Abstract

The utility model discloses a box spanner's cover cartridge head belongs to spanner technical field, including the first sleeve of fixed connection in connecting rod one end, first sleeve middle part is equipped with a regular hexagon bayonet socket, first telescopic outer peripheral face is regular hexagon, box spanner's cover cartridge head still includes second sleeve, the 2nd regular hexagon bayonet socket at the second sleeve middle part, second sleeve and first sleeve sliding connection, be equipped with on first sleeve and the second sleeve and mutually support so that the spacing limit structure of second sleeve. After adopting this kind of structure, provide a box spanner's cover cartridge head, this box spanner's cover cartridge head has the nut bayonet socket of two kinds of specification sizes to realized that a box spanner can twist the nut of two kinds of specifications, has increased box spanner's function, convenient and practical.

Description

The collet head of box spanner

Technical field

This utility model belongs to spanner technical field and in particular to a kind of collet head of box spanner.

Background technology

Box spanner is widely used in life as everyday tools, and it is by multiple band hexagon sleeve heads and to join It is made up of multiple accessories such as handle, extension bars, be particularly well-suited to twist that status is very narrow and small or the bolt of depression very deep or nut.

Box spanner of the prior art, the nut bayonet socket on its hexagon sleeve head is typically all fixed size, So, will result in following deficiency:Each box spanner can only twist a kind of nut of specification, using single function, if need to twist many During the nut of kind of specification, the box spanner of multiple different specification size sizes need to be prepared, the problems such as cause inconvenient to carry.

Content of the invention

Technical problem to be solved in the utility model is to provide a kind of collet head of box spanner, this box spanner Collet head has the nut bayonet socket of two kinds of specification sizes, it is achieved thereby that box spanner can twist the nut of two kinds of specifications, Increased the function of box spanner.

For solving above-mentioned technical problem, the collet head of box spanner of the present utility model, including being fixedly connected on connecting rod First sleeve of one end, is provided with the first regular hexagon bayonet socket being adapted with hex nut in the middle part of the first sleeve;Described first set The outer peripheral face of cylinder is regular hexagon;The collet head of described box spanner also includes second sleeve, is provided with and six in the middle part of second sleeve The second regular hexagon bayonet socket that angle nut is adapted, the second regular hexagon bayonet socket runs through whole the along the axis direction of second sleeve Two sleeves, the second regular hexagon bayonet socket is socketed on the outer peripheral face of the first sleeve so that second sleeve is slided even with the first sleeve Connect;First sleeve and second sleeve are provided with and cooperate so that the spacing position limiting structure of second sleeve.

After above structure, this utility model has advantages below:Due to being provided with the first sleeve and second sleeve, the First regular hexagon bayonet socket in the middle part of one sleeve, is provided with the second regular hexagon bayonet socket, second sleeve and first set in the middle part of second sleeve Cylinder is slidably connected, and the first sleeve is provided with second sleeve and cooperates so that the spacing position limiting structure of second sleeve, During production, the first regular hexagon bayonet socket is processed into the first specification size, and the second regular hexagon bayonet socket is processed into the second specification size, So, when the nut needing to twist the first specification size, by second sleeve and the first sleeve keeping parallelism state, using first just Hexagon bayonet socket works, and when the nut needing to twist the second specification size, second sleeve part is skidded off the first sleeve, adopts the Two regular hexagon bayonet sockets work, it is achieved that box spanner can twist the nut of two kinds of specifications, increased the work(of box spanner Can, decrease box spanner carries number.

Preferably, described position limiting structure includes being located in the first sleeve lateral wall the first spacing hole/the second spacing hole, it is located at On the wall of second sleeve side and the screwed hole with the first spacing hole/the second spacing hole corresponding position and screw;Described screw spiral shell Stricture of vagina is connected to screw thread in the hole and the spacing in the hole of the first spacing hole/the second is stretched in the end of screw.So, when the end of screw is stretched into During the first spacing hole, worked using the first regular hexagon bayonet socket, when the second spacing hole is stretched in the end of screw, using second just Hexagon bayonet socket works, the working condition of convenient switching the first regular hexagon bayonet socket and the second regular hexagon bayonet socket.

Preferably, described first spacing hole, the second spacing hole are arranged along the axis direction of the first sleeve.

Preferably, described first sleeve and the axis of second sleeve are same straight line.

Preferably, it is connected for arc transition between the outer peripheral face of described first sleeve and the end face of the first sleeve.So, side Just the assembling of the first sleeve and second sleeve.

Specific embodiment

With reference to the accompanying drawings and detailed description utility model is described in more detail.

Referring to accompanying drawing 1 to shown in accompanying drawing 6, the collet head of box spanner, including being fixedly connected on the first of connecting rod 3 one end Sleeve 1, is provided with the first regular hexagon bayonet socket 1.1 being adapted with hex nut in the middle part of the first sleeve 1;It is characterized in that:Described The outer peripheral face of the first sleeve 1 is regular hexagon;The collet head of described box spanner also includes second sleeve 2, in the middle part of second sleeve 2 It is provided with the second regular hexagon bayonet socket 2.1 being adapted with hex nut, the second regular hexagon bayonet socket 2.1 is along the axle of second sleeve 2 Whole second sleeve 2 is run through in line direction, and the second regular hexagon bayonet socket 2.1 is socketed on the outer peripheral face of the first sleeve 1 so that second Sleeve 2 is slidably connected with the first sleeve 1;First sleeve 1 and second sleeve 2 are provided with and cooperate so that second sleeve 2 is spacing Position limiting structure.

The first spacing hole 4/ second spacing hole 5 that described position limiting structure includes being located on the first sleeve 1 side wall, it is located at second On sleeve 2 side wall and the screwed hole 6 with the first spacing hole 4/ second spacing hole 5 corresponding position and screw 7;Described screw 7 It is threaded in screwed hole 6 and the end of screw 7 is stretched in the first spacing hole 4/ second spacing hole 5.

Described first spacing hole 4, the second spacing hole 5 are along the axis direction setting of the first sleeve 1.

Described first sleeve 1 is same straight line with the axis of second sleeve 2.

It is connected for arc transition between the outer peripheral face of described first sleeve 1 and the end face of the first sleeve 1.

Operation principle of the present utility model is as follows:When producing, it is big that the first regular hexagon bayonet socket 1.1 is processed into the first specification Little, the second regular hexagon bayonet socket 2.1 is processed into the second specification size, when the first spacing hole 4 is stretched in the end of screw 7, adopts First regular hexagon bayonet socket 1.1 works, when the second spacing hole 5 is stretched in the end of screw 7, using the second regular hexagon bayonet socket 2.1 work, the working condition of convenient switching the first regular hexagon bayonet socket 1.1 and the second regular hexagon bayonet socket 2.1.Achieve one Box spanner can twist the nut of two kinds of specifications, increased the function of box spanner, and decrease box spanner carries number.

The above, be only the preferably feasible enforcement example of this utility model it is impossible to therefore limit to of the present utility model Interest field, for those skilled in the art, all makes with the technical solution of the utility model and technology design Other various corresponding changes all should belong within this utility model scope of the claims.
