The forceps are reasonable in structure, particularly the clamping sections and the lengthening sections are connected firmly, thus the service life of the forceps is prolonged, the lengthening sections and the fixed sections can be connected firmly, and the mounting is convenient to carry out.
Description
Technical field
The utility model relates to a kind of medical equipment, is specifically related to a kind of tweezers that can change very easily tweezers head.
Background technology
Conventional tweezers are all integrated structure substantially at present, and this forceps constructions is simple, practicality, and in concrete use, owing to being one-body molded, therefore, in the time that tweezers head damages, whole tweezers have just been scrapped substantially, have caused waste.In the concrete application practice of medical science, need to use different tweezers for different experiment materials in addition, such as the thing of clamping pocket-handkerchief and strip, the dynamics of using is different, therefore, will adopt the tweezers of different tweezers heads, such replacing back and forth inconvenience very.
Although now had the tweezers that can change tweezers head, tweezers head is connected with jig arm, firm not, easily damage.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art and provides a kind of structure more reasonable, changes tweezers for convenience on tweezers first watch.
The purpose of this utility model is achieved in that
A kind of tweezers, comprise two jig arm, and each described jig arm forms by a canned paragraph, a lengthening section and a gripping section, and one end of described lengthening section is flexibly connected with canned paragraph, and the other end of described lengthening section is flexibly connected with gripping section.
Based on the above, described canned paragraph end is provided with an inserting groove, and this inserting groove is made up of open slot part and semi-open slot part, between described open slot part and semi-open slot part, is interconnected; Described lengthening section one end is provided with a plug corresponding with inserting groove, described plug is made up of plug one and plug two, described plug two is arranged on plug one end, described plug one plug-in mounting corresponding to open slot part, described plug two plug-in mounting corresponding to semi-open slot part.
Based on the above, the other end of described lengthening section is provided with a groove shape body, it is semicircular elongated slot that two sides of described groove shape body are provided with cross section, two described elongated slots are all parallel to groove shape body bottom surface, described gripping section end is provided with a plug one corresponding with groove shape body, the two sides of described plug one are provided with the strip projection of semicylinder structure, and described semi-cylindrical strip projection is the semicircular formation plug-in mounting that grows grass with cross section.
Based on the above, the length of described plug one is less than the degree of depth of groove shape body.
Based on the above, described strip projection is less than the distance of elongated slot to groove shape body bottom surface to the spacing of plug one end.
The utlity model has following advantage:
Structure of the present utility model is more reasonable, and especially gripping section is more firm with being connected of lengthening section, has increased the service life of tweezers, and lengthening section is also more firm with being connected of canned paragraph, installs also more convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of disassembled form of the present utility model.
Fig. 3 is the enlarged drawing of A part.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model will be further described.
As shown in Figure 1, 2, 3, a kind of tweezers, comprise two jig arm 1, and each described jig arm 1 forms by a canned paragraph 2, a lengthening section 3 and a gripping section 4, one end of described lengthening section 3 is flexibly connected with canned paragraph 2, and the other end of described lengthening section 3 is flexibly connected with gripping section 4.
Based on the above, described canned paragraph 2 ends are provided with an inserting groove 5, and this inserting groove 5 is made up of open slot part 5.1 and semi-open slot part 5.2, between described open slot part 5.1 and semi-open slot part 5.2, is interconnected, described lengthening section 3 one end are provided with a plug 6 corresponding with inserting groove 5, described plug 6 is made up of plug 1 and plug 2 6.2, described plug 2 6.2 is arranged on plug one 6.1 ends, described plug 1 plug-in mounting corresponding to open slot part 5.1, described plug 2 6.2 plug-in mounting corresponding to semi-open slot part 5.2, be installed with a block 5.3 in the position of semi-open slot part 5.2, when plug 6 plug-in mountings are to inserting groove 5 position time, just in time block 5.3 can stop that lengthening section 3 comes off, open slot part 5.1 sides are vertical plane structure in addition, the back side of plug 1 is also vertical plane structure simultaneously, make like this plug 1 corresponding with the vertical plane structure of open slot part 5.1, buckle is carried out to lengthening section in the side of the vertical plane structure of block 5.3 and open slot 5.1 simultaneously, realize not coming off of lengthening section.
In addition, described block 5.3 ends are oblique face structure, are convenient to like this installation of lengthening section 3 and canned paragraph 2, simultaneously after lengthening 3 and canned paragraph 2 install, can ensure can, due to excesssive gap, not connect result insecure or that rock back and forth and produce between lengthening section 3 and canned paragraph 2.
Based on the above, the other end of described lengthening section 3 is provided with a groove shape body 7, this groove shape body 7 is an open slot structure, the bottom surface of groove shape body 7 is plane, it is semicircular elongated slot 8 that two sides of described groove shape body 7 are provided with cross section, two described elongated slots 8 are all parallel to groove shape body 7 bottom surfaces, two grow grass and 8 are oppositely arranged, described gripping section 4 ends are provided with a plug one 9 corresponding with groove shape body 7, the two sides of described plug 1 are provided with the strip projection 10 of semicylinder structure, described semi-cylindrical strip projection 10 is that semicircular elongated slot 8 forms plug-in mounting with cross section, the cross section structure of strip projection 10 is corresponding with the cross section structure of semicircular elongated slot 8.
Based on the above, the length of described plug 1 is less than the degree of depth of groove shape body 7.
