Based on the use of different transformers, their overall sizes are different. Therefore, if the clamp is difficult to adjust during work, it is easy to directly affect the stability of the transformer after support. Utility Model Content

[0014] (1) The threaded rod and the guide rod are respectively installed at the front and rear positions in the support frame, and then the blocking baffle is installed inside the support frame to separate and protect the guide rod and the threaded rod. The transformer is installed between the two blocking baffles in the support frame. After the servo motor is started, the threaded rod is driven to rotate, and then the threaded rod and the threaded block cooperate with each other to move. Then, the insertion block is used to pass through the reserved groove, and the front and rear insertion blocks are used to complete the connection and installation of the side clamping plate. Therefore, the two side clamping plates are moved closer or farther along the threaded rod to form a clamping adjustment work. In this way, the two side clamping plates can clamp and position the two sides of the transformer.

In this way, the overall clamping adjustment ability is better improved during the work process;

[0015] (2) By inserting the buffer column into the fixing seat, and installing the fixing column at the bottom of the fixing seat, the buffer pad is first used to contact the supporting bottom plate to form a bottom cushion protection when working, and the fixing column moves inside the buffer groove when the buffer spring is compressed, and the protective pad contacts with the fixing column to form a buffer protection, thereby improving the overall buffer protection capability during the working process;

[0016] (3) The connection and installation of the fixing plate are completed by using the connecting column, and then the electric telescopic rod is installed on the end face of the fixing plate. When the left and right sides of the transformer are stable, the electric telescopic rod is started to drive the main clamping plate to move, so that the two main clamping plates are close to the front and rear positions of the transformer for clamping and fixing, thereby improving the overall stability during the working process.
