The invention relates to an improved anti-slip tool chuck. The improved anti-slip tool chuck comprises a tool rod, a barrel clip and a nut, an inner taper hole matched with the outer taper of the barrel clip is formed in the tool rod, the barrel clip is clamped in the inner taper hole of the tool rod, external threads are formed in the front of the tool rod, the nut is arranged at the front end of the barrel clip and in thread connection with the external threads in the front of the tool rod, a column-shaped cavity is formed in the bottom of the inner taper hole, the tail of a tool passes through the barrel clip and is arranged in the column-shaped cavity, arc-shaped blocks matched with the tool are arranged in the column-shaped cavity, the arc-shaped blocks are connected with the inner wall of the column-shaped cavity through a spring, thread holes communicated with the column-shaped cavity is formed in the side wall of the tool rod, bolts are arranged in the thread hole, and the bolts pass through the spring to contact with the arc-shaped blocks. By means of the scheme, the clamping force between the arc-shaped blocks and the tool is regulated through regulating the depth of the bolts in the thread holes, the tool slip is effectively avoided, and the clamping force of the tool chuck for the tool is further improved.
