Specific embodiment

Embodiment one, the present embodiment are a kind of integrated tweezers of sustainable replacement tweezer head.

Please refer to Fig. 1-Fig. 5, the integrated tweezers of sustainable replacement tweezer head comprising tweezer body 1, two it is multiple into part 2, it is several A tweezer head 3 and tweezers cap 4.

Tweezer body is hollow property structure, and respectively there is a symmetry convex guide rail 14 in front and back.

Tweezer body 1 includes left tweezer body 11, right nipper piece 12 and interconnecting piece 15；Left tweezer body 11 passes through interconnecting piece phase with right nipper piece 12 Even.

Left tweezer body 11 is provided with hat shape protection cap 13 with 12 initial part of right nipper piece；1 end of tweezer body is provided with multiple into part 2, it promotes button 21 to splice by sliding slot and tweezer body 1, return is realized by small spring 23 between button 21 and tweezer body 1 promoting, Button 21 is promoted to have around each one pushing ram 22 inside the hollow property of tweezer body 1, pushing ram terminus area becomes larger, and pushing ram is height Elastic material is made, by sliding the multiple advance filling for realizing tweezer head into part.

Tweezer head 3 is hollow property plastic material, has concave sliding slot 33 outside long tweezer head before tweezer head 3, has behind tweezer head 3 short Tweezer head outside concave sliding slot 34；Concave sliding slot 33,34 is mutually chimeric with the front and back convex guide rail 14 of tweezer body respectively, to realize Stability of the tweezer head 3 in tweezer body 1.

Tweezer head 3 has convex shape 31 and tweezer head inside concave structure 32 outside tweezer head；Previous tweezer head 3 and the latter tweezer head 3 by slightly rotation counterclockwise rotation make it is the 31 of previous tweezer head mutual chimeric with the 31 of the latter tweezer head, to realize stabilization Connection；It can reach the separation of front and back tweezer head 3 by slightly rotating clockwise.

The working principle of the integrated tweezers that tweezer head can continuously be replaced of the present embodiment are as follows: usually, front and back tweezer head passes through tweezer Connection between son realizes and fixes that convex guide rail realizes that tweezer head exists in the concave structure and tweezers that the tweezer head connected passes through surface The intracorporal stabilization of tweezer；In use, referring to Fig. 3, tweezers cap is removed, by forward slip propulsion button, before promoting pushing ram End is contacted with tweezer head end, pushes tweezer head forward, and under the action of pushing ram, tweezer head passes through counterseal ring structure, and at tweezer body end Under the cooperation of end ring shape bulging structure 25, the fixation of tweezer head end is realized, while pushing ram is on earth, in the effect of small spring Under, latter tweezer head end is contacted and passed over, is ready to promote again, can realize clamping work with the tweezer head front exposed at this time； After use, sliding promotes button again, and used tweezer head protrudes further along, while latter tweezer head reaches previous tweezer head and makes It realizes the separation connected between the tweezer head of front and back by rotating clockwise previous tweezer head, exposes clean latter tweezer head in the position of used time It continues to use；After the intracorporal tweezer head use of tweezer, tweezer body is after disinfection, the hat shape protection cap of openable tweezer body initial part To add new tweezer head string, realization recycling；It is closed when without using tweezers Shi Keyong tweezers cap, is made convenient for next time With.

In summary, the integrated tweezers that can continuously replace tweezer head in the utility model, tweezer head 3 can be replaced continuously , do not need the disinfection cleaning operation such as immersion, calcination, the cross contamination being also possible to prevent between different samples, easy to operate, efficiency It is higher；The multiple use of tweezer head can be realized according to the tweezer head of the different identical unlike materials of purposes design principle.

, it is understood that the orientation of the instructions such as term "front", "rear", "left", "right", "horizontal", "inner", "outside" or Positional relationship is to be based on the orientation or positional relationship shown in the drawings, and is only that the present invention is described with simplified for ease of description, without Be instruction or imply signified device or element and must have a particular orientation, construct and operate for specific orientation, because without It can be interpreted as the limitation to present invention protection content.

Above specific embodiment is only the preferred embodiment of this creation, all at this not to limit this creation Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of creation should be included in the protection model of this creation Within enclosing.
