Ice borer

The invention provides an ice borer. The ice borer comprises a main borer and an auxiliary grasping assembly, wherein the main borer comprises a borer rod and a main borer head arranged at one end of the borer rod; the auxiliary grasping assembly comprises a pressure plate, a protecting plate, a plurality of tack claws, a plurality of connecting shafts and a plurality of springs; the pressure plate sleeves the outer side of the main borer head; the protecting plate is opposite to the pressure plate; the connecting shafts are arranged between the protecting plate and the pressure plate and are connected with the protecting plate and the pressure plate; the springs respectively sleeve the outer sides of the connecting shafts; the tack claws are fixedly arranged on the pressure plate and face the protecting plate; a first through hole and a plurality of second through holes are formed in the protecting plate; the first through hole corresponds to the main borer head; and the second through holes are in one-to-one correspondence to the tack claws. According to the ice borer, the main borer head has effect of directly gripping the ground, the magnitude of force, the direction and the angle cannot be attenuated obviously, and standardization of competition is facilitated; and the tack claws grip the ground simultaneously, damage to an ice surface can be reduced effectively, and maintenance to a competition terrain and a snowfield is facilitated. The ice borer is good in effect of gripping the ground, and is safe and practical.
