[0029] Example 2

[0030] The present embodiment is different from the embodiment 1 in that the adsorption fixing assembly 5 comprises a fixing screw 51, a fixing screw barrel 52 and a suction cup 53. A plurality of fixing screws 51 are connected to the lower part of the main body 1. The fixing screw barrel 52 is connected to the outer wall of the fixing screw 51. The suction cup 53 is connected to the end of the fixing screw barrel 52 away from the fixing screw 51.

[0031] Specifically, a limiting ring 54 is connected to the outer wall of one end of the fixing screw rod 51 close to the fixing screw barrel 52.

[0032] By adopting the above technical solution, in the process of rotating and moving the fixed screw 51 downward along the fixed screw barrel 52 , when the fixed screw barrel 52 moves to fit the limit ring 54 , the fixed screw barrel 52 is blocked and stops moving, thereby preventing the fixed screw barrel 52 from detaching from the fixed screw 51 .

[0033] Specifically, one end of the fixed screw barrel 52 away from the suction cup 53 is connected to a rotating ring, and an anti-slip pad is sleeved on the outer wall of the rotating ring.

[0034] By adopting the above technical solution, when it is necessary to rotate the fixed screw barrel 52, the operator holds the rotating ring and applies force to drive the fixed screw barrel 52 to rotate, which is convenient for the operator to operate. At the same time, during the operation, under the action of the anti-slip pad, the operator's hands can be prevented from slipping when applying force to rotate the rotating ring.

[0035] When this embodiment is used, the main body 1 is placed at the place of use, and the input port 2 on the main body 1 and the output ports 4 at both ends of the main body 1 are respectively connected to other devices using the connecting flange 3. The operator then holds the rotating ring and applies force to drive the fixed screw barrel 52 to rotate, so that the fixed screw barrel 52 rotates and moves along the fixed screw rod 51. The fixed screw barrel 52 rotates and moves downward, driving the suction cup 53 to rotate and move downward. When the suction cup 53 moves to fit the surface of the place of use, the rotating ring is stopped. Under the action of the suction cup 53, the main body 1 can be adsorbed and fixed, thereby ensuring the stability of the placement of the main body 1, and then ensuring the stability of the connection between the main body 1 and other devices.

[0036] The structure and principle of the adjustable paddle mechanism 6 composed of a paddle and a pin in the utility model have been disclosed in a paddle-type adjustable power divider disclosed in Chinese patent application No. 202321326720.8. Its working principle is: a paddle is arranged at a position opposite to the input port 2 in the main body 1, and the paddle is made of ceramic material. The paddle is rotatably connected to the side wall of the main body 1 through the pin. The paddle takes the pin as the axis and the width center section of the input port 2 as the symmetry plane. It can deflect within a range of 20 degrees to the left and right. When the paddle is turned, the paddle is rotated to the left and right. When the deflection angle of the paddle is 0 degrees, the entire power divider is symmetrical with the width center section of the input port as the symmetry plane. At this time, the microwave power enters from the input port 2 and is output from the output ports 4 at both ends in a state of equal power division, that is, the two output ports 4 each have 50% of the power. When the paddle is deflected toward one of the output ports 4, the microwave power entering from the input port 2 is output from the output ports 4 at both ends in an unequal state, and the output power of the output port 4 to which the paddle is deflected is greater than the output power of the other output port 4, and vice versa.

[0037] The structure and principle of the driving mechanism 8 composed of a motor and a reducer in the utility model have been disclosed in a paddle-type adjustable power divider disclosed in Chinese patent application No. 202321326720.8, and its working principle is: a motor is connected to the side wall of the main body 1, and a reducer is connected to the output end of the motor, and the reducer is connected to the rotating rod 71 component in the observation assembly 7. When in use, the motor is started, and with the cooperation of the motor and the reducer, the rotating rod 71 can be driven to rotate, thereby driving the adjustable paddle mechanism 6 to perform rotation and adjustment operations.

[0038] The working principle and use process of the utility model are as follows: the utility model places the main body 1 at the use site, and connects the input port 2 on the main body 1 and the output ports 4 at both ends of the main body 1 to other devices respectively through the connecting flange 3. The operator then holds the rotating ring and applies force to drive the fixed screw barrel 52 to rotate, so that the fixed screw barrel 52 rotates and moves along the fixed screw rod 51, and the fixed screw barrel 52 rotates and moves downward to drive the suction cup 53 to rotate and move downward. When the suction cup 53 moves to fit the surface of the use site, the rotating ring is stopped. Under the action of the suction cup 53, the main body 1 can be adsorbed and fixed to ensure the stability of the placement of the main body 1, and then the stability of the connection between the main body 1 and other devices can be ensured. In the subsequent use process, the operator needs to adjust the adjustable paddle mechanism 6 to adjust the output signals of the two output ports 4 When the pointer 74 is rotated, the operator can first observe the value on the scale disk 76 at the corresponding position of the pointer 74 through the mounting member 75, so as to facilitate the operator to determine the initial position of the adjustable paddle mechanism 6, and then use the driving mechanism 8 to drive the rotating rod 71 to rotate, the rotating rod 71 rotates to drive the external ring 72 and the adjustable paddle mechanism 6 to rotate, the external ring 72 rotates to drive the connecting rod 73 to rotate, and the connecting rod 73 rotates to drive the pointer 74 to rotate. During the rotation of the pointer 74, the operator can observe the values ​​on the scale disk 76 corresponding to the initial position of the pointer 74 and the scale disk 76 corresponding to the stop position of the pointer 74 through the mounting member 75, and judge the rotation angle of the pointer 74 by the difference between the two values, and then judge the rotation angle of the adjustable paddle mechanism 6, so that the operator can adjust the position of the adjustable paddle mechanism 6.
