Abstract

The utility model discloses a screwdriver positioning device, which comprises a grab handle, a sheathing cylinder, a ratchet gear, two stopping blocks, two springs, a positioning steel ball, a rotating ring, etc., wherein, two convex columns are arranged in the inner side of a ring plate and are capable of propping with one of the two stopping blocks when the rotating ring rotates; a side cylinder of the rotating ring is provided with right amount of concave parts and pivoted out of a containing cylinder; the positioning steel ball is arranged on one side of the containing cylinder and propped with the concave parts of the rotating ring. The rotation direction can be changed by rotating the rotating ring. Because the rotating ring is separated from the grab handle, further, an operator does not adjust the direction and touch an object in error. The utility model improves the efficiency of change of the direction of the screwdriver.

Description

The positioner of bottle opener

The utility model relates to a kind of bottle opener, refers to a kind of positioner of bottle opener especially.

The screwdriver of commonly seeing, be the structure that lever and bottle opener body is set as [integral type] the earliest, during operation, to hand lever according to holding with a firm grip, rotation, finger loosens playback, hold with a firm grip again, rotation waits constantly circulation of action, up to screwing screw or taking off screw, very inconvenient, careless manipulation also may allow the bottle opener landing, therefore, bottle opener with selectable one-way rotation develops, and their common structures are that one or two lever blocks are resisted in slippage before and after utilizing a sliding button, selecting the retaining ratchet-gear wheel of pulling, and then select the unidirectional direction of rotation of bottle opener, available holding held handle and constantly rotated (interlock bottle opener) and screw or take off screw with playback (original position is returned in reverse idle running), shortcoming is that sliding button front and back glide direction and bottle opener direction of rotation are difficult to association, the user often transfers wrong direction, and another shortcoming is sliding button and bottle opener axially parallel, when the user held the lever application of force with a firm grip, constant error touched sliding button and the unidirectional direction of rotation of bottle opener is changed.

The purpose of this utility model provides a kind of positioner of bottle opener, even but refer to rotate the hand-operated tools that a change bottle opener changes unidirectional direction of rotation.

For achieving the above object, solution of the present utility model is: the positioner of bottle opener, comprise a lever, one socket tube, one ratchet-gear wheel, two blocks and spring thereof, members such as one a location steel ball and a change, wherein lever one end is established a volumetric cylinder, articulate the socket tube of bottle opener in the volumetric cylinder, the outer affixed ratchet-gear wheel of socket tube, establish two blocks and spring thereof in the volumetric cylinder, and two blocks are in rightabout block ratchet-gear wheel by its spring ejection, change has a ring flat-plate and a side neck, the side neck of change is provided with an amount of depression and pivot is enclosed within outside the volumetric cylinder, positioning ball is located at the depression that props up change in volumetric cylinder one side, wherein two projections are established in the ring flat-plate inboard of change, and one of two projections can support when change is rotated and one of two blocks.

The positioner of above-mentioned bottle opener, its volumetric cylinder one side are provided with one and hold positioning ball to prop up the tank of change, and positioning ball has a spring.

The positioner of above-mentioned bottle opener has a dust cap, and dust cap is set on the volumetric cylinder ring flat-plate inboard with change, and is provided with two chutes that two projections for change pass respectively.

After adopting such scheme, because two projections are established in the ring flat-plate inboard, can when change is rotated, support and reach one of two blocks, the side neck of change then is provided with an amount of depression and pivot is enclosed within outside the volumetric cylinder, positioning ball is located in volumetric cylinder one side and is propped up the depression of change, borrows to rotate change and can change direction of rotation, and separates because of change and lever, and then can reach cause the operator can not transfer wrong direction, can not false touch, make bottle opener change the enhancement effect of direction.

Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.

Fig. 1 is a three-dimensional exploded view of the present utility model;

Fig. 2 is a cutaway view of the present utility model;

Fig. 3 is operation chart of the present utility model (one);

Fig. 4 is operation chart of the present utility model (two);

See also Fig. 1, Fig. 2, the utility model comprises a lever 1, one socket tube 2, one ratchet-gear wheel 3, two blocks 4,5 and

spring

41,51, one location steel ball 6, members such as one change 7 and a dust cap 8, wherein lever 1 one ends are established a volumetric cylinder 11, articulate the socket tube 2 of bottle opener (not shown) in the volumetric cylinder 11, socket tube 2 outer affixed ratchet-gear wheels 3, and, socket tube 2 is provided with groove 21 and packing ring 22 makes up other assemblies (see below and state) to cooperate a C type clasp 23, establish fin 111 in the volumetric cylinder 11 with spacing two blocks 4,5 and

spring

41,51 with retainer spring 6, and, volumetric cylinder 11 is provided with a tank 112 in addition, positioning ball 6 and spring 61 thereof are contained in the tank 112, and the outer end of positioning ball 6 can be protruded outside the opening of tank 112, and two blocks 4, the 5th, by its

spring

41,51 ejections and in rightabout block ratchet-gear wheel 3,7 of changes have a ring flat-plate 71 and a side neck 72, ring flat-plate 71 inboards are established two projections 711 and are supported and two blocks 4 when change 7 is rotated, one of 5,72 of side necks are provided with an amount of depression 721, change 7 is enclosed within outside the volumetric cylinder 11 with side neck 72 pivots, positioning ball 6 also can prop up change 7 depressions 721, to make change 7 location, other cooperation is provided with a packing ring 73 and is beneficial to combination (see below and state) in the ring flat-plate 71 of change 7, dust cap 8 is set on the volumetric cylinder 11 ring flat-plate 71 inboards with change 7, dust cap 8 is provided with two chutes 81 and supplies two projections 711 of change 7 to pass respectively, the effect of the auxiliary restriction of chute 81 tools projection 711 stroke ends; During combination, see also Fig. 1 and Fig. 2, after volumetric cylinder 11 is installed with positioning ball 6 and two blocks 4,5 and its

spring

41,51, cover dust cap 8 and packing ring 73, and two chutes, the 81 outer end correspondences that make dust cap 8 are above two blocks 4,5, and two projections 711 with change 7 pass two chutes 81 again, press the depression 721 that makes change 7 steel ball 6 that is positioned to prop up, again packing ring 22 is inserted in socket tube 2, at last C type clasp 23 is buckled into groove 21 and promptly finish combination.

During enforcement, extremely shown in Figure 4 as Fig. 2, Fig. 2 is not deflection of change 7, two projections 711 pass two chutes 81 but do not prop up arbitrary block 4,5 o'clock, lever 1, socket tube 2 and ratchet-gear wheel 3 prop up and are the one interlock, identical with the most traditional bottle opener function, and as shown in Figure 3, for change 7 deflections make a projection 711 compress a block 4 and compress spring 41, make block 4 no longer support ratchet-gear wheel 3, this moment, another block 5 still supported ratchet-gear wheel 3, then lever 1, socket tube 2 and ratchet-gear wheel 3 are the one interlock in one unidirectional (being counterclockwise shown in the figure), and during lever 1 reverse rotation, the but idle running relatively of socket tube 2 and ratchet-gear wheel 3 is the one-way operation bottle opener; As for shown in Figure 4, then be the reverse of Fig. 3, promptly another projection 711 compresses another block 5, makes block 5 no longer support ratchet-gear wheel 3, and this moment, another block 4 still supported ratchet-gear wheel 3, and the narration of the similar Fig. 3 of all the other situations is not given unnecessary details one by one.
