Further, the making material of fixture is elastomeric material；
Further, drill bit rod member can connect from different drill bits.
The beneficial effects of the utility model are: simple in construction of the present utility model, by pressing and release button, control folder
Tool clamping with open, in order to change different drill bits or the drill bit having worn out, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, but does not constitute this
The concrete restriction of utility model.
Refering to shown in Fig. 1, the drilling tool of a kind of easily more bit change, including button 1, turbine 2, turbine wheel shaft 3, hold assembly 4, brill
Head rod part 5 and shell 6, turbine 2 is connected with turbine wheel shaft 3, and turbine 2 and turbine wheel shaft 3 are connecting shaft turbine, and turbine 2 is fixed on turbine wheel shaft
On 3, the two ends up and down of turbine wheel shaft 3 are arranged with clutch shaft bearing 9 and the second bearing 10, clutch shaft bearing 9 and second bearing 10 of symmetry
Internal diameter suitable with the external diameter of turbine wheel shaft 3.
Hold assembly 4 includes the side of clamping bar 41, fixture 42 and elastic plate 43, the upper side of clamping bar 41 and elastic plate 43
Fixing connection, the lower end of clamping bar 41 is fixing with the upper end of fixture 42 to be connected, and fixture 42 is taper bluff piece 421 structure symmetrical by two
Becoming, the lower end of taper bluff piece 421 is taper claw-like clamping part, and taper bluff piece 421 is arranged on the through hole in turbine wheel shaft 3
The internal face laminating of place, the outside wall surface of taper bluff piece 421 and turbine wheel shaft 3, the internal face of taper bluff piece 421 and drill bit rod member 5
Outside wall surface is fitted, and taper bluff piece 421 is slidably matched with through hole, and two symmetrical taper bluff pieces 421 can clamp drill bit rod member 5.
In order to increase the frictional force of clamping, the outer surface of drill bit rod member 5 is provided with concavo-convex anti-slip veins, and the material making fixture 42 can be
Elastomeric material.Being provided with the shell fragment 8 suitable with taper claw-like clamping part on shell 6, shell fragment 8 is arranged on taper claw-like clamping part
Lower end, shell fragment 8 is used for when taper bluff piece 421 moves down, separately taper bluff piece 421 and drill bit rod member 5.Elastic plate 43 and turbine
It is provided with spring 7 between axle 3, utilizes the flexible reseting performance of spring 7, control the motion of elastic plate 43.
The process of more bit change is: button press 1, and button 1 moves downward drive clamping bar 41 and fixture 42 moves down, due to outward
The shell fragment 8 arranged on shell 6 is positioned at taper bluff piece 421 lower end, in taper bluff piece 421 folding process, and the taper surface of taper bluff piece 421
The taper surface of laminating shell fragment 8 epimere, continues in folding process, and the epimere bending part of shell fragment 8 is become by the pressure of taper bluff piece 421
Directly, straighten part and taper bluff piece 421 is applied extrapolability, between occurring between internal face and the drill bit rod member 5 of taper bluff piece 421
Gap, fixture 42 is in relaxed state, now, the drill bit shaft 5 of abrasion is taken off, changes new drill bit rod member, is loading onto new brill
After head rod part, release button, spring 7 replys initial condition, promotes elastic plate 43 to move upward, and elastic plate 43 drives clamping bar 41
Moving upward with fixture 42, fixture 42 is not by the thrust that shell fragment 8 is outside, and therefore, fixture 42 is in through-holes to contract, tightly
Clamp drilling tool.
The above is preferred implementation of the present utility model, it is impossible to limit the right model of this utility model with this
Enclose, it is noted that for those skilled in the art, the technical solution of the utility model is modified or
Person's equivalent, without departure from protection domain of the present utility model.
