Problems solved by technology

[0004] For the auto-retract feature to be useful, the spring between the jaws must be strong enough to retract the jaws apart without being so strong that repeated and / or prolonged clamping becomes difficult or uncomfortable for the practitioner

Embodiment Construction

[0036] The clamp 20 consists of four main components, including: figure 1 and figure 2 A first arm 30 referred to herein as a first bottom jaw 30 shown in ; figure 1 and image 3 Shown in is called the second arm of the second top clamp 50; figure 1 and Figure 5 The helical coil spring 90 shown in the helical coil spring 90 biases the two pliers 30 and 50 to pivot apart into an unclamped retracted state; and figure 1 and Figure 4 The bolts 80 that hold the parts together are shown in .

[0037] The clamp 20 is not limited to only the above four components. Additional elements may be provided on the pliers to perform additional functions, for example, mechanically holding the jaws together without squeezing the handles together by hand.

[0038] The first pliers 30 include a first graspable handle 32 towards one end of the pliers. The second pliers 50 includes a second graspable handle 52 at the same end as the handle 32 of the first pliers.

[0039]The first forcep...

Abstract

A pliers having opposing pivoting pliers engaged by connectors and jaws retractable under the action of coil springs in the internal chambers of the connectors of the two pliers. When the pliers and their jaws are retracted, a channel that opens out from the spring cavity to the outer periphery of the first connector and in the space between the two jaws of the two pliers allows cleaning material to enter the jaws of the pliers. internal. The jaws are shaped and the passage into the interior of the jaws is positioned and shaped such that when the jaws are clamped and the jaws face each other, the passage into the interior of the jaws is blocked by at least one jaw.

Description

technical field [0001] The present invention relates to pliers, and more particularly to automatic retraction features of pliers. The forceps are particularly suitable for dental forceps, which can be used by a dentist during normal treatment. However, a clamp of this configuration may be used in other applications for grasping objects. Background technique [0002] Pliers typically include two arms or two separate jaws, each jaw having a respective gripping surface towards one end of each jaw; and a grasping handle at the other end of the jaws. a pivotal connection between the pliers, located between the jaws of the pliers and the gripping handle, enables the user to squeeze the handles together, which moves the jaws at the other side of the pivotal connection together, The jaws or gripping surfaces of the pliers thereby grip on teeth or other objects in the oral cavity or on any other object that the pliers will grasp. Typically, the jaws of the pliers are manually move...
