[0034] By providing an inner and outer clamping assembly, before the clamping plate 204 fixes the cargo in the elevator car 1, by rotating the rotating shaft 302, the positive thread 304 and the reverse thread 305 on the rotating shaft 302 drive the two clamping blocks 306 to move in opposite directions, and the two clamping blocks 306 are located at both ends of the slide groove 301, and then the motor 205 is rotated to make the clamping plate 204 clamp the left and right sides of the cargo. At this time, the two clamping plates 204 are respectively located on the inner and outer sides of the cargo, and then the rotating shaft 302 is reversed, and the positive thread 304 and the reverse thread 305 on the rotating shaft 302 drive the two clamping blocks 306 to move in opposite directions, so that the two clamping blocks 306 clamp the inner and outer sides of the cargo, which can not only clamp the left and right sides of the cargo, but also clamp the inner and outer sides of the cargo, thereby further ensuring the stability of the cargo.
[0035] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
