[0040] As shown in the drawings, Figures 3 to 10 The support assembly 220 includes a first support rod 221 and a second support rod 222. The second support rod 222 is fixed with a connecting shaft 223, and the connecting shaft 223 is inserted into the first support rod 221. The first support rod 221 and the second support rod 222 serve as supports. A spring 224 is installed between the first support rod 221 and the second support rod 222. The spring 224 is arranged between the first support rod 221 and the second support rod 222 to achieve elastic support of the support assembly 220 to the main frame 201. The sliding block 216 is fixed with a second connecting rod 217. The sliding block 216 drives the rotating disc 218 to move through the second connecting rod 217. The rotating disc 218 is rotatably arranged on the second connecting rod 217. The rotating disc 218 is used to push the tubular hardware fitting to move along the sliding track of the sliding block 216 on the slide rail 215.

The sliding block 216 is installed with a handle 225. The handle 225 is used to push the sliding block 216 to move.

[0041] Working principle: First, the transmission shaft 102 needs to be driven to rotate by the external driving device away from the polishing wheel 103 before use. When the tubular hardware fitting needs to be polished, the transmission shaft 102 is driven to rotate by the external driving device. The transmission shaft 102 drives the polishing wheel 103 to rotate. Then, the second roller 213 away from the base 1 is pressed down, so that the main frame 201 rotates and moves away from the polishing wheel 103. In the process of rotating the main frame 201, the first rotating shaft 203 is driven to rotate. The first rotating shaft 203 drives the first gear 205 to rotate on the sector gear 202, and the sector gear 202 drives the second rotating shaft 204 to rotate. The second rotating shaft 204 drives the third gear 211 to rotate. The third gear 211 drives the straight toothed plate 210 to move forward and backward. The straight toothed plate 210 drives the slide rod 209 to move forward and backward. The first roller 208 and the second roller 213 are slidably provided with a plurality of rolling balls 214. The rolling balls 214 are used to assist the tubular hardware fitting to move along the track of the slide rail 215 in the clamped state of the first roller 208 and the second roller 213. Figure 1As shown, the first gear 205 rotates counterclockwise, the first gear 205 drives the second gear 206 to rotate clockwise, the second gear 206 drives the third gear 211 to rotate clockwise through the second rotating shaft 204, the third gear 211 drives the straight toothed plate 210 to move towards the first connecting rod 212 when rotating clockwise, the straight toothed plate 210 drives the first connecting rod 212 to move through the sliding rod 209, and the first connecting rod 212 drives the second roller 213 to move away from the first roller 208;

[0042] Then, the tubular hardware fitting to be polished is placed between the pair of first rollers 208, and the horizontal rod 219 is compressed by pressing the first supporting rod 221 to compress the connecting shaft 223 towards the second supporting rod 222 during the process of pressing down the main frame 201. After the tubular hardware fitting to be polished is placed between the pair of first rollers 208, the main frame 201 is released, and the rebounding force of the connecting shaft 223 drives the first supporting rod 221 to move upwards when the main frame 201 is not pressed by external force. The first supporting rod 221 drives the main frame 201 through the horizontal rod 219 to rotate in a direction, and the main frame 201 drives the first rotating shaft 203 to rotate. The first rotating shaft 203 drives the first gear 205 to rotate on the sector gear 202 as shown Figure 1 As shown, the first gear 205 rotates clockwise, the first gear 205 drives the second gear 206 to rotate counterclockwise, the second gear 206 drives the third gear 211 to rotate counterclockwise through the second rotating shaft 204, the third gear 211 drives the straight toothed plate 210 to move towards the base 1 when rotating counterclockwise, the straight toothed plate 210 drives the first connecting rod 212 to move through the sliding rod 209, and the first connecting rod 212 drives the second roller 213 to clamp the first roller 208, so as to clamp the tubular hardware fitting between the second roller 213 and the pair of first rollers 208.

[0043] Then, when the tubular hardware fitting is close to the polishing wheel 103, the polishing wheel 103 polishes the tubular hardware fitting and drives the tubular hardware fitting to rotate between the second roller 213 and the pair of first rollers 208. Then, the handle 225 drives the sliding block 216 to move towards the main frame 201, the sliding block 216 drives the rotating disc 218 to move through the second connecting rod 217, the rotating disc 218 abuts against the tail end of the tubular hardware fitting and drives the tubular hardware fitting to move. The sliding block 216 is slowly pushed to make the polishing wheel 103 polish the tubular hardware fitting. After polishing, the tubular hardware fitting is taken out after the main frame 201 is pressed down again, and other tubular hardware fittings to be polished can be polished.
