The invention relates to a cylinder body capable of automatically adjusting the sizes of plunger holes, which comprises a plunger pump cylinder body, a plurality of bushing holes annularly arranged on the cylinder body and bushings arranged in the bushing holes, a plurality of contraction parts are arranged on the circumference of each bushing, and each contraction part comprises a long through hole contraction groove which is arranged around the circumference of the bushing and along the axial direction of the bushing; the cylinder body is provided with a hoop with a tightening part sleeved on the outer ring of the contraction part of the bushing, and the contraction degree of the contraction part of the bushing is controlled by adjusting the contraction strength of the tightening part through an adjusting part on the hoop, so that the inner diameter of the bushing is changed. According to the cylinder body capable of automatically adjusting the size of the plunger hole, the size of the plunger hole of the c
