[0038] Reference Figure 3-Figure 5 The outer wall of the extrusion block 206 is plugged into the inner wall of the extrusion groove 209. The plugging of the two can make the movable block 201 in a fixed state. The bottom end of the movable block 201 contacts the top end of the extrusion block 206. The vertical movement of the movable block 201 can drive the horizontal movement of the extrusion block 206. The bottom end of the foot pedal 204 contacts the top end of the connecting block 207. The contact between the two can make the connecting block 207 have a certain supporting effect on the foot pedal 204 in the open state.

[0039] Reference Figure 6-Figure 7 One end of the limit spring 703 is fixedly connected to the inner wall of the fixed column 702, and the other end of the limit spring 703 is fixedly connected to the outer wall of the plug-in column 701. The outer wall of the plug-in column 701 is slidably connected to the inner wall of the fixed column 702. The elasticity of the limit spring 703 makes the plug-in column 701 have the reset and limiting functions. The outer wall of the connecting column 704 is plugged into the inner wall of the connecting groove 705, and the outer wall of the connecting column 704 is plugged into the inner wall of the guide block 6. The plug-in can fix the handle 5.

[0040] Working principle: When the relevant personnel need to fix the roller walker, they first press the top of the movable block 201 downward with the sole of the foot. When the top of the movable block 201 is squeezed, it will move downward, and the bottom end of the movable block 201 will squeeze the inclined surface of the squeezing block 206. At this time, the squeezing block 206 will move toward the end of the connecting spring 208 and squeeze the connecting spring 208, and the connecting plate 202 will squeeze the elastic telescopic rod 205. When the movable block 201 moves to a certain position (that is, the bottom end of the movable block 201 contacts the bottom end of the inner wall of the bottom plate 1), the anti-slip plate 203 contacts the ground. At the same time, due to the elasticity of the connecting spring 208, the squeezing block 206 is plugged into the squeezing groove 209, thereby completing the plug-in fixation of the connecting plate 202. At this time, the fixing device of the universal wheel is pressed again to increase the contact area between the anti-slip plate 203 and the ground, thereby increasing the overall stability of the device.

[0041] When the roller walker is in use, the foot pedal 204 can be pressed by the foot to move the foot pedal 204 downward. At this time, the bottom end of the foot pedal 204 squeezes the top inclined surface of the connecting block 207, so that the connecting block 207 drives the squeezing block 206 to move toward the end of the connecting spring 208. At this time, due to the elasticity of the elastic telescopic rod 205, the connecting plate 202 is reset, and the anti-slip plate 203 does not contact the ground, which does not affect the movement of the roller walker.

[0042] When the position of the handle 5 needs to be adjusted, first move the plug-in column 701 so that the plug-in column 701 drives the connecting column 704 to move, and then the connecting column 704 will disengage from the connecting groove 705 to release the limit, and then the handle 5 can be moved upward or downward until the position of the handle 5 is adjusted to suit the user and then the plug-in column 701 is released. At this time, due to the elasticity of the limit spring 703, the connecting column 704 is reset to complete the connection with the connecting groove 705. The operation is simple and convenient, and it can be better used by people of different heights.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
