Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, a spring device capable of adjusting tension comprises a device housing 1, an extension spring 2 is movably mounted on the left side of the device housing 1, a sliding groove 3 is formed above the center of the device housing 1, the sliding groove 3 is communicated with a limiting hole 6, so that when a sliding block 4 slides on the sliding groove 3, a limiting rod 10 on the sliding block 4 can enter the limiting hole 6, thereby fixing the sliding block 4, the sliding block 4 is slidably connected above the sliding groove 3, a hook 5 is fixedly connected on the left side of the extension spring 2, the limiting hole 6 is formed above the center of the device housing 1, the number of the limiting holes 6 is three, the diameter of the limiting hole 6 is equal to that of a movable hole 15, so that the limiting rod 10 can conveniently enter the limiting hole 6 from the movable hole 15 and cannot be blocked, the limiting rod 10 is movably connected on the inner side of the limiting hole 6, a handle 7 is fixedly connected above the limiting rod 10, the limiting rod 10 is conveniently drawn out from the sliding chute 3 and the movable hole 15 through the handle 7, the left side and the right side of the sliding block 4 are respectively provided with the fixed hole 8, the fixed hole 8 is communicated with the movable hole 15, the buckle 14 can enter the fixed hole 8 under the pushing of the supporting spring 12 so as to limit the limiting rod 10, the left side and the right side of the sliding block 4 are respectively and movably provided with the button 9, the inner side of the button 9 is fixedly connected with the push rod, the buckle 14 and the push rod are both positioned in the fixed hole 8, the button 9 can push the buckle 14 into the movable groove 11 through the push rod so as to conveniently draw out the limiting rod 10, the inner side of the center of the sliding block 4 is provided with the movable hole 15, the movable groove 11 is arranged above the center of the limiting rod 10, the inner side of the movable groove 11 is movably connected with the supporting spring 12, the left side and the right side of the supporting spring 12 are respectively and fixedly connected with the limiting plate 13, the limiting plate 13 is movably connected with the limiting rod 10 through the movable groove 11, this makes limiting plate 13 can remove about in gag lever post 10, makes things convenient for supporting spring 12 to pass through limiting plate 13 and drives buckle 14 and remove about, and the right side fixedly connected with buckle 14 of limiting plate 13.

The working principle is that when the tension of the whole device needs to be adjusted, the limiting rod 10 is firstly drawn out from the sliding chute 3 through the handle 7, then the extension spring 2 is pressed or extended, the length of the extension spring 2 in the sliding chute 3 reaches a proper size, then the sliding block 4 is slid to enable the limiting rod 10 to be aligned with the limiting hole 6, then the limiting rod 10 is inserted into the sliding chute 3 through the handle 7 to limit the extension springs 2 with different lengths, the length of the extension spring 2 capable of being stretched is changed, the tension of the whole device is changed, after the limiting rod 10 enters the device shell 1 from the limiting hole 6, the supporting spring 12 drives the buckle 14 to enter the fixing hole 8 through the limiting plate 13, the limiting rod 10 is fixed, the limiting rod 10 is enabled to be fixed while limiting the extension spring 2, and when the limiting rod 10 needs to be drawn out, only the buttons 9 on the left side and the right side of the sliding block 4 need to be pressed, so that the buttons 9 push the buckles 14 to return to the supporting springs 12 through the push rods, the limiting rods 10 can be pulled out of the sliding grooves 3, and the limiting of the extension springs 2 is relieved.

In conclusion, this can adjust tensile spring assembly, through the cooperation of extension spring 2, slider 4, handle 7 and gag lever post 10 use to reach and carry out the tensile effect that adjusts whole device to extension spring 2 and carry out the spacing of different length. When the pulling force of whole device is adjusted to needs, take gag lever post 10 out from spout 3 through handle 7 earlier, press or extension spring 2 after that, make extension spring 2 length in spout 3 reach suitable size, slide block 4 makes gag lever post 10 aim at spacing hole 6 again, rethread handle 7 inserts gag lever post 10 in spout 3, it is spacing to the extension spring 2 of different length to come, make the length change of extension spring 2 that can stretch, thereby change the pulling force of whole device. The effect that the limiting rod 10 is limited to enable the limited part of the extension spring 2 to be fixed is achieved through the matching use of the button 9, the supporting spring 12, the limiting plate 13 and the buckle 14. After the gag lever post 10 enters into device shell 1 from spacing hole 6, supporting spring 12 drives buckle 14 through limiting plate 13 and enters into fixed orifices 8, thereby fix gag lever post 10, make gag lever post 10 carry out spacing when carrying out extension spring 2, self also is fixed, and when gag lever post 10 is taken out to needs, only need press the button 9 of the 4 left and right sides of slider, make button 9 promote buckle 14 through the catch bar and get back to in supporting spring 12, thereby can take out gag lever post 10 from spout 3, relieve the spacing to extension spring 2.
