The tool pliers uses the tension of the spring to act on the two arms, causing the pliers jaws to automatically open after a work process is completed without artificially pulling two arms. Thus the use is convenient and the work efficiency is increased.
Description
The utility model is that it is a basic hand tools indispensable in industry and the daily life about a kind of instrument pincers.
Instrument pincers are hand tools of using always, by the chela shape can be divided into diagonal cutting nippers, angle jaw tongs, patterns such as the pincers of answering back, nipper plier, pliers.Two chela rear ends fuse with a tong arm respectively, by to the tong arm application of force, make the chela closure and the nipper workpiece, after the one action state finishes chela are opened and just can enter duty for the second time.Existing instrument pincers all need draw back two arms at every turn artificially just can make chela open, troublesome poeration, and work efficiency is low.
The purpose of this utility model provides a kind of self-opening instrument pincers, and it need not to draw back two arms artificially, and can automatically open jaw, to increase work efficiency.
The utility model self-opening instrument pincers are made up of chela and tong arm, are provided with spring between two tong arms, and spring can be located at opening in the shelves between inboard, two arms upper end, and this spring can be that helical spring also can be a reed.Spring is compressed when clutching two tong arms, opens shelves and narrows down, and the chela closure is in running order; After the one action process is finished, as long as unclamp tong arm, stop the application of force, spring promptly resets, and two arms are backed down, and it is multiple wide to open shelves, and chela opens automatically.
As seen the utility model self-opening instrument can open chela automatically, need not to draw back two arms artificially, and is easy to use, also improved operating efficiency.
Below in conjunction with description of drawings embodiment of the present utility model.
Fig. 1 and Fig. 2 are equipped with helical spring the utility model example structure figure between two arms, Fig. 1 is the chela closure state, and Fig. 2 is the chela open configuration.
Fig. 3 is the example structure figure that reed is housed between two arms.
As shown in Figure 1, 2, 3, the utility model self-opening instrument pincers comprise between two chelas 1 and the inboard, tong arm 4, two tong arms upper end and for opening between grade 3, two arms spring 2 are housed, and wherein, Fig. 1,2 embodiment are helical spring, and Fig. 3 embodiment is a reed.
