Abstract

The invention relates to a double-spring-plate and double-locking structure for an art knife adjuster. The structure comprises a lower adjusting block matched with an art knife blade frame with tooth slots in both of the two sides; two symmetrically-arranged spring plates are fixed on the lower adjusting block; each spring plate is provided with two clamping parts; the two clamping parts of each spring plate are positioned on the two sides of the lower adjusting block, respectively, and are clamped with the tooth slots in the two sides of the art knife blade frame in a matched manner, respectively. The double-spring-plate and double-locking structure for the art knife adjuster, provided by the invention, has the advantages as follows: as the two spring plates and the four clamping parts are arranged, the locking force is large and the adjuster is uneasy to retract during use; gaps between the clamping parts and the tooth slots of the blade frame are offset through the four clamping parts, so that the adjuster has low probability of shaking within the blade frame after being locked; moreover, as the structure is used together with an upper adjusting block of the adjuster in the adjusting process, locking of one spring plate is overcome, so that the pushing force during adjusting is still small.

Description

Two shell fragment tow-locking structures of adjuster of art knife

Technical field

The present invention relates to a kind of cutter, particularly relate to a kind of two shell fragment tow-locking structures of adjuster of art knife.

Background technology

At present, although cutter thrust in adjustment process of shell fragment lock adjustment device is lighter, but in use latching force is little, staff slightly is just easy to be contracted with draught control mechanism when using cutting, now blade is just easy to fracture, thus may damage staff, and there is the problems such as distortion due to shell fragment, after locking, free gap is comparatively large, and adjuster easily rocks in blade holder.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of latching force comparatively large, and adjuster is not easy two shell fragment tow-locking structures of the adjuster of art knife of rocking in blade holder.

For solving the problem, the technical solution used in the present invention is: two shell fragment tow-locking structures of adjuster of art knife, comprise the lower regulating block all having the razor blade for carving tool frame of teeth groove to match with both sides, described lower regulating block is fixed with two symmetrically arranged shell fragments, each shell fragment all has two clamping parts, and two clamping parts of each shell fragment lay respectively at the both sides of lower regulating block and the card that matches with the teeth groove of razor blade for carving tool frame both sides is respectively established.

Preferably, described two elastic piece structures are identical.

Preferably, two clamping part structures of described each shell fragment are identical.

Preferably, the clamping part of described shell fragment is hook-shaped.

Preferably, the hook-shaped clamping part of described shell fragment is established by the hook-shaped bending part card that to match with the teeth groove of razor blade for carving tool frame both sides.

The invention has the beneficial effects as follows: the present invention is owing to being provided with two shell fragments, four clamping parts altogether, when using cutting, latching force is large, adjuster is not easy to be contracted, four clamping parts make up the gap of establishing existence with blade holder teeth groove card each other, thus are not easy after making controller lock to rock in blade holder; And in adjustment process by with regulating block on adjuster with the use of the locking overcoming one of them shell fragment, thus thrust when making adjustment is still lighter.

Detailed description of the invention

Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described.

As shown in Figure 1 and Figure 2, two shell fragment tow-locking structures of described adjuster of art knife, comprise the lower regulating block 1 all having the razor blade for carving tool frame 3 of teeth groove to match with both sides, one end of lower regulating block 1 is provided with a projection 11 matched with blade fixing hole, described lower regulating block 1 is fixed with two symmetrically arranged shell fragments 2, each shell fragment 2 all has two clamping parts, and two clamping parts of each shell fragment 2 lay respectively at the both sides of lower regulating block 1 and the card that matches with the teeth groove of razor blade for carving tool frame 3 both sides is respectively established; The structure of the present invention to the structure of shell fragment 2 and shell fragment 2 clamping part is not particularly limited, when preferentially selecting, two shell fragment 2 structures of the present invention are identical, two clamping part structures of each shell fragment 2 are also identical, the clamping part of described shell fragment 2 and be hook-shaped, be convenient to like this produce, and production technology is simple; As shown in Figure 3, the hook-shaped clamping part of shell fragment 2 of the present invention is established by hook-shaped bending part 21 card that to match with the teeth groove of razor blade for carving tool frame 3 both sides, and this mode card is established effective, and does not affect the adjustment of adjuster.

As shown in Figure 3, in use, when adjuster drives blade adjustment to desired location, four hook-shaped clamping parts of two shell fragments 2 just can block with the teeth groove of blade holder 3 both sides mutually to be established, and is just now lock-out state, owing to now being established by the card of four hook-shaped clamping parts, its latching force is relatively large, and staff, when using cutting, exerts oneself so long as not undue, its latching force can meet need of work completely, thus not easily the situation of adjuster retraction occurs; Again because four hook-shaped clamping parts compensate for the gap of establishing existence with blade holder 3 teeth groove card each other, be not easy to rock after making controller lock in blade holder 3, therefore can not bring the discomfort in feel when using cutting to staff, being convenient to cutting.

The present invention is owing to being provided with two shell fragments 2, four clamping parts altogether, when using cutting, latching force is large, and adjuster is not easy to be contracted, four clamping parts make up the gap of establishing existence with blade holder 3 teeth groove card each other, thus are not easy to rock after making controller lock in blade holder 3; And in adjustment process by with regulating block on adjuster with the use of the locking overcoming one of them shell fragment 2, thus thrust when making adjustment is still lighter.
