Abstract
The invention discloses an orthopedics department medical appliance, in particular to a ratchet handle. The ratchet handle comprises a silica gel handle and an aluminum handle covered by the silica gel handle. A base is placed on the aluminum handle, and is connected with the aluminum handle through a fixing pin; a separating sleeve is placed on the base; the aluminum handle is connected with a positioning cover through the base; the positioning cover is connected with the base through snap springs; pawls are placed on the positioning cover, and are connected with the positioning cover through a pin; a spring and torsion springs are respectively placed on the pawls; a ratchet shaft is further placed at one end of the aluminum handle, and is connected with the aluminum handle through a bearing; a sliding device is a sliding sleeve placed on the ratchet shaft; the sliding sleeve is connected with the ratchet shaft through a limiting pin; compression springs are placed on the sliding sleeve; and a steel ball is further placed on the ratchet shaft. Due to the special design of the positioning cover and the special design of the sliding sleeve, the ratchet handle achieves a fast reloading function and a fast reversing function, and brings great convenience for actual operations.
Description
Technical field
The present invention relates to the orthopedic medical device technical field of tools, relate in particular to a kind of ratchet handle.
