9. a kind of cut-out method of sand paper clipper easy to use according to claim 8, which is characterized in that transmission is certainly
Latch mechanism includes first connecting rod (4) and second connecting rod (5), and one end of first connecting rod (4) is fixedly connected on one end of shaft (2),
The other end of first connecting rod (4) is rotationally connected with one end of the second connection (5), and the other end of the second connection (5) is rotationally connected with
In upper fixture block (6), first connecting rod (4) is equipped with the linkage section that section is L-type, and the linkage section of L-type includes perpendicular section (41) and crosspiece
(42), second connecting rod (5) is hinged in the perpendicular section (41) of L-type linkage section；
The lower end of second connecting rod (5) is generally arc-shaped, and its lower end surface is plane (51), and the center of the arc surface is described in
The distance of plane (51) is less than the radius of the arc surface, and the arc surface is with the rotation between first connecting rod (4) and second connecting rod (5)
The axial line of axis is center line, when first connecting rod (4) and second connecting rod (5) draw a straight line, the plane (51) and cross
Section (42) end face is close to, it can be achieved that crosspiece (42) is to the position-limiting actions of second connecting rod (5), in first connecting rod (4) and second connecting rod
(5) by applying lesser power between, the frictional force of arc surface Yu crosspiece (42) end face can be overcome, make first connecting rod (4) and
Second connecting rod (5) relative motion.
In step A:
Shaft (2) rotation, the free end of first connecting rod (4) are swung up, and are jacked up upper fixture block (6) by second connecting rod (5), the
During one connecting rod (4) sustained oscillation, when first connecting rod (4) and second connecting rod (5) are in same straight line, first connecting rod
(4) crosspiece (42) of L-type linkage section can abut against second connecting rod (5) on, and first connecting rod (4) is not continuing to swing, while the
The junction of one connecting rod (4) and second connecting rod (5) is located at dead-centre position, and after unclamping hand handle (1), upper fixture block (6) is in first connecting rod
(4) it is not fallen out under the supporting role of second connecting rod (5), the sand paper that can treat cutting at this time is put；
It presses downwards hand handle (1), shaft (2) rotation, makes the effect for generating power between first connecting rod (4) and second connecting rod (5), gram
The frictional force for taking arc surface Yu crosspiece (42) end face, makes first connecting rod (4) and second connecting rod (5) relative motion, upper fixture block (6) to
Lower rotation, the pressing ring (17) in upper fixture block (6) push down sand paper to be cut.
10. a kind of cut-out method of sand paper clipper easy to use according to claim 8, which is characterized in that upper
It is respectively and fixedly provided with connecting column (8) on fixture block (6) and the side wall of lower fixture block (3), passes through back-moving spring (9) between two connecting columns (8)
Connection,
In step A:
It pushes handle (1), back-moving spring (9) pulls down upper fixture block (6), and the pressing ring (17) in upper fixture block (6) will sand paper be cut
It pushes down.
