[0006] An internal thread is arranged in the adjusting cavity. After installation, the adjusting bolt is screwed on the internal thread and fixed in the adjusting cavity.

[0007] The middle part of the adjusting bolt is hollow and provided with a hexagonal inner groove.

[0008] A washer is arranged on the outer side of the slider, and after assembly, the washer is placed in the gap between the slider and the rod body.

[0009] A recessed portion for mounting the washer is arranged on the outer wall of the sliding block, and the washer is placed in the recessed portion.

[0010] The upper end of the rod body is open to be provided with an opening, and a top cover is installed in the opening.

[0011] The end of the handheld part is threadedly connected with a ring-shaped bottom cover.

[0012] The bottom end of the hand-held part is recessed toward the middle to form a connecting part, a step surface is formed between the connecting part and the hand-held part, and the side wall of the connecting part and the inner side of the bottom cover are provided with corresponding threads. After installation, the top surface of the bottom cover is against the step surface.

[0013] The beneficial effects of the utility model are as follows: a slider is arranged in the bat body, and the bat body and the slider are connected by an elastic rope. When the bat is swung, the slider slides out along the length direction of the bat, simulating the feel of the bat and the change of the center of gravity when hitting the ball. The training bat does not require the trainee to actually hit the softball, and the trainee can feel the change of the center of gravity and the feel similar to hitting the ball. It is very friendly to some beginners who have never been exposed to softball and improves the training effect. At the same time, when the training bat is swung, the center of gravity of the bat is farther and farther away from the palm, which can train the arm strength of the user and further improve the training effect.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0021] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0022] Reference Figures 1 to 5A softball training bat with a movable center of gravity comprises a bat body 1, wherein the bat body 1 comprises a striking portion 11 at the top and a hand-held portion 12 located below the striking portion 11, wherein the striking portion 11 is hollow to form a sliding cavity 13, wherein a slider 2 which can slide along the length direction of the bat body 1 is installed in the sliding cavity 13, wherein the lower end of the slider 2 is connected to the bottom end of the hand-held portion 12 through an elastic rope 3, wherein the hand-held portion is hollow to form an adjusting cavity 16, wherein an adjusting bolt 4 is installed in the adjusting cavity 16, wherein the upper end of the elastic rope 3 is fixed on a connecting bolt 5, wherein the connecting bolt 5 is threadedly connected to the bottom end of the slider 2, wherein a threaded interface is provided at the lower end of the slider, and wherein the connecting bolt 4 is threadedly connected to the bottom end of the slider 2. Located in the threaded interface, the lower end of the elastic cord 3 is fixed to the through hole on the side wall of the adjusting bolt 4; the utility model is provided with a slider in the stick body, and the stick body and the slider are connected by the elastic cord, and the slider slides out along the length direction of the stick when the stick is swung, simulating the feel and change of the center of gravity of the stick when hitting the ball. This training stick does not require the trainee to actually hit the softball to feel the change of the center of gravity and the feel similar to hitting the ball, which is very friendly to some beginners who have not been exposed to softball and improves the training effect; at the same time, when the training stick is swung, the center of gravity of the stick is farther and farther away from the palm, which can train the user's arm strength and further improve the training effect.

[0023] The adjusting cavity 16 is provided with an internal thread. After installation, the adjusting bolt 4 is screwed on the internal thread and fixed in the adjusting cavity 16. The adjusting bolt 4 is hollow in the middle and provided with a hexagonal socket. After the training stick is used for a period of time, the elastic rope will be stretched, resulting in a decrease in the tension provided, so that the slider can slide freely in the stick body. Based on this reality, the present embodiment provides an adjusting cavity and an adjusting bolt in the handheld part. One end of the adjusting bolt is connected to the elastic rope. When the elastic force of the elastic rope decreases, the elastic rope can be tightened again by screwing the adjusting bolt to maintain a certain elastic force, thereby extending the service life of the training stick.

[0024] A washer 21 is provided on the outside of the slider 2. After assembly, the washer 21 is placed in the gap between the slider 2 and the rod body 1. A recessed portion for installing the washer 21 is provided on the outer wall of the slider 2, and the washer 21 is placed in the recessed portion. By providing a recessed portion on the outer wall of the slider, the washer is inserted into the recessed portion to fix its position and prevent it from moving. In this embodiment, the washer is made of rubber, and other materials such as silicone can also be used. When in use, lubricating oil is applied to the inner wall of the sliding cavity so that the washer can slide along the length direction of the rod body close to the inner wall of the sliding cavity.

[0025] The upper end of the rod body 1 is open to form an opening 14, and a top cover 4 is installed in the opening 14; during assembly, the slider is filled into the sliding cavity from the opening at the upper end of the rod body.

[0026] The end of the hand-held part 12 is threadedly connected to a ring-shaped bottom cover 5; the bottom end of the hand-held part 12 is recessed toward the middle to form a connecting part 15, and a step surface is formed between the connecting part 15 and the hand-held part 12. The side wall of the connecting part 15 and the inner side of the bottom cover 5 are provided with corresponding threads. After installation, the top surface of the bottom cover 5 rests on the step surface.
