Weed removing tool

Abstract

A weed removing tool includes a tool body and a cover body arranged on an air outlet on the tool body. The cover body is provided with a support frame forming a heat dissipation gap between an opening and an object to be processed during operation. Such a structure prevents the problem that the entire heating object is over-heated to damages because the cover body is coated over the heating object and is not timely removed. In addition, with such a structure, during heating, the force applied by the hands may be reduced by means of the support frame.

What is claimed is: 
     
         1 . A weed removing tool, comprising:
 a tool body and a cover body arranged on an air outlet on the tool body, wherein the cover body is provided with a support frame fanning a heat dissipation gap between an opening and an object to be processed during operation.   
     
     
         2 . The weed removing tool according to  claim 1 , wherein the support frame comprises a fixing portion connected to the cover body, and a support end acting on the object to be processed and forming the heat dissipation gap. 
     
     
         3 . A weed removing tool, comprising:
 a tool body and a cover body arranged on an air outlet, the cover body having a heat dissipation port; wherein a cover sheet for regulating the size of the heat dissipation port to thus regulate the temperature at the air outlet is arranged at a position on the cover body corresponding to the heat dissipation port.   
     
     
         4 . The weed removing tool according to  claim 3 , wherein the cover sheet is connected to the cover body, and is movable relative to the cover body. 
     
     
         5 . The weed removing tool according to  claim 4 , wherein the cover sheet is an outer cover coating the cover body, the outer cover axially moving relative to the cover body and being fixed to a selected position. 
     
     
         6 . The weed removing tool according to  claim 4 , wherein the cover sheet is an outer cover coating an outer side of the cover body, the outer cover being provided with a limiting port matching with the heat dissipation port, and the outer cover rotating relative to the cover body. 
     
     
         7 . The weed removing tool according to  claim 3 , wherein the air outlet of the tool body is further provided with a root damage probe. 
     
     
         8 . The weed removing tool according to  claim 7 , wherein the root damage probe is a hollow conical structure, and a top portion of the probe is provided with an air outlet hole. 
     
     
         9 . The weed removing tool according to  claim 8 , wherein heat dissipation holes are arranged on a side wall of the root damage probe. 
     
     
         10 . The weed removing tool according to  claim 7 , wherein an edge of the air outlet hole at the top portion the root damage probe is a blade portion. 
     
     
         11 . The weed removing tool according to  claim 7 , wherein the root damage probe is a solid metal cone. 
     
     
         12 . The weed removing tool according to  claim 1 , further comprising at least one wheel body arranged on a side face of the cover body and operable to support the weed removing tool. 
     
     
         13 . The weed removing tool according to  claim 1 , further comprising a free edge, a plane where the freed edge of the cover body is located forming an inclined angle with a plane perpendicular to an air outlet direction of the air outlet. 
     
     
         14 . The weed removing tool according to  claim 1 , wherein the tool body and the cover body are integrally formed. 
     
     
         15 . The weed removing tool according to  claim 3 , further comprising at least one wheel body arranged on a side face of the cover body and operable to support the weed removing tool. 
     
     
         16 . The weed removing tool according to  claim 3 , further comprising a free edge, a plane where the freed edge of the cover body is located forming an inclined angle with a plane perpendicular to an air outlet direction of the air outlet. 
     
     
         17 . The weed removing tool according to  claim 3 , wherein the tool body and the cover body are integrally formed. 
     
     
         18 . The weed removing tool according to  claim 7 , further comprising at least one wheel body arranged on a side face of the cover body and operable to support the weed removing tool. 
     
     
         19 . The weed removing tool according to  claim 7 , further comprising a free edge, a plane where the freed edge of the cover body is located forming an inclined angle with a plane perpendicular to an air outlet direction of the air outlet. 
     
     
         20 . The weed removing tool according to  claim 7 , wherein the tool body and the cover body are integrally formed.
