Detailed description of the invention
Below with reference to detailed description of the invention shown in the drawings, this utility model is described in detail.But these embodiments do not limit this utility model, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiments is all included in protection domain of the present utility model.
In this utility model, the word of described expression position and direction, is all using exercises on apparatus author as reference, is near-end near one end of operator, is far-end away from one end of operator.
Join Fig. 1 to Fig. 3, introduce a detailed description of the invention of this utility model straight line stitching instrument cutter sweep 100.In the present embodiment, this straight line stitching instrument cutter sweep 100 comprise can be mutually the closed or upper and lower clamp 101,102 opened.It should be noted that, here said " on ", D score do not represent locational absolute differentiation relation, and is only used to the convenience of describing.
In the present embodiment, nail bin hole 21 is to the far-end of nail bin 20 and is obliquely installed.Because wedge shape ejector pin portion 31 is what tilt with the mating surface of pushing slice of nail 40, in the time that its promotion pushing slice of nail 40 moves, the motive force being applied on pushing slice of nail 40 in fact also tilts, by nail bin hole 21 being set to tilt to the far-end of nail bin 20, can reduce pushing slice of nail 40 that be subject to not active force in the same way of nail bin hole 21 bearing of trends, reduce when pushing slice of nail 40 moves and the frictional force of nail bin hole 21 inwalls, pushing slice of nail 40 can be released more smoothly.
Wedge shape ejector pin portion 31 has the ejector pin face 32 that can coordinate with pushing slice of nail 40, and this ejector pin face 32 is with pushing slice of nail 40 direct effects and apply the active force vertical with ejector pin face 32 to pushing slice of nail 40.As preferred embodiment, in the present embodiment, nail bin hole 21 setting vertical with this ejector pin face 32, also be, the thrust direction that guarantee pushing slice of nail 40 is subject to is consistent with the bearing of trend in nail bin hole 21, frictional force when farthest reducing pushing slice of nail 40 and moving and between 21 inwalls of nail bin hole, to provide best ejector pin smooth degree.
In common straight line stitching instrument cutter sweep, the opposite face of nail anvil and nail bin is designed to opposed flattened, and in the time that doctor performs the operation, slip and skew to a certain degree may occur the destination organization being clamped between nail anvil and nail bin.Above-mentioned unfavorable in order to overcome, in the present embodiment, at the far-end of nail bin 20 in the direction of proximal extension, distance between upper surface 211 and nail bin 20 bottoms in nail bin hole 21 increases gradually arbitrarily, so, the surface of nail bin 20 is non-formation state by relative configurations, can make like this destination organization be held on more securely between nail anvil 10 and nail bin 20; Meanwhile, such design also agrees with the setting that in present embodiment, nail bin hole 21 tilts to nail bin 20 far-ends.
What can expect easily is; in the embodiment of replacing; upper surface that may nail bin hole is set to the heeling condition of other form; to reach and the similar technique effect of present embodiment; but these conversion all should be considered as the equivalents done in this utility model technological improvement, within it must be worked as and belongs to protection domain of the present utility model.
Coordinate with reference to Fig. 4, nail bin 20 comprises the cutting knife groove 22 arranging along its fore and aft axis, the nail bin hole 21 of any side adjacent columns of this cutting knife groove 22 is crisscross arranged, and such arranging is in the time that nail bin 20 and nail anvil 10 is closed equally, and destination organization is better clamped to effect.
Ginseng Fig. 5 and Fig. 6, distinguishingly, in the present embodiment, nail anvil 10 comprises the first nail anvil unit 11 and is individually fixed in 12, the first nail anvil unit 11, the second nail anvil unit and the second nail anvil unit 12 split manufactures of 11 both sides, the first nail anvil unit.It should be noted that, in the present embodiment, be the nail bin 20 with 4 row nail bin holes 21 be example, nail anvil 10 is set to comprise a first nail anvil unit 11 and two the second nail anvil unit 12 accordingly, in the embodiment of more replacements, for example have in the straight line stitching instrument cutter sweep in 6 row nail bin holes, need more the second nail anvil unit of relative set.
Due in the present embodiment, the nail bin hole of any side adjacent columns of cutting knife groove 22 is crisscross arranged, in order to reduce the molding difficulty of nail anvil, nail anvil is divided into the first nail anvil unit and the second nail anvil unit split manufacture, in actual production, the first nail anvil unit 11 and the second nail anvil unit 12 of split manufacture can be combined together by follow-up positioning welding, easy to assembly.
The nail bin hole 21 adjacent with cutting knife groove 22 setting that is mutually symmetrical on nail bin 20, such arranging can the corresponding molding difficulty that reduces the first nail anvil unit 11.Nail anvil 11 has the nail anvil forming surface relative with nail bin 20, this nail anvil forming surface and the first nail anvil unit 11 and the second nail anvil unit 12 corresponding part 111,121 undulates, nail bin 20 and nail anvil 10 apparent surfaces' overall flighting schedule arranges rule and even, ginseng Fig. 2, and, the surface that nail anvil forming surface is constructed to be provided with nail bin hole with nail bin 20 is engaged with each other, and farthest to reduce crowding-out effect, optimizes the clamping action to destination organization.
This utility model is by above-mentioned embodiment, there is following beneficial effect: the far-end that the straight line stitching instrument cutter sweep that this utility model provides is set to be to described nail bin by the nail bin hole in nail bin tilts, in the time that the pushing slice of nail in nail bin hole is pushed, it is subject to force direction consistent with the bearing of trend in nail bin hole, pushing slice of nail can not produce larger friction force with the inwall in nail bin hole, pushing slice of nail can be pushed more smoothly, reduce operating difficulty.
Be to be understood that, although this description is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present utility model; they are not in order to limit protection domain of the present utility model, all do not depart from the equivalent embodiment that this utility model skill spirit does or change and all should be included in protection domain of the present utility model within.
