Then the staff can start the second electric push rod 303 to extend the connecting block 305 to position and clamp the upper side of the part. When the connecting block 305 contacts the surface of the part, the clamping plate 307 will extend to both sides along the surface of the part, increasing the contact area with the part. At this time, the return spring 308 is stretched by force, which strengthens the clamping effect of the clamping plate 307. Positioning the upper and lower sides of the part respectively ensures the stability of the part during assembly and can ensure the positioning effect when the part changes in size. Two corresponding clamping plates 307 are set in the same connecting block 305.

[0024] According to another embodiment of the present invention, Figure 1 and Figure 2 As shown, the clamping plate 307 is set in an arc shape, and a cotton pad is provided on the surface of the clamping plate 307 to prevent the clamping plate 307 from causing unnecessary damage to the parts during positioning.
