Wherein, described left cover and right cover plate are all fastened on by the web member be connected with chi face side on chi face in a non-operative state, in working order under can open around web member, described left cover and right cover plate are provided with towards the plate face in chi face the light emitting source imposing illumination.
And radial direction one side of described chi body is provided with battery case and two-way switch, described light emitting source by two-way switch be arranged on accumulator in battery case and be connected and obtain and power; Top and/or the bottom of described chi body are provided with limited block, carry out spacing when being fastened on chi face for left cover and right cover plate.
The utility model is set to further: the radial dimension of described left cover and right cover plate is equal to the long half of chi face diameter.
The utility model is set to further: described groove is U-shaped.
The utility model is set to further: described limited block is distributed in the centre, top of chi body and protrudes place, chi face plane, comprises the fixed part be connected with chi body top and the spacing edge of protruding chi face; The plate face that described left cover and right cover plate contact with spacing edge is provided with the breach matched with spacing edge.
The utility model is set to further: the medial surface on described spacing edge is provided with the 3 row's illuminating lamps imposing illumination towards scale.
The utility model is set to further: described 3 row's illuminating lamps are the lamp body of 3 kinds of colors.
Compared with prior art, the beneficial effect that the utility model has is:
By the setting of the left cover and right cover plate and limited block that are provided with light emitting source, wherein left cover and right cover plate to be all fastened on by the web member be connected with chi face side in a non-operative state on chi face, in working order under can open around web member, limited block carries out spacing when being fastened on chi face for left cover and right cover plate, lighting angle can be realized adjustable, and provide uniform and stable light after regulating according to measurement requirement, guaranteeing can be well at dark environment measures accurately, saving manpower is paid, and increases work efficiency; Graduated for drafting chi face given in a non-operative state protection simultaneously and there is fastening limit function, making chi face be able to abrasionproof and increase the service life.
Foregoing is only the general introduction of technical solutions of the utility model, and in order to clearer understanding technological means of the present utility model, below in conjunction with accompanying drawing, the utility model will be further described.
