A jaw pressing block 313 is arranged between the first clamping teeth 311 and the second clamping teeth 312, and the jaw pressing block 313 is used to press the key clamped by the jaws 31. The jaws 31 are distributed linearly. The first clamping teeth 311 of the linearly distributed jaws 31 are connected to the same first clamping jaw connecting plate 32. The second clamping teeth 312 of the linearly distributed jaws 31 are connected to the same second clamping jaw connecting plate 33. The first clamping jaw connecting plate 32 is connected to a first driving device 34, and the second clamping jaw connecting plate 33 is connected to a second driving device 35. The first driving device 34 and the second driving device 35 make the corresponding first clamping jaw connecting plate 32 and the second clamping jaw connecting plate 33 move in opposite directions, thereby driving the first clamping teeth 311 and the second clamping teeth 312 of each group of clamping jaws 31 to move in opposite directions, so as to clamp the teeth of the key handle. At the same time, the clamping jaw pressing block 313 arranged between the first clamping teeth 311 and the second clamping teeth 312 presses the key from above the key, further improving the clamping stability.

And the material clamping notch 422 is perpendicular to the single-row material troughs 421. A vibration plate is also provided on both sides of the product distributing platform 42. The working principle of the vibration plate is: the key handle is continuously vibrated by utilizing the different weights at both ends of the key handle, so that the key handles finally discharged from the vibration plate are all in the same direction, completing the distributing process of the vibration plate 41 part. Both vibration plates 41 are connected to a feeding track 43, and the two feeding tracks 43 are respectively connected to the material troughs 421 on the sides of the product distributing platform 42, and ensure that the material troughs 421 connected by the two feeding tracks 43 are on the same straight line. Feed limit devices 44 are provided at the sides of the product distributing platform 42 near the two feed tracks 43. The feed limit devices 44 prevent the key handle from rushing into the feed track 43 and sliding into the material trough 421 when resetting the product distributing platform 42, thereby affecting the subsequent distributing.
