The metacarpophalangeal joint bridge 1 is a semi-circular arch structure with a hollow center, and a limiter 6 is located at its top. The finger root strap 2 is a symmetrical hollow structure with a circular opening at one end and a finger root buckle 3 at the other end. The finger root buckle 3 is hemispherical. The structure consists of a cylindrical upper and lower joint; the binding line 4 is a right-angled "S" shaped structure, connecting the two ends of the knuckle bridge 5; the knuckle bridge 5 is a double-arch bridge structure with a hollow center and a limiter 6 located at its top; the limiter 6 is a cylindrical tube structure; the glove connection hole 7 is a rectangular opening; the fingertip strap 8 is a symmetrical hollow structure with a rectangular opening at one end and a fingertip buckle 9 located at the other end; the fingertip buckle 9 is an upper and lower joint structure of a tiered platform and a cube; the fixator 10 is a rounded rectangular tube structure.

[0025] The metacarpophalangeal joint bridge 1 is a hollow semi-circular arch bridge structure with a radius of not less than 10mm and toothed edges at both ends. The limiter 6 is located on its top.

[0026] The finger root strap 2 is a symmetrical rounded rectangular plate-shaped hollow structure with serrated front and rear edges; the hollow part of the finger root strap 2 consists of two rectangular openings of different lengths arranged in a cross pattern, with the ratio of the two opening lengths being 5:3, the width being no less than 1mm, and the distance between the openings being greater than 1mm; one end of the finger root strap 2 is provided with several circular openings with a diameter of no less than 2mm, and the finger root buckle 3 is located at the other end of the finger root strap 2.

[0027] The finger root buckle 3 can be inserted into the circular opening of the finger root strap 2 by bending the finger root strap 2.

[0028] The binding line 4 is a right-angled "S" shaped structure with a width of not less than 1mm. Its two ends are connected to the front and rear ends of the knuckle bridge 5, respectively. The two binding lines 4 are symmetrically distributed on the left and right sides of the bottom of the knuckle bridge 5.

[0029] The knuckle bridge 5 is a hollow double-arch bridge structure with toothed edges at both ends, and the limiter 6 is located at its top.

[0030] The glove connection hole 7 consists of several rectangular openings with a length and width of not less than 4mm, distributed between the retainer 10 and the limiter 6 closest to the retainer 10. The glove connection hole 7 near the limiter 6 has beveled edges on both the front and back sides.

[0031] The fingertip strap 8 is a symmetrical rounded rectangular plate-shaped hollow structure with serrated front and rear edges; the hollow part of the fingertip strap 8 consists of two rectangular openings of different lengths arranged in a 5:3 ratio, with a width of not less than 1mm and a distance of more than 1mm between the openings; one end of the fingertip strap 8 has several rectangular openings with a length and width of not less than 2mm, and the fingertip buckle 9 is located at the other end of the fingertip strap 8; the length of the fingertip strap 8 is shorter than the length of the finger root strap 2.

[0032] The fingertip buckle 9 is a combination structure of a trapezoid and a cube. The top surface of the trapezoid is a square with a side length of less than 2mm, the bottom surface is a square with a side length of greater than 2.5mm, and the height is not less than 1mm. The length and width of the cube are both less than 2mm, and the height is greater than 1mm.

[0033] Specific implementation steps

[0034] During assembly, bend both ends of the finger root strap 2 downwards and connect the two ends of the finger root strap 2 together, and then fix it by inserting the finger root buckle 3 into the circular opening of the finger root strap; bend the finger tip strap 8 downwards at the position of the glove connection hole 7, and then bend the finger tip strap 8 upwards from the bottom, so that the two ends of the finger tip strap 8 are placed above the middle position between the knuckle bridge 5 and the foremost limiter 6, and fix it by inserting the finger tip buckle 9 into the rectangular opening of the finger tip strap.

[0035] In summary, this glove finger fixing device features a hollowed-out semi-circular arch bridge structure for the metacarpophalangeal joints and a hollowed-out double arch bridge structure for the finger joints, with toothed edges at both ends. This design prevents collisions with the metacarpophalangeal joints during use, ensuring comfort and reducing errors when collecting finger movement data. The symmetrical rounded rectangular plate-like hollowed-out finger root strap, with a circular opening at one end and a finger root buckle at the other end, provides elasticity and size adjustability, offering comfort and adaptability to different finger sizes. The finger root buckle allows for easy operation by bending the strap and inserting it through the circular opening, securing the finger root. Different buckles allow for size adjustment. The right-angled "S"-shaped binding thread, connected to both ends of the finger joint bridge and distributed on both sides, provides elasticity, increases overall structural strength, and achieves joint restraint.

[0036] Furthermore, this application utilizes rectangular openings for the glove connection holes, distributed between the retainer and the nearest limiter. The glove connection holes near the limiters are beveled on both sides, facilitating connection with the glove and ensuring easy assembly while preventing parts from detaching during donning and doffing. The fingertip straps feature symmetrical, rounded rectangular plate-like perforated structures with a rectangular opening at one end and a fingertip buckle at the other end, providing elasticity and size adjustability. This results in good comfort, adaptability to different finger sizes, and effective fixation. During use, the relative position of the fingers and the device does not easily change, hand movements are accurately captured, and tactile feedback is good. The design of the fingertip buckle, which combines the trapezoid and cube structures, prevents the fingertip strap from twisting and avoids finger slippage, resulting in good manipulation and control of objects. The design of the fingertip buckle, which allows the fingertip to be bent and inserted through the rectangular opening of the fingertip strap, can securely wrap around the fingertip, making operation convenient. Different fingertip buckles can be used to achieve size adjustment, thus effectively solving the problems and shortcomings of existing devices.
