         6 . The device for attaching and detaching a toothbrush head according to  claim 1 , wherein the head has protruding plugs thereon corresponding to the holes on the head attaching portion, the pressing portion applies a force onto the head attaching portion toward the head when the holes on the head attaching portion align with the protruding plugs on the head so that the protruding plugs pass through the holes, thereby attaching the head to the handle. 
     
     
         7 . The device for attaching and detaching a toothbrush head according to  claim 1 , wherein the pushing posts are formed in the shape of a cross. 
     
     
         8 . The device for attaching and detaching a toothbrush head according to  claim 1 , wherein the protruding plugs on the head pass through the holes on the head attaching portion to attach the head to the handle, the pushing posts pass through the holes and apply a force onto the protruding plugs to cause the protruding plugs to disengage from the holes, thereby detaching the head from the handle. 
     
     
         9 . The device for attaching and detaching a toothbrush head according to  claim 1 , wherein the device for attaching and detaching a toothbrush head further comprises at least one cleaning brush. 
     
     
         10 . The device for attaching and detaching a toothbrush head according to  claim 9 , wherein a concavity used as a cleaning brush accommodating cavity is formed in at least one outer side wall of the first housing. 
     
     
         11 . The device for attaching and detaching a toothbrush head according to  claim 10 , wherein a projection extends from the bottom wall of the concavity, the projection can pass through a hole in the cleaning brush to hold the cleaning brush in place in the concavity. 
     
     
         12 . The device for attaching and detaching a toothbrush head according to  claim 1 , wherein the lining component is formed separately from the first housing and is mounted in the first housing. 
     
     
         13 . A toothbrush kit comprising:
 a device for attaching and detaching a toothbrush head according to  claim 1 ; and   one or both accommodated in the head mounting cavity and the head detaching cavity and selected from a toothbrush head, a toothbrush handle and a toothbrush.
