Abstract
The utility model discloses an auto-convolution adjustable spanner which comprises a moving head, a movable head, a spanner body, a hand screw, a screw shaft, a connecting rod, a return spring and a spanner handle, wherein the spanner body is triangular integrally; a slide groove is formed at one end of an end edge of the spanner body; the top of the other end of the end edge of the spanner body is articulated with the middle part of the movable head by a pin; a third end of the spanner body is articulated with one end of the connecting rod by a pin; an adjusting cavity is arranged on the spanner body; the screw shaft is arranged in the adjusting cavity; the hand screw is arranged on the screw shaft; the moving head is arranged in the slide groove; the bottom of the movable head is articulated with the top of the spanner handle by a pin; the connecting rod is articulated with the top of the spanner handle by a pin; and the return spring is arranged between the spanner handle and the third end of the spanner body. The auto-convolution adjustable spanner has the advantages that the auto-convolution adjustable spanner is reasonable and compact in structure, advanced in function, high in practicability, wide in adaptability, and easy to manufacture, and can perform dead point self-locking during automatic return and reverse rotation, thereby realizing functions of once chucking and continuous bolt and nut tightening.
Description
Technical field:
The utility model relates to a kind of hardware ﹠ tools, relates in particular to a kind of from circling round adjustable wrench.
Background technology:
Traditional adjustable wrench mainly comprises: comprise the fixedly main body of wrench and handle, the movable jaw, the movable jaw that match with fixing spanner place the fixedly chute of spanner by the sliding shoe of bottom, the bottom of sliding shoe is provided with diagonal pitch, the adjusting cavity fixedly is set on the spanner, regulate in the cavity and be provided with adjusting nut, adjusting nut matches with diagonal pitch.Regulate monkey wrench and the fixing spacing between the spanner by the rotation of adjusting nut, realize the chucking that will pull object or unclamp.But when near bolt or the nut other structure being arranged, after adjustable wrench need be twisted an angle, readjust position and being installed, can not realize the nut that tights a bolt continuously that once is installed, not only inefficiency but also increased working strength.
The utility model content:
The adjustable wrench that circles round certainly that the purpose of this utility model is to provide a kind of compactness rational in infrastructure, function advanced person, practical, wide adaptability, be easy to make, once be installed and can tighten continuously bolt and nut.
The utility model is implemented by following technical scheme: adjustable wrench certainly circles round, it comprises slip-on head, movable head, pull body, hand screw, screw shaft, connecting rod, back-moving spring and handle, wherein, the described body integral body of pulling is triangular in shape, be provided with chute at a described end of pulling body one end limit, other end top and described movable head middle part is hinged by pin, and it is hinged that described the 3rd end of pulling body and described connecting rod one end pass through pin; Be provided with the adjusting cavity on one's body described pulling, be provided with the described screw shaft parallel with described chute in the described adjusting cavity, be provided with described hand screw at described screw shaft; The basal sliding of described slip-on head places described chute, and described slip-on head bottom is provided with the screw thread that is meshed with described hand screw; Described movable head bottom is hinged by pin with described handle top one end; The described connecting rod other end and the described handle top other end are hinged by pin; Described movable head, described body, described connecting rod and the described handle pulled are formed four-bar linkage; Described handle and described pulling between body the 3rd end are provided with described back-moving spring.
Advantage of the present utility model: compactness rational in infrastructure, function advanced person, practical, wide adaptability, be easy to make, dead point self-locking when automatic homing and reversed turning, thereby realize once being installed the function of nut of tighting a bolt continuously, can save time on the one hand, increase work efficiency; Can alleviate labor strength on the other hand.
Description of drawings:
Fig. 1 is the structural representation of pulling body.
Fig. 2 is the structural representation of movable head.
Fig. 3 is the structural representation of pulling body.
Fig. 4 is overall structure schematic diagram of the present utility model.
Slip-on head 1, movable head 2, pull body 3, hand screw 4, screw shaft 5, connecting rod 6, back-moving spring 7, handle 8, chute 9, pin 10, regulate cavity 11.
The specific embodiment: as shown in Figures 1 to 4, from the adjustable wrench that circles round, it comprises slip-on head 1, movable head 2, pull body 3, hand screw 4, screw shaft 5, connecting rod 6, back-moving spring 7 and handle 8, wherein, it is whole triangular in shape to pull body 3, be provided with chute 9 at an end of pulling body 3 one end limits, other end top and movable head 2 middle parts are hinged by pin 10, and the 3rd end and connecting rod 6 one ends of pulling body 3 are hinged by pin 10; Be provided with and regulate cavity 11 pulling body 3, regulate being provided with the screw shaft 5 parallel with chute 9 in the cavity 11, be provided with hand screw 4 at screw shaft 5; The basal sliding of slip-on head 1 places chute 9, and slip-on head 1 bottom is provided with the screw thread that is meshed with hand screw 4; Movable head 2 bottoms and handle 8 tops one end are hinged by pin 10; Connecting rod 6 other ends and the handle 8 top other ends are hinged by pin 10; Movable head 2, pull body 3, connecting rod 6 and handle 8 is formed four-bar linkages, four-bar linkage is used for the rotation of control movable head 2, and when handle 8 backward rotation, movable head 2 can rotate in 0 °～12 ° scopes; The dead point self-locking of four-bar linkage has guaranteed that movable head 2 can not open revolution at plate during 8 forward rotation; Handle 8 and pull between body 3 the 3rd end and be provided with back-moving spring 7 is finished automatically from circling round playback action movable head 2.
During use, at first regulate hand screw 4, hand screw 4 drives slip-on head 1 and moves, and makes slip-on head 1 and movable head 2 block the nut opposite side, forward rotation handle 8, when handle 8 is limited to rotate, only need backward rotation handle 8, differently open rotation because movable head 2 is subjected to nut opposite side and diagonal distance, slip-on head 1 and movable head 2 are shifted to next nut opposite side gradually, movable head 2 is auto-closing under the effect of back-moving spring 7, continues to start working.Repeat above-mentioned action, can or unclamp nut screwing clamping; The dead point self-locking of four-bar linkage has guaranteed that movable head 2 can not open revolution at plate during 8 forward rotation.
