The two rotating shafts are respectively inserted into the two rotating holes, and when the swing arm rotates to face the left side, the swing arm and the hook head cooperate with each other.
[0010] The beneficial effects of the above scheme are as follows: a plurality of through holes for the passage of bolts are provided on the left base plate, and the left base plate is connected to the cabinet body by bolts. When the swing arm rotates to the initial state, the hook head can be hooked with the swing arm, and the swing arm is rotated so that the swing arm rotates to the other side. At this time, the swing arm pulls the hook head until the two cabinet sides are fitted together.
[0011] The above-mentioned test frame locking structure also has the following characteristics: the rotary arm includes a first bearing plate, a second bearing plate and a middle support plate, the first bearing plate and the second bearing plate are respectively arranged on both sides of the middle support plate, and the two rotating shafts are respectively arranged on the side of the first bearing plate and the second bearing plate away from the middle support plate.

When the first bearing plate and the second bearing plate are away from the end of the rotating shaft and facing away from the right connecting portion, the torsion spring is in a natural state.
[0014] The beneficial effect of the above scheme is that when the hook head is hooked with the middle abutment plate and the two cabinets are tightly fitted, the torsion spring is in a natural state. At this time, the torsion spring can prevent the middle abutment plate from rotating to limit the hook head from being unhooked therefrom.
[0015] In summary, the beneficial effects of this scheme are:
[0016] In the test stand locking structure provided by the utility model, the hook head on the extension arm cooperates with the left connecting part, and the hook head and the left connecting part are hooked tightly by adjusting the left connecting part, so as to drive the two cabinets to fit tightly. The test stand locking structure provided by the utility model has the effect of locking the two cabinets so that the two cabinets form a whole. BRIEF DESCRIPTION OF THE DRAWINGS
