<p>A connecting handle for a bimetal hole saw comprises a connecting handle body (1) and transmission dowels (2). The connecting body (1) comprises a power connecting end (11), a drill saw connecting end (12) provided with hole saw connecting threads and a pilot drill installation hole, and an installation part provided with installation through holes. The installation part is arranged between the power connecting end (11) and the drill saw connecting end (12). The transmission dowels (2) are arranged in the installation through holes and can move axially along the installation through holes. The connecting handle for the bimetal hole saw also comprises a hole saw stabilizing apparatus (3). The hole saw stabilizing apparatus (3) is arranged on the connecting handle body (1) through a threaded structure (4) and can move along an axis of the connecting handle body (1) through the threaded structure (4). The hole saw stabilizing apparatus (3) stabilizes a hole saw (6) by moving along the axis of the connecting handle body (1). After the hole saw (6) is connected to the drill saw connecting end (12), and transmission dowels (2) are pushed into the dowel holes, the hole saw stabilizing apparatus (3) is further twisted so as to tightly attached to a top surface of the hole saw (6), thus the hole saw (6) will not shake during use.</p> |
