It is preferred that, the hoop piece is multiple, and multiple hoop pieces are placed equidistant.

By using above-mentioned technical proposal, by the way that multiple circumferential band pieces are equipped with, the flange of different-diameter is set in hoop When can still be fitted with flange round edge.

It is preferred that, punching press is fluted on the hoop piece, and the strap is fixedly welded on the side of hoop piece protrusion.

By using above-mentioned technical proposal, because groove is to be stamped and formed out on hoop piece, so hoop piece has good shape Change ability, can be with strap flexural deformation.

It is preferred that, sleeve two is cased with the sleeve one, one end of sleeve two offers the depth with the form fit of sleeve one Kong Yi, the other end offers the deep hole two coordinated with nut shape, and deep hole one is communicated with deep hole two, and the end of sleeve two, which is provided with, to be used for The handle of turnbarrel two.

By using above-mentioned technical proposal, opened up, sleeve two can be placed on sleeve one by deep hole one, deep hole two, Simultaneously by the cooperation of nut and deep hole two, sleeve can be enclosed on nut, nut is turned during convenient use handle turnbarrel.

It is preferred that, the handle is the steel pole being fixed on sleeve two, and sleeve two is provided with through hole close to end, and steel pole hangs down Directly it is fixedly welded in sleeve two in through hole.

By using above-mentioned technical proposal, by setting handle in the end of sleeve two, increase the arm of force, be using less power Rotary nut, so as to reach the effect for making strap tighten up or unclamp.

It is preferred that, it is described to tighten up block one and to tighten up block two be short steel pipes.

By using above-mentioned technical proposal, gather materials on the spot, manufacturing cost is cheap, and steel pipe is hollow pipe, convenient punching peace Sleeved one, quality is also lighter.

In summary, the utility model has the advantages that：

It can facilitate and lid is dismounted on hopper, or hopper is removably attachable in equipment, the locking device also has The characteristics of adjusting banding degree, and it is easy to adjust laborsaving.
