[0030] As shown in the drawings, Figures 1-5 The utility model discloses a bench drill noise reduction dust suppression device, which comprises a fixing cylinder 2 and a bottom cylinder 4, the upper end of the fixing cylinder 2 is sleeved on the outer wall of the drill bit fixing seat 104, the drill bit clamp and the drill bit 106 are arranged in the fixing cylinder 2, the lower end of the drill bit 106 extends out of the lower end of the fixing cylinder 2, an annular groove 201 is arranged on the bottom surface of the fixing cylinder 2, the annular groove 201 is arranged along the height direction of the fixing cylinder 2, the annular groove 201 is coaxial with the fixing cylinder 2, the upper part of the bottom cylinder 4 is slidably inserted into the annular groove 201, the drill bit 106 is arranged in the bottom cylinder 4, and the lower end of the bottom cylinder 4 abuts against the top surface of the base 101.
[0031] During normal drilling operation of the bench drill, the fixing cylinder 2 and the bottom cylinder 4 enclose the drill bit 106 and the drilling position inside, thereby reducing the transmission of noise generated during drilling operation to the outside, and the arrangement of the fixing cylinder 2 and the bottom cylinder 4 also limits the scattering of waste generated during drilling operation to the outside. When the drill bit 106 breaks, the flying drill bit 106 is blocked by the fixing cylinder 2 and the bottom cylinder 4, so as to avoid damage to personnel or equipment caused by the flying drill bit 106. During drilling operation, the drill bit fixing seat 104, the drill bit 106 and the drill bit clamp need to move downward, so as to form a hole with a depth on the workpiece. When the drill bit fixing seat 104, the drill bit 106 and the drill bit clamp move downward, the fixing cylinder 2 moves downward together. Since the upper part of the bottom cylinder 4 is slidably inserted into the annular groove 201, the arrangement of the fixing cylinder 2 and the bottom cylinder 4 does not affect the downward movement of the drill bit fixing seat 104, the drill bit 106 and the drill bit clamp.
