The gear 4 is provided between the first rack 2 and the second rack 3 and is engaged with both the first rack 2 and the second rack 3.
The working principle of this embodiment is as follows:
the motor body drives the screw rod 1a to move back and forth along the length direction, the screw rod 1a drives the first clamping jaw 5 to move, the first clamping jaw 5 drives the first rack 2 to move along the length direction, and the second rack 3 moves in the opposite direction to the first rack 2 under the action of the gear 4, so that the jaw clamp is opened and closed.
The embodiment is also provided with a seat 7, and the motor is connected to the seat 7. The seat 7 is provided with a chute, the first rack 2 is arranged on the chute, the back surface of the first rack 2 is contacted with the bottom surface of the chute, the back surface of the first rack 2 is the surface of the first rack 2 opposite to the tooth surface, and the first rack 2 can slide back and forth on the chute. The design of the seat 7 allows all the parts of the jaw to be integrated in the seat 7, thus forming an independent jaw, which is modular.
In this embodiment, a slot 5c is also provided in the middle of the first jaw 5. The second rack 3 is disposed on the slot 5c and can slide back and forth on the slot 5c, and since the tooth surfaces of the first rack 2 and the second rack 3 are opposite, the opening directions of the chute and the slot 5c should be opposite. In the process of opening and closing the tiger mouth clamp, the first rack 2 is not separated from the chute, and the second rack 3 is not separated from the slotted hole 5c.
The design of the sliding groove and the slot 5c can ensure the stability of the first rack 2 and the second rack 3 in the dislocation sliding process, so that the shapes of the sliding groove and the slot 5c respectively correspond to the first rack 2 and the second rack 3, namely, the back surface and the two side surfaces of the first rack 2 are limited on the bottom surface and the two side surfaces of the sliding groove, and the back surface and the two side surfaces of the second rack 3 are limited on the bottom surface and the two side surfaces of the slot 5c.
