[0025] Referring to Figure 1 , the present utility model provides a new type of tensioner, which includes a handle 1 for holding, a positioning buckle 2 for fixing an elastic cord 3, and a plurality of elastic cords 3. There are two handles 1, and the handle 1 is provided with a positioning cavity 11 with a side opening. A plurality of positioning holes 12 are provided on the upper and lower surfaces of the positioning cavity 11, and the positioning holes 12 penetrate through the surface of the handle 1; as Figure 2 shown, the positioning buckle 2 is inserted into the positioning cavity 11. The positioning buckle 2 is provided with two pressing plates 21 and a fixing hole 22. The pressing plate 21 is provided with a positioning boss 23, and the positioning boss 23 is clamped in the positioning hole 12; the end of the elastic cord 3 is fixed in the fixing hole 22. When the user takes or places the spring of this product, the user applies a pressing force to the two positioning bosses 23 on the positioning buckle 2, so that the positioning bosses 23 retract into the positioning cavity 11, and at the same time, by pulling the elastic cord 3, the positioning buckle 2 can be removed from the handle 1. It should be noted that the pressing piece in this product is made of a material with a certain deformation ability. Compared with the traditional tensioner, in this product, the control point of the positioning buckle 2 is transferred to the upper and lower side surfaces of the handle 1, and the stress area is increased through the positioning boss 23, which facilitates the user's operation of the positioning buckle 2 and further facilitates the taking and placing of the elastic cord 3.

[0026] As Figure 3 shown, the positioning buckle 2 is U-shaped. A connecting plate 24 is provided between the two pressing plates 21, and the fixing hole 22 is provided on the connecting plate 24. The connecting plate 24 is preferably arc-shaped. While improving the aesthetic feeling, the arc-shaped connecting plate 24 can withstand a greater pulling force, and at the same time, an annular inclined edge 221 is provided inside the fixing hole 22.

[0027] AsFigure 2 As shown, guide grooves 13 that slope outward are provided on the upper and lower cavity walls of the positioning cavity 11. The depth of the guide grooves 13 increases from inside to outside. The higher end of the position of the guide grooves 13 intersects with the positioning holes 12. After disengaging from the positioning holes 12, the positioning bosses 23 can slide outwards along the guide grooves 13, thus facilitating the user to remove the positioning buckle 2.

[0028] As Figure 2 shown, the positioning holes 12 on the upper and lower surfaces of the positioning cavity 11 are symmetrically distributed. A plurality of partition plates 14 are provided in the positioning cavity 11, and the positioning holes 12 are distributed between the partition plates 14.

[0029] As Figure 4 shown, a clamping block 31 is provided at the end of the elastic cord 3. The clamping block 31 can also be formed by tying a knot in the elastic cord itself. The clamping block 31 is provided between the two pressing plates 21, and the clamping block 31 is used to abut against the fixing hole 22.

[0030] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
