Description
Technical field
The present invention relates to a kind of electric drill, more particularly to for a kind of electric drill with manual lock.
Background technology
Electric drill and electric impact drill need often to dismantle drill bit in use, for ease of assembly and disassembly usually using manually fastened
Drill chuck, user can only be by the dismounting that switch machine to realize to drill bit when using tightening drill chuck, this just very not side
Just.
Invention content
For the deficiencies in the prior art, the present invention provides a kind of electric drill with manual lock, drill bit does not need to
Special equipment can also be dismantled.
The present invention is achieved through the following technical solutions：A kind of electric drill with manual lock, including drill bit, the drill bit
Be fixed on drill chuck, further include manual lock construction, the manual lock construction include from lock nut, self-lock pin, locking spring and from
Closing piece, the end that the self-lock pin is fixed on from lock nut are provided with through-hole on the self-locking block, and the self-lock pin is inserted into institute
State in through-hole, the locking spring is sleeved on the self-lock pin, the both ends of spring difference position with it is described from lock nut and described
Self-locking block is in contact, and setting is fluted at the position opposite with the through-hole on the drill bit.In use, self-lock pin is in locking bullet
Under the action of spring, the groove is detached from, at this time drill bit can be freely rotated, and when needing to dismantle drill bit, then can press certainly
Lock nut, self-lock pin overcome the elastic force of self-locking spring to be inserted into the groove, at this time rotation manual lock construction, with regard to that can drive drill bit
It rotates together, realizes the dismounting of drill bit, it is very convenient without special tool.
In above-mentioned technical proposal, it is preferred that further include screw, the screw is fixed on the end of the drill bit.
The present invention has the advantages that：In use, self-lock pin under the action of locking spring, is detached from the groove,
At this time drill bit can be freely rotated, and when needing to dismantle drill bit, then can press from lock nut, self-lock pin overcomes self-locking spring
Elastic force is inserted into the groove, and at this time rotation manual lock construction, just can drive drill bit to rotate together, realize the dismounting of drill bit,
It is very convenient without special tool.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Fig. 2 for Fig. 1 along the sectional view of A-A.
Schematic diagram when Fig. 3 is dismounting.
Specific embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
Referring to Fig. 1 and Fig. 3, a kind of electric drill with manual lock, including drill bit 1, the drill bit 1 is fixed on drill chuck 2,
Manual lock construction 3 is further included, the manual lock construction 3 is included from lock nut 31, self-lock pin 32, locking spring 33 and self-locking block 34,
The end that the self-lock pin 32 is fixed on from lock nut 31 is provided with through-hole 341, the self-lock pin 42 on the self-locking block 34
It is inserted into the through-hole 341, the locking spring 33 is sleeved on the self-lock pin 32, the both ends difference position of the locking spring 33
It is in contact from lock nut 31 and the self-locking block 34 with described, is provided at the position opposite with the through-hole 341 on the drill bit 1
Groove 11.Screw 4 is further included, the spiral shell 4 follows closely the end for being fixed on the drill bit 1.
In use, self-lock pin under the action of locking spring, is detached from the groove, at this time drill bit can be freely rotated,
It when needing to dismantle drill bit, then can press from lock nut, self-lock pin overcomes the elastic force of self-locking spring to be inserted into the groove, at this moment
Rotation manual lock construction is waited, just drill bit can be driven to rotate together, realize the dismounting of drill bit, it is very convenient without special tool.
