Wherein, accommodation space 201 is adapted to connection end 105 setting, connection end 105 inserts in accommodation space 201, and the connecting piece wears to establish in accommodation space 201. That is, the cross section of the accommodating space 201 is identical to that of the connecting end 105, and the dimensions of the two are basically identical, so that the connecting end 105 can be smoothly inserted into the accommodating space 201. By inserting the connector into the accommodation space 201, the connector can be prevented from being contaminated by external impurities, and the later disassembly and maintenance are facilitated.

In addition, as a preferred embodiment, the limiting groove 2012 is adapted to the limiting protrusion 602, and the cross section and the size of the limiting protrusion 602 are consistent, so that each side surface of the limiting protrusion 602 can be tightly matched with the suspension bracket 2, thereby improving the limiting capability and the bearing capability, reducing the load born by the connecting piece, and being beneficial to preventing the loosening of the connecting piece. In this embodiment, as a preferred embodiment, the connector is a bolt 3, for this purpose, as shown in fig. 5 and 6, a through hole 2011 through which the connector passes is provided on a side wall of one side of the accommodating space 201, and a relief portion 2013 communicating with the accommodating space 201 is provided on a side wall of the other side of the accommodating space 201.

The inner diameter of the via 2011 is slightly larger than that of the connection hole 601, so as to absorb assembly tolerance and ensure that a bearing surface N and a mating surface M described below are tightly matched. While the avoidance portion 2013 is used for avoiding the shaft portion of the bolt 3, and specifically is configured as an avoidance groove penetrating through the notch of the accommodating space 201, the avoidance portion 2013 may be configured as an avoidance hole, in addition to the avoidance groove.

In order to improve the connection tightness between the bolt 3 and the connection end 105, the inner and outer surfaces of the side wall of the suspension bracket 2 provided with the via 2011 are both plane surfaces. By such a design, as shown in fig. 3, when the bolt 3 is coupled in the coupling hole 601, the coupling end 105 and the bolt 3 can be firmly clamped to the inner and outer sides of the suspension bracket 2, respectively. Thereby, the load in the X direction borne by the bolt 3 can be shared by the side walls of the suspension bracket 2 clamped, so that the connection reliability between the bolt 3 and the connection end 105 can be improved. Here, the connector may be a pin, in addition to the bolt 3.

In addition, the cross section of the main body is the same as that of the groove 1052, and the size is basically consistent, so that the main body can be smoothly inserted into the groove 1052. In this embodiment, to facilitate the insertion of the limiting protrusion 602 into the limiting groove 2012, the width of the limiting protrusion 602 is gradually reduced along the direction away from the inner core 101, so that the limiting protrusion 602 is substantially V-shaped, and the top of the limiting protrusion 602 is configured to be flat to avoid stress concentration.

Of course, the marking portion may be formed in other shapes such as a triangle instead of the arrow, and the marking portion may be formed on the connecting end 105 or the core 101 instead of the stopper projection 602.

Further, as a preferred embodiment, as shown in fig. 14, the elastic body of the present example is a rubber pad 7 provided in the groove 1052. And the rubber pad 7 is fitted in the groove 1052, i.e. the rubber pad 7 has the same cross section as the groove 1052 and substantially the same dimensions as the groove 1052. It should be noted that, instead of using the rubber pad 7, it is also possible to use a spring that abuts between the connection block 6 and the connection end 105.
