Abstract

The invention discloses a combined screwdriver. The combined screwdriver comprises a handle, screwdriver rods and clamping rings. A plurality of grooves are formed in the outer wall of the handle in the axis direction of the handle. The grooves are distributed in the two ends of the handle around the outer circle of the handle, and the grooves in the two ends of the handle are arranged in a staggered manner. One ends of the screwdriver rods are hinged to the ends, close to the center of the handle, in the grooves. Sliding rails are arranged at the two ends of the outer wall of the handle in the axis direction of the handle. The number of the clamping rings is two. Sliding blocks corresponding to the sliding rails are arranged on the inner walls of the clamping rings. The clamping rings can be arranged on the handle in a sliding and sleeving manner, and the sliding blocks are clamped in the sliding rails. By means of the manner, the combined screwdriver is applicable to demounting and mounting of screws of various types and specifications, various screwdrivers are integrated, and carrying is convenient.

Description

A kind of combination screw driver

Technical field

The present invention relates to screwdriver field, particularly relate to a kind of combination screw driver.

Background technology

Screwdriver is the instrument for tightening or unscrew the screws such as head with one word, cross recess, and it comprises handle, knife bar.Because existing screw size specification is different, operating personnel need the screwdriver carrying number of different types, different size specification usually, which not only improves the purchase cost of screwdriver, and carry inconvenience.In addition, existing straight shape screwdriver, the moment of torsion of its force is little, and relatively harder when operating personnel use, efficiency is low.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of combination screw driver, dismounting and the assembling of dissimilar, different size specification screw can be applicable to, integrate multiple screws cutter, easy to carry, decrease purchase cost, and laborsaving when operating personnel use, efficiency is high; Combined screw knife structure is simple, low cost of manufacture.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of combination screw driver, comprising: handle, screwdriver rod and collar; The outer wall of described handle has some grooves along handle axis direction, and groove is distributed in the two ends of handle around handle outer ring, and the groove at handle two ends is crisscross arranged; Described screwdriver rod one end is hinged on the one end near handle center in groove; The two ends of described handle outer wall are equipped with slide rail along handle axis direction, and described collar has two, and collar inwall is provided with the slide block corresponding with slide rail, and described collar is slidably enclosed within handle, and slide block is stuck in slide rail.

Preferably, described groove and handle end face junction opening-like, when described screwdriver rod is arranged in groove, screwdriver rod stretches out in handle end face; The both ends of the surface of described handle are equipped with cylinder boss, and cylinder boss height is greater than the length that screwdriver rod stretches out in handle end face.

Preferably, the outer wall of described handle is provided with anti-skidding lines.

Preferably, described screwdriver rod comprises straight screwdriver, Phillips screwdriver, rice word screwdriver, star-like screwdriver, square head screw cutter and hex(agonal)screw cutter.

The invention has the beneficial effects as follows: the present invention can be applicable to dismounting and the assembling of dissimilar, different size specification screw, integrates multiple screws cutter, easy to carry.

Accompanying drawing explanation

Fig. 1 is the planar structure schematic diagram of a kind of combination screw driver one of the present invention preferred embodiment;

Fig. 2 is the planar structure schematic diagram of a kind of combination screw driver one of the present invention using state;

In accompanying drawing, the mark of each parts is as follows: 1, handle; 2, screwdriver rod; 3, slide rail; 4, collar.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:

A kind of combination screw driver, comprising: handle 1, screwdriver rod 2 and collar 4; The outer wall of described handle 1 has some grooves along handle 1 axis direction, groove is distributed in the two ends of handle 1 around handle 1 outer ring, and the groove at handle 1 two ends is crisscross arranged, and can strengthen the intensity of handle 1, and the contact area of handle 1 and hand can be increased, better to use; Described screwdriver rod 2 one end is hinged on the one end near handle 1 center in groove; The two ends of described handle 1 outer wall are equipped with slide rail 3 along handle 1 axis direction, described collar 4 has two, collar 4 inwall is provided with the slide block corresponding with slide rail 3, described collar 4 is slidably enclosed within handle 1, slide block is stuck in slide rail 3, when screwdriver does not use, can be set on handle 1, scatter in case screwdriver skids off under the effect being subject to external force.Described groove and handle 1 end face junction opening-like, when described screwdriver rod 2 is arranged in groove, screwdriver rod 2 stretches out in handle 1 end face; The both ends of the surface of described handle 1 are equipped with cylinder boss, and cylinder boss height is greater than the length that screwdriver rod 2 stretches out in handle 1 end face, can carry out certain protection, with anti-tamper to the cutter head on screwdriver rod 2.The outer wall of described handle 1 is provided with anti-skidding lines, with easy to use.Described screwdriver rod 2 comprises straight screwdriver, Phillips screwdriver, rice word screwdriver, star-like screwdriver, square head screw cutter and hex(agonal)screw cutter, to be adapted to different size and dissimilar screw.During use, the screwdriver rod 2 needed for selecting according to screw, slides into the center of handle 1, pushes required screwdriver rod 2 aside by the collar 4 on required screwdriver rod 2, makes required screwdriver rod 2 at an angle with handle 1, can use.

The present invention can be applicable to dismounting and the assembling of dissimilar, different size specification screw, integrates multiple screws cutter, easy to carry, decreases purchase cost, and laborsaving when operating personnel use, efficiency is high; Combined screw knife structure is simple, low cost of manufacture.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
