A locking plate 4 is rotatably mounted on the buckle 3, a support block 5 is slidably mounted on the support rod 2, a sliding sleeve 6 is fixedly mounted on the bottom of the support block 5, the sliding sleeve 6 is slidably mounted on the support rod 2, a bolt 7 is installed on the internal thread of the sliding sleeve 6, an adjustment groove 8 is opened on the support rod 2, a locking strip 9 is slidably mounted inside the support block 5, a connecting block 10 is fixedly mounted on one end of the locking strip 9, a fixing sleeve 11 is sleeved on the connecting block 10, a fixing mechanism 12 is provided on one side of the base 1, a four-corner frame 13 is fixedly mounted on the bottom of the base 1, a self-locking universal wheel 14 is installed on the bottom of the four-corner frame 13, a pull handle 15 is fixedly mounted on the top of the support rod 2, a backrest 16 is fixedly mounted on the fixing sleeve 11, an adjustment rod 17 is fixedly mounted on the buckle 3, a seat cushion 18 is provided at the bottom of the backrest 16, a rod sleeve 19 is fixedly mounted at the bottom of the seat cushion 18, the adjustment rod 17 is slidably mounted inside the rod sleeve 19, and a screw 20 is installed on the internal thread of the adjustment rod 17 and the rod sleeve 19.

[0023] First, pull the backrest 16 to adjust the distance between the backrest 16 and the child's back. Then, pull the sliding sleeve 6, which moves the support block 5. The movement of the support block 5 moves the locking strip 9, which in turn moves the connecting block 10. The movement of the connecting block 10 moves the fixing sleeve 11, which in turn moves the backrest 16. Next, rotate the bolt 7 to insert it into the adjustment slot 8. This allows you to adjust the height of the backrest 16 to suit different children. Finally, rotate the screw 20. When the screw 20 moves out of the adjustment rod 17, pull the seat cushion 18 to adjust its forward and backward position. Position the seat cushion 18 by turning the screw 20 into the adjusting rod 17. Pull the latch 4 to adjust the height of the buckle 3, thereby adjusting the height of the seat cushion 18. The fixing mechanism 12 can fix the children's study chair to the ground, preventing the chair from moving due to being touched during study, which could distract the child and cause safety hazards. The self-locking casters 14 can easily move the children's study chair. After moving it, the self-locking components on them can be used to fix its position. The handle 15 can easily pull the children's study chair.

[0024] In this embodiment of the utility model, specifically, the fixing mechanism 12 includes a mounting plate 121 fixedly installed at the bottom of the four-corner frame 13, a mounting strip 122 fixedly installed on the mounting plate 121, a mounting box 123 fixedly installed at the other end of the mounting strip 122, a spring 124 fixedly installed inside the mounting box 123, a moving block 125 fixedly installed at the other end of the spring 124, the moving block 125 slidably installed inside the mounting box 123, a moving rod 126 fixedly installed inside the moving block 125, the moving rod 126 slidably installed inside the mounting box 123, a fixing strip 127 fixedly installed at the bottom of the moving rod 126, and a foot pedal 128 fixedly installed at the top of the moving block 125.

[0025] To secure the child's study chair, the child sits on the seat cushion 18 with both feet on the foot pedal 128. The foot pedal 128 moves the moving block 125, which in turn moves the moving rod 126, which in turn moves the fixing strip 127. When the fixing strip 127 moves to the ground, it increases the friction with the ground, thus securing the child's study chair and preventing it from moving due to being touched while studying, which could distract the child and create safety hazards. When the child lifts their feet, the moving block 125 returns to its original position due to the spring 124, which in turn moves the fixing strip 127 off the ground.

[0026] Working principle: In use, first pull the backrest 16 to adjust the distance between the backrest 16 and the child's back. Pull the sliding sleeve 6, which moves the support block 5. The movement of the support block 5 moves the locking strip 9, which moves the connecting block 10. The movement of the connecting block 10 moves the fixing sleeve 11, which moves the backrest 16. Then, turn the bolt 7 to insert it into the adjustment slot 8. This allows you to adjust the height of the backrest 16 to suit different children. The child sits on the seat cushion 18 with both feet on the foot pedal 12. 8. When the foot pedal 128 moves the moving block 125, the moving block 125 moves the moving rod 126, and the moving rod 126 moves the fixing strip 127. When the fixing strip 127 moves to the ground, the friction with the ground is increased, thus fixing the child's study chair and preventing it from moving when touched during study, which could distract the child and cause safety hazards. When the feet are lifted, due to the spring 124, the moving block 125 returns to its original position, which in turn moves the fixing strip 127 off the ground.
