Description
1, technical field
This utility model relates to test tool, specifically a kind of dissecting knife that has the broach shell that resets.
2, background technology
All there is the school duty room of oneself in now a lot of middle schools, such as chemical laboratory, physics laboratory, biology laboratory etc., finish the test course for students.Unexpected and injured phenomenon all can appear in experimentation unavoidably, and dissect in the course of animal at biologic test, the student does it yourself to finish the dissection process, the blade of the used dissecting knife of when dissected all is exposed to the outside mostly, do not pass through any safeguard procedures, be easy in the dissection process, hurt student's bacteria infection.Random being deposited in together deposited after test is finished, and also makes the blade damage blade that runs foul of each other easily, causes the unnecessary wearing and tearing of blade.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of dissecting knife that has the broach shell that resets is provided.
The technical solution of the utility model realizes in the following manner, a kind of dissecting knife that has the broach shell that resets, comprise blade, hilt, broach shell, blade is connected with hilt, the two ends up and down of hilt and blade junction hilt respectively are provided with the hanging head of projection, broach shell is enclosed within outside the blade, end near point of a knife place broach shell has an opening, the other end is provided with concave edge, concave edge is relative up and down with hanging head, extension spring is arranged between hanging head and the concave edge, and two of extension spring is connected with concave edge with hanging head respectively, and the hilt surface is provided with anti-skidding stricture of vagina.The afterbody of hilt is provided with a circular hole that crosses the hilt sidewall.Opening is vertical with blade.
This utility model is by the flexible connection of broach shell and cutter hub; make the broach shell slip that can reset; neither influence the depth of when dissected blade cuts; do not separate Section line but also can not block, can also play protection operator's effect simultaneously, the operator can accidentally not injured by blade in the dissection process; exactly after using; clean also easily, utilize the hole of hilt afterbody to insert to hang to deposit not only and conveniently take, also easy damaged blade not.Has advantage simple in structure, easy to use, reasonable in design.
