Easy to open clamp

The present invention relates to a hand tool, and more particularly to an easy-opening forceps.

As shown in FIG. 1 , a conventional clamp includes a handle 100 formed with a groove 101 , a pressing portion 200 disposed on the groove 101 , and a groove 101 and a pressing portion 200 . a pivoting lever 300, a switching lever 400 pivotally connected to the pressing portion 200, a first clamping portion 500 fixed to the handle portion 100, and a second clamping portion 600 connected to the pressing portion 200, the conversion The lever 400 has a reset end 401. The user can press the pressing portion 200 downward and bring the second clamping portion 600 toward the first clamping portion 500. The switching rod 400 and the lever 300 are mutually swayed to fix the rod 400. The position of the pressing portion 200 is fixed, and the second clamping portion 600 is fixed, and the first clamping portion 500 and the second clamping portion 600 jointly hold an object, and when the object to be clamped is to be loosened, the object is used. The resetting end 401 of the switching rod 400 can be pressed to release the switching rod 400 and the lever 300, and the second clamping portion 600 can be returned to the original position by a spring, and the pressing portion is driven. 200 returns to the position where it was not pressed.

However, since the surface of the reset end 401 of the conversion lever 400 is relatively smooth, it is more difficult to apply force when the user's finger presses the reset end 401, which is inconvenient to use.

Therefore, the object of the present invention is to provide a forceps that is easy to apply and that facilitates the reset.

Therefore, the new easy-opening clamp comprises a fixed handle, a movable handle, a movable block, a conversion block, a first chuck, a second chuck, and an adjusting member.

The fixed shank defines a long slot, and the fixed handle includes a front side and a rear side opposite to the front side.

The movable handle is movable relative to the fixed handle and includes a pressing portion.

The movable block is disposed on the long slot and one end of the movable block is pivotally connected to the bottom of the movable handle.

The conversion block includes a pivoting end pivotally connected to the bottom of the movable handle, and a pressing head end opposite to the pivoting end, the pressing head end protrudes from the pressing portion and has a rough surface, the rough surface has At least one recess.

The first chuck is fixed to the front side of the fixed handle.

One end of the second collet is coupled to the movable handle and is movable by the movable handle to move relative to the first collet.

The adjusting member is screwed to the rear side of the fixing handle, and the front end of the adjusting member is located in the long groove and abuts against the movable block

The utility model has the advantages that the rough surface of the pressing head end of the conversion block increases the frictional force when the user presses the finger, so that the user can easily apply the force when pressing, and the user can more easily press the pressing head end to make the second The collet returns to its original position.

As shown in FIG. 2 and FIG. 3, an embodiment of the presently-openable clamp comprises a fixed handle 1, a movable handle 2, a movable block 3, a conversion block 4, a first chuck 5, and a The second chuck 6, an adjusting member 7, and a spring 8.

The fixed shank 1 defines a long slot 11 and includes a front side 12 and a rear side 13 relative to the front side 12.

The movable handle 2 is movable relative to the fixed handle 1 and includes a pressing portion 21 and a notch 22.

The movable block 3 is disposed on the long slot 11 , and one end of the movable block 3 is pivotally connected to the bottom of the movable handle 2 .

Referring to FIG. 4, the conversion block 4 includes a pivoting end 41 pivotally connected to the bottom of the movable handle 2, and a pressing head end 42 opposite to the pivoting end 41. The pressing head end 42 passes through the gap. 22, protruding from the pressing portion 21, the pressing head end 42 has a rough surface 421, and a side convex portion 422 having a plurality of recessed portions 423 disposed at intervals, the side convex portion 422 is fixed toward the fixing portion The direction of the rear side 13 of the shank 1 is convex. In this embodiment, the recessed portions 423 extend laterally in the left and right directions, but are not limited thereto. The recessed portions 423 may also extend obliquely (see FIG. 5) or may extend obliquely in both left and right directions. Interlaced with each other (see Figure 6).

The first chuck 5 is fixed to the front side 12 of the fixed handle 1. The first chuck 5 includes a fixing rod portion 51 disposed on the long slot 11 and a clamping portion connected to the fixing rod portion 51. 52, the clamping portion 52 has two first clamping jaws 521. In the embodiment, each of the first clamping jaws 521 is generally C-shaped, but is not limited thereto.

One end of the second collet 6 is connected to the movable handle 1 and can be moved by the movable handle 1 to move relative to the first collet 5. The second collet 6 has a movably disposed on the long slot 11 The movable rod portion 61 has a clamping portion 62 connected to the movable rod portion 61, and the clamping portion 62 has two second clamping jaws 621.

As shown in Figures 7 and 8, the second collet 6 is movable relative to the first collet 5 between a clamped position and a released position when the second collet 6 is in the clamped position ( Referring to FIG. 7), the second jaws 621 abut against the first jaws 521, respectively. When the second jaws 6 are in the release position (see FIG. 8), the second jaws 621 are away from each other. The first jaws 521.

As shown in FIG. 2 and FIG. 3 , the adjusting member 7 is screwed to the rear side 13 of the fixing handle 1 . The front end of the adjusting member 7 is located in the long slot 11 and abuts against the movable block 3 .

The spring 8 is disposed between the fixed rod portion 51 of the first collet 5 and the movable rod portion 61 of the second collet 6.

When the user wants to grasp an object, the pressing portion 21 of the movable handle 1 can be pressed, so that the movable handle 2 drives the second collet 6 to move to the clamping position, and the movable handle 1 drives the conversion block 4 Causing the conversion block 4 and the movable block 3 to move relative to each other, and positioning the second chuck 6 in the clamping position, the user can move the position of the adjusting member 7 to change the movable block 3 Position to adjust the degree of clamping, when the user wants to return the second collet 6 from the clamping position to the releasing position, the pressing head end 42 of the conversion block 4 can be pressed with a finger to release the conversion block 4 In the turbulent relationship with the movable block 3, the second chuck 6 automatically moves to the release position due to the potential energy of the spring 8 returning, it is worth mentioning that the roughening of the head end 42 The recessed portion 423 of the surface 421 can increase the frictional force when the user presses. Further, when the user's finger presses the pressing head end 42 , the side convex portion 422 is first contacted, and the side convex portion 422 is located at the user's finger pressing. The force application area at the time, and because the area of the side convex portion 422 is small, the user can press In force, and the more relaxed the second chuck 6 Reply to the release position.

In summary, the new easy-opening clamp can make the chuck easier to return to the original position, so it can achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
