The elastic element 132 has good buffering capacity by using the silica gel element and the rubber element with certain strength and elasticity, and the elastic element 132 buffers the vibration of the main body 11 when being sleeved on the main body 11, so that the steering error of the main body 11 is reduced. Of course, the elastic member 132 can also be made of other materials with better elasticity and strength, and will not be described herein.

In some embodiments, the elastic member 132 is in a sleeve shape, the elastic member 132 has an inner hole 1321 adapted to the frame connecting portion 112, the elastic member 132 further has a slit 1322 penetrating through a side wall of the elastic member 132 in both axial and radial directions, so that the elastic member 132 fits the inner hole 1321 on the frame connecting portion 112 through the slit 1322 to limit and fix the elastic member 132 by the frame connecting portion 112, the elastic member 132 having the slit 1322 is simpler to mount on the main body 11, generally, the elastic member 132 has a slit 1322 with a relatively smaller width, so that the elastic member 132 can be mounted on the main body 11 relatively quickly, preferably, the slit 1322 provided on the elastic member 132 has a width of 1-2mm, which not only can make the slit 1322 have less influence on elasticity and hardness of the elastic member 132, but also make the main body 11 relatively faster to mount the elastic member 132, the working efficiency is higher.

As shown in fig. 4, the supporting seat 131 has an opening 1311, and the slit 1322 of the elastic member 132 is disposed toward the opening 1311.

In the embodiment shown in fig. 4 and 5, the supporting seat 131 includes a hoop body 1312 and mounting lugs 1313 connected to two ends of the hoop body 1312, the two mounting lugs 1313 are symmetrically disposed and extend away from each other, the elastic member 132 has a first side wall 1323, a second side wall 1324 and a third side wall 1325 connected in sequence, the second side wall 1324 is connected between the first side wall 1323 and the third side wall 1325, a gap 1322 is formed between the first side wall 1323 and the third side wall 1325, and the second side wall 1324 is matched with the inner wall of the hoop body 1312 in the hoop body 1312.

The first side wall 1323 and the third side wall 1325 are arranged oppositely, the cross section of the second side wall 1324 is semicircular, the first side wall 1323 and the third side wall 1325 are relatively limited by the inner wall of the hoop body 1312, the second side wall 1324 is matched and limited with the semicircular inner wall in the hoop body 1312, the hoop body 1312 can be limited by the mounting lugs 1313 connected to the two ends of the hoop body 1312, the supporting seat 131 is clamped, the limiting effect of the elastic piece 132 is better, in addition, the mounting lugs are provided with mounting holes, and the main body machine 11 can be fixed on a frame of a vehicle through fixing pieces such as fastening bolts 130.

Thus, the elastic member 132 is defined by the mounting ears 1313, so that the elastic member 132 is in close contact with the main body 11, and the vibration damping effect of the elastic member 132 on the main body 11 is better.
