[0028] Please refer to Figures 1 to 6 The pipe cleaning machine in the figure is designed with a hand crank 1, a grip 2, a casing assembly 3, an outer guide tube 4, and a flexible shaft 5; the hand crank 1 is used to rotate the flexible shaft 5, the grip 2 is used to fix other components and transmit the transmission of the hand crank 1, the casing assembly 3 is used to store the hand crank 1 and the flexible shaft 5, the outer guide tube 4 is used to cover the flexible shaft 5, and the flexible shaft 5 is used for cleaning work; in actual applications, the above components can be further optimized or other components can be added.

[0029] The overall structure of the hand crank 1 in the figure is similar to that of the existing hand crank 1, and it is designed with a handle 11, a rocker 12, an output shaft 13, a steel ball 14, a spring 15, a quick-change sleeve 16 and other structures. The handle 11 adopts a cylindrical structure to facilitate the user's hand shaking, and its outer side has an irregular structure with multiple protrusions 111, which increases the friction of the hand holding the handle 11. The rocker 12 adopts a common Z-shaped structure as a whole, so that the handle 11 can drive the output shaft 13 to rotate when it is shaken. The output shaft 13 adopts a circular shaft structure as a whole, and a screw hole 61 structure is designed on the side facing the rocker 12, so that the output shaft 13 is fixed to the rocker 12 by screws, and the output shaft 13 is designed with a hexagonal regular hole 131 structure as shown in the figure in the direction facing the grip 2, so that it can be assembled with the regular part 23 at the corresponding position of the grip 2. In this way, when the hand crank 1 is inserted into the grip 2, the two can be assembled together, which is also convenient for mutual disassembly. In order to facilitate the mutual disassembly of the hand crank 1 and the grip 2, a steel ball 14, a spring 15, and a quick-change sleeve 16 can be designed at the end of the rocker 12 facing the grip 2, wherein the steel ball 14 is respectively configured with the annular slide groove corresponding to the regular portion 23 of the grip 2 and the output shaft 13 of the hand crank 1, and the spring 15 is sleeved in the quick-change sleeve 16 and sleeved on the outside of the output shaft 16, so as to imitate the existing steel ball 14 and the spring 15 that resets the quick-change sleeve 16 to achieve elastic disassembly and installation. In practical applications, the hand crank 1 can be optimized in detail or other designs can be added to make the hand crank 1 more adaptable.

[0030] The handle 2 in the figure adopts the structural design as shown in the figure. The handle 2 is sleeved on the outer guide tube 4, and one end thereof is kept assembled with the hand crank 1, and the other end is kept assembled with the housing assembly 3. The outer surface of the above-mentioned handle 2 is designed with a friction end 21 protruding outward, such as the dot-shaped and rectangular structures in the figure. In order to maintain a tight fit with the housing assembly 3, an annular groove 22 structure can be designed at the corresponding position, and the housing assembly 3 also maintains the structural design of the annular snap ring portion 31, so that the snap ring portion 31 is inserted into the groove 22 to fix the housing assembly 3 on the handle 2. In actual application, the design of other structures of the handle 2 can refer to the existing technology, and the outer side surface and the part assembled with the housing assembly 3 can be adjusted according to actual conditions.

[0031] The housing assembly 3 in the figure is formed by two housing parts assembled together so as to be sleeved on the outer conduit 4, such as the first housing 32 and the second housing 33 structure in the figure. In order to facilitate sleeved on the outer conduit 4, the first housing 32 and the second housing 33 are both designed with a semicircular groove 34 structure, so as to achieve a tight fit with the tube wall of the outer conduit 4. In order to fit the two housing parts together, each of them is designed with a screw hole 61 structure, so that the two housings can be installed on the outer conduit 4 by screwing through the screw hole 61. Specifically, as shown in the figure, the housing assembly 3 is designed with a first clamping portion 35, a second clamping portion 36, a first protective portion 37, a second protective portion 38, and a housing portion 39, wherein the first clamping portion 35 is used to clamp and fix the end position of the handle 11, the second clamping portion 36 is used to clamp and fix the rocker 12 to complete the storage of the hand crank 1, the first protective portion 37 is used to fix the part of the flexible shaft 5 close to the end position, that is, the circular tube portion 51, the second protective portion 38 is used to clamp and fix the end position of the flexible shaft 5, that is, the conical portion 52, so as to prevent the flexible shaft 5, that is, the flexible shaft head, from accidentally injuring people like the first protective portion 37, and increase safety protection, and the housing portion 39 is used to fix the above two clamping portions and two protective portions, and the above two clamping portions and two protective portions can adopt a structural design that is integrated with the housing portion 39. As shown in the figure, the interior of the housing portion 39 adopts a hollow design so as to fit with the outer conduit 4, and the outer wall of the housing portion 39 can support and fix other components. The first clamping portion 35 has a hollow structure and a notch, and the hollow cavity matches the outer diameter of the handle 11 of the hand crank 1, so that the handle 11 of the hand crank 1 can be inserted into the first clamping portion 35. The second clamping portion 36 also has a hollow structure and a notch, and the hollow cavity also matches the outer diameter of the rocker 12, so that the rocker 12 of the hand crank 1 can be inserted into the second clamping portion 36 by pressing. The first protective portion 37 is designed with a staggered arrangement of three protrusions 371 as shown in the figure, and each protrusion 371 is also hollow inside and can be assembled with the circular tube 51 of the flexible shaft 5. The second protective portion 38 also adopts a hollow and notch design, so that the end position of the flexible shaft 5 can be arranged inside the second protective portion 38. In practical applications, the housing assembly 3 can be re-optimized, and the details or quantity of its components can be adjusted as needed.

[0032] The outer catheter 4 in the figure is a conventional existing component, and its interior is hollow, so that one end of the flexible shaft 5 can be arranged in the outer catheter 4.

[0033] The flexible shaft 5 in the figure is also an existing component, which adopts a similar design to the bellows.

[0034] Through the above design, if it is necessary to rotate the flexible shaft 5 to make it work, assemble the hand crank and the handle 2 together, and then shake the hand crank. If it is necessary to store the entire pipe cleaning machine, the hand crank can be removed from the handle 2 and snapped into the first snap-fitting portion 35 and the second snap-fitting portion 36. At the same time, the flexible shaft 5 can be arranged at the first protective portion 37 and the second protective portion 38. In this way, the entire pipe cleaning machine can be well stored to avoid the loss of components.
