Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Embodiment one, by figure 1, figure 2 and figure 3 give, the utility model discloses a drum 1, spout 2 has been seted up to drum 1's inside equidistance, drum 1's top mid-mounting has damping spring 3, can play the effect of one-level buffering through damping spring 3, base 4 is installed to damping spring 3's bottom, base 4's outer wall equidistance fixed mounting has lower slider 5,

lower slider

5 and 2 sliding connection of spout, damping spring 6 is installed to drum 1's inside still equidistance, can play the effect of second grade buffering through damping spring 6, ring body 7 is installed to damping spring 6's bottom, ring body 7's outer wall equidistance fixed mounting has last slider 8,

last slider

8 and 2 sliding connection of spout, be convenient for install ring body 7.

In the second embodiment, on the basis of the first embodiment, the buffer block 9 is installed at the top end of the sliding chute 2, and the buffer block 9 is made of rubber materials and can play a role of three-level buffering through the buffer block 9.

In the third embodiment, on the basis of the first embodiment, the base 4 is located at the bottom end of the ring body 7, the lower cushion pad 11 is bonded to the top end of the base 4, and the upper cushion pad 12 is bonded to the bottom end of the ring body 7, so that the base 4 and the ring body 7 can be prevented from directly colliding.

In the fourth embodiment, on the basis of the first embodiment, a screw hole 13 is formed in the base 4, a punch 14 is connected to the screw hole 13 through a thread, and a nut 15 is connected to the top of the punch 14 through a thread, so that the punch 14 can be conveniently mounted.

Fifth, on the basis of the first embodiment, the damping spring 3 is inserted in the middle of the ring body 7, the damping springs 6 are uniformly distributed outside the damping spring 3, and the size of the damping spring 6 is smaller than that of the damping spring 3, so that the damping spring 3 is convenient to mount.
