The invention belongs to the field of new energy vehicles, and particularly provides a locking and unlocking fixture capable of adaptive position adjustment. The invention aims to solve the problems of existing automated unlocking apparatuses for traction batteries having high requirements for machining precision, and the resulting machining difficulties. The locking and unlocking fixture of the invention comprises: a fixture sleeve, a base sheathed inside the fixture sleeve, and a first spring provided between the fixture sleeve and the base, wherein a clearance fit is formed between the fixture sleeve and the base, and the fixture sleeve can move vertically relative to the base, such that the fixture sleeve can match a locking device of the power battery even if there is a certain positioning error when the fixture sleeve is engaged with the locking device, and the fixture sleeve can return to an initial position under the action of the first spring when the fixture sleeve is disengaged from the locking device of the power battery. As a result, it is not necessary for the locking and unlocking fixture of the invention to provide high-precision machining and installation to enable an automated unlocking apparatus to successfully unlock the power battery.
