Detailed Description
Referring to fig. 1 to 2, fig. 1 is a front view of the whole of the present utility model, and fig. 2 is a cross-sectional view of the whole of the present utility model.
The utility model relates to a dental tip torque wrench, which comprises a grab handle 101, a rotating shaft 102, a rear cover 103, a spring 104 and a chuck 105, wherein the grab handle 101 comprises a connecting shell 106, a handle 107 and a connecting part 109, the handle 107 is provided with a through hole 109, the rotating shaft 102 comprises a rotating shaft 110 and a placing seat 111, the rear cover 103 comprises a spiral block 112 and a cover plate 113, and the problem that the existing torque wrench can only be generally suitable for a tip with a flat specification is solved through the scheme.
For this embodiment, the rotating shaft 102 is connected to the grab handle 101 and is located at one side of the grab handle 101, the rear cover 103 is disposed at one side of the grab handle 101, the spring 104 is disposed between the rotating shaft 102 and the rear cover 103, the chuck 105 is fixedly connected to the rotating shaft 102 and is located at one side of the rotating shaft 102, when in use, different openings on the chuck 105 can be selected according to requirements, so that the chuck can be suitable for tips with different flat positions, after the tips are placed on the openings of the chuck 105, medical staff can hold the grab handle 101 to start to rotate, under the action of friction force, the rotating shaft 102 is driven to rotate along with the chuck, so that the effect of screwing in and unscrewing the tips is achieved.
Wherein, the connection shell 106 is connected with the rotation shaft 102, and is located at one side of the rotation shaft 102, the handle 107 is fixedly connected with the connection shell 106, and is located at one side of the connection shell 106, the rotation shaft 102 and the rear cover 103 can be placed in the connection shell 106, and when the connection shell is needed to be used, medical staff can grasp the handle 107 to drive the rotation shaft 102 in the connection shell 106 to rotate.
Secondly, the connecting portion 109 is fixedly connected with the connecting shell 106 and fixedly connected with the handle 107, so that the connecting shell 106 and the handle 107 are connected and fixed through the connecting portion 109, the strength of the grab handle 101 is enhanced, and the service life is prolonged.
