[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A fire sprinkler head, such as Figures 1-4 As shown, it includes two connecting rods 1 and a section of thermal glass ball 2. The connecting rods 1 are located on both sides of the thermal glass ball 2. A sliding groove is opened on the side of the connecting rod 1 near the thermal glass ball 2. A connecting plate is slidably connected in the sliding groove. A first protective sleeve 3 is fixedly connected to the end of the connecting plate away from the connecting rod 1. The first protective sleeve 3 is located on one side of the thermal glass ball 2. A second protective sleeve 4 is detachably connected to one side of the first protective sleeve 3. The first protective sleeve 3 and the second protective sleeve 4 cover the thermal glass ball 2. A handle 10 is fixedly connected to the side of the second protective sleeve 4 away from the first protective sleeve 3.

[0019] Specifically, the bottom end of the connecting rod 1 is fixedly connected with a splash plate, the thermal glass ball 2 is located above the splash plate, the first protective sleeve 3 is integrally formed with the connecting plate, the two connecting plates are located on the two sides of the thermal glass ball 2 respectively, the connecting plate and the sliding groove are matched with each other to guide the movement of the first protective sleeve 3, the first protective sleeve 3 is first attached to one side of the thermal glass ball 2, then the second protective sleeve 4 is assembled to the first protective sleeve 3, the covering of the thermal glass ball 2 is completed, the thermal glass ball 2 is prevented from being knocked with the outside world, the triggering condition of the thermal glass ball 2 is ensured to meet the expectation, when the installation of the fire sprinkler head is completed, the second protective sleeve 4 is first disassembled, then the first protective sleeve 3 is disassembled, the anti-skid groove is formed in the side wall of the handle 10, and the disassembly of the second protective sleeve 4 is facilitated.
