The invention discloses a hanging clamp for an inner hole electroplating part. The hanging clamp for the inner hole electroplating part comprises a clamp body connected with a cathode of a power supply and has conductive performance; the clamp body is provided with a through hanging hole, the hanging hole is used for enabling a shaft shoulder of a to-be-plated part to abut against the clamp body after the to-be-plated part is arranged in a penetrating mode so as to vertically hung and support the to-be-plated part and form the same electric conductor with the to-be-plated part; the hanging clamp further comprises an anode component which is connected with an anode of the power supply and has the conductive performance, the upper end of the anode component is in insulated connection with the clamp body, the lower end of the anode component is used for extending into a shaft hole of the to-be-plated part hung on the clamp body so as to enable power lines to be uniformly distributed in the shaft hole, and then the thickness of a electroplated layer on the surface of the shaft hole is guaranteed to be uniform and consistent; and the hanging clamp further comprises protective cylinders,the protective cylinders are used for sleeving an outer circle of the shaft section needing to be protected and with the outer circle to be protected on a to-be-plated part. According to the hangingclamp, the power lines are enabled to be uniformly distributed in the shaft hole of the to-be-plated part, so that the thickness of the electroplated layer on the surface of the shaft hole is guaranteed to be uniform and consistent.
