The transmission structure 7 can control the position of the reinforcement plates 8, so that the two reinforcement plates 8 reinforce the two ends of the weighing scale.
[0024] The transmission structure 7 includes a shell 11, at both ends of which rotatable screws 12 are installed. The screw 12 is rotatably connected to the inside of the groove 6. A driven bevel gear 13 is installed at one end of the screw 12 located inside the shell 11. A motor 15 is installed at one end of the shell 11. An active bevel gear 14 is installed at the output end of the motor 15. The motor 15 drives the active bevel gear 14 to rotate. The active bevel gear 14 is meshed and connected to the driven bevel gear 13, thereby driving the driven bevel gear 13 to rotate, and then driving the screw 12 to rotate. The lower end of the reinforcement plate 8 is threadedly connected to the screw 12. The size of the lower end of the reinforcement plate 8 matches the groove 6, so that the reinforcement plate 8 slides inside the groove 6, so that the two reinforcement plates 8 clamp the two ends of the load-bearing beam.
