Body surface preferably pierces object.
Drill hammer is a kind of equipment for clamping on electric impact drill, to concrete foundation, wall, brick wall, granite
Carry out it is boring, to install expansion bolt, the fasteners such as plastic expansion pipe in hole.
But there are some drawbacks in use in traditional electric drill, such as:
Traditional electric drill directly screws the thread bush outside electric drill mostly and drill bit is passed through knob when installing drill bit
It is connected to inside electric drill, the direction of rotation of electric drill and the tightening direction of thread bush are identical at work, therefore drill bit can use
When it is more more stubborn tighter, therefore, using electric drill carry out more bit change when be difficult to back out on drill bit.
Utility model content
The purpose of this utility model is to provide a kind of drill bit installing mechanisms, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of drill bit installing mechanism, including drill bit are tight
Gu set, drill insertion hole, electric drill mounting base and drill bit clamping plate, the fixation of electric drill mounting base outer surface offers fastening thread, institute
It states and drill bit adapter sleeve is equipped with by fastening thread screw thread outside electric drill mounting base, the drill bit adapter sleeve top center fixation is opened
Equipped with drill bit limit hole；Drill insertion hole is offered inside the electric drill mounting base, the electric drill mounting base side wall uniformly open by fixation
If the clamping plate slot top inner wall is fixedly welded with shaft there are four clamping plate slot, is rotated and pacified by shaft inside the clamping plate slot
Equipped with drill bit clamping plate, the drill bit clamping plate is matched with the installation end of drill bit.
Further, at drill bit limit hole center and drill insertion hole center is everywhere on same central axes.
Further, the drill bit clamping plate is sector.
Further, the drill bit clamping plate is four, and is mounted on electric drill mounting base side wall in cross.
Further, the drill bit adapter sleeve is matched with drill bit clamping plate.
Compared with prior art, the utility model has the beneficial effects that
It is plugged on inside drill insertion hole by the way that electric drill head is passed through drill bit limit hole, by screwing drill bit adapter sleeve, so that
Drill bit adapter sleeve squeezes into drill bit clamping plate inside drill insertion hole, and drill bit clamping plate clamps the fixation that drill bit installation end opens up at this time
Slot so that drill bit by drill bit Boards wall inside drill insertion hole, the utility model relative to traditional drill bit fixed mechanism come
It says, it is simpler to the fixed form of drill bit, and easily facilitate and drill bit is dismantled.
