[0034] Working principle: When in use, the staff places the mechanical parts that need to be repaired in the inner cavity of the limit frame 7, and then rotates the twist block 811. When the twist block 811 disengages from the bolt 810 to release the limit on the limit plate 804, the second positioning plate 806 is pulled upward. When the second positioning plate 806 moves upward, it drives the fixed rod 805 and the limit plate 804 to move upward.
