A mounting tube 26 for the adjusting rod 32 to pass through is formed at the center of the connecting seat 2. The mounting tube 26 penetrates along its axial direction. A mounting hole 261 is formed, and a spiral protrusion 262 that cooperates with a spiral groove 321 is formed on the inner wall of the mounting hole 261, so that the abutment part 311 can be moved forward and backward for adjustment by rotating the abutment part 3, and the operation is very convenient and quick. An arc-shaped abutment surface a is formed on the front of the abutment part 311, and the arc-shaped abutment surface a is used to abut against the back of the user. The position of the adjustable arc-shaped abutment surface a can adapt to users of different body shapes. The annular guide cylinder 312 and the annular side plate 22 are mutually sleeved, so that the rotation of the abutment part 3 can be more stable, and the supporting strength of the abutment part 3 is better and will not shake.

[0023] An elastic buffer layer 33 is provided on the arc-shaped abutment surface a, and the elastic buffer layer 33 is snap-connected with the abutment portion 311.

[0024] The circular end plate 21 is formed with an elongated notch 24 extending from the rear to the support plate 231, and the elongated notch 24 forms an elongated hole 241 on the support plate 231 for the pivot shaft 133 to pass through, so that it is convenient for injection molding of the elongated hole 241 without the need to additionally process the elongated hole. Similarly, the circular end plate 21 is formed with an avoidance notch 25 extending from the rear to the support plate 231, and the avoidance notch 25 forms an avoidance opening 251 on the support plate 231 for avoiding the positioning portion 42, so that it is convenient for injection molding of the avoidance opening 251 without the need to additionally process the avoidance opening 251. The avoidance opening 251 can also limit the locking member 4 from being separated from the connecting seat 2.

[0025] The correction rod 1 includes a rod body and a connecting piece 13. The rod body includes a metal tube body 11 and a buffer sleeve 12 sleeved on the outside of the metal tube body 11. The buffer sleeve 12 is made of elastic materials such as foam. The connecting piece 13 includes a sleeve 131 and a connecting portion 132. The sleeve 131 and the connecting portion 132 are integrally injection molded. The sleeve 131 is fixedly sleeved on one end of the metal tube body 11. The other end of the metal tube body 11 is provided with a plug 14. The inner wall of the sleeve 131 is formed with a plurality of convex strips extending along its length direction and arranged circumferentially, which can increase The insertion strength between the sleeve 131 and the metal tube body 11 is increased, and the connecting part 132 is rotatably supported between the two support plates 231 through the pivot shaft 133, so that the correction rod 1 can be rotated between the unfolded state and the folded state. The four correction rods 1 in the unfolded state form a cross structure, and the four correction rods 1 in the folded state are close to each other. The locking piece 4 is arranged on the connecting seat 2 to limit the rotation of the correction rod 1 so that the correction rod 1 remains in the unfolded state, and the four correction rods 1 in the folded state are close to each other, which can reduce the storage space.

[0026] The four correction rods 1 in the unfolded state are in the same plane. This structure is more ergonomic and has a better correction effect. Of course, they can also be in different planes to achieve the effect of body correction.

[0027] Specifically, the pivot shaft 133 is a tube body with an axial notch, and the connecting portion 132 is formed with a through hole for the pivot shaft 133 to pass through. The pivot shaft 133 is inserted into the through hole and has an interference fit with the through hole, so that the two ends of the pivot shaft 133 protrude from both sides of the connecting portion 132 and extend into the elongated holes 241 of the two support plates 231, thereby realizing the rotational connection between the correction rod 1 and the adapter 23.

[0028] The correction rod 1 in the expanded state can abut against the front end face of the circular end plate 21 of the connecting seat 2. Specifically, the connecting seat 2 is formed with a rest groove 211 adapted to the connecting piece 13. The connecting piece 13 of the correction rod 1 in the expanded state abuts against the rest groove 211 to limit the correction rod 1 from swinging toward one side. The connecting part 132 is formed with a positioning notch 1321. The positioning notch 1321 and the rod body are located on both sides of the pivot shaft 133 and the positioning notch 1321 faces the front end face of the circular end plate 21 of the connecting seat 2.

[0029] The front section of the adjusting rod 32 of the abutting member 3 passes through the front end surface of the connecting seat 2, and the locking member 4 includes an operating tube 41 and four positioning parts 42. The operating tube 41 can be rotatably sleeved on the front section of the adjusting rod 32, and the four positioning parts 42 are circumferentially arranged on the outer peripheral surface of one end of the operating tube 41. The other end of the operating tube 41 is closed and formed with an operating part 43. The operating part 43 is a plate-shaped structure, which can facilitate the rotation operation of the operating tube 41, and can also form an anti-slip pattern 411 on the outer peripheral surface of the other end of the operating tube 41 to increase the friction force of rotating the operating tube 41. The locking member 4 can rotate between a first position and a second position. When the locking member 4 is in the first position, the positioning part 42 moves to between the front end surface of the circular end plate 21 and the positioning notch 1321 to limit the correction The straightening rod 1 rotates toward one side, and the circular end plate 21 can limit the correction rod 1 from rotating toward the other opposite side; when the locking piece 4 is in the second position, the positioning portion 42 moves to the avoidance opening 251, and the avoidance opening 251 simultaneously limits the locking piece 4 from being separated from the connecting seat 2, and the positioning portion 42 is formed with a limiting surface 421 inclined along its moving direction, and the limiting surface 421 can be rotated to be in close contact with the positioning notch 1321, and the inclined limiting surface 421 can make it easier for the positioning portion 42 to enter the positioning notch 1321 and make the limiting surface 421 in close contact with the positioning notch 1321, so that the correction rod 1 can be maintained in the expanded state without shaking. In addition to the above-mentioned structure, the locking piece 4 can also use a bolt as a locking piece, and the correction rod 1 can be locked in the expanded state by the bolt.

[0030] During assembly, the operating tube 41 of the locking member 4 is inserted into the front section of the adjusting rod 32, and at the same time, the four positioning parts 42 are installed from between the two supporting plates 231, and rotated at a certain angle to move the positioning parts 42 to the avoidance opening 251, and then the connecting part 132 of the connecting member 13 is rotatably connected to the two supporting plates 231 through the pivot shaft 133, so that the assembly of the locking member 4 and the correction rod 1 can be completed. In this way, one locking member 4 can simultaneously limit the four correction rods 1 to remain in the unfolded state or in the foldable state, thereby facilitating the switching of the body correction device between the unfolded state and the folded state.

[0031] When in use, the correction rod 1 is rotated to the unfolded state, and the four correction rods 1 form a cross-shaped structure, and then the locking piece 4 is rotated to make the positioning portion 42 fit tightly with the positioning notch 1321, thereby limiting the rotation of the correction rod 1; when it needs to be stored, the rotating locking piece 4 moves the positioning portion 42 to the avoidance opening 251, so that the positioning portion 42 is disengaged from the positioning notch 1321, and then the correction rod 1 can be rotated, so that the four correction rods 1 are rotated to a folded state close to each other.

[0032] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
