Abstract
A chip extractor belongs to the technical field of electronic element disassembling tools. The rotary shaft is connected and fixed by a return spring, two arms of the return spring are respectively clamped in an inner side groove of a left grip clamp and an inner side groove of a right grip clamp, one end of a left pulling connecting rod is connected with the fixed rotary shaft, the other end of the left pulling connecting rod is connected with a ground foot of the right grip clamp, one end of a right pulling connecting rod is connected with the fixed rotary shaft, the other end of the right pulling connecting rod is connected with the ground foot of the left grip clamp, one end of the left pulling connecting rod is provided with a claw, one end of the right pulling connecting rod is provided with the claw, the claw is provided with 2 sharp corners with intervals of 2-3mm, and the claw is provided with 2 sharp corners with intervals of 2-3 mm. When the chip is used, the claws are clamped at two ends of the chip, the pulling connecting rods are shorter than the grip clamps, when the grip clamps are held forcefully, the pulling connecting rods shrink upwards, the bottom of the grip clamps are pressed on a chip mainboard, so that chip pins are uniformly stressed and separated from the base, and the chip pins are prevented from being bent or broken due to uneven stress.
Description
Technical field
The utility model relates to a kind of extraction tool, belongs to the electronic element dismounting technical field of tools.
Background technology
In society, nearly all equipment has control chip, but, when chip damages or need to change chip program, has needed to pull out unavoidably the chip on circuit main board.The extraction tool of prior art all mainly by grip folder, fixed rotating shaft, rise and pull out several parts of connecting rod, claw and return spring and form.Grip folder, rise and pull out connecting rod and return spring all is connected on fixed rotating shaft, rise to pull out below connecting rod and only have a claw, when playing the depoling sheet, will work the claw pulled out on connecting rod and be clipped in respectively the two ends of chip, firmly hold the grip folder, the stitch of chip can be separated and pulls out with base.But when the shortcoming of existing driver-extractor has been the depoling sheet, pulls out on connecting rod and only have a claw due to single, easily cause the stitch discontinuity, the stitch of defective chip, the phenomenon even stitch fractureed.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of extraction tool.
The technical problem that the utility model solves just is to provide a kind of one and rises and pull out on connecting rod the extraction tool that two claws are arranged, and can allow the chip uniform stressed, prevents that stitch from damaging.
A kind of extraction tool, return spring is connected and fixed rotating shaft, two arms of return spring are stuck in the inboard groove of left grip folder, in the inboard groove of right grip folder, an end that pulls out from left to right connecting rod is connected and fixed rotating shaft, the other end that pulls out from left to right connecting rod connects the lower margin of right grip folder, an end that pulls out from right to left connecting rod is connected and fixed rotating shaft, the other end that pulls out from right to left connecting rod connects the lower margin of left grip folder, an end that pulls out from left to right connecting rod has the first claw, an end that pulls out from right to left connecting rod has the second claw, the second claw has the wedge angle that 2 spacings are 2-3mm, the first claw has the wedge angle that 2 spacings are 2-3mm.
The utility model has the advantages that to make the chip stitch stressed evenly, can not cause the crooked of stitch or fracture, therefore there is practicality and generalization widely.
The accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to following, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model, for explaining the utility model, does not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of extraction tool, return spring 1 is connected and fixed rotating shaft 2, two arms of return spring 1 are stuck in the inboard groove of left grip folder 3, in the inboard groove of right grip folder 6, an end that pulls out from left to right connecting rod 4 is connected and fixed rotating shaft 2,, the other end that pulls out from left to right connecting rod 4 connects the lower margin of right grip folder 6
An end that pulls out from right to left connecting rod 7 is connected and fixed rotating shaft 2, and the other end that pulls out from right to left connecting rod 7 connects the lower margin of left grip folder 3,
An end that pulls out from left to right connecting rod 4 has the first claw 8, and an end that pulls out from right to left connecting rod 7 has the second claw 5, the second claws 5 that the wedge angle that 2 spacings are 2-3mm is arranged, and the first claw 8 has the wedge angle that 2 spacings are 2-3mm.
In use, the first claw 8, the second claw 5 are clipped in to the two ends of chip, pull out connecting rod 4 and press from both sides 3 short than grip owing to rising, firmly grip is pressed from both sides 3 o'clock, rise and pull out upwards contraction of connecting rod 3, grip folder bottom is pressed on the chip mainboard chip stitch uniform stressed is separated with base, prevents that unbalance stress from causing the bending of chip stitch or fractureing.
As mentioned above, embodiment of the present utility model is explained, but, as long as not breaking away from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation also all is included in protection domain of the present utility model.
