Through set up first sliding seat 2 on fixing base 1, utilize first translation actuating mechanism 4 drive first sliding seat 2 to slide relative fixing base 1, thereby make push-pull mechanism 100 is last to have first order stroke, be in again set up second sliding seat 3 on first sliding seat 2, and utilize second translation actuating mechanism 5 drive second sliding seat 3 slides relative first sliding seat 2, makes the slip direction of first sliding seat 2 and second sliding seat 3 the same, thereby make push-pull mechanism 100 have second order stroke, through first order stroke and second order stroke overlap, make push-pull mechanism 100's stroke has increased one time than original, consequently, the stroke obtains very big improvement. In addition, by using the engaging mechanism 6, when the push-pull mechanism 100 approaches the battery holder 600, the engaging mechanism 6 can be inserted into the battery holder 600, thereby driving the battery holder 600 to enter and exit the oven through the engagement connection, so that the situation of disengaging from the battery holder 600 does not occur, and the reliability is extremely high.
