Description

TECHNICAL FIELD The present disclosure belongs to the technical field of human posture correction appliances, and particularly relates to a height-adjustable back correction belt. BACKGROUND As an important product in the field of human posture correction appliances, back correction belts are widely used in daily office work, study, rehabilitation training, and other scenarios. The back correction belts mainly function to correct poor sitting and standing postures through applying external forces, which reduce spinal pressure, prevent and alleviate symptoms such as hunchback and scoliosis, and are of great significance for maintaining skeletal and muscular health. However, back correction belts in the prior art still have the following defects in practical application: 1. Back supports of back correction belts in the prior art are mostly of an integrated fixed-length design, and differences in heights and body shapes of different users are not fully considered. For example, Fixed-length supports cannot flexibly adapt to different users, because there exist significant differences in back lengths and spinal physiological curves between adults and adolescents, and between tall and petite individuals. For users with longer backs, supports are limited in coverage, and hardly effectively support key correction areas such as thoracic and lumbar vertebrae. For users with shorter backs, overlong supports easily lead to redundant restraints, compress body parts such as shoulder blades and waists, and cause soreness and discomfort, and even disuse due to poor wearing experience, thereby directly compromising the correction effect. 2. Although some back correction belts are provided with adjustment mechanisms as an attempt, most of them employ simple means of elastic band stretching or hook-and-loop fastener pasting for adjustments, which only achieves the adjustment of overall tightness, and has deficiencies of failure to precisely control height positioning of back supports, and easy displacement and loosening after the adjustment. Moreover, complicated adjustments and repeated disassembly and adjustment result in poor user convenience. 3. Support structures of back correction belts in the prior art mostly employ an integrated design of rigid materials, thereby resulting in lack of flexible adjustment space, easy localized pressure concentration for different back heights, and compression damage to the skin of shoulders and waists during long-term wearing. Additionally, poor compatibility between rigid support and dynamic human movement affects the flexibility of daily activities. Therefore, there is an urgent need for a back correction belt capable of flexibly adjusting a back support height to enhance adaptability and user experience. SUMMARY In order to overcome the above deficiencies in the prior art, the present disclosure provides a technical solution to solve the above problems. A height-adjustable back correction belt includes a waistband, where shoulder straps are disposed on two sides of an upper portion of the waistband, and a strap sleeve is mounted between the two shoulder straps in a penetrating manner; and a fixed portion is disposed in a middle of an upper portion of the waistband, a sliding portion is disposed on a rear side of the strap sleeve, the sliding portion is located above the fixed portion, a fixing member is disposed in the fixed portion, a sliding groove is formed in the sliding portion, the fixing member is installed in the sliding groove in a liftably and slidably fitted manner, and a limiting assembly is disposed between the fixing member and the sliding groove. Further, the waistband is made of a fabric with a hook-and-loop fastener loop patch, a back side of either of the shoulder straps is provided with a first hook-and-loop fastener hook patch, an end of a back side of the waistband is provided with a second hook-and-loop fastener hook patch, and both the first hook-and-loop fastener hook patch and the second hook-and-loop fastener hook patch are detachably fixed on the hook-and-loop fastener loop patch of the waistband. Further, a plurality of vertical support straps are arranged between the waistband and the fixed portion, and support strips are embedded in the vertical support straps. Optionally, the support strips are made of a metallic or non-metallic material, and the metallic material is any one of stainless steel, aluminum, and iron, and the non-metallic material is any one of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), fiberglass and ceramics. Further, a waist compression strap is disposed on the middle vertical support strap, back sides of both ends of the waist compression strap are provided with third hook-and-loop fastener hook patches, and the third hook-and-loop fastener hook patches are detachably fixed on the hook-and-loop fastener loop patch of the waistband. Further, the limiting assembly is fixedly installed at an upper end of the middle ve
