[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-Figure 3 As shown, a polishing device for wooden ornaments is composed of a pressure sensing drive housing 1 and a handle barrel housing 2;

[0019] The handle barrel shell 2 is fixedly mounted on one side of the pressure sensing driving shell 1. A limited rotating sleeve 21 is rotatably mounted inside the pressure sensing driving shell 1 through a rotating sleeve bearing frame 20. A sleeve gear 19 is fixedly mounted on the outer side of the limited rotating sleeve 21. The sleeve gear 19 is meshedly connected with the motor gear 10.

[0020] A motor 9 is installed inside the pressure sensor driving shell 1, and a main driving shaft 11 is connected and installed on the motor 9. The motor gear 10 is sleeved and fixed on the main driving shaft 11, so that the gear linkage drives the rotation of the limit rotating sleeve 21;

[0021] A rotating column 3 is inserted into the limit rotating sleeve 21, and the rotating column 3 rotates together with the limit rotating sleeve 21. The bottom end of the rotating column 3 extends to the bottom of the pressure sensing driving shell 1 and is connected to the polishing installation plate 4, so that the wooden decorations can be polished by rotating.

[0022] A pressure sensor 14 is installed on the top of the inner side of the pressure sensing drive shell 1. The top of the rotating column 3 extends to the top of the limiting rotating sleeve 21 and is rotatably installed with a pressure plate 16 through the disc bearing 13. The pressure plate 16 is arranged directly below the pressure sensor 14 and is used to press the pressure sensor 14 when in use, so as to detect the polishing pressure during polishing for more precise control. A pressure display screen 6 is installed on the outer shell wall of the pressure sensing drive shell 1 to display the pressure during polishing.

[0023] like Figure 1-Figure 3 As shown, the utility model also discloses the following more optimized specific structures:

[0024] A limiting sliding hole is opened on the pressure plate 16, and a limiting column 15 is slidably inserted in the limiting sliding hole. The top end of the limiting column 15 is fixedly installed on the inner top shell wall of the pressure sensing driving shell 1, and the bottom end of the limiting column 15 extends to the bottom of the pressure plate 16 and is installed with a spring stopper 18. A top pressure spring 17 is installed on the limiting column 15 between the spring stopper 18 and the pressure plate 16, which presses the pressure plate 16 onto the pressure sensor 14.

[0025] The bottom of the polishing installation plate 4 is provided with an attachment layer 5, and the attachment layer 5 is used for installing sandpaper for polishing.

[0026] A limit strip ear 22 is installed on the rotating column 3, and an ear strip groove 23 is opened on the inner sleeve hole wall of the limit rotating sleeve 21. The limit strip ear 22 is inserted into the ear strip groove 23, so that the rotating column 3 can rotate synchronously with the limit rotating sleeve 21.
