Regarding the implementation state of the present creation, first, as shown in FIG. 5, the present invention can be configured such that the combination portion 201 of the grip 20 is just engaged by pivoting the handle 20 90 degrees about the connecting rod 51 as a central axis. When the operator locks a to-be-locked item with the ratchet wrench 1 on the side of the card abutting portion 13 of the body 10, the handle 20 can be continuously and stably engaged at the assembly portion of the body 10.

Alternatively, as shown in FIG. 6 , the present invention uses the grip 20 to be pivotally connected to the body 10 , and can be applied to an item limited by the screw depth, and the artificial implant is taken as an example. Before implanting the artificial tooth, the dentist will implant an implant in the patient's lower jaw bone, and then an artificial tooth will be fixed in the center of the implant, using the adjustment column 53 of the creation. The relative screwing distance from the connecting rod 51 can adjust the pushing strength of the compression spring 52 to the direction of the handle 20 toward the body 10, thereby determining the maximum torque limit that can be used during the pivoting process. The screw depth of the body is positively correlated with the required torque. As the depth of the implant is gradually increased, the torque applied by the handle 20 to the body 10 needs to be continuously increased to smoothly perform the screw lock. .

It can be known from the above that if the dentist sets a torque value for the creation in advance, the implant can only be smoothly screwed to a certain depth, and thereafter, due to the pushing strength of the compression spring 52 to the grip 20 It is not enough to load the required torque of the screw-locking implant. If the screw lock strength is further enhanced by hand, the handle 20 will pivot with the fixing member 54 as a central axis, so that the ratchet wrench 1 directly forms a bent state, thereby Inform the dentist that the current strength of the screw-locked implant has reached the torque setting and is not suitable for continuing to screw deep into the body.

In summary, this creation can assist the dentist in burying the artificial ossicle lock in front of the patient's lower jaw bone, and first determine the maximum size of the force that can be used when the implant is implanted. In the process of locking, the force track is improperly controlled, and the workpiece bone directly passes through the patient's lower jaw bone. In addition, in order to reduce the screwing of the adjusting column 53 and the connecting rod 51, the outer surface of the adjusting column 53 and the handle are The friction coefficient of the inner peripheral wall of 20 is used to improve the smoothness of adjusting the torque. In addition, when the present invention is applied to the screw-locking implant, in order to ensure medical hygiene and cleaning, for example, regular high-temperature disinfection action, the adjustment column 53 The pushing portion 531 can be made of a Teflon material having high temperature resistance, wear resistance, and high surface smoothness.

In summary, the creation quick-release ratchet wrench not only provides the function of quick disassembly, but also determines whether to adjust the torque when using, to help determine whether the depth of the item being screwed is appropriate.
