Description
Technical field
The present invention relates to sleeve barrel tool technical field, more particularly to a kind of multi-functional hexagonal extension bar.
Background technology
In machining, assembling and maintenance, box spanner is a more commonly used instrument, but in current a, set
The shapes and sizes of the sleeve hole of barrel spanner are all changeless, and it is only used for being adapted with its sleeve hole shape, size
Nut or bolt, and in practice, the shape of nut or bolt, size specification are various, and this just must be equipped with various shapes and big
The box spanner of small dimension, not only acquisition cost is high, must also be one by one compared when being used when topmost and select correct
Ring wrench, to actual use and operating efficiency bring serious influence.
Because the installation site of bolt is varied, thus it is higher to the length requirement of sleeve or screwdriver, and length
Big instrument is inconvenient to carry and deposited.
The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of multi-functional hexagonal extension bar.
The present invention is achieved by the following technical solutions：A kind of multi-functional hexagonal extension bar, including length are identical, are sleeved on
Gap coordinates between some six angle pipes together, two adjacent six angle pipes, the relative side wall of each six ribs pipe one of which
On, it is provided with along its length in the waist hole for all six ribs pipes to be linked together, the waist hole and is coated with spacer pin, institute
The rib thickness of pipe wall of outermost metal six stated is more than 3mm.
Further, the section at the waist hole two ends is circle, has a diameter larger than the cross-sectional width of waist hole, the spacer pin
Section be set to rectangle, the rectangle two ends are semi arch, and the length of the rectangle is in the rectangular shaped position cross-sectional width of waist hole
Between round diameter, the spacer pin wherein one end is extended on the outside of outermost six angle pipes, and is connected with knob, the rotation
Button is parallel with spacer pin.
Further, the waist hole is set close to six angle pipes wherein one end.
Further, the rib pipe of metal six is made by matrix steel.
The beneficial effects of the present invention are：Multiple six angle pipes are set in together, different extension bars can be picked out, passed through
Knob and spacer pin locking, can be used for multiple times, and structural strength is high, simple in construction, convenient use.
Brief description of the drawings
Fig. 1 is intended to for structural diagrams of the present invention；
Fig. 2 is annexation figure schematic diagram between spacer pin and outermost layer six angle pipes；
Wherein：1- six angle pipes, 2- waist holes, 3- knobs, 4- spacer pins.
Embodiment
Multifunctional connecting bar as depicted in figs. 1 and 2, a kind of multi-functional hexagonal extension bar, including length are identical, are set in together
Some six angle pipes 1, gap coordinates between two adjacent six angle pipes 1, the relative side wall of 1 one of which of each six ribs pipe
On, it is provided with along its length in the waist hole 2 for all six ribs pipes to be linked together, the waist hole and is coated with spacer pin 4,
The described wall thickness of six rib pipe of outermost metal 1 is more than 3mm, and the rib pipe 1 of metal six is made by matrix steel, with stronger
Structural strength, when using outermost six angle pipes, still with the fine life-span, the section at the two ends of waist hole 2 is circle, its
Diameter is more than the cross-sectional width of the rectangular shaped position of waist hole, and the section of the spacer pin is set to rectangle, and the rectangle two ends are half
Circular arc, facilitates it to be rotated at waist hole two ends, and the length of the rectangle is in the rectangular shaped position cross-sectional width of waist hole and round diameter
Between, facilitate it to be rotated at waist hole two ends, the spacer pin 4 wherein one end is extended on the outside of outermost six angle pipes, and even
It is connected to knob 3, the knob convenient observation parallel with spacer pin 4.The waist hole is set close to six angle pipes wherein one end, it is ensured that many
Function extension bar has longer smooth outer surface.
