The folding ladder comprises a first ladder foot, a second ladder foot, a pedal and a lock catch structure, the upper ends of the first ladder foot and the second ladder foot are movably connected with each other, the lower ends of the first ladder foot and the second ladder foot are supported on the ground, the pedal is movably connected with the first ladder foot and the second ladder foot, and the lock catch structure is provided with a handle plate, a lock hook, a connecting rod and an elastic piece; the handle plate and the lock hook are movably connected with the pedal through the connecting rod, the connecting end of the lock hook is movably connected with the handle plate and the pedal through the connecting rod, and the locking end of the lock hook is used for hooking the reinforcing rod of the first ladder foot or the second ladder foot; the elastic piece is arranged on the connecting rod in a sleeving mode, elastically connected with the pedal and the lock hook and used for enabling the locking end of the lock hook to hook the reinforcing rod when the lifting handle plate overturns downwards and driving the locking end of the lock hook to be separated from the reinforcing rod through the limiting piece when the lifting handle plate overturns upwards. Therefore, the structure of the lock catch structure is simplified, the lock catch structure is easy to process and produce, convenient to replace and maintain in actual use, higher in operation flexibility and humanized in design.

The utility model discloses a straight arm car upper control box belongs to straight arm car upper control box field. Including upper control box body, the upper control box body top is provided with the upper cover, the left side of upper control box body is provided with the side cover, the upper surface of upper cover is provided with the indicator light panel, the upper surface of upper cover and located the left of indicator light panel is provided with the speed potentiometer, the upper surface right rear of upper cover is provided with the emergency stop button, through the cooperation of bottom plate, fixed block, screw rod, screw bush, moving block etc. parts'synergistic effect, the operator only needs to rotate knob, can drive upper control box body rotation pivot and rotating block's connecting shaft realizes angle regulation. This design breaks the traditional upper control box fixed angle's limitation, can satisfy the operation habit of different operators, has improved the comfort and the convenience of operation obviously, helps to reduce the operation fatigue, improves the work efficiency.
