The worker can continuously control the movement of the movable block 15 until the original element at the end of the sampling claw 20 is aligned with the entrance of the crimping box 7. The two limiting rings 17 and the limiting block 13 limit the screw rod 14, the worker can place the rubber buffer block 22 between the support table 8 and the fixed table 10 to buffer stress and reduce shaking. During the process, whenever the worker controls the hydraulic cylinder 5 to press the two first clamping blocks 25 tightly on the second clamping block 18, the jig structure will produce slight shaking, and the multiple rubber buffer blocks 22 between the support table 8 and the fixed table 10 can effectively absorb the shaking, thereby keeping the support table 8 stable. Whenever terminal crimping work of different sizes is needed, the worker can remove the multiple screws 9 between the mounting block 24 and the crimping box 7, thereby contacting the connection relationship between the second clamping block 18 and the crimping box 7, so as to replace different second clamping blocks 18 for crimping terminals of corresponding sizes.
