The clamping channel 22 and the through hole 11 are coaxially arranged, so that concentricity of the insert pin 30 clamped between the body 10 and the clamping part 20 is improved, and the influence on machining accuracy caused by offset of the axis of the insert pin 30 relative to the clamping part 20 or the body 10 when the three-jaw clamp 40 clamps the outer sides of the clamping part 20 and the body 10 is avoided.

Before clamping the insert pin 30, the side surface of the body 10 away from the through hole 11 and the side surface of the clamping part 20 away from the clamping channel 22 are located on the same cylindrical surface, the clamping channel 22 and the through hole 11 are coaxially arranged, after clamping the insert pin 30, the three-jaw clamp 40 applies force to the clamping parts 20, and the clamping parts 20 are mutually close to each other. The boss of the insert pin 30 away from the processing material level can be abutted against one side of the body 10 away from the clamping part 20.

The diameter of the through hole 11 may be appropriately designed according to the diameter of the actual insert 30, for example, when the insert 30 with a diameter of 3.5mm is clamped, the through hole 11 is correspondingly set to 3.51mm, so that the insert 30 can pass through the through hole 11, and the insert 30 and the through hole 11 can be kept stable and free from shaking. A marking portion 25 may be provided on the outer side of the clamping portion 20 or the body 10, and the marking portion 25 is used to correspondingly mark the diameter of the insert pin 30 that can be clamped.

In some alternative embodiments, the waste recovery holes 23 extend in the radial direction of the clamping channel 22, thereby facilitating the removal of waste.

In order to increase the guiding out of the waste material, avoiding that dust and debris cannot fall out due to rotation of the body 10 and the clamping parts 20, in some alternative embodiments, waste material recycling holes 23 are provided on at least two clamping parts 20 or in at least two avoidance gaps 21, the waste material recycling holes 23 being arranged around the clamping channel 22.
