Abstract

The utility model relates to a gravity knife tool for art designing, comprising an upper and a lower tool aprons which can be wedged and pivoted right and left with two phases via cutting and a tool apron clamping body pivoted at the intermediate section of the lower tool apron. The front section of the inner side of the lower tool apron is provided with a slide way for bearing blades, the intermediate section of the lower tool apron is provided with a spacing slot for accommodating a control knife body and a storage slot for placing spare blades, and the side part of the intermediate section is provided with a through hole for pivoting the tool apron clamping body. The inner side structure of the upper tool apron is matched with the corresponding inner side structure of the lower tool apron, and the outer side of the upper tool apron is provided with a guide rail for causing the tool apron clamping body to slide on and a clamping flange. The knife tool can be used assembled and disassembled quickly, the blades can be changed simply, and the extended length of the blades can be directly adjusted.

Description

Gravity knife tool for art designing

The utility model relates to a kind of hand tools.

It is of a great variety for the existing art designing's cutter that is used to cut, and only is divided into for light power art designing's cutter of literature articles for use and is the gravity art knife tool of cutting millboard, plastics, rubber according to purposes is unusual.Usually, the structure of light power art designing cutter is light and handy, and good looking appearance is only used for the cutting of general paper, work works; And the gravity art knife tool is firm in structure, and the locking of blade is had relatively high expectations, and abundant clumsiness therefore seems.

Existing a kind of gravity art knife tool mainly comprises and cuts open the tool rest up and down that is set as the two-phase wedging, wear two corresponding mutually screws up and down on the side up and down of tool rest, to borrow two screws that one blade lock knot is fixed in the slotted eye of tool rest front end, the half dog hole cover hook that cooperates blade one side again is in the prominent body of the stop of following tool rest, rock before and after cutting produces during article so that prevent blade, and at the inner blade of putting some pre-storages of tool rest up and down.Though this cutter is firm in structure, the locking of blade is reliable, when changing blade, needs earlier the screw spin-up, and needs after changing once more with screw means, changes not only time-consuming but also trouble of formality, and screw is also lost easily; Secondly, when cutter time spent not, blade if in the tool rest of desiring to withdraw fully to avoid accidental cuts, also need as the replacing blade bother; Simultaneously, when desire is cut thicker working substance,, influence its practicality because of its length that protrudes out that can't directly adjust blade.

The purpose of this utility model provides a kind of firm in structure, and the loading and unloading blade is easy, quick, can directly adjust the gravity art knife tool that blade protrudes out length.

The design comprises and cuts open the tool rest up and down that is set as the two-phase wedging, respectively establishes a relative up and down open-work at the end of tool rest up and down, and wears its chien shih pivot knot wedging with a hitching post, make up and down tool rest according to this hitching post be the center of circle and left and right sides pivot is moving separates or wedging.Other establishes a pivot at the following tool rest clamp of tool rest stage casing side, and its leading portion of clamping does not make and can separate voluntarily easily when tool rest wedging up and down.

The inboard leading portion of following tool rest is provided with chute, establishes the blade bearing on the chute, and the stage casing is provided with and holds the storage groove that the spacing tank and of control cutter hub provides the spare blade storing, and the perforation that provides the tool rest clamp to be pivoted is provided the stage casing side.The structure of upper cutter head inboard then cooperate the structure of relative following tool rest inboard, and its outside is provided with one and provides the guide rail of tool rest clamp slippage and a card to end flange.The front of the blade bearing under being located in the tool rest leading portion chute is provided with the stop convex body in order to hook knot fixed blade, end side then is connected fixed with a control cutter hub, this control cutter hub is camber arch and has elasticity, and its hogback peak is provided with a protruding outer push button of cutter that is exposed to.

Compare with existing gravity art knife tool, the pivot roped party of tool rest and tool rest clamp was closed about the utility model was borrowed, and can promptly cutter be disassembled or make up, and it is easy to change blade; Borrow the blade bearing in addition and control cooperating of cutter hub, can directly adjust the length that protrudes out of blade, be convenient to the user and operate utilization.

Fig. 1 is the three-dimensional exploded view of gravity art knife tool.

Fig. 2 is the three-dimensional combination figure of gravity art knife tool.

Fig. 3 and Fig. 4 are the action step figure of gravity art knife tool.

Embodiment: as depicted in figs. 1 and 2, the utility model comprises and cuts open the tool rest up and down (1 that is set as two phase wedgings, 2), respectively establish a relative up and down open-work (11,21) at the end of tool rest up and down, and wear therebetween and pivot knot wedging with a hitching post (3), making up and down tool rest rely on this hitching post is the center of circle and left and right sides pivot is moving separates or wedging, simultaneously, borrows a tool rest clamp (4) that is hubbed on down tool rest (2) stage casing side, its leading portion of clamping does not make and can separate voluntarily easily when tool rest wedging up and down.Following tool rest inner face leading portion is established chute (22), and for placement blade bearing (5), and the inner face stage casing is provided with the storage groove (24) that the spacing tank (23) and that holds control cutter hub (6) provides spare blade to place; In addition, following tool rest stage casing side also is provided with the tool rest clamp perforation that (4) are pivoted (25) is provided.The inner face of upper cutter head then cooperate relative following tool rest inner face each device and design, and the outside front end is to convex with a card that must not break away from voluntarily arbitrarily in order to restriction tool rest clamp to end the slide rail (13) that flange (12) and provides the slippage of tool rest clamp.

The front of blade bearing (5) is provided with the stop convex body (51) in order to hook knot fixed blade, end side then links with a control cutter hub (6), the control cutter hub is camber arch and have suitable elasticity slightly, its hogback peak is to be provided with a protruding outer push button (61) of cutter that is exposed to, and push button cooperates spacing tank (23) to be fixedly arranged on the length that protrudes out of blade on the blade bearing (5) in order to control whereby.

The tangent plane of tool rest clamp (4) is the U shape, and integrally formed and tool elasticity slightly is hubbed on down the perforation (25) of tool rest stage casing side, and boring a hole with this is the center of circle, and along the slide rail (13) of upper cutter head and left and right sides pivot moves.

During use,,, only need earlier the tool rest clamp movingly and leave the tool rest up and down wedging state under, then, again upper cutter head is moved and leaves down tool rest to arrow b direction pivot according to arrow a direction pivot if need to change blade referring to Fig. 3 and Fig. 4.Like this, whole cutter promptly decomposes substantially, the blade that can directly more renew.If need gang tool, then only need to be undertaken by above-mentioned reverse procedure.When desire adjust blade protrude out length the time, only need directly press push button (61), or advance or move back with hand push, can reach its purpose.
