A locator 4 for fixing the locating pin 1 at the end of the vertical bracket 3 is installed on one side.

The positioner 4 includes a cylindrical stopper 401, which is perpendicular to the vertical bracket 3 and is limitedly connected thereto. When the stopper 401 is relatively fixedly connected to the vertical bracket 3, the frame is rectangular; when the stopper 401 and the vertical bracket 3 are released from the clamping and relatively rotating connection, the frame can be deformed into a parallelogram; the front side of the stopper 401 is fixedly connected to a front bar 402, and the rear side is fixedly connected to a rear bar 403. The rear bar 403 is rotatably connected to a stopper rod 405 parallel to the vertical bracket 3 through a connecting pin 404. The tail end of the stopper rod 405 is used to fix the positioning pin 1 when it is clamped, and the fixing of the positioning pin 1 is released when the clamping is released. By setting the front bar 402, the clamping can be released when the front bar 402 is rotated, and the operation is convenient.

As a preferred solution, the limiting rod 405 includes a first limiting rod 40501 and a second limiting rod 40502 with tail ends facing opposite directions;

The first limiting rod 40501 and the second limiting rod 40502 act on the positioning pins 1 at both ends of the vertical bracket 3 connected to the positioner 4 respectively to fix the positioning pins 1 at both ends of the vertical bracket 3. The frame is rectangular and has a stable structure.

A threaded rod is provided at the center of the bottom surface of the stopper 401, and a threaded groove matching the threaded rod is provided on the side wall of the vertical bracket 3. When the threaded rod and the threaded groove are fastened together, the stopper 4 and the vertical bracket 3 are relatively fixedly connected, and the tail end of the stopper rod 405 is clamped with the positioning pin 1, and the frame is a stable rectangle;
