Specifically, a pushing device 4 is arranged between the clamping ring 1 and the rotating ring 2, the pushing device 4 is arranged at a position corresponding to the elastic part 3, and the pushing device 4 is matched with the elastic part 3 for use. The elastic elements 3 can conform to the arc of the gripping ring 1 so that the cigarettes 9 are not obstructed during insertion.

In the embodiment of the invention, the pushing device 4 and the elastic element 3 have the function relation of generating elastic deformation by pressing and also have the function relation of generating elastic deformation by tensioning, so that the deformation of the elastic element 3 caused by long-term use can be effectively alleviated.

Specifically, taking fig. 1 as an example, when the rotating ring 2 rotates clockwise, the elastic member 3 is pulled to the outside of the clamping ring 1, so as to generate elastic deformation; when the rotating ring 2 rotates counterclockwise, the elastic member 3 is pressed toward the inside of the clamp ring 1, thereby being elastically deformed.

Based on the demand when a cigarette 9 inserts, can freely adjust the deformation direction and the degree of elastic component 3 on the grip ring 1 to make a cigarette 9 can insert smoothly and accomplish the centre gripping.

In the embodiment of the invention, the position of the clamping ring 1 can be fixed, the rotating ring 2 is sleeved outside the clamping ring 1, and the rotating ring 2 can rotate, so that the pushing device 4 can extrude and tighten the elastic part 3. A plurality of elastic parts 3 can be opened on the ring arm of grip ring 1, and elastic part 3 can surround formula evenly distributed for elastic part 3 can carry out the centre gripping to a cigarette 9 more from a plurality of directions when producing elastic deformation.

In the embodiment of the present invention, the pushing device 4 comprises a supporting member 31 and a pushing block 21, wherein the supporting member 31 is obliquely arranged outside the elastic end; the inner ring wall of the rotating ring 2 is provided with a pushing block 21 at the position corresponding to the elastic element 3, and the pushing block 21 and the rotating ring 2 rotate synchronously. The position of the clamping ring 1 is fixed, relative rotation can be generated between the clamping ring 1 and the rotating ring 2, and the coaxial state is kept during rotation.

Specifically, referring to fig. 1 and 2, the supporting member 31 is inclined toward the fixed end of the elastic member 3, the end of the supporting member 31 is provided with a pawl, and the top of the pawl forms a butt-joint inclined surface 42; the pushing block 21 is provided with a pushing groove corresponding to the inverted tooth, so that the end of the supporting piece 31 and the inverted tooth can be butted to the pushing groove, and the supporting piece 31 and the pushing groove form a clamping effect in the rotating direction of the rotating ring 2.

Furthermore, the front side wall of the pushing groove protrudes backwards to form a vertex angle, and the vertex angle and the pawl can be mutually butted and occluded, so that the vertex angle can be hung and connected with the pawl; if the rotating ring 2 rotates continuously in the clockwise direction, the pushing groove can pull the elastic member 3 to generate elastic deformation towards the outer side of the clamping ring 1.

The clamping ring 1 is embedded into the upper end of the heating cavity annular wall of the smoking set 7 and is coaxially arranged, and the deformation of the elastic piece 3 is not affected. The inner diameter of the clamping ring 1 is the same as the diameter of the heating cavity, so that the cigarette 9 can be smoothly inserted. The depth of the heating chamber is slightly greater than the length of the tobacco segment 92 so that the gripping ring 1 can grip the tobacco segment 91.

The rotating ring 2 is statically arranged outside the clamping ring 1 and can rotate, and the rotating block 5 on the rotating ring 2 is exposed to the outside of the shell of the smoking set 7. Specifically, a rotation groove 74 may be formed in the housing of the smoking set 7, the rotation block 5 is disposed in the rotation groove 74, and the rotation groove 74 provides a space required for the rotation of the rotation block 5, so that the rotation range of the rotation block 5 is limited by the rotation groove 74.

The rotating block 5 is pushed to synchronously limit the rotating range of the rotating ring 2, so that the displacement generated by the relative rotation between the rotating ring 2 and the clamping ring 1 is related to the rotating range, and the displacement can be adjusted by adjusting the rotating range, thereby adjusting the strength of the elastic deformation generated by the elastic piece 3 when the pushing device 4 pushes the elastic piece 3.

Specifically, referring to fig. 5, when the rotating block 5 rotates clockwise, that is, the elastic member 3 elastically deforms toward the inner side of the clamping ring 1, the clockwise rotation space of the rotating groove 74 is larger; when the rotation block 5 rotates in the reverse direction, that is, the elastic member 3 elastically deforms to the outside of the clamp ring 1, the reverse rotation space of the rotation groove 74 is small. It will be appreciated that the amount of rotation space is relative.

The cis-position rotating space is large, and the application range of the cigarette 9 can be matched based on the limit degree of elastic deformation of the elastic piece 3. When the rotation is performed in the reverse direction, the elastic member 3 can be tensioned to elastically deform the outer side of the clamp ring 1, and the excessive extrusion of the elastic member 3 can be alleviated.

As an embodiment, the limiting buckle may include a first wedge and a second wedge, which are respectively disposed on the rotation block 5 and the rotation groove 74, and are used in cooperation with each other, as shown in fig. 5.
