further, a locking plate 40 groove for accommodating the locking plate 40 is formed on the laryngoscope body 10, the locking plate 40 is disposed in the locking plate 40 groove, a through hole is formed through the middle part of the locking plate 40 groove, a pivot shaft 42 is connected with the through hole, and the locking plate 40 rotates around the pivot shaft 42.

Furthermore, a leaning step is formed at the first end of the slot of the locking plate 40, and a positioning step 43 is formed at the second end of the locking plate 40 in an extending manner and is leaned against the leaning step to limit the locking plate from further penetrating into the slot 111; under the normal state, the locking plate 40 is flatly arranged on the outer side wall of the laryngoscope main body 10 and does not exceed the upper surface of the laryngoscope main body 10, and the integral flatness of the product is realized.

When the staff is operating the laryngoscope, the condition that mistake touching locking plate 40 may appear to make tongue depressor piece 20 form the unblock dismantlement by accident, cause certain inconvenience to operation process, in order to solve this technical problem, the embodiment provides following technical scheme:

specifically, the laryngoscope further comprises a knob unlocking component 30 coaxially arranged on the laryngoscope main body 10, wherein the knob unlocking component 30 covers the second end part of the locking plate 40 and can rotate along the circumferential direction of the laryngoscope main body 10;

further, a pressing block 311 is arranged on the inner side wall of the knob unlocking component 30;

wherein, the knob unlocking assembly 30 rotates to drive the pressing block 311 to press the second end of the locking plate 40, and to rotate the locking plate 40 around the pivot joint;

in the above-described aspect, in the normal state, the pressing piece 311 does not abut against the second end portion of the lock piece 40; when the operator rotates the knob unlocking assembly 30, the pressing block 311 approaches the second end of the locking plate 40 until abutting against the second end of the locking plate 40, and the pressing block 311 presses the second end of the locking plate 40 to achieve a state similar to pressing, so that the above-mentioned effect of driving the locking plate 40 to rotate is achieved, the locking hook 41 is separated from the locking groove 211, and the tongue depressor 20 is unlocked and detached; by adopting the mode, the second end part of the locking plate 40 is effectively protected, the separation of the tongue depressor 20 caused by the fact that a worker mistakenly touches the second end part of the locking plate 40 in the operation process is prevented, and the subsequent practical use is facilitated; a knob type unlocking mode is adopted, the structure is novel and ingenious, and the use is convenient and quick;

further, the pressing block 311 is formed with a guiding slope along both sides of the rotation direction thereof, and when the knob unlocking assembly 30 is rotated, the guiding slope plays a guiding role, guides the top of the slope of the pressing block 311 to the locking plate 40, and abuts against the second end of the locking plate 40 to realize unlocking.

Specifically, the knob unlocking assembly 30 comprises a knob main body 31 in a cylindrical ring shape, and a second elastic assembly 32 arranged between the knob main body 31 and the laryngoscope main body 10;

further, the pressing block 311 is disposed on the inner sidewall of the knob body 31;

further, the second elastic component 32 is sleeved on the laryngoscope body 10 and limits the knob body 31 to rotate around the circumference of the laryngoscope body 10;

in the above scheme, when the operator rotates the knob body 31, the operator needs to resist the elastic force of the second elastic component 32, when the operator rotates, the second elastic component 32 stores elastic potential energy, and after the operator unlocks the knob body 31, the second elastic component 32 releases the elastic potential energy to reset the knob; by adopting the mode, the automatic reset of the knob main body 31 can be realized, so that the use of the laryngoscope is more flexible and convenient; meanwhile, the second elastic component 32 limits the rotation of the knob body 31 to a certain extent, so that an operator is not easy to stir the knob body 31 in the operation process, the operation process is more stable, and the knob body is not easy to be influenced.

Specifically, the second elastic component 32 is annular, and two ends of the second elastic component are respectively turned towards the axis center and turned away from the axis center;

wherein, the inner turning end 321 is fixed on the laryngoscope body 10, and the outer turning end 322 is fixed on the knob body 31;

in the above scheme, the inner turning end 321 of the second elastic component 32 is fixed on the laryngoscope body 10, the outer turning end 322 is fixed on the knob body 31, and when the two are rotated relatively, the second elastic component 32 can store elastic potential energy;

further, an embedded groove for inserting the second elastic component 32 is formed on the laryngoscope body 10, and a mounting hole 312 is formed on the knob body 31;

in the above scheme, the staff can insert the outer turning end 322 of second elastic component 32 on the mounting hole 312 of knob main part 31 earlier, accomplish the preliminary fixed of second elastic component 32 and knob main part 31, aim at the embedded groove of laryngoscope main part 10 with the inner turning end 321 of second elastic component 32 afterwards, locate laryngoscope main part 10 with knob main part 31 cover down along the extending direction of embedded groove, so completed three's installation promptly, the installation is simple and convenient, can promote production efficiency.

Further, an anti-slip pattern is formed on the outer side wall of the knob body 31; the anti-slip lines on the knob body 31 can increase the relative friction between the knob body 31 and the hand of the operator, reduce the risk of slipping, and make the knob body 31 easier to control.
