[0029] The arm shaft 1 can only rotate.

[0030] Two groups of joint shell 2 side walls at both ends are respectively provided with a light inlet 5 and a light outlet 501; the joint shell 2 at one end of the light inlet 5 is fixedly connected with a connecting plate 601, and the connecting plate 601 is provided with a fixing hole.

[0031] The light guide arm disclosed in the embodiment further comprises a rod 701; the joint shell 2 at one end of the light outlet 501 is fixedly connected with the rod 701; and the rod 701 is fixedly connected with a magnetic table seat 7 at an end away from the light outlet 501.

[0032] The rod 701 is a telescopic rod, and the length can be adjusted.

[0033] In use, according to the position of the laser system, the light inlet 5 is aligned with the generating end of the laser system, then the position of the light inlet 5 is fixed through the connecting plate 601, and is fixed on the test table, then according to the test requirements, any one group of arm shafts 1 can be rotated at will, because the adjacent two arm shafts 1 are 90°, and the arm shaft 1 is designed in multiple groups, therefore, the light outlet 501 can be adjusted to any position at will according to the needs, and then the length of the rod 701 is adjusted and is fixed on the test table through the magnetic force table seat 7.
