Specifically, the number of the mounting holes 143 on the adjusting base 14 may be matched with the number of the elastic assemblies 151 selected, and may be one or multiple, and those skilled in the art may set the number of the mounting holes 143 and the number of the elastic assemblies 151 according to actual needs, which is not limited by the embodiment of the present invention.
In some embodiments, by setting the depth of the mounting hole 143 and the thickness of the elastic member 151 in the second direction, the thickness of the mounted elastic member 151 is made larger than the depth of the mounting hole 143, that is, in the second direction in the transmission device, at a portion other than where the elastic member 151 is provided, a gap exists between the adjustment base 14 and the housing 10 to avoid direct contact between the adjustment base 14 and the housing 10 during transmission, so that noise generated by collision between the adjustment base 14 and the housing 10 can be reduced.
It can be understood that the depth of the mounting hole 143 and the thickness of the elastic component 151 in the second direction may be set according to actual requirements, and the embodiment of the present invention is not limited thereto.
Alternatively, referring to fig. 5 and 7, the mounting hole 143 includes: a first mounting hole 1431 and a second mounting hole 1432, wherein the second mounting hole 1432 is located on one side of the first mounting hole 1431 far away from the transmission bevel gear 13; the elastic member 151 includes: a spring 1511 and a resilient pad 1512; the spring 1511 is placed in the first mounting hole 1431; the resilient pads 1512 are positioned in the second mounting holes 1432.
In the embodiment of the present invention, the mounting hole 143 may include a first mounting hole 1431 and a second mounting hole 1432 disposed along the second direction, the elastic component 151 includes a spring 1511 and an elastic pad 1512, the spring 1511 and the elastic pad 1512 may be disposed in the first mounting hole 1431 and the second mounting hole 1432, respectively, and the elastic pad 1512 is located on a side of the spring 1511 away from the transmission bevel gear 13.

The elastic pad 1512 may also deform to a certain extent, which may play an auxiliary role in adjusting the relative position between the adjustment base 14 and the housing 10, and since the elastic pad 1512 abuts against the housing 10, noise generated by direct collision between the adjustment base 14 and the housing 10 during transmission may be reduced.
Optionally, in the second direction, the thickness of the resilient pads 1512 is greater than the depth of the second mounting holes 1432.
In the embodiment of the present invention, along the second direction, the thickness of the elastic spacer 1512 can be set to be greater than the depth of the second mounting hole 1432, one side of the elastic spacer 1512, which is away from the spring 1511, abuts against the housing 10, and in the operation process of the transmission, the elastic spacer 1512 can play a role in buffering between the adjusting base 14 and the housing 10, so as to avoid direct collision between the adjusting base 14 and the housing 10, thereby reducing noise generated by collision between the adjusting base 14 and the housing 10.
Specifically, the elastic member 151 may include: the spring 1511 is disposed in the first mounting hole 1431, the elastic pad 1512 is disposed in the second mounting hole 1432, and the elastic pad 1512 is disposed between the spring 1511 and the housing 10.
In the transmission process of the transmission device, the elastic assembly 151 is extruded by the adjusting base 14 and the housing 10 to deform, the thickness of the elastic gasket 1512 in the second direction is larger than the depth of the second mounting hole 1432, when the spring 1511 is compressed to the thickness consistent with the depth of the first mounting hole 1431, because the thickness of the elastic gasket 1512 is larger than the depth of the second mounting hole 1432, the direct contact between the adjusting base 14 and the housing 10 when the elastic assembly 151 deforms greatly can be avoided, and therefore noise generated by collision between the adjusting base 14 and the housing 10 can be reduced.
In some embodiments, the thickness of the elastic pad 1512 may be set to be greater than the depth of the second mounting hole 1432 after a predetermined amount of compression is generated, so that the elastic pad 1512 still can adjust the buffer function between the base 14 and the housing 10 after being deformed by compression during operation. Of course, the preset compression amount of the elastic pad 1512 and the thickness of the elastic pad 1512 can be set according to actual needs, and the embodiment of the present invention does not limit this.
In some embodiments, referring to fig. 5 to 7, a bearing 16 and a bolt 17 may be further disposed on the adjusting base 14, a bearing 16 hole 144 is disposed at an end of the adjusting base 14 facing the transmission bevel gear 13, the transmission bevel gear 13 is rotatably disposed in the bearing 16 hole 144 through the bearing 16, the bolt 17 passes through the transmission bevel gear 13 and is fixedly connected with the adjusting base 14, and the bolt 17 is in clearance fit with the transmission bevel gear 13.
