The specific embodiment
Core of the present utility model is to provide stapler under the mirror of a kind of chamber, and under this chamber mirror, the stability of stapler is higher.
In order to make those skilled in the art understand better the technical solution of the utility model, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 4-Fig. 8, in a kind of specific embodiment, stapler under the chamber mirror that this utility model embodiment provides, comprise device body, locking sleeve 12, block piece 18, spring 15, locking ball 14, suturing assembly 2.Gun barrel 1 is arranged on it device, the outer wall of gun barrel 1 be provided with step 16 and can with the block piece 18 of locking sleeve 12 butts, locking sleeve 12 is sheathed on gun barrel 1 outer wall, spring 15 1 ends and locking sleeve 12 butts and the other end and step 16 butts, the link of gun barrel 1 is provided with a plurality of bellmouths 13, be provided with locking ball 14 in bellmouth 13, the inwall of locking sleeve 12 is provided with and compresses boss 121 and compress boss 121 and can offset with locking ball 14, the inwall of gun barrel 1 is provided with the draw-in groove 191 paralleled with the gathering sill 19 of gun barrel 1, the link of suturing assembly 2 is provided with locking groove 22 and locking ball 14 can be positioned at locking groove 22.
When being installed on gun barrel 1 by suturing assembly 2, locking sleeve 12 is moved, thereby the compression boss 121 that makes locking sleeve 12 is removed the position of bellmouth 13, making to lock ball 14 can move, then by the boss of suturing assembly 2 21, the gathering sill 19 along gun barrel 1 inserts in gun barrel 1, after arriving gathering sill 19 bottoms, rotate then toward pulling back, the boss 21 of suturing assembly 2 is stuck in the draw-in groove 191 of gun barrel 1, and the position of the bellmouth 13 on this gun barrel 1 is corresponding with the locking groove 22 of suturing assembly 2, mobile locking sleeve 12 makes the compression boss 121 of locking sleeve 12 move to bellmouth 13 places, thereby making to compress boss 121 pushes against ball and makes ball be positioned at locking groove 22, spring 15 pushes against an end of locking sleeve 12 and block piece 18, make the position stability of locking sleeve 12, during dismounting, by this step, get final product on the contrary.Stapler under the chamber mirror that this utility model provides, thereby because pushing against ball, the compression boss 121 of locking sleeve 12 make ball push against suturing assembly 2, suturing assembly 2 can not rocked with respect to gun barrel 1, and the apparatus stable performance, improved the stability of stapler under the mirror of chamber.The boss 21 of above-mentioned suturing assembly 2 can be rectangular boss.Above-mentioned block piece 18 can be for being fixed on the projection on gun barrel 1.Outside and the end direct and locking sleeve 12 that spring 15 can be positioned at locking sleeve 12 connects.
In addition, under the mirror of chamber, the boss 21 of the installation end of the suturing assembly 2 of stapler is cylindrical, resistance when cylindrical boss can reduce suturing assembly 2 installation and removal, make suturing assembly 2 when installation or removal, cylindrical boss is more smooth in gathering sill 19 and the interior motion of draw-in groove 191 of gun barrel 1, more convenient while making suturing assembly 2 be installed on gun barrel 1.
In addition, the quantity of the bellmouth 13 on gun barrel 1 is 6, and when the quantity of bellmouth 13 is 6,6 balls that are arranged in bellmouth 13 can guarantee to have higher stability between stiching instrument assembly and gun barrel 1, now process and install all more convenient.
Further, the end of gun barrel 1 is provided with gun barrel groove 17, and block piece 18 is for being arranged at the circlip in gun barrel groove 17.Circlip can be more convenient be installed in gun barrel groove 17, also can be more convenient pull down, be convenient to change locking sleeve 12 and spring 15.
Further, spring 15 is positioned at the inside of locking sleeve 12, compression boss 121 butts of an end of spring 15 and locking sleeve 12.Spring 15 is positioned at locking sleeve 12 inside can make locking sleeve 12 protection springs 15, also avoids other foreign material to affect spring 15 normal operations, makes stapler safety and reliability under the mirror of chamber.
Preferably, the outer wall of suturing assembly 2 is provided with shield protrusion 23.Because suturing assembly 2 need to be pulled back with respect to gun barrel 1 when mounted, can leave certain gap between suturing assembly 2 and gun barrel 1, shield protrusion 23 can be lived with locking sleeve 12 butts of gun barrel 1, can shield gap, make the connecting surface between gun barrel 1 and suturing assembly 2 more smooth, thereby make stapler under the mirror of chamber in use can not scratch other foreign material, guaranteed the safety of operation process.
Above stapler under the mirror of chamber provided by the utility model is described in detail.Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from this utility model principle, can also carry out some improvement and modification to this utility model, these improvement and modification also fall in the protection domain of this utility model claim.
