[0009] Figure 2 This is a structural schematic diagram of the second state of this utility model. Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] Please see Figure 1 and Figure 2 As shown, this utility model provides an embodiment: a hydraulically controlled safety device for a double vise, including a double vise 1. The double vise 1 has hydraulically driven movable clamping plates 2 at both ends of its clamping groove. A clamping seat 3 is located in the center of the clamping groove. Limiting grooves 4 are formed at the upper ends of both the left and right ends of the front and rear surfaces of the clamping groove. A first limiting safety element 5 is provided on the movable clamping plate 2, cooperating with the limiting groove 4. A second limiting safety element 6, cooperating with the first limiting safety element 5, is provided on both the left and right sides of the clamping seat 3. A thermal infrared human body sensor 7 is embedded in the upper end of the inner side of the movable clamping plate 2. This allows the double vise 1 to clamp a workpiece after it has been clamped, and when the thermal infrared human body sensor 7 detects a user's hand entering, the first limiting safety element 5 and the second limiting safety element 6 engage to prevent the double vise 1 from continuing to clamp and move, thus preventing injury to the user.

[0012] Please continue reading. Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the first limiting safety component 5 includes a telescopic cylinder 51. The telescopic cylinder 51 is embedded in the middle of the inner side of the movable clamping plate 2. A limiting plate 52 is provided at the end of the telescopic rod of the telescopic cylinder 51, and the limiting plate 52 is embedded in the limiting groove 4. This allows the telescopic cylinder 51 to drive the limiting plate 52 to move left and right within the limiting groove 4.
