Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As Figure 1-5, the ratchet spanner of the utility model embodiment, comprise head 1, and the handle 2 to be connected with head, head 1 be provided with one run through its thickness direction, stamping-out out and the through hole 11 of accommodating gear 3 and brake assemblies, the two ends of through hole 11, namely mounting groove 12 and lower mounting groove 13 is respectively equipped with above and below, accommodating upper stop piece 6 and lower stop piece 7 respectively, this upper stop piece 6 and lower stop piece 7 seal this through hole 11 from upper and lower both sides respectively, make to form holding space for holding gear member 3 and a brake assemblies in through hole.
Expose from upper stop piece 6 and the corresponding hole of lower stop piece 7 respectively above and below described gear member 3, and wherein one end has attaching nut when connector 32 moves for spanner.The side face of this gear member 3 is face of gear, is positioned at through hole 11, and brake assemblies is positioned at the side of described through hole 11 near handle 2.Brake assemblies comprises left and right two panels brake(-holder) block 41,42, and the middle controll block 43 between left and right brake(-holder) block 41,42, respectively has a spring 51,52 between this left and right brake(-holder) block 41,42 and side of through hole 11.The left and right sides of through hole 11, there is the left and right accommodating position 111,112 of accommodating left and right control strip 41,42 respectively, the middle part at left and right accommodating position 111,112 is that circular arc is protruding outside to through hole 11, and this circular arc middle part is used for the spring 51,52 between accommodating left and right control strip 41,42 and through hole 11.Through hole 11 is respectively equipped with two detents 15 one end for accommodating left and right brake(-holder) block 41,42 near the side of handle 2, the other end of this left and right brake(-holder) block 41,42 extends towards described gear member 3 and matches with the face of gear on gear member 3 and controls.
Middle controll block 43 is when centre position, as shown in Figure 3, left and right brake(-holder) block 41,42 is because the effect of spring 51,52 is away from the left and right accommodating position 111,112 of through hole 11, therefore, left and right control strip 41,42 just in time blocks the gear member 3 in through hole 11, and gear member 3 can not be rotated relative to through hole, that is can not rotate relative to this ratchet spanner, now, this ratchet spanner is equivalent to common wrench, and the nut being connected to connector 32 is and then rotated by the rotation of spanner.
When this middle controll block 43 turns to the right or the left side, as shown in Figure 4, this middle controll block 43 turns to the left side, and the spring 51 compressed between left control strip 41 and through hole 11, now, left control strip 41 returns to the side of through hole 11, be positioned at the accommodating position 111 on the left of through hole 11, now, left control strip 41 relieves the locking to gear member 32, but right control strip 42 has still propped up gear member 32, now gear member 3 counterclockwise can only rotate relative to through hole 11, because when gear member counterclockwise rotates, because right control strip 42 has spring with through hole 11, gear member 3 can drive right control strip 42 Compress Spring 52 and counterclockwise rotate, and gear member 3 is when rotating clockwise, right control strip 42 has propped up gear member 32 makes it not rotate.That is spanner is pulled, when spanner rotates counterclockwise time, gear member 3 and the nut be connected on connector 32 or bolt can follow spanner to rotate counterclockwise due to the locking action of right control strip 42, and spanner is when rotating clockwise, gear member 3 and the nut be connected on connector 32 or bolt can rotate counterclockwise relative to through hole 11, spanner can not be followed to turn round, therefore achieve the clockwise idle running of spanner, can be quick and pull spanner slack adjuster in little space.In like manner, when middle controll block 43 turns to the right, when spanner rotates clockwise, gear member 3 and the nut be connected on connector 32 or bolt can follow spanner to rotate clockwise, and spanner is when rotating counterclockwise, gear member 3 and the nut be connected on connector 32 or bolt can not follow spanner to turn round, and therefore achieve the counterclockwise idle running of spanner.
One end of described middle controll block 43 connects a direction button handsetting 45, and upper stop piece 6 is provided with the hole that middle controll block 43 position matches with this, the center of this middle controll block 4 be provided with extend from bottom to top and with the axially shrinkage pool in the same way of middle controll block 4, this lower stop piece 7 is provided with the perforate 72 matched with this shrinkage pool, this middle controll block 43 is inserted in through hole 11 by hole corresponding on upper stop piece 6, and this direction button handsetting 45 is positioned at outside described upper stop piece 6.
Described upper stop piece is also provided with at least one screw 61, be preferably two screws 61, be communicated to through hole 11 respectively, described lower stop piece 7 is provided with the screw 71 corresponding with this screw 61, screw 8 is inserted into through hole 11 from the screw 61 of upper stop piece, and be fixedly connected by the screw 71 on screw thread and lower stop piece 7, and then fixing upper stop piece 6 and lower stop piece 7.And the shrinkage pool be inserted in from the perforate 72 lower stop piece 7 with attachment screw 9 in described middle controll block 43, and then controll block 43 and lower stop piece 7 in the middle of connecting, and middle controll block 43 can be rotated around this attachment screw 9.
Preferably, the cross section of this middle controll block 43 is a wedge shape, and it has two side planes withstanding left and right brake(-holder) block respectively, and is positioned at the bottom surface of arc of bottom, and this bottom surface is convenient to this middle controll block 3 and is rotated in left and right both direction.
This ratchet spanner, adding man-hour, as long as respectively gear member, left and right brake(-holder) block and the parts such as middle controll block and direction button handsetting are made, then the through hole of Wrench head is put into, after pinch bar forges, as long as Wrench head utilizes punching process to make about one through hole of the same size when making, then mounting groove is processed at through hole two ends, as long as upper lower stop piece also processes respectively, the processing of each like this parts is very simple, and process velocity is also very fast.When mounted, as long as gear member, brake assemblies are put into through hole, then lower stop piece is put, then by screw 8, upper lower stop piece is fixed, then middle controll block 4 is inserted from upper washer with direction button handsetting 45, then attachment screw 9 is upwards inserted in from lower stop piece 7 middle controll block 4 to connect, interface completes installation.As long as inverted repeat above-mentioned action during dismounting, such structure, installing/dismounting is also very simple, just in case one of them has problems, carries out changing as long as also take apart.
This ratchet spanner, not only easy to process, and also installing/dismounting is also very convenient, is easy to the volume production of this ratchet spanner, enhances productivity, be also convenient to renewal part, extends the life-span of this ratchet spanner.
Although more than describe in detail preferred embodiment of the present utility model, should be expressly understood that, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
