The utility model discloses a stack spraying clamp device with an improved structure. The stack spraying clamp device comprises a clamping bottom plate, a clamping cover plate, a locking bolt and a plurality of clamping middle plates, wherein the clamping bottom plate is provided with a bottom plate positioning convex column, the clamping cover plate is provided with a cover plate positioning convex column, and the clamping middle plates are provided with middle plate positioning convex columns; a bottom plate through hole is formed in the clamping bottom plate, a cover plate through hole is formed in the clamping cover plate, the locking bolt comprises a limiting blocking part, a straight rod part and an elastic inserting and buckling part, and an elastic piece is arranged at the position, above the limiting blocking part, of the lower end of the straight rod part; the clamping cover plate is provided with a cover plate profiling positioning pin, and each clamping middle plate is provided with a middle plate profiling positioning pin; the elastic inserting and buckling part comprises two elastic buckling arms, and an arc-shaped bent middle connecting part is arranged between the two elastic buckling arms. By means of the structural design, the clamp has the advantages of being novel in structural design, good in stability and reliability and high in clamping accuracy.

The medical knife according to the present invention holds a knife body by means of a holder and a cover, and is configured so that the knife body has: a blade edge that extends from a blade tip in plan view and has a blade edge in at least a portion thereof; a back edge extending from the tip; and a first edge portion extending in a direction having a first angle with respect to the back edge, the holder having a concave blade body holding recess formed along the shape of the blade body, the blade body holding recess has a first inclined portion inclined in a direction perpendicular to the first edge portion in a plan view at a position where the first edge portion abuts, and a second inclined portion inclined in a direction perpendicular to the back edge in a plan view at a position where the back edge abuts.

This utility model relates to a track spotlight. It forms a two-dimensional elastic positioning structure by setting a first elastic positioning component between the track power box and the support rod, and a second elastic positioning component between the support rod and the lamp tube. The first elastic positioning component allows the support rod to rotate the lamp tube 360° horizontally, while the second elastic positioning component allows the lamp tube to swing at multiple angles vertically. The elastic force of the components consistently provides stable support to the adjusted position, avoiding the positioning failure issues of traditional damping structures due to wear or the cumbersome adjustment of bolt structures. This ensures the lamp tube remains stable at any preset angle, effectively improving lighting accuracy.

本实用新型属于分体式充填液压支架技术领域，具体公开了一种充填隔离架体及分体式充填液压支架。本实用新型的充填隔离架体，将其应用于分体式充填液压支架，在第一液压缸的推动下，上隔离体能沿着竖向移动，在第二液压缸的推动下，下隔离体能沿着竖向移动，同时，上隔离体和下隔离体沿着前、后方向保持层叠布置，充填隔离高度由上隔离体的上端与下隔离体的下端之间的距离限定，如此，以根据回采工作面的采高灵活调节充填隔离高度；底座与导向支撑架呈L形布置，并且，导向支撑架与导向座嵌套布置，使得隔离体能在膏体凝固过程对膏体进行稳定的支撑。

The invention discloses a battery releasing device and a battery charging box. The battery releasing device comprises a base component which is provided with a battery accommodating cavity and a plurality of pairs of conductive terminals; the bottom of the base component is provided with a release opening allowing the battery to fall off. The movable component is configured to move relative to the base component, the movable component comprises a plurality of abutting and pushing parts, and the abutting and pushing parts can be driven to move between a retreating position and a pushing-out position; and the linkage supporting pieces are arranged at the releasing openings, and the linkage supporting pieces are in linkage fit with the abutting and pushing parts so that the linkage supporting pieces can be driven by the movable component to be switched between the supporting state and the releasing state. When the pushing part is in the retreating position, the plurality of linkage supporting pieces are in a supporting state to shield the release opening, so that the battery can be assembled and supported in the battery accommodating cavity so as to be electrically contacted with the conductive terminal; and when the pushing part is in the push-out position, the plurality of linkage supporting pieces are in a release state to open the release port, and the battery is pushed by the pushing part to be separated from the conductive terminal and fall off from the release port.
