The installation box 1 is also provided with a controller, and the controller is electrically connected to the first electric push rod 21, the electric slide 5 and the multi-angle adjustment mechanism 7. In this way, different commands can be implemented by first writing a controller program, and the battery assembly 11 is used to power them respectively, and then multiple table tennis balls are placed in the storage tube 4, and then the table tennis balls will pass through the passing tube 3 and enter the serving tube 2, and then through the operation of the electric slide 5, the serving tube 2 can be driven to move horizontally, and then through the multi-angle adjustment structure, the serving tube 2 can also rotate at multiple angles, so that after the table tennis ball is pushed by the first electric push rod 21 to be launched, the table tennis ball can be launched at different angles, and the electric slide 5 can drive the serving barrel 2 to move in a direction parallel to the table tennis seat, so that the serving barrel 2 can be raised to different horizontal positions when launching the table tennis ball, which can increase the difficulty of the practitioner when receiving the table tennis ball, thereby improving the practitioner's level, and the multi-angle adjustment mechanism 7 can further increase the different angles of the serving barrel 2 when launching the table tennis ball, which can further increase the difficulty of the practitioner when receiving the table tennis ball, thereby further improving the practitioner's level.

[0027] Reference Figure 2 , Figure 5 and Figure 6 The multi-angle adjustment mechanism 7 includes a fixed plate 71, a fixed seat 712 and a mounting seat 73; the fixed plate 71 is arranged above the electric slide 5, and two limit plates 711 are symmetrically arranged on the fixed plate 71; the fixed seat 712 is arranged on the limit plate 711, and a rotatable sleeve 72 is arranged on the fixed seat 712, and the sleeve 72 can penetrate the fixed seat 712; the mounting seat 73 is arranged on the top of the sleeve 72, and a rotatable rotating shaft 74 is arranged on the mounting seat 73, and the rotating shaft 74 is connected to the serving barrel 2 through a fixed block 741.

[0028] By driving the sleeve 72 to rotate on the fixed seat 712, the mounting seat 73 is driven to rotate in a direction parallel to the table tennis seat, and the serving barrel 2 is also driven to rotate in a direction parallel to the table tennis seat, so as to change the angle of the serving barrel 2 when launching the table tennis ball, thereby further increasing the difficulty of the practitioner in catching the table tennis ball, and further improving the practitioner's level.

[0029] Reference Figure 5 and Figure 6As shown, a driving assembly 75 is provided on the fixed plate 71, and the driving assembly 75 includes a first motor 751, a first worm 753 and a first worm wheel 752; the first motor 751 is provided on the fixed plate 71; the first worm 753 is provided on the limiting plate 711 through a bearing seat, and the first worm 753 is connected to the output end of the first motor 751; the first worm wheel 752 is provided at the bottom of the sleeve 72, and the first worm wheel 752 is meshingly connected with the first worm 753.

[0030] By starting the first motor 751, when the output end of the first motor 751 rotates, the first worm 753 is synchronously driven to rotate. Through the setting of the first worm gear 752, the sleeve 72 is synchronously driven to rotate, and then the serving barrel 2 is directly rotated in a direction parallel to the table tennis seat, which can reduce manual operation and improve the convenience of operation.

[0031] Reference Figure 5 and Figure 6 As shown, a rotating assembly 76 is provided on the fixed plate 71, and the rotating assembly 76 includes a connecting shaft 761, a first bevel gear 762 and a second bevel gear 763; the connecting shaft 761 is coaxially arranged on the sleeve 72, and the connecting shaft 761 can pass through the sleeve 72; the first bevel gear 762 is arranged on the top of the connecting shaft 761; the second bevel gear 763 is arranged on the rotating shaft 74, and the second bevel gear 763 is meshed and connected with the first bevel gear 762.

[0032] By driving the connecting shaft 761 to rotate, the first bevel gear 762 will be synchronously driven to rotate in a direction parallel to the table tennis seat, and then the second bevel gear 763 will be driven to rotate in a direction perpendicular to the table tennis seat, thereby driving the serving barrel 2 to rotate in a direction perpendicular to the table tennis seat, which can further increase the rotation angle of the serving barrel 2, thereby further increasing the angle of the serving barrel 2 when launching the table tennis ball, which can further increase the difficulty of the practitioner in catching the table tennis ball, and further improve the practitioner's level.

[0033] Reference Figure 5 and Figure 6As shown, a driving part 77 is provided on the fixed plate 71, and the driving part 77 includes a second motor 771, a second worm 773 and a second worm wheel 772; the second motor 771 is arranged on the side of the fixed plate 71 away from the first motor 751; the second worm 773 is arranged on the limiting plate 711 through a bearing seat, and the second worm 773 is connected to the output end of the second motor 771; the second worm wheel 772 is arranged below the first worm wheel 752, the second worm wheel 772 is connected to the bottom of the connecting shaft 761, and the second worm wheel 772 is meshingly connected with the second worm 773.

[0034] By driving the second motor 771, when the output end of the second motor 771 rotates, the second worm 773 will be driven to rotate synchronously. Through the setting of the second worm gear 772, the connecting shaft 761 will be driven to rotate synchronously, and then the serving barrel 2 will be directly rotated in a direction perpendicular to the table tennis seat, which can further reduce manual operation and further improve the convenience of operation.

[0035] Reference Figure 2 and Figure 4 As shown, the clamping assembly 6 includes a first clamping plate 61, a second clamping plate 63 and a fixing bolt 65; at least one of the first clamping plates 61 is arranged on the installation box 1, and the first clamping plate 61 is rotatably connected to the installation box 1, and the installation box 1 is provided with a first placement groove 62 for the first clamping plate 61 to be placed; the number of the second clamping plates 63 is the same as that of the first clamping plates 61, the second clamping plates 63 can be rotatably arranged on the installation box 1, and the installation box 1 is provided with a second placement groove 64 for the second clamping plate 63 to be placed; the fixing bolt 65 is provided with one on the first clamping plate 61, and the second clamping plate 63 is provided with an abutment block 66 that cooperates with the fixing bolt 65.

[0036] When the installation box 1 needs to be fixed on the table tennis seat, first rotate the first clamping plate 61 and the second clamping plate 63 to a certain angle respectively, then move the first clamping plate 61 and the second clamping plate 63 to the top and bottom of the table tennis seat respectively, and then fix the first clamping plate 61 and the second clamping plate 63 to the table tennis seat through the cooperation of the fixing bolt 65 and the abutment block 66, so as to fix the installation box 1 on the table tennis seat. When not in use, loosen the fixing bolt 65 first, and then rotate the first clamping plate 61 and the second clamping plate 63 to the first placement groove 62 and the second placement groove 64 on the installation box 1, so as to reduce the volume and facilitate carrying or transportation.

[0037] Reference Figure 6 As shown, a lifting assembly 51 is provided on the electric slide 5, and the lifting assembly 51 includes a second electric push rod 511, and the second electric push rod 511 is vertically arranged on the electric slide 5, and the working end of the second electric push rod 511 is connected to the fixed plate 71.

[0038] When the serving barrel 2 is needed for serving practice, the second electric push rod 511 is first driven to operate so that the serving barrel 2 is moved out of the installation box 1. Then, when the serving barrel 2 is no longer needed for serving practice, the serving barrel 2 is driven to be stored in the installation box 1 through the operation of the second electric push rod 511. This can further reduce the volume and thus further improve the convenience during carrying or transportation.

[0039] Reference Figure 2 As shown, the installation box 1 is also provided with a rotatable handle 12 .
