[0027] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, an adjustable handle for a tensioner includes a handle body 1, a grip portion 2 for holding is formed at one end of the handle body 1, a connecting portion 3 is formed at the other end of the handle body 1, an end cover 4 is installed on the connecting portion 3, and an installation cavity 5 for one end of an elastic rope 6 to pass through is formed between the end cover 4 and the connecting portion 3. An inlet end 7 is opened at one end of the installation cavity 5, and an outlet end 8 is opened at the other end of the installation cavity 5. One end of the elastic rope 6 enters into the installation cavity 5 from the inlet end 7, and then passes out from the outlet end 8. A rotatable adjusting member 9 is provided on one side of the installation cavity 5, and a fixing portion 10 for limiting the movement of the elastic rope 6 is formed at one end of the adjusting member 9, so as to adjust the length of the elastic rope 6.

[0029] Through the design of the adjusting piece, the utility model makes it possible, during actual use, to rotate the adjusting piece 9 so that the fixing portion 10 is away from the end face of the elastic cord 6, thereby releasing the fixation of the elastic cord 6. At this time, the length of the elastic cord 6 can be freely adjusted. After the adjustment is completed, the adjusting piece 9 is rotated in the opposite direction so that the fixing portion 10 is close to and abuts against the end face of the elastic cord 6, thereby limiting the movement of the elastic cord 6, thereby achieving a fixing effect. The adjusting structure is simple and easy to operate. The length of the elastic cord can be quickly adjusted during use, and is suitable for different groups of people.

[0030] A lower rotating column 11 is arranged in the connecting portion 3, an upper rotating column 12 is arranged in the end cover 4, a rotating hole 13 for inserting the rotating column is opened at the other end of the adjusting member 9, and the adjusting member 9 is installed on the outer periphery of the rotating column through the rotating hole 13 so as to be rotatable. The installation structure is simple and easy to assemble and disassemble.

[0031] In order to keep the fixing portion 10 of the adjusting member 9 against the end surface of the elastic cord 6 in the absence of external force, so as to achieve the function of fixing the position of the elastic cord 6, the present invention adopts one of the following technical solutions to achieve the effect: Figure 2The upper and lower end surfaces of the adjusting member 9 are respectively provided with arc-shaped clamping blocks 14, the end cover 4 is provided with an upper clamping portion 15, and the upper clamping portion 15 is provided with an upper clamping groove 16 for the arc-shaped clamping block 14 to be clamped in, the connecting portion 3 is provided with a lower clamping portion 17, and the lower clamping portion 17 is provided with a lower clamping groove 18 for the arc-shaped clamping block 14 to be clamped in, combined with Figure 3 When the adjusting member 9 rotates to the left, the arc-shaped block 14 will be inserted into the upper and lower slots, thereby limiting the rotation of the adjusting member 9. In the absence of external force, the fixing portion 10 of the adjusting member 9 can be kept against the end surface of the elastic cord 6, thereby achieving the effect of fixing the position of the elastic cord 6. When the length of the elastic cord 6 needs to be adjusted, the elastic cord 6 can be adjusted by combining the arc-shaped block 14 with the upper and lower slots. Figure 3 By rotating the adjusting member 9 to the right, the arc-shaped block can slide out of the slot.

[0032] In actual use, other equivalent structures may be used as a substitute to achieve the same technical effect, such as providing a torsion spring and relying on the elastic force of the spring to keep the fixed portion 10 of the adjustment member 9 against the end surface of the elastic rope 6.

[0033] Furthermore, the utility model relies on the fixing portion 10 to abut against the end surface of the elastic cord 6 to keep the elastic cord 6 in place. Therefore, in the actual installation process, the handle can be adapted to elastic cords 6 of different thicknesses and shapes, and has a wide range of applications.

[0034] Combination Figure 3 and Figure 4 The other end of the adjusting member 9 is formed with a limiting portion 19, which can limit the maximum rotation angle of the adjusting member 9 to the left or right to prevent excessive rotation and thus cause structural damage.

[0035] A lever ear 20 is formed at one end of the fixing portion 10 , and the lever ear 20 extends to the outside of the outlet end 8 . In actual use, the position of the adjusting member 9 can be rotated by operating the lever ear 20 , which is conducive to improving the convenience of operation.

[0036] The other end of the fixing portion 10 is formed with a locking portion 21 for abutting against the end face of the elastic cord 6. The technical solution adopts the design of the locking portion 21 so that when the fixing portion 10 abuts against the end face of the elastic cord 6, the locking portion 21 simultaneously abuts against the end face of the elastic cord 6 and causes it to elastically deform. The elastic cord 6 is partially bent at this point, which can further fix the position of the elastic cord 6 to prevent it from moving during use.

[0037] Look specifically Figure 3 The side of the fixing portion 10 is formed with a plurality of anti-slip strips 22. When the fixing portion 10 is against the end surface of the elastic cord 6, the anti-slip strips 22 can increase the friction between the contact surfaces of the two, thereby further effectively preventing the fixing portion 10 from moving during use.

[0038] Combination Figure 2 and Figure 3 Two arc-shaped limiting plates 23 are arranged between the end cover 4 and the connecting part 3, and the installation cavity 5 is formed between the two arc-shaped limiting plates 23. One end of the elastic rope 6 is bent and penetrated into the installation cavity 5. The inner wall of the outlet end 8 is formed with a limiting plate 24 for the elastic rope 6 to abut against, thereby increasing the contact area between the elastic rope 6 and the elastic rope 6, so that the elastic rope 6 is clamped between the fixing part 10 and the two end surfaces of the limiting plate 24 to prevent it from sliding.

[0039] The connecting portion 3 is provided with a plurality of connecting columns 25 , and the end cover 4 is provided with a plurality of connecting columns 26 . The connecting columns 25 and 26 are respectively provided with fastening holes 27 for inserting fasteners, so as to realize a detachable connection between the end cover 4 and the connecting portion 3 .

[0040] A handle hole 28 is formed in the handle body 1 , and a grip groove 29 is formed on the inner wall of the grip portion 2 .
