Detailed description of the invention
In description of the present utility model, it will be appreciated that, term " on ", D score, "front", "rear", "left", "right", " top ", " end " " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In the utility model, unless otherwise clearly defined and limited, the term such as term " installation ", " being connected ", " connection ", " fixing " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood as the case may be.
In the utility model, unless otherwise clearly defined and limited, fisrt feature second feature it " on " or D score can comprise the first and second features and directly contact, also can comprise the first and second features and not be directly contact but by the other characterisation contact between them.And, fisrt feature second feature " on ", " top " and " above " comprise fisrt feature directly over second feature and oblique upper, or only represent that fisrt feature level height is higher than second feature.Fisrt feature second feature " under ", " below " and " below " comprise fisrt feature immediately below second feature and tiltedly below, or only represent that fisrt feature level height is less than second feature.
As shown in figs. 1 and 3, a kind of flexible cutter, comprises up knob 1, cutter head 2, spring 4, spring anchorage bracket 5, slide block 6 and lower handle 9; Described up knob 1 is connected with described lower handle 9 revolute pair.
As shown in Figure 2, described up knob 1 inside is connected with spring stop 12, described spring anchorage bracket 5 is through described spring stop 12, one end of described spring anchorage bracket 5 is fixedly connected with cutter head fixed mount 3, the other end is fixedly connected with described slide block 6, described spring 4 is enclosed within described spring anchorage bracket 5, and one end of described spring 4 is against on described spring stop 12, and the other end is against on described slide block 6.
