It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for descriptive purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 4, a safety protection type pearl tail comprises a fixing portion 21 fixed with an outer round bone 1, a pearl tail sleeve 22 is arranged on the outer side of the fixing portion 21, the outer side surface of the pearl tail sleeve 22 is an arc surface, an included angle between a contact surface between the pearl tail sleeve 22 and the fixing portion 21 and the outer round bone 1 is 40-50 °, specifically, in this embodiment, the included angle between the contact surface between the pearl tail sleeve 22 and the fixing portion 21 and the outer round bone 1 is 45 °.

After the umbrella is opened, the excircle rib 1 of the umbrella is not parallel or vertical to the middle rod, but forms a certain included angle,

the included angle between the contact surface between the bead tail sleeve 22 of the bead tail 2 and the fixing part 21 and the outer round bone 1 is set to be in an inclined state, so that the bead tail sleeve 22 of the bead tail 2 has certain directivity, the arc surface of the bead tail sleeve 22 faces outwards, and the arc surface can be increased under the condition that the bead tail 2 is not enlarged, so that the contact area with the outside is increased, and the danger in the use process is reduced.

At this moment, for the pearl tail 2, mainly include fixed part 21 and pearl tail cover 22, for fixed part 21 and pearl tail cover 22, both can adopt integrated into one piece, also can adopt the components of a whole that can function independently shaping fixed, when adopting integrated into one piece, through designing relevant mould, produce it through one shot forming, it is simple and convenient.

For the separate molding, the fixing portion 21 and the bead tail sleeve 22 are separately produced and then fixed therebetween, in this embodiment, the bead tail sleeve 22 is connected with the fixing portion 21 through a screw thread.

Specifically, at this time, an inclined connecting portion is arranged on the side where the fixing portion 21 is connected with the bead tail sleeve 22, and a thread is arranged on the outer side surface of the connecting portion. One side of the bead tail sleeve 22, which is back to the arc surface, is provided with a connecting surface which is in contact with the connecting part, and the connecting surface at the moment is provided with threads, so that the bead tail sleeve 22 is fixedly connected with the fixing part 21 through threaded connection.

At this time, the side of the bead tail sleeve 22 connected to the connecting portion is a plane (i.e., a connecting surface), and the arc surface is located on the upper side of the plane. After the bead tail sleeve 22 and the fixing part 21 are fixed, the arc surface of the bead tail sleeve 22 faces outwards, so that the arc surface faces outwards in the using process of the umbrella, and the danger in the using process can be reduced.

For the fixation between the bead tail 2 and the outer round bone 1, in this embodiment, the fixing portion 21 is a fixing sleeve 23 adapted to the outer round bone 1, and the fixing sleeve 23 is sleeved on the outer side of the outer round bone 1. The fixing sleeve 23 is a hole at the position of the fixing portion 21, and the fixing portion 21 is fitted to the outer side of the outer round bone 1 through the hole, thereby fixing the bead tail 2 to the outer round bone 1.
