Abstract

The improvement of the structure of a sliding bottom of an art designing broaching tool mainly uses the sliding bottom of a broaching tool comprising a body, a spring, a piece of shrapnel for pushing and jamming the knife and a pushing button. Through the firm location of the shrapnel in the holding groove combines with the design of the overhanging edge in the center of the shrapnel propped up firmly by the spring, the overhanging edge can be propped up and jammed in the slide track of the right groove for jamming the knife, improving the anti-pushing strength of the sliding base of the broaching tool to avoid the loosening and sliding phenomenon when the blade imposes force. According to the prior art, the elasticity fatigue, loosening and distortion can appear after the shrapnel is used a period of time, causing the transitional slide of the blade in the process of cutting, and now the shortcoming is overcome by the utility model.

Description

The structural improvement of cutter push broach slide

Technical field

The utility model relates to a kind of art designing's cutter, refers to a kind of structural improvement of cutter push broach slide especially.

Background technology

In the combination of numerous stationery, cutter is everybody indispensability, and quite general and practical, and indispensable instrument.

See also Fig. 1, shown in 2, it is " CUTTERKNIFE " patent case of No. the 6226873rd, United States Patent (USP) number, the main exposure has a kind of cutter 10 structures, it roughly includes the toggle 11 of a tool slide rail 111, this toggle 11 is except that providing blade 12 and push broach slide 13 to install to be nested with, the user also can be provided the gripping application of force when cutting operation, wherein but this push broach slide 13 includes the body 131 of embedding cunning in toggle 11 slide rails 111, be slidingly equipped with a push button 132 with body 131 upper limits, these push button 132 top sides are formed with a wedge-shaped slot 132A, it is wherein ccontaining to support edge 133A for clip shell fragment 133 central projections of installing in the body 131 storage tank 131A, and the central projection of this clip shell fragment 133 supports edge 133A when normal condition, but system's elasticity is resisted against among the suitable clamping slot 111A of slide rail 111, make this push broach slide 13 fasten the location mutually with toggle 11, and when passing push button 132 before and after the user, system can be by push button 132 the inclined-plane of the wedge-shaped slot 132A prominent edge 133A of supporting that presses clip shell fragment 133 do to contract in flexible, and by the prominent clamping slot 111A that supports slide rail 111 in the edge 133A disengaging, the blade 12 that makes push broach slide 13 get the connection of interlock front end is made elastic displacement location.

Above-mentioned prior art cutter structure; though can do elastic slippage and suitably locate by push broach slide control interlock blade; but this push broach slide only depends on the elastic-restoring force of clip shell fragment itself; central knuckle portion elasticity is resisted against in the clamping slot of slide rail; as push broach slide and toggle to fasten location structure still desirable not to the utmost; reason is: general clip shell fragment is after using a period of time or some number of times; all can produce elastic fatigue and relaxation; especially the access times of blade are all the more frequent; its phenomenon is more for obvious; and when this phenomenon takes place; the push broach slide just can't positively be snapped on the toggle; so that force in blade when carrying out various cutting operation when the user compresses, regular meeting's generation blade is snaps into position and the phenomenon that contracts in producing firmly, and influences the cutting usefulness of cutter.Except that this, clip shell fragment two ends only connect and are butted on the storage tank root edge, and it is spacing that its two ends are not subjected to butt, and the therefore easier deflection of clip shell fragment that makes strengthens, cause elastic fatigue or distortion incidence to raise, can influence the location intensity and the usefulness of push broach slide and toggle equally.

Summary of the invention

Technical problem to be solved in the utility model is to overcome existing defective in the above-mentioned prior art, and a kind of structural improvement of cutter push broach slide is provided

The utility model has adopted following technical proposal to solve its technical problem: a kind of structural improvement of cutter push broach slide, this cutter includes a toggle, blade, the push broach slide with support stops, wherein edge is formed with a slide rail respectively about this toggle one side, and the upper limb slide rail is provided with clamping slot, but the proper embedding cunning of this push broach slide is positioned, in the glidepath, push broach slide front end connects a blade, make the blade must be with push broach slide slippage interlock and location, the toggle rear end be equipped with one with retreat slippage as the push broach slide spacing replace support stops, it is characterized in that: this push broach slide also includes:

One body, it is to be formed with an embedded and slide part, with and set in the upper and lower slide rail that is slidedly arranged on toggle, and be convexly equipped with the holding part of a tool storage tank in the embedded and slide part lateral border, this storage tank root edge centre convexes with a reference column, the top line of corresponding reference column is formed with a breach, and lower wall edge place respectively convexes with embeded edge on holding part in addition, respectively is concaved with a stopper slot in the external end edge central sections;

One spring, it is to be placed on the root edge reference column of above-mentioned body storage tank, so that back stretch to be provided;

One clip shell fragment, it is Π font sheet body structure, and in the curved protruding prominent edge that supports that has of top flat central authorities, after making this clip shell fragment be placed in the storage tank of above-mentioned body, two lateral plates just can paste with the two side edge of storage tank and support the location, central projection supports the edge inner edge then can form a spring tank, holds for spring and stretches and the top is replaced, and this prominent apical margin is that ccontaining clip forms firm clip positioning states in the clamping slot of toggle upper and lower slide rail:

One push button, it is the embedding sleeve shape body structure of pulling, and form a passing face in the outer wall edge, in interior sorrowful formation one embedding slot, but in notch up and down edge form a proper embedding cunning respectively and be fastened on the above-mentioned body, following embeded edge collude edge, make this push button must nested slippage on the body holding part, the embedding slot root edge is convexly equipped with a flange surface, make this flange surface two side edge just available in the stopper slot of body, in stopper slot, make the front and back locating slip with the restriction push button, the central sections that other push button upside colludes edge is concaved with a wedge-shaped slot, making dashing forward of clip shell fragment support edge just can be wherein ccontaining, and the power that presses downwards that produces can be subjected to displacement before and after the wedge-shaped slot time, the related spring that presses downwards forms flexible recessed shape attitude.

Compared to the prior art, the prominent edge that supports of the utility model clip shell fragment is except that supporting to arrive in the clamping slot that is snapped in slide rail with the flexible structure of institute tool own, also nationality helps the spring restoring force to replace the prominent spring tank that supports the edge bottom simultaneously, what make firmly fastens in the clamping slot of last slide rail, even the prolonged use of clip shell fragment produces elastic fatigue, still but nationality helps the spring restoring force to remain in full snaps into position state, these clip shell fragment both sides directly are resisted against body storage tank two side edge in addition, also can slow down the clip shell fragment and produce elastic fatigue, increase the power that supports simultaneously, improve the tightness and the persistence of snaps into position between push broach slide and toggle, and then guarantee the performance of cutter cutting usefulness.
