[0010] As a preferred solution, the second cover plate and the first cover plate are hingedly connected together through a hinge.

[0011] As a preferred solution, the mold body is made of silica gel.

[0012] The utility model discloses have obvious advantages and beneficial effects compared with prior art, specifically speaking, from the above technical scheme can know:

[0013] By forming the accommodating groove for accommodating the RF antenna plate on the second cover plate, and cooperating with the earphone groove adapted to the earphone formed on the mold body, and the mold body having the connecting part connected with the artificial ear, the jig can be used for RF test and acoustic performance test, two work stations are combined into one, and the test can be carried out individually, or the test can be carried out simultaneously through two channels, without the need for separate operation, which brings convenience to the detection personnel, improves the operation efficiency, and reduces resource waste.
