[0005] As a further description of the above technical solution:

[0006] A clamping plate is fixedly connected to the top of the pull rod.

[0007] As a further description of the above technical solution:

[0008] One end of the pull rod 2 away from the limiting plate is fixedly connected with a handle.

[0009] As a further description of the above technical solution:

[0010] The width of the connecting column 4 corresponds to that of the connecting column 2.

[0011] As a further description of the above technical solution:

[0012] The connecting rod is fixedly connected with an external connecting piece.

[0013] As a further description of the above technical solution:

[0014] An end of the connecting column three away from the connecting column two is fixedly connected with an inner connecting piece, and the inner connecting piece is connected to the outer connecting piece.

[0015] As a further description of the above technical solution:

[0016] The connecting column 4 slides inside the sleeve.

[0017] The utility model has the following beneficial effects:

[0018] In the utility model, the card plate is pulled upward to pull up the pull rod 1 to drive the connecting column 4 to slide upward, and at the same time, the spring 2 is compressed so that the bottom of the connecting column 4 is pulled out from the connecting column 2. At the same time, the compressed spring 1 rebounds and pushes the connecting column 1 to move to the left, thereby driving the connecting column 3 and the inner connecting part to move to the left, making it easier to fasten the inner connecting part to the outer connecting part.
