The utility model relates to a current clamp and clamp type current monitoring equipment, and belongs to the technical field of current monitoring. The utility model provides a current clamp which comprises a shell, two clamp bodies and a linkage assembly, each clamp body comprises a driving section and a clamping section which are connected, the driving sections of the two clamp bodies are rotationally connected with the shell so that the two clamp bodies can be in an open state and a closed state, the clamping sections are in an arc shape, and when the two clamp bodies are in the closed state, the two clamp bodies can be driven by the linkage assembly. The two clamping sections abut against each other and enclose to form a closed clamping ring; the linkage assembly comprises a pushing piece arranged between the two clamp bodies, and the pushing piece is at least connected with one clamp body so as to drive the other clamp body to rotate reversely when one clamp body rotates at least in the process that the two clamp bodies are converted from the closed state to the open state. The current clamp and the clamp type current monitoring device at least solve the problem that in the prior art, the action stroke of the current clamp is long in the opening and closing process.

A novel automatic reset fixture, relating to the field of aging testing equipment technology, is used for aging testing of devices. From bottom to top, it includes a base plate, a PCB matching board, and a probe limiting plate capable of supporting the device. The PCB matching board has a number of auxiliary probes, and the probe limiting plate has through holes for the auxiliary probes to pass through. Fixture assemblies are respectively arranged on both sides of the PCB matching board. The fixture assemblies include a lower support plate, an upper pressure plate, a flipping plate, a lower pressure plate, two guide shafts, and two compression springs. This fixture is adapted to the automation, flexibility, and intelligent production needs of modern manufacturing, achieving an overall improvement in production quality, efficiency, safety, and control levels through technological optimization, providing reliable tooling support for the stable and efficient operation of the entire production process.

The utility model relates to a hinge device for opening and closing a cabinet door. The hinge device comprises a hinging part, a spring assembly, a hinge arm and a connecting shaft, the hinge part comprises a mounting plate which is detachably fixed on the cabinet door, a first hinge seat which is integrally formed and fixed at the top end of the mounting plate, and a second hinge seat which is integrally formed and fixed at the bottom end of the mounting plate; the spring assembly comprises a first spring and a second spring, the upper end of the second spring is embedded in the first spring, the first spring is fixedly connected with the bottom end of the first hinge base, the top end of the second spring abuts against the bottom end of the first hinge base, and the bottom end of the second spring abuts against the top end of the second hinge base; one end of the hinge arm is connected with the first spring, and the other end is fixedly connected with the cabinet body; the connecting shaft penetrates through the first hinge base, the spring assembly and the second hinge base. The utility model has the advantages of easy opening and closing, increased opening and closing angle, improved connection stability and prolonged service life.

The utility model relates to the field of medical instruments, and discloses a cover body opening and closing structure of a salt sol generating device, which comprises a shell and a cover body, a column foot is arranged at the end part of the shell and is fixedly connected with the shell, a pin hole is formed in the top of the column foot, the cover body is hinged with the shell through a U-shaped connecting piece, one end of the connecting piece is fixedly connected with the cover body, and the other end of the connecting piece is fixedly connected with the shell. The diameter of the connecting column is smaller than the inner diameter of the pin hole, the connecting column can be inserted into the pin hole and can freely rotate in the radial direction, a U-shaped groove is defined by the connecting piece and the cover body, the end of the shell is arranged to be in an arc shape, and the distance from the pin hole to any position of the end of the shell is smaller than the width of the opening. And when the cover body is opened, the end part of the shell extends into the U-shaped groove of the connecting piece from the opening. According to the utility model, no gap exists between the cover body and the shell in the opening and closing processes, so that the risk that hands are pinched is avoided; meanwhile, in the opening and closing process, the cover body and the shell do not make contact, and the risk of damage caused by collision and friction is avoided.
