DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides an embodiment: a detachable traction frame, including a first shell 1 and a second shell 2, a first hinge rod 3 is hinged inside the first shell 1, a second hinge rod 4 is hinged inside the second shell 2, the second shell 2 is hingedly connected to the first hinge rod 3, a square sleeve 6 is sleeved on the second hinge rod 4, a connecting rod 10 is arranged on the second hinge rod 4, the connecting rod 10 is connected to a threaded rod 11 by a thread, and a support plate 12 is rotatably connected to the lower side of the threaded rod 11;

[0022] A folding mechanism, which is arranged on the second hinge rod 4 and is used to fold up the connecting rod 10;

[0023] An adjusting mechanism, which is disposed on the support plate 12 and is used to adjust the angle of the support plate 12;

[0024] Furthermore, a fixed block 5 is fixedly connected to the first hinged rod 3, a limiting block 7 is fixedly connected to the square sleeve 6, and a limiting groove 8 adapted to the limiting block 7 is provided on the fixed block 5. The structure can connect the fixed block 5 and the square sleeve 6 by inserting the limiting block 7 into the limiting groove 8. The square sleeve 6 shields the connection between the first hinged rod 3 and the second hinged rod 4 so that the first hinged rod 3 and the second hinged rod 4 remain in a horizontal state.

[0025] Furthermore, the folding mechanism includes a second hinged rod 4, which is provided with a fixing groove 9, and a connecting rod 10 is rotatably connected inside the fixing groove 9. The thickness of the connecting rod 10 is smaller than the opening diameter of the fixing groove 9. This structure can cover the opening of the fixing groove 9 after the fixing block 5 and the square sleeve 6 are disconnected, thereby preventing the connecting rod 10 from rotating out and affecting the overall folding.

[0026] Furthermore, a cushion 13 is provided on the support plate 12, and the size of the cushion 13 is consistent with the size of the support plate 12. This structure can prevent the side of the support plate 12 from scratching the user's skin.

[0027] Furthermore, the adjustment mechanism includes a threaded rod 11, a rotating shaft 14 is arranged between the threaded rod 11 and the support plate 12, a slot 15 is opened on the rotating shaft 14, a clamping block 16 is fixedly connected to the upper side of the support plate 12, and the clamping block 16 is engaged in the slot 15. This structure allows the support plate 12 to be maintained after being rotated to a certain angle.

[0028] Furthermore, an iron sheet 17 is fixedly connected to the left side of the second shell 2, and a magnet 18 is fixedly connected to the rear side of the threaded rod 11. This structure can fix the support plate 12 to the left side of the second shell 2 by magnetic attraction.

[0029] Working principle: When in use, the first shell 1 and the second shell 2 are pulled apart to the left and right, so that the first hinge rod 3 and the second hinge rod 4 are unfolded upward in a horizontal state, and the square sleeve 6 is pushed to insert the limit block 7 into the limit groove 8, so that the first hinge rod 3 and the second hinge rod 4 can be fixed to keep them in a horizontal state and will not rotate. When the square sleeve 6 is pushed, the connecting rod 10 that is rotatably connected inside the fixing groove 9 without covering it can fall naturally. At this time, the magnetic support plate 12 on the left side of the second shell 2 can be removed, and the threaded rod 11 can be aligned with the lower side of the connecting rod 10 to screw the threaded rod 11 into the connecting rod 10 through the thread action. The connecting rod 10 can be connected to the support plate 12. After the user puts his legs on the support plate 12, he can push the support plate 12 left and right, so that the block 16 fixedly connected to the support plate 12 is squeezed, deformed and displaced in the slot 15. The block 16 can be deformed by elastic force and stuck in the slot 15 at different positions, so that the support plate 12 can be rotated to the left and rear at a certain angle and maintained continuously. After the angle is adjusted, it can meet the different traction angle requirements of the user. When not in use, the support plate 12 can be directly magnetically attracted to the left side of the second shell 2 through the iron sheet 17 and the magnet 18 to prevent the support plate 12 from being lost. The above is the entire working principle of the utility model.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
