The application provides a circuit breaker with a combined protection structure, and belongs to the technical field of circuit breakers, which comprises a circuit breaker body, wire ends arranged at both ends of the circuit breaker body, a control switch connected to the circuit breaker body, a fastening assembly for locking and connecting a conductor, an unlocking assembly for unlocking the fastening assembly, and a limiting assembly for limiting the position of the control switch. The application has the beneficial effects that when the circuit breaker body is used, the clamping and fixing of the conductor can be completed through the cooperation of the pressing roller and the supporting roller, and when the device is tripped due to overload or short circuit, the pressing roller is lifted by the push block through the arc-shaped groove and the limiting clamping rod, so that the conductor is released from the pressing roller and the supporting roller, thereby facilitating the separation of the conductor from the circuit breaker body, reducing the operation steps of maintenance and inspection, and limiting the control switch to further increase the protection effect.

This application relates to an electrical connector, a battery, and an electrical device, specifically in the field of battery technology. The electrical connector includes a first connecting portion, a second connecting portion, a fusible portion, and a first bending portion. The first connecting portion is electrically connected to a terminal post; the second connecting portion is electrically connected to a tab, and the second connecting portion and the first connecting portion are spaced apart along a first direction; the fusible portion connects the first connecting portion and the second connecting portion, and a notch region is formed on at least one side of the fusible portion along a second direction; the first bending portion is located within the notch region and is connected to the second connecting portion, with the first bending portion bent relative to the second connecting portion, and one end of the first bending portion away from the second connecting portion protruding from the surface of the first connecting portion. This electrical connector, battery, and electrical device can prevent misaligned tabs from contacting the first connecting portion after the fusible portion is broken, avoiding reconnection of the battery circuit, eliminating safety hazards, and extending the battery's lifespan.

The present application relates to a fluid hub assembly that allows for an easy connection, a secure connection to a fluid connector, and a safety release mechanism that enables the fluid hub assembly to be safely disengaged from the fluid connector. The fluid hub assembly may include a post and a hub slidably coupled to the post. When disconnected from the fluid connector, the hub may be locked or secured in a latched position, which helps to prevent reconnection or reuse of the hub, thereby facilitating safe and hygienic medical practices.

The invention discloses an adjustable tracheal catheter and endoscope seaming combined device, and belongs to the technical field of gastroscope operation anesthesia equipment. The device mainly comprises a back plate, a gastroscope hole is formed in the surface of the back plate, an up-down adjusting mechanism is fixedly installed at the side end of the gastroscope hole, a caliber adjusting mechanism and a tracheal catheter are arranged at the side end of the up-down adjusting mechanism, the up-down adjusting mechanism comprises a telescopic sliding block, and the telescopic sliding block is installed on the left side of the back plate in a sliding mode. A fixed baffle is fixedly installed at the front end of the telescopic sliding block, the caliber adjusting mechanism comprises a fixed disc, the fixed disc is installed on the middle sections of the telescopic sliding block and the fixed baffle in a sliding mode, the rear end of the telescopic sliding block is in threaded connection with a telescopic rod, and the front end of the telescopic rod is connected with the fixed disc; an adjusting button is fixedly installed at the rear end of the telescopic rod, a clamping groove is formed in the front end of the fixing disc, and a tracheal catheter is arranged at the front end of the clamping groove. By means of the adjustable tracheal catheter and endoscope bite combined device, the effect that the operation process of anesthesia tracheal intubation in a gastroscope operation is simpler, more convenient and safer is achieved.
