[0024] Example 1, as shown in the attached document Figures 1-5 As shown, this application includes a connecting structure 3, which connects two protective boxes 1. A protective plate 101 is provided on the protective box 1. Two fixing seats 202 are provided inside the protective box 1. One of the fixing seats 202 is slidably connected inside the protective box 1 and is fixedly connected to a gripping structure. A plurality of elastic elements 203 are provided between the two fixing seats 202. The protective box 1 and the protective plate 101 cooperate to protect the elastic elements 203.

[0025] During tensile training, the elastic element 203 is constantly subjected to stretching and contraction forces. Prolonged use or improper use may cause the elastic element 203 to break or fall off. Once the elastic element 203 breaks or falls off, the impact force it generates may cause physical injury to the user. The physical protective structure formed by the protective plate 101 and the protective box 1 can wrap around potentially dangerous components such as the elastic element 203. Even if the elastic element 203 has a problem, it will be blocked, reducing direct contact with the user, thereby greatly reducing the risk of injury to the user and allowing the user to train with more peace of mind.

[0026] Furthermore, the grip structure includes a connecting frame 201 fixedly connected to one of the fixed seats 202. The connecting frame 201 is slidably connected to the inner wall of the protective box 1. When the connecting frame 201 is subjected to force and moves outward from the protective box 1, it can drive the fixed seat 202 connected to it to move, thereby stretching the elastic element 203. The elastic element 203 deforms during the stretching process. According to Hooke's Law, the deformation will generate a counterforce opposite to the stretching direction. This counterforce becomes the resistance that the user needs to overcome when performing tensile training. By continuously overcoming this resistance, the user can exercise muscles and achieve the training effect of increasing strength.

[0027] The connecting frame 201 is provided with a scale. In the training process, it is very important to know the intensity and progress of the training for formulating a reasonable training plan. The scale on the connecting frame 201 provides an intuitive reference standard for the user. The user can accurately know the moving distance of the connecting frame 201 by observing the change of the scale. The length of the moving distance is related to the stretching degree of the elastic member 203, and the stretching degree of the elastic member 203 determines the size of the resistance. Therefore, by observing the scale, the user can indirectly know the size of the resistance he bears in the training process, and then evaluate the training intensity. At the same time, by recording the moving scale of the connecting frame 201 in different time periods, the user can clearly see the change of his training progress, which provides a basis for adjusting the training plan, so that the training is more scientific and effective.

[0028] Further, the end of the connecting frame 201 away from the fixed seat 202 penetrates out of the protective box 1 and is fixedly connected with a handle 2. The handle 2 is provided for the user to provide a force point for the hand, which is convenient for the user to operate the hand.

[0029] Further, the elastic member 203 is one or both of a spring and an elastic rope. The spring and the elastic rope have different elastic characteristics. The spring has relatively stable elasticity and can provide relatively constant resistance, which is suitable for training with stable strength. The elasticity of the elastic rope is relatively soft, and has a certain stretching range. The change of the resistance in the stretching process is relatively flat, which is suitable for some flexible and diversified training actions. The user can select different elastic members 203 according to his training target, physical condition and personal preference.

[0030] Further, the other fixed seat 202 is detachably arranged in the protective box 1, and the other fixed seat 202 is installed in the protective box 1 by a bolt. The bolt connection makes the fixed seat 202 also detachable, which is convenient for maintenance.

[0031] In embodiment 2, the tension training device provided in embodiment 1 is further optimized. Specifically, as shown in Figure 4 The elastic member 203 is fixedly connected between the two fixed seats 202, which can keep the elastic member 203 in a stable state during stretching.

[0032] In the embodiment 3, the two fixed seats 202 are provided with a plurality of clamping grooves 204, the two ends of the elastic member 203 are fixedly connected with clamping seats 205, the side of the clamping seat 205 away from the elastic member 203 is fixedly connected with two clamping claws 206, and the two clamping claws 206 are clamped with the inner walls of the clamping grooves 204, so that the elastic member 203 is detachably arranged. Specifically, the two clamping claws 206 are pulled outward after being pushed to be close to each other, so that the clamping claws 206 are separated from the clamping grooves 204, and then the elastic member 203 is taken off. After the clamping claws 206 are inserted into the clamping grooves 204, the clamping claws 206 are clamped, so that the elastic member 203 is installed. The number of the elastic members 203 can be increased or decreased according to the training condition, and the aged or damaged elastic members 203 can be conveniently replaced.

[0033] In the embodiment 4, the protective plate 101 and the protective box 1 are detachably arranged, and the protective plate 101 and the protective box 1 are fixed by bolts. After the bolts are unscrewed, the protective plate 101 can be detached, and the protective plate 101 and the protective box 1 can be transparent, so that the use can be observed.

[0034] Further, the connecting structure 3 comprises a first connecting plate 301 fixedly installed on one of the protective boxes 1 and two connecting seats 302 fixedly installed on the other protective box 1. The two connecting seats 302 are fixedly connected with a connecting shaft 304. The side surface of the first connecting plate 301 is provided with a groove 303, and the groove 303 is also fixedly connected with the connecting shaft 304. The outer surfaces of the two connecting shafts 304 are sleeved with a second connecting plate 305, so that the first connecting plate 301 and the connecting seat 302 can rotate, and then the two protective boxes 1 can be folded. The folded state is shown in Figure 6 At this time, the overall length is shortened, the carrying is facilitated, and the positions of the two handles 2 do not coincide. The part of the user's thumb connected with the palm can be pressed on the top of the handle 2 at the high position, and the remaining four fingers can be hooked on the handle 2 at the low position and pulled upward, so that the grip strength training can be performed. The present application can realize different training functions in different states, and the functionality of the present application is improved. Figure 1 In the state, the user holds the two handles 2 with both hands and performs the stretching operation, so that the chest, biceps and triceps can be trained.

[0035] Further, the two sides of the second connecting plate 305 are arc-shaped, and the sides of the first connecting plate 301 and the connecting seat 302 away from the protective box 1 are also arc-shaped. The arc-shaped arrangement reduces the interference between the components and facilitates the rotation.
