[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-3 The utility model provides an embodiment of a maza stool which is convenient for replacing seat cushions, comprising a maza stool body 1, the top surface of the maza stool body 1 is fixedly connected to a fixing frame 2, a fixing block 3 is fixedly connected to the middle part of the fixing frame 2, a threaded rod 4 is rotatably connected to the middle part of the fixing block 3, a movable block 5 is threadedly connected to the threaded rod 4, both sides of the movable block 5 are fixedly connected to a connecting piece 6, a transmission rod 7 is rotatably connected to the connecting piece 6, and the transmission rod 7 is rotatably connected to a connecting piece 2 8 on the side away from the connecting piece 6, an extension plate 9 is fixedly connected to the connecting piece 2 8, the extension plate 9 is slidably connected to the fixing frame 2, one side of the extension plate 9 is fixedly connected to a fixing plate 10, a sliding rod 11 is slidably connected to the top of the fixing plate 10, one end of the sliding rod 11 is fixedly connected to a limiting rod 14, and the other end of the sliding rod 11 is fixedly connected to a pull rod 15, and a spring 12 is sleeved on the sliding rod 11 between the fixing plate 10 and the limiting rod 14.

[0026] A rubber pad 16 is fixedly connected to the top surface of the fixing frame 2, and a seat cushion body 17 is connected to the top of the rubber pad 16. Two groups of threads are symmetrically arranged on the threaded rod 4, and two groups of movable blocks 5 are symmetrically arranged. A placement groove 18 is provided on the bottom surface of the stool body 1, and a support leg 19 is hinged in the placement groove 18. The bottom surface of the limiting rod 14 contacts the top surfaces on both sides of the seat cushion body 17, thereby enhancing the friction force on the seat cushion body 17 and improving the stability of the seat cushion body 17. One end of the threaded rod 4 passes through one side of the fixing frame 2 and is fixedly connected to the adjusting knob 13, thereby improving the efficiency of replacing the seat cushion body 17.

[0027] Working principle: When replacing the seat cushion body 17 using a stool that is easy to replace the seat cushion body 17, rotate the adjusting knob 13 according to the length of the seat cushion body 17. The adjusting knob 13 drives the threaded rod 4 to rotate, and the threaded rod 4 drives the threaded movable block 5 to move. The two groups of movable blocks 5 move to both sides of the threaded rod 4, so that the movable block 5 transmits the transmission rod 7 on the connecting piece 1 6. When the transmission rod 7 swings, it transmits the extension plate 9 on the connecting piece 2 8. The extension plate 9 slides out from the fixing frame 2 and pulls the pull rod 15. The pull rod 15 drives the limit rod 14 to retract and place the seat cushion body 17 on the rubber pad 16. Rotate the adjusting knob 13 in the opposite direction, and the extension plate 9 drives the support legs 19 to retract inward to fix both sides of the seat cushion body 17. Release the pull rod 15, and the limit rod 14 is reset by the rebound force of the spring 12 to fix the top surfaces on both sides of the seat cushion body 17, completing the replacement of the seat cushion body 17.

[0028] 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.
