5. The handle rotating body and the knob driving part are synchronously rotated and connected through the meshing fit of the internal spline and the external spline, meanwhile, the internal spline can axially move along the external spline, and the internal spline also correspondingly axially moves along the external spline when the adjusting rod extends out of the axial length of the adjusting sleeve so as to abdicate the adjusting length of the adjusting rod.

6. The length of the outer spline is larger than or equal to the adjustable maximum axial length of the adjusting rod, so that the adjustable maximum axial length of the adjusting rod is ensured to have enough abdicating space.

7. The screw sleeve part is in screw connection fit with the valve body, and the bottom end of the pressing part is pressed against the decorative panel, so that the seamless fit between the decorative panel and the handle shell can be realized.

8. The limiting nut is screwed on the periphery of the bottom end of the handle rotating body and abuts against the bottom end of the inner ring sleeve, so that the handle rotating body can rotate in the inner ring sleeve and cannot be separated from the inner ring sleeve.

9. The length of the screw sleeve part corresponding to the internal thread of the screw sleeve part is larger than or equal to the adjustable maximum axial length of the adjusting rod, so that the adjustable maximum axial length of the adjusting rod is ensured to have enough abdicating space.

10. An anti-slip ring is arranged between the adjusting sleeve and the adjusting rod, so that the relative rotation between the adjusting sleeve and the adjusting rod can be avoided after the shower faucet is installed.

11. When the button is not matched with the adjusting sleeve, the adjusting sleeve can be connected with the handle rotating body through the adjusting plug, the bottom end of the adjusting plug presses the adjusting sleeve downwards until a first limiting block close to the button abuts against the limiting table, the adjusting plug can continuously press the adjusting sleeve, manual pressing is not needed, and labor is saved; after the regulation of adjusting the pole is accomplished, can demolish adjusting the end cap, again with the button with adjust the cover assemble can, it is more convenient to install.
