[0037] By setting two limit brackets 10, a split structure is formed, the limit bracket 10 limits the temperature controller 100, and the locking piece 20 locks the limit bracket 10 to facilitate installation and disassembly; the mounting hole 11 of at least one limit bracket 10 is a long hole, and the long hole extends along the first straight line direction, so that the distance between the two limit brackets 10 along the first straight line direction can be adjusted to adapt to thermostats 100 of different sizes, which not only reduces the cost, but also improves the assembly efficiency, and can also ensure the stability of the installation of the thermostat 100 to achieve reliable temperature control.

[0038] Typically, the thermostat 100 includes a thermostat body 110 and a fixing bracket 120.

In this embodiment, the limiting bracket 10 presses against the fixing bracket 120, and a structure that cooperates with the limiting bracket 10 is conveniently provided on the fixing bracket 120.

[0039] In the present embodiment, the mounting holes 11 on each limiting bracket 10 are all long holes, which increases the adjustable range. In the present embodiment, the locking member 20 includes a bolt, and locking can be achieved by setting a mounting hole 11 on each limiting bracket 10. The locking member 20 also includes a gasket, which is arranged between the bolt and the limiting bracket 10. In some embodiments, the locking member 20 can also be a buckle. In some embodiments, two or more mounting holes 11 can be arranged on each limiting bracket 10 to make the locking more stable. In some embodiments, the locking member 20 can be locked by bonding.
