Description

A kind of cutter adjuster

Technical field

The utility model relates to the cutter field, refers to especially a kind of cutter adjuster.

Background technology

More common cutter adjuster in the market, mainly comprise adjusted piece, lower regulating block and back-moving spring, be provided with clamping block and the clamping block spring that matches with lock slots on the handle of a knife at lower regulating block, be provided with two inclined-planes in the adjusted piece position corresponding with clamping block, two inclined-planes are inconsistent with clamping block respectively.

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

When feed or withdrawing, finger presses adjusted piece advances the adjusted piece or retreats the slope driving clamping block on the adjusted piece, make clamping block overcome spring force, the regulating block direction moves downwards, thereby breaks away from handle of a knife, so that lower regulating block moves forward or retreats, when entering into next lock slots, clamping block sticks in the next lock slots under the elastic force effect of clamping block spring, and lower regulating block also resets under the effect of back-moving spring.

This adjuster is in the situation that 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.

The utility model content

Technical problem to be solved in the utility model is: preferably a kind of 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 adopted in the utility model is: a kind of cutter adjuster, comprise the handle of a knife that is arranged on the cutter shell, be provided with several lock slots in the handle of a knife, the 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 provided with the clamping block groove in the lower regulating block, be movably set with the clamping block of T font in the clamping block groove, match with lock slots in the lower end of clamping block, lower regulating block top is provided with movable adjusted piece, adjusted piece both sides are respectively arranged with one and promote groove, promote the groove notch wide outside and narrow inside, the plane of notch bottom for matching with clamping block, notch both sides inwall is the inclined-plane, be provided with shell fragment between adjusted piece and the lower regulating block, shell fragment two arms are terminal inconsistent with adjusted piece inwall, and shell fragment bottom and clamping block top phase lock fit also are provided with resetting means in the adjusted piece.

Described lock slots is blind bore type structure, and lock slots matches with clamping block.

Described shell fragment bottom is provided with square groove, and the groove inwall matches with clamping block upper end outer wall.

Described resetting means comprises two jig arm and the reset bar that is arranged on the adjusted piece, and reset bar is made by elastomeric material, and the reset bar two ends are fixed on the inwall of lower regulating block both sides, and two jig arm are separately positioned on the reset bar both sides, and inconsistent with reset bar.

The beneficial effects of the utility model are: above-mentioned a kind of cutter adjuster, and 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 a kind of cutter adjuster of the utility model is described in further detail.

Such as Fig. 1, Fig. 2 and a kind of cutter adjuster shown in Figure 3, comprise the handle of a knife 1 that is arranged on the cutter shell, handle of a knife 1 bottom is provided with several lock slots 2 in the present embodiment, lock slots 2 also can be arranged on the side of handle of a knife 2, 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 provided with clamping block groove 5 in the lower regulating block 3, be movably set with the clamping block 6 of T font in the clamping block groove 5, match with lock slots 2 in the lower end of clamping block 6, lower regulating block 3 tops are provided with movable adjusted piece 7, adjusted piece 7 both sides are respectively arranged with one and promote groove 8, promote groove 8 notches wide outside and narrow inside, the plane of notch bottom for matching with clamping block 6, notch both sides inwall is the inclined-plane, be provided with shell fragment 9 between adjusted piece 7 and the lower regulating block 3, shell fragment 9 liang of arm arts end and adjusted piece 7 inwalls are inconsistent, and shell fragment 9 bottoms and clamping block 6 top phase lock fit also are provided with resetting means 10 in the adjusted piece 7.

Described lock slots 2 is blind bore type structure, and lock slots 2 matches with clamping block 6.
