The application discloses a disassembling device for disassembling a wedge key of a crushing device, which comprises a connecting support fixedly arranged for being connected with the crushing device, and a puller assembly capable of moving relative to the connecting support. The puller assembly comprises a positioning member for holding the wedge key to be disassembled and a pull rod. The connecting support is provided with a movable cavity for accommodating the positioning member. The positioning member is movably arranged in the movable cavity. One end of the pull rod is movably arranged on the connecting support. At least one end of the pull rod extends into the movable cavity and is connected with the positioning member, so as to drive the positioning member to move in the movable cavity, adjust the remaining space in the movable cavity, adapt to different pulling strokes, and disassemble the wedge key.

The utility model relates to an electronic ice tank assembly structure, and its technical scheme main points are: including: shell, and inner bag, the inner bag is placed in the inner side of shell, the one end of inner bag is relatively provided with water inlet and water outlet, is provided with water inlet joint on water inlet, is provided with water outlet joint on water outlet, the other end of inner bag is provided with drain pipe, one side of inner bag is provided with square hole, the periphery of square hole is provided with boss, is provided with containing groove around the opening, is equipped with sealing ring in containing groove, is provided with square boss in the periphery of square hole of inner bag, and is provided with containing groove of adapting with sealing ring on boss, effectively prevent sealing ring from deviating, strengthened the leakproofness, reduced the risk of water leakage and circuit short-circuit, improved the reliability and security of electronic ice tank, through setting up water inlet joint and water outlet joint make the connection and remove more convenient, efficient, labor saving, promoted the installation efficiency, can bear greater pressure, firmness is stronger, reduced the water leakage situation.

This utility model relates to an impact tool, comprising: a main body, an impact member, and a hammering member. The main body includes an internal space, an impact chamber, and a insertion hole arranged sequentially along a first direction. The internal space and the impact chamber are interconnected, and the insertion hole connects to the impact chamber for an object to be impacted to pass through. The impact member is used to impact the object to be impacted. The impact member is movable from a first position to a second position within the impact chamber along the first direction. When the impact member is in the first position, it does not protrude from the insertion hole in the first direction, and a portion of the impact member protrudes into the internal space. The hammering member is movable back and forth within the internal space along the first direction to hammer the impact member and force it to move along the first direction.
