Abstract
The invention relates to an extractor. The extractor comprises an extracting head, a pull rod and a handle, wherein the extracting head is detachably connected with the pull rod; a stop block protruding outwards is arranged at the tail part of the pull rod; steps are formed on the inner wall of the handle to form large inner diameter bores and small inner diameter bores; and the handle is arranged into the pull rod along one side of the extracting head. The extractor has a simple structure, is convenient to operate and is time-saving and labor-saving; and cost is reduced; pins are protected from being damaged, thereby ensuring operation safety; even a rusted pin can be easily extracted by the extractor.
Description
Technical field
The present invention relates to a kind of maintenance tool, relate in particular to a kind of extractor.
Background technology
At present, mould or automobile need some parts of dismounting, and the matched in clearance of pin and these parts are tightr when keeping in repair, and removing needs special instrument.Traditional write off submode has following several: 1, directly pin is dug out, such mode makes the pin in the screw destroy, and must open screw again; 2, at the top drilling of pin, pin is ejected, this mode is very accurate to the requirement of perforate, and force position is little, ejects difficulty, needs a large amount of energy of cost, and operating efficiency is low.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of simple in structure, easy to operate, extractor that efficient is high is provided.
For achieving the above object, the technical solution used in the present invention is: a kind of extractor, comprise and take out head, pull bar, handle, described taking-up head removably connects with described pull bar, the afterbody of described pull bar is provided with outwards outstanding limited block, the inwall of described handle is provided with step, forms large diameter hole and little inner diameter hole, and described handle is inserted in described pull bar along a described side of taking out head.
In a preferred embodiment of the present invention, extractor comprises that further the described head that takes out comprises and is provided with the hex nut that externally threaded screw rod and an end are fixed with screw, and described pull bar one end is provided with internal thread, and described screw is connected with described pull rod screw.
In a preferred embodiment of the present invention, extractor comprises that further described handle is dumbbell shaped, and the both ends of described handle are the disk of hollow, and the middle part of described handle is the cylinder of hollow.
In a preferred embodiment of the present invention, extractor comprises that further described limited block fits in the large diameter hole of described handle.
In a preferred embodiment of the present invention, extractor comprises that further the little internal diameter end screw thread that the middle part of described pull bar is close to described handle is fixed with stop nut, and the external diameter of described stop nut is greater than the little internal diameter of described handle.
In a preferred embodiment of the present invention, extractor comprises that further described handle adopts iron or stainless steel material to make.
The invention solves the defective that exists in the background technology, the present invention is simple in structure, and is easy to operate, time saving and energy saving, provide cost savings, and pin can not be damaged, and guaranteed the security of operation, even the pin that gets rusty also takes out easily.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the structural representation of duty of the present invention;
Among the figure: 1, take out head, 2, pull bar, 3, handle, 4, limited block, 5, step, 6, screw rod, 7, hex nut, 8, screw, 9, stop nut, 10, disk, 11, cylinder, 12, the large diameter hole, 13, little inner diameter hole.
The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1 and Figure 2, a kind of extractor, comprise take out 1, pull bar 2, handle 3, described taking-up 1 removably connects with described pull bar 2, the afterbody of described pull bar 2 is provided with outwards outstanding limited block 4, the inwall of described handle 3 is provided with step 5, forms large diameter hole 12 and little inner diameter hole 13, and described handle 3 is inserted in described pull bar 2 along a side of described taking-up 1.
As shown in Figure 2, described taking-up 1 comprises and is provided with the hex nut 7 that externally threaded screw rod 6 and an end are fixed with screw 8, and described pull bar 2 one ends are provided with internal thread, and described screw 6 is threaded with described pull bar 2.When the specification of the object that is removed not simultaneously, screw 6 can be screwed out from pull bar 2, change different screw rods 6.
Further, skid off from pull bar 2 in order to prevent handle 3, the little internal diameter end screw thread that the middle part of described pull bar 2 is close to described handle 3 is fixed with stop nut 9, and the external diameter of described stop nut 9 is greater than the little internal diameter of described handle 3.
The preferred described handle 3 of the present invention is dumbbell shaped, and the both ends of described handle 3 are the disk 10 of hollow, and the middle part of described handle 3 is the cylinder 11 of hollow.Wherein, handle 3 adopts iron or stainless steel material to make, and is wear-resisting and can produce strong wallop.
Further, described limited block 4 fits in the large diameter hole 12 of described handle 3, and when having avoided pulling handle 3, hand slides on the pull bar 2 from handle 3, the danger that hand is crushed by the impact between handle 3 and the pull bar 2.
As shown in Figure 3, when the present invention works, a screw rod 6 that takes out 1 is screwed in the screwed hole of pins, reach enough degree of depth, the cylinder 11 of holding handle 3 middle parts then is toward the motion of pulling direction, and the step 5 of handle 3 inwalls is lived by the end face backstop of the limited block 4 of pull bar 2 afterbodys, pull bar 2 is subjected to clashing into the powerful impact of generation, drive pin toward the motion of pulling direction, pin is taken out smoothly, is deployable maintenance work then.The present invention is not limited to be used for the pin of same specification, can screw rod 6 be made different specifications according to the size of pin internal thread hole.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine technical scope according to the claim scope.
