DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the technical solutions of the present disclosure clearer, the present disclosure is described in detail below with reference to FIG. 1 and FIG. 2. It should be understood that the specific implementations described herein are merely intended to explain the present disclosure, rather than to limit the protection scope of the present disclosure.

[0023] The present disclosure provides a telescopic adapter device for a dredging machine, including protective cover 10 at an exit of flexible shaft 12 of dredging machine 11, connector 8 detachably connected to the protective cover 10, flexible shaft conduit 7 with an inner end fixed in an inner hole of the connector 8, and sliding conduit 2 sleeved on an outer wall of the flexible shaft conduit 7. The sliding conduit 2 includes an inner end provided with clamping joint 2-1 for clamping the flexible shaft conduit 7, and an outer end provided with bending portion 2-2. Rubber jacket 1 is sleeved on an outer wall of the bending portion 2-2.

[0024] Preferably, protective cover through hole 10-3 for allowing the flexible shaft 12 to pass through is formed in a middle of the protective cover 10. Outer end of the protective cover 10 is provided with turnbuckle B10-1 clamped with turnbuckle A8-2 of the connector 8. The protective cover 10 and the exit of the flexible shaft 12 are connected through a bolt, or connected through a corresponding turnbuckle, or connected by bonding, or connected by welding. The clamping joint 2-1 includes clamping jacket 2-1-3, triggering buckle 2-1-4, pin 2-1-5, and an elastic locking member that is preferably rubber pad 2-1-6 with an arc at an inner end. The inner end of the sliding conduit 2 is fixed in an inner hole of the clamping jacket 2-1-3. The pin 2-1-5 is provided on support lugs at two ends of the clamping jacket 2-1-3. Cam 2-1-4-1 at one end of a triggering handle of the triggering buckle 2-1-4 is hinged to the pin 2-1-5. When the triggering handle is pressed toward the clamping jacket 2-1-3, the triggering handle drives the cam 2-1-4-1 to rotate around the pin 2-1-5, the cam 2-1-4-1 squeezes the elastic locking member 2-1-6, and the elastic locking member 2-1-6 radially abuts against the outer wall of the flexible shaft conduit 7 from the clamping jacket 2-1-3 and a through hole of the sliding conduit 2, thereby clamping the flexible shaft conduit 7. The connector 8 includes inner barrel 8-0, and outer ring 8-3 provided at a periphery of an inner end of the inner barrel 8-0. The turnbuckle A8-2 is positioned at an inner end of the outer ring 8-3. The inner barrel 8-0 includes the inner end provided with connector positioning bump 8-1 matched with flexible shaft conduit positioning groove 7-2, and an outer end provided with threaded hole 8-4 corresponding to flexible shaft conduit fixing hole 7-1. A front end of bolt 9 extends to the flexible shaft conduit fixing hole 7-1 through the threaded hole 8-4. The protective cover 10 is clamped with a corresponding turnbuckle at the exit of the flexible shaft 12 of the dredging machine 11 through turnbuckle 10-2 at an inner end of the protective cover. The elastic locking member 2-1-6 is a rubber pad with an arc surface at an inner end. Both the sliding conduit 2 and the flexible shaft conduit 7 are made of a stainless steel material.

[0025] By providing the telescopic adapter device on the dredging machine, the front rubber jacket 1 can protect a glazed surface of a toilet well. With the bending portion 2-2 of the sliding conduit 2, the flexible shaft has a better turning capacity and is not knotted. With the telescopic function, the telescopic adapter device can be optimally adjusted in length and angle for users with different heights and operation habits, improves a pipe dredging efficiency and makes the operators more comfortable. When the telescopic adapter device is not used, the sliding conduit 2 and the flexible shaft conduit 7 are detached conveniently to greatly shorten the overall length for the convenience of storage.
