[0028] The position of the handle 23 can be adjusted by the handle adjustment component 2, so that the patient can adjust it according to different situations, which is very practical. The support tube 32 can be quickly adjusted by the length adjustment component 3, so that the underarm support frame can meet the needs of patients of different heights. The anti-skid base replacement component 4 can quickly remove the anti-skid base 41 after it is worn out due to long-term use, so as to avoid inconvenience for the patient.

[0029] like Figure 3As shown, the handle adjustment assembly 2 includes two connecting tubes 21, the upper ends of the two connecting tubes 21 are fixedly installed with the left and right parts of the lower end of the underarm support 1, the outer walls of the two connecting tubes 21 are slidably connected with the sliding sleeves 22, and the handle 23 is fixedly installed on the side where the outer walls of the two sliding sleeves 22 are close to each other, and the side where the outer walls of the two connecting tubes 21 are away from each other and the side where the outer walls of the two sliding sleeves 22 are away from each other are provided with a plurality of threaded holes arranged in a linear manner, and the inner walls of a plurality of adjacent threaded holes are threadedly connected with screws 24.

[0030] The two sleeves 22 slide on the outer walls of the two connecting tubes 21 to drive the handle 23 to move to a suitable position for the patient. The two sleeves 22 are fixed by threading them with two corresponding adjacent threaded holes through two screws 24, so that the handle 23 can be fixed in a suitable position.

[0031] like Figure 2 As shown, the length adjustment component 3 includes a fixed sleeve 31, a fixed ring is fixedly installed on the top of the outer wall of the fixed sleeve 31, the left and right parts of the inner wall of the fixed ring overlap with the bottom position of the side away from the outer walls of the two connecting tubes 21, the left and right positions of the top of the outer wall of the fixed sleeve 31 overlap with the bottom position of the side close to the outer walls of the two connecting tubes 21, and the inner wall of the fixed sleeve 31 is slidably connected with a support tube 32.

[0032] The fixing sleeve 31 can be fixed between the two connecting pipes 21 by a fixing ring, and the length of the supporting pipe 32 can be adjusted by sliding the supporting pipe 32 in the inner wall of the fixing sleeve 31 .

[0033] like Figure 2 and Figure 4 As shown, the outer wall of the support tube 32 and the front and rear parts of the outer wall of the fixing sleeve 31 are provided with a plurality of fixing holes 33 arranged in a linear manner, a fixing frame 34 is fixedly installed at the left and right positions of the bottom of the outer wall of the fixing sleeve 31, the fixing sleeve 31 is located in the inner cavity of the fixing frame 34, and the front and rear parts of the inner wall of the fixing frame 34 are fixedly installed with mounting plates 35, and the front and rear sides of the fixing frame 34 are fixedly installed with U-shaped rods 36 that pass through the two mounting plates 35 on the side away from each other, and the ends of the two U-shaped rods 36 that are away from each other are plugged into the inner walls of a plurality of adjacent fixing holes 33.

[0034] The adjusted support tube 32 can be fixed by plugging the two U-shaped plug rods 36 into the corresponding fixing holes 33 .

[0035] like Figure 4 As shown, the sides of the outer walls of the two U-shaped insertion rods 36 that are close to each other are movably sleeved with springs 37, and the ends of the four adjacent springs 37 that are away from each other are fixedly installed at the left and right positions of the front and rear parts of the inner wall of the fixing frame 34, and the ends of the four adjacent springs 37 that are close to each other are fixedly installed at the left and right positions of the side of the mounting plate 35 that is away from each other.

[0036] The four springs 37 can accumulate elastic potential energy when the two U-shaped rods 36 are pulled outward, and the elastic potential energy can be used to quickly fix the support tube 32 through the four adjacent fixing holes 33 after the two U-shaped rods 36 are loosened.

[0037] like Figure 5 As shown, the anti-skid base replacement assembly 4 includes an anti-skid base 41, the inner wall of the anti-skid base 41 is movably connected to the bottom of the outer wall of the support tube 32, and an anti-skid pad is fixedly installed at the lower end of the anti-skid base 41.

[0038] The bottom of the support tube 32 can be slid out from the inner wall of the anti-skid base 41, wherein the anti-skid pad can effectively prevent the patient from slipping when using the underarm support frame.

