Abstract
The utility model discloses a twin-collet electric drill which comprises a first drill collet, a second drill collet, a body shell of the electric drill, an electric motor and a switch. The first drill collet and the second collet are provided on the twin-collect fixing shell connected to the body shell of the electric drill by rotating structure. The rotating shaft of the first drill collet and the rotating shaft of the second drill shaft are connected to the rotating shaft clutch of the electric motor respectively. The twin-collet drill acquires two drill collets on one electric drill, which enables the two different drill heads can be installed in the same electric drill simultaneously. Thus, trouble of changing drill head is avoided during drill works. All that needs to be done is simply turn two collets to complete replacement, which simplifies the process. The twin-collet electric drill has simply structure, while the rotation of two drill collets is easy too. The on-off between the rotating shaft of the drill collet and the rotating shaft of the electric motor can be done easily and quickly, and the junction is firm and secure, which prevents risky factors in changing drill head and guarantees work safety.
