Abstract

The invention relates to a screw assembling and disassembling tool, which comprises a holding part and a driving part, wherein at least one feeding axial hidden groove is formed on the contact surface of the driving part and a screw head, and a linear elastic buckle is embedded in the feeding axial hidden groove; when the driving part feeds to the screw head, the linear elastic buckle is gradually pushed inwards along with the feeding of the driving part and continuously abuts against the screw head, so that the screw can be buckled on the driving part by the linear elastic buckle and cannot fall off when the screw is assembled and disassembled. Therefore, the problem that the screw is easy to fall off when the screw is assembled and disassembled in the prior art is solved, and the screw is not easy to fall off and is convenient to use when the screw is assembled and disassembled.

Description

Mounting/dismounting screw tool instrument

Technical field

The present invention is relevant a kind of mounting/dismounting screw tool instrument, espespecially a kind of when loading and unloading screw screw not easily drop and use design smoothly.

Background technology

Screw is for fixing an object or engaging two objects, and screw comprises the larger screw terminal of diameter and the less screw body of diameter, screw body surface forms irregular screw thread, screw terminal common are circular, the square or regular hexagon of interior hexagonal, can use spanner rotation screw, if screw terminal is dome, end face also has rill, the screwdriver rotation screw of correspondence easy to use, modal rill has yi word pattern and cross and square; But traditional mounting/dismounting screw tool instrument (spanner or screwdriver) is in time loading and unloading screw, and screw very easily drops, if screw drops and will be difficult to bring back in the gap of facility, serious, the screw dropped may affect the normal operation of facility.

Secondary person, as shown in Figure 1 and Figure 2, TWI370760 discloses a kind of screwdriver 1, be the tool lock section of pulling 12 in bottle opener main body 11 front end, caulking groove 13 is equipped with again in the lock section of pulling 12 right position place, and be arranged with a jack in this caulking groove 13 bottom land radial direction, the another ring 14 being arranged with tool flexibility in caulking groove 13, and make this ring 14 one end circle be around in caulking groove 13, ring 14 another end then bends the section of supporting 141 being formed with and stretching out outside the lock section of pulling 12, under making this ring 14 another end end by vertical extension of the section of supporting 141 again, stretch in jack set by caulking groove 13 bottom land; Whereby, when the lock section of pulling 12 of screwdriver 1 is inserted in screw groove 21, the section of supporting 141 of this flexible ring 14 just can support in screw groove 21, and makes screw 2 can be positioned the lock section of pulling 12 of screwdriver 1, is locked reposefully in object by screw with convenient user's one hand.But, due to this flexible ring 14 to arrange the feed shaft that axially (illustrated Y-axis) and this lock section of pulling 12 plant to screw groove 21 vertical to (illustrated X axis), cause this section of supporting 141 stretched out outside this lock section of pulling 12 can't be pushed inwardly gradually to the plant of screw groove 21 along with this lock section of pulling 12, this lock section of pulling 12 directly can clash into the apical margin of this screw 2 because this lock section of pulling 12 of projection is outer, cause this lock section of pulling 12 to the plant process of screw groove 21 and have some setbacks, even be difficult to plant, the screwdriver of this Patent Case is used not smoothly.

Summary of the invention

For solving the prior art problem that screw very easily drops in time loading and unloading screw, the invention provides a kind of mounting/dismounting screw tool instrument, it has effect that when loading and unloading screw, screw not easily drops, and has use effect smoothly.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of mounting/dismounting screw tool instrument, includes grip part and drive division, and makes the contact surface of this drive division and screw terminal at least form a feed shaft to disappearing groove, and a wire snap-on is embedded at this feed shaft to disappearance groove.

In addition, this feed shaft is greater than the wire diameter of this wire snap-on to the groove width of disappearing groove, and is located by this wire snap-on buckle in this feed shaft to formation buckle portion, disappearance groove two ends.But this handling instrument is spanner or bottle opener; Wherein, this handling instrument is inner hexagon spanner, plum drives spanner, a word bottle opener, cross driver or star bottle opener; Or this handling instrument is a word bottle opener, and this feed shaft is a horizontal shape disappearance groove below feeding axial port word removes to disappearance groove, and this feed shaft is a horizontal shape disappearance groove below this feeding axial port word removes to disappearance groove; Another person, this handling instrument is cross driver, and this feed shaft is formed to disappearance groove the junction that wantonly two of this drive division drives shaft of rib.

The invention has the beneficial effects as follows, it has effect that when loading and unloading screw, screw not easily drops, and has use effect smoothly.
