Description

Box spanner

Technical field

This utility model belongs to spanner technical field, is specifically related to a kind 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 the multiple accessories such as handle, extension bar, is particularly well-suited to twist that status is the narrowest 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: in use, the box spanner of multiple different specification size size need to be prepared, to adapt to not With the nut of size, cause the problems such as inconvenient to carry.

Summary of the invention

It is adjustable that technical problem to be solved in the utility model is to provide a kind of nut bayonet socket size, such that it is able to Adapt to the box spanner of the nut of different size size.

For solving above-mentioned technical problem, box spanner of the present utility model, including collet head, described collet head includes sliding The sleeve matrix connected and regulating block；Described sleeve matrix is provided with the step groove adapted with hex nut, described step groove Extended to the middle part of sleeve matrix by the side of sleeve matrix；Chute it is provided with, the length direction of chute below described step groove Parallel with the length direction of step groove；Described regulating block includes base plate, be located on base plate and form hexagonal with the sidewall of step groove The fixture block of nut bayonet socket and the slide block being located under base plate, described slide block is positioned at chute and is connected with slide, described base plate It is positioned at step groove；Described slide block is provided with multiple spacing hole, and multiple spacing holes are arranged along the length direction of slide block, described chute Sidewall be provided with the position-limitting pin coordinated with spacing hole, position-limitting pin is flexibly connected with the sidewall of chute and position-limitting pin one End is inserted in spacing hole, and the other end is positioned at the outside of chute wall.

After using above structure, this utility model has the advantage that owing to sleeve matrix and regulating block are slidably connected group Become collet head, as such, it is possible to adjust regulating block to slip into the distance of sleeve matrix thus to adjust the size of hex nut bayonet socket big Little, such that it is able to adapt to the nut of different size size；And slide block is provided with multiple spacing hole, and the sidewall of described chute sets Have the position-limitting pin coordinated with spacing hole, when producing, can according to the standard specifications of market top nut, when each spacing hole with When position-limitting pin coordinates, the size of its hex nut bayonet socket formed changes successively, and such collet head can be suitable for multiple The nut of standard specifications.

Preferably, described position-limitting pin is flexibly connected with the sidewall of chute and refers to: on the sidewall of chute and and position-limitting pin Corresponding position is provided with perforation, and position-limitting pin is plugged in perforation, is provided with bulge loop in the middle part of position-limitting pin, and the sidewall of perforation is provided with Limited step, is arranged with spring in the middle part of position-limitting pin, spring one end pushes against with limited step, and the spring other end pushes against with bulge loop. So, on the one hand can play the effect preventing position-limitting pin from departing from perforation, on the other hand can make the more convenient insertion of position-limitting pin In spacing hole so that it is spacing firm, improve stability in use and the fixing of box spanner.

Detailed description of the invention

With detailed description of the invention, utility model is described in more detail below in conjunction with the accompanying drawings.

Seeing shown in accompanying drawing 1 to accompanying drawing 5, box spanner, including collet head, described collet head includes the sleeve being slidably connected Matrix 1 and regulating block 2；Described sleeve matrix 1 is provided with the step groove 3 adapted with hex nut, and described step groove 3 is by sleeve The side of matrix 1 extends to the middle part of sleeve matrix 1；Below described step groove 3, be provided with chute 4, the length direction of chute 4 with The length direction of step groove 3 is parallel；Described regulating block 2 includes base plate 5, be located on base plate 5 and form six with the sidewall of step groove 3 The fixture block 6 of angle nut bayonet socket 8 and the slide block 7 being located under base plate 5, described slide block 7 is positioned at chute 4 and is slidably connected with chute 4, Described base plate 5 is positioned at step groove 3；Described slide block 7 is provided with multiple spacing hole 9, and multiple spacing holes 9 are along the length side of slide block 7 To setting, the sidewall of described chute 4 is provided with the position-limitting pin 10 coordinated with spacing hole 9, position-limitting pin 10 and the sidewall of chute 4 Being flexibly connected and position-limitting pin 10 one end is inserted in spacing hole 9, the other end is positioned at the outside of chute 4 sidewall.

Described position-limitting pin 10 is flexibly connected with the sidewall of chute 4 and refers to: on the sidewall of chute 4 and right with position-limitting pin 10 Answering position to be provided with perforation 11, position-limitting pin 10 is plugged in perforation 11, is provided with bulge loop 12 in the middle part of position-limitting pin 10, perforation 11 Sidewall is provided with limited step 13, is arranged with spring 14 in the middle part of position-limitting pin 10, and spring 14 one end pushes against with limited step 13, bullet Spring 14 other end pushes against with bulge loop 12.

Described base plate 5, fixture block 6 and slide block 7 are connected as a single entity.

Operation principle of the present utility model is as follows: owing to sleeve matrix 1 and regulating block 2 are slidably connected and constitute collet head, As such, it is possible to adjustment regulating block 2 slips into the distance of sleeve matrix 1 thus adjusts the size of hex nut bayonet socket, thus can To adapt to the nut of different size size；And slide block 7 is provided with multiple spacing hole 9, the sidewall of described chute 4 is provided with and limits The position-limitting pin 10 that hole 9, position coordinates, when producing, can be according to the standard specifications of market top nut, when each spacing hole and limit When position pin 10 coordinates, the size of its hex nut bayonet socket formed changes successively, and such collet head can be suitable for multiple The nut of standard specifications；When user needs the size adjusting hex nut bayonet socket, position-limitting pin 10 is inserted difference Spacing hole 9 can change the size of hex nut bayonet socket, convenient use.

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