The utility model provides a power supply site safety distance audible and visual alarm. The power supply site safety distance audible and visual alarm comprises a mounting seat, an alarm connected below the mounting seat, a driving assembly connected to the mounting seat, and a clamping assembly pivotally connected to the driving assembly. The clamping assembly comprises two clamping arms which pivot relatively, elastic bodies connected to the clamping arms and bearing parts arranged at the pivot centers of the clamping arms. A wrapping space is formed between the two clamping arms, the two elastic bodies are oppositely arranged in the wrapping space, and each elastic body comprises a curled part protruding towards the center of the wrapping space. A pivot shaft of the two clamping arms is elastically connected with a bearing part, a connecting piece is further arranged between the bearing part and the curling parts, when the driving assembly drives the two clamping arms to be close to each other, the ends of the two curling parts move in the direction away from the center of the wrapping space, the bearing part moves upwards, and a clamping space is defined by the bearing part and the two curling parts. According to the utility model, the alarm and the high-voltage wire are fastened, and the warning and protection effects of the high-voltage wire are ensured.

This utility model discloses an upper limb exoskeleton, relating to the field of industrial assistive device structural design technology. The upper limb exoskeleton includes: a shoulder restraint, a waist restraint, an upper arm fixation, a shoulder rotation mechanism, and an assist mechanism. The lower side of the shoulder restraint is connected to the waist restraint, and an assist mechanism is provided below the shoulder restraint. The lower end of the assist mechanism is fixedly connected to the waist restraint, and the upper side of the assist mechanism is fixedly connected to the shoulder rotation mechanism, which is connected to the upper arm fixation. This upper limb exoskeleton provides support and fixation for the user's upper body through the shoulder and waist restraints. To achieve a lightweight design, assist mechanisms are provided on both sides of the shoulder restraint. The rotation of the shoulder rotation mechanism causes the internal tension springs of the assist mechanism to elastically deform and return to their original position, providing mechanical assistance for shoulder movement and ensuring the stability of the assist mechanism. It is adaptable to users of different body types, ensuring flexible movement with multiple degrees of freedom.

This invention relates to a fertility assistive device (1) and an inserter (2) suitable for insertion of the fertility assistive device (1) into or near the cervix (CX) of the vagina of a mammal (preferably a human). The fertility assistive device (1) includes a cylindrical collector (CR) comprising an edge (RI) having one or more protrusions on its surface, which are adapted for easy removal after a final procedure. The cylindrical collector (CR) also has a base (BP) and sidewalls (SW) extending from the base to the edge (RI). The sidewalls (SW) include one or more crease lines (FL, FL') that allow the cylindrical collector (CR) to fold inward radially according to a predetermined shape. The inserter (2) includes an inner tube (IT) suitable for insertion into an outer tube (OT). The inserter (2) is provided with an insertion operation mode and a release operation mode, wherein the inserter (2) is adapted to be locked in both operation modes by rotating the two tubes (IT, OT) relative to each other, thereby facilitating easy insertion of the fertility aid (1) into or near the user's cervix (CX).
