Embodiment two:
referring to fig. 1 to 8, in order to further facilitate the accurate engagement of the round hole terminal connection wire with respect to the lower die holder 201, on the basis of the first embodiment, the improvement of the connecting piece is: the connecting piece at this time comprises a telescopic connecting rod 602 fixedly connected with the air cylinder and a long rod 601 fixedly connected with the front seat 302 and the rear seat 301, the long rod 601 enables the front seat 302 and the rear seat 301 to form synchronous movement, and a base 604 (the position of the base 604 is matched with the position of the placement groove 303) which can penetrate through the front seat 302 in a sliding manner is fixedly arranged at the end part of the telescopic connecting rod 602 far away from the air cylinder. When the round hole terminal connection wire is placed on the front seat 302 and the rear seat 301, the front side round hole terminal and part of the length connection wire of the connection wire are located on the base 604, and when the base 604 slides back from the front side of the front seat 302, the round hole terminal connection wire is inserted into the front seat 302 and can be pushed to advance synchronously.
In order to prevent the round hole terminal connecting wire from being limited when the base 604 drives the round hole terminal connecting wire to move forward, a supporting rod 603 is fixedly arranged on the surface of the telescopic connecting rod 602, a U-shaped frame 605 positioned below the front seat 302 is fixedly arranged at the end part of the supporting rod 603 away from the telescopic connecting rod 602, the U-shaped frame 605 has a certain width and depth, and the width dimension (front-back direction) of the U-shaped frame 605 is larger than the width dimension of the front seat 302 in the front-back direction, so that after the base 604 drives the round hole terminal connecting wire to move forward, the inner front wall of the U-shaped frame 605 is contacted with the front surface of the front seat 302, and the front seat 302 is driven to move.
Meanwhile, the depth of the U-shaped frame 605 is such that the front seat 302 will not disengage from the U-shaped frame 605 when the horizontal section is not lowered and the semicircular section is lowered, i.e. the front seat 302 is driven to move back and forth synchronously by the movement of the U-shaped frame 605, i.e. the depth of the U-shaped frame 605 is greater than the length of the semicircular section in the up-down direction. And in the initial state, the inner rear wall of the U-shaped frame 605 is attached to the rear surface of the front seat 302. In this embodiment, the U-shaped frame 605 is disposed corresponding to the front seat 302, and may also correspond to the rear seat 301 in actual use.
