Description
Technical field
The utility model belongs to the dead man technical field of tools, is specifically related to a kind of rod-pulling device of dismantling pin rod or nail.
Background technology
Stalk pulling device, on some documents, also referred to as nail extractor, the nail extractor of prior art is to adopt the pry type structure mostly, namely establishes prong at the front end of ripping bar, lives nail with the prong fork, the recycling lever principle levers up nail.
China Patent No. ZL201020623998.8 for example, name is called the utility model patent of " a kind of nail extractor ", a kind of nail extractor is disclosed, comprise base, pole, depression bar and handle, described base upper surface middle part is fixedly connected with pole, and described pole top has groove, hinged depression bar in groove, described depression bar one end is fixedly connected with a rectangle plate body, other end connecting handle.This utility model utilizes the v-shaped openings of rectangle plate body front end to live nail with fork, then utilize lever principle that nail is levered up, this nail pulling scheme can't be used for cylindrical bar one class part, because the cylinder component of rod category is not similar to the such head of nail for levering up; Secondly, the nail for long because ripping bar can not extend, makes nail pull out half length and just can't continue to pull up later.
China Patent No. ZL200710011930.7 and for example, name is called the patent of invention of " dynamic nail extractors ", discloses a kind of dynamic nail extractors, dop with bayonet is arranged, dop upper end and screw rod active connection of lower end, screw rod upper end are with power sub, and screw rod overlaps movingly threaded sleeve; The bayonet socket of dop is stuck in below the head of a nail, and the power sub of screw rod upper end is connected with the power engine of rotation, and the rotation of engine drives bolt rotary, and screw rod rotates shipper pole relative to screw shell and moves on dop and nail and move, and vertically extracts nail; The threaded sleeve lower surface is patterned surface or toothed surface or corrugated surface, increases the frictional force of screw shell and the material such as wooden around nail, the reliability of increase nail pulling.This invention utilizes the bayonet socket of dop to be stuck in below the head of a nail, then dop is up promoted by the screw thread transmission with power set, and problem is that its bayonet socket is horizontal inverted trapezoidal groove.This invention exists for the cylinder component of rod category that is not similar to the such head of nail such as pin one class, due to can't clamping and out of use defective.
China Patent No. ZL200710012992.X for another example, name is called the patent of invention of " hydraulic power nail extractor ", the principle of its nail pulling is basic identical with " dynamic nail extractors ", just power specifically is made as hydraulic coupling, and the clamping ailhead is the inverted trapezoidal groove equally, therefore also has the same defective that can not pull out the cylinder component of rod category.
Summary of the invention
The utility model technical issues that need to address are, the nail extractor that overcomes prior art exists to rise and pulls out cylinder component of rod category or simple outer standby power source or the little defective of clamping dynamics of relying on, provide a kind of and can work the stalk pulling device that pulls out straight pin class part, no matter this stalk pulling device is for being that cylindrical bar or nail can powerful clampings and pull up fast, and simple in structure, clamping is reliable, easy to operate, but can be manually also mobile operation.
The purpose of this utility model is achieved by following technical proposals: a kind of omnipotent stalk pulling device comprises basic socket, clamping bar mechanism and boosts mechanism; The inboard, bottom of basis socket is downward opening taper cone barrel structure, and the upper surface of basic socket is fixedly connected with hammering retaining board, and the centre of hammering retaining board is provided with through hole; Clamping bar mechanism comprises spring-loaded pawl, the outer surface of spring-loaded pawl is provided with taper seat, and this taper seat coordinates separably with described taper cone barrel structure, and the rearward end of spring-loaded pawl is connected with suspension rod, suspension rod coordinates with the via clearance of hammering retaining board centre, and the upper end of suspension rod is provided with and hangs tight mechanism; Boost mechanism and comprise that activity is engaged in the weight pipe of basic socket outside, the upper surface of weight pipe is corresponding with the lower surface of hammering retaining board.
spring-loaded pawl is enclosed within on bar to be pulled pin or nail head, then hang tight spring-loaded pawl with hanging tight mechanism, spring-loaded pawl is because the taper seat of its outer surface is locked along moving on the taper cone barrel structure of basic socket, this coupling mechanism force of utilizing inclined plane principle to amplify is very large, can guarantee firmly to clamp pin rod, even a fine needle also has enough clamping forces, then by manual or mobile operation, the weight pipe is moved upward fast along basic socket, utilize the upper end of weight pipe to clash into hammering retaining board, cause that basic socket moves up, reach by basic socket and drive the effect that is also moved up together by the pin rod of spring-loaded pawl clamping, working time of collision during due to shock is extremely short, under certain Impulse, impulsive force size with become to be similar to the increase of inversely proportional relation action time, this impulsive force is passed to the fixed position of pin rod, can make pin rod loosening fast, then continued to clash into and extracted, this omnipotent stalk pulling device all is suitable for for the various cylinder pin rods of random length, not only have power and unload greatly and fast the characteristics of bar, the pry type nail extractor that can also avoid prior art is pressed and is made the impaired defective of pedestal or plank surface due to the top of ripping bar fulcrum location, realize since utilize when beaing nail or pin rod from top to bottom to clash into, will extract now nail or pin rod and might as well act in a diametrically opposite way, namely catch nail or pin rod to clash into from lower to upper, the method rationally and very effective.
As preferably, described spring-loaded pawl is provided with six impartial lobe claws.
