Description

Strength cutting tool

Technical field

The present invention relates to hardware and cutting-tools technical field, a kind of paper knife or U.S. that there is strength to cut effect is especially belonged to Work knife.

Background technology

Paper knife or cutter be the more commonly used cutting tool, is generally used for paper, cloth, plastic or other material and cuts Cut.Development and the demand that uses with technology, guideway paper cutters structure at present on the market are of all kinds, and structure is excessively multiple Miscellaneous, difficult processing is difficult assembling, and production cost is high, and when using blade tremble, it is easily broken, cut limited in one's ability, operability is not yet Ideal, Shortcomings are gone back in terms of the convenience, security used to the greatest extent.

The content of the invention

The purpose of the present invention is to be to provide a kind of strength cutting tool, to reach practical and convenient and ensure using safety Purpose.

Strength cutting tool provided by the present invention, it is characterised in that with body, body include knife lid, tool rest with And the handle around tool rest is wrapped in, handle forms the Baltimore groove corresponding with the side of knife lid two respectively in the both sides of tool rest, Knife lid is coupled with tool rest by the bearing pin of front end, wherein, cutter hub is provided with knife lid, cutter hub includes being parallelly mounted to knife lid Blade in concave shaped chute and the push-and-pull plectrum being connected on blade, the gap that blade is formed from knife lid and tool rest front end Middle to stretch out, the handle rear end position corresponding with knife lid rear end is provided with locking mechanism.

The locking mechanism includes being arranged at the telescopic dead bolt of handle tail end and is arranged at knife lid rear end stop block On, the spill lockhole corresponding with dead bolt.

Blade rear end is provided with blade connecting hole, and push-and-pull plectrum front end is provided with the blade being engaged with blade connecting hole and is connected Body and push-and-pull projection.

There is a groove, bottom portion of groove is on comb teeth-shaped bottom plate, the comb teeth-shaped bottom plate and push-and-pull plectrum inside tool rest Push-and-pull projection is engaged.

Further, the tool rest and handle are formed in one structure.

Further, the tool rest front end is provided with spring groove, and spring leaf is installed in spring groove.

Further, fixed magnet is provided between the blade connector and push-and-pull projection on the push-and-pull plectrum.

Further, the handle both sides are provided with anti-slip veins.

Further, the tool rest front end constitutes a segmental arc relative to the pin-and-hole opened up on tool rest, and segmental arc is used as using pin-and-hole Central point, the length in the longitudinal edge footpath of segmental arc is less than the widthwise edge electrical path length of segmental arc.

Strength cutting tool provided by the present invention, it is simple and compact for structure, push-and-pull can be passed through according to the demand of user Projection, realizes the release of blade or retracts, the fixed magnet set between blade connector and push-and-pull projection, on the one hand to push away Draw plectrum and being coupled for blade more firm, on the other hand also further enhance fixed effect of the blade in knife lid, together When, the setting of knife lid substantially increases security performance when blade is used.The comb teeth-shaped bottom plate that bottom portion of groove is set so that Blade realizes the fixation of blade during push-and-pull, preferably, is difficult to rock, and advantageously ensures that using effect, anti-slip veins Design, also improve hommization demand, in summary, the present invention it is easy to operate, with improve practicality and ensure use The good effect of safety.

Brief description of the drawings

Accompanying drawing part discloses the specific embodiment of the invention, wherein,

Fig. 1 is the structural representation under state 1 of the present invention；

Fig. 2 is the structural representation under state 2 of the present invention；

Fig. 3 is the structural representation of push-and-pull plectrum of the present invention；

Fig. 4 is the structural representation of body front end of the present invention.

Embodiment

As Figure 1-3, strength cutting tool provided by the present invention, with body, body includes knife lid 1, top The tool rest 2 corresponding with knife lid of opening and the handle 3 being wrapped in around tool rest.Wherein, handle divides in the both sides of tool rest Baltimore groove 4 that Xing Cheng be not corresponding with the side of knife lid two, knife lid is coupled with tool rest by the bearing pin 5 of front end.

Cutter hub is provided with knife lid, cutter hub includes the blade 6 being parallelly mounted in knife lid concave shaped chute and connection Stretched out in the gap that the push-and-pull plectrum 7 on blade, blade are formed from knife lid and tool rest front end, so that user is used. Blade rear end is provided with blade connecting hole, push-and-pull plectrum front end be provided with the blade connector 8 that is engaged with blade connecting hole and Push-and-pull projection 9；There is a groove, bottom portion of groove is comb teeth-shaped bottom plate 10, the comb teeth-shaped bottom plate and push-and-pull plectrum inside tool rest On push-and-pull projection be engaged, in addition, the handle rear end position corresponding with knife lid rear end be provided with locking mechanism, it is described sealed Mechanism includes being arranged at the telescopic dead bolt 11 of handle tail end and being arranged on knife lid rear end stop block 12, with dead bolt phase Corresponding spill lockhole 13.

Preferably, the tool rest front end is provided with spring groove, and spring leaf is installed in spring groove, and automatic by spring leaf returns Bullet, so as to be conducive to the unlatching of knife lid.

Preferably, fixed magnet 14 is provided between the blade connector and push-and-pull projection on the push-and-pull plectrum, on the one hand So that push-and-pull plectrum and being coupled for blade are more firm, fixed effect of the blade in knife lid is on the other hand also further enhanced Really, meanwhile, the tool rest and handle are formed in one structure, also further enhance integrally-built stability of the invention.

In order to improve the human oriented design of the present invention, the handle both sides are provided with anti-slip veins 15.

In addition, in order to solve the drawbacks of blade or so loosens and trembleed up and down, as shown in figure 4, tool rest front end phase For the pin-and-hole 16 opened up on tool rest, a segmental arc, using pin-and-hole as the central point of segmental arc, the longitudinal edge footpath Y of segmental arc length are formed Widthwise edge footpath X length of the degree less than segmental arc.So, the activity space of 90 degree of angle is formd between knife lid and tool rest, The angle that the size of activity space is opened with knife lid is different and changes.Particularly, when knife lid closes up to horizontal direction With tool rest into 0 degree of angle state when and be flared to vertical direction completely with tool rest into the state of 90 degree of angles, activity The thickness in space is exactly equal to or is slightly less than the thickness of blade, and blade is clamped, is relatively fixed with tool rest, knife lid, forms one Individual entirety；Conversely, when knife lid is under half open configuration, i.e., activity space is in knife lid and the 0-90 degree of tool rest formation is pressed from both sides In the interval at angle during activity, the thickness of activity space is more than the thickness of blade, and blade can freely be stretched according to the demand of user The certain length of contracting.In this way it is ensured that the fastening during blade use, it is ensured that the accuracy of blade straight cuts, from And the security used is enhanced, substantially increase service efficiency.
