The application relates to the cable technical field, in particular to a cable used in a low-temperature environment, which comprises a center cable, a plurality of integrated cables arranged around the center cable, and a plurality of restraining members, the number of the restraining members is the same as that of the integrated cables, the length direction of two adjacent integrated cables is limited by one restraining member, and the plurality of restraining members limit the plurality of integrated cables to be an integral annular layer in the annular direction. After accepting the external temperature, the aluminum foil film of the capsule-shaped space is rapidly heated, at which time the aluminum foil film melts the paraffin particles in the interior, so that the paraffin particles are melted, the paraffin has excellent heat preservation effect as a heat accumulator, can better preserve the temperature, so that the outer sheath can be kept at a suitable temperature, which is beneficial to protecting the outer sheath used in the low-temperature environment and can improve the service life of the outer sheath, and then the outer sheath can reversely preserve the temperature of the external adjusting sleeve, increase the temperature preservation time of the external adjusting sleeve, and reduce the frequency of external heat supply.

The invention discloses an automobile part anti-bending strength detection device, and particularly relates to the technical field of detection devices, the automobile part anti-bending strength detection device comprises a detection base, a detection seat, a lifting unit, a connecting column, a floating column and a limiting unit; the detection pressing block is fixedly connected to the lower end of the floating column and is positioned right above the detection seat; and the trigger unit is arranged on the detection seat, is positioned below the detection pressing block, and is matched with the limiting unit, so that the floating column freely slides in the connecting column. Through the arrangement of the trigger unit and the limiting unit, when the pressure of the pressing block on the automobile part is detected to be too large, and the downward bending angle of the automobile part is increased, the trigger unit triggers the limiting unit to act, so that the locking and limiting effect of the limiting unit on the floating column disappears, and then the floating column can freely slide in the connecting column; in this way, the extrusion force of the detection pressing block on the automobile part disappears rapidly, and the automobile part is prevented from being broken due to the too large bending angle.

The invention relates to the technical field of medical instruments, and discloses a fixing device for assisting in fixing hip and leg positions for radiotherapy, which comprises a main body and two rotary connectors fixedly connected to the left side and the right side of the main body respectively, and further comprises a lifting mechanism arranged between the two rotary connectors, the lifting mechanism comprises two lifting frames, and the two lifting frames are rotationally connected between the two rotating connectors correspondingly.
