As a further scheme of the invention, the use method of the invention comprises the following steps:

use of instrument tip directed against spacer layer

Before the pointed separation layer of the instrument is sleeved, firstly, after the pointed end of the instrument is disinfected, the two fingers hook the detachable pull block, one finger pushes the top of the pointed separation layer of the instrument downwards, at the moment, the hard support shell supports the pointed separation layer of the pointed end of the instrument, the penetration-preventing filling solid head has certain strength, the detachable pull block slides upwards along the edge of the pointed separation layer of the pointed end of the instrument, at the moment, the first rolling elastic ring shrinks due to the influence of the cambered surface caused by the closing structure of the pointed separation layer of the instrument, the distance between the two detachable pull blocks shrinks, and the soft connection opening bundling sleeve is influenced by the stretching of the first rolling elastic ring, so that the length of the soft connection opening bundling sleeve positioned below the hard support shell shrinks, and meanwhile, the soft connection opening bundling sleeve is limited by the end width of the hard support shell, and the bending closing surface of the soft connection opening bundling sleeve expands, and then make the pointed end of the apparatus point to the bore of the bottom of the spacer layer and expand, insert the pointed end into the hollow storage cavity at this moment, only need to loosen and dismantle the pulling block, the second contracting elastic ring receives the elastic force influence at this moment, take place the relative slip with the soft connection and restraint the oral cavity cover, receive the influence of wide mouth of the rigid support shell at the same time, make the contraction face of the soft connection and restrain the oral cavity cover extend downward, the first rolling elastic ring receives the tensile influence of the second contracting elastic ring, expand and slide downward, until the second contracting elastic ring surrounds apparatus, tool, the soft connection at this moment restrains the oral cavity cover and forms a positioning inclined plane, the first rolling elastic ring locates at the external flaring department that the pointed end of the apparatus points to the spacer layer at this moment, finish the closure of the pointed end, this way makes it more convenient to insert, the movements are simplified, avoid because the mouth should be laminated with the pointed end and cause the situation of inserting inconvenience, meanwhile, a limit cavity is formed in the tip, and the tip is more convenient to pull out;

matching limit of compressed air bag ring and extrusion limit balloon

When the soft connection binding port sleeve is in an opening state, the second contraction elastic ring is not in contact with the compression air bag ring, the compression air bag ring expands outwards, the extrusion limiting ball bag is in a closing state, the extrusion limiting ball bag is positioned at two sides close to the tip end, the extrusion limiting ball bag cannot obstruct the insertion of the tip end, when the soft connection binding port sleeve is released, the second contraction elastic ring and the soft connection binding port sleeve slide relatively, the second contraction elastic ring slides to the compression air bag ring to deform the compression air bag ring, gas is compressed and conveyed to the extrusion limiting ball bag through a communication pipe to expand the extrusion limiting ball bag, the tip end is positioned in an inner cavity of the instrument tip pointing to the separation layer, the extrusion limiting ball bag can expand to be positioned at two sides of the tip end to carry out secondary limiting on the tip end, and the stability of support is guaranteed;

hard support shell setting

The contraction end of the hard support shell is a horizontal plane, the two ends of the hard support shell are both fixed with connecting edge buffer rings, and the connecting edge buffer rings are mainly used for preventing the soft connecting tying sleeve from being torn due to over-small angle after the soft connecting tying sleeve is bent at the end part of the hard support shell, so that the transition of the soft connecting tying sleeve is smoother, and the use stability of the soft connecting tying sleeve is ensured;

cooperation of instrument tip horizontal spacer with instrument tip directional spacer

The end part of the horizontal separation layer at the tip end of the instrument is provided with a positioning storage groove, the top of the positioning storage groove is open, so that a limiting effect is provided for fixing the disassembling pulling block, the disassembling pulling block can be directly placed between the two positioning storage grooves, and the pointing separation layer at the tip end of the instrument is limited, so that the relative motion of the pointing separation layer at the tip end of the instrument and the horizontal separation layer at the tip end of the instrument caused by the movement of the instrument is avoided;

better application

The soft connection binding port sleeve and the hard support shell are integrally formed, the hard support shell is surrounded inside, the outer wall of the hard support shell and the inner wall of the hard support shell are provided with surrounding surfaces which are formed by the same materials as the penetration-preventing filling solid head and the soft connection binding port sleeve, and meanwhile, in order to avoid the closed condition caused by compression of the communicating pipe, the communicating pipe can adopt a pipeline with certain elasticity, so that even if the communicating pipe is subjected to bending compression, the closed condition is not generated, the air flow is blocked, and the situations that the compressed air bag ring and the extrusion limiting air bag cannot be normally closed or opened are avoided;

compared with the prior art, the invention has the beneficial effects that:

1. the tail end closing-in is formed by the pointed separation layer of the instrument, the flaring structure at the outer end is combined with the soft connection opening restraining sleeve, the pointed separation layer of the instrument forms a surrounding layer type three-dimensional space to be sleeved, the port of the soft connection opening restraining sleeve can be expanded when the instrument is used according to the condition, the soft connection opening restraining sleeve can still be easily opened by the pointed separation layer of the whole instrument through the arrangement of the detachable pulling block, after the pointed end is inserted into the hollow storage cavity, only the detachable pulling block needs to be loosened, at the moment, the second contraction elastic ring is influenced by the elastic force and slides relative to the soft connection opening restraining sleeve and is influenced by the wide opening of the hard support shell, the contraction surface of the soft connection opening restraining sleeve extends downwards, the first rolling elastic ring is influenced by the stretching of the second contraction elastic ring, the expansion sliding downwards occurs until the second contraction elastic ring is influenced by the instrument, After the tool is surrounded, the soft connection mouth bundling sleeve forms a positioning inclined plane, meanwhile, the first rolling elastic ring is located at an external flaring opening of the tip end of the instrument pointing to the separation layer, and the tip end is closed at the moment;

2. when releasing, the relative slip takes place for the second shrink elastic ring and the flexible coupling beam mouthful cover, the second shrink elastic ring slides to compressed air bag ring department, make compressed air bag ring take place deformation, gas compression, carry to extrusion spacing sacculus department through communicating pipe, make and extrude spacing sacculus inflation, and most advanced this moment is located the interior cavity of the most advanced directional separate layer of apparatus, it then can the inflation be located most advanced both sides to extrude spacing sacculus this moment, it is spacing to carry out the secondary to most advanced, the stability of the support of assurance.
