Figures 5-9 are schematic views of other embodiments of the stud.

As shown in Figures 1 through 3, the figure of the preferred embodiment of the clamp 10 is shown in multiple angles. In the figure, the same number is marked, belonging to the same part or component of the clamp 10.

The tongs 10 are connected by a body 20 to a movable arm 30, a movable handle 33, an elastic member 40, a toggle link 50, a stud 60 and two oscillating members 70, 80. , a clamp effect on an object (not shown).

Specifically, the body 20 is composed of a handle 21 and a fixed arm 22. Both the grip 21 and the movable handle 33 are long U-shaped bodies. The handle 21 has a threaded portion 24 and a hook portion 25. The screwing portion 24 is a tube having an internal thread and passes through the U-shaped internal space of the grip 21. The hook portion 25 is integrally formed with the wall of the grip 21 and is bent toward the inner space of the grip 21. A trigger 34 is placed into the U-shaped interior of the movable handle 33, which are joined together by a rivet-like coupling member 14 such that the trigger 34 flexibly moves relative to the movable handle 33 like a seesaw.

The fixed arm 22 and the movable arm 30 are both arched bodies. One end of the fixing arm 22 is fixed to the handle 21 away from the screw portion 24, and the other end forms a fixing 颚 23, so that the fixing 颚 23 and the screwing portion 24 are located at both ends of the body 20. The movable arm 30 has a movable jaw 31 and a hole 32. The movable jaw 31 is at one of the two ends of the movable arm 30, and the movable arm 30 is placed at the other end into the U-shaped inner space of the grip 21, and the two are joined by the other joint members 11. Centered on the joint member 11, the movable arm 30 is coupled with the movable jaw 31 in a deployed position. Set to rotate with a closed position. The movable arm 30 and the movable handle 33 are joined by the other coupling member 12, and the movable handle 33 and the grip 21 are on both sides of the hole 32.

The deployed position referred to herein refers to the position at which the movable jaw 31 leaves the fixed jaw 23. As for the closed position, it refers to the position of the movable jaw 31 near the fixed jaw 23.

In the present embodiment, the elastic member 40 is a spring such as a tension spring. The two ends of the tension spring respectively hook the hook portion 25 and the hole 32 to provide the force required for the movable arm 30 to move relative to the handle 21.

The toggle link 50 has a projection 52. When the two ends of the toggle link 50 are respectively inserted into the U-shaped grip 21 and the movable handle 33, the movable handle 33 and the toggle link 50 are connected by other coupling members 13 to support the toggle link 50 flexibly. Turn.

The stud 60 is provided with an external thread that is coupled to the screw portion 24, and further penetrates into the inner space of the grip 21 until the inner end 61 of the stud 60 (see FIG. 5) and the toggle link 50 enter the inside of the grip 21. When the parts of the space are in contact with each other, the angle at which the movable arm 30 is extended with the fixed arm 22 is determined, and most of the objects or workpieces (such as a circular tube or a rod body) can be clamped, which is more suitable for most items than the conventional clamp.

The outer end of the stud 60 has a hanging portion 62. The hanging portion 62 is a circular ring. The ring is exposed outside the grip 21 to facilitate lifting the entire pliers 10 in the construction site or suspending the entire pliers 10. On the wall, it not only facilitates the finishing of tools, but also shortens the time of searching.

When the movable jaw 31 is held in the deployed position relative to the fixed jaw 23, the toggle link 50 is moved away from the handle 21 against the movable handle 33, driving the movable arm 30 away from the fixed arm 22. Conversely, when the movable jaw 31 is held in the closed position relative to the fixed jaw 23, the toggle link 50 is mostly obscured by the grip 21 and the movable handle 33, and the associated projection 52 presses a contact portion 35 formed on the trigger 34 into the movable portion. Inside the handle 33, the end of the trigger 34 is displaced to the outside of the movable handle 33.

Therefore, the end of the trigger 34 is forced into the movable handle 33, and the contact portion 35 The projection 52 is pushed open, causing the movable jaw 31 to return from the closed position to the deployed position relative to the fixed jaw 23.

In addition, the swinging members 70, 80 are pivotally connected to the fixed jaws 23 and the movable jaws 31, respectively. As shown in Fig. 4, each of the oscillating members 70, 80 has two pairs of folded portions 74, 75, 84, 85, which connect the one panel 73, 83 and the two pivots 71, 72 or 81, 82 together. These pivotal ears 71, 72, 81, 82 are arranged side by side on either the fixed jaw 23 or the movable jaw 31, and are joined together by other coupling members 15, 16 to support the jaw panels 73, 83 to move back and forth relative to the fixed arm 22 or the movable arm 30. Therefore, the oscillating members 70, 80 help the fixed cymbal 23 and the movable cymbal 31 at different angles of the caliper object, and are suitable for general platform or article appearance.

In some embodiments, the oscillating members 70, 80 have no folds. As long as the pivots 71, 72, 81, 82 are securely (e.g., welded) to the back of the jaw panels 73, 83, they can also move back and forth relative to the fixed arm 22 or the movable arm 30.

Next, see Figures 5-9, which show different embodiments of the stud 60. The structure of the studs 60 is substantially the same, the difference is that the hanging portion may be an elliptical ring portion 621; or the angular ring portions 622, 624, such as one of a triangle and a hexagon; or a polygonal ring portion 623, 625, such as one of a square and a rectangle.
