A direction changing device is arranged between the socket head and the prism-shaped clipping column on the rotating rod. The utility model which has simple and rational structure and convenient use is still applicable if a nut or a bolt has the problems of limited position or excessively narrow working position.
Description
Technical field
The utility model relates to a kind of spanner, specifically is a kind of novel box spanner that is applicable to narrow operating position.
Background technology
Spanner is a kind ofly to screw or unscrew the instrument that angle screw or nut are arranged, and is one of indispensable instrument of assembly work in the machine industry, also is simultaneously the common tool in the various repair works.Difference by its structure, can be divided into open-end wrench (also being fork spanner), double offset ring spanner, combination wrenches and box spanner or the like, wherein, box spanner is made up of the collet head of handle, various different sizes, during use, collet head is placed on nut or the bolt head, rotate continuously with handle then, operating efficiency is higher, especially work as nut or bolt because the position restriction, when common wrench can not be worked, just must adopt box spanner, its often by the assembling of vehicle and agricultural machinery etc., change with repair work in adopted.But when the operating position is too narrow, can allow the angle of handle swing very little even can't swing the time, box spanner just can't use.
Summary of the invention
The utility model provides a kind of novel box spanner in order to solve the problem that existing box spanner can not be applicable to narrow operating position.
The utility model is to adopt following technical scheme to realize: novel box spanner, comprise handle and collet head, handle comprises the hollow support bar, places the dwang in the hollow support bar, dwang one end is fixed with worm gear, the hollow support boom end is fixed with the worm screw that cooperates with worm gear, and the worm screw end is provided with the rotation crank; The dwang other end is provided with the prism-shaped card post that is used for fixing collet head.During use, on nut or bolt head, the prism-shaped card post of other end and dwang end fixes, and rotates crank then continuously with the first headgear of sleeve, makes dwang drive collet head through worm gear, worm gear and rotates, and then realize screwing and unscrew nuts and bolt.
Be provided with the changed course device between the prism-shaped card post on collet head and the dwang; Make collet head vertical, bolt, the nut of specific position are operated with convenient with dwang.
Described changed course device comprises the hollow stationary magazine creel that is fixed in the hollow support boom end, place in the hollow stationary magazine creel with the fixing driving bevel gear of dwang end prism-shaped card post, the hollow stationary magazine creel is provided with the driven bevel pinion that cooperates with driving bevel gear, and driven bevel pinion is provided with the prism-shaped card post of fixed muffle head.
Described changed course device comprises the housing that is fixed in the hollow support boom end, places the worm screw in the housing, the worm gear that cooperates with worm screw, the prism-shaped card post of worm screw end and dwang end fixes, and worm gear end face central authorities are provided with the prism-shaped card post that is used for fixing collet head.The changed course device of above-mentioned two kinds of structures alters course collet head through the fit structure of bevel gear group or worm and gear, makes it vertical with dwang, and the rotation of dwang is passed to collet head.
Compared with prior art, the utility model becomes crank rotation/swing with rational handle arrangement with the direct swing of handle, owing to be not that handle is directly swung, too narrow for the operating position, can allow the situation that the angle of handle swing is very little even can't swing, box spanner still can use; And between the prism-shaped card post on collet head and the dwang, the changed course device is set, and make collet head vertical with dwang, can operate bolt, the nut of specific position easily.
The utility model is simple and reasonable for structure, and is easy to use, when problems such as the restriction of nut or bolt location, operating position be too narrow, stands good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the another kind of structural representation of the utility model changed course device;
Among the figure: the 1-collet head; 2-hollow support bar; The 3-dwang; The 4-worm gear; The 5-worm screw; 6-rotates crank; 7-prism-shaped card post; 8-hollow stationary magazine creel; The 9-driving bevel gear; The 10-driven bevel pinion; 11-prism-shaped card post; The 12-housing; The 13-worm screw; The 14-worm gear; 15-prism-shaped card post.
The specific embodiment
Novel box spanner, comprise handle and collet head 1, handle comprises hollow support bar 2, places the dwang 3 in the hollow support bar 2, and dwang 3 one ends are fixed with worm gear 4, hollow support bar 2 ends are fixed with the worm screw 5 that cooperates with worm gear 4, and worm screw 5 ends are provided with rotates crank 6; Dwang 3 other ends are provided with the prism-shaped card post 7 that is used for fixing collet head 1.
Be provided with the changed course device between the prism-shaped card post 7 on collet head 1 and the dwang 3.
Described changed course device comprises the hollow stationary magazine creel 8 that is fixed in hollow support bar 2 ends, place in the hollow stationary magazine creel 8 with the fixing driving bevel gear 9 of dwang 3 end prism-shaped card posts 7, hollow stationary magazine creel 8 is provided with the driven bevel pinion 10 that cooperates with driving bevel gear 9, and driven bevel pinion 10 is provided with the prism-shaped card post 11 of fixed muffle head 1.
Described changed course device comprises the housing 12 that is fixed in hollow support bar 2 ends, places the worm screw 13 in the housing 12, the worm gear 14 that cooperates with worm screw 13, the prism-shaped card post 7 of worm screw 14 ends and dwang 3 ends fixes, and worm gear 14 end face central authorities are provided with the prism-shaped card post 15 that is used for fixing collet head 1.
During concrete enforcement, the end of hollow support bar 2 fixing changed course devices is a prism-shaped, can be triangular column, quadrangular shape or the like, by of the relative variation of changed course device with fixed position, hollow support bar prism-shaped end, can change collet head and the deviation angle that rotates crank, make the rotation crank be in the state that the user is suitable for rotation of being convenient to always, can be owing to the position of nut, bolt, the use that the angle of inclination influences box spanner described in the utility model; In addition, big or the residing operating position of crank is narrower when the size of screw or nut, when the angle that crank can be swung is very little,, rotate the crank that crank 6 rotates for one-way clutch in order to tighten and unclamp screw or nut, for example: the ratchet crank, crank clockwise rotates when promptly tightening, and when the crank backward rotation, ratchet skids off in the inclined-plane of hook tooth, worm screw, worm gear, dwang do not rotate, thereby screw or nut can not followed counter-rotating.Unclamp screw or nut if desired, only need upset that the rotation crank is installed and get final product towards counterclockwise rotating.The structure of the crank that described one-way clutch rotates has multiple, and is known configurations, and those skilled in the art is easy to realize.
The prism-shaped card post of the utility model dwang end fixedly tail end is fixed with the screwdriver of the sleeve that cooperates with prism-shaped card post, and then can be used for the turn of the screw nail; Even can be on the prism-shaped card post of dwang end fixed drill bit, screw thread hitch, make the utility model as small-sized drilling equipment, cutting thread device.
