The first elastic piece 8 is a pressure spring, when the tool bit is pressed in the vertical direction, the pressure spring slowly deforms, the tool bit sinks, when the deformation reaches a certain degree, the pressure spring does not deform and supports the tool bit, and after the pressure is relieved, the tool bit resets upwards, floats upwards until the tool rest seat 31 abuts against the limiting structure; when the tool bit is subjected to an acting force deflected leftwards, the tool holder seat 31 presses the left side of the pressure spring downwards, the tool bit inclines leftwards, the pressure spring returns after the external acting force is removed, and the tool bit also returns to a normal state; when the tool bit receives acting force deflected rightwards, the tool rest seat 31 presses the right side of the pressure spring downwards, after the external acting force is relieved, the pressure spring returns, and the tool bit also returns to a normal state.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
