The specific embodiment
Core of the present utility model provides the safety of stapler under the mirror of a kind of chamber, and these safety have improved the disposable staple casket success rate in use of stapler under the mirror of chamber.Another core of the present utility model provides stapler under a kind of chamber mirror that comprises above-mentioned safety.
In order to make those skilled in the art understand the technical solution of the utility model better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 2-Figure 11, in a kind of specific embodiment, the safety of stapler under a kind of chamber mirror that this utility model provides, comprise safety block assembly 1 and nail casket housing, safety block assembly 1 comprises safety block 11, contiguous block 13 and safety block shell fragment 12, and nail casket housing comprises nail casket base 21 and nail casket upper casing 22.Safety block assembly 1 is installed on the cutter 5 of stapler under the mirror of chamber and is positioned at disposable staple casket 2, and the trigger shaft of stapler is connected under an end of cutter 5 and the chamber mirror, and the nail supporting base of stapler is connected under the other end and the chamber mirror.The sidewall of nail casket base 21 is provided with two steps 4, and the bottom of nail casket base 21 is provided with two pedestal lobes 6.Safety block 11 is provided with safety block projection 111, and nail casket housing is provided with and stops projection 3, stops that projection 3 and the closing end of the step 4 of nail casket housing are oppositely arranged.When stiching instrument was closed, safety block 11 was positioned at an end of step 4, and this end of step 4 is the closing end of step 4.Safety block projection 111 can be arranged on the bottom of safety block 11, stops that projection 3 can be arranged on the step 4 of nail casket base 21.
Stapler is when work under the chamber mirror that this utility model embodiment provides, under the mirror of chamber during the stapler original state, safety block 11 is positioned on the step 4 of nail casket housing, safety block 11 travels forward at step 4, when safety block 11 advances to the closing end of step 4, set safety block projection 111 is positioned at a set side that stops projection 3 on the nail casket housing on the safety block 11 at this moment, and and its offset, safety block 11 moves forward, safety block projection 111 is pushed mutually with stopping projection 3, safety block projection 111 is crossed and is stopped that projection 3 advances to the opposite side that stops projection 3, produce vibration, thereby produce the feel prompting, stapler enters closure state under the mirror of chamber, and then carries out next step operation.
By foregoing description as can be known, with respect to the above-mentioned background technology, the safety of stapler under the chamber mirror that this utility model provides, owing to be respectively arranged with safety block projection 111 and stop projection 3 at safety block 11 and nail casket housing, thereby produce a feel prompting when making safety block 11 move to the closing end of step 4, make the operator recognize that safety block 11 has fallen step 4, if retreat this moment, disposable staple casket 2 will be scrapped, the operator can operate accurately according to judging accurately, avoid maloperation, thereby improved disposable staple casket 2 success rate in use of stapler under the mirror of chamber.
In addition, safety block projection 111 is arranged at the both sides of safety block 11, stops that projection 3 is arranged on the sidewall of nail casket housing.When safety block projection 111 cross stop protruding 3 the time, safety block 11 stressed more reliable, the motion stabilization of safety block 11, the operator's that is more convenient for operation also makes the operator experience the feel prompting of safety more sensitively.
In addition, stop that projection 3 is arranged on the nail casket upper casing 22 of nail casket housing.At nail casket upper casing 22 projection is set and is more convenient for processing, and less to the integral body transformation of nail casket housing, production cost is lower.
Further, the material of nail casket upper casing 22 is plastics.When the material of nail casket upper casing 22 was plastics, the processing of being more convenient for stopped projection 3, and plastics have certain ductility, and safety block projection 111 is easier to cross and stops projection 3, under the prerequisite that the feel prompting is arranged, is convenient to operator's operation more.
Further, safety block projection 111 and/or stop that projection 3 is the fillet projection.When safety block projection 111 and/or when stopping projection 3 for the fillet projection, safety block projection 111 is easier to cross and stops projection 3, and the operation of safety block 11 is more steady, makes under the mirror of chamber stapler be convenient to operation more.
The above-mentioned safety that stapler comprises trigger shaft and is connected with trigger shaft under the chamber mirror that this utility model embodiment provides, the structure of other parts can be with reference to prior art, and this paper repeats no more.
More than stapler and safety thereof under the mirror of chamber provided by the utility model are described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used 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.
