Locking slots 14 are installed on both sides of the plastic spine traction sleeve 7. A limiting support frame 18 is provided on one side of the back-fitting arc frame 9. Symmetrical elastic axle pins 39 are installed on both sides of the limiting support frame 18. The symmetrical elastic axle pins 39 are used to be symmetrically inserted in the locking slots 14. Side brackets 22 are also provided on both sides of the installation base frame 1. A leg support frame 23 is installed at the lower end of the side bracket 22. A first leg side frame 25 is provided on one side of the leg support frame 23, and a second leg side frame 26 is provided on one side of the first leg side frame 25. Fitting inner grooves 29 are provided at both ends of the first leg side frame 25, and positioning protrusions 31 are provided at both ends of the second leg side frame 26. The positioning protrusions 31 are used to be inserted into the interior of the positioning slot 30.

[0030] The outer side of the plastic spine traction sleeve 7 is arranged with a back fitting arc frame 9. When worn, the plastic spine traction sleeve 7 equipped with the back fitting arc frame 9 is fitted to the back of the user, and the protruding position of the curve of the plastic spine traction sleeve 7 is fitted to the waist of the user through the outer surface of the back fitting arc frame 9, and the mounting base frame 1 is determined according to the mounting position of the plastic spine traction sleeve 7. The height of the fixed position of the mounting base frame 1 is determined, and the first leg side frame 25 is fitted to the outer side of the user's leg, and the second leg side frame 26 is correspondingly clamped on one side of the first leg side frame 25 through the cooperation of the positioning protrusion 31 and the fitting inner groove 29, so as to achieve a connection effect on the user's legs and provide a secure connection for the user. The base frame 1 is installed to play a supporting role, and then one end of the locking tongue 4 is embedded in the fixed inner groove 5. By positioning the gap of the side groove 6 itself, it can be ensured that one end of the locking tongue 4 is completely embedded in the fixed inner groove 5 to form a locked state. When in use, when the user needs to bend down, through the material properties of the plastic spine traction sleeve 7, the whole can provide a large degree of bending during use. When bending, the elastic effect of the traction support steel belt 15 can be used to shape, support and rebound the plastic spine traction sleeve 7, providing the user with waist resetting, rebound and support effects, greatly reducing the support pressure on the waist, and avoiding the user from standing for a long time and causing lumbar strain.

[0031] Example 2

[0032] It is necessary to provide a support flipping support effect for the mounting base 1, increase the degree of fit between the user's waist and back and the arc frame 9, and improve the support effect on the user's waist. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 A pressure box 24 is provided on the outside of the leg support frame 23, a support shaft ring 32 is provided at the lower end of the side bracket 22, a tensile steel bar 40 is installed on the outside of the support shaft ring 32, a support bottom ring 33 is installed inside the pressure box 24, a support upper ring 34 is installed above the support bottom ring 33, the support upper ring 34 is connected to the support bottom ring 33 by a contraction spring 35, and one end of the tensile steel bar 40 is connected to the upper end of the support upper ring 34.

[0033] The clamping force of the contraction spring 35 provides a tightening effect on the support upper ring 34, pulling the support upper ring 34 downward, thereby driving the downward force of the tensile steel bar 40. Through the connection effect between one end of the tensile steel bar 40 and the outer side of the support shaft ring 32, the downward force of the tensile steel bar 40 is converted into the rotational force of the support shaft ring 32. Figure 4As shown, the support shaft ring 32 rotates clockwise, and one end of the support shaft ring 32 is an integral structure with the lower end of the side bracket 22. When the support shaft ring 32 rotates clockwise, it can drive the mounting base 1 to flip as a whole. When the mounting base 1 flips, the force is transmitted to the plastic spine traction sleeve 7, and the bending function of the lower end of the plastic spine traction sleeve 7 is realized through the movable groove 13. When in use, the flipping force of the mounting base 1 is transmitted to the bending area of ​​the lower end of the plastic spine traction sleeve 7, and the user's waist in the bending area can be lifted up, thereby achieving a supporting effect on the user's waist position and further alleviating the load on the user's waist.

[0034] Example 3

[0035] The extension degree of the contraction spring 35 lacks an adjustment structure and is difficult to adapt to various situations. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-6 A support screw 36 is installed at the bottom of the pressure box body 24, and the support screw 36 is used to be threadedly engaged with the support bottom ring 33.

[0036] Through the threaded engagement connection between the support screw 36 and the support bottom ring 33, when the support screw 36 is rotated, the support bottom ring 33 can be driven to descend, and the distance between the support upper ring 34 and the support bottom ring 33 can be increased, and the support distance of the contraction spring 35 can be extended, thereby increasing the tension of the contraction spring 35, and vice versa. A hexagonal pin is provided at the lower end of the support screw 36, and the tightness of the contraction spring 35 can be adjusted by rotating the support screw 36, so that the device can adjust the tightness between the mounting base 1 and the plastic spine traction sleeve 7 according to the user's usage.

