Example 2
As shown in fig. 9, unlike embodiment 1, the first connecting arm 500 is provided with a first plane 530 facing away from the second connecting arm 600 at the bent position; a second plane 540 facing the second connecting arm 600 is arranged at the bent position of the first connecting arm 500; a third plane 630 facing away from the first connecting arm 500 is arranged at the bent position of the second connecting arm 600; the bent portion of the second connecting arm 600 is provided with a fourth plane 640 facing away from the first connecting arm 500.
When the first and second connection arms 500 and 600 are compressed by the forceps, the jaws of the forceps can be held on the first and third planes 530 and 630, and the jaws can be in contact with the planes, so that the slippage of the jaws can be alleviated. Similarly, when the first connecting arm 500 and the second connecting arm 600 are expanded by the forceps, the forceps can be inserted between the first connecting arm 500 and the second connecting arm 600, and then the forceps heads are respectively abutted against the second plane 540 and the fourth plane 640, and the forceps heads are in contact with the planes, so that the slippage of the forceps heads can be relieved.
Also, in the present embodiment, it is also possible to provide a limiting structure similar to that of embodiment 1 on the first and second link arms 500 and 600 so as to limit the minimum value of compression and the maximum value of expansion of the first and second link arms 500 and 600.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
