Abstract
The utility model relates to labor-saving tweezers convenient to use. The labor-saving tweezers convenient to use comprise a labor-saving structure. The labor-saving structure comprises a rotary shaft and a holding handle, wherein one end of the rotary shaft is anchored in the middle of one tweezers arm, the other end of the rotary shaft penetrates through a hole in the middle of the other opposite tweezers arm and is connected with the holding handle, and a protrusion is arranged at the front end, connected with the rotary shaft, of the holding handle. The labor-saving tweezers convenient to use have the advantages during the long time when the tweezers are used, the labor-saving structure similar to nail scissors is added, the lever principle is adopted, the purpose of saving labor is achieved, experiment operation is convenient, finger fatigue is reduced, experiment efficiency is improved, and the body health of a user is protected.
Description
Technical field
The utility model relates to a kind of convenient and strength-saving tweezers.
Background technology
Tweezers are conventional use instruments in each experiment, especially in some operation, need to use for a long time tweezers, and test for a long time tweezers, easily cause finger tired, operating efficiency declines, especially in some accurate operation experiment, easily make mistakes, cause irremediable loss.And, use tweezers overlong time, can cause pointing stiff, when serious, may suffer from stuck-finger.Therefore, for the worker of long-time use tweezers, a kind of can be laborsaving and tweezers simply and easily, not only can increase work efficiency, and can protect self health, the utility model arises at the historic moment.
Utility model content
The purpose of this utility model is to provide a kind of convenient and strength-saving tweezers, has added the labor-saving structure of similar nail clipper in tweezers middle section, utilizes lever principle, reaches labour-saving object, facilitates experimental implementation, improves conventional efficient.
According to force-saving tweezer of the present utility model, it comprises labor-saving structure, described labor-saving structure comprises rotating shaft D and lever C, one end of described rotating shaft is anchored to the middle part of a tweezer arm, the other end is connected with the front end of described lever C through the hole at another tweezer arm middle part, described lever has projection at the link of nearly rotating shaft, and therefore described rotating shaft and described lever have formed the labor-saving structure of similar nail clipper in tweezers middle section.
According to convenient and strength-saving tweezers of the present utility model, described lever is fixed on rotating shaft near the end of tweezers band hole side, can, along the axle vertical plane rotation of rotating shaft together with rotating shaft, also can fasten with tweezers; And lever front end tool projection and rear end perk, when pressing rear end, front end protrusion presses to tweezers one side, makes tweezers clamping.
Rotating shaft D is installed in tweezers stage casing, fixes with tweezers A side; Tweezers B side has hole, can allow rotating shaft D completely by and contactless.And rotating shaft D can not be along the axially-movable of rotating shaft D, but can rotate.
Lever C can be along the axle vertical plane rotation of rotating shaft D together with rotating shaft D, and lever C front end tool projection, is similar to the fulcrum in lever, and when pressing C rear end, front end protrusion presses to tweezers, makes two arm clampings of tweezers, convenient and strength-saving while making experimental implementation.Lever C also pulls to tweezer arm side after capable of rotating 180 deg, fastens with tweezer arm side, places minimizing and take up room also more attractive in appearance after fastening.
The utility model has the advantage of: at long tweezers, between the operating period, the labor-saving structure of the similar nail clipper newly adding, brings into play lever principle; reach labour-saving object, facilitate experimental implementation, reduce finger tired; improve conventional efficient, and protect that user's is healthy.

The specific embodiment
Embodiment 1
As Figure 1-3, according to force-saving tweezer of the present utility model, it comprises labor-saving structure, described labor-saving structure comprises rotating shaft D and lever C, one end of described rotating shaft is anchored to the middle part of a tweezer arm A, and the other end is the tweezer arm B with hole through another middle part, is connected with described lever C, described lever C has projection E at nearly rotating shaft link, and therefore described rotating shaft D and described lever C have formed the labor-saving structure of similar nail clipper in tweezers middle section.
According to convenient and strength-saving tweezers of the present utility model, described lever C is fixed on rotating shaft D near the end of tweezers band hole side, can, along the axle vertical plane rotation of rotating shaft D together with rotating shaft D, also can fasten with tweezers; And lever front end tool projection and rear end perk, when pressing rear end, front end protrusion presses to tweezers one side, makes tweezers clamping.
Lever C can be along the axle vertical plane rotation of rotating shaft D together with rotating shaft D, and lever C front end tool projection, is similar to the fulcrum in lever, and when pressing C rear end, front end protrusion presses to tweezers, makes two arm clampings of tweezers, convenient and strength-saving while making experimental implementation.Lever C also pulls to tweezer arm side after capable of rotating 180 deg, fastens with tweezer arm side, and the rear placement minimizing of fastening takes up room also more attractive in appearance, convenient and strength-saving while making experimental implementation, reduces and points fatigue, raising conventional efficient.
The tweezers that contrast after common tweezers and improvement are organized choosing embryo and shifting callus work in cultivation, carry out the analysis of experimental data as table 1
Table 1
Form by above can it is evident that: compared with the tweezers after common tweezers improvement, improved significantly conventional efficient.
