[0002] The electric drill chuck is an important part of the electric drill. Its function is to replace the drill bit and clamp the drill bit. At present, there are two main types of electric drill chucks. One is the manual type. Clamping, not only the replacement of the drill bit is slow, but also the untightened chuck is easy to cause hidden dangers during clamping, and there is another kind of automatic clamping, but this kind of chuck has too much torsion force on the hand when clamping, which is very difficult. It is easy to cause hand injury, and the current electric drill has almost no dustproof function, which will generate a lot of dust when drilling, which greatly affects the health of workers

Embodiment Construction
[0019] Combine below Figure 1-6 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are defined as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0020]A dust-proof electric drill chuck that can quickly clamp drill bits described in conjunction with accompanying drawings 1-6 includes a main box body 10, and a rotating block 24 is connected to the main box body 10 in rotation, and the rotating block 24 The left end face is fixedly connected with a chuck rotating base 62, and the chuck rotating base 62 is rotatably connected with a chuck seat 27 which is connected with the left end face of the rotating block 24 and extends rightward to the outside. The left end face of the seat 27 is rotatably connected with a clip block nut seat 36, and the left end face of the clip block nut seat 36 is rotatably connected with a collet 76. The...

The invention relates to the related field of electric drills, and discloses a dustproof electric drill chuck capable of quickly clamping a drill bit. The dustproof electric drill chuck comprises a main box body; a rotating block is connected in the main box body in a rotary fit mode; a chuck rotating base is fixedly connected to the left end surface of the rotating block; and the drill bit is clamped by rotating a quickly closed clamping block, so that the drill bit can be quickly clamped, and the operation efficiency is greatly improved; an annular rotating block can rotate relative to a clamping block nut seat, so that the hands of a user are prevented from being injured due to overlarge torsion of the chuck, and meanwhile, a transmission spur gear can rotate relative to a transmissiongear shaft sleeve, so that the situation that the service life of an electric drill is influenced due to overlarge counter-acting force borne by a transmission shaft when the drill bit is clamped is avoided; and the rotating block rotates to drive a water pump to rotate, so that when the electric drill performs drilling operation, a water mist spray head can spray water mist, dust generated duringdrilling is reduced, and the influence of the dust on the health of operators is greatly reduced.
