Description

Modularization screwdriver

Technical Field

The utility model relates to a screwdriver field is used in the maintenance, especially relates to a modularization screwdriver.

Background

The screwdriver that removable head is often not fresh at present on the market, and it has made things convenient for the bolt and the screw of answering multiple different models and size greatly, but has the inconvenient defect of carrying and losing easily of screwdriver bit, even has a fixed external member, also comparatively difficult when taking out, inefficiency. The utility model discloses a modularization screwdriver has constituteed a module with tool bit and cutter body, and each module forms an organic whole through the friction combination, with the problem that the screwdriver of fine solution removable tool bit exists.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a modularization screwdriver solves the inconvenient problem of carrying and losing easily of screwdriver bit.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model relates to a modular screwdriver, which comprises a plurality of screwdriver modules which are sequentially connected end to end, wherein each screwdriver module comprises a fixed seat and a screwdriver arranged at the lower end of the fixed seat; the fixing seat comprises a main body, wherein a first cavity is formed in the upper part of the main body, and a second cavity is formed in the lower part of the main body; the middle part of the main body is provided with a step, and the step is matched with the upper end of the main body; the screwdriver comprises a screwdriver head and a connecting piece arranged at the upper end of the screwdriver head, and the connecting piece is in interference fit with the second cavity; the first chamber is in frictional contact with the lower end of the body.

Further, the depth of the first cavity is larger than the distance from the step to the screwdriver head.

Further, the cross-sectional shapes of the first chamber, the second chamber and the connecting piece are all rhombus.

Furthermore, the fixing seat is of an integrally formed structure.

Furthermore, the specific material of fixing base is nylon.

Furthermore, the screwdriver is of an integrally formed structure.

Further, the specific material of screwdriver is alloy steel.

Compared with the prior art, the utility model discloses a beneficial technological effect:

the utility model discloses modularization screwdriver's screwdriver and fixing base interference fit form mosaic structure, have avoided the phenomenon that the screwdriver drops to appear at the in-process that uses, and then both form a module. Different screwdrivers can be combined with the fixing base at random to form modules of different types, different modules are mounted together through large friction force between nylon, and in the process of actual use, the modules of different screwdrivers are selected according to actual requirements and are directly spliced for use. In addition, the module volume that screwdriver and fixing base combination formed is greater than the volume of single screwdriver, has avoided the screwdriver to change the in-process, because the volume is less easily lost, inconvenient appearance that carries scheduling problem. In a word, this utility model modularization screwdriver not only convenient to carry, simple structure and change convenience, easily production and use.

Detailed Description

As shown in fig. 1-3, a modular screwdriver comprises a plurality of screwdriver modules connected end to end in sequence, wherein each screwdriver module comprises a fixed seat 7 and a screwdriver 8 installed at the lower end of the fixed seat 7. Fixing base 7 is the integrated into one piece structure, just the concrete material of fixing base 7 is nylon, and the frictional force of nylon material is great, can effectively prevent to drop. The screwdriver 8 is of an integrally formed structure, and the screwdriver 8 is made of alloy steel, so that maintenance and operation are facilitated.

The fixing seat 7 comprises a main body 1, a first cavity 2 is formed in the upper portion of the main body 1, a second cavity 4 is formed in the lower portion of the main body, and the size of the second cavity 4 is just used for installing a screwdriver 8. The middle part of the main body 1 is provided with a step 3, namely the whole main body 1 is of a stepped structure. Step 3 with 1 upper end of main part cooperatees, and step 3 department is the joint play that two fixing bases 7 were installed together promptly. Screwdriver 8 includes tool bit 5 and welding connecting piece 6 in the upper end of tool bit 5, connecting piece 6 with 4 interference fit of second chamber guarantee the stability of screwdriver 8 installation on fixing base 7, and can not become flexible suddenly or drop in the course of the work again. The first chamber 2 is in friction contact with the lower end of the main body 1, is not easy to fall off and is simple to replace.

The depth of the first chamber 2 is greater than the distance from the step 3 to the tip of the screwdriver 8, that is, when the two modules are mounted together, the lower part of the body 1 of the first module and the screwdriver 8 fixedly mounted therewith are completely positioned in the first chamber 2 of the second module, and the limit between the two modules is the step 3. In addition, the cross sections of the first chamber 2, the second chamber 4 and the connecting piece 6 can be in a diamond shape, a rectangular shape, an oval shape or a circular shape, and the like, and different shapes are designed according to different actual requirements.

The utility model discloses a use as follows:

firstly, the connecting piece 6 of the screwdriver 8 is in interference fit in the second chamber 4 of the fixing seat 7, so that a module is formed, the carrying by an operator is convenient, and the connecting piece is not easy to lose. Then, according to the difference of screwdriver 8 model, different modules are installed together, namely the lower part of the fixing seat 7 of the first module and the screwdriver 8 fixedly installed together with the lower part of the fixing seat 7 of the second module are installed together, and through the friction force of the fixing seat 7 per se, the two adjacent modules are not easy to fall off and are convenient to replace. And finally, replacing the modules provided with the screwdrivers 8 of different models according to actual requirements, and then working.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
