[specific embodiment]

It is further described below in conjunction with the vibration absorber of attached drawing hand-held vibrating spear a kind of to the utility model:

For the ease of understanding the utility model, in the following with reference to the drawings and specific embodiments, the utility model is carried out more detailed Thin explanation.

The attached drawing of this specification is schematic diagram, aids in illustrating the design of the utility model, it is schematically indicated each section Shape and its correlation.It note that for the ease of clearly showing the structure of each component of the utility model embodiment, respectively It is not drawn according to identical ratio between attached drawing.Identical reference marker is for indicating identical part.Below in conjunction with attached drawing The principles of the present invention and feature are described, example is served only for explaining the utility model, is not intended to limit this The range of utility model.

As shown, a kind of vibration absorber of hand-held vibrating spear, including hand-held part and multiple stop collars, the hand-held part 1 Including annular hand grip 11 and transition rings 12, the annular hand grip 11 and transition rings 12 are in same center line.The stop collar includes Upper limit ring 31, middle stop collar 32 and lower limit ring 33, the upper limit ring 31, middle stop collar 32 and lower limit ring 33 and transition Ring 12 is in same center line, and the middle stop collar 32 is Chong Die with the center of transition rings 12, and the upper limit ring 31 is located at transition rings 12 top, the lower limit ring 33 is in the lower section of transition rings 12.

More specifically, the annular hand grip 11 is fixedly connected with transition rings 12 by a plurality of connection strap 13, in the present embodiment Preferred forms be: using 4 connection straps 13, the connection strap 13 is evenly distributed setting around 12 central axis of transition rings.

More specifically, upper limit ring 31, middle stop collar 32 and lower limit ring 33 pass through respective bullet with transition rings 12 Property the connection of component 2 to forming vibration-proof structure.The preferred forms of the present embodiment are: respective elastic parts 2 includes 4 Spring, upper limit ring 31, middle stop collar 32 and lower limit ring 33 are connected by respective 4 springs with transition rings 12, respectively 4 springs be averagely arranged around the central axis of transition rings 12.

More specifically, the upper limit ring 31, middle stop collar 32 and lower limit ring 33 are all made of lock tube ring.It can pass through Movable screw adjusts lock tube ring diameter, to achieve the purpose that locking.Middle stop collar 32 is used for 11 position of stationary ring handle, on Stop collar 31 and lower limit ring 33 can prevent whole device from loosening after locking.

More specifically, the hand-held part is light aluminum alloy structure, and there are certain between annular hand grip 11 and transition rings 12 Distance is to guarantee that both hands can hold annular hand grip 11.

The work step of the utility model:

The concrete operating principle of the utility model are as follows: before operation of vibrating, vibrating spear is sequentially passed through into upper limit ring 31, middle limit Position ring 32 and lower limit ring 33 because middle stop collar 32 it is confirmed that ring-shaped handle 11 position, need to be by middle stop collar 32 It is locked after being adjusted to suitable position, then adjusts upper limit ring 31, lower limit ring 33 makes elastic parts 2 be in tension state, lock Tight upper limit ring 31 and lower limit ring 33.When work, vibrating spear can one man operation, handle is held by worker to carry out the work that vibrates Industry.It in process of vibrating, is separated between ring-shaped handle 11 and vibrating spear by elastic parts 2, the high-frequency vibration generated by vibrating spear Major part can be absorbed by elastic parts 2, and worker will not be influenced when operating vibrating spear by vibrating spear high-frequency vibration.

The preferred embodiment of the utility model is given in attached drawing.But the utility model can be with many different shapes Formula is realized, however it is not limited to this specification described embodiment.On the contrary, purpose of providing these embodiments is makes to this reality Understanding with novel disclosure is more thorough and comprehensive.
