[0049] Specifically, the support plate 21 is a steel plate structure, the connecting portion 22 is a square tube structure welded on the support plate 21, and the external size of the connecting portion 22 is less than or equal to the internal size of the fixed support 10, so that the fixed support 10 can be sleeved on the connecting portion 22, and in the embodiment, the external size of the connecting portion 22 is equal to the internal size of the fixed support 10.

[0050] As a preferred embodiment in the embodiment, the fixed support 10 is further provided with a socket 11, the mouth size of the socket 11 is greater than or equal to the external contour size of the connecting portion 22, and when the connecting portion 22 is accommodated in the socket 11, the floor area of the auxiliary tooling is reduced.

[0051] Preferably, the support plate 21 is further welded with a reinforcing rib 23, the reinforcing rib 23 is used for strengthening the strength of the support plate 21, and the reinforcing rib 23 is located on both sides of the fixed support 10 when the support plate 21 is connected with the fixed support 10.

[0052] It should be noted that in the present embodiment, the fixed support 10 and the horizontal support 20 can also be fixedly connected, for example, the horizontal support 20 is a square tube structure, and the fixed support 10 and the horizontal support 20 are fixedly connected by welding. However, in this embodiment, the auxiliary tool is not convenient to store, and thus is not a preferred embodiment.

[0053] As a preferred embodiment in the present embodiment, the locking mechanism 40 is a bolt, the fixed support 10 is provided with a locking hole 12, and the locking mechanism 40 and the locking hole 12 are connected by threads.
