Description

Quick setting or loosening screwdriver

The utility model relates to a kind of screwdriver structure, particularly about a kind of removal fast or the installing screw bottle opener.

General common screwdriver or spanner, when removal or installing screw, with hand rotation screw bottle opener once, screw only rotates half-turn, so necessary constantly rotation screw bottle opener, therefore must more time and the complicated action of hand of cost, quite bother and waste time and energy, do not meet the requirement of efficient and speed.Hereat, the utility model to solve above-mentioned puzzlement, provides a kind of convenient bottle opener device that uses promptly proposing a new construction.

Main purpose of the present utility model is to provide a kind of quick setting or loosening screwdriver easy to use, broad-spectrum, makes it in the process of loading and unloading, has more the efficient height, speed is fast, and suitable labour-saving characteristic.

The purpose of this utility model is achieved in that and connects the thin of stock, thick two ends respectively form one first socket part and second socket part, first socket part connects one handle, second socket part connects a movable extension bar, be provided with scrobicular ring at the butt end that connects on the stock, supply to be provided with first steel ball ring in it, and be provided with annular recess at the thin end that connects stock, second steel ball ring then is set in the thin end that connects stock and contacts with the butt end end face, sleeve just can be socketed in and connect on the stock, it is spacing that one end of sleeve band circular hole and second steel ball ring and butt end end face form conflict, other has a collar to be socketed on the connection stock, and the movable steel ball of its inboard just can fix in annular recess, with the position of fixed muffle, and be socketed in the default instrument socket joint hole of the movable extension bar other end of second socket part, insert conversion for the bottle opener headgear.

In addition, the two ends of handle can be installed balancing weight respectively; Second socket part can be formed directly in and is screwdriver head.

Advantage of the present utility model: have and save time and the labour-saving effect, make it in the process of loading and unloading, have more efficient height, fireballing characteristic, not only easy to use, and can change arbitrarily according to different needs because of screwdriver head, purposes is also quite extensive.The utility model is more kept traditional-handwork tool primary structure, and dexterous, the easy-to-use advantage of operation is arranged.

Under illustrate in detail by the specific embodiment conjunction with figs., when the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.

Description of drawings:

Fig. 1 is a stereochemical structure exploded view of the present utility model;

Fig. 2 is a generalized section of the present utility model;

Fig. 3 is an action schematic diagram of the present utility model;

Fig. 4 is the local enlarged diagram of Fig. 3.

Main feature of the present utility model is to set up a low friction sleeve at the connection stock, as Usefulness to stock support or the application of force cooperates the weight of handle own or outer weight again, makes the utility model Only need with the suitable application of force, after the rotation of driving handle, and drive screw by the kinetic energy of rotatable handle and revolve Turn to. And the design of low friction can reduce and seizes on both sides by the arms or kinetic energy rejection that the application of force causes, increases instrument Efficient.

As shown in Figure 1, 2, it is respectively stereochemical structure exploded view of the present utility model and generalized section.As shown in the figure, in a bottle opener 10 that loads and unloads fast, appropriate location on the connection stock 12 forms the transition interface of a thickness, make it can be divided into thin end 22 and butt end 24 two ends, thin end 22 forms one first socket part 14 and second socket part 16 respectively with the tail end of butt end 24, first socket part, 14 sheathed being connected in the

handle

18,16 of second socket parts are set in the movable extension bar 20, appropriate location on the butt end 24 that connects stock 12 is provided with scrobicular ring 26, can sheathed first steel ball ring 28 in the scrobicular ring 26, and at close butt end 24 places, and the appropriate location that is positioned on the thin end 22 that connects stock 12 is provided with annular recess 30, other has 32 of second steel ball ring to be installed in the thin end 22 that connects stock 12, and contacts with an end face of butt end 24.

One end of sleeve 34 is an opening 36, the other end then is provided with circular hole 38, the slightly larger in diameter of circular hole 38 is in the diameter of the thin end 22 that connects stock 12, sleeve 34 just can be socketed on the thin end 22, one end of sleeve 34 band openings 36 is towards butt end 24, and an end face of sleeve 34 band circular holes 38 contacts with second steel ball ring 32, and because of the effect of butt end 24, make sleeve 34, it is spacing to form conflict between second steel ball ring 32 and butt end 24 end faces, and second steel ball ring 32 is between sleeve 34 and butt end 24 end faces, and sleeve 34 also coats butt end 24 and first steel ball ring 28 and second steel ball ring 32 that partly connects stock 12; Wherein, first steel ball ring 28 does not contact sleeve 34 with stock 12 butt ends 24, to reduce friction between the two.And have a collar 40 to be socketed in to connect a thin end 22 on the stock 12, and and, the movable steel ball 42 of the collar 40 inboards is fixed in this annular recess 30 because of just can blocking, connect on the stock 12 and unshift so that sleeve 34 is fixed on.

The handle 18 that is the T type, its central authorities' extension is provided with a slot 44 that conforms to first socket part 14, can be pegged graft in first socket part 14 to be fixed in the slot 44 and do not get loose, and respectively be provided with screw 46 at handle 18 two ends, other has two balancing weights 48, and its central authorities respectively are provided with stay bolt 50, utilizes this bolt 50 to lock in the screw 46 of handle 18 respectively, balancing weight 48 is fixed on the two ends of handle 18, so that a suitable weight to be provided.

One end of movable extension bar 20 is socketed in second socket part 16, and the other end then is preset with instrument socket joint hole 52, uses for the slotting usefulness of any type of screwdriver head 54 covers, and can give the conversion screwdriver head according to different demands.

Second socket part 16 can directly press and form screwdriver head, can directly use, and then do not need movable extension bar to connect other screwdriver heads this moment.

The tube-in-tube structure of the low friction of the utility model utilization is as the point of application of helping, exerting pressure, and the two ends of T type handle are equipped with pouring weight, keep higher rotation function as application of force back handle, the rotation function of handle can provide and drive the required power resources of screw rotation, when making the utility model do the single rotation to the bottle opener device, can cause bottle opener device and screw to rotate multi-turn with hand.

Shown in Fig. 3,4, be action schematic diagram of the present utility model, when using bottle opener device 10, hold on sleeve 34 with hand earlier and do not put, turning handle 18 again, and handle 18 drives the rotation that connects stock 12, and then drives the rotation of screwdriver head 54.And because of first steel ball ring 28 on the connection stock 12 in the sleeve 34 and the effect of second steel ball ring 32, connection stock 12 can be hanged down in sleeve 34 frictionally to rotate, the balancing weight 48 that cooperates handle 18 two ends again, and utilize the rotational kinetic energy of handle, make connection stock 12 rotate a few continuously, to reach the purpose of loading and unloading screw easily.

The above embodiment only is explanation technological thought of the present utility model and characteristics, its purpose makes the personage who is familiar with this skill can understand content of the present utility model and is implementing according to this, when not limiting claim of the present utility model with this, promptly the equalization of doing according to the spirit that the utility model disclosed generally changes or modifies, and must be encompassed in the claim of the present utility model.
