[0040] See also Figure 10-11 A spring column 905 is fixedly installed at the bottom of the button body 902, and the outer side of the spring column 905 is fitted with one end of the spring C906, and the other end of the spring C906 is installed on the bottom wall of the groove of the shell 901; a positioning platform 907 is fixedly installed on the side of the button body 902, and the positioning platform 907 corresponds to the positioning groove 800. When installed, the positioning platform 907 is inserted into the interior of the positioning groove 800.

[0041] Working principle: In the first embodiment, when in use, by pushing the bottom shell 200 to move up or down, the equally spaced limiting grooves 104 will squeeze the spherical clamping column 103, and the spring A102 will be passively compressed, and the base 100 and the bottom shell 200 will be unlocked relative to each other, thereby adjusting the position of the bottom shell 200; conversely, when the push on the bottom shell 200 is released, the spring A102 will push the spherical clamping column 103 into the corresponding limiting groove 104, and the base 100 and the bottom shell 200 will be locked, thereby locking the bottom shell 200 after the adjusted position;

[0042] In the second embodiment, when in use, by pushing the bottom shell 200 up or down, the toothed portion 108 will squeeze the toothed block 106, the spring B107 will be passively compressed, the base 100 and the bottom shell 200 will be unlocked relative to each other, and then the position of the bottom shell 200 will be adjusted; conversely, the push on the bottom shell 200 is released, the spring B107 pushes the toothed block 106 and the toothed portion 108 to engage with each other, thereby locking the base 100 and the bottom shell 200.

[0043] By squeezing the button body 902 through the pressing platform 903, the button body 902 shrinks into the shell 901, and the spring C906 is compressed, the buckle 904 will be separated from the card hole 700, and then the base 100 and the connecting seat 900 are disassembled. Conversely, the connecting groove 600 on the surface of the base 100 is aligned with the connecting seat 900 and inserted, and the buckle 904 will abut against the card hole 700, thereby realizing the installation of the base 100 and the connecting seat 900.
