[0026] Embodiment 1:

[0027] As attached Figure 1 To Attachment Figure 6 As shown:

[0028] The utility model provides a novel stretcher, comprising a bed board 1, wherein a cotton pad 101 is fixedly arranged on the upper rear portion of the bed board 1; a display screen 102 is fixedly arranged on the front end of the top of the bed board 1; two groups of side guide columns 2 are fixedly arranged on the front of both sides of the top of the bed board 1; roller sliding frames 202 are slidably arranged on the inner sides of the side guide columns 2, two groups of pedal rods 201 are fixedly arranged between the two groups of roller sliding frames 202, two groups of connecting U rings 207 are fixedly arranged on both ends of the rear sides of the two groups of pedal rods 201, connecting cables 208 are slidably arranged on the outside of the connecting U rings 207, and the rear end of the connecting cable 208 is connected with a tension spring 3; a connecting rope 4 is connected to the outside of the tension spring 3, and a locking frame 5 is passed through the outside of the connecting rope 4.

[0029] A receiving groove 103 is provided above the bed board 1 between the side guide pillars 2 on both sides, and the pedal rod 201 and the connecting U ring 207 can both be lowered into the receiving groove 103 .

[0030] Among them, a spring rod 203 is fixedly set in the middle of the roller sliding frame 202, a fixed slider 204 is slidably set outside the spring rod 203, and a fixed wheel 205 is rotatably set in the middle of the upper and lower sides of the fixed slider 204; a wheel receiving groove 206 is opened on the inner wall of the side guide column 2, and two groups of fixed wheels 205 on the same side can be accommodated in the wheel receiving groove 206.

[0031] The spring rod 203 is provided with a spring on its outer sleeve for opening the fixed slider 204 and pushing the embedded wheel 205 into the wheel receiving groove 206 .

[0032] Wherein, both ends of the tension spring 3 are fixedly provided with connecting piles 301, and the connecting piles 301 are of a threaded sleeve structure. The ends of the connecting cable 208 and the connecting rope 4 are both provided with threaded connectors to be threadedly connected and fixed to the connecting piles 301.

[0033] A pressure sensor 501 is fixedly arranged inside the locking frame 5 , a sending bin 502 is fixedly arranged at the bottom of the locking frame 5 , a locking block 503 is fixedly arranged on the top of the pressure sensor 501 , and a handle 504 is fixedly arranged outside the locking frame 5 .

[0034] The connecting rope 4 passes through the locking block 503 and is fixed in the locking block 503 with the top screw.

[0035] like Figure 1-6 As shown, the tension spring 3 is replaced according to the needs of exercise, and the connecting pile 301 is connected by threads and can be disassembled by reverse rotation;

[0036] The tension spring 3 is pre-made into 10KG, 15KG, 20KG, 25KG, and 30KG, which can be increased as needed, with each higher level increasing by 5KG;

[0037] When standing and stretching, the user directly steps on the pedal bar 201, inserts the pedal bar 201 into the receiving groove 103, holds the two sets of handles 504, and then pulls the handles 504. The stretching force will pull the tension spring 3 apart, so as to exercise. During the stretching process, the connecting rope 4 will pull the locking block 503 to apply pressure to the pressure sensor 501. The pressure sensor 501 calculates the degree of force applied to the pull apart, and then feeds back to the display screen 102. The reading can be used to calculate whether the exercise is normal.

[0038] If the connecting rope 4 is long, the top screw outside the locking block 503 can be loosened, and then the connecting rope 4 can be pulled to make adjustments, and then fixed with the top screw.

[0039] Embodiment 2:

[0040] On the basis of Example 1, when lying down and stretching, the footrest rod 201 is pulled up. During the process of the side guide column 2 rising, the spring outside the spring rod 203 exerts a force on the fixed slider 204 to push the embedded wheel 205 into the wheel receiving groove 206. The side of the embedded wheel 205 fits the wheel receiving groove 206 to provide a horizontal force.

[0041] Then, the user lies on the cotton pad 101 and pulls the handle 504 to perform horizontal stretching training;

[0042] The connection point of the connecting cable 208 will slide naturally outside the connecting U ring 207 due to gravity, and adjust the direction of action.

[0043] The specific usage and function of this embodiment are as follows:

[0044] In the utility model, when in use, the tension spring 3 is replaced according to the needs of exercise, and the connecting pile 301 is connected by a thread and can be disassembled by reverse rotation;

[0045] When standing and stretching, the user directly steps on the pedal bar 201, inserts the pedal bar 201 into the receiving groove 103, holds the two sets of handles 504, and then pulls the handles 504. The stretching force will pull the tension spring 3 apart, so as to exercise. During the stretching process, the connecting rope 4 will pull the locking block 503 to apply pressure to the pressure sensor 501. The pressure sensor 501 calculates the degree of force applied to the pull apart, and then feeds back to the display screen 102. The reading can be used to calculate whether the exercise is normal.

[0046] If the connecting rope 4 is long, you can loosen the top screw outside the locking block 503, then pull the connecting rope 4 to adjust it, and then fix it with the top screw;

[0047] When stretching while lying down, pull up the footrest rod 201. During the rising process of the side guide column 2, the spring outside the spring rod 203 applies force to the fixed slider 204 to push the embedded wheel 205 into the wheel receiving groove 206. The side of the embedded wheel 205 fits the wheel receiving groove 206 to provide a horizontal force. Then, lie down on the cotton pad 101 and pull the handle 504 to perform stretching training in this direction.
