[0002] At present, during dental treatment, some dental handle structures require the handle head to be inserted into the oral cavity for operation. Due to the small operating space in the oral cavity, the dental handle is very inconvenient to use. For example, when a dentist uses a dental handle, he often needs to observe the situation in the oral cavity while performing root canal preparation. At this time, if the target root canal cannot be found quickly and in time, the dental handle needs to be stopped and moved away to see clearly, which is very inconvenient to use. It is difficult for the doctor to see the situation of the operating part with the naked eye. In order to be able to see the situation in the oral cavity and quickly find the target position, a camera is generally installed on the handle head to observe the oral situation through the camera.

The clamping cavity 314 is adapted to the head housing 21, and the head housing 21 is clamped in the clamping cavity 314. In this embodiment, the buckle body 311, the first clamp arm 312, and the second clamp arm 313 can be detachably connected or integrally formed. Preferably, the buckle body 311, the first clamp arm 312, and the second clamp arm 313 are integrally formed. The integrally formed setting is convenient for improving the structural stability of the buckle 31.

[0049] For further information, please refer to Figures 4 to 7 A first fixing part 315 is provided on the first clamping arm 312 and / or the second clamping arm 313. The first fixing part 315 is located on the inner wall of the clamping cavity 314. A second fixing part 22 matching with the first fixing part 315 is provided on the outer wall of the head shell 21. The cooperation between the first fixing part 315 and the second fixing part 22 makes the fixing of the snap part 31 on the head shell 21 more firmly and not easy to fall off.

[0050] In a specific embodiment, one of the first fixing member 315 and the second fixing member 22 is an insert block, and the other is a slot. The insert block is inserted into the slot. After the machine head 2 is fixed in the clamping cavity 314, the insert block is inserted into the slot, and the first clamp arm 312 and / or the second clamp arm 313 are more firmly fixed on the machine head housing 21 and are not easy to fall off.

In other embodiments, the insert block and the slot can also be other shapes, which are not limited here.

[0051] In another specific embodiment, please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7 The first clamp arm 312 and the second clamp arm 313 can be arc-shaped structures, and the first clamp arm 312 and the second clamp arm 313 both have an arc-shaped clamping surface 316. The head shell 21 can be an arc-shaped shell, and the first fixing member 315 is arranged on the arc-shaped clamping surface 316; specifically, the arc-shaped clamping surface 316 can increase the contact area and friction between the head shell 21 and the first clamp arm 312 and the second clamp arm 313, thereby improving the firmness of the clamping; in other embodiments, the first clamp arm 312, the second clamp arm 313, and the head shell 21 can also be other shapes, which are not limited here.

[0052] In another specific embodiment, the first clamp arm 312 and the second clamp arm 313 are both elastic structures. Specifically, the first clamp arm 312 and the second clamp arm 313 can be elastic arc-shaped arms, the head housing 21 is an arc-shaped housing, and the end of the clamping cavity 314 facing the head housing 21 has an insertion port 3141, and the width of the insertion port 3141 is smaller than the radial width of the head housing 21. When the head housing 21 is inserted into the clamping cavity 314, the head housing 21 abuts against the first clamp arm 312 and the second clamp arm 313 on both sides of the insertion port 3141 and the first clamp arm 3141 is engaged with the first clamp arm 312 and the second clamp arm 313 on both sides of the head housing 21. 12 and the second clamp arm 313 undergo elastic deformation. After the width of the insertion port 3141 increases, the head shell 21 can be inserted into the clamping cavity 314 through the insertion port 3141. After the head shell 21 is fixed in the clamping cavity 314, the first clamp arm 312 and the second clamp arm 313 restore the elastic deformation and fit in contact with the head shell 21. The first clamp arm 312 and the second clamp arm 313 clamp the head shell 21. The width of the insertion port 3141 is smaller than the radial width of the head shell 21, which can prevent the head shell 21 from escaping from the clamping cavity 314 from the insertion port 3141.
