[0002] The application number 202320171898.3 provides an electric four-dimensional mechanism for vacuum use. The inclination angles of a flange plate and a third adjustment plate are adjusted in an electric control manner to compensate for the influence of external mechanical vibration on external equipment. The way that a first guide block slides in a first slide rail restricts the rotation of the lead screw in a first lead screw stepping motor, enabling it to perform stable linear reciprocating motion to realize the adjustment of the inclination angles of the third adjustment plate and the flange plate. A third limiting member and a fourth limiting member respectively limit the stroke of the lead screws in the first lead screw stepping motor and the second lead screw stepping motor, so that the third adjustment plate and the flange plate are adjusted within a specified range.
[0003] However, when adjusting the movement of the sample, this device can only drive the sample to move in a plane and is inconvenient for adjusting the height of the sample. For existing four-dimensional adjustable sample racks, when adjusting the height of the sample, a relatively large number of electrical devices are required to control the lifting of the sample, and the height cannot be manually adjusted. This not only increases the cost of the equipment but also makes it inconvenient for users to randomly control the lifting of the sample, resulting in poor practicability.
