After repeated splicing, the splicing parts will become loose after splicing due to reduced wear, which directly affects the splicing effect. This requires replacing one or some parts, resulting in an increase in the cost of use. Summary of the invention

[0038] The main board and the first reduction box 2 and the second reduction box 3 arranged on both sides of the main board; the outward driving force is generated by the reduction mechanism arranged in the first reduction box 2 and the second reduction box 3 cooperating with the driving mechanism arranged on the main board; of course, in the present invention, the circuit board is also arranged on the main board, and the start and stop of the driving mechanism can be controlled by connecting the circuit board with the driving mechanism; of course, a signal receiving device can also be arranged as needed, and the present invention does not further limit this; and in the present invention, the circuit board can be fixed on the main board by snapping; considering reducing the overall size and the strength of the circuit board installation, therefore, in the present invention, it is preferred to provide an installation groove 71, which is arranged on the board body and cooperates with the fourth connecting hole 72 on the board body to fix the circuit board; that is, the bolts are passed through the fourth connecting hole 72 and the circuit board in sequence and then fixed to the board body, thereby achieving the fixation of the board body;

[0039] In addition, in the present invention, the main board includes a transverse plate 11 and a longitudinal plate 12, and the transverse plate 11 and the longitudinal plate 12 are fixed vertically; and the driving mechanism is fixed on the transverse plate 11, specifically, a motor slot 91 is provided on the transverse plate 11, and the driving mechanism can be directly placed in the motor slot 91, and the driving mechanism is clamped with the driving mechanism through a clamping wing 92 provided on the transverse plate 11, thereby achieving the fixing of the driving mechanism; the circuit board is arranged adjacent to the longitudinal plate 12, and the fourth connecting hole 72 is provided on the longitudinal plate 12, and when the circuit board is inserted into the mounting slot 71, the bolts are passed through the fourth connecting hole 72 and the circuit board in sequence and then fixed to the board body, thereby achieving the fixing of the circuit board, and in the present invention, preferably there are two fourth connecting holes 72, which are relatively arranged on both sides of the longitudinal plate 12;

[0040] Furthermore, in order to facilitate the confirmation of direction and improve the efficiency of assembly during use, the present invention preferably has a plurality of marks 8, which are respectively arranged on the first reduction box 2 and the second reduction box 3; Figure 1 and Figure 2 As shown, a mark "S" is provided on the first reduction box 2, and a mark "N" is provided on the second reduction box 3, and the left and right directions are determined by "S" and "N"; in addition, "W" and "V" are provided on the first reduction box 2 and the second reduction box 3, respectively, and the first reduction box 2 and the second reduction box 3 are arranged relative to each other, so that the front and rear directions can be determined by "W" and "V", and then the required direction can be obtained directly by the mark 8 during the assembly process, thereby improving the efficiency of assembly; of course, other marks 8 can be added or replaced with other marks 8 as needed, which depends on the actual situation, and the present invention will not be further limited to this;

[0041] A first connection area 41 and a second connection area 42 are formed between the main board and the first reduction gearbox 2 and the second reduction gearbox 3, and the first connection area 41 and the second connection area 42 are arranged opposite to each other; that is, the first connection area 41 and the second connection area 42 are arranged opposite to each other on both sides of the main board, so that different extensions can be installed during the use stage; first connection structures 51 are respectively arranged at both ends of the first connection area 41, and second connection structures 52 are respectively arranged at both ends of the second connection area 42; the extensions are installed through the first connection structure 51 and the second connection structure 52; in addition, it should be noted that the first connection structure 51 is respectively arranged at one end of the first reduction gearbox 2 and one end of the second reduction gearbox 3; the second connection structure 52 is respectively arranged at the other end of the first reduction gearbox 2 and the other end of the second reduction gearbox 3; this ensures a symmetrical structure and improves the stability of the installation; wherein,

[0042] The first connection structure 51 includes a boss 511 and a first limiting plate 512, wherein the boss 511 is arranged on the first reduction box 2; the first limiting plate 512 is arranged on the boss 511, and an angle α is formed between the first limiting plate 512 and the boss 511; that is, the first limiting plate 512 and the boss 511 form a stepped state, thereby increasing the contact area during the installation of the extension piece and improving the stability of the extension piece after installation; in addition, in the present invention, the angle α between the first limiting plate 512 and the boss 511 is an angle greater than 90°, and is preferably 91° in the present invention, so that the first limiting plate 5 12 is in a beveled state on one side of the first connection area 41; in addition, a side of the boss 511 adjacent to the first connection area 41 is also in an inclined state, and this side is parallel to the inclined surface of the first limit plate 512; in this way, the four sides of the first connection area 41 both contain two inclined surfaces, and when the extension piece enters, a transition experience from loose to tight will be generated; and in the subsequent production process of the extension piece, the dimensional error caused by the material production process does not need to be considered; in addition, in the process of molding, the existence of the inclined surface can facilitate demoulding after production is completed, thereby improving the efficiency of the production process;

