Abstract

The utility model relates to a quick hexagonal wrench and aims at providing a quick hexagonal wrench which can be effectively applied to parts of a hexagonal prism shape. The quick hexagonal wrench has the characteristics of quickness in adjustment of a wrench port, stability in clamping and simple structure. The technical scheme provided by the utility model is that the quick hexagonal wrench comprises a handle and a main wrench head, wherein a shaft hole is formed in one end of the handle; the main wrench head can be rotationally riveted in the shaft hole; the quick hexagonal wrench is also provided with a movable wrench head which can slide on a guide rail of the main wrench head; a clamping surface for parts on the main wrench head and a clamping surface for the parts on the movable wrench head are mutually matched to form the wrench port for clamping hexagonal prism parts; and gear sets which are mutually meshed to push the movable wrench head to slide to further adjust the space between the main wrench head and the movable wrench head are arranged between the handle and the movable wrench. The guide rail is positioned on the main wrench head and linearly penetrates through grooves in the end surfaces on two sides of the main wrench head; sliding bars which are matched with the grooves and can be embedded into the grooves to slide are formed on the movable wrench head; and the gear sets comprise racks arranged on the sliding bars and incomplete gears which are arranged at the top end of the handle and are matched with the racks.

Description

The hexagonal speeder wrench

Technical field

The utility model relates to a kind of speeder wrench, specifically is the hexagonal speeder wrench.

Background technology

Speeder wrench is the common tool in pipeline installation and the repair work, is mainly used in fastening or dismounting micro metal and cylindrical component.The adjusting that speeder wrench is realized pulling mouthful spacing through rotating main spanner is to adapt to the part of different size; But existing speeder wrench mainly relies on the main spanner two clamping faces to bite part with common cooperation of the bite on handle top; Though have the advantage of regulating fast, can be fit to different big or small parts; But owing to be not regular hex surface, nibble easily when parts such as the hex bolts of routine, hex nut are pulled and destroy the corner angle of parts, influence the continuation use of parts the clamping contact point of part; Thereby be not suitable for bolt, nut, the range of application of the speeder wrench that reduces to know clearly.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of speeder wrench is provided, and this speeder wrench should be able to be effectively applied to the parts of six prismatic profiles, and have pull mouthful regulate fast, clamping is stable and characteristic of simple structure.

The technical scheme that the utility model adopts is: the hexagonal speeder wrench; Comprise that an end is shaped on the handle of axis hole, is riveted on the main spanner of axis hole rotationally; It is characterized in that; This spanner also is furnished with the spanner alive that can on main spanner guide rail, slide, on the said main spanner on the clamping face of parts and the spanner of living the clamping face of parts being complemented each other to form the mouth of pulling of a clamping hexagon part; Be shaped between said handle and the spanner alive and can intermesh to promote the gear train that spanner alive slides and then regulates main spanner and spanner spacing alive.

Said guide rail is to be positioned on the main spanner and straight line connects the groove of both sides end face, is shaped on the groove coupling on the said spanner alive and can embeds the draw runner that slides in the groove.

Said gear train comprises: the partial gear that is formed on the tooth bar on the draw runner and is formed on the handle top and matches with tooth bar.

The number of teeth of said partial gear is 2.

The beneficial effect of the utility model is: the utility model is with the clamp structure on some two sides in original speeder wrench; Interior six shapes of making clamping hexagon part into are pulled mouth; Not only can the stable holding bolt, hexagon parts such as nut, and can parts not damaged; In addition, only need turning handle, just can make spanner alive parallel mobile, reached quick adjustment and pulled a mouthful spacing, be fit to the purpose that different size zero parts use; Have good market prospects.

The specific embodiment

As shown in Figure 1, the hexagonal speeder wrench comprises handle 1, main spanner 3 and the spanner 4 of living; The top of handle is shaped on axis hole 2, and this end is shaped on the partial gear of being made up of several handle teeth 7 (being generally 2) (the handle tooth is that axis is the circle-shaped outer face that is distributed in this end with the axis hole) simultaneously.Be shaped on a groove 5 as guide rail (among Fig. 4 visible groove be dovetail groove) on the main spanner, this groove is produced on central authorities and the both sides end face that straight line connects main spanner of the thickness direction of main spanner; Axis hole is vertical with groove and through groove, main spanner riveted joint (through rivet 9 riveted joints) also can be rotated around axis hole in this axis hole.Be shaped on the draw runner 6 (visible among Fig. 5, Fig. 6) that matees with this groove on the spanner alive, the spanner of living can be engaged in through the embedding of draw runner and groove on the main spanner and slide.Also be shaped on the tooth bar that meshes with the handle tooth on the draw runner, tooth bar is formed (the spanner tooth of living linearly is distributed in the top of draw runner shape) by several spanner tooth 8 (being generally 3) of living; When main spanner is fixed; Turning handle makes the handle tooth rotate (being similar to gear rotates) around axis hole; The spanner tooth of living is promptly driven by the engagement of handle tooth; Straight line moves to left or moves to right in main spanner upper edge to make spanner alive, and then reaches the effect that mouth (by forming between main spanner clamping face and the spanner clamping face alive) distance is pulled in adjusting.

When using the hexagonal speeder wrench, be enclosed within main spanner on bolt or the nut earlier, make to direction turning handle then and pull a mouthful spacing and reduce near the work spanner; When pulling a mouthful spacing when being decreased to spanner alive and also biting bolt or nut,, but therefore continue by identical direction turning handle wrenching bolt or nut because stuck can't the continuation of spanner that live move; After this backward rotation handle just can take off the hexagonal speeder wrench like a cork on bolt or nut.
