Carry inconvenience, also result in the wasting of resources simultaneously.For the screw that position is the deepest, owing to having away from too far away or space
Limit uses common screwdriver to reach.
Utility model content
The purpose of this utility model is to provide a kind of telescopic Spring screws cutter, and simple in construction is easy to carry, Ke Yi
Any switching laws in two kinds of specification limits, improves work efficiency, saves resource, solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
A kind of telescopic Spring screws cutter, comprises outer knife bar, J-type chute, handle, interior knife bar, spring, card column, cutter head
One and cutter head two, described outer knife bar is hollow-core construction, and one end of outer knife bar is vertically set on handle, and the other end is provided with cutter head
One, outer knife bar is provided with J-type chute；Described interior knife bar is arranged on the inside of outer knife bar, and one end is adjacent with handle, and the other end is provided with
Cutter head two, cutter head two is adjacent with cutter head one, and mates setting；Described card column is two, is symmetricly set on up and down the two of interior knife bar
Side, is fastened on the top of J-type chute, and the diameter of card column matches with the width of J-type chute；The outside of described interior knife bar is arranged with
Spring, one end of spring is fastened in two card columns, and the other end is near cutter head two；Described outer knife bar, handle, interior knife bar and spring
Arranged concentric on the same axis.
Described cutter head one and cutter head two are cross cutter head.
The beneficial effects of the utility model: performance flexibly, reliable, can be with two kinds of specifications of any switching laws, it is to avoid for not
The screw of same specification needs to change frequently the drawback of the screwdriver of correspondence, improves work efficiency.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is that knife bar stretches out schematic diagram in this utility model；
Fig. 3 is that this utility model right side regards sectional view；
In figure: outer knife bar 1, J-type chute 2, handle 3, interior knife bar 4, spring 5, card column 6, cutter head 1, cutter head 28.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of telescopic Spring screws cutter, comprises outer knife bar 1, J-type chute 2, handle 3, interior knife bar 4, spring 5, card column
6, cutter head 1 and cutter head 28, described outer knife bar 1 is hollow-core construction, and one end of outer knife bar 1 is vertically arranged on the handle 3, another
End is provided with cutter head 1, and outer knife bar 1 is provided with J-type chute 2；Described interior knife bar 4 is arranged on the inside of outer knife bar 1, one end and handle
3 is adjacent, and the other end is provided with cutter head 28, and cutter head two is adjacent with cutter head one, and mates setting；Described card column 6 is two, and symmetry sets
Putting the both sides up and down at interior knife bar 4, be fastened on the top of J-type chute 2, the diameter of card column 6 matches with the width of J-type chute 2；
The outside of described interior knife bar 4 is arranged with spring 5, and one end of spring 5 is fastened in two card columns 6, and the other end is near cutter head two；Institute
State outer knife bar 1, handle 3, interior knife bar 4 and spring 5 arranged concentric on the same axis.
Described cutter head 1 and cutter head 28 are cross cutter head.
During use, for the screw of big specification, the cutter head 1 on available outer knife bar 1 directly operates.For small dimension
Screw, it is the most drop-down that available thumb and forefinger nip card column 6, makes the 6 times pressing springs 5 of card column J-type chute 2 along outer knife bar 1
Slide, when moving the end to, the bearing of trend along J-type chute 2 moves, and looses one's grip, card column 6 under the effect of spring 5 on bullet, be fixed on J-type
The bottom of chute 2, makes interior knife bar 4 stretch out.Then the cutter head 28 that in using, knife bar 4 stretches out under state operates, it is to avoid for
The screw of different size, frequently changes corresponding screwdriver.
