[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Embodiment 1

[0036] Refer to the attached drawings of the specification, such as Figure 1-Figure 4 As shown, a wrist guard for tenosynovitis includes a main support 1, an extension support 2, a wrist strap 3 and a thumb strap 4. The inner side of the main support 1 is open, and a plurality of hollow grooves 14 are arranged on the outer side. Part of the main support 1 is arranged in an arc shape, and when the wrist is put into the wrist guard, the main support 1 fits the wrist. The extension support 2 is integrally connected to the main support 1, one side of the extension support 2 is open, and the other side is hollowed out. Part of the extension support 2 is arranged in an arc shape, and when the thumb is put into the wrist guard, the extension support 2 fits the thumb. The wrist strap 3 is located on one side of the opening of the main support, and its two ends are fixedly connected to the two sides of the main support 1 respectively; the thumb strap 4 is located on one side of the opening of the extension support 2, and its two ends are fixedly connected to the two sides of the extension support 2 respectively. The material of the main support 1 and the extension support 2 can be selected from PC plastic or ABS plastic.

[0037] By hollowing out the main support 1 and the extension support 2, the contact and friction of the tenosynovitis wrist guard on the human hand joints can be reduced during wearing, thereby improving the comfort of wearing the tenosynovitis wrist guard; at the same time, the hollowing out of the main support 1 and the extension support 2 can also reduce the overall weight of the tenosynovitis wrist guard.

[0038] like Figure 1-Figure 4 As shown, when the wrist strap 3 and the thumb strap 4 are installed, Velcro can be provided at the ends of the wrist strap 3 and the thumb strap 4. A wire hole 5 is provided on one side of the main bracket 1 and the extension bracket 2; one end of the wrist strap 3 and the thumb strap 4 passes through and wraps around the wire hole 5, and then is fixed by the Velcro at the end thereof; the other end of the wrist strap 3 and the thumb strap 4 passes through the hollow part and is directly wrapped around the main bracket 1 and the extension bracket 2. The material of the wrist strap 3 and the thumb strap 4 can be selected from elastic honeycomb fabric or breathable mesh.

[0039] In order to enhance the fixation between the main support 1 and the wrist, the number of wrist straps 3 can be multiple. Figure 1As shown, when there are two or more wrist straps 3, the number of the wire holes 5 located on the same side of the main bracket 1 is multiple, and corresponds to the number of wrist straps 3. When the multiple wrist straps 3 are fixed, a gap is left between two adjacent wrist straps 3, and the position of the hand joint corresponds to the gap between the two wrist straps 3, so as to prevent the wrist straps 3 from affecting the joint movement of the human hand.

[0040] Embodiment 2

[0041] Refer to the attached drawings of the specification, such as Figure 5-Figure 11 As shown, in this embodiment, the main bracket 1 and the extension bracket 2 are retractably connected. Specifically, an extension block 13 is extended from the top of the main bracket 1, and a connecting sleeve 21 is extended from the bottom of the extension bracket 2. When the main bracket 1 and the extension bracket 2 are installed, the extension block 13 is inserted into the connecting sleeve 21, and the connecting sleeve 21 can move along the surface of the extension block 13. There can be a clearance fit between the connecting sleeve 21 and the extension block 13, so that the connecting sleeve 21 needs to use a certain force to pull the extension bracket 2 upward or compress it downward, so that the extension bracket 2 can be appropriately adjusted according to the shape of different people's hands.

[0042] Furthermore, in order to prevent the extension bracket 2 from being separated from the extension block 13 when being pulled upward, as shown in FIG. Fig.11 As shown, a first stopper 131 is fixedly provided on the top of the extension block 13, and a second stopper 211 is fixedly provided on the bottom of the inner surface of the connecting sleeve 21. When the connecting sleeve 21 moves along the extension block 13, the first stopper 131 blocks the second stopper 211 from continuing to move. Specifically, the sum of the transverse lengths of the first stopper 131 and the second stopper 211 is greater than the width inside the connecting sleeve 21. The first stopper 131 and the second stopper 211 can be made of soft silicone material or plastic shell to facilitate the installation of the extension block 13 with the first stopper 131 and the connecting sleeve 21 with the second stopper 211.

[0043] like Fig.11 As shown, a plurality of second protrusions 132 are arranged in parallel on the surface of the extension block 13. When the connecting sleeve 21 moves along the extension block 13, the second stopper 211 passes through the second protrusions 132 in sequence and squeezes the second protrusions 132, so that the height of the extension bracket 2 with the connecting sleeve 21 can be adjusted during the upward pulling process. The material of the second protrusion 132 can be a soft silicone material or a plastic shell. The sum of the transverse lengths of the second protrusion 132 and the second stopper 211 is greater than the width of the inside of the connecting sleeve 21, so that when the second stopper 211 is blocked by the second protrusion 132, the second stopper 211 can squeeze and pass through the second protrusion 132.

[0044] Further, such as Fig.11As shown, the end surface of the second stop block 211 is an arc-shaped surface; the surfaces where the first stop block 131 and the second protrusion 132 contact the second stop block 211 are arc-shaped surfaces, so that the second stop block 211 contacts, squeezes and continues to move during the installation process and normal adjustment process, reducing the influence of the first stop block 131 and the second protrusion 132 on the first stop block 131, thereby reducing the force applied during the graded adjustment of the extension bracket 2, and facilitating the adjustment and use of the tenosynovitis wrist guard.

[0045] In addition, if Figure 5-Figure 7 As shown, compared with the first embodiment, in this embodiment, the number of wrist straps 3 is at least two, one end of the multiple wrist straps 3 is connected as a whole, and a gap is left between two adjacent wrist straps 3. Based on this, a groove is provided on the edge of the main bracket 1, and a plurality of first protrusions 11 are provided in the groove, and a plurality of mounting holes 31 are provided at one end connected with the multiple wrist straps 3 corresponding to the first protrusions 11. When the wrist strap 3 is fixed to the main bracket 1, the first protrusion 11 passes through the mounting hole 31 correspondingly, so that the one end connected with the multiple wrist straps 3 is inserted into the first protrusion 11 and fixed to the main bracket 1. Velcro can be provided at the other end of the wrist strap 3, which passes through and is wrapped around the hollow part of the main bracket 1, so that the other end of the wrist strap 3 is fixedly connected to the main bracket 1.

[0046] like Figure 5-Figure 7 As shown, an inner lining layer 6 is fixedly arranged on the inner side of the main support 1 and the extension support 2, and the material of the inner lining layer 6 can be sponge or silicone material. By setting the inner lining layer 6, when wearing the tendonitis wrist guard, there is a buffer between the human hand and the main support 1 and the extension support 2, avoiding the main support 1 and the extension support 2 from being too hard and causing wear or damage to the hand.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
