[0055] By rotating the rotating seat 3, the telescopic rod 5 is telescopic, and the universal joint 6 is adjusted in multiple directions to adjust the insertion position and angle of the plug 7.

[0056] The universal joint 6 is a prior art structure, which is used in the present application and can be adjusted in multiple directions.

[0057] Please refer to Fig. 3 and Fig. 5 The adjusting assembly in the embodiment is further provided with an adjusting assembly for adjusting and connecting with the plug 7.

[0058] The adjusting assembly is connected with a plug 14 for plug-in connection with the plug 7.

[0059] It should be noted that the adjusting assembly includes a circular annular groove 11 formed in the surface of the rotating seat 3, a moving block 12 is rotatably arranged in the inner circumference of the annular groove 11, the moving block 12 is not separated from the annular groove 11, a steel wire rope 13 is fixedly arranged on the outside of the moving block 12, and the other end of the steel wire rope 13 is fixedly arranged with a plug 14 for plug-in connection with the plug 7.

[0060] The length of the steel wire rope 13 is designed to only support the multi-angle adjustment of the plug 14, and to ensure that the steel wire rope 13 is in a taut state after the overall connection.

[0061] The inner diameter of the plug 14 is equal to the diameter of the plug 7, so as to ensure the fitting degree of insertion, and the other end of the steel wire rope 13 is fixedly arranged with a rotating head, and the rotating head is rotatably arranged with the plug 14.

[0062] Please refer to Fig. 2 and 4 The plug 14 and the plug 7 in the embodiment are provided with a connecting locking member to ensure the connection limitation and anti-rotation loosening between the six hexagonal threaded heads 1 after threaded locking.

[0065] The working principle of the above embodiment is as follows:

[0066] In use, by butting the flange plate of the soot blower lifting valve with the connected flange plate, the threaded rod on the connected flange plate passes through the perforation on the flange plate of the soot blower lifting valve, then the handheld threaded head 4 is rotated and separated from the rotating seat 3, realizing the separation of the threaded head 4 and its connecting part from the overall hexagonal threaded head 1, so that the hexagonal threaded head 1 can be screwed onto the threaded rod on the flange plate by holding the hexagonal threaded head 1 and cooperating with the tightening tool, realizing the installation and locking of the soot blower lifting valve;

[0067] After the hexagonal threaded head 1 is screwed in one by one, by adjusting the rotation of the rotating seat 3 in the circular groove 2 to adjust the orientation, and by adjusting the extension length of the extension rod 5, and cooperating with the universal connector 6 to adjust the plug 7 in all directions, the insertion angle of the plug 7 is adjusted.

[0069] In addition, after the plug 7 is inserted into the socket 14, under the elastic extension and contraction of the extension spring 9, the locking head 10 on the extension spring 9 is inserted into the locking hole 15 on the socket 14, thereby realizing the locking and fixing of the insertion of the plug 7 and the socket 14. After the overall locking and fixing is completed, by holding the rotating tightening screw 16 and rotating it into close contact with the hexagonal threaded head 1, the rotating seat 3 is locked and fixed in the circular groove 2, thereby avoiding the self-rotation of multiple hexagonal threaded heads 1 after connection. By holding the application, the above scheme realizes the connection between the adjustment assembly and the adjustment assembly on the adjacent hexagonal threaded head 1 after the tightening of the hexagonal threaded heads 1 distributed on the flange plate, thereby realizing the mutual connection between the hexagonal threaded heads 1 on the flange plate, avoiding the rotation of a single hexagonal threaded head 1, and causing the tightening to be loose.

[0070] It should be noted that when the hexagonal threaded head 1 needs to be disassembled, the locking head 10 is separated from the locking hole 15 on the socket 14 by pressing, the extension spring 9 is compressed synchronously, and the locking head 10 is separated from the socket 14. Then, the threaded head 4 is separated from the rotating seat 3, and the hexagonal threaded head 1 is loosened and removed one by one by using a tool.
