The self-locking mechanism of this application can realize the automatic locking of the movable rod.

The utility model discloses a packaging box for an oral mucosa sample collection kit, and relates to the field of oral instruments. The sampling device packaging box comprises a packaging box body, a cavity used for containing sampling devices is formed in the inner side of the packaging box body, a plurality of limiting parts and a suction cup part are arranged on the inner side of the cavity, through the suction cup part, after a user places the packaging box body on an operation table top, a limiting piece of the suction cup part is pressed, a telescopic rod is driven to stretch out downwards, and the sampling devices are arranged on the suction cup part. The bottom sucker is directly adsorbed to a table top, the box body is rapidly fixed through the negative pressure effect, the packaging box is prevented from sliding or toppling over during operation, meanwhile, the elastic piece can absorb part of acting force generated when the packaging box body moves, direct influence of the acting force on the sucker structure is reduced, and the elastic piece absorbs external force through self deformation. Impact of actions of a user on the packaging box is counteracted, and adsorption stability is maintained.

The utility model provides a water conservancy project pipe -in -place wire -laying device relates to pipe -in -place wire -laying technical field, the utility model discloses a measurement casing, one side outer wall of measurement casing is fixedly connected with the swivel plate along the horizontal direction, the output of swivel plate is fixedly connected with the tape roll along the horizontal axis direction, the outer circumferential surface of tape roll is wound with the measurement scale band, one end of measurement scale band is fixedly connected with the end of tape roll. The utility model discloses, through setting up detachable main counter weight and vice counter weight, the flexible adjustment of counter weight is realized with cooperation connecting device. When outdoor wind power is bigger, can install vice counter weight through the cooperation of rectangular connecting block and rectangular slot fast, utilize the clamping structure of wedge -shaped clamping block and clamping groove to ensure that the connection is stable, significantly increase the overall counter weight, effectively offset the impact of wind power to the scale band, avoid the scale band to shake, ensure that the measurement scale band always keeps vertical straight state in the wire -laying process, improve the accuracy of pipe -in -place path measurement.

The invention relates to the technical field of anti-cutting glove processing equipment, and discloses automatic detection equipment for anti-cutting glove processing, which comprises a base, and further comprises a detection part mounted on the base; the mounting part is arranged on the front side of the base; the moving part is positioned in the base; the detection part comprises a balance assembly, and the balance assembly is installed in the base; the downward pressing assembly is located on the front side of the base; the balance assembly comprises a first support arranged on the front side of the base, a first electric telescopic rod is fixedly connected to the inner wall of the base, and the output end of the first electric telescopic rod is fixedly connected with the first support.
