1 . An anti-slide sheath of a grip, comprising a sheath body configured for attaching to the grip, wherein the sheath body comprises a contact surface located outside the sheath body and a connection surface contacting a surface of the grip, both the contact surface and the connection surface are made of flexible material, and a connection portion is provided on the sheath body. 
     
     
         2 . The anti-slide sheath of a grip according to  claim 1 , wherein an adhesive layer is provided on the connection surface, and the sheath body is bonded to the grip. 
     
     
         3 . The anti-slide sheath of a grip according to  claim 1 , wherein a zipper is provided on two opposite sides of the sheath body, and the sheath body forms a cylindrical structure through the zipper. 
     
     
         4 . A method for using the anti-slide sheath of a grip according to  claim 1 , comprising the following steps:
 coating a volatile lubricant on an outer surface of the connection surface or the grip; and   mounting the sheath body to a target position of the grip, until the volatile lubricant is completely volatilized.   
     
     
         5 . The method for using the anti-slide sheath of a grip according to  claim 4 , wherein the volatile lubricant is one or more selected from the group consisting of water, alcohol, acetic acid and ethyl acetate. 
     
     
         6 . A method for fabricating the anti-slide sheath of a grip according to  claim 1 , comprising the following steps:
 S 1 , adding silicone rubber as feedstock into an annular mold cavity;   S 2 , heating up and pressurizing the annular mold cavity, so that the silicone rubber is cured and molded through high-temperature vulcanization;   S 3 , applying a force to a surface of the molded silicone rubber to separate the silicone rubber from a surface of the annular mold cavity; and   S 4 , opening the annular mold cavity to remove the molded silicone rubber.   
     
     
         7 . The method for fabricating the anti-slide sheath of a grip according to  claim 6 , wherein a temperature in S 2  is from 180° C. to 200° C. 
     
     
         8 . The method for fabricating the anti-slide sheath of a grip according to  claim 7 , wherein an opening is provided in at least one end of the annular mold cavity. 
     
     
         9 . The method for fabricating the anti-slide sheath of a grip according to  claim 8 , wherein the mold comprises a mold cylinder for molding an outer surface of the sheath body and a mold core for molding an inner surface of the sheath body;
