An anti-skid layer is connected to the inner wall of the arc rod. The arc rod cooperates with the fire sprinkler frame to increase the contact area between the clamping rod and the fire sprinkler frame. The anti-skid layer is provided to increase the friction coefficient between the arc rod and the fire sprinkler frame, thereby achieving stable clamping of the clamping rod and the fire sprinkler frame.

[0007] Furthermore, the lifting assembly includes a transfer rod rotatably connected to the bottom end of the driving rod, the transfer rod is slidably connected to the through hole, the bottom end of the transfer rod is connected with a threaded groove, the threaded groove is provided with a threaded rod through a threaded connection, the threaded rod is rotatably connected to the shell and the other end passes through the through hole and is connected to a first driving handle at the end, the first driving handle is rotatably connected to the shell, and the first driving handle drives the threaded rod by rotating the first driving handle, the threaded rod drives the transfer rod to slide along the through hole by cooperating with the thread of the thread groove, and the transfer rod drives the driving rod up and down.

[0010] The advantages of the utility model compared with the prior art are:

[0011] 1. The setting of the lifting assembly facilitates the driving rod to be driven up and down along the housing. When the driving rod is downward, the clamping rod overcomes the elastic force of the elastic member under the cooperation of the limit ring so that its free end contracts inward, thereby clamping the fire sprinkler frame; when the driving rod is upward, the limit ring no longer meets the limit requirements of the clamping rod, and the clamping rod expands outward under the action of the elastic member, thereby releasing the clamping limit of the fire sprinkler frame;

[0012] 2. The setting of the rotating assembly facilitates the driving rod to rotate, and the driving rod drives the fire sprinkler frame to rotate through the clamping rod, thereby completing the threaded connection between the fire sprinkler frame and the high-pressure water pipe.
