Specifically, the rotating drive block 9 and the rotating stirring block 8 are in a matching state, but there is no fixed relationship between them. Instead, the copper nut 17 is driven to rotate by the rotation of the adjusting screw 16, thereby pushing the rotating stirring block 8 to move, and at the same time driving the movement of the inner disc 2 and the middle movable disc 10 connected to the rotating stirring block 8, so as to achieve the effect of adjusting the rotation angle;

[0035] The locking assembly includes a locking piece 11, one end of which is locked on the inner disk 2 by a connecting screw 19, and the other end of the locking piece 11 extends to the upper end of the outer disk 1 and is provided with an arc-shaped travel groove. When the locking piece 11 is fixed, the high head screw 18 is inserted into the travel groove from top to bottom to fix the locking piece 11 on the outer disk 1.

[0044] During actual processing, the semiconductor device with test is placed in the hole groove in the middle of the octagonal block. The outer disk can be fixed to the test platform or placed separately. The inner disk is a movable part that rotates with the outer disk as the reference. During operation, the high-head screw in the locking assembly can be removed first according to needs. At this time, one side of the inner disk and the middle movable disk is in a movable state, and the other side (that is, the position of the first notch) is driven to rotate the adjusting screw by rotating the screw handle. The rotation of the adjusting screw drives the rotating stirring block fixed to the inner disk to move. The moving position of the rotating stirring block corresponds to the rotation angle of the inner disk and the middle movable disk. The rotation direction of the screw handle is adjusted to adjust the rotation of the device on the octagonal block. After adjusting to the appropriate position, the high-head screw is inserted into the stroke groove from top to bottom to fix the locking plate to the outer disk, and the direction adjustment is completed.
