The invention relates to the technical field of snow removing equipment, in particular to an adjusting mechanism and a snow removing shovel. The adjusting mechanism comprises a supporting part, a rotating part, an adjusting part and a locating part; the supporting part, the rotating part, the adjusting part and the locating part are sequentially and rotationally connected end to end, and the included angle between the rotating part and the locating part can be changed by adjusting the length of the adjusting part; the supporting part is arranged on the rotating part and is connected with and one end of the adjusting part. The snow removing shovel comprises a main plate, an obstacle receding mechanism and the adjusting mechanism, the main plate is fixedly arranged on one side of a main frame of the obstacle receding mechanism, and the adjusting mechanism is fixedly arranged at the other side of the main frame. The included angle between the rotating part and the locating part can be changed through stretching and contracting of the adjusting part, due to fixed connection between the locating part and the snow removing shovel and rotation of the rotating part, the locating part is driven under support of the supporting part to rise or fall so that the snow removing shovel can rise or fall, and the operation state and the transfer state can be switched; and the snow removing shovel can be adjusted according to road surface height and pressure.
