The threads at both ends of the adjusting rod 12 have opposite rotation directions. The first slider 1 5 and the first mounting plate 16 are both connected to the mounting frame 11 in a sliding manner. A fixing frame 2 is fixed on the top of the first mounting mechanism 1. The annulator body 3 is installed between the first mounting mechanism 1 and the fixing frame 2. Terminals 4 are installed on both sides of the annulator body 3. The terminal posts 4 penetrate the fixing frame 2. A driving mechanism 5 is installed on the top of the fixing frame 2. The driving mechanism 5 penetrates the fixing frame 2. Geothermal mounting mechanisms 6 are installed on both sides of the driving mechanism 5. The first mounting mechanism 1 and the second mounting mechanism 6 are used for mounting the device on the equipment. The driving mechanism 5 includes a fixed The housing 51 has a rotating shaft 52 and a worm 55 connected thereto in rotation. A worm wheel 53 is fixedly sleeved on the rotating shaft 52. The rotating shaft 52 passes through the fixed frame 2 and is connected to the connecting frame 54. The worm 55 passes through the side of the housing 51 and is connected to the second knob 56. The worm wheel 53 and the worm 55 are meshing transmission. Two second mounting mechanisms 6 are fixed to the side of the connecting frame 54.
