A leveling device for laying tiles or the like includes a tie-rod having a support base for edge portions of one or more adjacent tiles, a projecting element from the base, which can be arranged into junctions between adjacent tiles, and a knob coupling with the projecting element and having an outlet pass-through hole for a free end of the projecting element. The knob is configured to force an edge portion of the adjacent tiles against the base to level the placement and is configured to receive and retain, by snap coupling elements, a blocking tie-rod hooking and retaining the projecting element inside a pass-through channel defined in the blocking tie-rod. The blocking tie-rod is sectioned into two coupling half-shells, embracing and constraining the projecting element when inserted in the cap, and mutually separating to leave free the projecting element when at least partially extracted from the cap.

Air bags (220A, 220B) are provided respectively to two mutually opposing planar surfaces of an inner peripheral surface of a cylindrical member (210). When retrieving a polycrystalline silicon rod (11), the cylindrical member (210) of a carrying tool (200) covers the polycrystalline silicon rod (11) (pair) from above to accommodate the polycrystalline silicon rod (11) therein, and when gas is injected into the air bags (220) to inflate the air bags (220), the air bags (220) press against the side surfaces of the polycrystalline silicon rod (11) from the direction orthogonal to the planar surfaces including both gateway-shaped pillar members, and hold the polycrystalline silicon rod (11) in the cylindrical member (210). As a result, collapsing of the polycrystalline silicon rod (11) is avoided, even if cracks have formed in the polycrystalline silicon rod (11), as external impacts are absorbed by the air bags (220).

A microwave oven incorporating toaster includes a tray provided on a tray support. The tray support moves forward and backward in inside the toaster. The tray support includes a bushing for moving within moving slots provided at both sidewalls of a toaster case. A connecting lever connects the bushing to a toaster door and translates a motion generated by operation of the toaster door when it opens and closes into a moving motion exhibited by the tray. A food item (e.g., a slice of bread, bagel, etc.) arranged on the tray may be inserted into, or removed from, the inside of the toaster by operating the toaster door.

The engagement portion is to be engaged with the attachment portion, and the support portion is supportable with a palm and grippable with digits of a hand.

The invention discloses a device for dismantling building components, and specifically relates to the technical field of dismantling building materials. The top of the sliding bracket is hingedly provided with an overturning seat, and an overturning oil cylinder is hinged between one side of the bottom of the fixed support frame and one end of the overturning seat. The clamping plate is fixed, and a clamping cylinder is fixedly arranged inside the turning seat. In the present invention, the building components are clamped and fixed by means of the movable clamping plate and the fixed clamping plate, and the subsequent overturning support plate is turned over, so that the disassembled building components correspond to the inclined sliding support, and cooperate with the sliding roller to slide down along the sliding support , to facilitate the disassembly and removal of building components, avoiding the direct disassembly and dropping of components, avoiding the splashing of component debris, and improving the safety effect of disassembly.
