2. rain brush connecting rod D2 is inserted among the set oblong inserting hole D12 in connector D1 rear end, and the set boss point D21 of rain brush connecting rod D2 is sticked among the circular hole D13;

Promptly can be assembled into as shown in Figure 8 structure according to above-mentioned steps, and make that rain brush seat A1 is the center of circle and can do a suitable angle rotation with fixed link A12.

The comprehensive above-mentioned various rain brush connection structure assembling mode of commonly using as can be known, rain brush connecting rod A4 as shown in Figure 1, with rain brush connecting rod B1 shown in Figure 3, with rain brush connecting rod C1 shown in Figure 5, all only can use with a kind of tip connector A2 alive, and can't use as shown in Figure 7 connector D1, and rain brush connecting rod D2 shown in Figure 7 also is only applicable to connector D1 shown in Figure 7, and can't use as shown in Figure 1 work tip connector A2, therefore present rain brush production firm is when selling the windshield wiper seat, must have two kinds of connectors, just tip connector A2 alive as shown in Figure 1 and as shown in Figure 7 connector D1, in the hope of the multi-form rain brush connecting rod that is applicable to that different automobile types has, not only improve the productive costs of rain brush production firm, and for the customer, remove outside the connector that itself is suitable for, remaining another connector has no purposes at all and must abandon, make unnecessary rubbish, caused problem of environmental pollution indirectly, moreover, connector D1 as shown in Figure 7, its rear end is provided with an oblong inserting hole D12, system plants for rectangular rain brush connecting rod D2 and uses, but since this oblong inserting hole D12 around be the fixed sealing enclosed, have no elasticity and can say, so during rectangular rain brush connecting rod D2 insertion, very easily damage inserting hole D12, very the person is broken.

Creator of the present utility model is promptly improved at above-mentioned all serious disappearances, innovation, and create windshield wiper connector structure of the present utility model, extremely shown in Figure 11 as Fig. 9, both sides of the present utility model are provided with shaping slice 1, the front end of this shaping slice 1 is provided with preceding grab 11, back grab 12, be provided with a folder type connecting buckle 2 in 1 of this shaping slice, the rear end on the upper strata of this folder type connecting buckle 2 is provided with a circular hole 21, the rear portion of the lower floor of this folder type connecting buckle 2 is provided with a movable spring slice 22, moreover, in this shaping slice 1, the bottom of this folder type connecting buckle 2 is provided with a fixing ditch 13, and this fixedly is provided with the tip engaging ditch 14 of living in ditch 13 rears.

As shown in figure 12, as the utility model and the rain brush seat A1 that commonly uses, when the tip A3 that lives cooperates with rain brush connecting rod A4, the tip A3 that will live earlier inserts among the set tip alive hole A13 of rain brush seat A1, and the preceding engaging section A31 of this work tip A3 protrudes from outside the tip alive hole A13 by the tip hole 13 of living, the back engaging section A32 of this work tip A3 then is sticked among the tip alive hole A13, again fixedly ditch 13 of the present utility model is positioned on the set fixed link A12 of this rain brush seat A1, and this work tip engaging ditch 14 just is positioned at the set A13 place, the tip alive hole of rain brush seat A1, can engage mutually with the back section of the engaging A32 of the tip A3 that lives, then that rain brush connecting rod A4 is the set hole A41 that revolves aims at the preceding engaging section A31 protrude from the outer tip A3 alive of this works tip hole A13, and inwardly pushes and make rain brush connecting rod A4 be sticked in wherein.

As shown in figure 13, when the utility model with the rain brush seat A1 that commonly uses, when rain brush connecting rod B1 cooperates, be that fixedly ditch 13 of the present utility model is positioned on the set fixed link A12 of this rain brush seat A1, and this work tip engaging ditch 14 just is positioned at the set A13 place, the tip alive hole of rain brush seat A1, again the tip B11 alive on the rain brush connecting rod B1 is partly inserted among the set tip alive hole A13 of rain brush seat 3, can make the engaging section B12 on this work tip B11 be sticked among the set tip alive hole A13 of rain brush seat A1, wear the tip engaging ditch 14 of making a living simultaneously, so promptly finish the stack-mounted action.

As shown in figure 14, as the utility model and the rain brush seat A1 that commonly uses, when rain brush connecting rod C1 cooperates, be that fixedly ditch 13 of the present utility model is positioned on the set fixed link A12 of this rain brush seat A1, and rotation the utility model makes it bottom-up, the hook of again that this rain brush connecting rod C1 front end is set binding hook C11 is facing direction of the present utility model and is inserting among the set mounting groove A11 of rain brush seat A1, to link hook C11 more up draws, make that linking hook C11 is sticked in the set preceding grab 11 of the utility model front end, because the spacing of this back grab 12 is less than the spacing of this preceding grab 11, so when this width that links hook C11 slightly hour, can slip over this preceding grab 11 and take advantage of a situation and be sticked in this grab 12, be unlikely making this binding hook C11 drop out.

As shown in figure 15, as the utility model and the rain brush seat A1 that commonly uses, when rain brush connecting rod D2 cooperates, be that fixedly ditch 13 of the present utility model is positioned on the set fixed link A12 of this rain brush seat A1, and rotation the utility model makes, and its bottom is floating to be higher than on the rain brush seat A1, the front end that is rectangle with rain brush connecting rod D2 is inserted in the set folder type connecting buckle 2 of the utility model again, because the lower floor of this folder type connecting buckle 2 is provided with a movable spring slice 22, so when this rain brush connecting rod D2 inserts, have a natural extension power, can be easily this rain brush connecting rod D2 is inserted and needn't worry can damage this folder type connecting buckle 2, and engage mutually by the set boss point D21 of the set circular hole 21 in these folder type connecting buckle 2 upper stratas and this rain brush connecting rod D2, be fixed in this folder type connecting buckle 2 when making this rain brush connecting rod D2 true.

With reference to figure 9, and it is comprehensive as can be known above-mentioned, windshield wiper connector structure of the present utility model is really applicable to the rain brush connecting rod of various different types, not only can reduce the fringe cost of windshield wiper manufacturer, and be provided with a movable spring slice 22 because of it, so the connector more generally commonly used has more dilatancy and impregnability, be one to have the new creation of height practical value in fact.
