6. A high precision mountable and demountable potentiometer according to any of claims 1, 2, 4 or 5, wherein: the inner wall of the shell (1) is provided with a thrust mechanism for providing vertical upward elastic thrust for the potentiometer shell (3).
7. A high precision mountable and demountable potentiometer according to claim 6, wherein: thrust mechanism is including removing post (27), the inner wall of casing (1) is seted up and is used for remove post (27) vertical gliding through-hole four, the last fixed surface of removing post (27) is connected with supports piece (28), the surface cover of removing post (27) is equipped with spring (29), the both ends of spring (29) respectively with support the lower surface of piece (28) with the inner wall fixed connection of casing (1).
8. The use method of the high-precision mountable and dismountable potentiometer according to claim 1, is characterized by comprising the following steps:
s1: when the potentiometer shell (3) is installed, the external spline groove (10) is inserted into the internal spline groove (11);
s2: then, the end parts of the two guide plates (5) are driven to abut against the side surface of the potentiometer shell (3) through the operation of the driving mechanism, so that the potentiometer shell (3) is preliminarily fixed;
s3: in the step S2, the pressing block (9) is driven to rotate and move downward under the action of the transmission mechanism, and the pressing block (9) rotates and moves downward, so that the pressing block (9) rotates above the potentiometer housing (3), and then presses the potentiometer housing (3) downward along with the downward movement of the pressing block (9), thereby compressing and fixing the upper surface of the potentiometer housing (3).
