In this embodiment, the handpiece body 300 is used to form the engraving head portion of the engraving device 100, wherein the drill connecting shaft 320 of the handpiece body 300 is rotated by the engraving motor 600 in the engraving device 100. By the split design of the drill bit 310 and the drill bit connecting shaft 320, the drill bit 310 can be preferably replaced when the drill bit 310 is damaged or needs to be replaced according to production requirements. Wherein, the positioning device 350 is capable of preferably positioning the drill bit 310 and the drill bit connecting shaft 320 in the circumferential and axial directions through cooperation with the first positioning hole 314, the second positioning hole 323 and the third positioning hole 324. In addition, in order to secure the connection strength of the drill bit 310 and the drill bit connection shaft 320 in the circumferential direction, the positioning means 350 should be provided at least 2 and uniformly distributed in the circumferential direction.

As shown in fig. 29, in the present embodiment, the positioning device 350 includes a positioning pin 351 disposed in the second positioning hole 323, and a positioning portion 352 is formed by protruding the middle portion of the positioning pin 351 along the outer periphery; the inner wall of the inner end of the second positioning hole 323 is provided with a second spring limiting part protruding towards the inner periphery, a second spring 353 sleeved at the positioning pin 351 is arranged between the second spring limiting part and the positioning part 352, and the inner wall of the outer end of the second positioning hole 323 is provided with a positioning pin ring plate 354 positioned at the outer side of the positioning part 352.

In this embodiment, the positioning pin 351 can move freely in the radial direction in the second positioning hole 323, so that the drill bit 310 can be detached and assembled at the drill bit connecting shaft 320. In addition, the second spring 353 is provided such that: when the drill bit 310 is required to be arranged at the drill bit connecting shaft 320, the positioning pin 351 can be moved inwards against the elastic force of the second spring 353 until the inner end of the positioning pin 351 reaches the third positioning hole 324, and a fixing mechanism is adopted to limit the position of the positioning pin 351; when the drill bit 310 needs to be removed from the drill bit connecting shaft 320, the limitation of the fixing mechanism on the positioning pin 351 is only required to be removed, and the positioning pin 351 can be automatically ejected under the action of the elastic force of the second spring 353, so that the removal of the drill bit 310 can be better facilitated. The fixing mechanism can tightly hold the positioning pin 351 from the periphery by adopting a hoop, and the fixing mechanism can also be realized by enabling the inner end of the positioning pin 351 to be in threaded fit or clamping fit with the third positioning hole 324.

In this embodiment, a spring mounting portion 312 is disposed between the lower portion and the upper portion of the drill 310, and the lower end of the spring mounting portion 312 protrudes to the periphery to form a limiting portion 316; a sleeve 340 is sleeved outside the drill bit 310 in a vertically movable manner, and the sleeve 340 is used for being matched with the positioning pin 351; the lower part of the inner wall of the sleeve 340 is recessed to the periphery to form a spring mounting cavity, the limiting part 316 is slidably arranged in the spring mounting cavity, and a first spring 330 is arranged between the limiting part 316 and the bottom wall of the spring mounting cavity.

In the present embodiment, the sleeve 340 is selected to constitute a fixing mechanism for restricting the positioning pin 351, and the sleeve 340 can be provided outside the drill bit 310 without falling off. This makes it possible to apply a force from the drill bit 310 to the drill bit connection shaft 320 when the drill bit 310 is installed, and the positioning pins 351 are all extended outwards under the action of the second springs 353 so as not to affect the penetration of the drill bit 310, and after the drill bit 310 is inserted in place, the positioning pins 351 can be pressed to move inwards until the positioning pins are contracted in the inner area of the sleeve 340, and at this time, the sleeve 340 is displaced upwards under the action of the first springs 330, so that the inward contracted state of the positioning pins 351 can be effectively maintained, and the connection between the drill bit 310 and the drill bit connection shaft 320 can be realized more conveniently. When the drill bit 310 needs to be removed, only a force away from the drill bit connecting shaft 320 needs to be applied from the sleeve 340, at this time, the sleeve 340 overcomes the elasticity of the first spring 330 to displace downwards relative to the drill bit 310, when the sleeve 340 displaces to a range separating from the positioning pin 351 in a direction away from the drill bit connecting shaft 320, the positioning pin 351 can be automatically ejected under the elasticity of the second spring 353, and as the positioning pin 351 is ejected, the connection between the drill bit 310 and the drill bit connecting shaft 320 is also released, so that the drill bit 310 can be removed from the drill bit connecting shaft 320 more conveniently.

In this embodiment, a limiting ring 360 is disposed at the opening at the lower end of the spring mounting cavity and below the limiting portion 316. So that the sleeve 340 preferably does not fall off the drill bit 310.

In this embodiment, an inclined positioning chute 341 is disposed on the upper portion of the inner sidewall of the sleeve 340 and is matched with the positioning pin 351, the depth of the upper end of the positioning chute 341 is not less than the maximum length of the positioning pin 351 extending outwards, and the lower end of the positioning chute 341 extends to the inner sidewall of the sleeve 340.

In this embodiment, the positioning sliding groove 341 is configured such that, when the drill bit 310 is installed, after the drill bit 310 is installed in place, the positioning sliding groove 341 provides a guide for the positioning pin 351, and under the action of the first spring 330, the positioning pin 351 can automatically retract inwards due to the force of the sleeve 340, so that the installation of the drill bit 310 can be preferably realized. In addition, the number of the positioning sliding grooves 341 is the same as the number of the positioning pins 351 and is correspondingly set, when the drill bit 310 is installed, the sleeve 340 can be rotated by an angle relative to the drill bit 310, and the positions of the positioning sliding grooves 341 and the corresponding positioning pins 351 are staggered, so that the sleeve 340 cannot interfere the positioning pins 351 prematurely to further interfere with the insertion of the drill bit 310. In addition, when the drill bit 310 is removed, the positioning pins 351 gradually extend outwards due to the action of the positioning sliding grooves 341, so that impact damage to relevant components caused by the fact that the positioning sliding grooves 341 are suddenly and outwards popped up can be effectively reduced.

In this embodiment, the number of the first positioning holes 314 is at least 2 and is uniformly distributed along the circumferential direction of the first groove 315, the first positioning holes 314 are disposed between adjacent positioning strips 313, and the positioning strips 313 are at least 3. Thereby making the connection of the drill bit 310 and the drill bit connection shaft 320 more stable. Also, since the first positioning holes 314 are provided between the adjacent positioning bars 313, the position of the positioning pins 351 is located at a thicker region between the adjacent positioning grooves 321, so that the arrangement of the positioning pins 351 can be preferably facilitated.
