[0019] Embodiment 1

[0020] See also Figure 1 and Figure 2 The simple locking device provided by the utility model includes a base 3, a sleeve 1 and a locking member 2. The sleeve 1 is arranged on the base 3, and the locking member 2 is connected to the sleeve 1, and is used to lock the railing 4 and the sleeve 1 when the railing 4 is inserted into the sleeve 1.

[0021] It can be known that the sleeve 1 can be welded to the base 3, and it can be a full-weld method. The sleeve 1 can be vertically set on the base 3. The sleeve 1 can be cylindrical, and the railing 4 can also be correspondingly cylindrical, and the outer diameter of the railing 4 is smaller than the inner diameter of the sleeve 1. The railing 4 is inserted into the sleeve 1, and then the locking piece 2 locks the railing 4 in the sleeve 1. The base 3 is fixed at a preset position, and the preset position can be the ground, thereby achieving the fixation of the railing 4.

[0022] See also Figure 1 In some embodiments, the sleeve 1 includes a main body 101 and a protrusion 102. The main body 101 is provided with a plug-in cavity for inserting the railing 4. The protrusion 102 is arranged on the outer wall of the main body 101. The protrusion 102 is provided with a first threaded hole connected to the plug-in cavity. The locking member 2 is threadedly connected in the first threaded hole and inserted into the sleeve 1. The end of the locking member 2 inserted into the sleeve 1 abuts against the railing 4 to lock the railing 4. The base 3 is connected to the main body 101 by full welding.
