         2 . The mesh frame according to  claim 1 , wherein a minimum distance between an opening of the recess and an outer edge of the side frame is greater than 2 mm. 
     
     
         3 . The mesh frame according to  claim 1 , wherein inner walls of two sides of the recess are parallel to each other, wherein the inner walls of the two sides of the recess are arranged to face each other. 
     
     
         4 . The mesh frame according to  claim 3 , wherein a width between the inner walls of the two sides of the recess ranges from 2 to 5 mm. 
     
     
         5 . The mesh frame according to  claim 3 , wherein heights of the inner walls of the two sides of the recess both range from 5 to 20 mm. 
     
     
         6 . The mesh frame according to  claim 1 , wherein a minimum distance between the inner wall of the recess and an inner edge of the side frame is greater than 2 mm. 
     
     
         7 . The mesh frame according to  claim 1 , wherein an arc chamfer is arranged at an opening of the recess. 
     
     
         8 . The mesh frame according to  claim 1 , wherein the first face of the side frame is provided with the mesh, an outer edge of the mesh being snap-fitted into the recess; wherein
 a thickness of the outer edge of the mesh is greater than a minimum width of the recess; or   the outer edge of the mesh is elastic.   
     
     
         9 . The mesh frame according to  claim 1 , wherein the first face of the side frame is provided with the mesh, an outer edge of the mesh being snap-fitted into the recess; wherein
 the outer edge of the mesh is fixed with a snap strip, the snap strip being snapped into the recess; or   the mesh frame comprises a snap strip, the snap strip being snapped into the recess, and the outer edge of the mesh is clamped between the snap strip and the recess.   
     
     
         10 . The mesh frame according to  claim 2 , wherein a distance from the opening of the recess to an outer edge of the mesh frame is l 1 , and a distance from a bottom wall of the recess to the outer edge of the mesh frame is l 2 , wherein l 1 <l 2 , such that the recess is obliquely arranged. 
     
     
         11 . The mesh frame according to  claim 2 , wherein an x direction is a direction horizontally pointing from an outer side of the mesh frame to an interior, a y direction is a depthwise direction pointing from the bottom wall of the recess to the opening, and the x direction and they direction define an angle within a range of 90°<α<180°. 
     
     
         12 . The mesh frame according to  claim 2 , wherein the recess is arranged to be annular, and surround an edge of the first face of the mesh frame by one turn. 
     
     
         13 . The mesh frame according to  claim 2 , wherein two recesses are symmetrically arranged, which are respectively arranged on two opposite edges of the first face of the mesh frame, by receiving and snap-fitting of the two sides of the mesh, the mesh being fixed to the mesh frame. 
     
     
         14 . A chair, comprising the mesh frame as defined in  claims 1 . 
     
     
         15 . The chair according to  claim 14 , wherein a minimum distance between an opening of the recess and an outer edge of the side frame is greater than 2 mm. 
     
     
         16 . The chair according to  claim 14 , wherein inner walls of two sides of the recess are parallel to each other, wherein the inner walls of the two sides of the recess are arranged to face each other. 
     
     
         17 . The chair according to  claim 16 , wherein a width between the inner walls of the two sides of the recess ranges from 2 to 5 mm. 
     
     
         18 . The chair according to  claim 16 , wherein heights of the inner walls of the two sides of the recess both range from 5 to 20 mm. 
     
     
         19 . The chair according to  claim 14 , wherein a minimum distance between the inner wall of the recess and an inner edge of the side frame is greater than 2 mm. 
     
     
         20 . The chair according to  claim 14 , wherein an arc chamfer is arranged at an opening of the recess.
