Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of broken-end screw taking-out device, including shell 1, side side wall of the shell 1 far from silk fetching equipment 15 are perpendicular
It is directly equipped with handle 20, shell 1 is held convenient for hand, positive and negative driving motor 2 is equipped in shell 1, the outside of shell 1 is equipped with and positive and negative drive
The matched drive block 3 of output shaft of dynamic motor 2, drive block 3 are arranged with dust cover at shell 1, prevent dust from penetrating and run through
The gap at place enters in shell 1, and drive block 3 is arranged through the side wall of shell 1, and drive block 3 is hollow structure, drive block 3
Bottom the bull stick 5 being vertically arranged is rotatably connected to by the first rotating member 4, bull stick 5 is hollow structure, and two are equipped in bull stick 5
A plectrum 16, and plectrum 16 runs through and extends to the outside setting of bull stick 5, is connected by multiple springs 17 between two plectrums 16
It connects, the one end for being located at the plectrum 16 in bull stick 5 is equipped with kelly 18, and kelly 18 is arranged through the side wall of bull stick 5, the side of shell 1
Wall is equipped with can prevent the voluntarily rotation due to bull stick 5 from causing fixture block 14 to silk fetching equipment with 18 matched card slot 19 of kelly, this structure
15 clamping force relaxation, therefore two plectrums 16 are first pinched before rotation bull stick 5 every time, spring 17 is compressed and is provided with elastic force,
Kelly 18 is detached with card slot 19 and is retracted in bull stick 5, and at this moment bull stick 5 can rotate, and after unclamping plectrum 16, the bullet of spring 17
Power flicks two plectrums 16, and kelly 18 is clamped with card slot 19 again, and at this moment bull stick 5 is fixed, and rubber is enclosed on bull stick 5
Protective case prevents from abrading hand when rotation, and bull stick 5, through the upper end side wall setting of drive block 3,5 sidewall sheath of bull stick is equipped with two
The both sides inner wall of a first helical gear 6, drive block 3 is rotatably connected to the threaded rod 8 being vertically arranged by the second rotating member 7,
And the one end of threaded rod 8 far from the second rotating member 7 is equipped with and 6 matched second helical gear 9 of the first helical gear, two threaded rods 8
Side wall be arranged with matched nut 10, shell 1 sets that there are two sliding slots 11, and sliding slot 11 close to the side wall of threaded rod 8
Fixture block 14 is slidably connected by sliding block 12,12 side wall of sliding block is also connect by the connecting rod 13 being laterally arranged with nut 10, and two
Silk fetching equipment 15 is equipped between a fixture block 14.
It when utility model works, is first spiled with the drill bit smaller than screw, after the completion of hole to be drilled, pinching plectrum 16 makes card
Bar 18 is detached with card slot 19, rotates bull stick 5, and bull stick 5 drives two the first helical gear 6 rotations, the first helical gear 6 and the second helical teeth
9 engagement of wheel, the second helical gear 9 drives threaded rod 8 to rotate, since nut 10 is connect by connecting rod 13 with sliding block 12, and sliding block 12
It can only be slided in sliding slot 11, therefore nut 10 can move on threaded rod 8, nut 10 is driven by connecting rod 13 and sliding block 12
Fixture block 14 moves, and fixture block 14 clamps silk fetching equipment 15, and then positive and negative driving motor 2 drives drive block 3 to rotate, 3 band of drive block
15 forward or reverse of dynamic silk fetching equipment, so that silk fetching equipment 15 takes off screw.
