Abstract
The utility model belongs to improvement on the structure of a socket spanner, and particularly relates to an improved socket spanner. Two ends of a connecting rod are respectively and fixedly connected with a large socket and a small socket that are structurally characterized in that the circumference end surface at the outer end of a cylindrical socket seat is uniformly distributed with six elastic strip plates which are patulous in a radial pattern; mating surfaces matched with the hexagonal surfaces of hexagonal nuts are arranged on the inner side surfaces of the outer ends of the elastic strip plates; threads are arranged on the outer cylindrical surface of the socket seat; a tightening ring sleeve is formed by a cylinder sleeve and a conical sleeve connected with the cylinder sleeve into a whole; the large end of the conical sleeve faces outwards; the inner wall of the cylinder sleeve is connected with the socket seat by threads in a matching way; the inner wall of the conical sleeve is matched with the outer side surface of the six elastic strip plates so as to enable the restrained mating surfaces of the six elastic strip plates to be matched with the hexagonal nuts; and a horizontal through hole for installing a forcing rod is arranged on a connecting rod. The improved socket spanner is novel in structure, is capable of conveniently disassembling the nuts of different models without replacing socket heads in use, and is convenient to carry.
Description
Technical field
The utility model belongs to the improvement of box spanner structure, particularly a kind of improved box spanner.
Background technology
Box spanner is commonly referred to as sleeve, and it is by the sleeve in a plurality of band hexagon rings or 12 jiaos of holes and is furnished with handle, extension bar etc.Box spanner uses boxed, and 20 one boxes of lilliput socket spanner in use need be changed corresponding sleeve according to the model of nut, and complex operation carries inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of improved box spanner, and its novel structure need not be changed collet head during use, and just the nut of dismounting different model easily is easy to carry.
The purpose of this utility model is achieved in that a kind of improved box spanner, the two ends of connecting rod affixed respectively big sleeve and small sleeve, the structure of big sleeve and small sleeve is radial open six elasticity battens for uniform setting the on the circumferential end surfaces of cylindrical shroud cylinder base outer end, on the medial surface of elasticity batten outer end, the mating surface that matches with the hex nut hex surface is being set, on the external cylindrical surface of receiver, screw thread is being set, the lock ring cover constitutes by cylindrical sleeve with conical sleeve that cylindrical sleeve is connected as a single entity, the big end of conical sleeve is outside, the inwall of cylindrical sleeve matches with receiver by screw thread and is connected, the inwall of conical sleeve matches with the lateral surface of six elasticity battens, the mating surface of affined six elasticity battens is matched with hex nut, the cross through hole that boosting-rod is installed is being set on connecting rod.
When the utility model uses, only need rotation lock ring cover, adjusts the size of sleeve hex surface of the inboard mating surface formation of six elasticity batten outer ends.Open by the elasticity of six elasticity battens during degree of tightness hoop cover, it is big that bore becomes; When tightening the lock ring cover, bore diminishes, and is enclosed within then on the nut, is convenient to the dismounting nut.The utility model novel structure need not be changed collet head during use, and just the nut of dismounting different model easily is easy to carry.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing,
Fig. 1 is a sectional structure schematic diagram of the present utility model;
Fig. 2 is the right TV structure schematic diagram of Fig. 1.
The specific embodiment
A kind of improved box spanner, as Fig. 1, shown in Figure 2, the two ends of connecting rod 1 affixed respectively big sleeve and small sleeve, the structure of big sleeve and small sleeve is radial open six elasticity battens 3 for uniform setting the on the circumferential end surfaces of cylindrical shroud cylinder base 2 outer ends, on elasticity batten 3 outer end medial surfaces, the mating surface 4 that matches with the hex nut hex surface is being set, on the external cylindrical surface of receiver 2, screw thread is being set, lock ring cover 5 constitutes by cylindrical sleeve with conical sleeve that cylindrical sleeve is connected as a single entity, the big end of conical sleeve is outside, the inwall of cylindrical sleeve matches with receiver 2 by screw thread and is connected, the inwall of conical sleeve matches with the lateral surface of six elasticity battens 3, the mating surface 4 of affined six elasticity battens 3 is matched with hex nut, the cross through hole 6 that boosting-rod is installed is being set on connecting rod 1.Elasticity batten 3 is made of spring steel or structural alloy steel.The diameter of small sleeve receiver is 0.5 times of big jacket casing cylinder base diameter.
