Abstract
The utility model relates to technical field of tools, relates in particular to the ratchet spanner technical field.The utility model comprises handle housing, ratchet, needle roller, spring, jacking block, end cap, screw composition, angle between housing and ratchet is provided with a needle roller, this needle roller compresses by being positioned at spring and the jacking block that the ratchet aperture stretched out, under the effect of spring force, make needle roller be in the operating position all the time, thereby realized zero angle of revolution locking.Simultaneously, at the two-sided square sleeve driving head that all is processed with of ratchet, the matching standard collet head can be realized the forward and reverse rotation to nut.The utility model is skillfully constructed, rationally, use efficiently, convenient, laborsaving, the angle of revolution of spanner is a zero degree, can accomplish that promptly pine is promptly tight, be suitable for various workplaces and use, be particularly suitable for using, have irreplaceable advantage of other instrument and good prospects for application in narrow space.
Description
Technical field:
The utility model relates to technical field of tools, relates in particular to the ratchet spanner technical field.
Background technology:
In daily life, work, can use multiple hand tools place under repair, assembly work in large quantities, spanner promptly is one of wherein important instrument.The spanner that people use have can only single motion common wrench, but the ratchet spanner of continuous action is also arranged.Because it is efficient, easy-to-use that ratchet spanner has, make it obtain more and more widely application.
The ratchet spanner that generally uses mainly comprises housing, ratchet, ratchet at present, relies on the ratchet on the housing to lock ratchet during operation, reaches the purpose of pulling.The shortcoming of this spanner is, the angle of revolution of spanner is bigger, and operating noise is big, and the angle of revolution of handle is subjected to the influence of hook tooth distance during use, and the angle of revolution reaches 5～30 ° of ability actions, limited the scope of application of ratchet spanner, also reduced its service efficiency simultaneously.
The patent No. 01244827.3 " needle-type ratchet spanner " is though have bigger improvement and raising than common ratchet spanner, but also exist the angle of revolution not enough little, defectives such as 2～4 ° of ability of needs are moved, and the elasticity needle roller is easy to wear, distortion, aging, and operating temperature range is narrow.
Summary of the invention:
The utility model provides a kind of needle-type ratchet spanner that overcomes above-mentioned defective.It has, and career field is wide, the characteristics of high efficiency, and the angle of revolution of handle is not subjected to the influence of hook tooth distance during work, has realized that zero angle of revolution (angle of revolution arbitrarily) gets final product continuous operation, and quiet noiseless, can be operated in higher temperature.
The technical solution of the utility model is achieved in that it comprises handle housing, ratchet, needle roller, spring, jacking block, end cap, screw composition, because the utility model has adopted the angle that forms on housing and ratchet, be provided with needle roller, under the effect of the compression spring force in the ratchet aperture, no matter making needle roller is under locking or the situation of unclamping, be in the operating position all the time.When the locking direction is rotated, needle roller rotates thereby drive ratchet because the effect of frictional force is self-locking in the angle that forms between ratchet ratchet inclined-plane and inner walls, reaches the purpose of locking; When housing during to counter-rotation, because the effect of the frictional force between nut and bolt, ratchet is motionless, and housing drives needle roller and rotates in the original place, and produces idle running between housing and the ratchet, so repeatedly, reaches the degree of tightness purpose.Because needle roller is in the operating position all the time, thereby realized zero angle of revolution (angle of revolution arbitrarily) continuous operation; Owing to there has not been the dislocation between ratchet and the ratchet to move, reached quiet effect simultaneously.Because at the two-sided square sleeve driving head that all is processed with of ratchet, the matching standard collet head can be realized the forward and reverse rotation to nut.
The utility model is skillfully constructed, rationally, use efficiently, convenient, laborsaving, the angle of revolution of spanner is a zero degree, can accomplish that promptly pine is promptly tight, be suitable for various workplaces and use, be particularly suitable for using, have irreplaceable advantage of other instrument and good prospects for application in narrow space.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model, and 1 is handle housing, the 2nd among the figure, ratchet, the 3rd, needle roller, the 4th, spring, the 5th, jacking block, the 6th, end cap, the 7th, screw.
Accompanying drawing 2 is side cut-away views of Fig. 1.
The specific embodiment:
As shown in the figure, the ratchet spanner that the utility model is made up of handle housing, ratchet, needle roller, jacking block, spring, end cap, screw, in each angle that housing 1 and ratchet 2 form, be equipped with needle roller 3, be drilled with aperture on ratchet 2, spring 4 and jacking block 5 are positioned at wherein, under the effect of spring 4, jacking block 5 withstands in the middle of the needle roller 3 all the time, makes it always be in housing 1 and the angle that ratchet 2 forms, and is on the operating position all the time.Needle roller 3 adopts the higher material of intensity, and jacking block adopts copper material, both reduces friction, and is wear-resistant again.
Ratchet 2 and needle roller 3 are blocked at end face by handle housing 1 and end cap 6, prevent axial float, and handle housing 1 links together by screw 7 with end cap 6, becomes complete needle-type ratchet spanner.
Claims (2)
1, the two-sided ratchet spanner of a kind of needle-type, it comprises handle housing, ratchet, needle roller, end cap, screw, it is characterized in that, also comprise spring, jacking block, be positioned at the jacking block that the ratchet aperture is stretched out, under the effect of spring force, compress needle roller, make it be in the operating position all the time, thereby realized zero angle of revolution motion.
2, the two-sided ratchet spanner of a kind of needle-type according to claim 1, it comprises handle housing, ratchet, needle roller, spring, jacking block, end cap, screw, it is characterized in that, the two-sided square sleeve driving head that all is processed with at ratchet, the matching standard collet head can be realized the forward and reverse rotation to nut.
