Description

A kind of silk control shfting wrench
Technical field
The utility model relates to hardware & tools field, particularly a kind of silk control shfting wrench.
Background technology
Spanner is a kind of conventional installation and removal instrument.Utilize lever principle to twist bolt, screw, nut and other screw threads and tightly hold the opening of bolt or nut or the hand tools of trepanning firmware.Spanner is conventionally shaped with clamp holder portion in the one or both ends of shank and applies external force, just can twist bolt or nut and hold opening or the trepanning of bolt or nut.When use, apply external force along screw thread rotation direction at shank, just can twist bolt or nut.
Spanner is divided into two kinds substantially, solid wrench and adjustable wrench, and the former refers to the spanner that has fixing numeral to write, and the latter has been exactly monkey wrench.
1. fork spanner: one or both ends are shaped with the opening of fixed dimension, in order to twist nut or the bolt of certain size.
2. double offset ring spanner: two ends have the working end with hexagon ring or 12 jiaos of holes, are applicable to working space narrow and small, can not use the occasion of common wrench.
3. combination wrenches: one end is identical with single head fork spanner, the other end is identical with double offset ring spanner, and bolt or the nut of same size twisted at two ends.
4. adjustable wrench: A/F can regulate within the scope of certain size, can twist bolt or the nut of different size.The design feature of this spanner is that regular jaw is made with the flat pliers of serration recessed; Flat pliers mouth is made in moving jaw one end; The other end is made the recessed jaw with serration; Press worm screw downwards, moving jaw can take off rapidly, exchanges jaw position.
5. hook spanner: claim again crescent wrenches, for twisting the restricted jam nut of thickness etc.
6. box spanner: be commonly referred to as sleeve: it is by multiple sleeves with hexagon ring or 12 jiaos of holes and be furnished with the multiple accessories such as handle, extension bar and form, is specially adapted to twist status very narrow and small or cave in very bolt or the nut of depths.Sleeve has dividing of metric system and English system, although sleeve concave shape is the same, external diameter, length etc. is to design for the shape and size of corresponding device, and the unified regulation of country, so the design of sleeve is more flexible comparatively speaking, meets popular needs.Box spanner generally all has the collet head of a set of all size and the handle of waving, extension bar, universal joint, revolve tool joint, elbow handle etc. is used for being inserted in hexagonal (hexagon)nut.The collet head of box spanner is a recessed hexagonal cylinder; Spanner is made up of carbon structural steels or structural alloy steel conventionally, and Wrench head has the hardness of regulation, and centre and handle portion have elasticity.。
7. inner hexagon spanner: become the L shaped bar-shaped spanner of hexagonal, be exclusively used in and twist soket head cap screw.The model of inner hexagon spanner is that the size of bolt has national standard according to six sides' opposite side size.
Purposes: specialize in round nut fastening or that dismantle in lathe, vehicle, plant equipment and use.
8. torque spanner: it can demonstrate applied moment of torsion in the time twisting bolt or nut; Or when the moment of torsion applying arrives after setting, can send light or audible signal.Torque spanner is applicable to that torque is had to the assembling of regulation clearly.
Utility model content
The purpose of this utility model is to provide a kind of spanner that can regulate openings of sizes of new design, specifically a kind of silk control shfting wrench.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of silk control shfting wrench, comprise wrench body, screw mandrel, silk hole, handle and annex composition, it is characterized in that: main body and handle are integral type structure, between main body and handle, be provided with the screw mandrel that regulates openings of sizes to use, screw mandrel top is provided with the convex annex that can prevent that screw mandrel from coming off.
As preferably, being shaped as of described wrench body part: the circle of sealing, ellipse, hexagon, quadrangle, semi-enclosed arc, quadrangle, triangle, the position that wrench body part and screw mandrel are corresponding is: plane, concave surface, convex surface.
As preferably, described spanner screw mandrel part is full thread and part screw thread.
As preferably, described spanner silk bore portion is arranged in main body;
Described spanner silk bore portion is made up of the nut in main body and circular hole;
Described spanner silk bore portion is made up of the circular hole in nut and main body on handle.
As preferably, the shape style of pinch bar part is straight shape, bending, flat, circle, the position of handle can be arranged on screw mandrel above, below or both sides, handle can be replaced by screw mandrel.
As preferably, the top of described screw mandrel can be connected with screw mandrel by an annex, both can prevent that screw mandrel from coming off, also can increase the contact area of screw mandrel and screw, the afterbody of screw mandrel can make thicker than screw mandrel or carefully, also can do orthogonal, also can roll on flower, both attractive in appearance, can increase again friction, be beneficial to rotary screw.
When use, the screw of degree of tightness is put between the main body and screw mandrel front end of main body, by rotary screw afterbody, make the two reach suitable distance, or first adjust, be put on screw and finely tune again, make to reach between the two suitable distance, with both not too loose, prevent screw landing, also not too tight, convenient wrench is taken down, then rotary handle, drive screw rotates, and realizes the degree of tightness of screw.
The utility model, the screw that a kind of product can degree of tightness plurality of specifications, expanded the scope of application, simple in structure, conveniently manufactured, can be by forging, weld, the various ways processing such as casting, there is good market application foreground.
