[0026] The utility model can use the first suction cup assembly 2 to fix the measuring body 1 on the computer screen. Then, after the plane diagram of the target angle measurement line is switched on the computer screen, the pointer 3 is driven to rotate and drive the second suction cup assembly 4, so that the indicating long groove 31 of the pointer 3 is aligned with the measuring line drawn on the computer using the plane diagram of the target angle measurement line, and the pointer 3 is fixed at the position of the computer using the second suction cup assembly 4. Then, the target angle of the bone group angle line in different planes can be quickly measured through the first angle scale line 12 of the measuring body 1.
[0027] See also Figure 2 In one embodiment, the measuring body 1 further includes second angle scale lines 14 along the semicircular direction of the semicircular hollow groove 11. The scale direction of the second angle scale lines 14, which range from 0 to 180 degrees, is opposite to the scale direction of the first angle scale lines 12. Furthermore, the semicircular hollow groove 11 is located between the first angle scale lines 12 and the second angle scale lines 14. However, this is not a limitation.
[0028] See also Figure 1 and Figure 2 In one embodiment, two linear hollow grooves 13 are symmetrically arranged on the measuring body 1 with the positioning center point as the center. However, the number of linear hollow grooves 13 is not limited thereto. For example, the number of linear hollow grooves 13 can also be one or three.
[0029] See also Figure 1 and Figure 2 In one embodiment, the linear hollow groove 13 is connected to the end of the semicircular hollow groove 11. However, this is not limited to the above. For example, in other embodiments, the linear hollow groove 13 may be configured not to be connected to the end of the semicircular hollow groove 11.
[0030] See also Figure 2 、 Figure 3 and Figure 6 In one embodiment, the first suction cup assembly 2 includes a first suction cup connecting rod 21, a first suction cup body 22, and a first suction cup retaining cap 23. The first suction cup connecting rod 21 is disposed through the measuring body 1. The first suction cup body 22 is connected to one end of the first suction cup connecting rod 21 and is located on the back side of the measuring body 1. The first suction cup retaining cap 23 is connected to the other end of the first suction cup connecting rod 21 and is located on the front side of the measuring body 1 and is used to retain the first suction cup connecting rod 21 on the measuring body 1. The first suction cup body 22 can be attached to the computer screen to secure the measuring body 1. However, the structure of the first suction cup assembly 2 is not limited to this.

The rotating shaft 15 is also provided with a sealing cap 16 for preventing the pointer 3 from falling off.
[0033] See also Figure 1 and Figure 7 In one embodiment, the second suction cup assembly 4 includes a second suction cup connecting rod 41, a second suction cup body 42 and a second suction cup limiting cap 43. The second suction cup connecting rod 41 is movably arranged on the indicating long groove 31 and the semicircular hollow groove 11 in a direction perpendicular to the measuring body 1. The second suction cup body 42 is connected to one end of the second suction cup connecting rod 41, and the second suction cup body 42 is located on the back side of the measuring body 1. The second suction cup limiting cap 43 is connected to the other end of the second suction cup connecting rod 41, and the second suction cup limiting cap 43 is located on the front side of the measuring body 1. The second suction cup limiting cap 43 is used to limit the second suction cup connecting rod 41. By pulling up the second suction cup limiting cap 43 of the second suction cup assembly 4, the second suction cup connecting rod 41 drives the second suction cup body 42 to move, thereby making the distance between the second suction cup body 42 and the computer screen greater than the distance between the first suction cup body 22 of the first suction cup assembly 2 and the computer screen, thereby allowing the pointer 3 to drive the second suction cup assembly 4 to move along the semicircular hollow groove 11 of the measuring body 1. By pressing the second suction cup limiting cap 43 of the second suction cup assembly 4, the second suction cup connecting rod 41 drives the second suction cup body 42 to move, thereby causing the second suction cup body 42 to move and adhere to the computer screen, thereby fixing the position of the pointer 3 and preventing the pointer 3 from shifting.
[0034] See also Figures 1 to 4 The measuring body 1 is a transparent structure, or a hollow structure 17 for observing the measuring line of the bone group angle line is provided in the middle of the measuring body 1. Figures 1 to 3 As shown, in one embodiment, a hollow structure 17 for observing the measurement line of the bone group angle line is provided in the middle position of the measurement body 1. The hollow structure 17 can be used to display the measurement line drawn on the computer using the plane diagram of the target angle measurement line, so that the doctor can quickly align the indicator slot 31 of the pointer 3 with the measurement line. Figure 4 As shown, in another embodiment, the measuring body 1 may also be a transparent structure, which can also facilitate the doctor to quickly align the indicating slot 31 of the pointer 3 with the measuring line.
[0035] In summary, the present invention's angle measuring device 100 for measuring bone group angles in different planes comprises a measuring body 1, a first suction cup assembly 2, a pointer 3, and a second suction cup assembly 4. By aligning the linear hollow groove 13 of the measuring body 1 with the baseline drawn on a computer using a baseline plane diagram, the first suction cup assembly 2 can be used to secure the measuring body 1 to the computer screen, ensuring that the measuring body 1 does not shift during the measurement process. After the computer screen switches to the target angle measurement line plane diagram, the pointer 3 is driven to rotate and drive the second suction cup assembly 4, so that the indicator groove 31 of the pointer 3 is aligned with the measurement line drawn on the computer using the target angle measurement line plane diagram. The pointer 3 is then secured to this position on the computer using the second suction cup assembly 4, ensuring that the pointer 3 does not shift during the measurement process. The target angles of the bone group angles in different planes can then be quickly measured using the first angle scale line 12 of the measuring body 1. Therefore, the present invention's angle measuring device 100 for measuring bone group angles in different planes can assist doctors in measuring angles such as femoral anteversion and humeral retroversion, which require the acquisition of angle lines in different planes.
