Abstract

The utility model provides an integrated carriage wrench comprising a handle body, a ratchet sleeve fixed by a stressed top is arranged in the cavity of the head, and the cylindrical of the ratchet sleeve is a ratchet, a plurality of telescopic polygon sleeves of different sizes are arranged in the ratchet sleeve, wherein sleeve openings in one side of each sleeve and the openings of adjacent sleeves dislocate, and a ratchet reversible mechanism operates the ratchet sleeve to rotate to loose or fasten the bolts, which comprises two brace rods, two compression springs, a milling cam, a call button, and a ratchet reversible mechanism. The utility model integrates the light single pieces of the sleeve and is formed according to different specifications and sizes in groups, which has the advantages of novel design, simple structure and convenient in use, which solves the inconvenience of carrying and keeping several wrenches.

Description

The integrated sleeve spanner

Technical field

The utility model relates to a kind of box spanner, especially a kind of box spanner of multilayer intussusception.

Background technology

Box spanner is to be used for tightening or loosening the bolt of polygon head and screw, as hexagon, quadrangle, with hexagon is many, available spanner has fork spanner, adjustable wrench, double offset ring spanner, box spanner or the like, all exist common drawback: the scope of application is narrow, a spanner can only be pulled a kind of bolt and screw of or two kinds of specifications, though adjustable wrench can be pulled more specification, but skid easily, for the hex bolts and the screw of twisting plurality of specifications commonly used, the user need have various, big and small spanner is placed in the special box, this is to making, use, much more like this carry and even keeping spanner, all be very inconvenient.In recent years, the home and abroad all proposes to adopt the multilayer sleeve that slides over each other and cooperate, to enlarge the scope of application of a box spanner, promptly bring in the twisting hex bolts with one of multilayer sleeve, the other end is equipped with fixture and spring reverse motion, its complex structure, and marketing is had any problem.

Summary of the invention

Goal of the invention of the present utility model is to overcome the defective of prior art and a kind of simple in structure, light-duty integrated sleeve spanner that can tighten or loosen the plurality of specifications size that has is provided.

Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of integrated sleeve spanner, it comprises handle body, be provided with the ratchet sleeve of fixing by gland in the handle body head chamber and handle the ratchet reversible mechanism that ratchet sleeve rotates, this mechanism comprises two struts with ratchet sleeve ratchet one way engagement, pushing tow has stage clip on each strut, the cam that promotes the commutation of strut and ratchet sleeve ratchet engagement is driven through driving lever by toggle, it is characterized in that being provided with in the described ratchet sleeve polygon sleeve of the mutual intussusception of multilayer different size, each sleeve one side opening, and the opening of adjacent sleeve misplaces mutually.

Described adjacent sleeve openings is the opposite side dislocation.

Described polygon sleeve is hexagon or quadrangle or quincunx sleeve.

Compared with prior art, the utility model carries out the sleeve single-piece of lightness integrated, arranges the grouping installation step by step by the specification size and forms the integrated sleeve spanner together, it is novel, simple in structure, easy to use, solved the inconvenience of carrying, taking care of a plurality of spanners.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the sleeve sectional view.

The specific embodiment

By above-mentioned accompanying drawing the utility model embodiment is elaborated again below.

Shown in Fig. 1～3, the integrated sleeve spanner has one handle body 1, is provided with in the handle body head chamber by gland 4 through the fixing ratchet sleeve 2 of screw 12 and handle the ratchet reversible mechanism of the two-way rotation of ratchet sleeve.

Ratchet sleeve 2 is the cover tubular, cylindrical has ratchet 9, interior is the Hexagonal jacket of specification 24mm, can be directly the bolt screw of specification 24mm be tightened or loosened, being provided with 4 layers of specification in the Hexagonal jacket of 24mm is 22mm, 19mm, 17mm, the hexagon sleeve 3 of the mutual intussusception of 14mm, the Hexagonal jacket of 4 layers of different size adopts spring steel to make, be pressed into the positive hexahedron of tubulose with the thick steel spring plate of 1～1.5mm, one side leaves inc opening 11, adjacent sleeve openings opposite side dislocation, utilize material elasticity to be fit into one by one in the ratchet sleeve 24mm Hexagonal jacket, make to produce the fastening force that forms because of the elasticity extruding between sleeve and the sleeve, promptly become many structural shape of box spanner.If the 14mm specification is just directly used,, can use, by that analogy during use if use 17mm specification is just up shifted the sleeve of 14mm onto certain altitude.

The ratchet reversible mechanism of handling ratchet sleeve 2 rotations comprises and two struts 8 of ratchet sleeve ratchet 9 one way engagement that pushing tow has stage clip 10 on each strut, and the cam 7 that promotes the commutation of strut and ratchet sleeve ratchet engagement is driven through driving lever 6 by toggle 5.

Strut and ratchet sleeve ratchet do not mesh above shown in Figure 2, unpowered transitive relation, below strut and ratchet sleeve ratchet be in engagement, during clockwise control crank body, ratchet sleeve clockwise rotates, hex bolts is fastened; When stirring the toggle backward rotation, following driving lever is thrown off the engagement with the ratchet sleeve ratchet, above driving lever be in engagement, during the control crank body, ratchet sleeve rotates counterclockwise counterclockwise, hex bolts is released.

Claims

1, a kind of integrated sleeve spanner, it comprises handle body (1), be provided with the ratchet sleeve of fixing by gland (4) (2) in the handle body head chamber and handle the ratchet reversible mechanism that ratchet sleeve rotates, this mechanism comprises two struts (8) with ratchet sleeve ratchet (9) one way engagement, pushing tow has stage clip (10) on each strut, the cam (7) that promotes the commutation of strut and ratchet sleeve ratchet engagement is driven through driving lever (6) by toggle (5), it is characterized in that being provided with in the described ratchet sleeve (2) the polygon sleeve (3) of the mutual intussusception of multilayer different size, each sleeve one side opening (11), and the opening of adjacent sleeve misplaces mutually.

2, integrated sleeve spanner according to claim 1 is characterized in that described adjacent sleeve openings (11) is the opposite side dislocation.
