Abstract
The utility model relates to an electric drill drill bit clamping device, including last grip block, lower grip block and sleeve, go up the grip block and down the grip block have an attached column body of rectangle breach for the centre of a circle department of longitudinal symmetry, the cylinder that a centre of a circle department has the rectangle breach is constituteed to two grip blocks, upward the grip block and the lower grip block outside have the screw thread that links together, the barrel of sleeve for having the bottom surface, the round hole that a confession drill bit passed has on the bottom surface, sleeve inside has the internal thread. The utility model has the advantages of: make the rectangle with drill bit one end, drill bit centre gripping piece center department have with drill bit complex rectangle breach, the drill bit is inseparabler with the grip block cooperation, and adopts sleeve locking, and is simply convenient.
Description
Technical field
The utility model relates to a kind of field of power tools, particularly a kind of drill bit clamping device.
Background technology
It is cumbersome that existing drill bit installs operation, needs to use special erecting tools, and electric drill is circular cross-section, is easy to cause skidding or fatigue damage etc. when high-speed rotation.
Utility model content
The technical problems to be solved in the utility model is to provide one and not easily skids, drill bit clamping device easy for installation.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of drill bit clamping device, its innovative point is: comprise grip block, lower grip block and sleeve, described upper grip block and lower grip block are half cylinder that laterally zygomorphic circle centre position has rectangular indentation, two grip blocks form the cylinder that a circle centre position has rectangular indentation, have the screw thread linked together outside described upper grip block and lower grip block; Described sleeve is the cylindrical shell with bottom surface, and described bottom surface has a circular hole passed for drill bit, described sleeve inner has internal thread.
Further, the cylinder of described upper grip block and lower grip block composition is the large Rotary-table in little rear end, front end.
Further, the outline of described sleeve is hexagon.
The utility model has the advantage of:
(1) a kind of drill bit clamping device of the utility model, makes rectangle by drill bit one end, and drill bit grip block center has the rectangular indentation coordinated with drill bit, and drill bit and grip block coordinate tightr, and adopts sleeve locking, convenient and simple.
(2) ensure sleeve and grip block more stubborn tighter, guarantee stability.
(3) hexagonal shape is convenient to general tool clamping installation.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of grip block on a kind of drill bit clamping device of the utility model.
Fig. 2 is the schematic diagram of a kind of drill bit clamping device of the utility model upper bush.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model discloses a kind of drill bit clamping device, comprise grip block 1, lower grip block 3 and sleeve 4, upper grip block 1 and lower grip block 3 are half cylinder that laterally zygomorphic circle centre position has rectangular indentation, two grip blocks form the cylinder that a circle centre position has rectangular indentation 2, have the screw thread linked together outside upper grip block 1 and lower grip block 3; Sleeve 4 is for having the cylindrical shell of bottom surface, and bottom surface has a circular hole passed for drill bit, sleeve 4 inside has internal thread; The cylinder that upper grip block 1 and lower grip block 3 form is the large Rotary-table in little rear end, front end; The outline of sleeve 4 is hexagon.
During use, sleeve 4 is taken off, one end that awl makes rectangle is inserted in the rectangular indentation 2 that above grip block 1 and lower grip block 3 surround, now also there is gap between two grip blocks, drill bit through the circular hole on sleeve 4, sleeve 4 is tightened by the threaded engagement on its internal whorl and clamp, can by spanner, the common tools such as pliers, drill bit is just firmly fixed and has suffered at clamp.
More than show and describe general principle of the present utility model and principal character.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
