[0029] In this embodiment, the lower end of the ball seat 1 is provided with a hinged seat 11, the hinged seat 11 is provided with a first hinged part 110 and a second hinged part 120, the upper end of the ball plate 2 is also provided with a hinged seat 11, which is hinged with the first hinged part 110 through a first hinged shaft 102, as shown in the figure, the hinged seat 11 is a parabolic structure, with a slot in the middle, arranged in an interval between the inside and outside, the swing rod 3 includes an upper swing rod 313 at the upper end, a lower swing rod 323 at the lower end and a hinged rod 33 in the middle, the ball control part 302 and the trigger part 301 are respectively located at the end of the upper swing rod 313 and the lower swing rod 323, preferably, the upper swing rod 313 and the lower swing rod 323 are both L-shaped, the rod bodies of the upper swing rod 313 and the lower swing rod 323 are connected head to tail to form a [swing rod 3, specifically, the hinged rod 33 is provided with a shaft hole 331, the shaft hole 331 is hinged with the second hinged part 120 through a second hinged shaft 103, one side of the ball seat 1 is also provided with a swing limiting piece 12, which can limit the downward stroke of the upper swing rod 313, in some optional embodiments, the position of the swing limiting piece 12 on the ball seat 1 can be adjusted, preferably, the adjustment mode is that a hanging plate is arranged on the side of the ball seat 1, a plurality of array holes are arranged along the swing arc line of the swing rod 3 as a track, the swing limiting piece 12 is arranged as a fixed screw 312, and the fixed screw 312 is fixed with different array holes, so that the lowest position of the ball control part 302 of the swing rod 3 can be changed, the ball clearance can be changed, and the purpose of controlling different sizes of balls can also be achieved.

[0030] In this embodiment, in order to realize that the swing rod 3 can automatically rebound quickly after losing the downward force of the ball plate 2, the weight ratio of the upper swing rod 313 and the lower swing rod 323 is adjusted, and another implementation scheme relying on elastic driving is also provided, specifically, a rebounding piece 13 is further included, the rebounding piece 13 is preferably a torsional spring, one end of the rebounding piece 13 is connected to the rod wall of the lower swing rod 323, and the other end acts on the lower side of the ball seat 1, when the lower swing rod 323 is pressed downward by the ball plate 2 and the downward force disappears, the lower swing rod 323 can quickly rebound upward by the rebounding force of the rebounding piece 13, so as to drive the upper swing rod 313 to quickly press downward, so as to reduce the ball clearance 101, so as to block the front of the second ball when it comes, and prevent it from passing, and the downward stroke is limited by the swing limiting piece 12, only after the previous ball rolls off along the ball plate 2 (in this process, the ball plate 2 rotates clockwise), the ball plate 2 will rotate counterclockwise, and finally the rear end of the ball plate 2 will press downward on the upper end surface of the lower swing rod 323, so as to again promote the upper end of the upper swing rod 313 to lift upward, so as to increase the ball clearance 101, so that the next ball can pass, and the process is repeated.

[0031] In this embodiment, both the ball-dropping seat 1 and the ball-dropping plate 2 have concave arc surfaces to form a rolling groove that facilitates the rolling of the ball.

For example, the required length ratio and front-to-back weight ratio of the ball drop board differ for lighter and heavier balls. Heavier balls experience greater gravity upon falling, so the front end of the ball drop board 2 can be slightly lighter because the gravity of the falling ball can cause the ball drop board 2 to rotate. However, when encountering lighter balls, a very sensitive adjustment of the front-to-back ratio is required. In this case, the ball drop board can be adjusted... The length can be adjusted by adding a counterweight module at the rear end of the ball plate. Specifically, a counterweight plate 4 is provided on one side of the ball plate 2, and a first mounting groove 201 is provided on one side of the ball seat 1. A second mounting groove 401 is provided on the counterweight plate 4 at the position corresponding to the first mounting groove 201. A hand-tightening screw 402 passes through both the first mounting groove 201 and the second mounting groove 401 to achieve adjustable installation of the counterweight plate 4 and the ball plate 2. Both the first mounting groove 201 and the second mounting groove 401 are long grooves, which can realize the adjustment of the counterweight plate 4 at the rear end of the ball plate 2. Of course, there are many ways to adjust the rotation sensitivity of the ball plate 2, which will not be described in detail here.

