Fixed pliers

The present invention relates to a hand tool, and more particularly to an innovative structural type designer of a fixed pliers in which the grip portion of the movable handle has an integrally stamped non-slip concave flange portion.

According to the fixed clamp of this creation, the industry is also generally called the universal clamp. Because it has a very strong and strong clamping force, and has a fairly fast and easy to operate release, it has been a kind of Widely known and widely used clamping tools.

The fixed pliers are quite simple in terms of structural planes, and are usually composed of main components such as fixed cymbals, movable cymbals, fixed shanks, movable shanks, adjusting bolts, tension springs, connecting rods, and release levers; There is no significant change in the principle of actuation and the basic main architectural form. However, the fixed clamp has found in its extensive experience that its main structural part is practical, but there are still some problems in the local part of its structure. To be improved, for example, the creator found in the long-term experience that the movable handle grip section of the conventional fixed clamp is usually made into a convex curved surface type, although this type is also considered in design. The stability and the anti-slip effect of the hand grip, but the actual use found that the effect is not good, because the activity 锷 is usually made of metal material, the surface will be plated, so the hand feels slippery when holding It is obvious that at this time, the movable handle holding section which is formed into a convex curved surface shape is difficult to provide a better sliding-sliding positioning function of the gripped human hand finger, thus causing During the process of holding the fixed clamp and during the clamping process of the movable handle, the gripping finger portion tends to slip, and even the hand is removed, resulting in safe use. Worrying, and the fixed clamp is usually composed of metal as a whole component. It is a heavy hand tool. If it hits the person's body when it is dropped, it will cause serious injury. If it is heavy, it will damage the environment. Goods are also prone to loss of property.

At the end of the investigation, although there is also a structure in the industry that re-covers or sets a slip-slip bushing on the outside of the movable grip holding section of the fixed pliers, the function of enhancing the slip-holding effect of the movable handle is achieved. The anti-slip bushing is usually made of rubber or foam material. However, although the conventional structural design can enhance the sliding effect of the movable handle, the durability is a big problem. The anti-slip bushing adopts a covering or a sleeve type, and after a period of use, since the rubber or the foaming material is not a rigid material, it is inevitable that embrittlement, cracking, peeling, and the like may start due to various factors. Problems such as thickening, and once such problems occur, because the industry usually does not sell replacements that provide the anti-slip bushings, the problem that the integral fixing pliers has to be discarded and discarded will result in poor durability of the product. Short-lived, wasteful resources and other shortcomings.
