[0045] Example 1

[0046] like Figures 1 to 6As shown, the utility model provides a dental handpiece presser, which comprises: a fixing frame 1, which is provided with a receiving space 101 for locating the position of a dental handpiece 9; a sleeve 2, which is arranged on one side of the fixing frame 1; the sleeve 2 is provided with a through slot 201 connected to the receiving space 101; an operating assembly, which comprises a handle 4, a rod body 6 and a pressing member 5; the handle 4 is arranged outside the sleeve 2, the rod body 6 is located in the through slot 201, the pressing member 5 is located in the receiving space 101, and the handle 4 is connected to the pressing member 5 through the rod body 6; the rod body 6 is threadedly connected to the inner circumference of the sleeve 2, so that the pressing member 5 can perform telescopic movement in the receiving space 101 along the length direction of the rod body 6.

[0047] The present application positions the dental handpiece 9 in the accommodating space 101 and arranges the button portion 903 of the dental handpiece 9 corresponding to the pressing member 5. The doctor drives the rod body 6 to rotate through the handle 4 so that the pressing member 5 performs telescopic movement along the length direction of the rod body 6, and presses the button portion 903 of the dental handpiece 9 to simulate a human hand pressing the button portion 903, thereby achieving replacement of the needle 901. The doctor is no longer required to press the button portion 903 during the operation, thereby avoiding long-term pressing operation to cause tenosynovitis in the doctor and protecting the doctor's health.

[0048] Specifically, the doctor drives the rod body 6 to rotate forward by rotating the handle 4 in the forward direction. Due to the threaded fit, the rod body 6 will extend relative to the sleeve 2 in the direction of the accommodating space 101, so that the pressing member 5 moves toward the button portion 903 of the dental mobile phone 9 and presses the button portion 903 to open the clamping member, thereby removing the old needle 901 and replacing it with a new needle 901; the doctor then drives the rod body 6 to rotate reversely by rotating the handle 4 in the reverse direction. Due to the threaded fit, the rod body 6 will retract relative to the sleeve 2 in the direction away from the accommodating space 101, so that the pressing member 5 moves away from the button portion 903 of the dental mobile phone 9 and no longer presses the pressing portion, so that the clamping member clamps the new needle 901 to assist the doctor in replacing the needle 901.

[0049] Since the rod body 6 needs to be rotated to realize the telescopic movement of the rod body 6, in order to prevent the pressing piece 5 from slipping due to rotation, or scratching the button part 903 of the dental mobile phone 9 due to rotation, in the present embodiment, the rod body 6 has a first end and a second end, and the first end is rotatably connected to the pressing piece 5 so that the pressing piece 5 can rotate without rotating along with the rotation of the rod body 6, thereby preventing the pressing piece 5 from slipping or scratching the button part 903 of the dental mobile phone 9 due to rotation. After the pressing piece abuts against the button part, the pressing piece can be kept from rotating and only extend out, thereby ensuring that the button part can be pressed; the second end is connected to the handle 4 so that the handle 4 drives the rod body 6 to rotate.

[0050] Furthermore, the first end is rotatably connected to the pressing member 5 via a bearing structure, and the bearing structure enables the pressing member 5 to perform telescopic movement along with the telescopic movement of the rod body 6 without being affected by the rotational movement of the rod body 6. Specifically, the bearing structure includes a bearing center axis 7 and a plurality of bearing beads 8 distributed around the bearing center axis 7, and the bearing center axis 7 is connected and fixed to the first end, and limits the position of the pressing member 5, so that the pressing member 5 can rotate relative to the rod body 6 under the sliding action of the bearing beads 8 without being affected by the rotational movement of the rod body 6.

[0051] In this embodiment, the handle 4 is sleeved outside the sleeve 2, and the handle 4 is provided with a receiving groove 401; the handle 4 has a receiving position relative to the sleeve 2; when the handle 4 is in the receiving position, the sleeve 2 is received in the receiving groove 401 of the handle 4. Specifically, when the needle 901 does not need to be replaced, in order to reduce the space occupied by the dental handpiece presser of the present application, the doctor drives the rod body 6 to rotate forward by rotating the handle 4 in the forward direction. Due to the threaded fit, the handle 4 will move forward relative to the sleeve 2 toward the direction of the fixing frame 1, so that the sleeve 2 is received in the receiving groove 401 of the handle 4, shortening the length of the present application and facilitating storage.

[0052] Furthermore, the handle 4 is further provided with a mounting groove 402 communicating with the storage groove 401, and the mounting groove 402 is provided at one end of the storage groove 401 away from the fixing frame 1; the second end of the rod body 6 is provided with a mounting protrusion, and the mounting protrusion is installed in the mounting groove 402. Specifically, the mounting protrusion can be installed in the mounting groove 402 by interference fit to achieve the connection and fixation between the handle 4 and the rod body 6, and can also be achieved by other methods, which is not limited by the present application.

