Twisting mechanism for duster

Abstract

The present invention relates to a twisting mechanism for a duster for setting one end of a dusting cloth of the duster as a fixed end while setting the opposite end as a rotatable end. The twisting mechanism primarily comprises: a brace, inserted form the rear end through the front end of the dusting cloth and coupled with the front end of the dusting cloth to set it as a fixed end; and a rotating mechanism, pivotally connected to the rear end of the brace and hooking the rear end of the dusting cloth for driving the dusting cloth to twist into a spiral dusting cloth having a 360-degree dusting surface on the brace.

1 . A twisting mechanism for a duster, comprising:
 a brace, inserted form the rear end through the front end of the dusting cloth and coupled with the front end of the dusting cloth; and   a rotating mechanism, which is pivotally connected to the rear end of the brace and hooking the rear end of the dusting cloth to set the rear end of the dusting cloth as the rotatable end, for pulling the dusting cloth to rotate and twist into a spiral shape having a 360-degree dusting surface on the brace.   
   
   
       2 . The twisting mechanism of  claim 1 , wherein a handle is settled at the front end of the rotating mechanism. 
   
   
       3 . The twisting mechanism of  claim 1 , wherein a fork portion is formed at the tip of the brace for being coupled with the front end of the dusting cloth. 
   
   
       4 . The twisting mechanism of  claim 1 , wherein at least one first hook assembly having a pair of hooks is provided at the rotating mechanism for hooking the rear end of the dusting cloth. 
   
   
       5 . The twisting mechanism of  claim 1 , wherein the rotating mechanism is a rotator or a torque mechanism that can be rotated clockwise or anticlockwise. 
   
   
       6 . The twisting mechanism of  claim 4 , wherein the first hook assembly are arranged at two sides of the surface of the rotating mechanism. 
   
   
       7 . The twisting mechanism of  claim 5 , wherein a first hook assembly having a pair of hooks and a second hook assembly having a pair of hooks are provided at the rotating mechanism. 
   
   
       8 . The twisting mechanism of  claim 7 , wherein the hooks of the first hook assembly are arranged at two sides of the surface of the rotating mechanism and the angle therebetween is 180-degree. 
   
   
       9 . The twisting mechanism of  claim 7 , wherein the hooks of the second hook assembly are arranged at two sides of the surface of the rotating mechanism and the angle therebetween is 180-degree. 
   
   
       10 . The twisting mechanism of  claim 2 , wherein a coupling structure is provided at the end of the handle for being further coupled with an extension structure. 
   
   
       11 . The twisting mechanism of  claim 10 , wherein the coupling structure comprises a recess passing through the upper and lower surfaces of the handle for pivotally receiving the extension structure and a plurality of positioning protrusions provided on two walls of the recess.
