One side of each of the two mating rods 11 extends through the mating groove 6 to the outside of the support plate 1. The opposite sides of each of the two mating rods 11 are provided with toothed grooves 12, and there are multiple toothed grooves 12. The inner cavity of each toothed groove 12 is connected to six teeth 13. A U-shaped plate 14 is fixedly connected to the rear side of the support plate 1, and the front side of the U-shaped plate 14 is fixedly connected to the teeth 13. Control rods 15 are fixedly connected to the left and right sides of the rear side of the support plate 1, and the front side of the control rods 15 extends through the U-shaped plate 14 and connects to the support plate 1. Plate 1 is fixedly connected. The inner cavity of U-shaped plate 14 is provided with a fixing structure 16. The fixing structure 16 includes a movable groove 101, which is opened in the inner cavity of U-shaped plate 14. Movable blocks 102 are fixedly connected to the left and right sides of the inner cavity of the movable groove 101.

The opposite side of the two control rods 15 is provided with a function to cooperate with the locking rods 103. The slot 105 has a locking rod 103 that passes through the movable slot 101 and extends into the inner cavity of the slot 105 on the side near the slot 105. The movable slot 101 has a movable hole 106 on the rear side. Pulling members 107 are movably connected to the left and right sides of the inner cavity of the movable hole 106.

An L-shaped rod 18 is inserted into the inner cavity of the insertion slot 17. The bottom of the L-shaped rod 18 is fixedly connected to the pulling member 107.

[0026] Specifically, by setting up the extrusion assembly 7, the mating rod 11, the toothed groove 12, the tooth 13, the U-shaped plate 14, the control rod 15, the fixing structure 16, the insertion slot 17, and the L-shaped rod 18, the rotation of the stabilizing rod 71 drives the rotating plate 72 to rotate, and the rotation of the rotating plate 72 drives the extrusion rod 74 to rotate. At this time, the lying plate 3 can be rotated. The tooth 13 is inserted into the toothed groove 12 at different positions, which can fix the position of the mating rod 11 of the rotating plate 72. The U-shaped plate 14 can easily drive the tooth 13 to move. The control rod 15 can easily drive the U-shaped plate 14 to move. The locking rod 103 is inserted into the locking slot 105, which can fix the position of the U-shaped plate 14. The pulling member 107 drives the L-shaped rod 18 to be inserted into the insertion slot 17, which can then position the head plate 9, thus facilitating the folding of the training device.

[0027] Furthermore, when assisting different individuals in thyroid posture training, pulling the two pullers 107 causes the movable block 102 to compress the first spring 104 within the movable groove 101. The movement of the movable block 102 causes the locking rod 103 to disengage from the locking groove 105. Subsequently, pulling the pullers 107 causes the U-shaped plate 14 to move. The movement of the U-shaped plate 14 causes the teeth 13 to disengage from the tooth groove 12. Then, rotating the mating rod 11 causes the stabilizing rod 71 to rotate. The rotation of the stabilizing rod 71 causes the rotating plate 72 to rotate. The rotation of the rotating plate 72 causes the squeezing rod 104 to disengage from the groove 104. The pressure rod 74 presses the inner wall in the extrusion groove 73, which drives the rotating rod 4 on the lying plate 3 to rotate. When the lying plate 3 rotates to the appropriate position, it pushes the U-shaped plate 14 to drive the teeth 13 to insert into the tooth groove 12. The teeth 13 can position the stabilizing rod 71, the mating rod 11, the extrusion rod 74 and the lying plate 3. Then, the pulling member 107 is released, and the first spring 104 will undergo elastic deformation, which drives the locking rod 103 on the movable block 102 to insert into the locking groove 105. At this time, the position of the U-shaped plate 14 can be fixed.

