Tooth, the inside edge of the angulation support is provided with angle index, and the base is provided with horizontal line, and the center of the base is set
Angled pointer, the angle indicator is provided with arrow, and the arrow is oppositely arranged with angle index, the angle
The angle indicator that the top of pointer is provided with below block, the block is provided with below positioning sliding block, the positioning sliding block and set
There is latch on several, the upper latch matches with lower latch, covered on the angle indicator between the positioning sliding block and block
Holddown spring is connected to, the top of the holddown spring is connected with block, and bottom is connected with positioning sliding block.
Further, it is of the present utility model that there is positioning work(for the ease of promoting positioning sliding block to be slided up and down along angle indicator
Can pointer type protractor, the positioning sliding block is respectively arranged on the left side and the right side a fingerstall.
Further, for the ease of being held, the pointer type protractor of the present utility model with positioning function, the bottom
The lower section of seat is provided with a handle.
Further, in order to handle of holding with a firm grip, it is to avoid skid, the pointer angulation of the present utility model with positioning function
Device, decorative pattern of the outer wall provided with increase friction of the handle.
Further, the pointer type protractor of the present utility model with positioning function, between the angle indicator and base
It is hinged by pin.
The utility model obtain beneficial effect be：(1) it is simple in construction；(2) when specific measurement angle, survey crew one
Tight handle is held, the horizontal line on base is alignd with a line at angle, then the forefinger of an other hand and thumb is distinguished
Being inserted in two fingerstall, and enforce positioning sliding block overcomes the elastic force of holddown spring to be slided upwards along angle indicator, with
Positioning sliding block is moved up, and upper latch is gradually separated with lower latch, promotes angle indicator to turn using forefinger and thumb afterwards
Dynamic, when the other a line of angle indicator and angle coincides, angle indicator rotation is stirred in stopping, while fingerstall is unclamped,
Now positioning sliding block is moved down under the elastic force effect of holddown spring, until upper latch and lower latch clamping, angle indicator
Position is then locked, the arrow on last reading angular pointer to angle index, be the angle angle, using rise
Come very convenient, compared with existing protractor, the pointer type protractor of the present utility model with positioning function can not only lead to
Over-angle pointer indicates angle, while can be locked indicated angle index, thus is easy to lively show to student
The whole process of angular surveying, the method for being conducive to student quickly to grasp angular surveying；(3) left and right sides difference of positioning sliding block
Provided with a fingerstall, it is easy to driving positioning sliding block to slide；(4) whole angulation of holding with a firm grip is easy in the lower section of base provided with a handle
Device, decorative pattern of the outer wall provided with increase friction of handle, is easy to handle of holding with a firm grip, and avoids skidding.
