A multi-joint bionic dexterous artificial hand finger belongs to the technical field of mechanical bionic hands and comprises a finger body. The rotating mechanism is arranged in an inner cavity in one side of the finger body, the rotating mechanism comprises a first rotating rod, one end of the first rotating rod penetrates through the finger body and is fixedly provided with a fingertip, and the surface of the first rotating rod is fixedly provided with a limiting ring located in the finger body; in the rotating process of a limiting ring, a first rotating rod and a fingertip can be limited, then the fingertip can drive a protective sleeve to rotate by 180 degrees, then the protective sleeve can move to the top end of a finger body, and then the finger body and the protective sleeve can grab fragile objects; and finally, the fingertips are rotated by 180 degrees through the driving motor, so that the grabbing state of the finger body can be flexibly adjusted according to the characteristics of an object, and the adaptability and universality of the finger body in practical application are improved.

The utility model discloses an outdoor sports glove, and belongs to the technical field of sports gloves. An outdoor sports glove comprises a glove body, a ventilation window is formed in the palm center of the glove body, the surface of the ventilation window is covered with a sweat absorption belt, the sweat absorption belt is annularly arranged and arranged on the glove body in a penetrating mode, the width of the sweat absorption belt is larger than that of the ventilation window, the outer side of the sweat absorption belt is made of silica gel materials, and the inner side of the sweat absorption belt is made of porous water absorption materials. The porous water absorption material is formed by blending polyester fibers and cotton fibers, so that the inner side of the sweatband has hygroscopicity, and the abrasive resistance of the sweatband can be guaranteed. When the palm center of a user sweats, the sweat absorbing belt located at the ventilation window can absorb sweat; due to the fact that the sweatband is arranged on the glove body in the penetrating mode, the palm center and palm back positions of the sweatband are changed by pulling the sweatband, and the palm part can be kept dry. Meanwhile, the sweatband can cover the ventilation window all the time, and the hand is protected.

The invention relates to the field of film cutting, in particular to a multi-shaft linkage self-positioning type film cutting device and a photogravure press, the multi-shaft linkage self-positioning type film cutting device comprises a rack, a conveying mechanism and a cutting tool, the conveying mechanism and the cutting tool are arranged on the rack, a platform is arranged on the rack, a positioning mechanism is arranged on the platform, and the positioning mechanism comprises two sets of rolling shafts used for clamping a film; one group of rolling shafts are movable rolling shafts located at the front end of a thin film conveying path, the other group of rolling shafts are fixed rolling shafts located at the tail end of the thin film conveying path, and an anti-deviation structure used for being in linkage with a cutting tool in a matched mode to further fix the thin film is arranged over the platform and located between the movable rolling shafts and the fixed rolling shafts. The fixed rolling shaft and the movable rolling shaft cooperatively work to jointly clamp the film and prevent deviation, then the trigger piece moves along with the cutting tool to synchronously drive all the extrusion pieces to make close contact with the film, the air bag expands along with the trigger piece to tightly abut against the film, and the fixing effect is further enhanced.

The utility model discloses a sensor, which comprises a shell, a base and a sensing assembly, wherein the base is provided with a first port and a second port which are opposite to each other, the first port is connected with the shell, the shell and the base jointly form a first cavity, and at least one part of the sensing assembly is located in the first cavity; the sensing assembly comprises a circuit board, a temperature sensing structure and a strain type pressure sensing structure, the temperature sensing structure and the strain type pressure sensing structure are electrically connected with the circuit board, and at least one part of the temperature sensing structure extends out of the second port of the base from the fluid channel in the first cavity so as to sense the temperature of an external medium; and the strain type pressure sensing structure is communicated with the fluid channel so as to sense the pressure of the external medium. The pressure sensor can sense the temperature and the pressure of an external medium at the same time, and is high in sensing precision and simple in structure.

The application discloses a bone conduction earphone, which comprises two earphone heads (1), two warehouse bodies (2), ear hanging lines (3) connected between the earphone heads (1) and the warehouse bodies (2), and neck wearing lines (4) connected between the two warehouse bodies (2). When the neck wearing line (4) is in a horizontal state, the warehouse body (2) extends vertically downward or extends downward and inclines toward the side where the earphone head (1) is located. In the application, the center of gravity of the warehouse body is closer to the fulcrum where the ear hanging line contacts the ear, the center of gravity of the whole bone conduction earphone is closer to the front, the tendency of the bone conduction earphone to swing around the fulcrum during movement is inhibited, the swing amplitude is reduced, the bone conduction earphone is more stable and reliable when worn on the head, and the use experience is better.
