The fixed ruler 1 is fixedly connected to the fixed ruler sleeve 2, and the sliding block 3 is slidably connected to the fixed ruler sleeve 2. The sliding block 3 is equipped with a locking mechanism 1 4 for locking the sliding block 3 onto the fixed ruler sleeve 2. The detection frame 5 is fixedly connected to the sliding block 3 and is used to specify the angle pointer on the scale 9. 8 passes through the detection frame 5 and the angle detection piece 6. The angle detection piece 6 is threaded with a screw for tightening the angle pointer 8. One end of the scale bracket 7 is fixed with a scale 9 for cooperating with the angle pointer 8. The other end of the scale bracket 7 is fixed to the sliding block 3. The sliding ruler sleeve 12 is fixedly connected to the movable ruler 13. Two positioning blocks 10 for fixing the detection piece 11 are slidably connected on the sliding ruler sleeve 12. The positioning blocks 10 are equipped with a locking mechanism 11 for locking the positioning blocks 10 on the sliding ruler sleeve 12. The fixed ruler 1 is fixed on the ruler frame 14, and the movable ruler 13 is slidably connected to the ruler frame 14.

[0027] As attached Figure 2 As shown, the fixed length sleeve 2 is provided with a square hole 21, a threaded hole 22, and a T-shaped rail 23. The fixed length 1 is sleeved in the square hole 21. A screw is threaded into the threaded hole 22. The fixed length sleeve 2 is fixedly connected to the fixed length 1 by the screw. The sliding block 3 is provided with a T-shaped groove 31, which is engaged with the T-shaped rail 23.

[0028] The sliding block 3 can slide freely in a straight line on the T-shaped rail 23 of the fixed length sleeve 2. When the sliding block 3 slides to the detection position, the locking mechanism 4 installed in the threaded hole of the sliding block 3 is tightened. The locking mechanism 4 will press against the fixed length sleeve 2, so that the sliding block 3 is fixed on the fixed length sleeve 2.

[0029] The locking mechanism 4 is a locking screw.

[0030] As attached Figure 3 As shown, the testing frame 5 consists of a square flange 51 and a column 52. The column 52 is vertically fixed to the end face of the square flange 51. The square flange 51 is provided with a threaded hole 53, and a screw is connected to the threaded hole 53. The square flange 51 is fixedly connected to the sliding block 3 by the screw. The outer side of the column 52 is provided with a center line groove 53 for centering. The column 52 is provided with a groove 54, and the angle detection piece 6 is placed in the groove 54. The column 52 is provided with a through hole 55 for the angle pointer 8 to pass through.

[0031] As attached Figure 4As shown, the angle pointer 8 is composed of a pointer needle body 81 and an insertion end 82 connected together. There is an included angle between the pointer needle body 81 and the insertion end 82. The insertion end 82 passes through the column 52 and the through hole on the angle detection plate 6.

[0032] As attached Figure 8 As shown, the angle detection plate 6 is provided with a through hole 61 for passing through the angle pointer 8 and a threaded hole 62. The threaded hole 62 is internally threaded with a screw for tightening the angle pointer 8.

[0033] The insertion end 82 of the angle pointer 8 can rotate within the through hole of the column 52 and the angle detection piece 6. When the angle pointer 8 is rotated to the correct position, the screw in the threaded hole 62 is tightened and pressed against the angle pointer 8, thereby fixing the angle pointer 8 and the angle detection piece 6 together.

[0034] When testing the included angle of a product, the tip of the angle pointer 8 moves on the scale 9. After the test is completed, the tip of the angle pointer 8 stops at a certain position on the scale line of the scale 9. By reading the scale value, the tested angle value can be obtained.

[0038] The positioning block 10 can slide linearly along the isolation space between the sliding sleeve 12 and the strip 123. After the positioning block 10 slides into place, the locking mechanism 11 on the threaded hole 103 is tightened, which fixes the positioning block 10 onto the sliding sleeve 12. These two positioning blocks 10 can clamp and fix the product being inspected, preventing it from moving during inspection. They can also support the strip 123, preventing it from deforming during inspection and affecting the inspection accuracy.

[0039] Locking mechanism 2, 11 is a locking screw.

[0040] The method of use of this application is as follows: During testing, the groove of the product to be tested is first installed in the strip 123, and then moved along the strip 123 to a suitable position. The product is then clamped by two positioning blocks 10 and tested. During testing, the movable ruler 13 is slowly pushed so that the curved surface of the product gradually contacts the angle detection plate 6. When the angle detection plate 6 is in complete contact with the curved surface of the product, the angle pointer 8 is fixed at a certain position on the scale 9. The scale value pointed to by the tip of the angle pointer 8 is the angle value to be tested.
