Abstract
The utility model relates to a special manual cutting knife carrier, which belongs to the technical field of manual cutting tools and comprises a knife carrier body and a lateral cover plate mounted on the lateral surface of the knife carrier body in a covering manner. A slot allowing insertion of a blade is formed between the lateral cover plate and the lateral surface of the knife carrier body, a lever is hinged on the lateral surface of the knife carrier body provided with a sliding groove extending to the top surface of the knife carrier body, a spring and a button are arranged inside the sliding grove, the button extends out of the top surface of the knife carrier body, one end of the lever extending into the sliding groove is clamped between the top surface of the spring and the bottom surface of the button, the other end of the lever extends into the slot, and a projecting block matching with a notch on the back of the blade is manufactured at the other end of the lever. A lever mechanism of the knife carrier used as a locking mechanism of the blade is simple and reliable in structure, and accordingly the knife carrier can conveniently and reliably complete assembly and disassembly of the blade.
Description
Technical field
The utility model relates to the special-purpose member-tool rest on a kind of manual cutting knife, belongs to the hand cutting tool technical field.
Background technology
Manually cutting knife is the hand cutting tool commonly used that is used to cut article such as paper, leather, cloth and plastics, and its structure generally is to be made of tool rest that is coupled to each other and handle of a knife and blade three parts that are plugged on the tool rest.Wherein, blade and tool rest generally are to fix and separate by lockable mechanism, so that blade is with changing long afterwards.Known to existing blade and the lockable mechanism of tool rest have several, but or complex structure, easy break-down, operation inconvenience, or too coarse and be difficult to reliable use.Such as, the disclosed a kind of cutting knife tool rest of the Chinese patent of application number 200720051673.5, constitute the lockable mechanism of blade on this tool rest by runner, lock pin, shifting block and spring, complex structure not only, and the not good and inconvenient use of perception during because of hand behaviour runner.Again such as, the disclosed hand knife of being convenient to change blade of the Chinese patent of application number 200910308327.4, the lock piece structure that this hand knife is provided with on its tool rest is trifling perishable, and remains with hand and rotate lock piece, though rotation amplitude is big, still feel is not good, operation is hard.For another example, the paper knife of the disclosed a kind of changeable blade of Chinese patent of application number 200920193791.9, though the lockable mechanism that this paper knife is provided with on its tool rest is simple in structure, but latch fitting only supports by spring, when pushing latch fitting, spring can deform and move, and can't make protruding the recess of tipping in or leaving on the blade of latch fitting end at all, that is to say that this paper knife is difficult to normally carry out blade exchange.
The utility model content
The technical problems to be solved in the utility model is to propose a kind of tool rest of being convenient to change blade on the manual cutting knife that is exclusively used in.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: the special-purpose tool rest of a kind of manual cutting knife, comprise tool rest body and the side cover plate that is installed on tool rest body one side, form the slot that can insert blade between described side cover plate and tool rest body one side, described tool rest body one side is hinged with lever and is provided with the chute that passes to tool rest body end face, is provided with spring and the button that stretches out tool rest body end face in the described chute; One end of described lever stretches in the chute and is sandwiched between spring end face and the button bottom surface, and its other end stretches in the slot and is shaped on the projection that matches with blade back breach.
When tool rest of the present utility model used: press the button, button overcomes spring force to be depressed an end of lever simultaneously, and the other end of lever just lifts, and can insert new blade in the slot or with old blade and draw off in slot this moment; The end that release button then, spring reset promote lever lifts and the other end falls, and the projection of the lever other end just is stuck in the breach of blade back, thereby pins blade.
Tool rest of the present utility model passes through the lockable mechanism of the simple and reliable leverage of project organization as blade, the loading and unloading of finishing blade reliably can both conveniently be arranged, compare existing mode of loading and unloading blade by a plurality of finger rotation lock locking mechanisms, tool rest of the present utility model needs only single light finger by finishing the blade loading and unloading, and is therefore convenient, efficient and reliable.
The one of perfect of technique scheme is: described tool rest body one side also is provided with second chute that passes to tool rest body end face, be provided with second spring in described second chute and stretch out second button of tool rest body end face, a side of described second button is shaped on the slide block that can match with the chute of the handle of a knife inboard of manual cutting knife.
Perfect two of technique scheme is: described tool rest body one side also be provided with can be hinged with the handle of a knife of manual cutting knife pin-and-hole.
