[0022] It should be noted that, by setting the active conveying platform 1 and the driven conveying platform 9, the active conveying platform 1 and the driven conveying platform 9 are matched and arranged to realize the conveyance of goods of different sizes. By rotating and connecting the roller components 3 that are equidistantly distributed on the active conveying platform 1 and the driven conveying platform 9, the roller components 3 are composed of an active roller 301 and a driven roller 304. In actual use, the active roller 301 and the driven roller 304 are used to realize the transmission of goods. By setting a connecting cylinder 302 at the opposite end of the active roller 301 and the driven roller 304, a round rod 307 is set on the inner side of the connecting cylinder 302. The round rod 307 extends into the active roller 301 and the driven roller 304, so that after the driven roller 304 moves a certain distance, the round rod 307 is still located in the active roller 301 and the driven roller 304. The round rod 307 can limit the connecting cylinder 302 through the relationship between the groove 308 and the protrusion 303. When the active roller 301 rotates, the driven roller 304 can rotate synchronously to achieve stable transportation of goods. This method can make the active roller 301 and the driven roller 304 rotate synchronously after the driven roller 304 moves telescopically, and the use effect is good.

[0029] like Figure 1 and Figure 3 As shown, in some embodiments, it also includes a track plate 8 located below the driven conveyor platform 9, and multiple track plates 8 are provided and reinforcement plates 5 are welded between the track plates 8. The track plate 8 includes a main body 801, and a T-shaped track groove 804 opened on the main body 801 along the length direction of the main body 801. A support frame 7 is fixed to the bottom of the driven conveyor platform 9, and a T-shaped slider 6 fixed on the lower surface of the support frame 7 is slidably connected to the T-shaped track groove 804. A screw hole penetrating to the T-shaped track groove 804 is opened on one side of the main body 801, and a locking screw 803 is provided at the screw hole, and a handle 802 is fixed to the end of the locking screw 803.

[0030] It should be noted that, by setting a track plate 8 and setting a support frame 7 at the bottom of the driven conveyor platform 9, the T-shaped slider 6 fixed on the lower surface of the support frame 7 is slidably connected to the T-shaped track groove 804, so that the driven conveyor platform 9 can be moved and the width between the active conveyor platform 1 and the driven conveyor platform 9 can be adjusted. By setting a locking screw 803 at the screw hole of the main body 801, the locking screw 803 can realize the positioning and fixation of the T-shaped slider 6 to ensure the stable use of the driven conveyor platform 9. The setting of the handle 802 facilitates the rotation operation of the locking screw 803.
