Description

Screwdriver with threaded holder

The utility model system provides a kind of new and improved structure that is provided with the turnbuckle bottle opener, especially refer to a kind of convertible its screwdriver head that has, and conversion with screwdriver head, the also conversion thereupon of turnbuckle tube head on it, with so that same bottle opener is removed can be by the conversion of screwdriver head, and the variant screwdriver head of different shape, size with multiple difference and makes outside its function that has specific bottle opener respectively, but and has a merit able one of clamping screw terminal.

By tool turnbuckle bottle opener can be disclosed on the market at present, (this turnbuckle system is used to locking or pine when unloading screw, can clamp screw terminal, and make it when work, need not to help the screw person with finger in addition), and in the design of initial stage institute's tool, its turnbuckle system is fixed on the bottle opener, and can't take out individually, yet well known person, because be the scope of application and the function of cooperating thing and the special tool of various screw, so the bottle opener that it used, also must be with the pattern of the various differences of getting everything ready, yet thus, for the user, then, promptly must prepare a kind of bottle opener of tool turnbuckle for carrying out a kind of function thereupon, precisely because do not see that it just on then not using, and in preparing on this all types of hand-held tools, one of promptly must spend greatly the pen expenditure, so and do not conform to practicality.

And the tool turnbuckle bottle opener of later stage finding, because the inconvenience of initial stage designer institute tool, therefore be that the turnbuckle on the bottle opener is made as can the person of taking off, that is this turnbuckle system can be sheathed on the bottle opener of each tool difference in functionality at any time, yet this type turnbuckle is tool one major defect still: when being arranged at this turnbuckle on the bottle opener owing to desire, must cooperate the bottle opener that is provided with specific snap fastener, therefore, for the envoy, still need purchase the various bottle opener that this is equipped with this snap fastener separately, be with regard on the economic benefit, this type of screw is placed in does not have special practical effect in the enforcement.

The purpose of this utility model is to provide a kind of only need purchase a bottle opener, can be applicable to the working condition of various differences respectively, and the turnbuckle on it also can do any conversion thereupon, to be adapted to various replaceable screwdriver heads.

Tool turnbuckle bottle opener of the present utility model, lie in one of bottle opener handle end, be fixed with a connecting rod, it is big collet head than its shaft that the top of this connecting rod is provided with an external diameter, outside this collet head on the side end face, be provided with the shrinkage pool of a regular polygon, and but the screwdriver head of the multiple different size of blocking therebetween, and enclose outside this connecting rod and be arranged with a hollow loop bar, end is provided with the stop section that an internal diameter slightly dwindles under this hollow stem, and between collet head and stop section, then be provided with a spring, receive in the handle end to promote the hollow loop bar, the top outer rim of hollow loop bar is provided with thread, but and spiral shell is established a casing head thereon, this can be arranged on the hollow loop bar or the casing head that is unloaded at any time, look the different of the set notch size that is connected of its top and lateral margin, and have plurality of specifications, use and to cooperate the multiple screwdriver head that is equipped in the link rod sleeve head end.

Now conjunction with figs. to be describing its primary structure of the utility model in detail,

Fig. 1 is the stereo appearance figure of the utility model.

Fig. 2 is the three-dimensional exploded view of the utility model.

Fig. 3 is the cutaway view of the utility model.

Fig. 4 is the cutaway view of the utility model embodiment.

Please join shown in Figure 2, the utility model mainly includes a handle 1, a hollow sleeve 2, a spring 3, a connecting rod 4, most screwdriver heads 5 and pullover 6, wherein the shaft 42 of connecting rod 4 is to be placed through among the

spring

3, and 2 of hollow sleeves are placed on outside the spring 3, and because the length that the length of connecting rod 4 is detested bar 2 greater than hollow, thus connecting rod 4 its be provided with end under the protruding wing 41, can be exposed to outside the hollow sleeve 2, and be wedged in handle 1 inside (as shown in Figure 3), to form the blocking state.

Aforementioned connecting rod 4 its front ends are provided with a collet head 43 that external diameter is bigger, and end under the hollow sleeve 2 be provided with the less stop section of an internal diameter 21, and spring 3 is located at just between casing head 43 and the stop section 21, therefore by the power of spring 3, hollow sleeve 2 will inwardly be received.Please refer to Fig. 2, shown in Figure 3, collet head 43 its front end face central authorities on connecting rod 4 tops are provided with a regular polygon shrinkage pool 44, and can be in this shrinkage pool 44 each tool function of holding, and the screwdriver head 5 that kenel has nothing in common with each other, at any time the screwdriver head of being changed by this visual need of work 5, can give the function of its variation of the utility model, be one of its primary structure feature of the utility model person.

Its creative feature again of the utility model, tie up in hollow sleeve 2 its top outer rims and be provided with thread 22, and but spiral shell is established a casing head 6 thereon, the side of this casing head 6 respectively is provided with a breach that is connected 61 with the top, 62, setting by this casing head 6, can be in using the period of the day from 11 p.m. to 1 a.m of the present utility model, can be earlier with hollow sleeve 6 to extrapolation, as shown in Figure 4, then that the desire lock is fixing or unload screw 7 head ends 71, breach 61 via casing head 6 lateral margins enters in the casing head 6, and since the width of casing head 6 top breach 62 greater than the diameter of screw shaft 72, and less than footpath outside the screw terminal 71, therefore by the power of spring, can set screw terminal 71 between screwdriver head 5 and casing head 6 top inner edges, outside screw shaft 72 then protrudes from via casing head 6 top breach 62.

And its casing head 6 is made as movable and displacer at any time in the utility model, main system is because the screwdriver head 5 on the sleeve 43 of its connecting rod 4 ends, system is displacer at any time, yet screwdriver head 5 is in order to be embedded at the interior screwdriver head fastening end 51 of collet head shrinkage pool 44, its external diameter size no doubt can be made as permanent identical with footpath within the shrinkage pool 44 so that be equipped in person in the shrinkage pool 44, yet person known to the crowd, precisely because screwdriver head 5 not many variations of shape of its working end 52, and the size that the screw that uses 7 is looked in the footpath outside this working end 51, and also have size not, its sleeve pipe 6 is the person that is made as the movable in the utility model, and the breach on it 61,62 sizes also have the size of difference thereupon, the conversion person thereupon with the change that can cooperate screwdriver head 6.

By above-mentioned structure set-up mode, can make the screwdriver head that can freely change on it 5 and casing head 6, and make the utility model possess the specific function of the special tool of all various bottle openers, but and all can have an effect of clamping screw terminal 71; And user's bottle opener of the present utility model of only need purchasing can possess the common function of multiple bottle opener, therefore except that can greatly reducing its instrument cost, still have easy to use, and advantage such as be easy to carry.
