     Preferably, wherein the second handle and the third handle are connected by clamping or fastening; 
     Preferably, one end of the second handle is provided with internal thread, a connecting portion is provided on one end of the third handle, and outer side wall of the connecting portion is provided with external thread; the detachable connection between the second handle and the third handle can be realized by the cooperation between the external thread on the extension portion and the internal thread on the second handle. 
     Preferably, the first handle, the second handle and the third handle are all cylindrical. 
     Preferably, the diameter of one end of the first handle near the fixing portion is smaller than that of another end of the same near the extension portion. 
     Preferably, the diameter of the extension portion is smaller than that of the first handle. 
     Preferably, two sides of the extension portion are symmetrically arranged with connecting hole, the hanging ring is fastened in the connecting holes. 
     Preferably, the functional tools can be brush, shovel or knife. 
     Preferably, the first handle is made of wood, plastic or silica gel, and the second handle and the third handle are both made of stainless steel. 
     The invention has following advantageous effects:
         the invention provides a portable multifunctional handle with flexible structure, comprising fixedly connected first handle and second handle, one end of the second handle can be detachably connected with third handle, the third handle can be connected to multifunctional tools, such as brush, shovel and knife etc, thereby realizing that various tools share one handle, which not only can save storage space of tools, but also can reduce energy consumption and cost, and relive resource pressure; the diameter of the first handle in the invention is growing bigger from one end near the second handle to another end near the extension portion, which is ergonomic design that is easy to grasp and labor-saving in operation; a fixing portion is provided on the connection position between the first handle and the second handle, the outer side wall of the fixing portion is fixedly connected with a fastening piece, which can prevent the first handle from being damaged by pressure of the second handle when the tool is used, thereby extending the service life of the first handle.
