Abstract
The utility model relates to a manual mechanical tool which is especially used for screwing or loosening nuts. The existing socket spanners only screw nuts with small sizes. A bolt head is continuously exposed following the screwing of a nut, a nut can not be screwed when the bolt head pushes a socket spanner, and the nut can not be tightly screwed. The utility model has a small application range. The utility model adopts a connecting piece and a ratchet wheel as a whole, the structure of a through hole is arranged along the central line, the bolt head can extend into the through hole conveniently, the nut can be screwed into any position, or the nut in any position can exit, and the utility model has wide application range.
Description
Technical field: the utility model relates to a kind of manual machine tool, particularly to the precession of nut or unclamp.
Background technology: existing box spanner, can only be to nut precession reduced size, along with the nut precession, bolt head constantly exposes, and when bolt head withstood box spanner, nut promptly can't precession, can't reach the purpose that screws nut, and its scope of application is less.
Summary of the invention: the purpose of this utility model provides the young spanner of a kind of cannulated sleeve, and it can screw into the optional position to nut as required, and it is little to have solved the size of box spanner precession in the past, can not adapt to big apart from precession or situation about withdrawing from.
The utility model comprises handle (11), place the ratchet (3) of handle front end ratchet shell (2), be installed on and stir ratchet (3) shift fork (7) in the handle (11), one end is connected with ratchet (3), the connector (5) that the other end and sleeve (6) upper end is slidingly matched, the utility model special character are that connector (5) and ratchet (3) are through hole along the axle neutral conductor.
The utility model special character is that also connector (5) and ratchet (3) are for whole.
The utility model special character is that also the be slidingly matched cross section of portion of the lower end of connector (5) and sleeve (6) upper end is a regular hexagon.
The utility model special character also be shift fork (7) be furnished with about two pusher dogs, be respectively left pusher dog (12), right pusher dog (13).
The utility model can screw into nut any position, or any position nut is withdrawed from, and it is not subjected to the bolt length restriction, can adapt to tightening or unclamping of all nuts.
Description of drawings: Fig. 1 is the utility model structural representation
Fig. 2 is an internal organs view of the present utility model
Fig. 3 is the utility model connector bottom and upper cartridge cooperation place cross sectional representation
Fig. 4 is the utility model ratchet and shift fork structural representation
The specific embodiment: ratchet (3), connector (5) are overall structure, and along shaft centre line is through hole, make things convenient for bolt head to stretch out, be placed on handle (11) in the whole ratchet shell (2), ratchet (3) can rotate in ratchet shell (2), trim ring (1) covers ratchet (3) top, is welded on the ratchet shell (2).Connector (5) is the regular hexagon structure with sleeve (6) place of being slidingly matched, top cross section, and is fastening by pin (4), prevents sleeve (6) landing.Screw as required or unclamp the nut size, choose corresponding sleeve (6), make that hole size and nut are complementary in sleeve (6) bottom, sleeve (6) can dispose many, so " son " word is arranged in the utility model title, and expression is furnished with a lot of sleeves (6).
When needs precession nut, advance the left pusher dog of shift fork (7) (12), withstand ratchet (3), compression spring (10) promotes traveller (9) and presses to shift fork (7), makes the left pusher dog of shift fork (7) (12) press closer ratchet (3).Swing handle (11) promptly drives ratchet (3) and rotates in the same way clockwise, drives sleeve (6) by connector (5) again and rotates in the same way, reaches the purpose of precession nut.Along with the nut precession, bolt head constantly passes sleeve (6) centre bore, puts in connector (5), ratchet (3) central through hole, passes trim ring (1) centre bore at last, stretches out the spanner outside, also is that bolt head is unblocked in nut precession process, and nothing limits.When advancing the right pusher dog of shift fork (7) (13) to withstand ratchet (3), oppositely pull handle, can realize withdrawing from of nut.Therefore the utility model precession or unclamp any position nut is not freely limited by bolt head length.
Claims (4)
1, the young spanner of a kind of cannulated sleeve, comprise handle (11), place the ratchet (3) of handle (11) front end ratchet shell (2), be installed on and stir ratchet (3) shift fork (7) in the handle (11), one end is connected with ratchet (3), the connector (5) that the other end and sleeve (6) upper end is slidingly matched, its feature just are that connector (5) and ratchet (3) are through hole along the axle neutral conductor.
