Zusammenfassung:	The utility model relates to a light path adjusting device with variable light spot size and a laser cutting head, the light path adjusting device comprises a first control mechanism, a second control mechanism, a first lens group, a second lens group and a focusing lens group, and the first lens group, the second lens group and the focusing lens group are coaxially arranged. The first control mechanism is connected with the first lens group, and the first control mechanism can drive the first lens group to move on the axis of the first lens group. The second control mechanism is connected with the second lens group, and the second control mechanism can drive the second lens group to move on the axis of the second lens group. And the first control mechanism and the second control mechanism are linked to adjust the size and divergence angle of the light spot. The light spot size and the divergence angle are adjusted in a multi-gear mode, and a cutting process with the best effect can be adopted for plate cutti
