Description

Chip extractor with reverse lifting and spacing adjusting functions

Technical Field

The utility model relates to a student practice tool especially relates to electronic component extracting tool.

Background

Most students in colleges and universities or professional technical colleges need to practice the computer and practice the practice. Especially, in the course of programming, the circuit is frequently changed, the chip is repeatedly programmed, the chip is frequently unplugged and plugged, and the chip pins are frequently damaged due to inexperience of students in unplugging the chip. Utility model patent 201320319065.3 discloses a chip puller, which is composed of a left and a right pulling connecting rods 7, 4 and a return spring 2 of a grip clamp (a clamping arm 6, a right clamping arm 3 and a shaft 1) as shown in fig. 1, wherein the bottom end of the elastic grip clamp is bent inwards and is provided with a guide groove, the left and the right pulling connecting rods pass through the guide groove, and the bottom ends of the left and the right pulling connecting rods are provided with a left claw 5 and a right claw 8; when the claw is used, the claws are clamped at two ends of the chip, and the described working principle is that the pulling connecting rod is shorter than the grip clamp, when the grip clamp is held by force, the pulling connecting rod contracts upwards, the bottom of the grip clamp is pressed on a chip mainboard, so that the chip pins are uniformly stressed and separated from the base, and the chip pins are prevented from being bent or broken due to nonuniform stress. However, after the chip extractor is used in the market, the use result is not the same, when the grip clamp is held forcefully, the grip clamp is straightened, the bottom of the grip clamp slides downwards and presses on the chip main board, the false image that the pulling connecting rod contracts upwards in the visual angle is caused to people, and the chip and the base are actually inseparable, so that the chip and the extractor are damaged together. There is a great need for improvements in such chip extractors.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, a chip with adjusting and reverse pulling functions is designed

An extractor.

The technical scheme is that the chip extractor with the functions of adjustment and reverse lifting comprises a holding handle

The left pulling connecting rod and the right pulling connecting rod penetrate through the guide grooves, and the bottom ends of the left pulling connecting rod and the right pulling connecting rod are provided with claws; the elastic grip is characterized in that the grip is an elastic grip, and the bent part of the elastic grip can restore to the original state when the grip is lost; a lifting block is arranged between the left and the right lifting connecting rods, sliding grooves are arranged on two sides of the lifting block, and the lifting block is arranged on the lifting connecting rods through the sliding grooves; corresponding through holes are arranged at the lower parts of the left arm and the right arm of the elastic grip clamp, spacing adjusting bolts are arranged in the through holes, and adjusting nuts are arranged on the bolts.

The utility model discloses a use method and beneficial effect are: when running into the chip that the size is not uniform, can pull up the connecting rod through rotatory adjusting nut with left and right and transfer to with the suitable interval of chip, make the bottom claw insert between chip and the chip seat to tighten the nut and fasten at the chip both ends, hold between the fingers the grip clamp and make the bottom lapse with the claw jointly hold the chip, upwards mention again and carry and draw the piece, because the direction of exerting oneself is concentrated evenly, the chip is easily pulled out from the chip seat, makes the chip stitch have no damage.
