A folding ladder with handrails comprises a ladder body and a handrail structure. The ladder body comprises two front leg tubes, two rear leg tubes, a folding step structure, an inverted U-shaped support and several rear cross beams. The handrail structure comprises two handrail components. The two handrail components are symmetrically arranged on the left and right sides of the ladder body. The handrail component comprises a fixed rod, a rotating rod and a handrail rod. One end of the fixed rod is fixedly connected with the outer side wall of the rear leg tube. The other end of the fixed rod extends upward and the extending direction is consistent with the rear leg tube. One end of the rotating rod is hingedly connected with the outer side wall of the front leg tube. The handrail rod is hingedly connected between the fixed rod and the rotating rod. When the ladder body is completely unfolded, the handrail rod is parallel to the front leg tube, and the rotating rod is parallel to the fixed rod. The handrail structure of the utility model can be automatically folded and unfolded with the ladder body, and the user does not need to manually operate the handrail structure, so that the folding and unfolding process of the handrail structure is more quick and convenient.

This invention provides a bolt structure tensile strength testing device, relating to the field of bolt technology. It includes a placement mechanism with a component to be tested slidably connected inside. The placement mechanism includes a base plate, a first placement plate fixedly connected to one side of the top of the base plate, and a second placement plate slidably connected to the inner wall of the base plate. A set of first fixing members are fixedly connected to the inner walls of the first and second placement plates. A first electric push rod is fixedly installed on the inner walls of the first and second placement plates. The design of the first and second placement plates facilitates the user in placing the bolt inside, changing the previous method of using a single unit. Through the cooperation of the first electric push rod, guide rod, first fixing member, second fixing member, and nut, the bolt body can be stably positioned inside the first and second placement plates, indirectly ensuring the normal operation of subsequent work.
