The invention provides a remote controller battery bin cloth strip mounting device and a mounting method thereof. The remote controller battery bin cloth strip mounting device comprises a battery bin, a cloth strip hole which is formed in the battery bin and used for mounting a cloth strip, and a circumferential rib part which is arranged at the periphery of the cloth strip hole, made of rubber and is used for fixing the cloth strip by hot ironing. According to the remote controller battery bin cloth strip mounting device, the circumferential rib part can be melted and used for well fixing the cloth strip in the remote controller battery bin; and the device is convenient for industrialization and low in cost, and has high efficiency and long service life.

The invention relates to the field of medical instruments, in particular to a multi-position adjustable nursing bed. The angle and position of a bed body can be controlled and adjusted, so that medical staff can nurse a bedridden patient conveniently. A rotating shaft I penetrates through a shaft hole I and is fixedly connected with a supporting table. An outer adjusting ring is erected to the middle of the supporting table through connection of a shaft hole II and the rotating shaft I. A middle adjusting ring is arranged on the inner side of the outer adjusting ring. Two sets of shaft holes III and shaft holes V are connected through two rotating shafts II respectively. An inner adjusting ring is arranged on the inner side of the middle adjusting ring. Two sets of shaft holes IV and shaft holes VI are connected through two rotating shafts II respectively. A tightening rotary knob is matched with a threaded hole I, a threaded hole II and a threaded hole III. The two ends in the length direction of the bed body are welded to the inner side of the inner adjusting ring. The bottom end of the bed body is fixedly connected to the inner side of the inner adjusting ring through bed body supporting legs. A human body fixing part and the bed body are detachably connected. The bed body and the human body fixing part are connected together through a connection fixing part.

The present invention relates to a molecular-specific detection marker and a detection method thereof for the straw mushroom strain 0229, which is characterized in that: the specific detection marker is a specific primer, wherein the primer sequence is: F: CTTTCAGGAAGAGCCCAGC; R: TGAAGGGCTTGAAGGAGAAA. The detection method includes: inoculate the PDA plate medium with the straw mushroom strain, culture at 32°C for 5 days, scrape the surface mycelium and put it into a sterile centrifuge tube, store it in a refrigerator at -70°C, and then use the improved CTAB method to extract genomic DNA to obtain DNA: the above DNA is used as a template, and the specific detection marker primer is used as an amplification primer, and PCR amplification is performed to obtain a PCR amplification product, which is then detected by electrophoresis. The invention has the advantages of short detection time and high accuracy, uses the obtained molecular markers to identify the straw mushroom strain 0229, is beneficial to the development of the straw mushroom breeding work, and accelerates the research and development of new varieties of the straw mushroom.

A low-resistance multi-position nursing bed comprises supporting frames symmetrically arranged at two ends, adjusting devices arranged in the two supporting frames and a bed body, wherein each adjusting device comprises an outer ring body, a middle ring body and an inner ring body, two outer ring rotation shafts extending out horizontally and outwards pass through the left side and the right side of the outer ring body in the horizontal diameter direction and are installed in horizontal rotation shaft holes formed in the upper ends of the two supporting frames to form a rotating pair A, positioning mechanisms A for positioning the outer ring rotation shafts are arranged at the upper ends of the supporting frames, the middle ring bodies are installed in the outer ring bodies in the mode similar to the above mode, the inner ring bodies are also installed in the middle ring bodies through similar structures, and the bed body comprises a bed board fixed inside the inner ring bodies and a human body fixing device for fixing a human body. The low-resistance multi-position nursing bed enables a patient to be arranged at the rotation center, the resistance in the rotation process is small, any person can perform operation, the nursing difficulty can be remarkably reduced, and especially for patients with big weights, the characteristic of small resistance of the nursing bed is prominent.

The invention provides an automobile seat armrest. a clamping spring capable of tightly holding and locating a shaft rod sleeves the fixed end of a supporting plate of the automobile seat armrest; theclamping spring is a clamping spring made of a square material; one end of the clamping spring is fixed on the supporting plate by using a fixing block; the other end of the clamping spring is positioned under a twisting plate; and a locating rotating clamping block is arranged on one side of the twisting plate. While being in use after being mounted, the automobile seat armrest can be adjusted at any will; when one end of the automobile seat armrest is lifted, the clamping spring is loosened by the clamping block, and the automobile seat armrest is located by releasing the armrest clamping spring; and therefore, a purpose of adjusting a seat backrest at any will is achieved.
