Preferably, the driving shaft is provided with a power motor.
Preferably, a center shaft of the driven module is not connected with the power motor, and the center shaft is disposed inside the casing.
Preferably, the first guiding rack and the second guiding rack each have an I-shaped cross section; one side of each guiding rack meshing with the gear is provided with a rack surface, and the other side is a plane.
Preferably, the bottoms of both the first clamping jaw and the second clamping jaw are provided with jaw blocks, and reinforcing ribs are disposed at the joints between the clamping jaws and the guiding racks.
Preferably, one end of the driving shaft on the outer side of the casing is provided with a groove matching a positioning pin for use. Compared with the prior art, the present invention provides an automatic clamping device which has a simple structure and a good clamping effect, is high in accuracy, good in maneuverability, low in cost and convenient to maintain, and has extensive practicality and promotional value. Brief Description of Drawings FIG. 1 is a schematic view of a structure of the present invention: FIG. 2 is a left view of FIG. 1; and FIG. 3 is a vertical view of FIG. 1.
