[0052] Furthermore, wheels 42 are rotatably provided at both ends of the bottom surface of the longitudinal beam 4 of the base 1, and support legs 43 are respectively provided on the outer sides of the two wheels 42 on the bottom surface of the longitudinal beam 4. The support legs 43 include a screw 44 and a support 45 fixedly connected to the lower end of the screw 44. The screw 44 is threadedly connected to the longitudinal beam 4.

[0053] The working principle of the above technical solution is as follows: wheels 42 are rotatably provided at both ends of the bottom of the longitudinal beam 4 of the base 1 of the telescopic billiard ball placing device, so as to facilitate pushing the telescopic billiard ball placing device under the billiard table body 100. Support legs 43 are provided on the outer side of the middle position between the two wheels. After the telescopic billiard ball placing device is pushed into place, the screw threadedly connected to the bottom surface of the longitudinal beam is rotated to move the support downward, thereby raising the base 1, and the wheels 42 are separated from contact with the ground. The support legs make the telescopic billiard ball placing device be located at the set position below the billiard table body 100.

[0054] A base motor 9 is fixedly installed on the inner side surface of the cross beam 5 of the support 1. The base motor 9 is arranged in the middle of the two longitudinal beams 4. The base motor 9 is a dual-axis motor. The two power output shafts of the base motor 9 are respectively fixed with first sprockets 10. The first sprocket 10 is rotatably set on the inner walls of the two longitudinal beams. The second sprocket 11 is relatively set on the inner wall of the two longitudinal beams 4 away from the cross beam. The second sprocket 11 is transmission connected to the first sprocket 10 through a first chain, and the chain is fixedly connected to the slider 7.

[0055] Figure 1This is the initial state of the lifting assembly and the telescopic arm assembly. In the initial state, the lifting assembly is in a lowered state and the telescopic arm assembly is in a retracted state. After the ball is placed in the swing ball mold 101 fixed on the telescopic arm assembly, the base motor 9 is started. The base motor 9 drives the slider 7 to move through the first sprocket 10 and the chain. The slider 7 drives the sliding beam 8 to move toward the end of the crossbeam 5 away from the base 1. The sliding beam 8 drives the lifting assembly set on the sliding beam 8 and the telescopic arm assembly connected to the lifting assembly to move to the range where the table top of the billiard table body is located. When the part of the telescopic arm assembly closest to the crossbeam 5 moves to the range where the billiard table body is located, the base motor 9 stops, and the lifting stage and the telescopic arm assembly also stop. At this time, the drive motor 17 of the lifting assembly 2 is started, and the drive motor 17 drives the third sprocket 18 and the second chain 20 to drive the lifting connecting plate 21 to rise. The lifting connecting plate 21 drives the lifting plate 16 to rise, thereby driving the telescopic arm assembly set on the lifting plate to rise. The lowest point of the telescopic arm assembly and the swing ball mold is higher than the height of the top surface of the billiard table body 100. After that, the driving motor stops and the lifting assembly also stops. At this time, the telescopic motor 30 starts, drives the first pulley 28 to rotate through the transmission mechanism, and drives the telescopic arm to move in the direction away from the lifting assembly through the first belt 31. When the ball-swinging mold 101 reaches the position for swinging the ball on the table surface of the billiard table body 100, the telescopic motor 30 stops. At this time, the driving motor 17 rotates in the reverse direction to make the lifting assembly drive the telescopic arm assembly to descend, so that the lower part of the ball-swinging mold contacts the table surface of the billiard table body 100. The driving motor 17 stops. After the ball-swinging mold places the ball on the table surface of the billiard table body 100, the driving motor rotates forward to make the telescopic arm assembly and the ball-swinging mold rise to the position where the last stop is reached. Then the driving motor stops. Then the telescopic motor 30 rotates in the reverse direction to retract the telescopic arm assembly. Then the driving motor rotates in the reverse direction to make the lifting assembly descend. After the assembly has fallen into place, the base motor starts and rotates in the reverse direction, drives the slider 7 to move in the direction close to the crossbeam 5 through the first sprocket and the first chain, so that the lifting assembly and the telescopic arm assembly return to their initial positions, completing one ball-swinging operation.

[0056] The C-shaped opening direction of the outer slide rail 24 and the middle slide rail 25 of the slide rail unit is toward the middle of the two telescopic arm brackets 22, and the opening direction of the inner slide rail 26 is opposite to the opening direction of the outer slide rail 24. The telescopic arm 27 is fixed to the back side of the C-shape of the inner slide rail. Since the two sets of slide rail units are arranged between the two telescopic arm brackets 22 and the swing ball mold 101 is fixed between the two telescopic arms 27, the C-shaped outer slide rail, middle slide rail and inner slide rail are nested with each other and will not fall off. In order to prevent the middle slide rail and the inner slide rail from falling off in the length direction, a blocking structure in the length direction can be set between the slide rails. Since there are many anti-falling structures in the length direction of multi-section slide rails, they will not be described here.

[0057] The base plate 12 can be set to a U shape, so that the height between the two longitudinal beams 4 can be better utilized, which can be used to increase the lifting height of the lifting assembly. A motor connecting plate 121 is fixedly set on the front side of the base plate 12, and the drive motor 17 is fixedly set on the motor connecting plate 121. The power output shaft of the drive motor 17 passes through the motor connecting plate 121 and enters the U-shaped base plate 12 and is fixedly connected to the third sprocket 18.

[0058] An isolation plate 47 is fixedly provided on the front side of the lifting assembly, and an isolation cover 46 is fixedly provided on the outside of the lifting assembly, which can both beautify and protect. A similar isolation structure is also provided on the telescopic arm assembly, which will not be described in detail here.
