[0033] Reference Figure 2 The transmission mechanism 2 includes two reducers 22, a transmission rod 23, a motor 20, a threaded rod 24, a movable plate 25, and a movable clamping plate 26.

[0034] Reference Figure 1-2 There are four idler frames 4, and the four idler frames 4 are evenly distributed at the upper end of the base frame 1. Two positioning frames 27 are fixed to the upper end of one of the idler frames 4 by bolts. The idler frames 4 are evenly distributed to ensure that the belt is evenly stressed and to ensure the accuracy of the calibration. The threaded rod 24 can be rotated and limited by the positioning frame 27 on the inner surface of the positioning frame 27.

[0035] Reference Figure 2 A mounting bracket 21 is fixedly provided on one side of the motor 20, and one side of the mounting bracket 21 is fixedly connected to one side of one of the reducers 22. The motor 20 can be fixed on one side of one of the reducers 22 through the mounting bracket 21.

[0036] Reference Figure 2 Two limiting frames 29 are fixedly installed at the upper end of the base frame 1. Each of the two limiting frames 29 has a limiting groove 28 on one side. The moving plate 25 can slide and be limited on the inner surface through the limiting groove 28 on the limiting frame 29.

[0037] Reference Figure 3 The synchronization mechanism 3 includes four synchronization plates 30, synchronization frames 31, synchronization wheels 32, rotating plates 35, rotating clamping plates 36, code rods 33, and synchronization rods 34.

[0040] Through the synchronization mechanism 3, the synchronization wheel 32 can rotate by rotating the card plate 36, and can be limited by the synchronization groove 37 in the synchronization frame 31. This allows the synchronization wheel 32 to drive the code bar 33 to rotate through the rotating plate 35, so that the bar code or chain code can be placed. Furthermore, through the synchronization rod 34, other code bars 33 can be driven to move synchronously, thereby achieving the purpose of effective synchronization of the belt scale synchronization bar code verification device.
