with the groove 3111 of the straight rod 311.
