Summary of the invention
This utility model is to inscribe for the technology that solves above-mentioned common goose saw saw blade mounting structure existence, and proposes the saw blade mounting structure of a kind of bone surgery with goose saw.
This utility model is taked following technical scheme for the technical problem that solves above-mentioned common goose saw saw blade mounting structure existence: the saw blade mounting structure of this goose saw comprises oscillating deck and goose saw saw blade, feature is, oscillating deck is connected with the saw blade gripper shoe that is positioned at the head outside, described saw blade gripper shoe is provided with the hugging of corresponding saw blade installation portion, the side at described hugging two ends along be provided with goose saw saw blade surface engagement before, rear fender, the installation portion of described goose saw saw blade is provided with elastic collet, its perk end engages with front pressuring plate medial extremity edge, and the operate portions of described goose saw saw blade is provided with the spacing shoulder that engages with front pressuring plate outboard end edge.
This utility model can also be taked following technical measures:
The saw blade gripper shoe that described oscillating deck is in transmission connection is the other end that the saw blade gripper shoe is fixedly connected on the corresponding shift fork end of oscillating deck.
The saw blade gripper shoe that described oscillating deck is in transmission connection is that the saw blade gripper shoe is fixedly connected on reciprocal rotating shaft.
The hugging of described saw blade gripper shoe, the forward and backward pressing plate at its two ends are respectively equipped with radial technology fluting.
The beneficial effects of the utility model and advantage are: this bone surgery is in transmission connection in the oscillating deck or the back and forth rotating shaft of former goose saw with the saw blade gripper shoe of the saw blade mounting structure of goose saw, this saw blade gripper shoe is provided with the embedding hole slot of the saw blade installation portion that the forward and backward pressing plate by hugging and hugging two ends constitutes, and the elastic collet of goose saw saw blade installation portion and spacing shoulder constitute the location and the retaining mechanism of saw blade.This saw blade mounting structure makes not only that the goose saw saw blade can be reliable and stable is fixed in the saw blade gripper shoe, and the embedding of goose saw saw blade and taking-up need not tool using and a step finishes, once pushing away, press elastic collet when taking out the goose saw saw blade and can take advantage of a situation and extract the goose saw saw blade when embedding the goose saw saw blade.This saw blade mounting structure makes saw blade installation portion surface not have any projection that stops the operating doctor sight line.The utlity model has outstanding advantage simple in structure, easy to use and that be difficult for breaking down.
