The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Consult shown in Fig. 2 to Fig. 8, a kind of perching knife, it comprises knife rest, handle 20, on knife rest, be provided with link slot, link slot middle part is provided with internal thread 11 to inner sidewall, one end of handle 20 is link 20a, on the outer wall of link 20a, be provided with external screw thread 21, external screw thread 21 mates with internal thread 11, knife rest comprises tool holder body 10 and mosaic block 30, in tool holder body 10, be provided with opening 14, the form fit of the shape of opening 14 and mosaic block 30, mosaic block 30 and opening 14 clampings, link slot is distributed on the inwall of mosaic block 30 and the inside wall of tool holder body 10.By the integrated knife rest of script, change into by tool holder body 10, mosaic block 30 forms, link slot is distributed on the inwall of mosaic block 30 and the inside wall of tool holder body 10, be that internal thread 11 is distributed on the inwall of mosaic block 30 and the inside wall of tool holder body 10, by coordinating of internal thread 11 and external screw thread 21, mosaic block 30 and tool holder body 10 screw threads are fixed on the link 20a of handle 20, because knife rest is not integrated, do not need the threaded core 60a of side direction structure, when patrix 41 and counterdie 42 die sinking, only need a side core 60b of a 10mm, can increase the life-span of mould, produce more for convenience, reduced cost.
Wherein, mosaic block 30 with the concrete structure of opening 14 clampings is: on mosaic block 30, be provided with at least one buckle 31, in opening 14, be provided with at least one draw-in groove 13, the quantity of buckle 31 is consistent with the quantity of draw-in groove 13, the form fit of the shape of buckle 31 and draw-in groove 13, each buckle 31 can be fastened in the draw-in groove corresponding with it 13.When mosaic block 30 is installed, first mosaic block 30 is aimed to opening 14, again at least one buckle 31 is aimed at least one draw-in groove 13, with X1 direction slip mosaic block 30, until buckle 31 snaps in the draw-in groove corresponding with it 13, realize clamping, last turn handle 20, realizes fixedly mosaic block 30 by the external screw thread 21 on handle 20 and the internal thread 11 on the inwall of mosaic block 30 and the inwall of tool holder body 10.
General knife rest screw thread is fixed on after handle 20, be easy to occur loosening, in order to address this problem, on the outer wall of the link 20a of the present embodiment, be provided with groove 23, in groove 23, be provided with latch segment 22, latch segment 22 is skewed, latch segment 22 has fixed end and perk end 22a, fixed end is fixedly connected with groove 23 diapires, between perk end 22a and groove 23 diapires, there is distance, the outer wall of fixed end is equal to or less than the radius of link 20a to the distance of the central axis of link 20a, the outer wall of perk end 22a is greater than the radius of link 20a to the distance of link 20a central axis, in tool holder body 10, be provided with stopper slot 12, the form fit of the shape of stopper slot 12 and latch segment 22, latch segment 22 has elasticity, latch segment 22 can be to the diapire motion of groove 23, when handle 20 is not connected with knife rest, distance between the outer wall of the outer wall of latch segment 22 and link 20a is greater than the degree of depth of groove 23.When the link 20a of handle 20 will soon screw home with knife rest, stopper slot 12 just contacts with the perk end 22a of latch segment 22, while not being connected with knife rest due to handle 20, distance between the outer wall of the outer wall of latch segment 22 and link 20a is greater than the degree of depth of groove 23, perk end 22a is subject to the extruding of stopper slot 12, to the diapire motion of groove 23, until perk end 22a snaps in stopper slot 12 completely, now the elastic force of latch segment 22 provides coupling mechanism force at this.
Stopper slot 12 in the present embodiment is arranged on the inside wall of link slot oral area.
Wherein, external screw thread 21 is distributed on the outer wall of fixed end and the outer wall of link 20a.
The material of latch segment 22 is plastics.When external force is applied on latch segment 22, can there is certain deformation.
The length of stopper slot 12 is greater than the length of the perk end 22a of latch segment 22, stopper slot 12 has a end 12a, b end 12b, perk end 22a embeds a end 12a of stopper slot 12, and one of them draw-in groove 13 is the b end 12b of stopper slot 12, and one of them buckle 31 can embed the b end 12b of stopper slot 12.Stopper slot 12 both can be locked latch segment 22, also can be used as the draw-in groove 13 coordinating with 31 clampings of one of them buckle, had reduced the quantity of draw-in groove 13, had then reduced cost.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
