Interior to be equipped with pulling block, the pulling block is L-shaped, and the middle part of the pulling block is equipped with shaft, and the shaft is fixedly connected with pulling block, and described turn
It is flexibly connected between the right end of axis and right carriage saddle, the left side of the pulling block upper end is equipped with shaft, sets respectively on the shaft
There are first bearing and second bearing, the first bearing is set to the left side of second bearing, and the front side of the pulling block upper end is equipped with
Lug block, the lug block are equipped with small through hole, and the leading flank of right carriage saddle, the right knife rest are stretched out in the position of the lug block
The front side of seat upper end is equipped with blind rivet, and compressed spring, the front side of the deep gouge lower end are equipped between the blind rivet and small through hole
Equipped with positioning bolt, connection is engaged by screw thread between the positioning bolt and the lower end of deep gouge, after the positioning bolt
End peaks at the front side of pulling block lower end, the rear side of left knife rest seat lower end and right carriage saddle lower end it is rear between be equipped with knife
Frame fixed frame, the lower fixed blade are set to the front side of knife rest fixed frame, and the upper movable blades are set to the rear side of connecting shaft.
The left of the right carriage saddle is equipped with clearance fit seat, and the upper end of the clearance fit seat is set in connecting shaft,
And clearance fit seat is vertically fixed in connecting shaft by bolt, the lower end of the clearance fit seat is open equipped with matching seat,
The first bearing and second bearing are set in matching seat opening, and the left rear side in the matching seat opening is equipped with matching seat activity
The rear side of block, the matching seat movable block is equipped with several matching seat spring catch, and several matching seat spring catch are matched set on gap
It closes on seat, the front end of the matching seat spring catch peaks at the trailing flank of matching seat movable block, the front side of the matching seat movable block
Against the outer ring face with first bearing, the outer ring face of the second bearing is close proximity to the leading flank in matching seat opening, compression in face
Spring tenses lug block upwards, rotates counterclockwise pulling block by shaft, and rotating counterclockwise for pulling block makes pulling block lower end
Front side is withstood on positioning bolt, and matching seat movable block is pressed by matching seat spring catch to first bearing, and first bearing is by pressure
Pressure conduction to second bearing is made second bearing be close proximity to the leading flank in matching seat opening, gap by conduction to shaft, shaft
While matching seat is together with connecting shaft oscilaltion, realize that the leading flank in matching seat opening is mutual between second bearing always
It abuts, by adjusting the length for shortening positioning bolt rear end, pulling block is made to rotate counterclockwise the length that positioning bolt is shortened, pulling block
Rotate counterclockwise and move backward second bearing, because matching seat movable block abuts and first bearing always, matching seat is made to be open
Interior front side is also abutted with second bearing always, and the movement of second bearing backward rotates clockwise clearance fit seat, and gap is matched
That closes seat rotates clockwise and drives rotating clockwise for connecting shaft, realizes that rotating clockwise for connecting shaft makes movable blades
Lower end also rotates clockwise, and reaches when movable blades are contacted with lower fixed blade and is more bonded, conversely, by after positioning bolt
The length tune of end is long, rotates clockwise pulling block, and second bearing moves forward, and clearance fit seat rotates counterclockwise, connecting shaft
It rotates counterclockwise, upper movable blades rotate counterclockwise, and make between the lower end of movable blades and the leading flank of lower fixed blade
Gap when contact is bigger, by adjusting the length of positioning bolt rear end, controls upper movable blades and lower fixing cutter to realize
Compactness between piece, improves speed of production, reduces later period maintenance adjustment.
Between the left spring pin and left knife rest seat, between right spring catch and right carriage saddle and matching seat spring catch and gap
It is engaged and is connected by screw thread between matching seat, pass through rotatable elongate left spring pin, right spring catch and matching seat spring catch front end
Length, increase pressure suffered by left activity template, right activity template and matching seat movable block, conversely, shortening left bullet by rotation
The length of spring pin, right spring catch and matching seat spring catch front end makes suffered by left activity template, right activity template and matching seat movable block
Pressure increasing is small, and the increase of pressure reduces most important to compactness when contacting between upper movable blades and lower fixed blade.
The compressed spring is in retraction tensioning state, is in pulling block always under the tensioning state of spring, when upper activity
When being cut to hard object between blade and lower fixed blade, upper movable blades can be flicked counterclockwise, protect movable blades
With lower fixed blade.
Operation logic of the present invention: being lifted the both ends of connecting shaft by external force, while connecting shaft moves up, left activity
By the pressure of left spring pin, outer bearing side presses piece to the left, and right activity template is applied outer bearing side to the right by the pressure of right spring catch
Pressure, by pressure conduction to connecting shaft, connecting shaft conducts pressure to left inside bearing respectively for left outside bearing and right outer bearing at this time
On right inner bearing, pressure is by left inside bearing and right inner bearing respectively against in the leading flank of left open slot and right open slot, reality
Now it is on identical vertical line forever when upper movable blades bottom and top feed；Compressed spring tenses lug block upwards, makes pulling block
It is rotated counterclockwise by shaft, rotating counterclockwise for pulling block makes to withstand on positioning bolt on front side of pulling block lower end, and matching seat is living
Motion block by matching seat spring catch to first bearing press, first bearing by pressure conduction to shaft, shaft by pressure conduction extremely
Second bearing makes second bearing be close proximity to the leading flank in matching seat opening, and clearance fit seat is together with connecting shaft oscilaltion
Meanwhile realizing that the leading flank in matching seat opening mutually abuts between second bearing always, by adjusting positioning bolt is shortened
The length of rear end makes pulling block rotate counterclockwise the length that positioning bolt is shortened, the rotating counterclockwise of pulling block make second bearing to
After move, because matching seat movable block is close proximity to first bearing always, make matching seat be open in front side also always with second bearing
It abuts, the movement of second bearing backward rotates clockwise clearance fit seat, and clearance fit seat, which rotates clockwise, will drive connection
Axis rotates clockwise, and rotating clockwise for connecting shaft rotates clockwise the lower end of movable blades also, reaches movable blade
Piece is more bonded when contacting with lower fixed blade；Conversely, the length tune by positioning bolt rear end is long, revolve pulling block clockwise
Turn, second bearing moves forward, and clearance fit seat rotates counterclockwise, and connecting shaft rotates counterclockwise, and upper movable blades turn counterclockwise
It is dynamic, keep gap when contacting between the lower end of movable blades and the leading flank of lower fixed blade bigger, by adjusting positioning
The length of bolt rear end improves speed of production to realize the compactness controlled between upper movable blades and lower fixed blade,
Reduce later period maintenance adjustment.
Finally it is pointed out that above embodiments are only the more representational examples of the present invention.It is clear that the invention is not restricted to
Above-described embodiment, acceptable there are many deformations.Any letter to the above embodiments according to the technical essence of the invention
Single modification, equivalent variations and modification, are considered as belonging to the scope of protection of the present invention.
