Abstract
The utility model relates to a simple ratchet spanner, comprising three parts as a ring ratchet (1), an arc ratchet (2), and a handle (3). The utility model is characterized in that the ring ratchet (1) comprises 2-4 pieces of ratchet components (6) with a ratchet bar (5), the ratchet components are connected to a movable ring by the a connecting piece (4), two ends of the ring are respectively fixed to the handle (3); the arc ratchet (2) whose one end is connected with the handle (3) is arranged on the other end of the handle, the ratchet bar (5) is arranged on the hinged surface between the handle (3) and the arc ratchet (2). The utility model has the advantages that the structure is simple, the cost is low, the time and efforts are saved; the utility model can adapt to different operating environment.
Description
Technical field: the utility model relates to a kind of hand tools, definite a kind of simple and easy pawl wrench of saying so.
Background technology: generally be used at present to tighten or the instrument that unclamps various nuts (bolt), water pipe and twisting circle, special-shaped work package is polytype spanner and plumbing combination pliers etc.In real work, as meet when stating dissimilar work packages, must possess multiple spanner and plumbing combination pliers, not only carry inconvenience, and it is also inconvenient to operate, thereby also influenced operating efficiency.
Summary of the invention: the purpose of this utility model, exactly in order to address the above problem, provide a kind of simple and easy pawl wrench, it can be effectively used to tighten or unclamps various nuts (bolt), water pipe and twisting circle, special-shaped work package, and can improve its operating efficiency.
Technical solution of the present utility model is: simple and easy pawl wrench, constitute by handle, ring-type ratchet and arc ratchet, it is characterized in that: the ring-type ratchet is by the pawl assembly of the 2-4 sheet band ratchet loose collar that is formed by connecting, and the two ends of ring are separately fixed on the handle; The handle other end is equipped with an arc ratchet, and arc ratchet one end is connected with handle, and the occlusal surface between handle and the arc ratchet is provided with ratchet.
The utility model has adopted the structure that is connected to each other the loose collar that forms by the ratchet of 2-4 sheet band ratchet, is characterized in arbitrarily changing the shape of ring, can adapt to the needs of nut (bolt), water pipe and the special-shaped work package of various models.In use, as long as the ring-type ratchet is enclosed within on the work package, turn round to certain angle, ratchet just can firmly be clamped work package, and is fulcrum with the handle, produces powerful moment of torsion, tightens like a cork or unclamps work package.The arc ratchet then is applicable to the work package that size is less, and ratchet that can be on handle is clamped less work package so that tighten or unclamp.
The utility model is simple in structure, and is with low cost, easy to use, time saving and energy saving, can adapt to different working environments preferably.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
1. ring-type ratchet, 2. arc ratchet, 3. handle, 4. connector, 5. ratchet, 6. pawl assembly
The specific embodiment: referring to Fig. 1, simple and easy pawl wrench is made of ring-type ratchet 1, arc ratchet 2, handle 3 three parts, and ring-type ratchet 1 is by the pawl assembly 6 of 3 band ratchets 5, by connector 4 loose collar that is formed by connecting, the two ends of ring are separately fixed on the handle 3; The handle other end is equipped with arc ratchet 2, and arc ratchet 2 one ends are connected with handle 3, and the occlusal surface between handle 3 and the arc ratchet 2 is provided with ratchet 5.
In use, as long as ring-type ratchet 1 is enclosed within on the work package, turn round to certain angle, ratchet 5 just can firmly be clamped work package, and is fulcrum with handle 3, produces powerful moment of torsion, tightens like a cork or unclamps work package.2 on arc ratchet is applicable to size less than 8 millimeters work package, and ratchet 5 that can be on handle is clamped work package so that tighten or unclamp.
