Abstract

A drain cleaner includes a shank, a clearing member connected with the shank, a support pipe allowing passage of the clearing member, a handgrip mounted on the support pipe, and a mounting sleeve mounted on the support pipe and connected with the handgrip. The support pipe has an upper end provided with a slit and a lower end provided with an arcuate portion and an extension. The handgrip is located outside of the support pipe and is provided with a slit. The mounting sleeve is located outside of the support pipe and is provided with a slit. The slit of the mounting sleeve is connected between the slit of the support pipe and the slit of the handgrip.

Claims

exact text as granted — not AI-modified
1 . A drain cleaner comprising:
 a shank;   a clearing member connected with the shank;   a support pipe allowing passage of the clearing member;   a handgrip mounted on the support pipe; and   a mounting sleeve mounted on the support pipe and connected with the handgrip;   wherein:   the clearing member extends through an interior of the support pipe;   the support pipe has an upper end provided with a slit which extends longitudinally;   the slit of the support pipe has a width slightly greater than an outer diameter of the clearing member;   the support pipe has a lower end provided with an arcuate portion and an extension;   the arcuate portion of the support pipe is opened upward;   the extension of the support pipe extends upward in an oblique manner;   the handgrip is located outside of the support pipe and is provided with a slit which extends longitudinally;   the slit of the handgrip has a width slightly greater than the outer diameter of the clearing member;   the handgrip has a lower end provided with an external thread;   the mounting sleeve is located outside of the support pipe and is provided with a slit which extends longitudinally;   the slit of the mounting sleeve has a width slightly greater than the outer diameter of the clearing member;   the mounting sleeve has an upper end provided with an internal thread screwed onto the external thread of the handgrip; and   the slit of the mounting sleeve is connected between the slit of the support pipe and the slit of the handgrip.   
     
     
         2 . The drain cleaner of  claim 1 , wherein:
 the shank has a first end provided with a shaft hole for mounting the clearing member and a second end provided with a driving portion;   the first end of the shank has a periphery provided with a plurality of screw bores each connected to the shaft hole;   the drain cleaner further comprises a plurality of screws screwed into the screw bores of the shank and pressing the clearing member to lock the clearing member onto the shank;   the clearing member has a first end provided with an insert inserted into and the shaft hole of the shank and locked by the screws; and   the clearing member has a second end provided with a drilling portion.   
     
     
         3 . The drain cleaner of  claim 2 , wherein the driving portion of the shank is provided with a coupling which is adapted for being connected with a powered tool, so that the shank is driven and rotated by the powered tool so as to rotate the clearing member. 
     
     
         4 . The drain cleaner of  claim 2 , wherein the driving portion of the shank is driven manually. 
     
     
         5 . The drain cleaner of  claim 2 , wherein the clearing member is made of a metallic wire that is wound successively to form a hollow coiled body, and the drilling portion of the clearing member is enlarged and has a conical spiral shape. 
     
     
         6 . The drain cleaner of  claim 1 , wherein the mounting sleeve is rotatable relative to the handgrip between a first position where the slit of the mounting sleeve aligns with the slit of the support pipe and the slit of the handgrip, so that the slit of the support pipe, the slit of the handgrip and the slit of the mounting sleeve are interconnected, and a second position where the slit of the mounting sleeve misaligns with the slit of the support pipe and the slit of the handgrip, so that the mounting sleeve interrupts a connection between the slit of the support pipe and the slit of the handgrip.