[0043] Of course, in order to ensure the accuracy of installation during the installation of the extension piece, in the present invention, a first guide rail 513 is preferably provided, and the first guide rail 513 is provided on the first limiting plate 512; in this way, during the installation process, the extension piece can be limited by the first guide rail 513 (a groove matching the first guide rail 513 is provided on the extension piece, and the extension piece is limited by the cooperation between the first guide rail 513 and the groove); in addition, in the present invention, the cross-section of the first guide rail 513 is an isosceles triangle, and the three angles are all 45°, so that the groove on the extension piece needs to meet the 45° structure. Therefore, if the groove angle of the extension piece is less than 45°, the firmness of the extension piece and the first guide rail 513 after being fitted together will be reduced; and when the groove angle of the extension piece is greater than 45°, in the subsequent molding process, the temperature of the hot melt molding using the 3D printer is too high, resulting in the dispersion of forces during the stacking of the extension piece, resulting in molding failure;

[0044] like Figure 1 , 3 As shown in FIG. 4 , the present invention further provides a limiting protrusion 514, which is provided on the boss 511; and the extension piece is provided with a structure adapted to the limiting protrusion 514, so that the contact area between the extension piece and the first connecting space 516 can be further increased, thereby improving the fixing strength of the extension piece; in addition, the limiting protrusion 514 is a circular chamfered structure, so that it can better contact with the extension piece and improve the fixing effect; as shown in FIG. Figure 4As shown, a connection space 516 is further provided at one end of the boss 511, and the connection space 516 is formed by combining the boss 511 and the first limiting plate 512; and a protruding structure adapted to the connection space 516 is provided on the extension piece, so that, on the one hand, it is possible to judge whether the extension piece is installed correctly through the connection space 516, and on the other hand, the contact area between the extension piece and the first connection structure 51 can be increased through the connection space 516, thereby improving the strength of the extension piece after installation;

[0045] In addition, in the present invention, the extension piece can be fixed to the first connection area 41 by a combination of the extension piece. In order to improve the efficiency of disassembly and assembly, in the present invention, preferably, a plurality of first connection holes 515 are provided on the first limit plate 512; bolts are passed through the first connection holes 515 to fix the extension piece, which can reduce the wear of the extension piece and the first connection area 41, and does not affect the fixing strength between the extension piece and the first connection area 41;

[0046] In the present invention, the first connection structures 51 at both ends of the first connection area 41 have the same structure and are only arranged relative to each other. They are used in conjunction with each other during the installation of the extension piece. To save space, the present invention will not further describe the first connection structure 51 at the other end.

[0047] like Figure 2 As shown, the second connection structure 52 includes a second limit plate 521, which is arranged on the first reduction box 2, and there is an angle β between the second limit plate 521 and the plate body; in the present invention, the second connection structures 52 at both ends of the second connection area 42 are used simultaneously, and when the extension piece is placed in the second connection area 42, the two second connection structures 52 pass through the restriction of the near-line second extension piece; the extension piece is installed in the second connection area 42; in addition, there is an angle β between the second limit plate 521 and the longitudinal plate 12, and in the present invention, the preferred angle β is greater than 90°, preferably 91°; in this way, the second limit plate 521 is in a beveled state on one side of the second connection area 42; in this way, when the extension piece enters, a transition experience from loose to tight will be generated; and in the subsequent production process of the extension piece, the dimensional error caused by the material production process can be ignored;

[0048] like Figure 2As shown, a second guide rail 523 is also provided on the second limiting plate 521, so that during the installation process, the extension piece can be limited by the second guide rail; in addition, in the present invention, the cross section of the second guide rail is a fixed triangle, and the three angles are all 45°, so that the groove on the extension piece needs to meet the 45° structure. Therefore, if the angle of the groove of the extension piece is less than 45°, the firmness of the extension piece and the second guide rail 523 after being attached will be reduced; and when the angle of the groove of the extension piece is greater than 45°, in the subsequent molding process, the temperature of the hot melt molding using the 3D printer is too high, resulting in the dispersion of force during the stacking of the extension piece, resulting in molding failure;

[0049] In addition, in the present invention, the extension piece can be fixed in the second connection area 42 by snapping or using other extension piece cooperation. Of course, other methods can also be used, and the present invention will not cite examples one by one; but in the present invention, it is preferred that a plurality of second connection holes 522 are provided on the second limit plate 521; bolts are passed through the second connection holes 522 and fixed to the extension piece, which can reduce the wear of the extension piece and the second connection area 42, and does not affect the fixing strength between the extension piece and the second connection area 42;

[0050] It should be noted that the second connection structures 52 at both ends of the second connection area 42 are of the same structure and are only arranged relative to each other; in order to save space, the present invention will not further explain this;

[0051] Different extensions can be installed according to changes in actual use needs; therefore, in the present invention, it is preferred to provide a plurality of third connecting holes 6, which are respectively arranged on the surfaces of the first reduction box 2 and the second reduction box 3 parallel to the plate body; of course, according to changes in use, the third connecting holes 6 can also be preset at other positions, so that different extensions can be installed as needed through the provision of a plurality of third connecting holes 6, thereby further improving the flexibility of the use of the extensions.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
