The utility model discloses technical scheme's advantage mainly embodies: the length of outer hexagonal body is less than or equal to 12 of special screwdriver head of deep hole's overall length to the length of outer hexagonal body also obtains optimizing with the width size, under the prerequisite of guaranteeing its intensity, has improved the working range of screwdriver head.
Description
Technical field
The utility model relates to a kind of hardware & tools, especially a kind of accessory of screw rotating tool.
Background technology
No matter be plant equipment, household electrical appliance, or daily living article, be all combine as a whole by multiple parts usually.For the combination of multiple parts, the most frequently used connected mode is screw or bolt arrangement.Adopting screw or bolt to connect the most basic instrument is exactly screw rotating tool, i.e. screwdriver and the screwdriver bit that coordinates with it.Screwdriver is a kind ofly used for twisting screw or bolt with the instrument forcing it in place, generally includes a handle body and be positioned at its word foremost or cross working head.Screwdriver comprises various ways, and modal one is Assembled screwdriver, and namely the handle body front end of screwdriver is an interior hexagonal, replaceable multiple screwdriver bit in it, and in order to use difformity, the screw-driving of different size only uses.But there is its screw hole in some special parts to be super-long hole at present, cause screwdriver bit can not deeply tighten screw or bolt, hamper completing of work.
Summary of the invention
The purpose of this utility model is exactly to solve the above-mentioned problems in the prior art, provides a kind of deep hole full dog point socket set screwdriver bit of structure optimization.
The purpose of this utility model is achieved through the following technical solutions:
A kind of deep hole full dog point socket set screwdriver bit, comprise outer-hexagonal body and be positioned at the cylindrical posts of its front end, this stock foremost for having the working head matched with screw end, the length of described outer-hexagonal body is less than or equal to 1/2 of the overall length of described deep hole full dog point socket set screwdriver bit.
Preferably, described working head is a word, cross or plum blossom-shaped working head.
Preferably, the length of described outer-hexagonal body equals the twice of its width.
Preferably, the diameter of described cylindrical posts is less than or equal to 1/2 of the width of described outer-hexagonal body, is provided with rounding off portion between described cylindrical posts and described outer-hexagonal body.
Preferably, the overall length of described deep hole full dog point socket set screwdriver bit is not more than 28mm.
Preferably, described deep hole full dog point socket set screwdriver bit is obtained by alloy tool steel, spring steel.
The advantage of technical solutions of the utility model is mainly reflected in: the length of outer-hexagonal body is less than or equal to 1/2 of the overall length of described deep hole full dog point socket set screwdriver bit, and length and the width dimensions of outer-hexagonal body are also optimized, under the prerequisite ensureing its intensity, improve the working range of screwdriver bit.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
The purpose of this utility model, advantage and disadvantage, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below.These embodiments are only the prominent examples of application technical solutions of the utility model, allly take equivalent replacement or equivalent transformation and the technical scheme that formed, all drop within the claimed scope of the utility model.
The utility model discloses a kind of deep hole full dog point socket set screwdriver bit, comprise outer-hexagonal body and be positioned at the cylindrical posts of its front end, this stock be a word or cross or plum blossom-shaped or other Common Shape working heads foremost, the length of described outer-hexagonal body is less than or equal to 1/2 of the overall length of described deep hole full dog point socket set screwdriver bit.
Find after test of many times: when the overall length of deep hole full dog point socket set screwdriver bit is not more than 28mm, the length L1 of described outer-hexagonal body is substantially equal to 1/2 of the overall length L of described deep hole full dog point socket set screwdriver bit, and the length L1 of described outer-hexagonal body equals the twice of its width D, the diameter of described cylindrical posts equals 1/2 of the width D of described outer-hexagonal body, rounding off portion is provided with between described cylindrical posts and described outer-hexagonal body, screwdriver bit intensity under this structure is best, can transmit maximum moment of torsion and indeformable.Certainly, described deep hole full dog point socket set screwdriver bit is preferably and is obtained by the high strength steel such as alloy tool steel, spring steel.
The advantage of technical solutions of the utility model is mainly reflected in: the length of outer-hexagonal body is less than or equal to 1/2 of the overall length of described deep hole full dog point socket set screwdriver bit, and length and the width dimensions of outer-hexagonal body are also optimized, under the prerequisite ensureing its intensity, improve the working range of screwdriver bit.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
