DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following will further illustrate the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0016] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

In order to improve the stability of the supporting mechanism 3, in the present utility model, a PVC pipe 31 for passing through the steel bar support 1 is arranged in the through hole, and a threaded rod 32 is arranged in the PVC pipe 31. After pouring the cement, the PVC pipe 31 protects the threaded rod 32 from contacting the cement, which facilitates the extraction of the threaded rod 32. Both ends of the threaded rod 32 are respectively connected with a supporting mechanism 3. The supporting mechanism 3 includes a support base 39 pressed on the ground. The support base 39 is provided with a socket, and a fixing pin 4 for inserting into the ground is inserted in the socket.
