[0023] The four corners of the bottom of the platform 1 are respectively fixedly connected with support legs 22, and the bottom of the support legs 22 is provided with a friction layer. The support legs 22 use the friction layer to make the platform 1 have good stability and prevent the platform 1 from generating large vibrations when in use;

[0024] The two sides above the platform 1 are respectively fixedly connected with connecting blocks 2, and the first bearings 3 are respectively clamped in the two connecting blocks 2. The same threaded rod 4 is rotatably connected in the two first bearings 3. The threads on both sides of the threaded rod 4 are arranged oppositely. One end of the threaded rod 4 is fixedly connected with a motor 5. The output shaft of the motor 5 is fixedly connected to one end of the threaded rod 4, so that when the motor 5 is running, the output shaft can be used to drive the threaded rod 4 to rotate, so that the threaded block 6 that matches the thread of the threaded rod 4 can move smoothly.

[0025] The motor 5 is fixedly connected to a motor fixing block 18, one side of the motor fixing block 18 is fixedly connected to one side of the platform 1, and the motor fixing block 18 provides a fixing point for the motor 5, thereby reducing the adverse effects caused by shaking and displacement when the motor 5 is running, thereby effectively improving the stability of the motor 5 when running;

[0026] The threaded rod 4 is externally threadedly connected to two threaded blocks 6, and positioning plates 7 are fixedly connected to the tops of the two threaded blocks 6, so that when the threaded rod 4 rotates, the two threaded blocks 6 that are threadedly matched with the threaded rod 4 can respectively drive the positioning plates 7 to move closer to each other, so that the two positioning plates 7 can fix the metal on the placement block 21;

[0027] Four slide bars 8 are slidably connected in the two positioning plates 7, respectively, wherein the other ends of the two slide bars 8 are fixedly connected to the same positioning block 9, and a spring 10 is connected to the outer sleeve of the slide bar 8, one end of the spring 10 is fixedly connected to one side of the positioning plate 7, and the other end of the spring 10 is fixedly connected to one side of the positioning block 9, so that the slide bar 8 cooperates with the spring 10 to make the positioning block 9 have elastic adjustment force, and the elastic force provided by the spring 10 makes the positioning block 9 have the function of elastic reset;

[0028] A force block 11 is fixedly connected to one side of the positioning block 9, two second bearings 12 are respectively clamped in the two positioning plates 7, and a rotating shaft 13 is rotatably connected in the two second bearings 12, and a hand 16 is fixedly connected to one end of the rotating shaft 13. A limiting block 17 is fixedly connected to the bottom of the threaded block 6, and the hand 16 makes one of the rotating shafts 13 have a rotating point, which is convenient for the staff to rotate one of the rotating shafts 13, so that one of the rotating shafts 13 can drive one of the gears 14 to rotate smoothly, and the movement of the limiting block 17 in the slide groove 19 can ensure the stability of the threaded block 6 when moving;

[0029] Gears 14 are fixedly connected to the outside of the two rotating shafts 13, and the two gears 14 are meshed. The other ends of the two rotating shafts 13 are fixedly connected to extrusion blocks 15, so that when one of the gears 14 rotates, the other gear 14 meshed with it can drive the other rotating shaft 13 to reverse, so that the two rotating shafts 13 can respectively drive the extrusion blocks 15 to reverse and squeeze the two force blocks 11, so that the two force blocks 11 can respectively drive the positioning blocks 9 to move away from each other by utilizing the cooperation between the slide rod 8 and the spring 10, so as to increase the contact area of ​​the positioning plate 7.

[0030] The working principle of the utility model is:

[0031] When the metal needs to be fixed, the metal is first placed on the placement block 21, and then the motor 5 is started, so that when the motor 5 is running, the output shaft can be used to drive the threaded rod 4 to rotate, so that when the threaded rod 4 rotates, the two threaded blocks 6 threadedly connected thereto can use the opposite threads on both sides of the threaded rod 4 to achieve the work of approaching each other, so that the two threaded blocks 6 respectively drive the positioning plates 7 to approach each other, so that when the two positioning plates 7 approach each other to a certain position, the metal on the placement block 21 can be fixed;

[0032] When the area of ​​the metal object is large, the two handles 16 can be rotated separately, so that the handles 16 drive one of the rotating shafts 13 to rotate, so that one of the rotating shafts 13 drives one of the gears 14 to rotate, so that when one of the gears 14 rotates, the other gear 14 meshing with it can drive the other rotating shaft 13 to rotate in the opposite direction, so that the two rotating shafts 13 respectively drive the extrusion blocks 15 to rotate in the opposite direction, so that the two extrusion blocks 15 can respectively extrude the force-bearing blocks 11, so that the two force-bearing blocks 11 can respectively drive the positioning blocks 9 to utilize the cooperation between the slide rod 8 and the spring 10 to achieve the work of moving away from each other, so that the two positioning blocks 9 cooperate with the positioning plate 7 to expand the contact area.
