[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] like Figures 1 to 6 , an oral screwdriver comprises: a handle 1, a screwdriver head 2, a screw 3 and a connecting rod mechanism 4, the front end of the handle 1 is provided with a screwdriver head 2, the end of the screwdriver head 2 away from the handle 1 is provided with a screw 3, the surface of the screwdriver head 2 close to the screw 3 is installed with a connecting rod mechanism 4, and the connecting rod mechanism 4 includes a moving block 41, a clamping rod 42, a movable plate 43, a fixed seat 44 and a transmission rod 45. Moving blocks 41 are symmetrically provided on both sides of the screwdriver head 2, the surface of the moving block 41 close to the screw 3 is fixedly connected with the clamping rod 42, the surface of the screwdriver head 2 is fixedly connected with the movable plate 43, and the movable plate 43 is located on the side of the moving block 41 away from the clamping rod 42, the surface of the screwdriver head 2 is symmetrically fixedly connected with the fixed seat 44, and the fixed seat 44 is located between the moving block 41 and the movable plate 43, and the round rods on the upper surfaces of the moving block 41 and the movable plate 43 are rotatably connected with the transmission rod 45.

[0028] In this embodiment, the handheld handle 1 is held close to the screw 3, driving the screwdriver head 2 away from the end of the handle 1 close to the screw 3, and the movable plate 43 is close to the fixed seat 44. Since the round rods on the upper surfaces of the movable block 41 and the movable plate 43 are rotatably connected with the transmission rod 45, the transmission rod 45 drives the movable block 41 close to the screw 3, and the two clamping rods 42 approach each other to clamp the screw 3 firmly. The movable plate 43 is away from the fixed seat 44, driving the clamping rods 42 away from each other, making it easy to loosen the screw 3. In actual operation, the screw 3 will not easily fall into the patient's mouth.

[0029] As attached Figure 4 As shown, the link mechanism 4 further includes a first link rod 46 and a second link rod 47 , and the moving block 41 and the inner wall of the fixing seat 44 are rotatably connected with the first link rod 46 and the second link rod 47 .

[0030] In this embodiment, when the movable plate 43 moves away from the fixed seat 44, it drives the moving blocks 41 away from each other, and the first connecting rod 46 and the second connecting rod 47 rotate on the inner walls of the moving block 41 and the fixed seat 44, driving the clamping rod 42 away from each other, releasing the screw 3, and transmitting the moving block 41 and the fixed seat 44.

[0031] As attached Figure 5 As shown, a driving mechanism 5 is fixedly installed on the surface of the screwdriver head 2 for providing drive for the connecting rod mechanism 4. The driving mechanism 5 includes a circular ring seat 51 and an electric push rod 52. The surface of the screwdriver head 2 close to the handle 1 is fixedly connected to the circular ring seat 51, and the surface of the circular ring seat 51 away from the screwdriver head 2 is symmetrically fixedly connected to the electric push rod 52, and the moving end of the electric push rod 52 is fixedly connected to the surface of the movable plate 43 away from the fixed seat 44.

[0032] In this embodiment, the annular seat 51 is close to the surface of the movable plate 43 and the electric push rod 52 is extended, driving the movable plate 43 to approach the fixed seat 44. The two clamping rods 42 are close to clamp the screw 3 firmly, providing drive for the connecting rod mechanism 4. The electric push rod 52 contracts, driving the movable plate 43 away from the fixed seat 44, making it easier to loosen the screw 3.

[0033] As attached Figure 5 As shown, the driving mechanism 5 further includes a guide rod 53 , and the guide rod 53 is slidably connected to the circular hole on the surface of the movable plate 43 , and both sides of the guide rod 53 are fixedly connected to the surfaces of the fixing seat 44 and the annular seat 51 .

[0034] In this embodiment, when the movable plate 43 moves toward or away from the fixed seat 44 , the guide rod 53 slides along the circular hole on the surface of the movable plate 43 to ensure stable movement of the movable plate 43 .

[0035] As attached Figure 6 As shown, a rotating mechanism 6 is installed inside the handle 1 for driving the screwdriver head 2 to rotate. The rotating mechanism 6 includes a rotating mounting groove 61, a driving motor 62 and a bearing 63. A rotating mounting groove 61 is opened inside the handle 1. The driving motor 62 is fixedly installed on the inner wall of the rotating mounting groove 61, and the output shaft of the driving motor 62 is fixedly connected to the side of the screwdriver head 2 close to the handle 1. The output shaft surface of the driving motor 62 is fixedly connected to the bearing 63, and the outer ring surface of the bearing 63 is fixedly connected to the inner wall of the rotating mounting groove 61.

[0036] In this embodiment, the drive motor 62 on the inner wall of the rotating mounting groove 61 is started, and the output shaft of the drive motor 62 rotates, driving the screwdriver head 2 to rotate. The machine replaces manual labor, driving the screwdriver head 2 to rotate. When the output shaft of the drive motor 62 rotates, the bearing 63 ensures that the output shaft of the drive motor 62 rotates stably.

[0037] As attached Figure 1 and Figure 2 As shown, three control buttons 7 are installed on the upper surface of the handle 1.

[0038] In this embodiment, by pressing the control button 7 , the drive motor 62 can be controlled to start, driving the screwdriver head 2 to rotate, and the electric push rod 52 can also be controlled to extend and retract, providing drive for the connecting rod mechanism 4 .

[0039] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
