[0048] The rest of the structure is the same as that of example 2.

[0049] The working principle of the application:

[0050] First step, first of all, the controller body 1 is placed on the installation rack, and by unscrewing the long rod screw 23, the rotating seat 3 can rotate relative to the blocking seat 2, and then drive the corresponding gear 32 to rotate, so as to mesh and drive the corresponding rack 33, L-shaped bending rod 34 and extrusion strip 35 to slide, until the extrusion strip 35 is retracted from the corresponding contraction cavity, and does not extrude the corresponding storage cavity 12 inner wall, at this time the blocking seat 2 can be linearly moved through the limiting sliding relationship between the limiting sliding block 21 and the limiting sliding groove 14, thereby driving the entire rotating seat 3 including the mounting seat 4 to move, the mounting screw 42 will also slide synchronously during the movement of the mounting seat 4, and the mounting screw 42 can adjust the final installation angle with the rotation of the rotating seat 3, and since the mounting screw 42 is arranged through the strip-shaped hole 41, the model specification of the mounting screw 42 can be replaced to facilitate the adaptation to the threaded hole on the installation rack, in addition, the mounting screw 42 can also slide in the strip-shaped hole 41, thereby facilitating the alignment of the mounting screw 42 with the threaded hole on the installation rack, and finally completing the threaded assembly, and the adaptability of the controller body 1 is completed through the multi-point fixing around the controller body 1.

[0051] Second step, since the two blocking seats 2 are moved away in the storage cavity 12, the exhaust port 13 is normally exposed, when the controller body 1 is connected with other sensors, displays and the like through the cable connector 11 to form an input / output terminal connection, and starts to work normally, the cooling fan in the controller body 1 is started synchronously, the heat generated by the electronic elements in the controller body 1 is discharged from the exhaust port 13 through the cooling fan, so that the pressure in the controller body 1 is reduced, and the air with relatively low temperature from the outside is replenished through the air inlet 15, forming a circulating cooling system.

[0052] Third step, when the controller body 1 needs to be disassembled, first of all, the mounting screw 42 is threadedly disengaged from the installation rack, and then the long rod screw 23 is unscrewed, so that the rotating seat 3 can rotate relative to the blocking seat 2, thereby completely storing the mounting seat 4 including the mounting screw 42 in the storage cavity 12, and when the mounting seat 4 is completely stored in the storage cavity 12, and the roller 43 contacts the inner wall of the storage cavity 12, the extrusion strip 35 just extends from the expansion cavity and abuts against the inner wall of the storage cavity 12, thereby completing the limiting fixation between the blocking seat 2 and the controller body 1, avoiding the free sliding of the blocking seat 2 during the movement of the controller body 1, causing the exposure of the exhaust port 13 and the entry of dust and impurities into the electronic elements.

[0053] The above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalent features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present application.
