[0022] The utility model will be further explained in detail in combination with the drawings and through the embodiment, and the following embodiment is the explanation of the utility model, and the utility model is not limited to the following embodiment.

[0023] EMBODIMENT

[0024] Referring to Figures 1 to 10 , the unclogging machine flexible shaft convenient to replace and with length marks in the embodiment includes rear flexible shaft 1, connecting screw 2 and flexible shaft body 3, wherein the length of rear flexible shaft 1 is 20-50cm.

[0025] The rear end of rear flexible shaft 1 in the embodiment is provided with flexible shaft connecting ring 12, and rear flexible shaft 1 can be connected into the flexible shaft placer of unclogging machine body 4 through flexible shaft connecting ring 12, so as to install unclogging machine flexible shaft on unclogging machine body 4, and rear flexible shaft joint 11 is fixed on the front end of rear flexible shaft 1.

[0026] The rear end of flexible shaft body 3 in the embodiment is fixed with flexible shaft body joint 31, and the flexible shaft body joint 31 and rear flexible shaft joint 11 on rear flexible shaft 1 are fixed through connecting screw 2.

[0027] The rear flexible shaft joint 11 of the rear flexible shaft 1 in the embodiment is provided with a connecting groove, the wall surface on both sides of the connecting groove is provided with a screw hole in the form of a through hole, the flexible shaft body joint 31 of the flexible shaft body 3 is provided with a connecting protrusion, the connecting protrusion is provided with a screw hole in the form of a through hole; when the flexible shaft body joint 31 and the rear flexible shaft joint 11 are fixed by the connecting screw 2, the connecting protrusion in the flexible shaft body joint 31 is inserted into the connecting groove of the rear flexible shaft joint 11, the two screw holes in the connecting groove and the screw hole in the connecting protrusion are aligned, and the connecting screw 2 is fixed in the screw hole of the connecting groove, the screw hole of the connecting protrusion and the other screw hole of the connecting groove in sequence by screwing, that is, the connecting screw 2 passes through the screw hole of the connecting groove, the screw hole of the connecting protrusion and the other screw hole of the connecting groove in sequence.

[0028] In the actual application process of the dredging machine, the damaged part of the flexible shaft of the dredging machine is almost on the flexible shaft body 3, and the part of the flexible shaft of the dredging machine within 50 cm close to the dredging machine body 4 is almost not damaged, so when the flexible shaft of the dredging machine needs to be replaced due to damage, only the flexible shaft body 3 needs to be replaced by screwing the connecting screw 2, and the rear flexible shaft 1 does not need to be replaced, so the soft shaft placing device of the dredging machine body 4 does not need to be disassembled, which greatly facilitates the efficiency of replacing the damaged flexible shaft of the dredging machine and reduces the workload of replacing the flexible shaft of the dredging machine.

[0029] In the use of the flexible shaft of the dredging machine in the embodiment, the rear flexible shaft connecting ring 12 in the rear flexible shaft 1 is installed inside the soft shaft placing device of the dredging machine body 4, the rear flexible shaft joint 11 can extend to the mouth of the soft shaft placing device of the dredging machine body 4, at this time, the flexible shaft body joint 31 of the flexible shaft body 3 is connected with the rear flexible shaft joint 11, and the connecting screw 2 is used for connection and fixation, and the whole flexible shaft is put into the soft shaft placing device of the dredging machine body 4 to complete the installation and fixation of the flexible shaft. When replacing the flexible shaft, only the flexible shaft body 3 needs to be pulled out of the soft shaft placing device of the dredging machine body 4, and the connecting screw 2 needs to be unscrewed to remove the flexible shaft body 3, and the operation of replacing the flexible shaft can be completed by replacing the new flexible shaft body 3 and installing the connecting screw 2.

[0030] The outer surface of the flexible shaft body 3 in the embodiment can be provided with a length identifier, and the length identifier on the flexible shaft body 3 can be a number or a pattern.

[0031] The color or corrosion pattern can be sprayed or plated on the outer surface of the flexible shaft body 3 to retain various identification patterns on the outer surface of the flexible shaft body 3. For example, a narrow stripe is left at every 1-meter interval on the flexible shaft body 3, which is identification one A1; a wide stripe is left at every 5-meter interval, which is identification two A2; a double narrow stripe is left at every 10-meter interval, which is identification three A3; a very wide stripe can be left at the end of the flexible shaft body 3 to indicate that the flexible shaft body 3 is used up, and dredging should be stopped at this time.

[0032] The shape of the length mark on the soft shaft body 3 can be set according to actual conditions, such as color stripes, leaving a length mark on the outer surface of the soft shaft body 3 for indicating the length of the soft shaft body 3 that has been used. In actual use, the user can immediately know the actual length of the soft shaft body 3 after it is extended according to the length mark seen, reducing the unpredictability of operation.

[0033] In addition, it should be noted that the specific embodiments described in the specification, the shape of the zero, the components, the name taken, etc. can be different, and the above described in the specification is only an example of the structure of the utility model. Any equivalent changes or simple changes made according to the structure, features and principles described in the utility model patent concept are included in the protection scope of the utility model patent. The skilled in the art of the utility model can make various modifications or supplements or adopt similar ways to replace the specific embodiments described, as long as it does not deviate from the structure of the utility model or beyond the scope defined in the claims, which shall belong to the protection scope of the utility model.
