[0028] The following is a detailed explanation of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0029] Reference Figures 1 to 8 A lever-type hallux valgus corrector comprises a metatarsal support 4, a thumb support 2, a base 1 and a knob 3. The base 1 is arranged between the metatarsal support 4 and the thumb support 2. One end of the base 1 is vertically rotatably connected to the metatarsal support 4, and the other end of the base 1 is horizontally rotatably connected to the thumb support 2. The pressing end of the thumb support 2 is bent, and the knob 3 is covered on the pressing end of the thumb support 2. The knob 3 is movably rotatably connected to the base 1 and presses the pressing end of the thumb support 2.

[0030] Reference Figure 1 , Figure 4 and Figure 5 , the left end of the metatarsal support 4 is in the shape of a long blade, the right end of the metatarsal support 4 is circular, and the left end of the metatarsal support 4 is successively provided with a heel fixing platform 41 and two pairs of sole fixing holes 42 from left to right. The heel fixing platform 41 is vertically arranged and is in a U shape. A heel fixing band 71 is connected to the heel fixing platform 41. The two pairs of sole fixing holes 42 are arranged at intervals in a row. A sole fixing band 7 is connected between the two pairs of sole fixing holes 42. Specifically, the two ends of the sole fixing band 7 respectively pass through the same pair of sole fixing holes 42, so that the whole sole fixing band 7 is in a circular shape during use for tying around the sole. One end of the heel fixing band 71 bypasses the heel fixing platform 41, and the other end of the heel fixing band 71 is pasted on the outer side of the sole fixing band 7, so that the whole heel fixing band 71 is in a U shape for surrounding the heel. The heel fixing band 71 and the sole fixing band 7 can jointly tie the heel to prevent the metatarsal support 4 from sliding forward. On the side of the right end of the metatarsal support 4 away from the base 1, there is a groove 43, and a fixing piece 121 is received in the groove 43. The thickness of the fixing piece 121 is less than the depth of the groove 43. An inner pad 6 is superposed on the side of the metatarsal support 4 away from the knob 3. The inner pad 6 is relatively soft, which can prevent the corrector from chafing the human skin and make the human body feel more comfortable.

[0031] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 , on the base 1, a T-shaped groove and a nut 14 are successively arranged at intervals from left to right. A T-shaped pin 12 is installed in the T-shaped groove. The pin 12 successively passes through the base 1 and the metatarsal support 4 and extends into the groove 43. The base 1 is vertically rotatably connected to the metatarsal support 4 through the pin 12. The fixing piece 121 is sleeved on the end (i.e., the lower end) of the pin 12. The metatarsal support 4 is located between the base 1 and the fixing piece 121. The pin 12 and the fixing piece 121 are combined to form a "work" shape, which can connect the metatarsal support 4 and the base 1, so that when people walk, the rotating part of the metatarsophalangeal joint and the metatarsal support 4 match and adapt to each other. The nut 14 is an annular metal part and passes through the base 1. In order to increase the strength between the nut 14 and the base 1, in the present utility model, the nut 14 and the base 1 are integrally formed by injection molding (i.e., insert molding, insertmolding). On the side of the base 1 close to the metatarsal support 4, there is an installation hole 131. On the inner side wall of the base 1, there is a side groove 13. The side groove 13 communicates with the installation hole 131 and is located on the side of the installation hole 131. On the outer wall of the base 1 close to the metatarsal support 4, there is a mark 11. The position of the mark 11 corresponds to the position of the side groove 13. At one end of the base 1 close to the thumb support 2, there is a rotating shaft 15.

