In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a medical treatment cavity rivet for walking stick, including the rivet body, the rivet body is including rivet cap and the rivet bar of coaxial setting, the one end that the rivet cap was kept away from to the rivet bar is provided with the riveting opening demountable installation has the reinforcement subassembly in the riveting opening be provided with the bump on the circumference wall of rivet bar.
As the utility model discloses preferred scheme, consolidate the subassembly including setting up the screw hole in riveting opening bottom screw hole female connection has the reinforcing bolt, the bolt head of reinforcing bolt is greater than the diameter of rivet bar.
As the preferred scheme of the utility model, the bottom of riveting pressure opening is conical structure.
As the preferable proposal of the utility model, the height of the salient point is 0.1-0.4mm.
As the utility model discloses preferred scheme, the rivet cap is semi-circular rivet cap.
As a preferred aspect of the present invention, the ratio of the diameter of the rivet pressing opening to the diameter of the rivet stem is 0.8.
As the utility model discloses preferred scheme, the rivet cap adopts aluminum alloy material an organic whole to make with the rivet bar.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the reinforcing component is arranged at the riveting opening, so that after the riveting opening is riveted and bloomed, the reinforcing component can be used for reinforcing and connecting the riveting opening, the stability after riveting is further enhanced, and the side corner and the loop bar can be firmly connected;
2. through the setting of bump, this bump can be hung and establish on the hole side of turning the foot of side to play certain supporting role, prevent that the rivet body accident from falling out, the subsequent riveting work of being convenient for.

Detailed Description
The following detailed description provides many different embodiments or examples for implementing the invention. Of course, these are merely embodiments or examples and are not intended to be limiting. In addition, repeated reference numbers, such as repeated numbers and/or letters, may be used in various embodiments. These iterations are for simplicity and clarity of the description of the present invention and do not represent a particular relationship between the various embodiments and/or structures discussed.
The invention will be further described with reference to the following description of the drawings and detailed description: the hollow rivet for the medical crutch shown in fig. 1 to 3 comprises a rivet body 10, wherein the rivet body 10 comprises a rivet cap 1 and a rivet stem 2 which are coaxially arranged, a riveting opening 3 is arranged at one end, far away from the rivet cap 1, of the rivet stem 2, a reinforcing component is detachably mounted in the riveting opening 3, and a convex point 4 is arranged on the circumferential wall surface of the rivet stem 2.
