Description

Drill bit dust keeper Technical Field The utility model relates to the technical field of drill bit dust prevention, in particular to a drill bit dust prevention device. Background The drill bit is a cutting tool for drilling holes in materials, and is widely applied to the fields of metal processing, woodworking, construction, mining and the like, however, a large amount of dust is scattered in the drilling process, so that dust covers are usually installed around the drill bit for protecting the health of operators and keeping the working environment clean, and the dust scattering is reduced by attaching a rubber or plastic ring to a wall surface. However, after the dust cover is installed, the contact area between the tip end of the drill bit and the working surface is shielded, and an operator is difficult to directly observe the alignment condition of the drill bit and the marking point during positioning, so that during positioning, the dust cover is usually detached firstly to roughly position, after a trace is left by slightly drilling, the dust cover is returned again to finish drilling, the operation steps are complicated, and the working efficiency is influenced. Based on this, a drill bit dust-proof device has been proposed to solve the above-mentioned problems. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides the drill bit dustproof device, after the dustproof cover is directly compressed, the drill bit tip is leaked to be positioned, the dustproof cover is not required to be detached, and the operation is more convenient. In order to achieve the above purpose, the utility model provides a drill bit dustproof device, comprising: The support seat is provided with a fixing assembly for limiting the drill bit; The telescopic sleeve is arranged on the supporting seat through the mounting plate and can move in a telescopic way on the supporting seat; The end fixing of flexible cover has solid fixed ring, be fixed with the fixed plate on the supporting seat, gu fixed plate internal fixation has fixed pipe, fixed pipe is fixed in the mounting panel, still be provided with the pencil in the fixed pipe, the both ends of pencil run through fixed pipe and fixed with solid fixed ring's border department, the accessible pulling pencil makes flexible cover compression, exposes the drill bit, can conveniently treat drilling position and fix a position. Further, the fixed subassembly is including the activity setting up the U type splint on the supporting seat, the both ends of U type splint run through and extend to the supporting seat below and lock through the locking piece, pass the U type splint with the drill bit sleeve, lock the drill bit sleeve on the supporting seat through the U type splint. Furthermore, the locking piece is a nut which is sleeved at the end part of the U-shaped clamping plate through threads, the nut is screwed down, and the drill bit can be locked on the supporting seat through the U-shaped clamping plate. Further, be provided with the sealed bearing that corresponds with the flexible cover opening in the mounting panel, the drill bit rotates, and sealed bearing can make drill bit and flexible cover have a certain distance to make the protection casing can not follow and rotate jointly. Further, the outside cover of flexible cover is equipped with reset spring, reset spring is located between solid fixed ring and the mounting panel, and reset spring's tension still can make flexible cover more quick recovery, and makes gu fixed ring and wall laminating more inseparable, prevents that the dust from spilling over.
