[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a wall plaster removal device, including a holding cylinder 1. An adjustment structure is provided on the inner side of the holding cylinder 1. The adjustment structure includes two threaded rods 4, which are rotatably installed on the inner side of the holding cylinder 1. A second gear 3 is fixedly installed on the outer side of each of the two threaded rods 4 near one end. A first gear 2 is meshed between the two second gears 3. The first gear 2 is rotatably installed on the inner side of the holding cylinder 1. A movable circular plate 5 is threadedly connected to the outer side of the two threaded rods 4. The movable circular plate 5 is located on the inner side of the holding cylinder 1 and slides in contact with the holding cylinder 1.

[0021] A rotating shaft 7 is fixedly installed on the top of gear 2. The rotating shaft 7 passes through the top of the gripping cylinder 1 and is rotatably connected to the gripping cylinder 1. A worm gear 8 is fixedly installed on the top of the rotating shaft 7.

[0022] The outer side of the worm gear 8 is meshed with a worm 10. Both ends of the worm 10 are rotatably mounted with fixed seats 9. Both fixed seats 9 are fixedly installed on the top of the holding cylinder 1. A turntable 11 is fixedly installed on one end of the worm 10.
