[0031] See also Figure 1 The positioning fixture provided in the embodiment of the present application is now described. The positioning fixture provided in the embodiment of the present application is used to position a notebook housing, the notebook housing including a bottom housing and a back housing connected to the bottom housing, including:

[0032] A bottom plate assembly 1, used for supporting the bottom shell of the notebook housing;

[0033] A back panel assembly 2, mounted on the bottom panel assembly 1, for supporting the back shell of the notebook housing;

[0034] The fixing assembly 3 is mounted on the bottom plate assembly 1, and comprises an elastic member 31, an abutting member 32 and a stopper 33. The stopper 33 is mounted on a side of the bottom plate assembly 1 away from the back plate assembly 2. The abutting member 32 is movably mounted on the bottom plate assembly 1. The abutting member 32 is arranged between the back plate assembly 2 and the stopper 33. The elastic member 31 is arranged between the abutting member 32 and the stopper 33.

[0035] The abutment member 32 is moved toward the direction approaching the stopper 33 to avoid the bottom shell of the notebook case so that the bottom shell of the notebook case can be placed on the bottom plate assembly 1; when the bottom shell of the notebook case is placed on the bottom plate assembly 1 and the back plate assembly 2 supports the back shell of the notebook case, the abutment member 32 is released, and the elastic member 31 pushes the abutment member 32 to move toward the back plate assembly 2, so that the abutment member 32 abuts against the side wall of the bottom shell of the notebook case, so that the bottom shell of the notebook case is fixed on the bottom plate assembly 1.
