The peripheral edge of the bottom surface of the box cover 3 is provided with a third semicircular recess 31 and a fourth semicircular recess 32. When the peripheral edge of the bottom surface of the box cover 3 is fixed on the peripheral edge of the top surface of the box seat 2, the first semicircular recess 22 and the third semicircular recess 31 can jointly form a first through hole for the first cable 4 to pass through and match the diameter of the first cable 4, and the second semicircular recess 23 and the fourth semicircular recess 32 can jointly form a second through hole for the second cable 5 to pass through and match the diameter of the second cable 5.

[0023] In the specific embodiment, the temperature controller body 1 can be first installed in the mounting groove 21 in the box seat 2, and then the first cable 4 and the second cable 5 can be respectively placed in the first semicircular recess 22 and the second semicircular recess 23, and the wires in the first cable 4 and the second cable 5 can be connected with the corresponding terminal 11 on the temperature controller body 1.
