, comprise for the base of fixed bumper with for the block of the power of withstanding shocks; The middle part of described base is with mandrel, described base has between a side of mandrel and block and is provided with elastic element, the periphery of elastic element is provided with elastic element supporting sleeve, joint at described elastic element supporting sleeve and block is provided with the end cap for spacing described block, and described end cap and elastic element supporting sleeve are bolted on base.
Wherein, the free height of described elastic element is greater than the height of mandrel.
Wherein, described elastic element is fixedly connected with block.Elastic element and block form a stressed live body, the stability in the time of can improving buffer buffers.
Wherein, described elastic element is butterfly spring group, and the free height of described butterfly spring group is greater than the height of described mandrel.
Wherein, described elastic element comprises butterfly spring group and is fixed on the backing plate at butterfly spring group two ends, the free height sum of described butterfly spring group and two backing plates is greater than the height of described mandrel, and the backing plate of the contiguous block of described butterfly spring group one end is fixed on block.
Wherein, described block is T-shaped.
Wherein, on described base, be equipped with a plurality of bolts hole for fixed bumper base.Thereby can buffer base be fixed on apparatus body by bolt, and then buffer is fixed on apparatus body.
Wherein, described end cap ringwise.
Wherein, the transverse section of described end cap is L-type.
Compared with prior art, the utility model has the advantage of:
(1) the utility model comprises with the base of mandrel with for the block of the power of withstanding shocks, at base, have between a side of mandrel and block and be provided with elastic element, in the periphery of elastic element, be provided with elastic element supporting sleeve, in the joint of elastic element supporting sleeve and block, be provided with the end cap for spacing described block, and end cap and elastic element supporting sleeve are bolted on base, simple in structure, not only easy to use, and be convenient to produce;
(2) the utility model is fixedly connected with elastic element with block, makes to form a complete stressed live body, thereby makes buffering course more stable;
(3) elastic element of the present utility model adopts butterfly spring group, the use of butterfly spring group, not only increased the cushion effect that buffer can bear, also solved the contradiction that buffer shaft is large to volume and installing space is little, also avoided the generation of " resilience is jolted " phenomenon after buffering, make buffer no longer along the significantly resilience of axle of spring direction, buffering course is very stable, and saved the buffer time of buffer, avoided the damage of apparatus body and the generation of security incident simultaneously, practical;
(4) elasticity butterfly spring group of the present utility model is fixed on block by backing plate, makes impact force be acted on equably butterfly spring group, thereby increases the stability of buffer buffers process, and then increases the working life of buffer.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.

Embodiment
For ease of explanation, below in conjunction with accompanying drawing, the utility model is described in further detail.
Mode of execution 1:
As shown in Figure 1, a kind of buffer of the present utility model, comprises for the base 2 of fixed bumper with for the block 6 of the power of withstanding shocks; The middle part of described base 2 is with mandrel 10, described base 2 has between a side of mandrel 10 and block 6 and is provided with elastic element, the periphery of elastic element is provided with elastic element supporting sleeve 4, in described elastic element supporting sleeve 4 and the joint of block 6, be provided with the end cap 7 for spacing described block 6, described end cap 7 and elastic element supporting sleeve 4 are fixed on base 2 by bolt 1.
Wherein, in the above-described embodiment, described elastic element is fixedly connected with block 6.
Wherein, in the above-described embodiment, described elastic element is butterfly spring group 3, and the free height of described butterfly spring group 3 is greater than the height of described mandrel 10, and one end of butterfly spring group 3 contiguous blocks 6 is fixed on block 6.
Wherein, in the above-described embodiment, described block 6 is T-shaped.
Wherein, in the above-described embodiment, on described base 2, be equipped with 4 for the bolt hole 8 of fixed bumper base 2, as shown in Figure 3.During use, by bolt, buffer base 2 is fixed on apparatus body, and then buffer is fixed on apparatus body.
