During row buffering, elastic telescopicing rod is compressed, and damping space is filled by bracket main body and two elastic telescopicing rods.Stretched using elasticity
Contracting bar and being flexibly connected between projection and support block（It is be hinged）, the vertical tremor suffered by bracket main body is effectively dispersed to
In horizontal direction or close in horizontal direction.Distance between two projections is less than the length under two elastic telescopicing rod static balance states
Sum is spent, is easy to two elastic telescopicing rods to make stretching motion when bracket main body is by vertical tremor.
Preferably, the damping also includes being arranged on the silicagel pad at the top of support block, effectively prevent due to vibrations
Amplitude it is excessive and cause the lower surface of bracket main body directly with support block at the top of be in contact, prevent the damage of hardware configuration, protect
The service life of whole engine bracker is demonstrate,proved.
Preferably, the damping also includes the spring being respectively sleeved on each elastic telescopicing rod, the both ends of spring
It is connected respectively with the both ends of elastic telescopicing rod so that the power being distributed on elastic telescopicing rod can be further distributed into elasticity and stretch
On contracting bar and spring, the damping effect for engine bracker is substantially increased, ensure that engine work to greatest extent
Stability.
Preferably, the damping is set at the corner of bracket main body, has both been beneficial to balance shock absorbing, has enable damping again
Ensure the damping effect of engine bracker to greatest extent.
Preferably, the engine installation structure includes the groove of location engine, and bracket main body is provided with fixation and started
The mounting hole of machine, it is easy to positioning, installation of the engine on engine bracker.
