Technical scheme more than adopting, the elasticity needle is in hidden state under the effect of hoop to be located first empty system groove, will by the conveyer this moment the utility model discloses in sending into the living body, make the hoop retreat after that, elasticity needle auto-eject is the open mode, then moves down through the conveyer the utility model discloses, make the elasticity needle penetrate the living body, rethread conveyer makes hoop oppression elasticity needle get into hidden state again, and the living body that is passed by the elasticity needle simultaneously gets into first empty system groove, has so both realized the fixed of living body, reaches the purpose of design and actual effect. Therefore, on one hand, the utility model has the advantages of few parts, simple structure and low production cost; on the other hand, the utility model discloses it is easy and simple to handle, can not take place to wear to be impenetrable or dislocation phenomenon, also not have the risk that drops, fixed success rate is high, and the stability of product is good.
Preferably, the first hollow groove extends downwards from the upper part of the side wall of the base body, and the elastic needle is connected to the upper end of the first hollow groove close to the notch.
Preferably, a second dummy groove is formed in a groove bottom of an upper portion of the first dummy groove.
Preferably, the second dummy groove has a deepest middle portion, and the depth gradually decreases from the middle portion toward the upper and lower ends.
Preferably, the elastic needle is opened with an angle of 10-20 degrees with the long axis of the base body.
Preferably, the elastic needle is made of a titanium alloy.
Preferably, the hoop is annular and made of metal.
Has the advantages that: the utility model is not only simple in structure, spare part is few, and parts machining is easy, and is with low costs, easy assembly, and easy and simple to handle moreover, the reliability and the stability of product are good, can reach 100% effective success rate.

Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in fig. 1 and 2, the present invention is composed of a base body 1, an elastic needle 2, and a hoop 3. Wherein, the basal body 1 is an ellipsoid structure, so as to be capable of automatically guiding when entering a living body and reduce the uncomfortable feeling when entering the living body as much as possible. The substrate 1 may be made of metal or nonmetal, the material may be determined according to actual needs, and the embodiment is preferably plastic. The side wall of the base body 1 is provided with a first dummy groove 11, the first dummy groove 11 extends downward from the upper part of the side wall of the base body 1, and the first dummy groove 11 is in the same direction as the long axis direction of the base body 1. A second idle groove 12 is formed in the groove bottom of the upper portion of the first idle groove 11, the middle of the second idle groove 12 is deepest, and the depth of the second idle groove 12 gradually decreases from the middle to the upper end and the lower end.
As shown in fig. 1 and 2, an elastic needle 2 is arranged on a base body 1, the upper end of the elastic needle 2 is fixedly connected with the base body 1, the connection position is located at the upper end of a first vacant groove 11 close to a notch, and the rest part of the elastic needle 2 is suspended. The elastic needle 2 is preferably made of titanium alloy, and the material of the elastic needle 2 can be replaced by other metals according to actual needs. The elastic needle 2 has two states of opening and hiding, and an included angle of 10-20 degrees is formed between the elastic needle 2 and the long axis of the base body 1 when the elastic needle 2 is opened. The elastic needle 2 is hidden and positioned in the first hollow groove 11 and positioned by a hoop 3 sleeved on the base body 1. The hoop 3 is annular and made of metal.
The working principle of the utility model is as follows:
the utility model discloses need realize the live body with the help of the conveyer and fix, the conveyer has sleeve pipe 5 and stay cord 6, at first pack the utility model discloses the upper portion of base member 1 into sleeve pipe 5, the top of base member 1 and stay cord 6 fixed connection, and hoop 3 is near the terminal surface of sleeve pipe 5, hoop 3 ring cover is on base member 1 and elastic needle 2, makes elastic needle 2 be in hidden state, and is located first vacant groove 11, at this moment send the utility model into live body 4 by the conveyer (see figure 3), then promote stay cord 6 downwards, make base member 1 move downwards relative to sleeve pipe 5 and hoop 3, the pressure that hoop 3 acted on elastic needle 2 disappears, elastic needle 2 pops out under self elasticity and is the open mode (see figure 4), then move downwards through the conveyer the utility model discloses, make elastic needle 2 penetrate live body 4 (see figure 5), again pull stay cord 6 upwards, make base member 1 to sleeve pipe 5 internal motion, hoop 3 oppresses elasticity needle 2 and reenters hidden state, and the live body that is passed by elasticity needle 2 simultaneously gets into in first empty system groove 11 and the empty system groove 12 of second (see fig. 6), continues to force upwards to stimulate stay cord 6, makes stay cord 6 fracture, and the fracture position is close to the junction with base member 1 (see fig. 7), withdraws from the live body 4 with the conveyer at last, makes the utility model discloses fix to in the live body 4 (see fig. 8, fig. 9), can reach the purpose of design and actual effect.
The foregoing has described in detail preferred embodiments of the present invention.
