Preferably, the operating portion of described drill bit assembling device is arranged to be driven by standard wrench.
Preferably, the outer peripheral face of the end of described clamping section is provided with the outer circumference surface coordinated with the inwall of conical bore.
Preferably, described drill bit be retracted after clamping section clamping.
Preferably, the other end of described drill bit assembling device is formed with the chip portion for boring counterbore.
Preferably, the other end of described tool bit adapter can accept screwdriver bit.
Therefore, the application provides a kind of drill bit assembling device for user, and what drill bit can be made to be simply and reliably is fixed on tool bit adapter.

Detailed description of the invention
As shown in Figure 1-2, for the application applies to the drill bit assembling device 2 of tool bit adapter 3, tool bit adapter 3 may be used for adaptive drill bit 1 and screwdriver bit 4.Wherein, drill bit 1 is held in tool bit adapter 3 by drill bit assembling device 2, and screwdriver bit 4 is adapted in tool bit adapter 3 by the hexahedron grip shank of standard.Like this, electric tool can drive drill bit 1 or screwdriver bit 4 to rotate by clamping device head adapter 3, and carries out work.
Tool bit adapter 3 comprises the grip shank 31 clamped for electric tool (not shown).As shown in Figure 3-4, tool bit adapter 3 one end cave inward and be extended with screwdriver bit 4 hexahedron grip shank adaptation in hexagonal hole 35.The other end of tool bit adapter 3 is by drill bit assembling device 2 clamping drilling bit 1, cave inward at the other end of tool bit adapter 3 and be formed with internal thread hole 34 and conical bore 33, internal thread hole 34 to extend internally formation from the end face of tool bit adapter 3, conical bore 33 internal thread hole 34 that continues continues the formation that extends internally, and wherein conical bore 34 reduces gradually from the direction extended internally of tool bit adapter 3.As shown in Figure 2, drill bit assembling device 2 is provided with the accepting hole (non-label) that runs through its longitudinal direction, and it comprises chip portion 21, operating portion 22, external thread part 23 and clamping section 25 successively from a left side from the right side, wherein, as shown in Figure 3, on the longitudinal direction of clamping section 25, gap-forming has some slits 26, by this structure, the end of clamping section 25 is retracted by slit 26, and the outer peripheral face of the end of clamping section 25 is formed with taper seat 27, this taper seat 27 shrinks gradually to the end of clamping section 25.
During assembling, the grip shank 11 of drill bit 1 first by the chip portion 21 of drill bit assembling device 2 through drill bit assembling device 2, through its accepting hole, then the internal thread hole 34 of insertion tool head adapter 3 and conical bore 33, until conflict with the bottom of conical bore 33.Then, again internal thread hole 34 and conical bore 33 are inserted in the clamping section 25 of drill bit assembling device 2, until the external screw thread of the external thread part 23 of drill bit assembling device 2 contacts with the internal thread of internal thread hole 34, again by operating portion 22 rotary drill bit assembling device 2, the internal thread of the external screw thread of external thread part 23 and internal thread hole 34 is intermeshed.In the process that external screw thread and internal thread engage gradually, the clamping section 25 of drill bit assembling device 2 advances gradually in conical bore 33, and due to the conical structure of conical bore 33, in the progradation of clamping section 25, clamping section 25 is progressively shrunk by slit 27, and the grip shank 11 of drill bit 1 clamped, until after enough firm, stop operating drill bit assembling device 2.Coordinated by this, drill bit 1 is assemblied in tool bit adapter 3 by stable, and drives it to rotate by corresponding electric tool.
The operating portion 22 of drill bit assembling device 2 can be arranged to the structure that standard wrench can be made to operate, and makes driving simpler and easy.The taper seat 27 of clamping section 25 coordinates with conical bore 33, and both contact surfaces are increased, and more easily makes clamping section 25 be clamped.Separately, chip portion 21 can make this drill bit 1 can bore counterbore when boring pre-manufactured hole, and this structure can be matched according to the actual requirements.
Be described about multiple embodiment of the present utility model above, but the embodiment that the utility model describes above being not intended to be limited to and accompanying drawing is illustrated.The feature described about an embodiment is equally applicable to other embodiment of the present utility model, and the feature of different embodiment can be combined with each other and form new embodiment.When not departing from the essence and scope that are limited by claim below, those skilled in the art can carry out various amendment and variation to above-described embodiment.
