Since the driving component 200 drives the connecting plate body 310 to drive the pressing rod body 320 to slide downward a predetermined distance in the vertical direction, so that the pressing portion 321 is used to abut against the workpiece 20, the pressing portion 321 is used to press and fix the position of the workpiece 20, so that the pressing portion 321 is used to clamp and fix the workpiece 20 to the device main body 100. Furthermore, it solves the problem in the prior art that the staff manually tightens the nut to clamp and fix the workpiece 20 to the supporting seat body, so that the workpiece fixture device 10 has a high degree of automation under the action of the driving component 200. The operation time of the driving component 200 driving the pressing portion 321 to clamp the workpiece 20 is shorter than that of the traditional method of the staff manually tightening the nut to clamp the workpiece 20, saving the clamping operation time of the workpiece fixture device 10 for the workpiece 20. Thus, it is easier for the workpiece fixture device 10 to quickly clamp the workpiece 20, and furthermore, the convenience of the workpiece fixture device 10 for quickly clamping the workpiece 20 is better.
