[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a ceramic heating body for a camera heating ring, comprising a hollow shell 5, a ceramic heating tube 10 installed in the shell 5, a sleeve 3 fixedly connected to the front end surface of the shell 5 for being sleeved on the outside of a camera lens barrel 4, a hollow locking cylinder 8 inserted into the inner side of the sleeve 3, a tightening cylinder 1 threadedly connected to the front side of the sleeve 3, an inverted cone 12 fixedly arranged on the outer side of the front end of the locking cylinder 8, a plurality of evenly distributed through grooves 11 are formed on the locking cylinder 8 and the inverted cone 12, a plug hole is formed on the inverted cone 12, and the inner diameter of the plug hole is the same as the inner diameter of the locking cylinder 8.

[0021] First, insert the camera lens barrel 4 into the sleeve 3, and fix the sleeve 3 in the camera lens barrel 4 by rotating the tightening cylinder 1, so that the ceramic heating tube 10 heats the camera lens barrel 4; by rotating the tightening cylinder 1, the tightening cylinder 1 enters the sleeve 3, and the inner side of the tightening cylinder 1 contacts the outer end surface of the front end of the inverted truncated cone 12, and the tightening cylinder 1 continues to rotate, so that the tightening cylinder 1 drives the outer side of the front end of the inverted truncated cone 12 to move inwardly toward the lens barrel 4, so that the sleeve 3 is fixed in the camera lens barrel 4 by the locking cylinder 8; the inverted truncated cone 12 and the locking cylinder 8 are equally divided by the through groove 11, so that the lens barrel 4 is clamped and fixed by the inverted truncated cone 12 and the locking cylinder 8.

[0022] A positioning ring 9 is fixedly connected to the inner wall of the sleeve 3 , and the positioning ring 9 is located at the rear side of the locking cylinder 8 .
