Description

The slide rail type working head stores module screwdriver device

The utility model relates to screwdriver, refers in particular to a kind of slide rail type and has the screwdriver device that work stores the replaceable working head of module.

The screwdriver of existing replaceable working head still has following shortcoming: 1, can store working head and be provided with shank, be subjected to spatial constraints, and limited amount, the performance effect is little; 2. when changing working head, the job in hand of must stopping, very inconvenient.

The purpose of this utility model provide a kind of working head store many, change again the module of slide rail type working head storage easily screwdriver device.

The purpose of this utility model is achieved in that the slide rail type working head stores module screwdriver device, it comprises bearing body, cabin formula module and holds bar, it is characterized in that: this bearing body front end is provided with one for the bar that holds of accepting replaceable working head, its rear end forms the apotheca of the hollow of a holding cabin type module, one surface, bearing body rear end is provided with guide-track groove, and this cabin formula module is provided with the guide rail that is meshed with guide-track groove, and cabin formula module is provided with the hole seat that bears working head in addition.

Above-mentioned design, cabin formula module can be established more than one, and holding bar is the detachable structure, and the hole seat can be established a plurality of, and it is convenient, effective that the mat guide rail is opened replacing.

Below by drawings and Examples the utility model is described further again.

Fig. 1 the utility model embodiment stereo appearance figure;

Fig. 2 the utility model embodiment decomposition appearance figure;

Fig. 3 the utility model cabin formula module is cross-sectional schematic partly;

Fig. 4 is Figure 1A-A ' cross-sectional schematic;

Fig. 5 is Figure 1B-B ' cross-sectional schematic;

Fig. 6 the utility model user mode schematic diagram;

Another specific embodiment schematic diagram of Fig. 7 the utility model;

The another specific embodiment schematic diagram of Fig. 8 the utility model.

As Fig. 1, bearing body 2 front ends are provided with one and hold bar 1, working head is loaded on the front end that holds bar 1, cabin formula module 3 is provided with push button bar 34 with guide rail 221 junctions, be provided with 3 of cabin formula modules that push away group button bar 34 and be incorporated into inside, bearing body 2 rear end, and with the guide rail 342 that is opened in push button bar 34 front ends be opened in bearing body 2 rear ends, be meshed with push button bar 34 corresponding guide-track grooves 22, cabin formula module 3 can be contained in inside, bearing body 2 rear end, is provided with joint portion 35 in the bearing body 2.Push button bar 34 surperficial front ends are established male part 341, can conveniently release, draw in cabin formula module 3 and change working head.

As Fig. 2, bearing body 2 rear ends form the apotheca 21 of a hollow, the side offers guide-track groove 22, periphery and guide rail 342 relative edges offer guide rail 221, with be opened in cabin formula module rear side on vertically the guide rail 342 of push button bar 34 front ends be meshed, push button bar 34 length are greater than cabin formula module 3 length, to guarantee engagement; Offer on formula module 3 longitudinal sections, cabin a plurality of and vertical push button bar 34 also promptly with the perpendicular hole seat 32 of bearing body 2 to put working head 4, apotheca 21 terminal inboards are provided with flange 23, can block cabin formula module, prevent to skid off.

As Fig. 3, the diapire of hole seat 32 and sidewall have at least a part to form opening so that take.

As Fig. 4, push button bar 34 is sandwiched in guide-track groove 22, so that cabin formula module 3 is incorporated in the bearing body 2.

As Fig. 5, hole seat 32 is to put working head 4 in apotheca 21, and flange 23 makes unlikely skidding off, and firmly then can pull out.

As Fig. 6, when pushing away male part 341, just cabin formula module 3 can skid off along guide rail 221 with finger.

As Fig. 7, bearing body 5 outer rims are circular, inner edge is a polygonal, apotheca 51 is established cabin formula module 6, its push button bar 62 is parallel to hole seat 61, the hole seat 61 of placing working head 7 also promptly parallels with cabin formula module 6 with bearing body 5, bearing body 5 sides offer guide-track groove 52 and guide rail 521 and with push button bar 62 on the male part 61 of establishing and guide rail 621 corresponding and mesh.

As Fig. 8, bearing body 2A front end to hold bar 1A be folding structure and place in the formula module 3A of cabin.

Therefore the utility model nationality slide rail is opened, and is quick and convenient.
