Abstract
The utility model relates to a three-jaw bidirectional enhanced spanner, which comprises an upper disk, a lower disk, a sun great, connecting rod gears, connecting rods, and jaw posts, wherein the sun gear is arranged between the upper disk and the lower disk; three connecting rod gears are uniformly distributed at the periphery of the sun gear, and are engaged together; each connecting rod gear comprises a gear and a connecting rod which are connected together; each connecting rod is connected with a jaw post; the sun gear is provided with a convex post; one end of the convex post passes through a hole in the center of the upper disk; the gear and the connecting rod of each connecting rod gear are integrated into a whole; and the jaw posts are connected to the outer ends of the connecting rods through clamp nuts. The three-jaw bidirectional enhanced spanner has the advantages that: the connecting rod gears are firm and durable; the jaw posts are convenient to detach and replace; the stress surface of the sun gear is increased; and the operating stability is improved.
Description
Technical field
The utility model relates to the automotive service set technical field, relates in particular to the two-way reinforced spanner of a kind of three-jaw.
Background technology
Original three-jaw Two-way spanner, the gear of its link gear and connecting rod rupture during use easily for being welded to connect; Secondly, central gear is set to hollow structure, by passing instrument realization work wherein, and also wearing and tearing or distortion easily of central gear hole like this; Moreover its pawl post is connected to welding with connecting rod and is connected, and the pawl post can't be dismantled, and when the pawl post wore and tore, whole three-jaw spanner also just can't use.
The utility model content
The utility model provides a kind of three-jaw two-way reinforced spanner for avoiding above-mentioned deficiency.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the two-way reinforced spanner of a kind of three-jaw, it comprises disk, lower disc and central gear, described central gear is arranged between disk and the lower disc, the periphery of central gear is three link gears of distribution evenly, and mesh together, described each link gear comprises gear and the connecting rod that links together, connect a pawl post on each connecting rod, described central gear is provided with projection, and an end of projection passes the hole of disc centre, the gear and the connecting rod of described each link gear are structure as a whole, and the pawl post of described each link gear is connected the outer end of connecting rod by clamp nut.
Further, described central gear and projection are structure as a whole.
Further, described pawl post is provided with anti-skidding line.
Further, described projection is six rib projections.
The beneficial effects of the utility model are: link gear is sturdy and durable, and pawl post dismounting and change is convenient, and the central gear stress surface increases, and has improved the stability of operation.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model side view.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As depicted in figs. 1 and 2, the two-way reinforced spanner of a kind of three-jaw, comprise three link gears 1, three pawl posts 2, a central gear 6 and a upper and lower disk, wherein, central gear 6 places between the lower disc, central gear 6 is provided with six rib projections 3,3 concentricity gear 6 cast of six rib projections are integrally formed, than the setting in the hole, hollow four directions of central gear 6 before, the focusing surface of external force when six rib projections 3 have increased spanner work, thereby strengthened stressed degree, guaranteed the stability and the high efficiency of operation.Central gear 6 peripheries are provided with three link gears 1, the characteristics of link gear 1 be gear on it with connecting rod one castable, so, be connected with the gear welding than connecting rod before, the working strength of link gear 1 has just increased greatly.The outer end of connecting rod, be provided with three pawl posts 2 perpendicular to the connecting rod horizontal direction, pawl post 2 is fixed in the outer end of connecting rod by clamp nut 4, pawl post 2 is set to the overstriking type, be provided with anti-skidding line 5 on the cylinder, than the pawl post that welding is before fixed, it is processed intensity increase and is easy to dismounting and change, both reduce the cost of changing whole spanner, strengthened the effect of using again.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
