Detailed ways

The technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model.

Shown in conjunction with Fig. 1, Fig. 2 and Fig. 3, the mouth mirror disclosed by the utility model includes a mirror holder 1, a mirror rod 2 and a mirror handle 3, and one end of the mirror rod 2 is connected with the mirror holder 1, The other end is connected with the mirror handle 3; the mirror holder 2 is provided with a lens 11 for observing the inside of the oral cavity; the end of the mirror handle 3 connected with the mirror rod 2 is provided with a first light source 323, The back side of the mirror holder 2 is provided with a second light source 13, and the first light source 323 and the second light source 13 illuminate the inside of the oral cavity under the condition of power on, so as to facilitate the observation of abnormal conditions inside the oral cavity. An insertion end 21 is provided, and the two sides of the insertion end 21 are symmetrically provided with a raised portion 211 extending outward along the side wall of the insertion end 21, and an insertion groove 12 is arranged on the mirror holder 1, and the inner wall of the insertion groove 12 Both sides are symmetrically provided with grooves (not shown in the figure), the insertion end 21 can be installed inside the insertion groove 12, and the protrusion 211 and the groove are engaged, and the mirror rod 2 and the mirror holder 1 are in the protrusion. 211 and the groove rotate up and down, when the mirror rod 2 rotates toward the mirror holder 1, the angle between the mirror holder 1 and the mirror rod 2 decreases, when the mirror rod 2 rotates away from the mirror holder 1 , the angle between the mirror holder 1 and the mirror rod 2 increases.

Preferably, in order to better fix the size of the angle formed between the mirror holder 1 and the mirror rod 2, several protrusions 2111 are provided on the outer peripheral side wall of the raised portion 211, and several protrusions 2111 are arranged on the inner side wall of the groove. There are several card slots (not shown in the figure) on the circumferential direction of the frame, and the protrusion 2111 can be installed in the card slots, and plays a role in fixing the mirror holder 1 and the mirror rod 2, so that the mirror holder 1 and the mirror rod 2 The angle between them is not easily changed by external force. Under the action of sufficient force, the protrusion 2111 can slide into the next slot from the previous slot, which not only adjusts the angle between the mirror rod 2 and the mirror holder 1, but also fixes the angle more.

As shown in Figure 1, the mirror handle 3 includes a front housing 32 and a rear housing 31, the interior of the two housings is hollow, and an internal thread (not shown) is provided at one end of the front housing 32, and The inside of one end of the housing 31 is provided with an external thread (not shown), the front housing 32 and the rear housing 31 are connected together by internal and external threads, and a chamber is formed inside, and a battery holder 33 is provided inside the chamber, and the battery holder 33 is provided inside the chamber. Holder 33 is used for installing the power supply of battery formation light source, and battery holder is respectively connected with first light source 323 by first power cord (not shown in the figure), connects with second power source (not shown in figure) by second power cord (not shown in figure). shown), a power switch 321 is provided on the front housing 32. When the power switch 321 is pushed upward, the first power line is connected to the power supply, and the first light source 323 lights up; when the power switch 321 is moved downward , the second power line is connected to the power supply, and the second light source 13 lights up; when the power switch 321 returns to the middle position, the light sources are all turned off.

In addition, the front case 32 and the rear case 31 may also be connected in a plug-in manner, or in a snap-in manner.