[0032] Referring to Figures 2 to 6 A U-shaped clamping member 5 is installed in the mounting hole 131 of the base 1, and an L-shaped clamping arm 51 is provided on the inner wall of the clamping member 5. The end of the clamping arm 51 passes through the side groove 13 of the base 1 and extends into the base 1 to form a clamping position 511, so that the clamping position 511 is elastically protruded on the inner wall of the base 1, and the position of the clamping position 511 also corresponds to the position of the mark 11.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The thumb support 2 is Z-shaped as a whole, the left end of the thumb support 2 is bent to form a pressing end, the right end of the thumb support 2 is an adjustment end, the base 1 is horizontally rotatably connected to the thumb support 2 through a rotating shaft 15, a clearance hole 21 is provided at the pressing end of the thumb support 2, and two thumb fixing holes 22 for connecting the thumb fixing belt 72 are provided at intervals at the right end of the thumb support 2. The two ends of the thumb fixing belt 72 pass through the two thumb fixing holes 22 respectively, so that the thumb fixing belt 72 is ring-shaped, which is convenient for tying on the thumb, and the rotating shaft 15 is located between the clearance hole 21 and the two thumb fixing holes 22.

[0034] Reference Figure 2 , Figure 5 and Figure 8 The knob 3 is circular, and a stud 33 is vertically fixed on the knob 3. In the utility model, in order to increase the strength between the stud 33 and the knob 3, the stud 33 and the knob 3 are formed by injection molding (i.e., insert molding). The stud 33 passes through the clearance hole 21 on the thumb support 2 and is threadedly connected with the nut 14. A circle of scales 31 is provided along the edge of the outer end surface of the knob 3. A plurality of clip strips 32 are arranged on the outer wall of the knob 3 at intervals, and a slot 321 is formed between two adjacent clip strips 32. The plurality of slots 321 are arranged at intervals around the outer wall of the knob 3 in a circle. The clip position 511 can cooperate with any slot 321 to prevent the knob 3 from rotating by itself without adjustment, thereby preventing misoperation. At the same time, the clip position 511 can also generate a sound during the switching of the slot 321 to remind the user that the knob 3 is in a rotating state.

[0035] Reference Figures 1 to 8 The working principle of the lever-type hallux valgus corrector of the utility model is:

[0036] First, place the entire corrector on the side of the foot; then hold the thumb fixing belt 72 and wrap it around the thumb, and tie the thumb support 2 to the thumb; then wrap the sole fixing belt 7 around the sole of the foot, tie the metatarsal support 4 to the side of the metatarsal, and finally wrap the heel fixing belt 71 around the heel and stick it to the sole fixing belt 7. At this time, the entire corrector is tied to the foot that needs to correct the thumb;

[0037] The user manually rotates the knob 3 to a certain angle. Since the stud 33 on the knob 3 is threadedly matched with the nut 14 on the base 1, the knob 3 gradually approaches the base 1 during the rotation process, thereby pressing the pressing end of the thumb support 2. Based on the principle of leverage, the right end of the thumb support 2 will tilt outward, pulling the thumb outward, thereby controlling the eversion of the bound thumb and achieving the purpose of correction.

[0038] When the thumb is turned outward at an excessively large angle, the user can further reverse the knob 3 to move the knob 3 away from the base 1, thereby reducing the pressing force applied by the knob 3 to the pressing end of the thumb support 2. At this time, the thumb support 2 can be rotated in the opposite direction to further reduce the thumb turnout angle, so as to adjust the thumb turnout angle to a suitable angle.

[0039] When the user walks normally, the heel of the foot will be lifted diagonally upward. At this time, the metatarsal support 4 will adaptively rotate around the pin 12 on the base 1 as the heel of the human body is lifted, so that the corrector can adapt to the movement of the human foot, making it convenient for the user to walk normally while using the corrector without affecting the user's normal life.

[0040] The lever-type hallux valgus corrector of the utility model forms a lever structure by horizontally rotating the connected thumb support member 2 on the base 1. The pressing end of the thumb support member 2 can be pressed by directly rotating the knob 3, and then the horizontal rotation angle of the thumb support member 2 can be controlled labor-savingly by utilizing the lever principle, so as to achieve the purpose of quickly adjusting the angle of the hallux valgus. The entire corrector is not only easy to operate, but also labor-saving in angle adjustment, and is convenient for users to use.

[0041] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
