By forming the groove 2013, the knob 2002 can be limited. By clamping the clamping block 2014 with the groove 2013, the knob 2002 can be conveniently limited.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1 - Figure 5, a sleeve 2009 is rotatably connected to the center of the limit groove 2016. A screw rod 2008 is threadedly connected to the bottom end of the sleeve 2009. A frustum block 2007 is slidably installed at the upper end inside the positioning block 2004. The bottom end of the screw rod 2008 penetrates through the positioning block 2004 and extends to the inside, and is connected to the top end of the frustum block 2007. A cavity 2010 is formed inside the knob 2002. The top end of the sleeve 2009 extends into the cavity 2010. The two sides of the sleeve 2009 are respectively slidably connected to the inner side walls of the cavity 2010. A spring 2011 is installed at the top end of the cavity 2010. The bottom end of the spring 2011 is connected to the top end of the sleeve 2009. By threadedly connecting the screw rod 2008 to the bottom end of the sleeve 2009, when the sleeve 2009 rotates, the frustum block 2007 can be driven to move by the screw rod 2008. By slidably installing the frustum block 2007, when it descends, the inner side wall of the ball 2005 can be extruded, so that it extends out of the through hole and fixes the mounting sleeve 1003. When the frustum block 2007 rises, the extrusion on the ball 2005 is released, so that the ball 2005 can enter the inside of the positioning block 2004, thus facilitating the separation of the rod head 2001 from the rod body 1001. By forming the cavity 2010 and slidably connecting the two sides of the sleeve 2009 to the inner side walls of the cavity, the knob 2002 can drive the sleeve 2009 to rotate, and the sleeve 2009 can also slide up and down inside the cavity 2010. By installing the spring 2011, when the user pulls up the knob 2002 and rotates it, it can be reset under the pulling force of the spring 2011.

[0034] Specifically, the working principle of the joystick that facilitates the replacement of the joystick head: When in use, pull the knob 2002 upward so that the bottom end block 2014 thereof is separated from the groove 2013 on the inner side wall of the limit groove 2016. At this time, rotate the knob 2002 to drive the sleeve 2009 to rotate, and then drive the frustum block 2007 to rise by means of the screw 2008 threadedly connected to its bottom end. When the frustum block 2007 rises, the ball 2005 loses the extrusion of the frustum block 2007 and is pressed into the positioning block 2004. At this time, the user inserts the end of the rod body 1001 equipped with the limit strip 1002 into the slot 2003. The limit strip 1002 is slidably connected to the positioning groove 2015 opened on the inner side wall of the slot 2003, so as to prevent the rod body 1001 from rotating. As the rod body 1001 is inserted, the mounting sleeve 1003 installed at its top end also sleeved on the outside of the positioning block 2004. At this time, the user pulls out the knob 2002 from the limit groove 2016 again and rotates the knob 2002 in the reverse direction to drive the sleeve 2009 to rotate, and then the screw 2008 drives the frustum block 2007 to descend. After the ball 2005 is extruded by the frustum block 2007, it moves outward of the through hole and is engaged with the card slot 1004 opened on the inner side wall of the mounting sleeve 1003, thus completing the fixation between the rod body 1001 and the rod head 2001. After the fixation is completed, the user releases the knob 2002, and the knob 2002 resets under the elastic force of the spring 2011, and the outer block 2014 thereof is re-engaged with the groove 2013. The knob 2002 will not rotate during use and affect the firmness between the rod body 1001 and the rod head 2001. By setting the internal thread of the sleeve 2008, when the sleeve 2008 rotates 90 degrees, 180 degrees, 270 degrees and 360 degrees, the screw 2008 drives the frustum block 2007 to descend to the lowest point or rise to the highest point inside the positioning block 2004, so as to realize the extrusion or release of the ball 2005, so as to adapt to the number of turns of the sleeve 2009 when the block 2014 is engaged with different grooves 2013.
