Cutting tool safety and labor saving mechanism

The invention relates to the technical field of a shearing tool, in particular to a safety and labor saving mechanism for a shearing tool for shearing a plate-shaped material.

Generally, plate-like materials such as woodwork or melamine plates are often cut using a specific cutting tool, whereby the appearance of the plate-like material has a desired angle. The traditional shearing tool consists of a hand-cutting body, an angled jaw and an angle-adjusting base, and is formed by wearing a plurality of riveting elements and locking elements. For example, the improved structure of the scissors disclosed in Taiwan Patent No. 595534.

Further, Taiwan Patent No. M241201 discloses an improved structure for special shearing, which is composed of an upper grip, a lower grip, a blade, an anvil and a fastener. The upper and lower grips of the prior patent are clamped by a pivot point and cooperate with a movable pivoting mechanism, whereby the anvil and the blade have a displacement-producing effect during use, thereby enhancing shearing. The effort of the trim is smooth and smooth.

Although the shearing tool disclosed in the above patents can effectively shear the plate material, when the thick plate material is sheared, the hand will be continuously pressed and the arm is changed. The fatigue is generated, so the pressing action is not once in place. In other words, the operator needs to gradually press the cutting tool in order to gradually cut the plate material apart. In the operation process, the operator needs to rest to eliminate or reduce the fatigue of the hand. However, there is no positioning mechanism between the two grips of the conventional cutting tool, so the cutting tool cannot be temporarily stopped on the workpiece. When the operator re-operates the cutting action, it is necessary to align the previous incision on the plate material and restart Pressing the blade into the slit has the disadvantage of being laborious and inconvenient, and also causes a problem that the shearing surface is not beautiful.

Secondly, even if the friction between the plate material and the blade can be utilized, the shearing tool can be temporarily stopped on the plate material, but the shearing tool is easily shaken off, and there is no positioning mechanism between the two grips. Therefore, the blade of the cutting tool is likely to expose the blade portion, which may cause injury to the operator or the surrounding workers.

In view of this, the inventors have in-depth discussions on the safety and laborious problems faced by conventional cutting tools, and have been researching and improving the existing cutting tools for many years, and have been researching and improving the existing cutting tools. The trial has finally succeeded in developing a safety and labor-saving mechanism for cutting tools, in order to overcome the inconvenience and trouble caused by the inability to cut at one time.

Therefore, the main object of the present invention is to provide an effortless labor saving mechanism for a cutting tool, which has the ability to gradually position the cutting tool during use, so that the operation can be rested to eliminate or reduce the hand. Fatigue, for the operator to achieve labor-saving operation.

Secondly, another main object of the present invention is to provide a safety and labor-saving mechanism for a shearing tool, which can be positioned during the cutting process or during the folding process, thereby avoiding the arbitrarily opening of the cutting edge and improving the safety of use. .

Still another object of the present invention is to provide a shearing tool safety and labor saving mechanism which has the ability to utilize a closed positioning in which the cutting tool can be directly released in a pulling manner, thereby greatly improving the convenience of the operation.

In order to achieve the above object and effect, the cutting tool disclosed in the present invention comprises: a cutting body, wherein a first handle is alternately pivotally coupled to a second handle, so that the first and second grips form a relative grip. a holding section and a clamping section, wherein the clamping section of the second grip is configured with a blade corresponding to the first grip clamping section; an anvil is disposed in the clamping section of the first grip, and the anvil a seat opposite the blade; An angled card is disposed on the surface of the cutting body, and the two ends of the angle locking piece are respectively locked with a first locking component and the second locking component is clamped to the first handle And the holding section, and secondly, the same outer edge of the angle clamping piece has a continuous series of toothed portions and an angle of the latching recess; a positioning key is elastically swingably mounted on the first handle, the positioning key Positioned on the side of the overlapping release pad and the angle card, and selectively corresponding to the card tooth and the angle of the card slot; a release paddle is disposed at the angle of the card The surface of the release pad is pivoted at the first locking component, and the other end is formed with a switching slot for the second locking component to pass. The switching slot has a positioning key that does not deviate from the latching portion. And an operating position of the angle of the recessed space and a release position for disengaging the positioning key from the engaging portion and the angle of the recess.

Therefore, through the specific implementation of the above technical means, the cutting tool of the present invention is more effective than the existing one in terms of "saving effect, safety, and ease of operation".
