Abstract

A hexagonal wrench, one end of the wrench forms the bulb, and form a ring neck portion in the inner peripheral surface of the bulb of the adjacent bulb, wherein the periphery of bulb is set up and formed a hexagonal surface annularly, and there is a containing groove inward in more than one of the hexagonal surfaces, the notch of the containing groove is slightly smaller than the body of the groove, and there are a spring and a small steel ball whose inside is pushed by the spring and outside exposes the containing groove in order from inside to outside; the utility model discloses but utilize slick and sly just elasticity propelling movement's structure in little steel ball surface, when utilizing the hexagonal hole of bulb portion to insert the spiral shell latch fitting to one side, have the efficiency of convenient business turn over to because little steel ball can fill the space of hexagonal hole because of using wearing and tearing, make the utility model discloses can more laborsaving and difficult messenger hexagonal hole wearing and tearing when rotating.

Description

Die nut

Technical field

The utility model relates to a kind of hand-operated tools, relates in particular to a kind of die nut that filling space is constructed that is provided with in end formation ball head and in this place.

Background technology

Existing die nut, as No. 1236952 " die nut on-slip apparatus structure () " novel patent case of TaiWan, China letters patent book number, in order to prevent that die nut from damaging because of slip causes hexagon ring when the hexagon ring that inserts spiral lock rotates, therefore the end in wrench body radially is provided with a profile groove, and support part by side face screw lock one spiral shell and pass profile groove, support part profile groove is enlarged by adjusting spiral shell, the side face that makes wrench body one end enlarges and can be close to hexagon ring and reach skid-resistant effect.

Other has a kind of die nut, the one end forms the ball head that a side face is a hex surface, and lateral circle surface forms the structure of a ring neck in adjoining ball head, volume by the neck deflation, make this kind die nut to stretch into the hexagon ring of spiral lock and cooperate the rotation spiral lock with ball head is oblique, yet the hexagon ring of spiral lock often enlarges because of wearing and tearing, and ball head is except being not easy oblique involutory being inserted in the hexagon ring, plug the situation that also is difficult for closely and easily causing slip, make hexagon ring produce wearing and tearing, and aforesaid die nut on-slip apparatus structure supports part owing to also need adjust spiral shell before using, and only can enlarge whole area, therefore still can't solve the problem that ball head cooperates with hexagon ring, the method for must looking in addition is to improve the shortcoming that aforementioned ball head uses.

The utility model content

Technical problem underlying to be solved in the utility model is, there is the oblique involutory problem that plugs and cause slip easily that is not easy in order to overcome existing die nut ball head, the utility model provides a kind of novel die nut, to be provided with the technological means of filling space structure at ball head, to reach and rotate the more laborsaving and difficult advantage that makes hexagon ring generation wearing and tearing because of slip when using.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of die nut, one end of this spanner forms ball head, and in the interior lateral circle surface formation one ring neck of adjoining this ball head, the peripheral ring of this ball head is established and is formed a hex surface, it is characterized in that: this hex surface inwardly is provided with a storage tank more than one of them, the notch of this storage tank is slightly less than the groove body, and is provided with a spring from inside to outside in regular turn and an inboard is subjected to the spring push and the outside to expose the little steel ball of storage tank in storage tank.

Aforesaid die nut, wherein spanner is L shaped die nut, and only is provided with a storage tank in the wherein one side of described hex surface.

Aforesaid die nut, wherein the notch of storage tank is that diameter is between the groove body of each storage tank and the ball bead between the notch for circular and described little steel ball.

The utility model is the hexagon ring of going into spiral lock with the ball head oblique cutting when using, because little steel ball surface is slick and sly and have elasticity, when going into hexagon ring, the ball head oblique cutting can slide and convenient turnover, and after ball head enters hexagon ring, the little steel ball that can advance and retreat can be filled up hexagon ring and not align the space that produces because of the space of using wearing and tearing reaches owing to plugging, can be adjacent to the hexagon ring wall when the utility model is rotated, rotate the more laborsaving and difficult situation that makes hexagon ring generation wearing and tearing because of slip when using.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic perspective view of the utility model preferred embodiment.

Fig. 2 is the profile that the utility model preferred embodiment is inserted in hexagon ring.

Fig. 3 is the section action diagram that hexagon ring is inserted in the utility model preferred embodiment.

Fig. 4 is the enforcement schematic diagram of the utility model preferred embodiment.

The number in the figure explanation:

10 spanners, 11 ball heads

12 necks, 13 hex surfaces

14 storage tanks, 15 springs

16 little steel ball 20 spiral locks

21 hexagon rings

The specific embodiment

The utility model is a kind of die nut, see also Fig. 1 to preferred embodiment shown in Figure 3, this spanner 10 is L-shape spanners of hexagonal, it forms slightly rounded ball head 11 in long one section outer end, and form the less neck of a ring diameter 12 in the side face of adjoining ball head 11 inboards, wherein the peripheral ring of ball head 11 is established and is formed a hex surface 13, and inwardly vertically be concaved with the storage tank 14 of a circle in hex surface 13 one side wherein, the notch of this storage tank 14 is for circle and be slightly less than the groove body, and being provided with a spring 15 from inside to outside in regular turn and an inboard is subjected to spring 15 pushing tows and an outside part to expose the little steel ball 16 of storage tank 14, these little steel ball 16 diameters are between the groove body of storage tank 14 and the ball bead between the notch.

The utility model is except that one of them is provided with the storage tank 14 in hex surface 13 as above-mentioned preferred embodiment, also can all be provided with storage tank 14 in hex surface 13 wherein adjacent two sides or three faces, in each storage tank 14, be provided with spring 15 and be subjected to spring 15 pushing and pressing and an end exposes the little steel ball 16 of storage tank 14, and spanner 10 also can be T shape spanner, and the utility model is not limited at this.

When the utility model is implemented, with the preferred embodiment is example, and see also Fig. 2 to Fig. 4, be to utilize little steel ball 16 structure that the surface is slick and sly and but elasticity advances, when going into the hexagon ring 21 of spiral lock 20 with ball head 11 oblique cuttings, the turnover of can sliding easily, during use because little steel ball 16 can be filled up hexagon ring 21 because of using wearing and tearing or not aligning the space that is produced because of the hex surface 13 of ball head 11, make the utility model insert the inwall that can closely be posted by hexagon ring 21 when hexagon rings 21 rotate, make when rotating more laborsaving and be difficult for making hexagon ring 21 wearing and tearing with ball head 11.
