[0031] Embodiment 1:

[0032] Please refer to Figures 1-5, A clampable weighing platform of an electronic weighing scale, including an electronic weighing scale main body 1. A weighing platform body 2 is provided at the lower end of the electronic weighing scale main body 1. One end of the upper end of the weighing platform body 2 is fixed with a pressing plate 3. A second support 5 is fixed inside the weighing platform body 2 at the end far from the pressing plate 3. A bidirectional screw 11 and a limiting guide post 12 are respectively arranged inside the second support 5. The bidirectional screw 11 is rotationally connected with the second support 5, and the limiting guide post 12 is fixed with the second support 5. When a sphere or an unstable object to be weighed is placed on the upper end of the weighing platform body 2, in order to facilitate clamping and fixing it, so as to facilitate subsequent weighing, automatic clamping plates 14 are arranged on both sides of the upper end of the weighing platform body 2. Mounting slides 13 are threadedly connected to the outer sides of both sides of the bidirectional screw 11. The mounting slides 13 are slidably connected with the limiting guide post 12. A connecting frame 15 is fixed between each mounting slide 13 and the automatic clamping plate 14;

[0033] The inner side of the connecting frame 15 is attached to the weighing platform body 2. In order to facilitate driving the bidirectional screw 11 to rotate, and further facilitate driving the two mounting slides 13 to approach each other synchronously under the guidance of the limiting guide post 12, so that the two automatic clamping plates 14 can clamp the object to be weighed. A driving component is arranged between the bidirectional screw 11 and the second support 5;

[0034] Specifically, the driving component includes a reduction motor 17. The reduction motor 17 is also fixed inside the second support 5. The output end of the reduction motor 17 is fixed with a second flat gear 18. The center of the outer side of the bidirectional screw 11 is fixed with a first flat gear 16. The first flat gear 16 is meshed and connected with the second flat gear 18;

[0035] Embodiment 2:

[0036] The clampable weighing platform of the electronic weighing scale provided in Embodiment 1 is further optimized. Specifically, as Figure 3 shown, in order to cooperate with the pressing plate 3 to further limit and clamp the object to be weighed placed on the upper end of the weighing platform body 2 and improve its placement stability, a manual clamping plate 7 is also slidably connected inside the weighing platform body 2. The upper end of the manual clamping plate 7 extends to the upper end of the weighing platform body 2. A first support 4 is fixed at the center inside the weighing platform body 2. Limiting guide rods 6 are symmetrically and slidably connected inside the first support 4. One end of each of the two limiting guide rods 6 is fixed with the manual clamping plate 7. The other ends of the two limiting guide rods 6 are both fixed with springs 10. One end of each of the two springs 10 far from the limiting guide rods 6 is fixed with the weighing platform body 2;

[0037] When using the elastic characteristic of the spring 10 to pull the limit guide rod 6 to reset, thereby driving the manual clamping plate 7 to reset and move to cooperate with the pressure plate 3 to clamp the object to be weighed, in order to ensure that the friction force between the contact surface of the manual clamping plate 7 and the object to be weighed is sufficient to make the clamping more stable, an anti-slip pad 8 is fixed at the upper end of the manual clamping plate 7 and located at the upper end of the weighing table body 2. The anti-slip pad 8 corresponds to the pressure plate 3. In order to facilitate pulling the manual clamping plate 7 away from the weighing table body 2, so as to facilitate placing the object to be weighed on the upper end of the weighing table body 2, a handle 9 is fixed at the end of the manual clamping plate 7 away from the limit guide rod 6 and located outside the weighing table body 2;

[0038] The use process of the clampable electronic weighing scale platform provided by the present utility model is as follows: First, grasp the handle 9 and pull the manual clamping plate 7 away from the weighing table body 2 and the spring 10 is stretched, as Figure 1 shown to create space for placing the object to be weighed, and then it is convenient to place the object to be weighed on the upper end of the weighing table body 2. After placing, first start the reduction motor 17 to drive the second spur gear 18 to rotate. Through the meshing of the second spur gear 18 and the first spur gear 16, the bidirectional screw 11 is driven to rotate, and then the two carrier slides 13 are driven to approach each other under the guidance of the limit guide posts 12, so that the two automatic clamping plates 14 approach each other to achieve clamping;

[0039] At this time, release the handle 9 and use the elastic characteristic of the spring 10 to drive the manual clamping plate 7 to reset, and cooperate with the resistance of the pressure plate 3 to facilitate further clamping of the object to be weighed, so that the object to be weighed is placed more stably during the weighing process, effectively avoiding the phenomenon of rolling or tipping over, and there is no need to groove the surface of the weighing table body 2, ensuring the integrity of the upper end of the weighing table body 2 and facilitating the placement of the object to be weighed.
