Description
Technical field
The present invention relates to a kind of hand-held tool that changes blade.
Background technology
As shown in figure 16, it is general common hand-held tool, this hand-held tool is a pliers 6, this pliers 6 is to be articulated mutually by two levers 61 to form, and the front end of each lever 61 has an articulated section 62 respectively, articulates mutually for two levers 61, and each lever 61 extends a pincers portion 63 forward by this articulated section 62 respectively, be provided with a blade 64 between the relative inner of each pincers portion 63 nearly articulated section 62, by this relative blade 64, to shear.
Because this blade 64 is to adopt high frequency operation one-body molded with pincers portion 63, and impose the Local treatment of a high frequency again in this blade 64, but blade 64 through the processing of secondary high frequency, its intensity and hardness are all higher, using a period of time, because of the hardness height makes the toughness of this blade 64 and ductility relatively poor, easily produce fragmentation and crack.
For avoiding repeating to implement high frequency operation, cause this blade 64 to produce fragmentation and crack, so another kind of pliers 7 occurs, as shown in figure 17, it is to be respectively equipped with a caulking groove 711 in each pincers portion 71, and for blade 72 installings, and this blade 72 is to make separately, again after high frequency is handled, blade 72 can be fixed in this caulking groove 711 after being about to blade 72 and making through welding.The blade that this kind mode is made, though can avoid fragmentation and crack, but the relation normal bad or this blade 72 constantly bears pressure because of solder technology, make this blade 72 be easy to produce destruction from the pad 74 that is welded, and then make this blade 72 split into two parts, make that the utilization rate of this pliers 7 is not high.
Moreover this blade 72 can make the ability of these blade 72 forfeiture shearings because of loss in use for some time, and at this moment, this pliers 7 will not have the effect of shearing, have only whole the pliers 7 of replacing, can raise the cost but change pliers 7.
In sum, existing hand-held tool, in the use have inconvenience more, and in addition improved necessity is arranged in fact.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcome the defective that existing hand-held tool exists, and a kind of hand-held tool of changed blade newly is provided, it can make this blade have the function of shearing and changeing fast, and have good practicality, and reduce the cost that hand-held tool is changed.
