Detailed Description
Referring to fig. 1-4, a staple remover specially used for staples comprises a rotary sleeve 20, wherein a screw hole is formed in the center of the rotary sleeve 20, a screw 10 is screwed into the screw hole, a groove is formed in the rotary sleeve 20, a fixing portion 32 of a support frame 30 is clamped in the groove, and a gap is formed between the fixing portion 32 and the rotary sleeve 20, and the gap meets the requirement of relative rotation of the rotary sleeve 20 and the support frame 30.
Referring to fig. 1, the upper end of the screw 10 fixes the grip 11, the lower end of the screw 10 fixes the connecting block 12, the lower surface of the connecting block 12 fixes the upper ends of the first leg 13 and the second leg 14, and the lower ends of the first leg 13 and the second leg 14 fix the insertion portion 15.
As shown in fig. 4, the insertion portion 15 includes a left insertion portion 151 and a right insertion portion 152, the left insertion portion 151 and the right insertion portion 152 are respectively fixed to the first leg 13 and the second leg 14, the left insertion portion 151 is tapered outward from the base portion and is provided with an inward recessed portion 153 at the outer portion thereof, the right insertion portion 152 is tapered outward from the base portion and is provided with a tip portion 154 at the outer portion thereof, and the tip portion 154 can enter the inward recessed portion 153, thereby completing the insertion of the insertion portion.
As shown in fig. 3, the upper end of the supporting frame 30 is a fixing portion 32, the fixing portion 32 is ring-shaped, a through hole 31 is formed in the middle, the through hole 31 is used for the screw rod 10 to pass through, two legs 33 are fixed on the fixing portion 32, and the legs 33 are inverted and shaped like a door.
As shown in fig. 2, the rotary sleeve 20 is divided into a left semicircular part and a right semicircular part 21, the left semicircular part and the right semicircular part 21 are both provided with two sets of corresponding threaded holes, each set of threaded holes penetrates through the fixing screw 22, one side of the fixing screw 22 is in threaded fit with the nut 24, the other end of the fixing screw is in threaded fit with the nut 25, and the end extends outwards to form the fixing handle 23.
As shown in fig. 1, the first leg 13 and the second leg 14 are both provided with a sliding ring 40, the two sliding rings 40 are fixed by a connecting rod 41, and a pressing portion 42 is fixed in the radial direction of the sliding ring 40.
For the self-firmness, the rotary sleeve 20, the support frame 30, the screw rod 10, the connecting block 12, the first leg 13, the second leg 14 and the inserting part 15 are made of metal, and the fixing between the screw rod 10 and the connecting block 12, between the connecting block 12 and the first leg 13 and the second leg 14 and between the inserting part 15 and the first leg 13 and the second leg 14 are all welded.
The holding part 11 is in a cross shape or a rice shape.
The working principle is as follows:
when the device is needed to be used, the pressing and holding part 42 is held, the two slip rings 40 are moved to the upper parts of the first supporting leg 13 and the second supporting leg 14, the lower ends of the first supporting leg 13 and the second supporting leg 14 are outwards opened by two hands, the left insertion part 151 and the right insertion part 152 are separated, and the two insertion parts are close to the gap between the staple and the paper; then, the hands are released, and the first and second legs 13 and 14 are returned, so that the left and right insertion portions 151 and 152 enter the gap between the staple and the sheet.
At this time, the press-holding portion 42 is gripped again, and the two slide rings 40 are moved to the lower portions of the first leg 13 and the second leg 14, so that the left insertion portion 151 and the right insertion portion 152 are prevented from being separated.
Finally, one hand holds the holding part 11 and the other hand holds the handle 23 to rotate the rotary sleeve 20, so that the rotary sleeve 20 and the screw 10 rotate relatively (in the process, the support frame 30 does not rotate along with the rotary sleeve 20), and meanwhile, the screw 10, the rotary sleeve 20 and the support frame 30 are displaced axially, namely, the support frame 30 moves downwards.
With the continuous rotation, the supporting frame 30 abuts against the paper and cannot move downwards continuously; the screw 10 is further rotated to be forced to move upward together with the link block 12, the first leg 13, the second leg 14, the insertion portion 15, and the staple, so that the staple is separated from the paper, and the staple raising operation is completed.
See the prior art for additional details.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
