Medial surface be provided with rotating disk slot to make way 202, spring groove 206 and projection slot to make way 207, and central point is linearly distributed.
The projection slot to make way 207 of the first handle 200 is communicated with spring groove 206, projection slot to make way 207 and step rotating shaft
Hole 208 connects.
The screens 203, corner 204 are located at the medial surface of first handle 200, and the depth of screens 203 is stepped down more than rotating disk
The depth of groove 202
The rotating disk slot to make way 202, screens 203, corner 204, spring groove 206 and projection slot to make way 207 are located at first-hand
The medial surface of handle 200；Wherein, rotating disk slot to make way 202, spring groove 206 and projection slot to make way 207 be located in spring clip 209 and
Central point is linearly distributed；Depth of the depth of screens 203 more than rotating disk slot to make way 207.
As shown in fig. 6, second handle 300 includes second handle front end 301, second handle rear end 302, the second through hole
303rd, the second spacer sleeve hole 304, the second stop bit nail 305 and the second interval screw hole 306.
As shown in fig. 7, the rotating disk 4 includes arc notch 41, screw hole 42, rotating shaft counterbore 43, projection 44.
As shown in figure 8, the spring 5 includes lateral surface 51.
As shown in figure 9, the 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, rotating disk 4 is arranged on rotating disk slot to make way 202
Interior, projection 44 on rotating disk 4 is located inside projection slot to make way 207, and with the Elastic Contact of lateral surface 51 of spring 5.
The projection slot to make way 207 of the first handle 200 is connected with step shaft hole 208, and projection 44 can be from during installation
Step shaft hole 208 is moved on to and allows projection slot to make way 207, the elasticity of the limited spring locking plate 209 of screens 203 on first handle 200
Deformation range, can prevent the deformable transition of spring clip 209 from causing elastic failure.
The big step 33 of the step rotating shaft 3 is arranged in the step shaft hole 42 of rotating disk 4, the step end face of big step 33
In the rotating shaft counterbore 43 of rotating disk 4, small stair 32 is arranged in the step shaft hole 208 of first handle 200, small stair 32
Step end face is contacted 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 separately mounted in the first stop bit nail 212 and the second stop bit nail 305.
Riveting screw 8 is riveted tightly fixation through first handle 200 and with the screw through-hole 31 of step rotating shaft 3.Will be described
Main shaft 9 is each passed through the second through hole 303, operator through hole 101 and first through hole 201, and tightens fixation by main shaft screw 7.By institute
The two ends of the spacer sleeve 12 stated are separately mounted to the first spacer sleeve hole 213 and the second spacer sleeve hole 304, and are twisted by interval screw 10
Fasten.
Further, the both sides of the projection slot to make way 207 limit the moving range of projection 44, so as to limit rotating disk 4
Slewing area.When the projection 44 on rotating disk 4 moves to the centre position of projection slot to make way 207, the spring resistance that projection 44 is subject to
Power is maximum；When projection 44 touches the both sides of projection slot to make way 207, the spring resistance that projection 44 is subject to is minimum, and rotating disk 4 is steady
It is fixed.
Described screens 203 by limiting the scope of activities of rotating disk 4 so that the elastic deformation model of limited spring locking plate 209
Enclose, prevent the stress deformation transition of spring clip 209 from causing elastic failure.
The operation principle of the safeties of the integral type line lock folding cutter is as follows：Safeties are unlocked by safeties
Two parts are locked with safeties to constitute.
The locking principle of the safeties：After operator 100 is opened, the elastic deformation of spring clip 209, spring clip
209 side and the contacts side surfaces of operator 100, lock operator 100 automatically, rotating disk 4 are now promoted forward, until on rotating disk 4
The contacts side surfaces of projection 44 and projection slot to make way 207, also, the bottom surface of rotating disk 4 contacts with the FX of corner 204, now, bullet
The side of spring locking plate 209 cannot deviate the side of operator 100, and operator 100 cannot be unlocked, and form safeties locking.
The unblock principle of the safeties：When safeties are in the lock state, rotating disk 4 is promoted backward, until turning
Projection 44 on disk 4 is contacted with the another side of projection slot to make way 207, and at the same time, the arc notch 41 of rotating disk 4 avoids side
Angle 204, now presses spring clip 209 outward, until the bottom surface of rotating disk 4 contacts with screens 203, operator 100 is unlocked, that is, formed and protected
Dangerous device unblock.
Described above is directed to the detailed description of preferably possible embodiments of the invention, but embodiment is not limited to this hair
Bright patent claim, the equal change completed under the technical spirit suggested by all present invention or modification change, all should belong to
Cover the scope of the claims in the present invention.
