Specific embodiment
The utility model is described further with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, Linear cutting anastomat comprising the front end of shell 1, shell 1 is equipped with resist-nailed seat 11,
Being equipped in the shell 1 can slide with respect to shell, the activity percussion module 2 for being positioned and being fired to nail bin, described
The driving assembly 3 that driving activity percussion module generates sliding is additionally provided on shell 1, the upper surface of the shell 1 is equipped with sliding
Block 4, sliding shoe 4 are connected with the locating rod 41 positioned to resist-nailed seat and nail bin 13, and the shell 1 is equipped with and can slide
Feeding jam plate 12, the end of feeding jam plate 12, which is equipped with, is caught in the latch segment 121 that driving assembly is locked, and feeds on jam plate 12
There is sliding groove 122, the lower surface of sliding shoe 4 is equipped with the protrusion 42 cooperated with sliding groove.
In the utility model equipment in a state of nature when, the latch segment for feeding jam plate locks driving assembly, people
Activity percussion module can not be driven to be moved forward and backward by driving assembly, only first moved in sliding shoe, make locating rod to supporting
After nail seat and nail bin are positioned, sliding shoe movement drives feeding jam plate movement, separates feeding jam plate with driving assembly, this
When, people can just drive the Forward of activity percussion module by driving assembly, i.e., only in locating rod to resist-nailed seat and nail
After storehouse is positioned, nail bin can move forward, and ensure that nail bin moves forward is not in the pendulum of downward shift or left and right in the process
Dynamic, the position of nail bin and resist-nailed seat is stablized, so that preferable sewing effect could be obtained.
Feeding jam plate 12 as shown in Figure 4, the surface for feeding jam plate are equipped with sliding groove 122, and end forms a latch segment
121, two sides are equipped with guiding parts and are fitted on the inner wall of the housing, are oriented to its sliding relative to shell, are located at sliding groove
Side be equipped with solution lockhole 123.
