[0015] Referring to Figures 1 - 3 , a fixture for processing hard alloy workpieces, including a support frame 5. A clamping plate 1 is rotatably arranged at the top of the support frame 5. A clamping groove 16 penetrating the upper and lower parts of the clamping plate 1 is formed in the middle of the clamping plate 1. A driving ring 11 and a driving gear 12 are rotatably arranged in the clamping plate 1. The driving gear 12 meshes with the tooth pattern arranged on the outer side of the driving ring 11. A plurality of screw rods 13 are rotatably arranged in the clamping plate 1. A driven gear 14 is arranged on the screw rod 13. The driven gear 14 meshes with a circle of tooth patterns arranged on the top of the driving ring 11. A plurality of slotted openings 15 penetrating the upper and lower parts of the clamping plate 1 are formed in the clamping plate 1. A clamping part 2 is slidably arranged in the slotted opening 15. The clamping part 2 is penetrated by the screw rod 13 and is screwed with the screw rod 13.

[0016] The clamping part 2 is in a frame shape. One end of it is located on the slotted opening 15, and the other end is located in the clamping groove 16. A rotating motor 4 is installed on the support frame 5. The output end of the rotating motor 4 is connected to the outer side of one end of the clamping plate 1 through a rotating shaft.
