DESCRIPTION OF EMBODIMENTS

[0033] The following are specific embodiments of the present disclosure and the accompanying drawings to further describe the technical solutions of the present disclosure, but the present disclosure is not limited to these embodiments.

Example 1

[0034] As shown in FIGS. 1 to 4, a telescopic structure for an electrotome capable of evacuating smoke may include an electrotome pencil body 1, the interior of the electrotome pencil body 1 may be hollow and one end may be provided with an opening. The opening end of the electrotome pencil body 1 may be provided with a limit connection part 2. A collar 3 may be sleeved outside the limit connection part 2, and an elastic limiter 4 may be provided between the limit connection part 2 and the collar 3. The telescopic structure for an electrotome capable of evacuating smoke may also include a channel 6 which runs through the collar 3 and the elastic limiter 4 in sequence and communicates with the inside of the electrotome pencil body 1.

[0035] A limit block 21 may be provided at the end of the limit connection part 2 away from the electrotome pencil body 1.

[0036] The limit block 21 may be in in contact with the elastic limiter 4 at one end away from the electrotome pencil body 1.

[0037] The channel provided at the electrotome pencil body 1, the collar 3 and the elastic limiter 4 may be provided with a smoking pipe 5.

[0038] The above-mentioned smoking pipe realizes retractility and positioning through the change of the aperture size of the channel on the elastic limiter by the user during use.

[0039] A protrusion 31 may be provided on the inner side of the rear end of the collar 3, and the inner side surface of the protrusion 31 may be in contact with the rear end surface of the limit block 21.

[0040] The collar 3 may be provided with a limit groove 32 for installing the limit connection part 2, and the spacing between the front end surface and the rear end surface of the limit groove 32 may be larger than that between the front end surface and the rear end surface of the limit block 21.

[0041] The collar 3 may be provided with a mounting groove 33 for mounting the elastic limiter 4. The mounting groove 33 may be 0-1 cm, preferably 0.1 cm, away from the front end surface of the limit groove 32. In another embodiment, the mounting groove 33 may be 0.2 cm away from the front end surface of the limit groove 32. In yet another embodiment, the mounting groove 33 may be 0.3 cm away from the front end surface of the limit groove 32.

[0042] The elastic limiter 4 can be annular, the longitudinal section of the elastic limiter 4 can be concave arc, and the channel through which the smoking pipe 5 can pass may be located at the center of the elastic limiter 4.

[0043] The collar 3 may include a collar body 34 and a collar inner sleeve 35. The collar inner sleeve 35 may be clamped on the inner side of the collar body 34. Between the rear side surface of the collar body 34 and the front end surface of the collar inner sleeve 35, an elastic limiter 4 may be provided.

[0044] The collar inner sleeve 35 may be provided with a limit part 351 which is protruded inward and is adapted to be matched with the limit connection part 2.

[0045] The specific embodiments described herein are merely illustrative of the spirit of the present disclosure. Those skilled in the art to which the present disclosure pertains can make various modifications or additions to the described specific embodiments or substitute in similar manners, but will not deviate from the spirit of the present disclosure or go beyond the definitions of the appended claims.