[0033] In this embodiment, the ball-dropping board 2 includes a main board body 21 and an extension board body 22. A connector 211 is provided on one side of the main board body 21, and a insertion groove 221 is provided on the side of the extension board body 22 corresponding to the connector 211. The connector 211 and the insertion groove 221 are mutually inserted and engaged. In this embodiment, a buckle 211a is provided on one side of the connector 211, and an insertion hole 221a is provided on the inner side of the insertion groove 221. The buckle 211a and the insertion hole 221a are mutually inserted and locked together. The buckle 211a has a beveled surface.

[0034] As a subsequent embodiment of the improvement, in order to be able to adjust the ball clearance 101 of the upper swing rod 313 when opening without the help of other adjusting mechanisms, here, a hinged rod 310 is further provided at the upper end of the hinged rod 33, the hinged rod 310 is provided with a hinged hole (or a hinged cavity, not shown here, the upper end is open for the hinged rod 310 to insert), the hinged hole is provided with a fixed hole 315 on the outside, and the fixed screw 312 is inserted into the hinged hole from one side of the fixed hole 315 to lock the upper swing rod 313, the lower end of the upper swing rod 313 is inserted and matched with the hinged hole while being fixed by the fixed screw 312, in order to quickly find the corresponding insertion depth for balls of different sizes, here, the lower end of the upper swing rod 313 is provided with an adjustment area 313, and a plurality of gear marks 314 corresponding to balls of different diameters are arranged in the adjustment area 313, different gears correspond to balls of different diameters, such as tennis balls corresponding to the insertion depth mark A, and pétanque balls corresponding to the insertion depth mark B, next time when training, for the balls used corresponding to different ball games, only the corresponding mark is found to be inserted, and then the fixed screw 312 is inserted and fixed.

[0035] The utility model discloses still a kind of plummet device 1000, including support mechanism 200, ball storage mechanism 300 and the plummet mechanism 100 described above, the upper portion of the support mechanism 200 is installed ball storage mechanism 300, the plummet mechanism 100 is arranged at the output end of ball storage mechanism 300, ball storage mechanism 300 is preferably spiral raceway type, and pipe body type ball storage device can also be selected.

[0036] Here, it is necessary to describe the plummet principle of the utility model for the following, for understanding:

[0037] When needing to start training, fill the ball in ball storage mechanism, then when ready to swing, press the rear end of plummet plate (such as the left end shown in Fig. Figure 1 At this time, the left end of plummet plate is pressed downward to drive the lower swing rod to swing downward, so as to drive the upper swing rod at upper end to swing upward, that is, the upper swing rod and the lower swing rod swing counterclockwise, the ball clearance between the upper swing rod and the plummet seat increases after the upper swing rod swings upward, the first ball slides downward when reaching the target ball clearance, and then enters the front end of plummet plate ( Figure 1Because the ball seat is located at the upper end of the ball drop plate, when the ball rolls down behind the ball drop plate, the original balance of the ball drop plate is broken, that is, the weight of the front end of the ball drop plate plus the weight of the rolling ball is greater than the weight of the rear end, thus, similar to a seesaw, the front end of the ball drop plate swings downward, and the ball also rolls forward quickly, and the faster the ball rolls, the farther the ball is from the first hinge, so the faster the ball drop plate swings, and at the moment when the ball drop plate swings clockwise, the rear end of the ball drop plate is separated from the downward pressure on the swing rod, at this time, the swing rod swings upward quickly under the action of the torsion spring, the upward swing rod quickly presses downward, thereby quickly reducing the ball passing gap, so the second ball is blocked and cannot pass through, after the first ball falls, the user swings the racket to hit the ball, and then the ball drop plate returns to the original gravity ratio (the original gravity ratio is that the weight of the rear end of the ball drop plate is slightly greater than the weight of the front end, and this kind of balance can be achieved by adjusting the counterweight plate or adjusting the extension plate body at the front end), thus the ball drop plate returns to the downward pressing process, and the second ball is hit repeatedly, and so on.

[0038] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application all belong to the scope of protection of the present application.
