The invention discloses an entertainment multi-angle photograph platform for a tourist attraction. The entertainment multi-angle photograph platform for the tourist attraction comprises a bearing ringand a camera assembly. A ring-shaped guide groove is formed in the top face of the bearing ring, and the size of an opening of the guide groove is smaller than that of the groove bottom. The camera assembly comprises a bolt, a camera, a connecting piece and a guide piece, wherein the camera, the connecting piece and the guide piece are connected in sequence, the connecting piece is in a U shape,the upper surface of a horizontal plate b is hinged to a shell of the camera, the lower surface of the horizontal plate b is connected with one end of the guide piece, and the guide piece is a rotating piece and is matched with the guide groove, vertical plates a are located on the inner side and the outer side of the bearing separately, the vertical plates a are provided with threaded holes I, the bolt is matched with the threaded holes I, and the tail end of the rod portion of the bolt makes contact with the side wall of the bearing ring. By means of the platform, people can be photographedby various angles at the same time instead of staying at the same position and keeping the same action for a long time, so that the photograph efficiency and the photograph multi-angle stability are improved.

The invention provides a fixing and anesthesia device for mouse magnetic resonance, and belongs to the technical field of medical instruments. When the device is in use, an anesthetic mouse is placed into a mouse placing bin, and the mouse is fixed through a mouth fixing device and ear fixing devices; in the process of a magnetic resonance inspection experiment, continuous low-flow oxygen is introduced to the mouse through an oxygen catheter to prevent the mouse from death in the process of magnetic resonance inspection; if the mouse is awake, in the condition that the posture of the mouse keeps unchanged, a T-branch tube is rotated, and an anesthetic is transported in real time through an anesthetic catheter, so that real-time anesthesia on the mouse is achieved. Therefore, not only is long fixing on the mouse achieved, but the problem of death of the mouse caused by excess anesthetic in single use is avoided, and the structure of the fixing and anesthesia device for mouse magnetic resonance is compact and reasonable, so that it is achieved that the device is matched with an experimental magnetic resonance inspection coil, and the success rate of the magnetic resonance inspection experiment is improved.

The invention provides a moxibustion instrument, which comprises a base, at least one moxibustion clamp and at least one support mechanism, wherein each moxibustion clamp is connected with one end of the corresponding support mechanism; the other end of each support mechanism is connected with the base; a smoke gas purification device and an air extraction device are arranged inside the base; a regulating knob is arranged at the upper end of the base; and a safe protection cover is arranged outside each moxibustion clamp. The moxibustion instrument has the advantages that a moxa roll can be fixed in one position for combustion for a long time; the artificial manual fixation is replaced; the operation is easy and convenient; the moxibustion instrument can be used in various occasions; in the use process, the smoke gas generated through the moxa roll combustion can be absorbed and filtered; and the indoor air is purified.

The invention relates to an air quality detector, which contains an instrument housing, and is characterized in that a detection cavity is arranged inside the instrument housing, a measurement sensor is arranged inside the detection cavity, a fan is arranged inside the detection cavity, a wind inlet is arranged on the front surface of the instrument housing, a wind outlet is arranged on the back surface, the instrument housing is connected to a power supply base, the front surface of the instrument housing is provided with a display screen and operation buttons, the instrument housing is provided with a light sensing sensor, the back surface of the instrument housing is provided with a battery box, a storage battery is arranged inside the battery box, the power supply base is provided with a snapping and connecting groove for snapping the bottom portion of the instrument housing in a connecting manner, and electrodes are arranged on the bottom portion of the instrument housing and inside the snapping and connecting groove. According to the present invention, the air quality detector has two use ways, wherein the instrument housing part can be used in a hand-held manner, and the instrument housing part can be snapped inside the power supply base in the connecting manner so as to be used in a fixed manner for a long time; and the whole detector can be automatically closed in the absence of light.

The invention relates to a method for driving a flat panel display device. In the method, a circumstance that the flat panel display device is significantly attenuated in luminous brightness due to lone-term fixed display through automatically adjusting the display position of a specific image, so that the service life of the flat panel display device is prolonged.

The invention relates to the technical field of agricultural production, and discloses an agricultural greenhouse with high stability. The agricultural greenhouse with high stability includes two supporting columns, fixed blocks are fixedly mounted at the bottom of the two supporting columns, limiting blocks are movably mounted at the top of the two supporting columns, limiting rods pass through the outer sides of the two limiting blocks, clamping blocks are fixedly mounted on the upper sides and the lower sides of the two limiting rods, and the surfaces of the two limiting rods are sleeved with compression springs. According to the agricultural greenhouse with high stability, a bracket can move up and down through the arrangement of the supporting columns and the limiting blocks, and thebracket can be fixed at one position for a long time; through the arrangement of the limiting rods, the compression springs and the clamping blocks, the limiting blocks move on the surfaces of the supporting columns to holes to make the limiting rods clamped in the holes, so that the bracket can be fixed, and the limiting rods are pulled to make the heads of the limiting rods depart from the holes, so that the bracket can move down, thereby facilitating the mounting by users and achieving the effect of convenience in mounting.

The invention provides a needle warming moxibustion device for inserting at least one moxa stick for moxibustion of paitent, and comprises a rectangle like thin frame for paitent to lean against and an inserting net; the frame includes a first side surface close to paitent, and a second side surface opposite to the first side surface; the inserting net is close to the second side surface and parallel to the second side surface and aranged on the frame, and the inserting net comprises many inserting net pores for placing moxa sticks. The invention provides a needl warming moxibustion device for paitent to lean against in a back to back mode and the device can be inserted with many moxa sticks for moxibustion of many acupuncture points of paitent, thereby solving the problems that the prior moxibustion device can be held only or placed on patient body for moxibustion of single acupuncture at the same time, which leads to long treatment process or muscle stiffness and paralysis due to long time immobility.
