As shown in Figs. 1 and 2, a disposable electric bone rasp comprises a connecting member 1, a magnetic induction member, a transmission structure 2, a blade tube and a rasp head 5 which are sequentially arranged from left to right. The connecting piece 1 is used for being connected with the motor drive of the planing handle to provide power for the utility model; the magnetic induction piece is used for the planing handle to distinguish the product specification of the utility model, and the rotating speed is changed according to the specification; the transmission structure 2 is used for realizing the reciprocating motion of the file head 5 by the fitting and extrusion of the inner contour; the cutter tube is used for connecting the transmission structure 2 and the file head 5; the rasp head 5 is used to grind the surface of bone tissue.
Referring to fig. 3, the transmission structure includes a housing 23, an upper transmission shaft 21 and a lower transmission shaft 22, the housing 23 is a hollow housing, and is sleeved on the peripheries of the upper transmission shaft 21 and the lower transmission shaft 22, one end of the housing is fixed to a buckle interface extending from the bottom of the lower transmission shaft 22 by a buckle, the other end of the housing is provided with an end cover on the periphery of the connecting piece 1, the end cover is provided with a buckle interface matched with the housing 23 and fixed to the buckle interface by a buckle; the sword pipe includes interior sword pipe 4 and outer sword pipe 3, and 1 one end of connecting piece is connected with the planing handle, and the other end cup joints in last transmission shaft 21 periphery to pass through the profile of tooth with last transmission shaft 21 and be connected, the concrete setting that the profile of tooth is linked is: tooth grooves are arranged on the periphery of the joint of the upper transmission shaft 21 and the connecting piece 1 at equal intervals, correspondingly, tooth keys are arranged on the inner periphery of the connecting piece 1 and the tooth grooves in a matching mode, and the tooth grooves and the tooth keys form meshed tooth-shaped links, so that when the connecting piece rotates, the upper transmission shaft 21 can be driven to rotate due to the meshing of the tooth grooves and the tooth keys. The upper transmission shaft 21 is axially fixed with the inner knife pipe 4, and the position of the upper transmission shaft is arranged at the periphery close to the left end part, so that the upper transmission shaft 21 can drive the inner knife pipe 4 to axially move and can also rotate at the periphery of the inner knife pipe 4.
Referring to fig. 4, the inner cutter tube 4 is provided with a waist groove 9, the outer cutter tube 3 and the lower transmission shaft 22 at the same position are provided with through holes, the through holes are provided with pins 8, the pins 8 penetrate through the lower transmission shaft 22 and the outer cutter tube 3 to fix the lower transmission shaft and the outer cutter tube 3 with each other, and the pins 8 penetrate through the inner cutter tube 4 through the waist groove 9. This arrangement makes the outer cutter tube 3 and the lower drive shaft 22 immovable and the inner cutter tube 4 can reciprocate only left and right with respect to the outer cutter tube 3 and the lower drive shaft 22.
The power source of the inner cutter tube 4 is the transmission structure 2, the upper transmission shaft 21 and the lower transmission shaft 22 of the transmission structure 2 are provided with two contour surfaces for matching, the contour surface of the lower transmission shaft 22 is fixed, the upper transmission shaft 21 is driven by the connecting piece 1 to rotate on the periphery of the inner cutter tube 4, due to the special upper and lower fluctuating curved surfaces of the contour surfaces, when the contour surface of the upper transmission shaft 21 is attached and extruded with the contour surface of the lower transmission shaft 22, the lower transmission shaft 22 is fixed and immovable, the upper transmission shaft 21 performs left and right axial reciprocating motion relative to the lower transmission shaft 22, and because the upper transmission shaft 21 is axially fixed with the inner cutter tube 4, the upper transmission shaft 21 drives the inner cutter tube 4 to perform reciprocating motion relative to the lower transmission shaft 22. Since the lower driving shaft 22 is fixed to the outer tube 3 by the pin 8, the inner tube 4 reciprocates relative to the outer tube 3, and the left end of the inner tube 4 extends out of the outer tube 3 and is connected to the rasp head 5, the rasp head 5 reciprocates in the axial direction when the connecting member 1 rotates after the connecting member 1 is connected to the planing handle, thereby realizing an electric sanding function, and the rasp head 5 has a saw-tooth structure and thus enhancing the efficiency of sanding.
It is worth noting that at the tooth-shaped connection position of the connecting piece 1 and the upper transmission shaft 21, a spring 7 is arranged inside the connecting piece 1, one end of the spring 7 abuts against the inner end face of the connecting piece 1, and the other section of the spring 7 is pressed against the end part of the upper transmission shaft 21, so that the contour surfaces of the upper transmission shaft 21 and the lower transmission shaft 22 are always attached and extruded.
Furthermore, two steel balls 24 are arranged between the contour surfaces of the upper transmission shaft 21 and the lower transmission shaft 22, and correspondingly, two steel ball holes for placing the steel balls 24 are arranged on the contour surface of the lower transmission shaft 22, and the depth of each steel ball hole is slightly larger than the radius of each steel ball 24, so that the position of each steel ball 24 can be fixed, and the function of each steel ball 24 is not influenced. The arrangement of the steel balls 24 enables the profile surfaces of the upper transmission shaft 21 and the lower transmission shaft 22 not to be in direct contact, and avoids the direct extrusion of the profile surfaces of the upper transmission shaft 21 and the lower transmission shaft 22 when the upper transmission shaft 21 rotates, and because the upper transmission shaft 21 and the lower transmission shaft 22 are made of plastic materials, when the upper transmission shaft 21 and the lower transmission shaft 22 rub at high speed, the temperature can rise rapidly, and when the temperature is too high, the upper transmission shaft 21 and the lower transmission shaft 22 can melt.
Magnetic induction spare sets up inside transmission structure 2's casing 23 to the periphery of last transmission shaft 21 is located to the cover, is provided with a plurality of magnet mounting grooves, works as the utility model discloses when installing on the planing system handle, magnet 6's quantity can be sensed to the handle, thereby discernment installation the utility model discloses the specification of product, different the utility model discloses a required rotational speed of specification of product is different, say that a magnet 6 represents a shelves rotational speed, and two magnet 6 represent two and keep off the rotational speed, so on. Therefore, when the utility model discloses when installing on the handle, 6 quantity of magnet of handle response magnetic induction portion, the automatic adjustment rotational speed, the utility model discloses be provided with 4 magnet 6, be greater than 4 magnet 6 certainly and also not influence the utility model discloses an excellent in use effect. Of course, the utility model discloses a magnetic induction function is realized through the position and the quantity of discernment magnet 6, and this scheme also can be replaced to realize through discernment magnetism intensity of induction.
Referring to fig. 5, the utility model discloses an innovation point still lies in, and we set up interior tool tube 4 to hollow tubular metal resonator, and rasper head 5 is provided with attracts hole 51, attracts hole 51 and hollow interior tool tube 4 to communicate each other, works as the utility model discloses can be connected to the vacuum suction pump when the product is used, vacuum suction pump intercommunication hollow interior tool tube 4 can polish on one side and attract the human body with the bone bits outside.
It should be noted that the product of the present invention is a disposable consumable material provided aseptically, which can reduce the risk of cross-infection.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention in any way.
