It sets and is vertically and fixedly provided with stud 3, stud 3 is fixed after passing through diamond shape slot by nut 4；Far from semicircle bevel protractor on 2 slotted guide tracks 2
1 one end sets adsorption magnet 5 respectively, and adsorption magnet 5 is at least 4, is equally divided into 2 groups, every group of adsorption magnet 5 is adsorbed on respectively
There is 4 fixed one side of nut on 1 slotted guide tracks 2, and every group of adsorption magnet 5 is set along the longitudinally spaced of corresponding slotted guide tracks 2
It sets.
The material of the semicircle bevel protractor 1 is austenitic stainless steel, which is provided with 0 °~180 ° of angle index.
The slotted guide tracks 2 are rectangle steel plate, and thickness is 0.1~0.5mm, and material is straight carbon steel.
The width of the adsorption magnet 5 is more than or equal to the width of slotted guide tracks 2.
A kind of each component part of steel bend test angular instrument described in the utility model and its effect are as follows：
1) semicircle bevel protractor 1；For angles of display, generally semi-circular shape, material is austenitic stainless steel, in side table
It is carved with 0 °~180 ° of angle index in face.In the central coordinate of circle origin position of semicircle bevel protractor 1, a stud 3, stud are vertically fixed
3 lower half portion is cylinder, can be slided in the elongated guide groove of slotted guide tracks 2,3 top half surface of stud carries
External screw thread is fixed for coordinating with nut 4.
2) slotted guide tracks 2；2 are set altogether, are rectangular sheet metal, material is straight carbon steel.The middle part of slotted guide tracks 2 processes
The width of elongated guide groove, elongated guide groove is matched with the cylinder diameter of 1 upper stud of semicircle bevel protractor, 3 lower part, ensures 3 edge of stud
While elongated guide groove sliding, its motion track is limited, plays position-limiting action.
3) adsorption magnet 5；Using the strong magnets of at least four cuboid, width is not less than the width of slotted guide tracks 2.
By taking 4 adsorption magnets 5 as an example, wherein 2 adsorption magnets 5 are adsorbed on a slotted guide tracks 2, in addition 2 are adsorbed on another
