The number of the mounting portions 11 may be one, or two or more, and specifically, the number may be 1, 2, 3 … … N, or N +1, where N is a positive integer greater than 0.
The cushion member 20 is mounted between the mounting portion 11 and the machine body 200, the cushion member 20 may be mounted on the machine body 200 in many ways, specifically, the cushion member 20 may be clamped on the machine body 200, may be screwed with the machine body 200, or may be directly bonded to the machine body 200, which is not limited to this, and it is understood that the cushion member 20 may be mounted on the mounting portion 11 in the same way.
The cushion member 20 may position the mounting portion 11, and the cushion member 20 may specifically position the mounting portion 11 by applying clamping force to the mounting portion 11 in two parts, or may position the mounting portion 11 only by tight engagement with the mounting portion 11, which is not specifically limited herein.
The cushion member 20 is also used to cushion the vibration generated by the mounting portion 11, and the cushion member 20 may be formed of an elastic material as a whole or may be formed of a hard material and an elastic material as a part. The cushion member 20 is in contact with the mounting portion 11 by a portion having elasticity, thereby playing a role of absorbing the shock generated from the mounting portion 11 or absorbing the shock generated from the device body 200.
