Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but should be noted that; these embodiments are not limitation of the present invention; those of ordinary skill in the art are according to these embodiment institute work energy, method or structural equivalent transformations or substitute, and all belong within protection scope of the present invention.
Expression position described in the present invention and the word in direction are all using exercises on apparatus author as reference, and be near-end near one end of operator, the one end away from operator is far-end.
As shown in Figure 1 and Figure 2, the Linear seam cutting device lower clamp 10 that comprises clamp and coordinate with clamp on this 30.
This lower closed handle 20 comprises two sidewall 201a, 201b be oppositely arranged, and connects the diapire 203 of this two side.Wherein, each sidewall 201a, 201b include connecting portion 2011 and grip part 2012, and this connecting portion 2011 and grip part 2012 are formed with the first angle α.And this connecting portion 2011 is pivotally connected to described lower clamp 10.Described Linear seam cutting device also comprises shell fragment 50, and described shell fragment 50 one end is fixedly connected with the diapire 203 of described lower closed handle 20, and the other end against the diapire 103 of described lower clamp 10, and can slide along described diapire 103.By arranging this shell fragment 50, being make this lower closed handle 20 when leaving this lower clamp direction and opening, power-assisted effect can be played.
Preferably, on this, clamp 30 is connected with closed handle 40, on this, clamp 30 is removably connected by latching device with lower closed handle 20, wherein, this latching device comprises the lock pin 303 being arranged at described upper clamp 30 and a pair locked groove 2013 be arranged in described lower closed handle, and preferably, this pair locked groove is arranged on two connecting portions 2011 respectively, locked groove 2013 can hold lock pin 303 and within it rotate, to make can mutually swingingly arrange between upper clamp 30 and lower clamp 10.
As shown in Figure 1 to Figure 3, described lower clamp 10 comprises two sidewall 101a, 101b and the diapire 103 being connected described sidewall, described sidewall and diapire composition receiving space, can at this lower clamp far-end collecting nail bin or nail anvil, the two side 101a of described lower clamp 10, two stopper section 105a are also respectively arranged with outside 101b, 105b, this stopper section 105a, 105b can control the open angle between lower closed handle 20 and lower clamp, lower closed handle can not excessively be opened, make described shell fragment keep with the diapire of described lower clamp against, and between angle remain acute angle.To keep the stability connected between lower clamp and lower closed handle.Described two stopper section 105a, 105b are disposed adjacent with nail bin or nail anvil, and relative to described nail bin or the nail anvil near-end closer to described Linear seam cutting device, and the centrage of this two stopper section 105a, 105b is located along the same line.Preferably, this two stopper section 105a, 105b is the integrated boss of lower clamp 10 with this.When connecting portion 2011 is against described stopper section 105a, 105b, lock pin just departs from locked groove 2013, and the open angle of the relatively described lower clamp of described lower closed handle 20 is maximum, and two stopper sections 105a, 105b can stablize and prop up connecting portion 2011.
In addition, as shown in Figure 2, when described connecting portion 2011 is against described stopper section 105a, 105b, the angle between the diapire of described shell fragment and described lower clamp is the second angle β.In an embodiment of the present invention, this second angle β is less than described first angle α.Described grip part 2012 is also provided with accommodation section 205a, 205b of mating with described stopper section 105a, 105b, instantly, when closed handle 20 diapire 2013 is parallel with lower clamp 10 diapire, described stopper section 105a, 105b are contained in described accommodation section 205a, 205b.
Linear seam cutting device of the present invention by being provided with two symmetrically arranged stopper sections on clamp, apparatus is caused normally to use to avoid lower closed handle open angle excessive, two stopper sections more stably can control the open angle of lower closed handle, make the use of this Linear seam cutting device more convenient.And the open angle of lower close handles is controlled by paired stopper section, be not easy to lose efficacy, apparatus stability in the large is higher.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or basic feature, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
