[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present utility model.

[0018] As Figures 1-4 shown, the present utility model provides a technical scheme: a portable spring stick for bodybuilding, including strong spring 1, the left end of strong spring 1 is fixedly connected with end cover 3, and the right end of strong spring 1 is equipped with handle 2, handle 2 is circular tubular, the right end of strong spring 1 is connected with connecting rod 4, and connecting rod 4 is inserted in handle 2.

[0019] According to the overall structure of the device, one hand holds handle 2 and shakes strong spring 1 to carry out bodybuilding exercise.

[0020] As Figure 1 shown, silica gel sleeve 7 is sleeved on the outside of handle 2, and anti-skid lines are formed on the surface of silica gel sleeve 7.

[0021] Silica gel sleeve 7 improves the comfort when holding handle 2, enhances the friction, and prevents hand from slipping.

[0022] As Figure 1 , 2As shown, the outer side of the handle 2 is sleeved with two hoops 5, which are respectively located on the left and right sides of the silica gel sleeve 7. The strong spring 1 and the connecting rod 4 are welded. The outer side of the connecting position of the strong spring 1 and the handle 2 is sleeved with a sleeve 6, and the sleeve 6 is provided with an opening hole matched with the hoop 5.

[0023] The strong spring 1 and the handle 2 are connected by welding, which prevents the strong spring 1 from falling off, and the sleeve 6 and the hoop 5 strengthen the connection between the connecting rod 4 and the handle 2.

[0024] As shown in Figure 2 , 3 , the handle 2 is internally provided with a storage bag 9. The bottom of the storage bag 9 is fixedly connected with the connecting rod 4, and the bag opening is sewn with a zipper 11 and a lifting rope 10.

[0025] The spring stick is stored in the storage bag 9, which isolates the spring stick from the outside world, prevents foreign matters from being clamped in the strong spring 1, and facilitates carrying the spring stick.

[0026] As shown in Figure 2 , the left end of the handle 2 is provided with a screw cap 8. The inner wall of the handle 2 is provided with an internal thread, and the screw cap 8 is provided with an external thread matched with the internal thread.

[0027] The inner cavity of the handle 2 is closed by the screw cap 8, which prevents the storage bag 9 from falling out, and can quickly open the inner cavity of the handle 2 to take out the storage bag 9.

[0028] Working principle: when in use, hold the handle 2 and shake the spring stick for bodybuilding. The silica gel sleeve 7 increases the friction force to prevent the spring stick from falling off. When going out, unscrew the screw cap 8, pull out the storage bag 9 from the inner cavity of the handle 2, and turn the sleeve outward to the spring stick, so as to store the spring stick. Then pull up the zipper 11 and carry it through the lifting rope 10.
