Abstract: A soldering iron head includes a bottom surface, a first side surface, a second side surface opposite to the first side surface, and a positioning slot formed on the bottom surface and extending between the first side surface and the second side surface. The positioning slot is adapted to accommodate and position an exposed end conductor of a cable. The cross section of the positioning slot is trapezoidal in shape, absent a lower bottom. An upper bottom facing side of the trapezoidal cross section of the positioning slot gradually increases in width from the first side surface to the second side surface.

Abstract: Disclosed is a double-layer mattress cover, comprising an upper cover body and a lower cover body, wherein one end of the upper cover body is integrally connected to an upper end of the lower cover body, and an edge of the upper cover body is separably connected to the lower cover body by means of a connector. One mattress is assembled in a cavity defined by the upper cover body and the lower cover body, and the other mattress is directly assembled by means of a cover opening formed in the lower cover body, such that two mattresses can be assembled in the mattress cover at the same time. Moreover, the lower cover body is located blow the upper cover body, such that when only one mattress is assembled, the lower cover body can be directly placed below the mattress to be hidden.

Abstract: A multi-rule decision method of evaluating comprehensive performance of a battery stack includes selecting multiple indexes affecting the performance of the battery stack as a single-performance decision rule of the battery stack to form a decision rule vector. The method includes based on classical best worst method, obtaining a weight of each evaluation person of the comprehensive performance of the battery stack for the single-performance decision rule of the battery stack in the decision rule vector. The method includes based on entropy theory, aggregating the weight of the single-performance decision rule of the battery stack determined by each evaluation person of the comprehensive performance of the battery stack to obtain an importance weight of the evaluation persons of the comprehensive performance of the battery stack satisfying the iteration stop condition and a final comprehensive weight of the single-performance decision rule of the battery stack.

Abstract: A multi-gear adjustable support mechanism includes a base plate, a support plate, a support element, a gear forming element having gear grooves and a limiting part and a gear controller having an abutting part and a platform. The support element includes a support crossbar for supporting the support plate at a different angle from the base plate. A moving surface of the gear forming element bears and supports the movement of the support crossbar. The platform is aligned with the moving surface at the position of the gear groove closest to the limiting part when the support crossbar moves and reaches the limiting part. The support crossbar moves on the surface of the platform part and passes the gear groove when the support crossbar returns from the limiting part. An adjustable seat is provided including the multi-gear adjustable support mechanism.
