The spring clip 209 of described first handle 200 is toward interior side bending distortion, and is provided with elasticity; The interior side of spring clip 209 is provided with rotating disk slot to make way 202, spring groove 206 and convex post slot to make way 207, and central point linearly distributes.
The convex post slot to make way 207 of described first handle 200 communicates with spring groove 206, and convex post slot to make way 207 is connected with step shaft hole 208.
Described screens 203, corner 204 are located at the interior side of first handle 200, and the degree of depth of screens 203 is greater than the degree of depth of rotating disk slot to make way 202
Described rotating disk slot to make way 202, screens 203, corner 204, spring groove 206 and convex post slot to make way 207 are located at the interior side of first handle 200; Wherein, rotating disk slot to make way 202, spring groove 206 and convex post slot to make way 207 are located in spring clip 209 and central point linearly distributes; The degree of depth of screens 203 is greater than the degree of depth of rotating disk slot to make way 207.
As shown in Figure 6, second handle 300 includes second handle front end 301, second handle rear end 302, the 2nd through hole 303, the 2nd interval trepanning 304, the 2nd stop bit nail 305 and the 2nd screw hole, interval 306.
As shown in Figure 7, described rotating disk 4 includes arc notch 41, screw hole 42, rotating shaft heavy hole 43, convex post 44.
As shown in Figure 8, described spring 5 includes outer side 51.
As shown in Figure 9, described step rotating shaft 3 includes screw hole 31, small stair 32, big step 33.
Such as Fig. 4, as shown in Figure 5, described spring 5 is arranged in spring groove 206, and rotating disk 4 is arranged in rotating disk slot to make way 202, and it is inner that the convex post 44 on rotating disk 4 is positioned at convex post slot to make way 207, and with outer side 51 Elastic Contact of spring 5.
The convex post slot to make way 207 of described first handle 200 is connected with step shaft hole 208, during installation, convex post 44 can move to from step shaft hole 208 and allow convex post slot to make way 207, screens 203 on first handle 200 limits the elasticity distortion scope of spring clip 209, spring clip 209 can be prevented to be out of shape transition and cause elastic failure.
The big step 33 of described step rotating shaft 3 is arranged in the step shaft hole 42 of rotating disk 4, the step end face of big step 33 is positioned at the heavy hole 43 of rotating shaft of rotating disk 4, small stair 32 is arranged in the step shaft hole 208 of first handle 200, and the step end face of small stair 32 contacts with the bottom surface of the rotating disk slot to make way 202 of first handle 200.
The two ends of described stop bit nail 2 are arranged in the first stop bit nail 212 and the 2nd stop bit nail 305 respectively.
The screw through-hole 31 of riveted joint screw 8 through first handle 200 and with step rotating shaft 3 is riveted tightly fixing. Described main shaft 9 is each passed through the 2nd through hole 303, operator through hole 101 and the first through hole 201, and tightens fixing by main shaft screw 7. The two ends that described interval overlaps 12 are arranged on the first interval trepanning 213 and the 2nd interval trepanning 304 respectively, and tighten fixing by interval screw 10.
Further, the both sides of described convex post slot to make way 207 limit the mobile scope of convex post 44, thus limit the rotation scope of rotating disk 4. When the convex post 44 on rotating disk 4 moves to the mid-way of convex post slot to make way 207, the spring resistance that convex post 44 is subject to is maximum; When convex post 44 touches the both sides of convex post slot to make way 207, the spring resistance that convex post 44 is subject to is minimum, and rotating disk 4 is stablized.
Described screens 203 is by the scope of activity of restriction rotating disk 4, thus limits the elasticity distortion scope of spring clip 209, prevents spring clip 209 stress deformation transition from causing elastic failure.
The principle of work of the safety interlock of described integral type line lock folding cutter is as follows: safety interlock lock two portions by safety interlock unblock and safety interlock and form.
The locking principle of described safety interlock: after operator 100 is opened, spring clip 209 elasticity is out of shape, and the side of spring clip 209 and the contacts side surfaces of operator 100, automatically lock operator 100, now promote rotating disk 4 forward, until the contacts side surfaces of convex post on rotating disk 4 44 and convex post slot to make way 207, and, the bottom surface of rotating disk 4 contacts with corner 204 FX, now, the side of operator 100 cannot be deviateed in the side of spring clip 209, and operator 100 cannot unlock, and forms safety interlock locking.
The unblock principle of described safety interlock: when safety interlock are in the lock state, promote rotating disk 4 backward, until the convex post 44 on rotating disk 4 contacts with the another side of convex post slot to make way 207, meanwhile, the arc notch 41 of rotating disk 4 avoids corner 204, now presses spring clip 209 outward, until rotating disk 4 bottom surface contacts with screens 203, operator 100 unblock, namely forms safety interlock and unlocks.
Above-mentioned explanation is the detailed explanation for the better possible embodiments of the utility model, but embodiment also is not used to limit patent application scope of the present utility model, the equal change or the modification that complete under technical spirit suggested by all the utility model are changed, and all should belong to the utility model and be contained patent scope.
