Abstract

The invention relates to an art designing knife regulator. The art designing knife regulator comprises an iron knife handle arranged on an art designing knife shell. A plurality of open locking grooves are arranged on one side of the iron knife handle, a lower regulating block is arranged above the iron knife handle movably, a protruded portion matched with a blade fixing hole is arranged on the front end of the lower regulating block, and a locking block and an elastic piece are arranged in the lower regulating block movably. Two locking feet are arranged on the upper end of the locking block and matched with the locking grooves. The tail ends of two arms of the elastic piece abut against the inner wall of the lower regulating block, and the top of the elastic piece abut against the bottom of the locking block. A movable upper regulating block is arranged above the lower regulating block, two pushing grooves are arranged on one side of the upper regulating block and respectively correspond to the two locking feet in position, and the inner walls of the groove openings abut against the outer walls of the locking feet. The art designing knife regulator is large in locking force, stable in structure, few in needed part, capable of reducing manufacture cost, free of limitation of art designing knife sizes, wide in application range and attractive in appearance.

Description

The cutter adjuster

Technical field

The present invention relates to the cutter field, refer to especially a kind of cutter adjuster.

Background technology

More common cutter controller structure as shown in Figure 2 in the market, mainly comprise adjusted piece 1, lower regulating block 2 and back-moving spring, be provided with clamping block 5 and the clamping block spring 6 that matches with lock slots 4 on the iron handle of a knife 3 at lower regulating block 2, it is inconsistent with clamping block 5 respectively to be provided with 7, two inclined-planes 7, two inclined-planes in adjusted piece 1 and clamping block 5 corresponding positions.

During locking, when adjusted piece 1 and lower regulating block 2 were failure to actuate, clamping block 5 was stuck in the lock slots 4 under the elastic force of clamping block spring 6, realized locking.

When feed or withdrawing, finger presses adjusted piece 1 advances adjusted piece 1 or retreats, and the inclined-plane 7 on the adjusted piece 1 promotes clamping blocks 5, make clamping block 5 overcome spring force, regulating block 2 directions move downwards, thereby break away from iron handle of a knife 3, so that lower regulating block 2 moves forward or retreats, when entering into next lock slots 4, clamping block 5 sticks in the next lock slots 4 under the elastic force effect of clamping block spring 6, and lower regulating block 2 also resets under the effect of back-moving spring.

This adjuster is in the situation of large cutting force, and latching force is subjected to the impact of the lock slots degree of depth, if lock slots is dark not, then is easier to occur clamping block and breaks away from, and then blade is skidded off without early warning, easily cause danger; And promoting clamping block with spring is locked in the lock slots, because the maximum compressibility of spring is 30 percent of drift, so it is darker that tooth is done, the clamping block stroke is longer, and spring will be longer, and the width of lower regulating block usually is subject to the restriction of structure and size, cause this adjuster can not be applicable to the cutter of all size, in addition, this controller structure is complicated, number of spare parts is more, and manufacturing cost is higher.

Summary of the invention

Technical problem to be solved by this invention is: preferably cutter adjuster of wider, the simple in structure and locking effect of a kind of scope of application is provided.

For addressing the above problem, the technical solution used in the present invention is: the cutter adjuster, comprise the iron handle of a knife that is arranged on the cutter shell, iron handle of a knife one side is provided with the lock slots of several openings, iron handle of a knife top is movably set with lower regulating block, lower regulating block front end is provided with the protuberance that matches with the blade fixing hole, be movably set with clamping block and shell fragment in the lower regulating block, the clamping block upper end is provided with two locking pin, the locking pin matches with lock slots, shell fragment two arms are terminal inconsistent with lower regulating block inwall, shell fragment top and clamping block bottom are inconsistent, and lower regulating block top is provided with movable adjusted piece, and adjusted piece one side is provided with two and promotes groove, two promotion grooves are corresponding with the positions of two locking pin respectively, and the notch inwall is inconsistent with locking pin outer wall.

Described promotion groove notch is towards the locking pin, and wide outside and narrow inside, notch both sides inwall is two inclined-planes.

Described clamping block bottom is provided with groove, and the shell fragment top is provided with circular-arc projection, and groove matches with projection.

The invention has the beneficial effects as follows: above-mentioned cutter adjuster, latching force is large and structure is more stable, and required part is few, has reduced the cost of making, and is not subjected to the restriction of cutter size, and the scope of application is wider, and profile is also more attractive in appearance.

The specific embodiment

Below by specific embodiment cutter adjuster of the present invention is described in further detail.

As shown in Figure 1, the cutter adjuster, comprise the iron handle of a knife 1 that is arranged on the cutter shell, iron handle of a knife 1 one sides are provided with the lock slots 2 of several openings, iron handle of a knife 1 top is movably set with lower regulating block 3, lower regulating block 3 front ends are provided with the protuberance 4 that matches with the blade fixing hole, be movably set with clamping block 5 and shell fragment 6 in the lower regulating block 3, clamping block 5 upper ends are provided with two locking pin 7, locking pin 7 matches with lock slots 2,6 liang of arms of shell fragment are terminal inconsistent with lower regulating block 3 inwalls, shell fragment 6 tops and clamping block 5 bottoms are inconsistent, and lower regulating block 3 tops are provided with movable adjusted piece 8, and adjusted piece 8 one sides are provided with two and promote groove 9, two promotion grooves 9 are corresponding with the positions of two locking pin 7 respectively, and the notch inwall is inconsistent with locking pin 7 outer walls.

Described promotion groove 9 notches are towards locking pin 7, and wide outside and narrow inside, notch both sides inwall is two inclined-planes.

Described clamping block 5 bottoms are provided with groove 10, and shell fragment 6 tops are provided with circular-arc protruding 11, and groove 10 matches with projection 11.

During locking, adjusted piece 8 and lower regulating block 3 all are failure to actuate, and locking pin 7 is stuck in the lock slots 2 under shell fragment 6 motive forces, realizes locking; When feed or withdrawing, finger presses adjusted piece 8, adjusted piece 8 is advanced or retreat, promotion groove 9 on the adjusted piece 8 promotes locking pin 7, and it is mobile that locking pin 7 is overcome in the downward regulating block 3 of shell fragment 6 elastic force, thereby go out of lock groove 2, lower regulating block 3 is advanced or retreat, when entering into next lock slots 2, locking pin 7 snaps in the lock slots 2 under the effect of shell fragment 6 power.

The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
