Claims (1)

[Claims for Utility Model Registration] (1) One end is connected to a link mechanism that operates a stretcher fixing device that fixes a fixed device provided on the lower surface of the stretcher to a stretcher mounting device, and the other end is attached to a handle. At the same time, the base near the handle is taller than the tip,
A handle shaft that is biased toward the link mechanism, a first rotating shaft that is installed in a direction that intersects the direction in which the stretcher enters, and a rotation center that is centered on the first rotating shaft and is located below the position where the stretcher is expected to pass the fixed device. a first rotating member that is installed at the base and is always biased upward by a spring;
A second rotating shaft is provided in a direction intersecting the first rotating shaft and is closer to the handle than the first rotating shaft, and the second rotating shaft is the rotation center, and the end of the second rotating member on the first rotating member side is A stretcher mounting device comprising a second rotating member located below the first rotating member, the other end of which is normally placed on the base of the handle shaft and always biased downward by a spring. Locking device for stretcher fixation device. (2) The tip is connected to a link mechanism that operates the stretcher fixing device that fixes the fixed device provided on the underside of the stretcher to the stretcher mounting device, the other end is attached to the handle, and the base near the handle is attached to the tip. a handle shaft having a height compared to that of the stretcher; a first rotating shaft installed in a direction that intersects the direction of approach of the stretcher; a first rotating member that is installed and always biased upward by a spring and whose surface slightly bulges to a medium height, and a second rotating member that is provided in a direction that intersects the first rotating shaft and is closer to the handle than the first rotating shaft. 2 rotating shafts, and the second rotating shaft is the center of rotation, the end of the second rotating member on the first rotating member side is located at the bottom of the first rotating member, and the other end is usually placed on the base of the handle shaft. 1. A locking device for a stretcher fixing device in a stretcher mounting device, characterized in that the locking device comprises a second rotary member which is always biased downwardly by a spring.
