Drilling machine and clamping pincers for machine

The invention discloses a machine tool and clamping pincers for the machine. The clamping pincers for the machine comprise a pincers base (100) and jaw plates (200 and 300) which are distributed in a paired mode. In the jaw plates (200 and 300) which are distributed in the paired mode, one jaw plate is fixed to a fixing pincers body (110) of the pincers base (100), and the other jaw plate is fixed to a movable pincers body (120) of the pincers base (100). Clamping faces (210 and 310) of the jaw plates (200 and 300) distributed in the paired mode comprise slopes and horizontal bearing faces located on the bottom of the slopes. The slopes face the bottom of the pincers base (100). The clamping faces (210 and 310) of the jaw plates (200 and 300) distributed in the paired mode can get close to the fixing pincers body (110) along with the movable pincers body (120) to form a dovetail type clamping space used for clamping workpieces to be machined. The slopes of the two clamping faces (210 and 310) are used for bei
