Below in conjunction with drawings and Examples the utility model is elaborated:

As shown in Figures 2 and 3, the ratchet spanner preferred embodiment of the utility model multi-angle location comprises a lever unit 10, one and is hubbed on the positioning unit 30 that driving head 20 on this lever unit 10 and are arranged on this lever unit 10 and these driving head 20 articulated sections.

This lever unit 10 has the blocking groups 13 that operating parts 12 that a lever spare 11, one and this lever spare 11 be articulated and two are located at this lever spare 11 and operating parts 12 articulated sections.

This lever spare 11 has a binding end 112 that grips end 111 and and these gripping end 111 opposite settings, this binding end 112 is the flat bulk, and has second confined planes 114 of one first confined planes 113 and and these first confined planes, 113 opposing settings.

This operating parts 12 has that an operative end 121, one and this operative end 121 are opposite to be provided with and with respect to the pivot joint end 122 of this binding end 112, two pivot arm 123 and accommodation spaces 124 between 123 on described pivot arm that are oppositely arranged on this operative end 121, this pivot joint end 122 has two pivot ears 125 that are oppositely arranged and one between 125 in the described pivot ear and the groove 126 that can be inserted in for this binding end 112, and described pivot ear 125 respectively has one adjacent to this groove 126 and the plane 127 relative with this first and second confined planes 113,114.Described pivot arm 123 respectively has a medial surface 128 adjacent to this accommodation space 124.

Described blocking group 13 respectively has three intervals 90 degree and is arranged with blocking hole 131 on first and second confined planes 113,114 of this binding end 112, one and described blocking hole 131 and is oppositely arranged and is installed in spring steel ball 132 in the pivot ear 125 relative with this first and second confined planes 113,114, and described blocking hole 131 is to arrange in the form of a ring and can supply these spring steel ball 132 inlay cards.

This driving head 20 is to utilize two fulcrum bolts 21 to be hubbed on the pivot arm 123 of this lever unit 10 and just be installed with in this accommodation space 124, and have a driving part that is flat column 22, one be located at these driving part 22 1 sides and relative with one of them medial surface 128 first locating surface 23, one be located at these driving part 22 opposite sides and second locating surface 24 relative with another medial surface 128, this first and second locating surface the 23, the 24th is opposing setting.

This positioning unit 30 has 8 intervals 45 degree and is arranged with location shrinkage pool 31 on this first locating surface 23, one and described location shrinkage pool 31 and is oppositely arranged and is installed in spring steel ball 32 in the pivot arm 123 relative with this first locating surface 23 and one to should spring steel ball 32 and be arranged on secondary spring steel ball 33 in another pivot arm 123, described location shrinkage pool 31 is to arrange in the form of a ring and can supply these spring steel ball 32 inlay cards, but these secondary spring steel ball 33 elastic top are held on the second corresponding locating surface 24.

Again as shown in Figure 3, after whole assembly is finished, the lever spare 11 and the operating parts 12 of this lever unit 10 is to be pivotly to link, and after this lever spare 11 pivots with operating parts 12, be spring steel ball 132 inlay cards therein in blocking hole 131 and obtain the location that utilize blocking group 13, and this driving head 20 also can produce pivot with respect to pivot arm 123, and also can make spring steel ball 32 inlay cards of this positioning unit 30 therein in locating hole 31 after pivoting, and utilize these secondary spring steel ball 33 elastic top to be held on the second corresponding locating surface 24 and obtain the location.

And as shown in Figure 4, when operation screw of desire in narrow operating space or nut, be to utilize this driving part 22 to cooperate a sleeve 100 to use, and make that the lever spare 11 of this lever unit 10 is linearly with operating parts 12, these lever unit 10 integral body then be switched to should driving part 22 axially, utilize this lever unit 10 of rotation just can reach the purpose of operating screw or nut.And in operating process, even the operator discharges this lever unit 10, then this lever unit 10 still can keep linearity, so quite convenient in operation.

Fig. 3 and shown in Figure 5 and for example, when the screw of desire operation or nut periphery have other objects to hinder, can make the lever spare 11 of this lever unit 10 be pivoted relative to each other linearly with operating parts 12, and spring steel ball 132 inlay cards that utilize blocking group 13 are therein in blocking hole 131, and make this lever spare 11 and the angle of operating parts 12 can obtain to fix.And these lever unit 10 integral body pivot with respect to this driving head 20 and are an angle, and spring steel ball 32 inlay cards that utilize this positioning unit 30 are therein in locating hole 31, and utilizing these secondary spring steel ball 33 elastic top to be held on the second corresponding locating surface 24, the angle after can making this lever unit 10 pivot with respect to this driving head 20 can obtain to fix.And in operating process, even the operator discharges this lever unit 10, then this lever unit 10 still can keep meander-like, so quite convenient in operation.

Fig. 3 and shown in Figure 6 for another example, when the screw of desire operation or nut periphery there is no that other objects hinder and need bestow big torsion the time, can make the lever spare 11 of this lever unit 10 be pivoted relative to each other and be 90 degree shapes with operating parts 12, and spring steel ball 132 inlay cards that utilize blocking group 13 are therein in blocking hole 131, and the angle after making this lever spare 11 and operating parts 12 pivot can obtain to fix.And these lever unit 10 integral body are vertical configuration with respect to the axial pivot of this driving head 20 again, and spring steel ball 32 inlay cards that utilize this positioning unit 30 are therein in locating hole 31, and utilizing these secondary spring steel ball 33 elastic top to be held on the second corresponding locating surface 24, the angle after can making this lever unit 10 pivot with respect to this driving head 20 can obtain to fix.And in operating process, even the operator discharges this lever unit 10, then this lever unit 10 still can keep 90 degree shapes, so quite convenient in operation.

Therefore, ratchet spanner of the present utility model, it is the adjustment that can utilize this lever unit 10 to produce 8 kinds of angles with respect to this driving head 20, and it is fixing to utilize this positioning unit 30 that adjusted angle is obtained, the adjustment that utilizes this lever spare 11 to produce 3 kinds of angles with respect to this operating parts 12 again, and it is fixing to utilize blocking group 13 that adjusted angle is obtained, then this ratchet spanner just can cooperate the different operating occasion, different application of force demands and adjust 24 kinds of operation forms, and adjusted lever unit 10 can produce the location with respect to this driving head 20, angle after these lever unit 10 complications also can obtain to fix, so quite convenient on using.
