Further, a threaded hole II246 is formed in a front side surface of the front mounting block 24, and the adjustment pin 318 is mounted in the threaded hole II 246.

In this embodiment, the setting of adjustment nail 318 and spring III319 gives the upper end of the regulating block 313 of L-shape with the effort, and the position of adjustment nail 318 matches each other with the position of nail 314 that resets, and the cooperation bulb plunger I312 gives the effort of mounting panel 21 of the below of regulating block 313, can make the holistic atress of shower nozzle installation device 2 more even when back-and-forth movement mounting panel 21, moves more steadily and smoothly. The provision of spring III319 prevents the adjustment pin 318 from being loosened from the threaded bore II 246.

Example 4:

on the basis of embodiment 2, bottom plate position control device is including installing on lifting frame 12 and being located mounting block II321 on mounting panel 21 front end right side, install ball plunger II322 that runs through its left and right sides face on the mounting block II321, ball plunger II 322's bulb portion butt in on mounting panel 21's the front end right flank, mounting panel 21's front end left surface has butt joint has side direction elasticity locating pin I324, side direction elasticity locating pin I324 install in lifting frame 12 is last, adjusting wheel 323 is installed to ball plunger II 322's right-hand member portion.

Furthermore, the right side surface of the rear end of the mounting plate 21 abuts against the cylindrical side surface of the cylindrical pin 325, the cylindrical pin 325 is mounted on the lifting frame 12, the left side surface of the rear end of the mounting plate 21 abuts against the lateral elastic positioning pin II326, and the lateral elastic positioning pin II326 is mounted on the lifting frame 12.

Furthermore, an adjusting pin 327 is disposed on the mounting plate 21, the position of the adjusting pin 327 matches with that of the cylindrical pin 325, and a cylindrical side surface of the cylindrical pin 325 abuts against the adjusting pin 327. The adjusting pin 327 is made of steel material and has wear-resistant characteristics.

In this embodiment, when the deflection angle of the bottom plate 22 is adjusted, the ball plunger II322 is screwed so that the length of the ball plunger II322 extending out of the mounting block II321 is extended or shortened, so that the front end of the mounting plate 21 moves left or right, the lateral elastic positioning pin I324 is mounted on the opposite side of the ball plunger II322, when the front end of the mounting plate 21 moves left or right, the lateral elastic positioning pin I324 always gives a reverse acting force to the mounting plate 21, which not only gives a space for the mounting plate 21 to move left or right, but also automatically compresses the mounting plate 21 reversely, so as to fix the position of the mounting plate 21. Lateral elastic positioning pins II326 and cylindrical pins 325 are respectively mounted on the left and right sides of the rear end of the mounting plate 21, and as shown in fig. 13, a stopper portion 3241 is provided at the upper end of the lateral elastic positioning pin I324, and the side surface of the mounting plate 21 and the stopper portion 3241 are in contact with each other. When the front end of the mounting plate 21 moves left and right, the mounting plate 21 rotates around the cylindrical pin 325, the lateral elastic positioning pin II326 on the opposite side of the cylindrical pin 325 keeps the rear end of the mounting plate 21 always pressed against the cylindrical pin 325, and the conical limiting part on the upper end of the mounting plate allows the mounting plate 21 to deflect left and right, thereby realizing the adjustment of the deflection position of the mounting plate 21. In addition, when the front and back positions of the mounting plate 21 are adjusted through the ball plunger I312, the ball plunger II322, the lateral elastic positioning pin I324, the cylindrical pin 325 and the lateral elastic positioning pin II326 can guide and limit the front and back movement of the mounting plate 21, so that the situation that the mounting plate 21 moves left and right when the front and back positions are adjusted is avoided, adjustment of different dimensions is not interfered with each other, and the position adjustment is more accurate. The setting of regulating wheel 323 is more convenient for control and revolves angle and the number of turns of twisting ball head plunger II322 to the beat angle of more accurate control mounting panel 21.

Further, the mounting block II321 and the lateral elastic positioning pin I324 are mounted on the front support beam 121, and the cylindrical pin 325 and the lateral elastic positioning pin II326 are mounted on the rear support beam 122.
