Description

Fixing bolt or socket nut wrench

Technical field

The utility model relates to a kind of bolt or nut dismounting tool fields, more particularly to a kind of fixing bolt or nut Box spanner.

Background technique

Sleeve on existing box spanner in spite of the magnet for being mounted with to have certain attraction, but the magnetic on sleeve Iron is unable to bolt that absolute guarantee is dismounted or nut to the adsorption capacity to bolt or nut and does not fall off with sleeve, for example nut or Nut on bolt can directly fall off when encountering other object or deviate the magnet positions on sleeve and leave sleeve, that is, Say that obscission can often occur in nut or bolt and sleeve, nut or bolt fall into room machine equipment under normal circumstances for this Or can be found to operator add certain workload on the ground, but such as jet engine, the special knot of internal combustion engine airtightness The equipment of structure is not only difficult to find after falling into the objects such as nut or bolt, nor easily takes out, jet engine, internal combustion engine The interior accident that fatal crass is caused because of foreign matter is frequent occurrence.

Utility model content

The purpose of this utility model is to overcome deficiency in the prior art, provide a kind of structure is simple, manufacture is easy, It is easy to operate and there is the fixing bolt or socket nut wrench for not falling off function promptly to bolt or nut.

To achieve the above object, it includes sleeve, extension bar that the utility model, which provides a kind of fixing bolt or socket nut wrench, And handle, extension bar lower end are fixed with sleeve, extension bar upper end two sides are symmetrically fixed with handle；The bolt includes nut and screw rod, Hub internal bore shape is corresponding with the shape of nut or nut, and the extension bar is hollow round tube, and extension bar is connected to sleeve, extension bar It is inside placed with compression bar, the upper end of compression bar is fixed with knob, and the lower end of compression bar is fixed with pressing plate, and compression bar, which is located at below knob, to be provided with External screw thread, extension bar, which is located at handle, is provided with internal screw thread corresponding with the external screw thread on compression bar, the internal diameter of extension bar and sleeve Internal diameter is equal, and the outer diameter of pressing plate is less than or equal to the internal diameter of sleeve；

The sleeve is provided with arc pressuring plate, casing and bottom plate, and the side of described sleeve pipe is provided with flat with casing axis Capable opening, the internal diameter and outer diameter of casing are equal with the internal diameter of extension bar and outer diameter difference；The upper end of described sleeve pipe is relative to opening Side be fixedly connected with arc pressuring plate, the radian of arc pressuring plate is 180 °, under the upper end and extension bar of arc pressuring plate End is fixedly connected；The lower end of casing is fixed with the circular bottom plate equal with casing diameter, the central point of bottom plate to lower end Opening is provided with open slot.

The height of described sleeve pipe is less than or equal to the height of nut and nut, and the height of arc pressuring plate is greater than nut and spiral shell Female height, be open diameter equal with the width of open slot and being all larger than screw rod.

The utility model beneficial effect is: the fixing bolt or socket nut wrench structure of the utility model are simple, manufacture It is easy；After nut or nut and fixated body are directly rotated several circles by disassembly nut or nut Shi Xianyong box spanner counterclockwise Nut or nut can be made to be placed in casing, and rotate knob and the pressing plate in fixed link is pressed on nut or nut so that nut Or nut is tightly held in casing very much, and it is not only easy to operate, and nut or nut are fixed bar and are pressed in casing So that nut or nut are not easy to separate with sleeve on bottom plate, that is, realizes box spanner and make nut when dismantling nut or nut Or nut is fixed bar and is pressed in casing and is fixed well, avoids nut or nut and is easy the disadvantage fallen in disassembly End；Nut or nut are first placed into casing when nut and with revolving clockwise after pressing plate clamping nut or nut by installation nut Because nut or nut are by the bottom under pressing plate and casing when nut or nut can be allowed to fix after turning several circles, therefore install nut or nut Plate mutually compresses and not easily to fall off.

The fixing bolt of the utility model or socket nut wrench are described further with reference to the accompanying drawing.

Specific embodiment

As shown in Figure 1, Figure 2 and Fig. 5 shown in, the fixing bolt or socket nut wrench of the present embodiment include sleeve 1, extension bar 2 and Handle 3,2 lower end of extension bar are fixed with sleeve 1, and 2 upper end two sides of extension bar are symmetrically fixed with handle 3.Bolt includes nut 4 and screw rod 5, 1 internal via shape of sleeve is corresponding with the shape of nut 4 or nut.Extension bar 2 is hollow round tube, and extension bar 2 is connected to sleeve 1, connects Compression bar 6 is placed in bar 2, the upper end of compression bar 6 is fixed with knob 7, and the lower end of compression bar 6 is fixed with pressing plate 8, and compression bar 6 is located at knob 7 Lower section is provided with external screw thread 9, and extension bar 2, which is located at handle 3, is provided with internal screw thread 10 corresponding with the external screw thread 9 on compression bar 6, connects The internal diameter of bar 2 is equal with the internal diameter of sleeve 1, and the outer diameter of pressing plate 8 is less than or equal to the internal diameter of sleeve 1.

As shown in figure 3, sleeve 1 is provided with arc pressuring plate 11, casing 12 and bottom plate 13, the side of casing 12 be provided with The parallel opening 14 of 12 axis of casing, the internal diameter and outer diameter of casing 12 are equal with the internal diameter of extension bar 2 and outer diameter difference.Casing 12 Upper end is fixedly connected relative to 14 sides of opening with arc pressuring plate 11, and 11 radian of arc pressuring plate is 180 °, arc pressuring plate 11 upper end is fixedly connected with the lower end of extension bar 2；The lower end of casing 12 is fixed with the circular bottom plate 13 equal with 12 diameter of casing, Open slot 15 is provided at the central point of bottom plate 13 to the opening 14 of 12 lower end of casing.The height of casing 12 is less than or equal to nut 4 and nut height, the height of arc pressuring plate 11 is greater than the height of nut 4 and nut, the width of opening 14 and open slot 15 Diameter that is equal and being all larger than screw rod 5.

As shown in Figures 4 and 5, when bolt is from fixed object or nut is dismantled from bolt, first by nut 4 or Nut is unclamped from fixed object when being greater than the height of casing 12 to 5 height of screw rod for exposing fixated body, then by casing Opening 14 and open slot 15 on 12 are directed at screw rod 5 can be by nut 4 or nut merging casing 12, and then rotating knob 7 will press Plate 8 is pressed on nut 4 or nut and can rotate counterclockwise handle 3 with hand and can dismantle bolt or nut from fixation Get off.Because nut 4 or nut are fixed in casing 12 by pressing plate 8, screw rod 5 is also fixed in the open slot 15 of bottom plate 13, institute To be always positioned in casing 12 in the nut 4 of bolt or nut bolt during being disassembled or nut, to effectively keep away Exempt from bolt or nut and separates the phenomenon that falling off with sleeve 1.

Nut 4 is installed or when nut, first nut 4 or nut is placed into casing 12 and with 8 clamping nut 4 of pressing plate or spiral shell Imperial mother's alignment bolt hole or screw rod can allow nut 4 or nut to be fixed after rotating clockwise several circles, therefore when installation nut 4 or nut Because that nut 4 or nut are mutually compressed by the bottom plate 8 under pressing plate 8 and casing 12 is not easily to fall off.
