the wedge-shaped structure is driven to move in a direction away from or close to the vertical abutment portion, so that the sliding seat can drive the positioning pin to lock or separate with the first rotating connecting plate under the action of the first compression spring; The first rotating connecting plate is also provided with a plurality of latch holes, which are distributed in a circular array on the first rotating connecting plate, and any one of the latch holes can be plugged and matched with the positioning pin when rotating to a position corresponding to the positioning pin; It also includes a handle assembly; the handle assembly includes a handle fixing seat, a first slider connecting plate, and a handle assembly; the handle fixing seat is fixedly mounted on the first support frame; the first slider connecting plate is fixedly mounted on the first slider; the handle assembly includes a handle connecting rod and a handle fixed to the top of the handle connecting rod; the handle connecting rod is hinged to the handle fixing seat; the bottom of the handle connecting rod is provided with two parallel vertical clamping parts, and the bottom of each vertical clamping part is provided with a roller, and the two rollers clamp the first slider connecting plate; the handle assembly is used to drive the first slider to move in a direction away from or close to the vertical abutment part of the sliding seat; It also includes a reset assembly; the reset assembly includes a second slider slidably matched with the guide rail and a second fixing seat fixedly installed on the outer side wall of the first support frame; one end of the second slider is connected to the second fixing seat through a second compression spring, and the other end thereof is in conflict with the wedge structure of the second slider; The first fixed seat is also provided with two guide plates, which are respectively located on both sides of the sliding seat; The first rotating shaft is rotatably mounted on the first supporting frame via a first bearing, and locking blocks are provided at both ends of the first rotating shaft; the second rotating shaft is rotatably mounted on the second supporting frame via a second bearing, and locking blocks are provided at both ends of the second rotating shaft; the shape of the supporting portion is an "n" shape.