[0028] Example 3 The third embodiment of this utility model provides an adjustable thyroid posture training device. Positioning rods 19 are fixedly connected to opposite sides of the connecting plate 8. The right side of the positioning rods 19 penetrates the connecting plate 8 and extends to the outside of the connecting plate 8. Multiple docking grooves 20 are formed on the surface of the positioning rods 19. The positioning assembly 10 includes a movable groove 161, which is formed in the inner cavity of the head plate 9. A movable shell 162 is movably connected to the inner cavity of the movable groove 161. A movable plate 163 is movably connected to the inner cavity of the movable shell 162. The front side of the movable plate 163 is fixedly connected to... A docking plate 164 is provided to cooperate with the docking groove 20. The front side of the docking plate 164 passes through the moving groove 161 and extends into the inner cavity of the docking groove 20. The top and bottom of the moving shell 162 are provided with oblique holes 165. The inner cavity of the oblique hole 165 is movably connected to a pressing block 166. The side of the pressing block 166 near the moving plate 163 is fixedly connected to the moving plate 163. A pull rod 167 is fixedly connected to the left side of the moving shell 162. The front and rear sides of the surface of the pull rod 167 are fitted with second springs 168. The left side of the pull rod 167 passes through the moving groove 161 and extends to the outside of the head plate 9.

[0029] Specifically, by setting a positioning rod 19, a docking groove 20, and a positioning component 10, the rotation of the positioning rod 19 can control the rotation position of the head plate 9. The docking plate 164 can be inserted into the docking groove 20 at different positions to fix the head plate 9 at different positions. The pressure of the second spring 168 on the moving shell 162 can then position the moving shell 162 and the moving plate 163. The cooperation of the oblique hole 165 and the pressing block 166 can easily drive the moving plate 163 to move.

[0030] Furthermore, when the head plate 9 needs to be adjusted, pulling the lever 167 moves the movable shell 162 to compress the second spring 168. When the movable shell 162 moves, the oblique hole 165 compresses the compression block 166, which moves the compression block 166. The movement of the compression block 166 moves the movable plate 163, which in turn moves the docking plate 164 out of the docking groove 20. Then, the head plate 9 rotates around the positioning rod 19. After releasing the lever 167, the second spring 168 undergoes elastic deformation, causing the movable shell 162 to return to its original position. At this time, the movable shell 162 can move the movable plate 163 through the oblique hole 165. The movement of the movable plate 163 will cause the docking plate 164 to be inserted into the docking groove 20, thus fixing the position of the head plate 9.

[0031] Working principle: When assisting different individuals in thyroid posture training, pulling the two pullers 107 causes the movable block 102 to compress the first spring 104 within the movable groove 101. The movement of the movable block 102 causes the locking rod 103 to disengage from the locking groove 105. Subsequently, pulling the pullers 107 causes the U-shaped plate 14 to move. The movement of the U-shaped plate 14 causes the teeth 13 to disengage from the tooth groove 12. Then, rotating the mating rod 11 causes the stabilizing rod 71 to rotate. The rotation of the stabilizing rod 71 causes the rotating plate 72 to rotate. The rotation of the rotating plate 72 causes the compression rod to rotate. 74. The inner wall is squeezed in the extrusion groove 73, which will drive the rotating rod 4 on the lying plate 3 to rotate. When the lying plate 3 rotates to the appropriate position, the U-shaped plate 14 is pushed to drive the tooth 13 to insert into the tooth groove 12. The tooth 13 can position the stabilizing rod 71, the cooperating rod 11, the extrusion rod 74 and the lying plate 3. Then the pulling member 107 is released, and the first spring 104 will undergo elastic deformation to drive the locking rod 103 on the movable block 102 to insert into the locking groove 105. At this time, the position of the U-shaped plate 14 can be fixed. When the head plate 9 needs to be adjusted, pull the lever 167 to move the movable shell 162 and compress the second spring 168. When the movable shell 162 moves, the oblique hole 165 will compress the compression block 166 and move it. The movement of the compression block 166 will drive the movable plate 163 to move. The movement of the movable plate 163 will drive the docking plate 164 to disengage from the docking groove 20. Then, rotate the head plate 9 around the positioning rod 19. Then release the lever 167. The second spring 168 will undergo elastic deformation and drive the movable shell 162 back to its original position. At this time, the movable shell 162 can drive the movable plate 163 to move through the oblique hole 165. The movement of the movable plate 163 will drive the docking plate 164 to be inserted into the docking groove 20. At this time, the position of the head plate 9 can be fixed.

[0032] In summary, the adjustment effect is achieved through the cooperation of the extrusion assembly 7, connecting plate 8, head plate 9, positioning assembly 10, stabilizing rod 71, rotating plate 72, extrusion groove 73, extrusion rod 74 and fixing structure 16.
