Description
[technical field]
The utility model relates to pin pulling out device, relates in particular to general-purpose pin puller.
[background technology]
The pin removal that uses at present, mostly by dead man, pull out hammer, pull out leadman's handle and pull out and constitute.Pull out head and be welded by the butt joint of two screws, the hidden danger that long-time stressed easy disconnection and causing is hurted sb.'s feelings, and pull out a difficult clamping, time-consuming; When the aperture of pin screw not simultaneously, need to adopt different screws, therefore, then need seek the screw of required external diameter when needing the screw of different-diameter again, use comparatively inconvenience.
[utility model content]
The utility model provides a kind of can pull out required workpiece fast, and pull head highly versatile, security performance are high, is applicable to the general-purpose pin puller of band cap workpiece such as screw, thimble.
In order to realize above-mentioned utility model purpose, the technical scheme that the utility model adopts is:
General-purpose pin puller comprises pull bar and pulls out hammer that the center of pulling out hammer is provided with centre bore, pulls out hammer and is slidingly connected through its centre bore and pull bar, and back end of tie rod is made external diameter and is used for pulling out the spacing limiting section of hammer greater than pulling out hammer centre bore aperture; Said pull bar lower end is connected with pull head, and pull head is provided with and holds the pull pin groove of part of cap body class, and the groove downside is provided with and can engages the pull pin horizontal draw-in groove of part of different-diameter cap body class.
Said pull bar front end is provided with external screw thread, and the top of said pull head is provided with the internal thread that cooperates with pull bar front end external screw thread.
Said pull bar and said pull head are integral structure.
Preferably, said draw-in groove is not wide to the blind end spacing from openend, makes draw-in groove can directly engage the attaching the names of pre-determined candidates type workpiece of diameter in the certain limit size, thereby increases the scope of application of single pull head.
Preferably, said draw-in groove diminishes to the blind end spacing from openend gradually, and such opening makes that engaging is more convenient, saves the time that the frequent change pull head is wasted.
Said draw-in groove is V-arrangement draw-in groove or dovetail groove, can be so that the engaging effect of type of attaching the names of pre-determined candidates workpiece is reached better.
The beneficial effect of the utility model is:
The pull head of the utility model pin removal head can not rupture easily, the potential safety hazard that has overexerted and brought when having stopped to use pin removal; Behind the pin removal pull bar lengthening, the user of service can pull to waist portion side with pulling out hammer, has stopped to bump against the hidden danger of chest or lower jaw; Horizontal draw-in groove on the pull head, the cap body class that can the engage different-diameter part of pulling pin is not limited to screw, and the workpiece of band such as thimble cap can quick-clamping, pulls out the workpiece that need pull out rapidly.

Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the amplification stereogram of the utility model pull head;
Fig. 4 is the three-dimensional user mode figure of the utility model.
[specific embodiment]
Extremely shown in Figure 4 like Fig. 1; General-purpose pin puller comprises pull bar 1 and pulls out hammer 2 that the center of pulling out hammer 2 is provided with centre bore 20; Pull out hammer 2 and be slidingly connected through its centre bore 20 and pull bar 1, pull bar 1 rear end makes external diameter and is used for pulling out the spacing limiting section 10 of hammer 2 greater than pulling out hammer 2 centre bores 20 apertures; Pull bar 1 lower end is connected with pull head 3, at pull bar 1 front end external screw thread is set, and the top of pull head 3 is provided with the internal thread that cooperates with pull bar 1 front end external screw thread; Pull head 3 is provided with and holds the pull pin groove 30 of part of cap body class, and groove 30 downsides are provided with and can engage the pull pin horizontal V-shaped draw-in groove 31 of part of different-diameter cap body class.
The utility model pull bar 1 length is set between 70～100CM, and pull head 3 is arranged to the hollow bulk, and an end is set to internal thread, and the other end is set to horizontal V-shaped draw-in groove 31.During use pull head 3 and pull bar 1 are passed through screw-threaded coupling; Then pull head is engaged through horizontal V-shaped draw-in groove 31 with the workpiece that need pull out or screw, the user stands in pull bar 1 one sides, and one holds pull head 3; Another holds and pulls out hammer 2; Pulling is pulled out hammer 2 and on pull bar 1, is slided, and makes the limiting section 10 that pulls out hammer 2 bump pull bars 1 rear end, thereby pull bar 1 is pulled out workpiece or screw; Horizontal V-shaped draw-in groove 31 can directly engage the attaching the names of pre-determined candidates type workpiece of diameter in the certain limit size; Thereby increase the scope of application of single pull head 3; Simultaneously, the opening of horizontal V-shaped draw-in groove 31 makes that also engaging is more convenient, saves the time that frequent change pull head 3 is wasted.
The above embodiment just is the preferred embodiment of the utility model, is not the practical range that limits the utility model with this, and the equivalence that all shapes according to the utility model, structure and principle are done changes, and all should be covered by in the protection domain of the utility model.
