The upper end of the bracket assembly is provided with an annular second support frame 11, and the outer end surfaces of the left and right ends of the second support frame 11 are rotatably connected with rotating blocks 12. The upper end surfaces of the two groups of rotating blocks 12 are provided with arc-shaped support rods 1201, and the upper ends of the two groups of support rods 1201 are provided with splints 1202. The outer peripheries of the two groups of support rods 1201 slide against the limiting ring 1203, and a third driving assembly is connected between the limiting ring 1203 and the second support frame 11. The clamping device 2 can also be hoisted to reduce dust accumulation. The clamping device 2 can also be placed in the processing device 3 to improve the integration. The feeding device 1, the clamping device 2, and the processing device 3 are all electrically connected to the CNC device.

[0028] The first driving component is the second electric telescopic rod 8. The lower end of the second electric telescopic rod 8 is rotatably connected to the lower end of the first bracket 4. The output shaft of the second electric telescopic rod 8 is rotatably connected to the lower end surface of the support plate 6, which plays a driving role and can push the support plate 6 to rotate along a set of rotating shafts 601 to adjust the angle of the support plate 6.

[0029] The locking assembly includes a first connecting rod 7, and elastic assemblies 701 are provided at the left and right ends of the first connecting rod 7. The output ends of the two groups of elastic assemblies 701 are provided with a card block 702. The two groups of card blocks 702 are respectively movably abutted against the outer end surfaces of the two groups of rotating shafts 601. The outer end surface of the first support frame 5 is provided with a first electric telescopic rod 704 connected to the first connecting rod 7. The elastic assembly 701 includes a telescopic rod 707. The outer periphery of the telescopic rod 707 is wrapped with a first spring 706.

When the first connecting rod 7 is in the middle, the two groups of card blocks 702 are respectively abutted against the two groups of rotating shafts 601, so that the support plate 6 remains horizontal. When the first electric telescopic rod 704 is started, the first connecting rod 7 moves. Due to the limited elastic extension distance of the elastic assembly 701, a group of card blocks 702 disengages from one group of rotating shafts 601. At this time, the second electric telescopic rod 8 can be started to drive the support plate 6 to rotate along the other group of rotating shafts 601.

[0030] A first sliding groove 502 is provided on the left and right end faces inside the first support frame 5, and a second connecting rod 703 extending to the inside of the first sliding groove 502 is provided on the outer end face of the first connecting rod 7. The block 702 is rotatably connected to the end face of one side of the rotating shaft 601, and the first roller 705 is in sliding contact with the outer end face of the rotating shaft 601, so that the movement of the first connecting rod 7 is more stable, and the first roller 705 can reduce the friction between the block 702 and the rotating shaft 601.

[0031] The second driving assembly is the third electric telescopic rod 10, the lower end of the third electric telescopic rod 10 is connected to the upper end surface of the support plate 6, and the output shaft of the third electric telescopic rod 10 is connected to the outer end surface of the bracket assembly, so that the bracket assembly can be driven to move along the through slot 602.

[0032] The bracket assembly includes a second bracket 9, which is provided with multiple groups. The second support frame 11 is connected to the second bracket 9. The outer end surface of the second bracket 9 is located on the upper and lower sides of the support plate 6 and is rotatably connected with two groups of second rollers 901 that are respectively in sliding contact with the upper and lower end surfaces of the support plate 6, so that the second bracket 9 is fixed on the support plate 6 and moves.

[0033] A push plate 902 is provided on the outer end surface of the second bracket 9 and is in sliding contact with the upper end surface of the support plate 6. It can push away dust on the support plate, making the sliding of the second roller 901 more stable.

[0034] The splint 1202 is rotatably connected to the support rod 1201, and a limiting protrusion is set between the outer end surface of the splint 1202 and the support rod 1201, so that the rotation angle between the splint 1202 and the support rod 1201 is less than 30 degrees, so that the splint 1202 can rotate slightly to improve adaptability.

[0035] Two groups of third rollers 1204 are rotatably connected to the outer end face of the limiting ring 1203, and the two groups of third rollers 1204 are respectively slidably connected to the outer end faces of the two groups of support rods 1201. Limiting rings are provided on the left and right end faces of the two groups of third rollers 1204, and the two groups of limiting rings are respectively slidably abutted against the left and right end faces of the support rods 1201. A second spring 1205 is connected between the two groups of support rods 1201 to reduce the friction between the limiting ring 1203 and the support rods 1201. The second spring 1205 can push the two groups of support rods 1201 to open outward in a natural state.

[0036] The third driving component is the fourth electric telescopic rod 13. The lower end of the fourth electric telescopic rod 13 is connected to the upper end surface of the second support frame 11. The output shaft of the fourth electric telescopic rod 13 is connected to the limit ring 1203, which can drive the limit ring 1203 to move to control the opening and closing size between the two groups of support rods 1201.

[0037] Working method: When working, the wooden handle raw material to be processed is conveyed through the feeding device, and the first electric telescopic rod 704 is started. The output shaft of the first electric telescopic rod 704 drives the first connecting rod 7 to move. Due to the limited elastic extension distance of the elastic component 701, a group of blocks 702 are separated from a group of rotating shafts 601. At this time, the second electric telescopic rod 8 can be started to drive the support plate 6 to rotate along another group of rotating shafts 601. After rotating to the required angle, the third electric telescopic rod 10 is started to adjust the height of the splint 1202, and then the fourth electric telescopic rod 13 is started to control the movement of the limit ring 1203, so as to control the opening and closing size between the two groups of support rods 1201 to clamp the raw material. Repeat the above steps to move the support plate 6 to a horizontal position and start the processing device 3 for processing. After the processing is completed, repeat the above steps again, and the processed finished product can be conveyed to the feeding device 1.
