Abstract
Disclosed is a U-shaped pin pull-out device. The U-shaped pin pull-out device comprises a strip-shaped steel plate. A small elbow which is upwards bent is arranged at one end of the strip-shaped steel plate, and is mainly used for pulling small U-shaped pins out. A large elbow which is downwards bent is arranged at the other end of the strip-shaped steel plate. A protrusion is arranged on the portion, close to the sharp portion, of the left side of the small elbow, and a protrusion is arranged on the portion, close to the sharp portion, of the right side of the large elbow. The steel plate is a stainless steel plate. Due to the facts that existing methods that U-shaped pins are pried by a screwdriver, a vice is matched with the screwdriver to pull the U-shaped pins out, and the U-shaped pins are knocked by a hammer can be changed, and the U-shaped pins can be pulled out by a special tool, the pull-out effect can be effectively improved, and the situation that a worker is bruised or scratched can be avoided.
Description
Technical field
The present invention relates to pulling tool, particularly a kind of U-shaped pin driver-extractor.
Background technology
How connecting between connection and above-mentioned pipeline and the terminal unit between the sebific ducts such as the interim hydraulic tube in down-hole, airduct, water pipe is realized by the snap joint that bite type is straight-through and sebific duct two ends are fixing, after bite type is straight-through and snap joint connects, it is necessary for fixing with U-shaped pin.When fixing with U-shaped pin, insert very convenient, beat gently with instrument after insertion and just can make U-shaped pin fix in position.But when interim pipeline or terminal unit such as air drill, pneumatic pick etc. use complete, it is necessary for removing pipeline in time or reclaiming terminal unit, at this moment inevitably runs into the problem that U-shaped pin removes difficulty.
When removing U-shaped pin, great majority are to use screwdriver sled to coordinate the mode that vice pulls out, hammer strikes to be tripped out to pull out, due to the U-shaped pin fixing compact of part or in use flexural deformation, often lead to remove unsuccessfully, and screwdriver also produces flexural deformation in the process of sled of being everlasting；Strike with a hammer and not only easily hurt hands, and easy damaged cutting ferrule, joint；Simultaneously the labor intensity of operator is big, the situation such as process of pulling pin complexity, efficiency is low, easy damages, scuffing.
Summary of the invention
Present invention solves the technical problem that being to provide one can make the U-shaped pin of dismounting convenient, improves the U-shaped pin driver-extractor of safety coefficient.
The technical scheme is that and so complete that a kind of U-shaped pin driver-extractor includes bar steel plate, one end of bar steel plate is set to the eyesight elbow being bent upwards, be mainly used in pulling out small-sized U-shaped pin.
It is preferred that embodiment, the other end of described bar steel plate is set to reclinate big elbow, has been mainly used in pulling out large-scale U-shaped pin.
It is preferred that embodiment, it is provided with projection near tip place on the left of described eyesight elbow, slides on eyesight elbow principally for U-shaped pin when having prevented from pulling out U-shaped pin, improved further and pulled out effect.
It is preferred that embodiment, it is provided with projection near tip place on the right side of described big elbow, slides on big elbow principally for U-shaped pin when having prevented from pulling out U-shaped pin, improved further and pulled out effect.
It is preferred that embodiment, described steel plate is corrosion resistant plate, is primarily to and prevents from getting rusty, and improves aesthetic property.
The solution have the advantages that: coordinate that vice pulls out, hammer rings and pulls out U-shaped pin method owing to the present invention can change original screwdriver sled, rise with specific purpose tool and pull out U-shaped pin, namely can be effectively improved and pull out effect, it is also possible to prevent from damaging, the situation such as scuffing.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment one: as it is shown in figure 1, a kind of U-shaped pin driver-extractor, including bar steel plate 2, one end of bar steel plate 2 is set to the eyesight elbow 1 being bent upwards.The camber line of eyesight elbow 1 left and right sides intersects at tip, is so provided with and is beneficial to the present invention and inserts the contact position between U-shaped pin and fixture.
Embodiment two: as it is shown in figure 1, on the basis of embodiment one, the other end of described bar steel plate 2 is set to reclinate big elbow 4.The camber line of big elbow 4 left and right sides intersects at tip, is so provided with and is beneficial to the present invention and inserts the contact position between U-shaped pin and fixture.
Embodiment three: as in figure 2 it is shown, on the basis of embodiment one or two, be provided with protruding 5 near tip 5 place on the left of eyesight elbow 1.
Embodiment four: as in figure 2 it is shown, on the basis of embodiment three, be provided with protruding 7 near tip 8 place on the right side of described big elbow 4.
Embodiment five: on the basis of embodiment four, steel plate is corrosion resistant plate.
Hanging to tool rack after carrying with for convenience of operating personnel and use, steel plate left end is provided with lanyard hole 3.
During use, the space between leading directly to the tip of one end of the present invention U-shaped pin bending section of insertion and bite type, using the corresponding site of fixture as the strong point, the other end grasping the present invention is exerted oneself downwards, can be pulled out by U-shaped pin.The big elbow of large U type pin.Little U-shaped pin eyesight elbow.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, also should be regarded as protection scope of the present invention.
