Detailed description of the invention
As Figure 1-3, a kind of described in the embodiment of the present invention can the dual-purpose ratchet spanner of bidirectional modulation, comprise wrench body 1, described wrench body 1 end is provided with Ratchet body 6, described Ratchet body 6 comprises circular groove 7, circular groove 7 inside is provided with ratchet ring 5, wrench body 1 below described circular groove 7 is provided with draw-in groove 8, draw-in groove 8 is provided with pusher dog 2, cavity 9 is provided with between circular groove 7 and draw-in groove 8, be provided with the ratchet 4 matched with ratchet ring 5 in cavity 9, between described ratchet 4 and pusher dog 2, be provided with spring 3.
As Figure 4-Figure 6, described pusher dog 2 is provided with groove 1, is provided with spring groove 11 in the middle part of groove 1, and described ratchet 4 center bottom is provided with spring card slot 12, and spring card slot 12 two side ends is respectively equipped with the groove 2 13 matched with groove 1.
As Figure 7-9, be provided with spring eye 1 in the middle part of described pusher dog 2, be provided with card article 15 bottom described ratchet 4, card article 15 is connected with spring 3.
As shown in figs. 10-12, described pusher dog 2 is provided with groove 3 16, is provided with spring eye 2 17 in groove 3 16, fixture block 18 is provided with bottom described ratchet 4, fixture block 18 is connected with spring 3 by link 19, is provided with spring fixed hole 20 bottom link 19, is fixed in spring eye 2 17 bottom spring 3.
During use, by regulating pusher dog 2 to L shelves or R shelves, realize its bidirectional modulation;
L shelves: pusher dog 2 is pulled left, because spring 3 is depressed in the spring card slot 12 of pusher dog 2, then spring 3 will move with pusher dog 2, and the groove 1 of pusher dog 2 drives groove 2 13 to stir ratchet 4, ratchet 4 being moved along rotating contrary direction with pusher dog 2, finally contacting with the cavity 9 of wrench body 1.
1) when operation element drives ratchet ring 5 to rotate counterclockwise, because ratchet ring 5 and ratchet 4 are in tooth engagement, interaction principle according to power obtains: ratchet 4 also will with ratchet ring 5 counterclockwise motion, now ratchet 4 is because contacting with the cavity 9 of wrench body 1, thus stop ratchet 4 counterclockwise motion, according to the interaction principle of power, therefore ratchet ring 5 can not rotate in the counterclockwise direction.
2) when operation element drives ratchet ring 5 to rotate clockwise, because ratchet ring 5 and ratchet 4 are in tooth engagement, interaction principle according to power obtains: ratchet 4 also will with ratchet ring 5 clockwise movement, during this position, spring 3 forces on ratchet 4, according to spring, there is collapsible performance, therefore ratchet 4 compressible spring 3 clockwise movement, when ratchet 4 departs from ratchet ring 5, thus the inhibition removed ratchet ring 5, thus ensure that ratchet ring 5 can rotate clockwise, thus make element under this position, can rotate clockwise.Because spring 3 is in compressive state, force on ratchet 4, thus make ratchet 4 constantly reset to original position, when therefore pusher dog 2 is in this position, can only makes ratchet spanner under this position, have the duty rotated clockwise.
R shelves: pusher dog 2 is pulled to the right, because spring 3 is depressed in the spring eye 1 of pusher dog 2, then spring 3 will move with pusher dog 2, and pusher dog 2 by spring eye 1 drive card article 15 stir ratchet 4, ratchet 4 is moved, the lumen contact of final and wrench body 1 along rotating contrary direction with pusher dog 2.
1) when operation element drives ratchet ring 5 to rotate clockwise, because ratchet ring 5 and ratchet 4 are in tooth engagement, interaction principle according to power obtains, ratchet 4 also will move clockwise with ratchet ring 5, now ratchet 4 is because contacting with the cavity 9 of wrench body 1, thus stop ratchet 4 to move clockwise, according to the interaction principle of power, therefore ratchet ring 5 can not rotate along clockwise direction.
2) when operation element drives ratchet ring 5 to rotate counterclockwise, because ratchet ring 5 and ratchet 4 are in tooth engagement, interaction principle according to power obtains, ratchet 4 also will with ratchet ring 5 counterclockwise movement, during this position, spring 3 forces on ratchet 4, according to spring 3, there is collapsible performance, therefore ratchet 4 compressible spring 3 counterclockwise movement, when ratchet 4 departs from ratchet ring 5, thus the inhibition removed ratchet ring 5, thus ensure that ratchet ring 5 can rotate counterclockwise, thus make element under this position, can rotate counterclockwise.Because spring 3 is in compressive state, force on ratchet 4, thus make ratchet 4 constantly reset to original position, when therefore pusher dog 2 is in this position, can only makes ratchet spanner under this position, have the duty rotated counterclockwise.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection scope of the present invention.