[0053] In this embodiment, the inner circumference of the sleeve 2 is provided with an internal thread; the outer circumference of the rod body 6 is provided with an external thread, and the external thread cooperates with the internal thread. Specifically, the doctor drives the rod body 6 to rotate forward by rotating the handle 4 forward. During the forward rotation of the rod body 6, the external thread of the rod body 6 cooperates with the internal thread of the sleeve 2. Since the sleeve 2 is relatively stationary, the rod body 6 will extend relative to the sleeve 2 in the direction of the accommodating space 101, so that the pressing member 5 moves toward the button portion 903 of the dental handpiece 9.

[0054] In addition, the internal thread and the external thread of the present application are designed between the sleeve 2 and the rod body 6 and are not exposed to the outside, which is confidential and protective, ensuring that the thread of the present application is not damaged and increasing the service life.

[0055] In one embodiment, the outer circumference of the handle 4 is provided with anti-slip grooves to increase the friction when the doctor rotates the handle 4.

[0056] Regarding the connection and fixation between the sleeve 2 and the fixing frame 1, in the present embodiment, one end of the sleeve 2 is provided with a limiting portion extending toward the circumferential side, the limiting portion is arranged in the accommodating space 101 and abuts against the inner side surface of the fixing frame 1; the dental handpiece presser also includes a fixing cap 3, the fixing cap 3 is sleeved outside the sleeve 2 and abuts against the outer side surface of the fixing frame 1. Specifically, in the design process of the present application, the sleeve 2, the fixing frame 1 and the fixing sleeve are designed with separate molds to facilitate production and manufacturing, wherein the limiting portion of the sleeve 2 abuts against the inner side surface of the fixing frame 1, and then the fixing cap 3 and the sleeve 2 are interference-fitted to achieve the compression and fixation of the fixing cap 3 with the fixing frame 1 and the sleeve 2, which facilitates installation and simplifies installation operations.

[0057] In this embodiment, the fixing frame 1 is further provided with a clearance groove 102 for accommodating the needle 901 of the dental handpiece 9, and the clearance groove 102 is connected with the accommodating space 101; the clearance groove 102 is arranged on the other side of the fixing frame 1, and the clearance groove 102 is arranged corresponding to the sleeve 2. In the process of positioning the dental handpiece 9 in the accommodating space 101, the needle 901 of the dental handpiece 9 will be placed corresponding to the clearance groove 102, and the position of the fixing frame 1 located on the side of the clearance groove 102 is used to fix the handpiece bearing 902 at the front end of the dental handpiece 9, so as to prevent the handpiece bearing 902 from being pushed forward and causing damage during the process of replacing the needle 901.

[0058] Example 2

[0059] This embodiment is basically the same as the embodiment 1, and the difference is that the handle 4 of this embodiment is threadedly connected to the outer peripheral side of the sleeve 2, so that the pressure piece 5 can perform telescopic movement in the accommodating space 101 along the length direction of the rod body 6. Specifically, the outer peripheral side of the sleeve 2 is provided with an external thread; the inner peripheral side of the receiving groove 401 is provided with an internal thread, and the internal thread cooperates with the external thread. The doctor drives the rod body 6 to rotate forward by rotating the handle 4 in the forward direction. During the forward rotation of the rod body 6, under the cooperation of the external thread of the sleeve 2 and the internal thread of the receiving groove 401, since the sleeve 2 is relatively stationary, the rod body 6 will extend relative to the sleeve 2 in the direction of the accommodating space 101, causing the pressure piece 5 to move toward the button portion 903 of the dental handpiece 9.

[0060] In addition, the handle 4 can effectively protect the external thread of the sleeve 2 by accommodating the sleeve 2, thereby preventing foreign matter from damaging the external thread on the outer peripheral side of the sleeve 2.

[0061] Example 3

[0062] like Figure 7 As shown, this embodiment is basically the same as the embodiment 1, and the difference is that the handle 4 of this embodiment is arranged at the second end of the rod body 6, and the handle 4 is not sleeved outside the sleeve 2, and the inner circumference of the sleeve 2 is provided with an internal thread; the outer circumference of the rod body 6 is provided with an external thread, and the external thread cooperates with the internal thread. The doctor drives the rod body 6 to rotate forward by rotating the handle 4 in the forward direction. During the forward rotation of the rod body 6, the external thread of the rod body 6 cooperates with the internal thread of the sleeve 2. Since the sleeve 2 is relatively stationary, the rod body 6 will extend relative to the sleeve 2 in the direction of the accommodating space 101, so that the pressing member 5 moves toward the button portion 903 of the dental handpiece 9.

[0063] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
