description The utility model relates to a diameter-adjustable injection head, which comprises an injection head body, an annular mounting groove is arranged on the outer circumferential surface of the injection head body, a split ring sleeved on the outer side of the injection head body is arranged in the annular mounting groove, and a compensation ring sleeved on the outer side of the injection head body and accommodated in the annular mounting groove is arranged on the inner side of the split ring. The compensation ring is pushed by a pushing assembly arranged at the rear end of the injection head body to move forwards along the annular mounting groove, the outer surface of the compensation ring is in wedge-shaped fit with the inner surface of the split ring, and when the compensation ring moves forwards, the compensation ring pushes the split ring to expand outwards in the radial direction of the injection head body through wedge-shaped fit. The injection head is reasonable in structural design, when the split ring l
