[0056] During specific use, the locking limit piece 208 is locked and assembled in the locking assembly plate 202, the valve core 204 is assembled in the locking limit piece 208, and the bottom plate 206 is assembled on one side of the locking assembly plate 202 by plugging and matching the assembly pin 210 with the plug groove 211, and the limiting protrusion 212 with the avoidance hole. When the door handle 1 needs to be rotationally locked, a pair of locking balls 205 are arranged between the engaging groove and the locking groove between the locking sleeve 203 and the valve core 204. Subsequently, the assembly cover plate 201 and the door handle 1 are assembled on the other side of the locking assembly plate 202 by means of the mutual engagement of the engaging convex ring 207 and the assembly avoidance groove on the locking assembly plate 202 and the mutual cooperation of the linkage plug-in column 209 and the rotation limit groove, thereby completing the assembly process of the door handle. In addition, the locking ball 205 can be arranged between the locking sleeve 203 and the valve core 204 so that the valve core 204 cannot rotate in the locking sleeve 203, thereby rotationally locking the door handle 1.

[0057] When the rotation locking state of the door handle 1 needs to be released, the locking assembly plate 202 and the assembly cover plate 201 are disassembled and separated by applying force to the disassembly avoidance grooves on the upper and lower sides of the locking assembly plate 202. Subsequently, a pair of locking balls 205 are placed in the storage avoidance grooves above the engaging protruding ring 207. After being placed, the locking assembly plate 202 and the assembly cover plate 201 can be re-engaged. The rotation locking state of the door handle 1 is released by adjusting the locking ball 205 away from between the locking sleeve 203 and the valve core 204, so that the door handle 1 can rotate freely.
