Description
Technical field
The utility model belongs to electronic element dismounting field of tool, is specifically related to a kind of driver-extractor.
Background technology
Such as relay, microswitch etc., with the electronic component of stitch, in control system, use more and more extensive.Yet when dismantling, can cause sizable trouble at electronic components such as relay and microswitches.The driver-extractor of prior art is mainly comprised of grip folder and claw, rises while pulling out the electronic components such as relay, microswitch, claw is clamped to their bottom, is firmly upwards mentioning grip folder, thereby is realizing separated.But the shortcoming wherein existing is, rises while pulling out and is difficult to exert oneself vertically upward, easily causes the damage of stitch; In addition, need two hands to operate rising while pulling out, a hand is used for mentioning driver-extractor simultaneously, and another hand is used for pinning mainboard, operates more loaded down with trivial details.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of simple in structure, can adopt one-handed performance vertically to extract the driver-extractor of the electronic components such as relay, microswitch.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of driver-extractor, comprises clamping part and support portion, and described clamping part comprises claw, and described claw is movably connected on axle by bearing pin, and the upper end of described claw is provided with tooth; Described axle upper sleeve through has rotating shaft, and the top of described rotating shaft is provided with draw ring, and the middle part of described rotating shaft is provided with screw thread, and described rotating shaft is connected by threaded engagement with described claw; The bottom of described axle is provided with end cap; On described axle, be symmetrically arranged with limit shaft; Described support portion comprises bearing, and the inwall of described bearing offers groove, and described limit shaft can embed institute and tell in groove, realizes being flexibly connected of axle and bearing.
Wherein, the end of described claw is provided with wedge shape hook.
Wherein, the end face of described bearing is offered porose, and the slightly larger in diameter in described hole is in the diameter of axle.
Wherein, when axle in bearing bottom time, the end of described claw is lower than the bottom of described bearing.
Wherein, the bottom of described bearing is provided with rubber blanket.
(3) beneficial effect
Compared with prior art, the utility model is simple in structure, has the operating characteristic of one-handed performance, easy to use, can guarantee vertical direction firmly rising while pulling out, and guarantees to be pulled out the integrality of the stitch of electronic component.

Fig. 1 is the cross-sectional view of the utility model driver-extractor clamping part.
Fig. 2 is the left view of the utility model driver-extractor.
Fig. 3 is the top view of the utility model driver-extractor.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model driver-extractor as Figure 1-3, comprises clamping part and support portion, and described clamping part comprises claw 1, and described claw 1 is movably connected on axle 2 by bearing pin 102, and the upper end of described claw 1 is provided with tooth 103; Described axle 2 upper sleeve throughs have rotating shaft 4, and the top of described rotating shaft 4 is provided with draw ring 401, and the middle part of described rotating shaft 4 is provided with screw thread 402, and described rotating shaft 4 is connected by screw thread 402 with described claw 1; The bottom of described axle 2 is provided with end cap 3; On described axle 2, be symmetrically arranged with limit shaft 201; Described support portion comprises bearing 5, and the inwall of described bearing 5 offers groove 501, and described limit shaft 201 can embed in institute's groove of telling 501, realizes being flexibly connected of axle 2 and bearing 5.
As optimization, the end of described claw 1 is provided with wedge shape hook 101; After the electronic components such as common relay, microswitch are assemblied on mainboard, gap between its bottom and mainboard is less, therefore adopt the design of wedge shape hook 101 is set in claw 1 end, in the gap that can comparatively easily hook 101 be embedded between relay and mainboard, improve the success rate once capturing.
As optimization, it is porose 503 that the end face of described bearing 5 is offered, and the slightly larger in diameter in described hole 503 is in the diameter of axle 2, and therefore described axle 2 can pass freely through hole 503, realizes relative motion freely between axle 2 and bearing 5.
As optimization, when axle 2 in bearing 5 bottom time, the end of described claw 1 is lower than the bottom of described bearing.
As optimization, the bottom of described bearing 5 is provided with rubber blanket 502, and in working the process of pulling out, the bottom of bearing 5 needs and circuit board joint, therefore in the bottom of bearing 5, the effect that rubber blanket 502 can play buffering is set, and prevents that bearing 5 from damaging circuit board.
During use, driver-extractor is placed in to the top of the required electronic component of extracting, claw 1 lays respectively at the both sides of electronic component, then by rotating draw ring 401, drives rotating shaft 4 to turn clockwise.Because the axial location of rotating shaft 4 on axle 2 remains unchanged, so claw 1 spacing between claw under the effect of screw thread 402 reduces gradually, and the wedge shape hook 101 of claw 1 end enters in the gap of electronic component and mainboard and completes holding action simultaneously.Then with a finger, upwards lift ring 401, other fingers prop up bearing 5, in limit shaft 201 embedded grooves 501, have therefore guaranteed that axle 2 moves upward in vertical side, electronic component can be taken off from circuit board, and guarantee the integrality of stitch.
Compared with prior art, the utility model is simple in structure, can adopt one-handed performance, easy to use, can guarantee vertical direction firmly rising while pulling out, and guarantees to be pulled out the integrality of the stitch of electronic component.
These are only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
