Problems solved by technology

Although the blade portion made in this way can avoid breakage and cracks, it is easy to damage the blade portion 72 from the welded spot 74 due to poor welding technology or the constant pressure of the blade portion 72 . And then make this blade portion 72 split into two parts, make the utilization rate of this pliers 7 not high
[0005] Furthermore, after the blade portion 72 has been used for a period of time, the blade portion 72 will lose its ability to cut due to wear and tear. At this time, the pliers 7 will not have the effect of cutting, and only the entire pliers 7 will be replaced. Replacing pliers 7 would increase costs
[0006] In summary, existing hand tools are inconvenient in use, and there is a need for improvement.

Embodiment Construction

[0037] Please refer to Fig. 1 to Fig. 15, the hand tool of the embodiment of the present invention is a needle-nose pliers as an example, as shown in Fig. 1, the hand tool includes: two handles 1, the two handles 1 are pivotally connected to each other , one end of each handle 1 has an action part 11 for clamping objects, and the other end of each handle 1 has a grip part 12 for holding, and each handle 1 has a pivot joint A pivoting portion 13, each pivoting portion 13 has a pivoting hole 131 in the middle of each pivoting portion 13, for a shaft rod 14 to penetrate and pivot, so that the two handles 1 are pivoted to each other, so that the grip of the two handles 1 Part 13 drives the two action parts 11 to open and close for clamping workpieces. An accommodating groove 111 is respectively provided on the opposite inner side of each action part 11 near the pivot joint part 13 . The blade portion 2 has at least one shearing section 21 and a fastening hole 22, and a fastening ...

Abstract

A manual tool with exchangeable cutter edge part is composed of a pair of pivoted handles with an extended action part respectively, which has a cutting edge part acceptable recess, an exchangeable cutting edge part with shearing segment and fixing hole, and a fixing element for fixing the cutting edge part in its recess.

Description

technical field [0001] The invention relates to a hand tool with a removable blade. Background technique [0002] As shown in Figure 16, it is a common hand tool, the hand tool is a pliers 6, the pliers 6 is formed by two handles 61 pivoted to each other, each handle 61 has a pivoting portion 62 at the front end , for the two handles 61 to be pivotally connected to each other, and each handle 61 is respectively extended forward by a pincer portion 63 from the pivot portion 62, and each pincer portion 63 is provided with a blade portion 64 near the inner side of the pivot portion 62. Cutting is performed by the opposing blade portions 64 . [0003] Since the blade portion 64 and the jaw portion 63 are integrally formed by high-frequency operation, and a high-frequency partial treatment is applied to the blade portion 64, the strength and hardness of the blade portion 64 processed by the second high-frequency processing are equal. Higher, in use for a period of time, the tou...
