It should be noted that the first inclined surface 311 and the second inclined surface 321 are not necessarily thread inclined surfaces with more than 1 turn, but may be a part of one turn of thread inclined surfaces.
Specifically, when the first inclined surface 311 and the second inclined surface 321 are threaded inclined surfaces, the locking handle 310 and the pressing portion 320 can also be reversely self-locked as long as the tangent of the spiral angle of the first inclined surface 311 and the second inclined surface 321 is smaller than the maximum static friction factor between the first inclined surface 311 and the second inclined surface 321.
As shown in fig. 3, the turntable 220 is connected with a rotating shaft 210, and the rotating shaft 210 passes through the locking handle 310 and the pressing part 320; the rotating shaft 210 is used for driving the rotating disc 220 to rotate, the locking handle 310 and the pressing portion 320 are sleeved on the outer ring of the rotating shaft 210, and the locking handle 310 and the rotating shaft 210 can coaxially and independently rotate.
As shown in fig. 1, in order to facilitate the rotation of the driving shaft 210, a rotation handle 240 is connected to the shaft 210, and the rotation handle 240 is located outside the housing 100.
As shown in fig. 2 and 3, a connecting portion 330 is disposed between the pressing portion 320 and the turntable 220, the connecting portion 330 is rotatably connected to the pressing portion 320, the connecting portion 330 can abut against the turntable 220 under the action of the pressing portion 320, and at this time, the connecting portion 330 is pressed by the pressing portion 320 to press the turntable 220 downward, so as to hinder the rotation of the turntable 220, and fix the position of the probe.
Wherein, in order to guarantee that connecting portion 330 can only follow carousel 220 axial motion, can not produce to rotate in order to drive carousel 220 and rotate together, prevent that locking operation from influencing the position of peeping head, be provided with the spacing groove on the casing 100, be provided with the stopper on the connecting portion 330, stopper and spacing groove mutually support and are used for preventing connecting portion 330 from rotating.
As shown in fig. 3, in order to enable the probe to automatically reset after the locking handle 310 is released, the endoscope further comprises an elastic member 340 connected with the connecting part 330, and the elastic member 340 provides an upward force to the connecting part 330; wherein can select to be connected elastic component 340 and casing 100 or with carousel 220, when locking handle 310 unclamps the back, first inclined plane 311 and second inclined plane 321 remove the auto-lock state, and locking portion can rotate and along axial motion, and elastic component 340 can be with connecting portion 330 jacking upwards for connecting portion 330 removes the butt with carousel 220, and carousel 220 can rotate, and the probe can resume the original state under the effect of snake bone structure self elasticity.
Specifically, the elastic member 340 is plural, and the plural elastic members 340 are distributed around the circumference of the turntable 220.
In order to enable smooth rotation between the connecting portion 330 and the compressing portion 320, the connecting portion 330 and the compressing portion 320 are connected by a sliding chute and slider structure, and a sliding chute in the sliding chute and slider structure extends along the axial direction of the turntable 220; the sliding groove may be disposed on the connecting portion 330 or on the compressing portion 320.
