[0036] A second extension ear 21 is fixedly connected to the lower part of the vertical rod 15 corresponding to the insertion rod 8, and a second wedge block 22 is fixedly connected to the top surface of the second extension ear 21. A second extrusion groove 23 is opened on the insertion rod 8 corresponding to the second wedge block 22. The second wedge block 22 corresponds to and fits with the second extrusion groove 23, and the second extension ear 21 and the second wedge block 22 both fit and move with the inner wall of the installation cavity 14.

[0039] By moving the vertical rod 15 upward, the first wedge block 19 can be separated from the first extrusion groove 20, and at the same time, the second wedge block 22 can be driven to insert into the second extrusion groove 23, so that the insertion rod 8 is pushed by the extrusion thrust of the second wedge block 22 and the second extrusion groove 23, so that the insertion rod 8 shrinks into the movable cavity 7, thereby releasing the restriction and facilitating the separation of the V-shaped block 5 from the connecting seat 2. Example

[0040] See also Figure 6 In an embodiment of the utility model, a mounting structure of a thermal control instrument for a thermal power plant is provided, and a back surface of a mounting plate 1 is fixedly connected with a back adhesive 28 .

[0041] The mounting plate 1 can be directly adhered to the fixing surface by means of the adhesive 28 . The mounting plate 1 is installed and fixed by means of the fixing holes at the four corners in combination with the expansion screws. The double installation effect makes the installation of the mounting plate 1 more convenient.

[0042] The working principle of the utility model is:

During the insertion of the V-shaped block 5, the inclined surface of the V-shaped groove 3 guides the V-shaped block 5 to the center, and at the same time, when the V-shaped block 5 is inserted During the process, the slope 11 at the end of the insertion rod 8 is squeezed by the edge, so that the insertion rod 8 squeezes the first spring 9 to contract, so that the V-shaped block 5 can be inserted. When the insertion rod 8 corresponds to the socket 10, the insertion rod 8 pops out from the left and right lower parts of the first spring 9 and is inserted into the socket 10 to form a limit, and then the connecting cross bar 24 is released. At this time, under the action of the second spring 17, the vertical rod 15 moves downward, so that the first wedge block 19 is inserted into the first extrusion groove 20 to limit the insertion rod 8, and the limiting ear 25 is further rotated to overlap with the bottom surface of the mounting plate 1, thereby limiting the connecting cross bar 24 to prevent the vertical rod 15 from moving upward and causing the insertion rod 8 to loosen.
