The working principle and the using method of the master controller of the embodiment are as follows:

in the master controller provided by the present embodiment, the rotation shaft 2 includes the first rotation shaft 21 and the second rotation shaft 22, and the use of a plurality of rotation shafts 2 enables the master controller to be connected with more contact sockets 9 for more control;

and the first and second

rotary shafts

21 and 22 are each composed of a restoring block 3 and a shaft body, with the restoring block 3 as a part of the rotary shaft 2; the relative error generated by assembling the rotating shaft 2 and the reset block 3 as two independent components is avoided, and the relative displacement generated by the rotating shaft 2 and the reset block 3 as the two independent components in the movement process can be avoided, so that the stability of the master controller can be improved, and the rotating shaft 2 can better drive the reset block 3 to rotate;

the spring of the reset mechanism 6 can generate an elastic force on the reset block 3, so that clamping stagnation can be avoided in the process that the operating rod 1 is reset to the initial position, and the probability of clamping stagnation of the master controller can be reduced; moreover, because two ends of the reset block 3 are provided with two protrusions 31, the top block 64 at one end of the spring can have a larger moment arm when pushing a certain protrusion 31, and can generate a relatively larger moment under the condition of a certain elastic force, thereby further reducing the probability of jamming of the master controller; due to the existence of the sliding groove 62, the spring can be ensured to be bent in a smaller range, and the service life and the elasticity of the spring are further ensured; the top block 64 can be in better contact with the protrusions 31 at the two ends of the reset block 3, and the operating rod 1 is pushed to reset more stably.

When the device is used, a worker holds the handle cover 11 at the top end of the operating rod 1, so that the operating rod 1 moves along the axial direction of the first rotating shaft 21, at the moment, the second rotating shaft 22 drives the sector gear 5 to rotate, the sector gear 5 drives the cam shaft 7 to rotate, the cam shaft 7 drives the cam piece 81 to be in contact with the roller seat 8, and signals are transmitted to the contact seat 9; meanwhile, one protrusion 31 of the reset block 3 can rotate downwards along the sliding groove 62 of the reset mechanism 6, so that the top block 64 of the reset mechanism 6 compresses the spring downwards; when the operation is completed, the operator can manually reset the operating rod 1, or directly release the operating rod 1, and under the elastic force of the spring, the top block 64 moves upward, so as to push the protrusion 31 of the reset block 3 to move upward, so that the second rotating shaft 22 rotates until the operating rod 1 returns to the original position.

Similarly, when the operator moves the operation rod 1 along the axial direction of the second rotation shaft 22, the principle of generating the signal is the same as that when the operation rod 1 moves along the axial direction of the first rotation shaft 21, and the description thereof is omitted.

It should be noted that the module composed of the reset mechanism 6, the sector gear 5, the cam shaft 7, the contact base 9 and the roller base 8 used in cooperation with the first rotating shaft 21 and the module composed of the reset mechanism 6, the sector gear 5, the cam shaft 7, the contact base 9 and the roller base 8 used in cooperation with the second rotating shaft 22 are two mutually independent modules, and any one of the two modules can be independently replaced when damaged, so that the master controller can be conveniently maintained.
