[0028] A placement groove 11 is provided in the suspension block 9 , and a motor 10 is arranged in the placement groove 11 . The output end of the motor 10 is fixedly connected to the screw rod 12 .

[0029] In a specific embodiment of the utility model, as a basic component, the support frame is firmly connected to one end of the placement table 1, providing a stable support platform for the entire fixing mechanism. A suspension block 9 is fixed at the lower end of the placement table 1, in which a motor 10 is built. The output end of the motor 10 is directly connected to the screw rod 12. The screw rod 12 drives the screw nut 14 to move along its thread direction through rotational motion, and then drives the clamping rod 5 to rotate through the engagement of the rack 8 and the gear 4 to clamp the workpiece on the upper end of the placement table 1.

[0030] For details, please refer to Figure 2 One end of the suspension block 9 is fixedly connected to the limiting rod 13, one end of the screw nut 14 is provided with a limiting groove, and the screw nut 14 is slidably connected to the outer surface of the limiting rod 13 through the limiting groove.

[0031] In this embodiment: a limit rod 13 is also fixed to one end of the suspension block 9, and a limit groove is provided at one end of the screw nut 14 for slidingly cooperating with the outer surface of the limit rod 13, so as to ensure that the moving range of the screw nut 14 is controllable and prevent damage caused by overload or misoperation.

[0032] For details, please refer to Figure 2 The lower end of the placement table 1 is fixedly connected to a plurality of supporting legs 2, and the adjacent ends of the plurality of supporting legs 2 are fixedly connected to a reinforcing rod 3. One end of the screw rod 12 is fixedly connected to an anti-slip plate 15, and the diameter of the anti-slip plate 15 is larger than the diameter of the screw rod 12.

Adjacent supporting legs 2 are further reinforced by reinforcing rods 3 to enhance the overall rigidity of the device. One end of the screw rod 12 is equipped with an anti-slip plate 15, the diameter of which is designed to be larger than the screw rod 12 itself to prevent the screw rod 12 from accidentally detaching during operation and increase the safety of use. The lower end of the clamping rod 5 is connected to a connecting rod 6, and is connected to the clamping plate 7 through the connecting rod 6. The clamping plate 7 is used to directly contact and fix the sheet metal material.

[0034] The working principle and use process of this utility model:

[0035] First, place the sheet metal material to be processed on the placement table 1, and the operator starts the motor 10. The output end of the motor 10 directly drives the screw 12 to rotate. As the screw 12 rotates, the screw nut 14 on the screw 12 moves linearly along the thread direction of the screw 12. Since the screw nut 14 is fixedly connected to the rack 8, the rack 8 also moves along the linear track. Then, the rotation of the gear 4 causes the rotating shaft in the support frame and the clamping rod 5 connected thereto to rotate. The clamping rod 5 drives the clamping plate 7 to move toward the sheet metal material through the connecting rod 6 until the clamping plate 7 is tightly attached to and fixes the sheet metal material.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