[0037] Example 4

[0038] The lower end of the plastic spine traction sleeve 7 fits the waist of the user, and the fitting part needs a higher degree of bending to adapt to the user's activities. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 A movable notch 13 is provided on the outer side of the plastic spine traction sleeve 7 .

[0039] The slot structure of the plastic spine traction sleeve 7 enables the plastic spine traction sleeve 7 to have a higher curvature when bent, thereby ensuring that the flexibility of the plastic spine traction sleeve 7 is improved when the user bends the waist, thereby increasing the range of activities supported by the device.

[0040] Example 5

[0041] The back fitting arc frame 9 is in direct contact with the user's back, which may increase the user's discomfort if used for a long time. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6A bonding surface layer 19 is installed on the outer side of the back bonding arc frame 9.

[0042] The material of the fitting surface layer 19 is a flexible rubber material. This material effect can ensure that the fitting surface layer 19 fits the back of the user while improving the user's comfort and increasing the convenience of using the device, thereby increasing the comfort of the device.

[0043] Example 6

[0044] The interior of the bonding surface layer 19 lacks a supporting structure, which will affect its comfort when used for a long time. This embodiment is an improvement made on the basis of embodiment 5. For details, please refer to Figure 1-6 A folding edge cover 38 is provided on the outside of the fitting surface layer 19 , and a supporting spring 21 is installed inside the fitting surface layer 19 .

[0045] The supporting spring 21 provides support to the fitting surface layer 19. At the same time, the elastic effect of the supporting spring 21 allows the fitting surface layer 19 to elastically support the fitting surface layer 19 when it fits against the user's back, thereby alleviating the supporting pressure of the fitting surface layer 19 and increasing the service life of the fitting surface layer 19.

[0046] Example 7

[0047] The user's back skin is in contact with the contact surface layer 19 for a long time, which may affect the comfort. This embodiment is an improvement made on the basis of embodiment 6. For details, please refer to Figure 1-6 A fitting support net 37 is provided inside the fitting surface layer 19, and a ventilation inner hole 20 is provided inside the back fitting arc frame 9.

[0048] Through the structural characteristics of the fitting support net 37 and the ventilation inner hole 20 and the cooperation between the two, after fitting with the user's back, a ventilation and heat dissipation effect is provided, thereby preventing the fitting surface layer 19 from fitting with the user's back for a long time and causing discomfort to the user's back skin.

[0049] Example 8

[0050] The connection method between the second leg side frame 26 and the first leg side frame 25 is not stable enough, which may easily cause the first leg side frame 25 to separate from the second leg side frame 26. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 Both ends of the second leg side frame 26 are provided with fitting outer grooves 28 , and both ends of the first leg side frame 25 are also provided with positioning notches 30 , and the positioning protrusions 31 are used to be stuck inside the positioning notches 30 .

[0051] When the first leg side frame 25 is connected to the second leg side frame 26, the two ends of the second leg side frame 26 are first retracted inward, and then the two ends of the second leg side frame 26 are respectively clamped in the fitting inner grooves 29 at the two ends of the first leg side frame 25, and at the same time, the positioning protrusion 31 is clamped in the positioning notch 30 to form a fixed connection state, thereby improving the degree of fixation between the two.

[0052] Example 9

[0053] The second leg side frame 26 lacks an outward elastic effect, and it is difficult to ensure that the two ends of the second leg side frame 26 are stable when connected to the first leg side frame 25. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 A bending bracket 27 is provided inside the second leg side frame 26 .

[0054] The bending bracket 27 is made of elastic plastic material, which provides a connection support function for the second leg side frame 26, and at the same time increases the bending toughness of the second leg side frame 26, ensuring that the second leg side frame 26 provides a higher outward elastic force when connected to the first leg side frame 25, ensuring that the positioning protrusion 31 is embedded in the interior of the positioning groove 30, thereby providing convenient installation and support effect for the device.

[0055] Example 10

[0056] The back fitting arc frame 9 located at the user's waist position requires a large thrust to lift the user's waist position. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-6 , support through holes 11 are provided on both sides of one back-fitting arc frame 9 , and the support through holes 11 are used to support and fix the shoulder strap 10 .

[0057] When the device is worn, the fixing strap 10 can be cross-connected to the user's chest, and one end of the fixing strap 10 can be passed through the inside of the supporting through hole 11 and then connected to the fixing seat 12. During use, the fixing strap 10 passes through the inside of the supporting through hole 11 to support one of the back-fitting arc frames 9, so that the back-fitting arc frame 9 can support the user's waist while realizing the connection between the device and the user.
