The invention discloses a transport case convenient to use, which comprises a case body. The bottom of the case body is fixedly connected with a fixed box, the both sides of the inner wall of the fixed box are fixedly connected with vertical plates, and one side of the inner wall of the vertical plate is in sliding connection with a movable plate; one side of the movable plate away from the innerwall of the vertical plate penetrates through the vertical plate to extend to the outer portion of the vertical plate, the bottom of the movable plate is fixedly connected with a supporting plate, andthe bottom of the supporting plate penetrates through the vertical plate to extend to the bottom of the vertical plate; the bottom of the regulating device penetrates through the fixed box to extendto the bottom of the fixed box, the bottom of the regulating device is fixedly connected with a baseplate, and the both sides of the upper portion are fixedly connected with push plates. The transportcase relates to the technical field of the machinery and transport equipment, is convenient to use, and effectively switches between move and fixation. Manual switch is convenient to operate, the transport case can't fall off in a state of chucking so as to ensure a normally convenient use and reduce wastes.
