Setting.
Further, the limited block mutually agrees with locked groove, and limited block and locked groove contact surface are equipped with non-slip texture.
Further, the lockhole is in the evenly distributed setting of strip in connect cylinder, and lockhole and lock mutually coincide.
Further, agreed with by card slot with buckle between the connecting cylinder and rotary head and be fixedly connected.
The utility model provides a kind of hand electric drill of fast changeable drill bit, has the advantages that
1, this practical can be embedded in the limited block of rotary head outer wall limit with the locked groove of connecting cylinder inner wall, at the same lockhole and
Lock, which mutually coincide, to be fixed, and has achieved the effect that drill bit is conveniently replaceable, and due to lockhole and lock mutually coincide and limited block
It is limited with locked groove, assembling rotary head, easy to operate is moved easily in practical work process, connecting cylinder is not when electricity favourable turn
Friction can be generated with the rotating part of rotary head, therefore the rotating part of rotary head will not damage and rotary head is caused to deform the feelings that can not be removed
Condition, and then manufacture processing cost can be saved.
2, connecting cylinder and rotary head are fixedly connected secondly, being agreed with by card slot and buckle, prevent this kind can quickly more
The connecting cylinder of the hand electric drill of bit change and rotary head, which are subjected to displacement, easily causes the case where falling off, and can reduce connecting cylinder
With the stress concentration phenomenon of rotary head cusp, probability is deformed caused by connecting cylinder and rotary head to reduce.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the ceiling lamp diagrammatic cross-section of the utility model.
In Fig. 1-2: connecting cylinder 1, rotary head 2, card slot 101, lockhole 102, locked groove 103, buckle 201, lock 202, limited block
203。
Specific embodiment
Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment:
It please refers in Fig. 1-2,
A kind of hand electric drill of fast changeable drill bit provided in this embodiment, including connecting cylinder 1 and rotary head 2, even
Rotary head 2 is fixedly installed inside connect cylinder 1,1 outside surrounding of connecting cylinder, which is open, is provided with card slot 101, and 1 inside left of connecting cylinder is opened
Mouth is provided with lockhole 102, and wall opening is provided with locked groove 103 in connecting cylinder 1, and 2 left side upper and lower ends of rotary head are bonded shaft rotation
It is connected with buckle 201,2 left end of rotary head is fixedly installed lock 202, and 2 outer wall surrounding of rotary head is fixedly installed limited block 203.
Further, the quantity of locked groove 103 is six, and six locked grooves 103 are uniformly arranged in 1 inner wall of connect cylinder in " annulus " shape
Column setting, user limit the locked groove 103 of the insertion of limited block 203 of 2 outer wall of rotary head and 1 inner wall of connecting cylinder.
Further, the quantity of limited block 203 is six, and limited block 203 is uniformly arranged in 2 outer wall of rotary head in " annulus " shape
Column setting, lockhole 102 mutually coincide with lock 202 to be fixed, and has achieved the effect that drill bit is conveniently replaceable, due to lockhole 102
It mutually coincide with lock 202 and limited block 203 is limited with locked groove 103.
Further, limited block 203 mutually agrees with locked groove 103, and limited block 203 and 103 contact surface of locked groove are equipped with and prevent
Sliding lines is moved easily assembling rotary head, easy to operate in practical work process, when electricity favourable turn connecting cylinder 1 will not with turn
The case where first 2 rotating part generates friction, therefore the rotating part of rotary head 2 will not damage and cause the deformation of rotary head 2 that can not remove.
Further, lockhole 102 is in the evenly distributed setting of strip in connect cylinder 1, and lockhole 102 and lock 202 are mutually
It coincide, the stress concentration phenomenon of connecting cylinder 1 and 2 cusp of rotary head deforms probability caused by connecting cylinder 1 and rotary head 2 to reduce.
Further, agreed with by card slot 101 with buckle 201 between connecting cylinder 1 and rotary head 2 and be fixedly connected, pass through card slot
101 agree with buckle 201 and are fixedly connected connecting cylinder 1 and rotary head 2, prevent the hand-held electricity of this kind of fast changeable drill bit
The connecting cylinder 1 of drilling machine and rotary head 2 are subjected to displacement and easily cause the case where falling off.
Working principle:
When using a kind of hand electric drill of fast changeable drill bit provided in this embodiment, user is by rotary head 2
The insertion of limited block 203 of outer wall and the locked groove 103 of 1 inner wall of connecting cylinder are limited, while lockhole 102 and lock 202 mutually kiss
Conjunction is fixed, and has achieved the effect that drill bit is conveniently replaceable, due to lockhole 102 and lock 202 mutually coincide and limited blocks 203 and
