Description
Technical Field
The utility model belongs to the technical field of the building, concretely relates to multi-drill electric drill is applicable to the construction place that needs bore a plurality of holes.
Background
The electric drill is generally used in building construction, decoration and other objects needing to be drilled, the ordinary electric drill is mainly used for drilling holes through the electric drill and a drill bit, when a plurality of holes need to be drilled uniformly, the electric drill needs to be moved for many times, and the operation is troublesome and low in efficiency.
SUMMERY OF THE UTILITY MODEL
To the technical problem who exists among the background art, the utility model aims at providing a many drill bits electric drill can bore as required and get a hole or bore simultaneously and get a plurality of holes.
The utility model provides a technical problem's technical scheme as follows:
the utility model relates to a multi-drill-bit electric drill, which comprises a drill body, wherein the front end of the drill body is provided with a main drill head, and the main drill head is provided with a main drill bit; the main drilling machine head is movably connected with each auxiliary drilling machine head through a linkage device.
As a further improvement of the present invention, the linkage device includes a main gear disposed on the main drilling head and pinions disposed on each drilling head, the centers of the main gear and each pinion are on the same straight line, and the main gear and each pinion are movably connected by a linkage chain.
As a further improvement of the utility model, the auxiliary drill heads are two.
As a further improvement of the utility model, the fixing frame is a steel frame.
A many drill bits electric drill when using, when only need bore a hole, can only install the main drill bit on main rig, when one row of porous is beaten to needs, can install the main drill bit on main rig, install the assistant drill bit on each assistant rig, open the power of rig fuselage when punching, when main rig rotates, drive the master gear rotation on it, then through the pinion gear rotation of linkage chain drive left and right sides, and then drive the assistant drill head and install the assistant drill bit rotation on the assistant rig, reach the effect that once only bores and gets a plurality of holes.
Compared with the prior art, a many drill bits electric drill novel in design, reasonable, simple structure can singly drill or once drill in a row a plurality of positions according to the construction needs, its easy dismounting, effectual, the practicality is strong.

The parts of the present invention not described in detail are the known techniques of those skilled in the art.
As shown in fig. 1 to 4, the utility model relates to a multi-drill-bit electric drill, which comprises a drill body 4, a main drill head 8 is arranged at the front end of the drill body 4, and a main drill bit 5 is arranged on the main drill head 8, and is characterized in that a fixing frame 7 is arranged at the front side of the drill body 4, a plurality of auxiliary drill heads 9 are symmetrically arranged on the fixing frame 7 relative to the drill body, and an auxiliary drill bit 6 is arranged on each auxiliary drill head 9; the main drill head 8 is movably connected with each auxiliary drill head 9 through a linkage device.
In this embodiment, the linkage device includes a main gear 1 disposed on the main drill head 8 and sub-gears 2 disposed on the sub-drill heads 9, centers of the main gear 1 and the sub-gears 2 are on the same straight line, and the main gear 1 and the sub-gears 2 are movably connected by a linkage chain 3.
In this embodiment, there are two sub-drills 9.
In this embodiment, the fixing frame 7 is a steel frame to increase the stability of the device.
In this embodiment, the fixing frame 7 may be configured to be circular or square according to the requirement of the drilling position, and a suitable linkage device is selected, so as to obtain a corresponding drilling effect.
When the multi-drill-bit electric drill is applied, when only one hole needs to be drilled, the main drill bit can be installed on the main drill bit, when a row of holes needs to be drilled, the main drill bit can be installed on the main drill bit, the auxiliary drill bits are installed on the auxiliary drill bits, a power supply of a drill body is turned on during drilling, when the main drill bit rotates, the main gear on the main drill bit is driven to rotate, then the auxiliary gears on the left and the right are driven to rotate through the linkage chain, and then the auxiliary drill bits on the auxiliary drill bits are driven to rotate, so that the effect of drilling the holes at one time is achieved.
