The first elastic member 17 is kept open under force, so that the mounting segment 26 is installed in the mounting groove 27 under elastic force.

[0045] A circular arc surface 29 is provided at one end of the stopper 14, and a threaded hole 30 is provided at the other end, and a fastener 24 is provided in the threaded hole 30. The fastener 24 is composed of a fastening end 31 and a threaded rod 32, and the threaded rod 32 is installed in cooperation with the threaded hole 30. A through hole 33 is provided in the middle of the arc segment 25 to cooperate with the threaded rod 32. The through hole 33 on the first elastic member 17 is installed in cooperation with the threaded rod 32, and then locked by the fastener 24.

[0046] like Fig.10 As shown, when the arc segment 25 exposed outside the mounting hole 22 on the first elastic member 17 is pressed, the two exposed positions at this time can move toward the surface direction of the tension member 9, so that the arc segment 25 located inside the mounting hole 22 can be driven by force to drive the fastener 24 and the limit member 14 to move, so that the fastener 24 enters the avoidance hole 23, and the limit member 14 slides in the through hole 16, so that the limit member 14 is disengaged from the limit hole 13, and then the tension member 9 can be rotated around the first hinge shaft 10, and the limit member 14 can be inserted into the limit holes 13 at different positions.

[0047] The second adjustment mechanism 4 is provided with a tension plate 34 and an adjustment assembly 35 arranged on both sides of the tension plate 34. The adjustment assembly 35 is provided with a second adjustment seat 36, a second elastic member 37, a locking member 38 and a retaining member 39. The second elastic member 37 is mounted on the second adjustment seat 36, the locking member 38 is hinged on the second adjustment seat 36 through a second hinge shaft 40, the retaining member 39 is hinged on the second adjustment seat 36 through a third hinge shaft 41, and the tension plate 34 is mounted on the third hinge shaft 41. The locking member 38 is arranged in the middle of the second elastic member 37, and the retaining member 39 is provided with a plurality of retaining protrusions 42, and a plurality of retaining areas 43 are formed between the retaining protrusions 42 and the retaining protrusions 42, and the locking member 38 extends into the retaining area 43.

[0048] The second adjustment seat 36 is composed of a transverse section 44 and a vertical section 45, wherein the transverse section 44 is arranged perpendicular to the vertical section 45. The transverse section 44 is provided with a corrugated groove 46 and an avoidance arc surface 47, and the avoidance arc surface 47 is used to avoid the rotation of the locking protrusion 48. The vertical section 45 is provided with a second hinge hole 49 matched with the second hinge shaft 40 and a third hinge hole 50 matched with the third hinge shaft 41.

[0049] The second elastic member 37 is composed of a corrugated section 51 and a symmetrically arranged horizontal section 52, an inclined section 53, a bent section 54 and a curved section 55. The curved section 55 is arranged in an arc shape, and the bent section 54 is arranged in a "V" shape. The inclined section 53 and the curved section 55 are connected by the bent section 54. The corrugated section 51 is installed in cooperation with the corrugated groove 46. The inclined section 53 and the horizontal section 52 are connected by an arc portion 56. The curved sections 55 and the curved sections 55 form a second elastic area 57. The locking member 38 is arranged in the second elastic area 57. When the locking member 38 swings left and right, it will exert pressure on the second elastic member 37, so that the inclined section 53 is subjected to force and the arc portion 56 is deformed.

[0050] The locking member 38 is composed of a hinge end 58 and a locking end 59. A fourth hinge hole 61 is provided in the middle of the hinge end 58 to cooperate with the second hinge shaft 60. The locking end 59 extends into the holding area 43. The locking member 38 is provided with symmetrically arranged inclined surfaces 62, which contact the curved section 55. The hinge end 58 is provided with a notch 63 to cooperate with the bent section 54. The locking member 38 gradually narrows from the hinge end 58 to the locking end 59, and a contact arc surface 64 is provided on the locking end 59 to contact the first retaining step 65 and the second retaining step 66.

[0051] A symmetrically arranged locking protrusion 48 is also provided on the hinged end 58 . The locking protrusion 48 is located between the bending section 54 and the horizontal section 52 . The locking protrusion 48 is used to cooperate with the bending section 54 to limit the swing angle and position of the locking member 38 .

[0052] A fifth hinge hole 68 cooperating with the third hinge shaft 67 is provided in the middle of the retaining member 39, and the retaining protrusion 42 is composed of a first retaining step 65 and a second retaining step 66. The height of the first retaining step 65 is lower than the height of the second retaining step 66, and the second retaining step 66 is in the middle position of the first retaining step 65. A retaining positioning area 69 is formed between the first retaining step 65 and the second retaining step 66.

[0053] Since the main body 70 of the retaining member 39 is in a disc shape, the diameter of the main body 70 is r1, the diameter of the first retaining step 65 is r2, and the diameter of the second retaining step 66 is r3, r1<r2<r3. The locking member 38 makes the contact arc surface 64 cooperate with the column only when it is in the retaining area 43. When the contact arc surface 64 is in the positioning area 69, the locking member 38 will be kept in an inclined state as shown in FIG8, and the second elastic member 37 in the figure is in the installation state when the locking member 38 is in a vertical state.

[0054] In order to prevent the angle of the tension plate 34 from changing after the tension plate 34 is rotated, a torsion spring (not shown in the figure) is provided on the third hinge shaft 67, one end of the torsion spring is mounted on the retaining member 39, and the other end is mounted on the tension plate 34. When the tension plate 34 is bent, the locking member 38 is placed in the positioning area 69, the position of the retaining member 39 is locked, and the torsion spring is kept under force, thereby limiting the position of the tension plate 34.

[0055] The tension plate 34 is provided with an arc-shaped surface 67, and positioning posts 71 are provided on both sides of the arc-shaped surface 67. The positioning posts 71 can limit the position of the yarn. The tension plate 34 is moved to drive the retaining member 39 to rotate through the third hinge shaft 41, and push the locking member 38 to keep the second elastic member 37 deformed by force, limit the position of the locking member 38, and limit the position of the retaining member 39 and the tension plate 34 through the locking member 38.

[0056] When the tension plate 34 is working, Figure 4 and 8 As shown, Figure 4 The locking member 38 is in a vertical state, and the locking end 59 is in the holding area 43. Assuming that the state of the tension plate 34 at this time is as follows Figure 2 As shown, when the tension plate 34 is rotated in the direction of F1, Figure 4The retaining protrusion 42 (M) will push the locking member 38 to rotate around the second hinge shaft 40, and then the first retaining step 65 will push the locking end 59 first, so that the second elastic member 37 is deformed under force, and then the second retaining step 66 will push the locking end 59, so that the contact arc surface 64 is in the positioning area 69 at N. At this time, the torsion spring has been deformed and elastic potential energy has been generated. However, the locking member 38 in the inclined state will block the retaining protrusion 42 and the retaining member 39 cannot be reset. Therefore, the angle limitation of the tension plate 34 can be achieved, thereby adjusting the tension of all yarns.

[0057] When resetting, it is only necessary to rotate the retaining member 39 in the direction of F1 again so that the locking member 38 reaches the position as shown in FIG. Figure 8 It only needs to be within the holding area 43 at the middle Y.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
