Abstract
The utility model discloses a slicer knife rest, comprising a blade (1), a blade clamping plate (2) for fixing the blade (1), a trigger guard (3) arranged on the blade clamping plate (2) and used for protecting the blade (1) and a fixed seat (4) for fixing the blade clamping plate (2). A finger protecting device is arranged between the front upward side of the blade (1) next to the blade clamping plate (2) and a specimen fixed frame (5). The utility model has the advantages of simple structure and easy use, can prevent the fingers of an operator from being scratched by the blade in the process of operation, and reduces the risk of operation.
Description
Technical field
The utility model relates to a kind of pathological section machine, particularly a kind of microtome kinfe holder.
Technical background
The existing knife rest that is used for the microtome of Pathologic specimen section, comprise blade, be used for fixing blade the blade clamping plate, be arranged on and be used to protect protecting bow and being used for fixing the holder of blade clamping plate of blade on the blade clamping plate,
Gap between sample fixed mount and the blade makes operator's finger be easy to touch blade, and the operator is easy to by cut wound.
Summary of the invention
The microtome kinfe holder that provides a kind of operator of protection to point is provided the purpose of this utility model.
The purpose of this utility model is to realize by such technical scheme; a kind of microtome kinfe holder; comprise blade, be used for fixing blade the blade clamping plate, be arranged on and be used to protect protecting bow and being used for fixing the holder of blade clamping plate of blade on the blade clamping plate, between blade front upper place on next-door neighbour's blade clamping plate and sample fixed mount, be provided with the finger protection device.
Further, described finger protection device comprises backplate and fixed support, and backplate is connected with holder by fixed support; Wherein, described fixed support comprises pivoted arm and the grip block that is arranged in pairs in the holder both sides, and an end of pivoted arm is connected with holder, and the other end is connected with grip block, and described backplate is fixed between two grip blocks.
In order to prevent that finger from being scratched by blade, described backplate is provided with a slit between the side cut of the edge of blade and blade, and the breadth extreme in described slit is lower than the width of finger.
Described backplate and blade face extend in parallel with keeping at a distance.Preferably select the same with adjustable maximum slice thickness on microtome in this cutting planes and the distance between the backplate.
In order better to observe working angles and to judge the section of downcutting, described backplate is made by material transparent.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to use, it can prevent that operator's finger from being scratched by blade in operating process, reduced the danger of operation.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the simplification sectional view of knife rest.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment: as shown in Figure 1, 2; a kind of microtome kinfe holder; comprise blade 1, be used for fixing blade 1 blade clamping plate 2, be arranged on and be used to protect protecting bow 3 and being used for fixing the holder 4 of blade clamping plate 2 of blade 1 on the blade clamping plate 2, between blade 1 front upper place on next-door neighbour's blade clamping plate 2 and sample fixed mount 5, be provided with the finger protection device.Wherein, described finger protection device comprises backplate 6 and fixed support, and backplate 6 is connected with holder by fixed support.Described fixed support comprises pivoted arm 7 and the grip block 8 that is arranged in pairs in the holder both sides, and an end of pivoted arm 7 is connected with holder 4, and the other end is connected with grip block 8, and described backplate 7 is fixed between two grip blocks 8.
Described backplate 6 is provided with a slit 9 between the side cut of the edge of blade 1 and blade 1, the breadth extreme in described slit 9 is lower than the width of finger, and this width makes the operator's finger joint can not touch the side cut of blade.
Described backplate 6 extends in parallel with blade 1 surface with keeping at a distance, preferably selects the same with adjustable maximum slice thickness on microtome in this cutting planes and the distance between the backplate.
Described backplate 6 is made by material transparent, and transparent material described here can be transparent plastics, also can be clear glass.
Present embodiment includes but are not limited to this, as long as microtome is provided with the finger protection device, all drops in the protection domain of the present utility model.
