The invention provides a novel scanning tunneling microscope design structure using a motor-scanning head separation technique. A motor and a scanning head are separated, the scanning head is clamped at a guide rail independently by a spring piece, and the motor is responsible for pushing the scanning head to a tunnel current zone; and then the scanning head retreats autonomously. The scanning head is composed of a probe, a probe rack, a scanning tube, a corundum pedestal, and a corundum pipe and the like. Therefore, influences on imaging of the scanning head by interference factors like thermal drift and electric fluctuating caused by the motor can be prevented and thus imaging becomes clear.

The invention discloses a method for in-situ dynamic three-dimensional reconstruction of a sample by using a multi-degree-of-freedom sample rod. The method comprises steps of manufacturing the samplerod, and loading a sample into a head end of the sample rod; inserting the sample rod into a transmission electron microscope to adjust a feature point on a to-be-observed area of the sample to be aligned with the axis of the sample rod; enabling the rotating shaft to accumulatively rotate by 180 degrees, and taking a picture every other 1 degree; and S3, importing the pictures obtained in the step S3 into a computer, and carrying out three-dimensional reconstruction.

The invention discloses a multi-degree-of-freedom sample rod with a sample clamping nozzle, and the rod comprises a sleeve, a pre-tightening screw and a detachable sample clamping nozzle; the sample clamping nozzle comprises a clamping part for loading a sample and a connecting part. Samples of various sizes can be observed, the sample clamping nozzle is arranged to be used for installing the samples, the samples and the sample clamping nozzle can serve as sample assemblies to be installed at the front end of the sample rod, thereby facilitating installation and disassembly.

The invention provides a drawer type mobile terminal virtual reality head-mounted display. The head-mounted display comprises a containing device and a containing cavity. The containing device can beused for containing a mobile terminal. The containing device can be placed in the containing cavity. The containing device is provided with a positioning ruler and a clamp. Compared with the prior art, the positioning ruler is arranged on the containing device, so that the position of the mobile terminal can be effectively adjusted. As a result, the mobile terminal is prevented from being locatedtoo far to the left or to the right to influence the imaging and displaying effect. The shape of the containing device is set to be a drawer, so that the containing device can be taken out or placed inside conveniently. Meanwhile, the mobile terminal is convenient to place. A marker is further arranged, so that the position of the common mobile terminal can be more clearly and conveniently set. The convenience is provided.

The invention relates to a radiographic inspection positioning device for large-curvature hollow blades, belonging to the technical field of radiographic inspection. The device comprises a support, two positioning blocks and a limiting pin, wherein the clamping ends of the positioning blocks are symmetrically arranged on the support; the support comprises two profiles of different angles; the limiting pin is arranged at one end, between the two positioning blocks, at the included angle end of the profiles of the support; and the clamping end faces of the two positioning blocks are connected with blade tenons in a matched mode. According to the device disclosed by the invention, the radiographic inspection angles of the blades can be accurately and rapidly positioned, a phenomenon that negative film imaging is influenced because the inner cavity structures of the blades block one another is avoided, an image contrast ratio is enhanced, and the detection quality is guaranteed. The inspection of residual cores of inner cavities of the large-curvature hollow blades is needed by technological development, and immeasurable social benefits are brought.

The invention discloses a multi-degree-of-freedom sample rod with an optical fiber, which comprises a framework. An optical fiber groove is formed in the framework. The side surface of the framework is provided with the optical fiber groove for the optical fiber to pass through, thereby avoiding abrasion and winding of the optical fiber and being beautiful in wiring; moreover, the optical fiber groove is connected with a front-end circuit board, the front-end circuit board has the function of guiding the optical fiber, the head of the optical fiber passes through the front-end circuit board, the head of the optical fiber has small bending amplitude, and light waves cannot be attenuated.

The invention discloses a multi-degree-of-freedom sample rod with a rotating shaft driving assembly. The sample rod comprises a shell and a rotating shaft, wherein at least one group of rotating shaftdriving assembly is arranged between the shell and the rotating shaft, each group of rotating shaft driving assembly comprises two driving units which are symmetrically arranged, and each driving unit comprises a substrate, an electrode and a piezoelectric ceramic piece. The sample rod is advantaged in that by arranging a plurality of groups of rotating shaft driving assemblies, the rotating shaft can rotate and axially move, and multi-degree-of-freedom driving of the sample rod is realized.

The invention discloses an adjusting method for aligning a sample to the axis of a rotating shaft. The adjusting method comprises steps of manufacturing a sample clamping nozzle, inserting a sample rod with the sample into a transmission electron microscope and the like. When the rotating shaft rotates, a to-be-observed area of the sample is always in the observation visual field of the transmission electron microscope by adjusting the sample to align with the axis of the rotating shaft.

The invention discloses a multi-degree-of-freedom sample rod, and the sample rod comprises a shell and a rotating shaft; a skeleton is arranged between the shell and the rotating shaft, and the skeleton is coaxial with the shell and the rotating shaft. During assembly, the rotating shaft and the skeleton are coaxial, then the rotating shaft-skeleton is installed in the shell, and the rotating shaft, the skeleton and the shell are coaxial, so the installation precision is improved; in addition, the skeleton further provides an installation position for the rotating shaft driving assembly, and the skeleton further plays a role in separating the rotating shaft from the wire and preventing the wire from interfering with rotating shaft movement.

The invention belongs to the field of robots, and particularly relates to an unattended oil field transfer station robot based on an image recognition system. According to an existing unattended oil field transfer station robot, a camera is inconvenient to clean in the use process, dust is accumulated after long-time use, and the definition of the camera is reduced; and in the use process, the camera is inconvenient to shade, so that the strong light is easy to influence the imaging of the camera. In order to solve said problems, the following scheme is provided: the robot comprises a robot body; a storage box is fixedly mounted at the top of the robot body through bolts, and a first mounting groove is formed in the storage box. According to the invention, the camera can be cleaned conveniently in the use process, so that the definition of the camera can be prevented from being reduced by dust; the camera can be conveniently shaded in the use process, so that the influence of strong light on imaging of the camera is avoided; the structure is simple and use is convenient.
