Abstract
The utility model relates to an index head and particularly relates to an accurate positioning index head. The accurate positioning index head comprises an index plate and a pore ring, wherein the pore ring passes through and is distributed on the outer circle of the index plate, and a degree distribution table is arranged on the inner circle of the index plate. The accurate positioning index head can be used for more accurately and directly displaying a reading result and students can more easily accept the teaching content in class.
Description
Technical field
The utility model relates to a kind of dividing head, especially a kind of accurate location dividing head.
Background technology
Existing universal dividing head has only tiny intensive hole circle, does not divide kilsyth basalt and the number of degrees are set, and the fixed number that when teaching is used, shows is not directly perceived,, the student is harder when observing, and it is not high that traditional index plate is used for Teaching Quality.
The utility model content
Not not enough intuitively in order to overcome the existing index plate number of degrees, the utility model provides a kind of accurate location dividing head.
The utility model solves the technical scheme that its technical matters adopted: a kind of accurate location dividing head, comprise index plate and Kong Quan, and the hole circle runs through and is distributed in the outer ring of index plate, and the index plate inner ring is provided with number of degrees distribution table.
The beneficial effect of the utility model is, uses this dividing head can show reading more accurately, intuitively, can easierly accept the content of courses when letting the student at school.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
1. index plates among the figure, 2. hole circle, 3. number of degrees distribution table.
Embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of accurate location dividing head comprises index plate 1 and hole circle 2, and hole circle 2 runs through and be distributed in the outer ring of index plate 1, and index plate 1 inner ring is provided with number of degrees distribution table 3.
Because being provided with the number of degrees, the inner ring of index plate 1 divides kilsyth basalt 3; Each hole circle 2 has all marked position and reading on the outer ring of 3 pairs of index plates 1 of kilsyth basalt and the number of degrees divide;, the student just can directly obtain a result when carrying out a some hole like this according to the reading on the number of degrees minute kilsyth basalt 3; Use this dividing head can show reading more accurately, intuitively, can easierly accept the content of courses when letting the student at school.
Claims (1)
1. accurately locate dividing head for one kind, comprise index plate (1) and hole circle (2), hole circle (2) runs through and is distributed in the outer ring of index plate (1), it is characterized in that index plate (1) inner ring is provided with number of degrees distribution table (3).
