the stress part 200B is connected with the polycondensation heating body 122 through a stress belt 230, and the stress belt 230 slides in the slot 1111.

In addition, as shown in fig. 9, a connecting disc 130 is disposed on the outer wall of the heating ring 110 corresponding to the hard portion 200C, an adapter 131 is disposed on the outer side of the connecting disc 130, the hard portion 200C is rotatably connected to the adapter 131, a bump 132 is disposed on the inner side of the adapter 131, a limiting hole 240 is disposed on the outer side of the hard portion 200C, and two limiting holes 240 are opened, one of which is clamped with the convex point 132 when the hard part 200C is in a vertical state, thereby limiting the corresponding hair side belt body 210 and hook side belt body 220, when the acupuncture is needed, the bonded hair side belt body 210 and hook side belt body 220 are rotated, then the force-bearing belt 230 is matched with the polycondensation heating body 122 to drive the opening of the heating ring 110 to tilt, thus, a cavity for needle insertion is formed, and at the moment, the convex point 132 is clamped by the other limiting hole 240, so that the cavity is kept stable, and needle insertion is carried out in the cavity at the moment.

It should be noted that the hard portion 200C has a hard structure and also has a purpose of stably rotating around the rotation joint 131.

Example 3

Considering that disinfection is needed before needle insertion, in order to utilize the opening of the heating ring 110, please refer to fig. 6 and 7, the supporting plate 112 is disposed at one end of the opening of the heating ring 110, the bonding mechanism 300 is disposed between the two supporting plates 112, please refer to fig. 5, the bonding mechanism 300 includes a bonding tape 310, a hot melt interlayer 320 is disposed at the bottom of the middle portion of the bonding tape 310, a closed alcohol cavity 330 is formed between the hot melt interlayer 320 and the bonding tape 310, the alcohol cavity 330 is pre-filled with disinfection alcohol, and cotton 340 is disposed at the bottom of the hot melt interlayer 320.

The working principle is as follows:

after the heating ring 110 is sleeved on the arm, the adhesive tape 310 is adhered to the supporting plate 112, and after the hair side belt body 210 and the hook side belt body 220 are adhered, the polycondensation heating body 122 at the opening of the heating ring 110 is gathered, namely, the principle of the embodiment 1 is that the opening is rapidly heated, then the hot melting interlayer 320 is melted, the disinfection alcohol in the alcohol cavity 330 is immersed in the cotton 340, then the cotton 340 is driven to wipe the skin in the tilting process of the heating ring 110, so that the skin is disinfected, and then the needle can be directly pricked after the tilting;

and the environment of heating is utilized, so that the cotton 340 can be isolated from the sterilized alcohol, and the sterilized alcohol is immersed into the cotton 340 when in use, thereby solving the problem that the alcohol is volatilized quickly in the cotton 340.

Example 4

Considering that the cotton 340 of example 3 can only perform the function of wiping and sterilizing alcohol, however, it is required to stop bleeding of the penetrated portion after the needle penetration, therefore, the present embodiment further utilizes the cotton 340, as shown in fig. 5 and 6, two isolation strips 350 are symmetrically disposed at the bottom of the splicing tape 310 and the cotton 340, bonding layer and cotton 340 of bonding sticky tape 310 bottom can all be kept apart like this, not only played the guard action, can also prevent that bonding sticky tape 310 from being taken place by the unable problem of using of bonding layer behind the extrusion, to being connected of bonding sticky tape 310 and fagging 112, this embodiment is provided with joint portion 1121 in the bottom of fagging 112, the one end that two median 350 contacted is provided with connector 351, please refer to fig. 8 and show, connector 351 is used for tearing joint portion 1121 joint behind median 350, thereby realized bonding sticky tape 310 and fagging 112 and be connected.

The working principle is as follows:

after the heating ring 110 is sleeved on the arm, the adhesive tape 310 is put on the supporting plate 112, then the isolating strip 350 is torn off to make the connecting head 351 be clamped into the clamping portion 1121, at this time, the adhesive tape 310 is connected with the supporting plate 112, then the hair side belt body 210 and the hook side belt body 220 are bonded to finish the wiping of the disinfection alcohol, then, the needle insertion is carried out, after the needle insertion is finished, the adhesion between the hair side belt body 210 and the hook side belt body 220 is removed, then the heating ring 110 is taken down, in the process, the cotton 340 is stressed to be attached to the needle insertion position, then the two ends of the adhesive tape 310 are gradually separated from the supporting plate 112, the isolation strip 350 is also driven by the clamping portion 1121 to separate from the adhesive tape 310, at this time, the adhesive layer of the adhesive tape 310 can be attached to the skin, so that the cotton 340 is fixed at the needle insertion position to stop bleeding, and the disinfecting alcohol in the cotton 340 is volatilized (the heating environment accelerates the volatilization of the disinfecting alcohol).

In addition, in order to stably place the adhesive tape 310 on the supporting plate 112, in this embodiment, the positioning hole 113 is formed in the outer wall of the heating ring 110 at the top of the supporting plate 112, and the positioning heads 311 are disposed at both ends of the adhesive tape 310, so that the positioning heads 311 can be inserted into the positioning holes 113 when the adhesive tape 310 is placed, thereby positioning the adhesive tape 310, improving the stability after placing the adhesive tape, and the positioning heads 311 are movably connected with the positioning holes 113, which does not affect the implementation of the above principle.

It is worth to say that, the hot melt interlayer 320 is composed of a hot melt part 321 and supporting parts 322 on two sides of the hot melt part, the hot melt part 321 can adopt EVA hot melt glue, and the supporting parts 322 are not heated to melt, so that the hot melt interlayer has a supporting effect on cotton, ensures that the cotton has a certain shape, and is more beneficial to wiping the needle pricking part by the cotton.

Example 5

In view of the poor stability of the adhesive tape 310 after natural adhesion with the skin, this embodiment is improved on the basis of embodiment 4, please refer to fig. 10, in which an adapting cavity 114 is formed at one end of the heating ring 110 at the opening, the functional rack 140 in a bent state is rotatably connected in the adapting cavity 114, a torsion spring is disposed at the adapting position between the functional rack 140 and the adapting cavity 114, a roller 141 is disposed at one end of the functional rack 140 opposite to the adapting position, and the roller 141 is rotatably connected with the functional rack 140.
