[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0031] Please refer to Figure 1 , the first technical solution adopted by the utility model is:

[0032] A motor output structure that is convenient for tool holder assembly, comprising a connecting mechanism and an output shaft connected to the output end of an external driving mechanism, the connecting mechanism being used to connect the driving shaft of the tool holder with the output shaft, a polygonal mounting hole being provided on the connecting mechanism, the cross-sectional shape of the output shaft being a polygon, the free end of the output shaft being inserted into the mounting hole, a spacing being provided between the output shaft and the mounting hole, and the output shaft being abutted against the inner wall of the mounting hole after being rotated at a certain angle.

[0033] From the above description, it can be seen that the beneficial effects of the utility model are:

[0034] The motor output structure designed in this scheme includes a connecting mechanism and an output shaft connected to the output end of an external driving mechanism. The connecting mechanism is used to connect the driving shaft of the tool holder with the output shaft. A polygonal mounting hole is provided on the connecting mechanism. The cross-sectional shape of the output shaft is polygonal. The free end of the output shaft is inserted into the mounting hole. A spacing is provided between the output shaft and the mounting hole. After the output shaft rotates a certain angle, it abuts against the inner wall of the mounting hole. By providing a transmission matching structure with a gap, the output shaft of the driving mechanism can have a movable space, which is convenient for the rapid assembly of the tool holder without the need for precise alignment, greatly reducing the difficulty of assembly.

[0035] Furthermore, the connection mechanism includes a mounting connection head, and the mounting hole is arranged on the mounting connection head.

[0036] Furthermore, the mounting hole is arranged on the mounting connector, a connecting piece is embedded in the mounting hole, the connecting piece has a polygonal through hole, the free end of the output shaft is inserted into the through hole, a spacing is arranged between the output shaft and the inner wall of the through hole and the output shaft abuts against the inner wall of the through hole after rotating a certain angle.

[0037] Furthermore, the through hole is in a quadrilateral shape.

[0038] Furthermore, a plurality of protrusions are provided on the outer wall of the connecting piece.

[0039] Furthermore, the connecting piece is made of metal.

[0040] From the above description, it can be seen that the material of the connecting piece is metal, which can increase the hardness of the connecting piece and provide stability for the output shaft of the driving mechanism to rotate at high speed.

[0041] Furthermore, the connecting mechanism also includes a driving connecting head, which is connected to the mounting connecting head, and the tool holder connecting head is connected to the driving shaft of the tool holder, a boss is provided on the outer wall of the tool holder connecting head, and a groove is provided on the driving connecting head for the tool holder connecting head to be inserted, and a rib matching the boss is provided on the inner wall of the groove.

[0042] From the above description, it can be seen that by setting the boss and the rib to cooperate with each other, a guiding effect is played, which can further improve the rapid assembly of the tool holder and the drive mechanism and further reduce the difficulty of assembly.

[0043] Furthermore, the connection mechanism further comprises a first output gear, and the mounting connector is arranged on an end surface of the first output gear;

[0044] There are two tool holders, and the motor output structure further includes a second output gear, which is meshed with the first output gear. The driving shafts of the two tool holders are respectively connected to the first output gear and the second output gear in a one-to-one correspondence.

[0045] From the above description, it can be seen that during assembly, the output shaft rotates a certain angle and then abuts against the inner wall of the mounting hole, so that the output shaft and the connecting mechanism form a whole. In this way, the driving mechanism starts to drive the output shaft to rotate, the rotation of the output shaft drives the first output gear to rotate, and the rotation of the first output gear drives the second output gear to rotate, thereby driving the two tool holders to rotate.

[0046] Furthermore, the cross-sectional shape of the output shaft is a quadrilateral.
