[0030] The specific usage and function of this embodiment are as follows:
[0031] In this utility model, such as Figure 1As shown, the adjustable jaw plate 3 and the movable jaw plate 7 hold the aircraft parts to be drilled. Shims are placed on the inner end faces of the adjustable jaw plate 3 and the movable jaw plate 7, thus supporting the aircraft parts. The right end face of the aircraft parts contacts the left end face of the adjustable positioning plate 11, thereby positioning the right end of the aircraft parts using the adjustable positioning plate 11. This ensures the right end of the aircraft parts is always in the same position, facilitating batch drilling operations without requiring positioning each time. When the position of the adjustable jaw plate 3 is adjusted, the jaw plate locking rod 4 is rotated using a tool to engage with the threads of the fixed support plate 2 and the adjustable jaw plate 3. This causes the jaw plate locking rod 4 to rise through the thread engagement, disengaging its lower end from the threaded blind hole of the fixed support plate 2, thereby allowing the aircraft parts to be drilled. The jaw locking rod 4 releases the adjustable jaw plate 3 from its fixation, allowing the adjustable jaw plate 3 to move forward or backward. Then, by rotating the jaw locking rod 4 with a tool, it engages with the threaded engagement of the adjustable jaw plate 3, causing the jaw locking rod 4 to descend through the threaded engagement. The lower end of the jaw locking rod 4 is then screwed into the threaded blind hole of the fixed bearing plate 2, thus achieving the rearward fixation of the adjustable jaw plate 3. When the position of the adjustable positioning plate 11 is being adjusted, the positioning adjusting cylinder 10 is rotated with a tool to engage with the threaded engagement of the positioning bearing rod 8, causing the positioning adjusting cylinder 10 to move left or right through the threaded engagement. This causes the positioning adjusting cylinder 10 to drive the adjustable positioning plate 11 to move left or right synchronously through the bearing, thus achieving the position adjustment of the adjustable positioning plate 11. At the same time, the self-locking property of the threads of the positioning bearing rod 8 and the positioning adjusting cylinder 10 achieves self-locking and stopping.
[0032] Example 2:
[0033] The difference from Embodiment 1 is that the regular hexagonal groove of the limiting anti-detachment column 9 can also be set as a regular heptagonal groove, so that the limiting anti-detachment column 9 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the limiting anti-detachment column 9.
[0034] Example 3:
[0035] The difference from Embodiment 1 is that the regular hexagonal prism of the fixed anti-rotation post 12 can also be set as a regular heptagonal prism, so that the fixed anti-rotation post 12 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed anti-rotation post 12.
