The jig for surface treatment according to the present disclosure passes a hanging rod through the metal plate. Thereby, the jig for surface treatment will not contact with a processed surface of the metal plate and hence making no apparent flaws on the processed surface and maintaining completeness processed surface. In addition, the jig for surface treatment can load a plurality of metal plates at a time, performing surface treatment on the plurality of metal plates simultaneously, and thus improving productivity and practicability. ## Claims ### Claim 1 A jig used for fixing a metal plate having a bearing, during surface treatment, comprising: a top connecting shaft; a hanging rod, having an end connected pivotally to said top connecting shaft; a fixing device, for fixing the other end of said hanging rod; and a bottom connecting shaft, connected to the bottom of said fixing device; wherein, said hanging rod passes through said bearing of said metal plate and said hanging rod is fixed by said fixing device during surface treatment, and after surface treatment is completed, and said hanging rod is escaped from said fixing device, which allows for the removal of said metal plate. ### Claim 2 (depends on 1) The jig for surface treatment of claim 1, wherein said top connecting shaft has a pivot part, and an end of said hanging rod is connected pivotally to said pivot part. ### Claim 3 (depends on 2) The jig for surface treatment of claim 2, wherein an end of said hanging rod has a steering mechanism connected pivotally to said pivot part and driving said hanging rod to rotate. ### Claim 4 (depends on 3) The jig for surface treatment of claim 3, wherein said steering mechanism is a hinge. ### Claim 5 (depends on 3) The jig for surface treatment of claim 3, wherein said steering mechanism is a ball joint or a universal joint. ### Claim 6 (depends on 1) The jig for surface treatment of claim 1, wherein said fixing device has a trench and said hanging rod is wedged in said trench. ### Claim 7 (depends on 6) The jig for surface treatment of claim 6, wherein the other end of said hanging rod has a positioning member wedged in said trench. ### Claim 8 (depends on 6) The jig for surface treatment of claim 6, wherein said trench has at least a blocking member for blocking said hanging rod. ### Claim 9 (depends on 1) The jig for surface treatment of claim 1, further comprising an elastic fixing member, the elastic fixing member is put-around said hanging rod for fixing said metal plate. ### Claim 10 (depends on 9) The jig for surface treatment of claim 9, wherein said elastic fixing member is a spring, a rubber block, or a silica gel block. ### Claim 11 (depends on 1) The jig for surface treatment of claim 1, further comprising a carrying frame for disposing said top connecting shaft and said bottom connecting shaft. ### Claim 12 A jig used for fixing a metal plate having a bearing, during surface treatment, comprising: a top connecting shaft, having a pivot part; a hanging rod, having an end, said end of said hand rod having a steering mechanism connected pivotally to said pivot part of said top connecting shaft, said pivot part of said top connecting shaft driving said hanging rod to rotate, and said end of said hanging rod passing through said bearing of said metal plate; a fixing device, for fixing the other end of said hanging rod; and a bottom connecting shaft, connected to the bottom of said fixing device. ### Claim 13 (depends on 12) The jig for surface treatment of claim 12, wherein said steering mechanism is a hinge. ### Claim 14 (depends on 12) The jig for surface treatment of claim 12, wherein said steering mechanism is a ball joint or a universal joint. ### Claim 15 (depends on 12) The jig for surface treatment of claim 12, wherein said fixing device has a trench and said hanging rod is wedged in said trench. ### Claim 16 The jig for surface treatment of claiml5, wherein the other end of said hanging rod has a positioning member wedged in said trench. ### Claim 17 (depends on 15) The jig for surface treatment of claim 15, wherein said trench has at least a blocking member for blocking said hanging rod. ### Claim 18 (depends on 17) The jig for surface treatment of claim 17, wherein said elastic fixing member is a spring, a rubber block, or a silica gel block. ### Claim 19 (depends on 12) The jig for surface treatment of claim 12, further comprising an elastic fixing member, the elastic fixing member is put around said hanging rod for fixing said metal plate. ### Claim 20 (depends on 12) The jig for surface treatment of claim 12, further comprising a carrying frame for disposing said top connecting shaft and said bottom connecting shaft.
