Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-7 , an embodiment provided by the utility model: an adjustable softball thrower, comprising a base 1;

[0022] A lifting assembly 2 is installed at the upper end of the base 1, a slide rail 4 is installed at the upper end of the lifting assembly 2, a slide sleeve 5 is movably installed in the slide rail 4, a slide groove 6 is symmetrically opened at the lower end of the slide sleeve 5, a handle 7 is installed at the lower end of the slide sleeve 5, and a slider 8 is symmetrically installed at the upper end of the handle 7. Two groups of sliders 8 slide in the two groups of slide grooves 6. A gravity adjustment assembly is installed on the left side of the upper end of the handle 7 and the lifting assembly 2. The device drives the slide sleeve 5 to slide in the slide rail 4 by holding the handle 7, and increases the load force of pulling the handle 7 and the slide sleeve 5 through the gravity adjustment assembly;

[0023] Furthermore, the gravity adjustment component includes a pull rope 9, which is fixedly installed on the left side of the upper end of the handle 7. A fixed frame 10 is installed on the lifting component 2. The left side of the lower end of the fixed frame 10 is movably sleeved on the lower end of the lifting component 2. A connecting rod 11 is installed at the lower end of the pull rope 9. Multiple groups of second counterweights 12 are arranged in the fixed frame 10. The lower end of the connecting rod 11 is inserted into the multiple groups of second counterweights 12. Through holes 13 are opened on the lower end of the connecting rod 11 and the multiple groups of second counterweights 12. Insert rods 14 are inserted in the through holes 13. This structure inserts the insert rod 14 into the through holes 13. When the handle 7 is pulled to drive the sliding sleeve 5 to slide, the connecting rod 11 and the multiple groups of second counterweights 12 are lifted up through the pull rope 9, so as to exercise the explosive power when throwing a softball.

[0024] Furthermore, a first counterweight block 3 is installed at the connection between the lifting component 2 and the base 1, and the first counterweight block 3 is fitted with the upper side of the base 1. This structure is installed at the connection between the lifting component 2 and the base 1 through the first counterweight block 3, thereby increasing the stability of the support of the base 1 and the lifting component 2 to the slide rail 4.

[0025] Furthermore, the lifting assembly 2 includes a sleeve rod 15, which is fixedly mounted on the upper end of the base 1, and a support rod 16 is movably inserted in the sleeve rod 15. A gear 17 is rotatably installed in the left side of the upper end of the sleeve rod 15, a tooth groove 18 is provided on the left side of the support rod 16, and the right side of the gear 17 is meshed with the tooth groove 18. A knob 19 is fixedly mounted on the front side of the gear 17, a movable groove 20 is provided in the knob 19, a spring 21 is installed in the movable groove 20, and a limit block 22 is installed in the movable groove 20. A plurality of groups of limit grooves 23 are provided in a ring on the front side of the upper end of the sleeve rod 15, and a pull rod 24 is installed at the front end of the limit block 22. This structure drives the gear 17 to rotate on the tooth groove 18 by rotating the knob 19, so that the support rod 16 can be lifted up and down from the sleeve rod 15, and the position height of the slide rail 4 can be adjusted, and the knob 19 and the gear 17 are limited and fixed by inserting the limit block 22 in the limit groove 23.

[0026] Furthermore, a thread is provided on the outer wall at the rear end of the pull rod 24, and the pull rod 24 is inserted into the knob 19. The joint between the pull rod 24 and the knob 19 is adapted to the thread on the surface of the pull rod 24. When this structure pulls the pull rod 24 and rotates the pull rod 24, the pull rod 24 can be fixed on the knob 19, so that the limit block 22 is slidably fixed in the movable groove 20.

[0027] Furthermore, the rear end of the limit block 22 and the openings of the multiple groups of limit grooves 23 are both arc-shaped, and the rear end of the limit block 22 is adapted to the inner walls of the multiple groups of limit grooves 23. This structure facilitates the limit block 22 to be quickly inserted into the limit groove 23 according to the shape of the rear end of the limit block 22 and the openings of the multiple groups of limit grooves 23.

[0028] Working principle: When training, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the insertion rod 14 is inserted into the through hole 13, and the multiple sets of second counterweights 12 in the fixed frame 10 are fixed on the connecting rod 11 according to the amount. Then the trainer holds the handle 7 and pulls the handle 7 to drive the sliding sleeve 5 to slide in the slide rail 4. When the handle 7 moves, the connecting rod 11 and the multiple sets of second counterweights 12 are pulled up and down in the fixed frame 10 by the pull rope 9, and the softball throwing exercise can be performed. When adjusting the height of the slide rail 4, as shown in FIG. Figure 4 and Figure 7 As shown, pulling the pull rod 24 drives the limit block 22 to slide out of the limit groove 23, and the limit block 22 slides into the movable groove 20, and the rotating pull rod 24 is fixed on the knob 19. Rotating the knob 19 drives the gear 17 to rotate, and the gear 17 rotates on the tooth groove 18, so that the support rod 16 slides up and down from the sleeve rod 15, so that the height position of the slide rail 4 installed at the upper end of the support rod 16 is adjusted, and then the pull rod 24 is twisted to release it from the knob 19, and the limit block 22 pops out from the movable groove 20 under the action of the restoring force of the spring 21 and is inserted into the limit groove 23, so that the knob 19 and the gear 17 can be fixed. The above is the entire working principle of the utility model.
