The portable anti-drop ultrasonic flaw detector includes a pull rod, and a detector body, a hand grip is connected in the middleposition above the pull rod, the pull rod is connected to the exterior of a fixing rod by a bearing, two sides of an external part of the top end of the fixing rod, which penetrate through an externalframe body, are separately arranged inside a first fixing base and a second fixing base, the top end of a push rod is in axis connection with a clamping ball through an installing plate, the clampingball is clamped inside a clamping groove, and the clamping groove is embedded in the surface of the inner wall of the first fixing base. During a use process of the entire portable anti-drop ultrasonic flaw detector, it is not only convenient to carry the detector, the detector body can be also well protected when the detector is carried and used, and damages will not occur. In addition, the angle of the body of the entire detector can be adjusted flexibly, and unstable placement of the detector body can be avoided.

The invention provides a lifting device for a physical experiment. The lifting device comprises a push seat, moving brake wheels, a fixing seat, a first connecting rod, a rotating rod, a classification storage push rod structure, a rotatable adjusting support frame structure, a plug-in storage frame structure, an adjustable lighting cover structure, a sliding hole, a sliding rod, a threaded rod, arotating plate, a first connecting seat, an experimental table and a first supporting rod, wherein that moving brake wheels are respectively bolted at the four corner positions of the lower end of the push seat. Cooperating of the fixing seat of that invention, the first connecting rod, the rotating rod, the sliding hole, the sliding rod, the threaded rod, the rotating plate and the first connecting seat with each other is beneficial to rotating the rotating plate to drive the threaded rod to rotate during the experiment, so that the first connecting rod moves to the middle, drives the rotating rod to rotate, adjusts the height of the experiment table, reversely operates to reduce the experiment table, and facilitates people of different heights to carry out experiments and increase the adjustment function.
