Specific embodiment
Embodiment one.The present embodiment is a kind of tweezers of replaceable tweezer head.
Refer to Fig. 1-Fig. 3, the tweezers of replaceable tweezer head, it includes 1, two locking members 2 of tweezer body and two tweezers first 3.
Tweezer body 1 includes left tweezer body 11, right nipper piece 12 and rivet 13；Left tweezer body 11 is cut with scissors with right nipper piece 12 by rivet 13
Connect.
Left tweezer body 11 and right nipper piece 12 are provided with the overall locking slot 14 in circular arc；The both sides of locking slot 14 are all provided with
Chute 15 is equipped with, the bottom of chute 15 is provided with oblique convex 16.
Locking member 2 is made up of elastomeric material, such as ABS plastic or spring steel etc..The both sides of locking member 2 be provided with
The guide rail 21 that chute 15 matches, the bottom of locking member 2 is provided with two barbs 23, and barb 23 is fixedly installed raised 22.
Tweezer first 3 is the hollow structure of one side opening.
Two locking members 2 are separately positioned in the locking slot 14 of left tweezer body 11, in the locking slot 14 of right nipper piece 12；Guide rail 21
Insertion chute 15 makes locking member 2 to be slided with respect to locking slot 14.
Two the four of locking member 2 barbs 23 are inserted and support two tweezers first 3, are separately fixed at two tweezers first 3 respectively
The bottom of left tweezer body 11, the bottom (i.e. tweezer first 3 is the state being locked) of right nipper piece 12.
The operation principle of the tweezers of the replaceable tweezer head of the present embodiment is：Usually, tweezer first 3 is the state being locked, this reality
The tweezers for applying the replaceable tweezer head of example can be used as traditional tweezers.
Refer to Fig. 4, it is necessary to when changing tweezer it is first 3 when (such as extract in the experiment of insect DNA, it is necessary to press from both sides other insect
When), locking member 2 is pushed down on, makes raised 22 tiltedly convex 16 to be supported, oblique convex 16 support raised 22 makes barb 23 that inside bullet to occur
Property deformation, from without supporting tweezer first 3, tweezer first 3 can be removed from locking member 2；Now tweezer first 3 is dismountable state.By tweezer first 3
After removing, pre-prepd (not contacted with clipped object product) tweezer first 3 is enclosed within locking member 2, pushes up locking member
2nd, raised 22 are made convex 16 not supported tiltedly, barb 23 recovers to support tweezer first 3 after shape, tweezer first 3 is fixed on the bottom of left tweezer body 11
Portion or the bottom of right nipper piece 12.
From the above, it is seen that the tweezer first 3 of the tweezers of the replaceable tweezer head of the present embodiment can be changed, it is not necessary to soak,
The operation of the head of calcination tweezers is also possible to prevent the DNA cross pollutions of different insects, and easy to operate, efficiency is higher.
Embodiment two.The present embodiment is a kind of tweezers of replaceable tweezer head.
Fig. 5 is referred to, the present embodiment is tweezer first 3 with the difference of embodiment one.
The shape of the section of the tweezer first 3 of the present embodiment is integrally triangular in shape.The present embodiment is applicable the less object of folder, convenient
Accurate operation.
The contraction spring 25 that the top of locking member 2 is also provided with lead column 24 and is enclosed within lead column 24；Left tweezer
Body 11 and right nipper piece 12 are provided with gathering sill 18；In the insertion gathering sill 18 of lead column 24, the contraction spring 25 of left tweezer body 11
Two ends be fixedly connected with locking member 2, left tweezer body 11 respectively；The two ends of the contraction spring 25 of right nipper piece 12 respectively with locking member 2,
Right nipper piece 12 is fixedly connected.After locking member 2 is pushed down on into the lower tweezer first 3 of dismounting, install other tweezers it is first 3 when, locking member 2 exists
It is automatically moved up under the pulling force of contraction spring 25, locks tweezer first 3, it is more convenient.
Button 26 is also provided with locking member 2.Locking member 2 can easily be moved by button 26.
Left tweezer body 11 and right nipper piece 12 are also provided with spring leaf 17.It is left when unclamping the tweezers of replaceable tweezer head
Tweezer body 11 and right nipper piece 12 are automatically separated under the elastic force effect of spring leaf 17, more convenient.
In sum, the tweezers of the replaceable tweezer head in the utility model, tweezer first 3 can be changed, it is not necessary to be soaked, calcination
The operation of the head of tweezers is also possible to prevent the DNA cross pollutions of different insects, and easy to operate, efficiency is higher；Folder can be applicable
Less object, facilitates accurate operation.