[0039] like Figure 6 and Figure 7 As shown, storage covers 42 are fixedly installed on the left and right positions of the top of the outer wall of the anti-slip base 41, and insertion holes are provided on the left and right positions of the top of the outer wall of the anti-slip base 41 and the bottom of the outer wall of the support tube 32. A limiting rod 43 that passes through the bottom of the storage cover 42 is fixedly installed on the top of the side where the inner walls of the two storage covers 42 are close to each other, and the ends of the two limiting rods 43 that are close to each other are plugged into the inner walls of the two insertion holes. A through groove 44 is provided on the top of the outer wall of the two limiting rods 43, and a sliding groove 45 is provided on the bottom of the side where the two storage covers 42 are away from each other. The inner walls of the two sliding grooves 45 are slidably connected with adjusting blocks 46, and sliding blocks 47 are fixedly installed on the opposite ends of the two adjusting blocks 46. The tops of the two sliding blocks 47 are inclined structures, and the left and right sides of the two sliding blocks 47 are movably connected with the inner walls of the two through grooves 44. A spring 2 48 is fixedly installed on the ends of the two limiting rods 43 that are away from each other, and the ends of the two springs 2 48 that are away from each other are fixedly connected to the side of the inner walls of the two storage covers 42 that are away from each other.

[0040] By pushing the two adjustment blocks 46, the two adjustment blocks 46 slide on the inner walls of the two slide grooves 45, so that the two adjustment blocks 46 drive the two sliding blocks 47 to move, and the top inclined surface structures of the two sliding blocks 47 cooperate with the inner wall of the through groove 44 to push the two limit rods 43 away from each other, and at the same time, the two springs 48 are squeezed, and the elastic restoring force of the two springs 48 facilitates the two limit rods 43 to reset close to each other.

[0041] like Figure 6 and Figure 7 As shown, the front and rear sides of the inner walls of the two storage covers 42 are fixedly installed with slide rails 49, the opposite sides of four adjacent slide rails 49 are slidably connected with connecting blocks 410, and the opposite ends of the four adjacent connecting blocks 410 are fixedly installed with the front and rear sides of the sliding block 47.

[0042] The four adjacent slide rails 49 and the four adjacent connecting blocks 410 can limit the moving directions of the two sliding blocks 47 .

[0043] The working principle of the utility model is as follows: when the patient needs to adjust the position of the handle 23 when using the underarm support frame, the two screw rods 24 are rotated so that the two sliding sleeves 22 can slide on the outer walls of the two connecting tubes 21. When the two sliding sleeves 22 are moved to the appropriate positions, the two sliding sleeves 22 and the two connecting tubes 21 are fixed together through the threaded connection relationship between the two screw rods 24 and the two adjacent threaded holes, so that the position of the handle 23 can be moved and fixed according to the two sliding sleeves 22.

[0044] When used by patients of different heights, the two U-shaped rods 36 are pulled to disengage the two U-shaped rods 36 from the plug-in relationship with the four adjacent fixing holes 33. The two U-shaped rods 36 simultaneously squeeze the four springs 37 to move the support tube 32 so that the support tube 32 slides on the inner wall of the fixing sleeve 31. When the support tube 32 is extended to an appropriate length, the two U-shaped rods 36 are simultaneously released. The elastic restoring force of the four springs 37 enables the U-shaped rods 36 to be plugged into the corresponding fixing holes 33 to fix the support tube 32.

[0045] When the patient uses the underarm support frame, the anti-slip base 41 will often be worn, and at the same time, the two adjustment blocks 46 will be pushed, so that the two adjustment blocks 46 slide on the inner walls of the two slide grooves 45 and drive the two sliding blocks 47 to move on the two slide rails 49 through the two connecting blocks 410. The inclined surface structure of the two sliding blocks 47 drives the two limit rods 43 to move away from each other through the two through grooves 44, so that the two limit rods 43 squeeze the spring 2 48 at the same time and disengage from the plug-in relationship with the two sockets. Then the anti-slip base 41 can be slid and removed from the bottom of the outer wall of the support tube 32. After replacing the new anti-slip base 41, the two adjustment blocks 46 are loosened, and the elastic potential energy of the two springs 2 48 facilitates the rapid reset of the two limit rods 43 to fix the new anti-slip base 41.

[0046] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
