Description

A kind of socket hexagon socket head cap screw and special spanner thereof

Technical field

This utility model relates to machine tool technical field, particularly relates to a kind of socket hexagon socket head cap screw and Special pull thereof Hands.

Background technology

The most common hexagon socket head cap screw comes with some shortcomings in use, the installation and removal of such as hexagon socket head cap screw Spanner have to be coordinated to use, and a common word spiral shell cutter is just difficult to use；It addition, when the screw terminal of hexagon socket head cap screw is sliding During tooth, it is difficult to be disassembled with existing instrument, inconvenient operation.

Utility model content

In order to solve the problems referred to above that prior art exists, this utility model provides one can efficiently solve screw The problem being difficult to after the sliding tooth of head dismantle, also can coordinate simultaneously socket hexagon socket head cap screw that the instruments such as a word spiral shell cutter carry out using and Special spanner.

The technical scheme that this utility model is used is: a kind of socket hexagon socket head cap screw, including screw terminal be arranged on institute State the screw rod of screw terminal afterbody, the center of described screw terminal offers hexagon blind hole, described hexagon blind hole interior Offering groove on sidewall, one end of described groove is arranged on the end of described screw terminal.

Further, each medial wall of described hexagon blind hole is provided with described groove.

Further, described groove radially distributes with the center of described hexagon blind hole.

Further, at least the sideline, end of two described grooves is located on the same line.

A kind of socket hexagon socket head cap screw special spanner, is hexagonal wrench body including cross section, described wrench body Match with described blind hole, the sidewall of described wrench body is provided with and the projection of described groove match.

Further, each sidewall of described wrench body is provided with described projection.

Further, described projection radially distributes with the center of described wrench body hexagonal cross-section.

Further, at least the sideline, end of two described projections is located on the same line.

The beneficial effects of the utility model are: by arranging groove on screw terminal, make the installation of socket hexagon socket head cap screw With dismounting convenient, with its with the use of instrument more diversified, both can select common spanner, one can have been selected again Word spiral shell cutter, it is also possible to select socket hexagon socket head cap screw special spanner to operate, use wider, simultaneously processing groove Technique is simple, will not improve its manufacturing cost.

When the sliding tooth of screw, common spanner is difficult to dismantle it, by socket hexagon socket head cap screw special spanner just Can be disassembled easily, the most time saving and energy saving but also simple efficient；And the other end of socket hexagon socket head cap screw special spanner with Common spanner is the same, therefore can be used for mounting and dismounting common screw, improves its service efficiency.

Detailed description of the invention

As it is shown in figure 1, this utility model provides a kind of socket hexagon socket head cap screw, including screw terminal 1 be arranged on screw The screw rod 2 of 1 afterbody, the center of screw terminal 1 offers hexagon blind hole 11, the medial wall of hexagon blind hole 11 is opened Being provided with groove 12, one end of groove 12 is arranged on the end of screw terminal 1.By arranging groove 12, make and socket hexagon socket head cap screw Carry out with the use of instrument more diversified, both can use special spanner with matching, can make again common wrench or The conventional tool such as one word spiral shell cutter, it is often more important that when the sliding tooth of screw terminal, between adjacent two medial walls of hexagon blind hole 11 Becoming rounding off, even hexagon blind hole 11 has changed into the shape close to circular hole, now through repeatedly installation and removal When using common spanner, frictional force reduces, and is difficult to be disassembled, and the groove 12 on socket hexagon socket head cap screw can have Prevent to effect the generation of this situation, by a word spiral shell cutter or special spanner are fastened with the groove 12 on screw terminal 1, make sliding The screw of tooth can be removed easily.

One end of described groove 12 flushes with the lateral wall of described hexagon blind hole 11, the fluting direction of described groove 12 with The perforate direction of described hexagon blind hole 11 is parallel.

Preferably, each medial wall of hexagon blind hole 11 is provided with groove 12, and at least two grooves 12 Sideline, end is located on the same line.In view of actually used situation, the quantity of groove 12 is set to 6, as in figure 2 it is shown, And each groove 12 shape is identical, is distributed on the end of screw terminal 1, groove 12 is set to rectangular recess, and each groove 12 centre positions being respectively positioned on hexagon blind hole 11 medial wall, can preferably be used in combination with the general tool such as a word spiral shell cutter and No matter one word spiral shell cutter from which direction can insert；Groove 12 radially distributes with the center of hexagon blind hole 11, respectively position Two grooves 12 on two hexagon opposite side are the most corresponding, and during installation and removal, the stress ratio of screw terminal 1 is more uniform, and adds Work is the most more convenient.The groove depth of groove 12 can differ with the hole depth of hexagon blind hole 11, and preferred scheme is groove The groove depth of 12 is identical with the hole depth of hexagon blind hole 11, it is simple to processing.

Socket hexagon socket head cap screw special spanner includes that cross section is hexagonal wrench body 3, wrench body 3 and hexagon Blind hole 11 matches, and the sidewall of wrench body 3 is provided with the projection 31 matched with groove 12, the position of projection 31 and groove The position of 12 is mated completely, makes wrench body 3 can be inserted into smoothly in the hexagon blind hole 11 on screw terminal 1, and projection 31 fasten with groove 12, and the installation and removal making socket hexagon socket head cap screw are convenient.

Preferably, each sidewall of wrench body 3 is provided with projection 31, it is contemplated that actually used situation and processing feelings Condition, wrench body 3 is preferably also provided with 6 projections 31, as it is shown on figure 3, projection 31 is set to rectangular block, with the structure of groove 12 Corresponding, dismantle more laborsaving；And the shape of 6 projections 31 is identical, in the projection 31 hexagonal cross-section with wrench body 3 The heart radially distributes.The quantity of projection 31 and groove 12 and position are all one_to_one corresponding and structure is mated completely, wrench body 3 The other end identical with common spanner, make wrench body 3 can also apply to the installation and removal of common hexagon socket head cap screw, Range is more extensive.

Preferably, when the groove depth of groove 12 is identical with the hole depth of hexagon blind hole 11, one end of projection 31 is arranged On the end face of wrench body 3, and the height of projection 31 is identical with the groove depth of groove 12, the end of two relative projections 31 Sideline, portion is located on the same line, and makes wrench body 3 to put into smoothly in hexagon blind hole 11, and projection 31 and groove 12 mate completely, use more convenient.

This utility model is not limited to above-mentioned preferred forms, and anyone can obtain under enlightenment of the present utility model Go out other various forms of products, no matter but in its shape or structure, make any change, every have same as the present application or Akin technical scheme, within all falling within protection domain of the present utility model.
