Abstract

The utility model relates to a multipurpose double offset ring spanner with a sleeve barrel. The utility model is mainly composed of a handle, a double offset ring spanner head, a rotary reversing device, the sleeve barrel, and a sleeve rod, wherein, a rotary reversing switch which is arranged in an inner cavity on a connecting position of the handle and the double offset ring spanner head can be used for controlling the positive rotation of the double offset ring spanner head or the reverse rotation of the double offset ring spanner head; the double offset ring spanner head and a tooth locking device which is arranged on the sleeve barrel are in locking connection, and tooth locking device is matched with the handle for having the functions of a socket spanner; the handle and the double offset ring spanner head are movably connected through a clamping spring and a positioning slot, and double offset ring spanner heads with different specifications can be arranged in the inner cavity on one head of the handle. The utility model has the advantages of convenient use, portability, and reduced weight.

Description

A kind of sleeve double offset ring spanner

The utility model relates to a kind of sleeve double offset ring spanner of hardware ﹠ tools class.

Current, the double offset ring spanner that people use, the function of box spanner one class instrument is single substantially, to repeat in the use to come and go and be inserted in the bolt rotation, and the bolt of different size is wanted corresponding specification double offset ring spanner of adapted or sleeve, therefore, its defective is, function singleness, service efficiency is low, carries inconvenience.

At the weak point that existing double offset ring spanner exists, the utility model design provides a kind of combined sleeve double offset ring spanner, and has a kind of sleeve double offset ring spanner of forward and backward rotation function.

The technology side that realizes above-mentioned purpose is described below: it includes the rotation reversing arrangement, handle, the plum blossom spanner, collet head and loop bar four partly combine, the plum blossom spanner is connected with the jump ring geocoded activity with locating slot with handle, be provided with the rotation reversing arrangement at their contact inner chambers of handle at location place, it includes the location slightly, subscript pin, spring and thumb wheel, thumb wheel and subscript pin cotter way flexibly connect, the handle upper end is the garden body of cavity opening, and the upper end is connected with bush whorl, and sleeve is provided with lock tooth device, it is made up of locking bar and stage clip, and locking connects the plum blossom spanner.

The good effect that the utility model produced is: rotate reversing arrangement and change gyrobearing (180 °), can control the plum blossom spanner forward or backward rotation, have easy to use and improve the advantage of power.The cavity of handle can be placed one group for the plum blossom spanner that uses, and is easy to carry.Sleeve and handle are connected, and are provided with lock tooth device, are used with the plum blossom spanner, have the impact wrench double-purpose functional, reach the effect that a tool is used more.

Below, with reference to the accompanying drawings, description in conjunction with the embodiments is described in detail the utility model technology contents.

Fig. 1 is this utility structure view.

Fig. 2 is the tube-in-tube structure view.

Fig. 3 is a plum blossom spanner contour structures view.

Shown in Figure 1, the left end garden annular of handle 7, interior aperture apparatus has jump ring, connect with the upper end of the excircle of plum blossom spanner 1 or the locating slot 10 location assemblings of lower end, but according to the plum blossom spanner that uses needs attaching different size, in the garden shape inner chamber that handle 7 ends communicate with endoporus, be provided with the rotation reversing arrangement, alignment pin 5 upper end top pressure springs 6, the lower end is that the inclined plane contacts with one inclined-plane, two symmetrical inclined-planes of subscript pin 3 upper ends is movable; Thumb wheel 4 is fitted in the translot of offering the handle 7 vertical with garden shape inner chamber, the outer handle 7 that is exposed at of part, it and subscript pin 3 cotter ways flexibly connect, subscript pin 3 upper ends are provided with two inclined-planes along the central axis declivity, the lower end is an inclined plane, be shaped on little elongated slot on the subscript pin 3, carry out the groove pin with the lateral pin on the thumb wheel and flexibly connect; Thumb wheel 4 Rotate 180s ° make subscript pin 3 rotate 180 °, the pinnacle conversion rightabout on inclined plane, and the aperture 2 of roof pressure plum blossom spanner 1 as shown in Figure 3, has been realized that plum blossom spanner 1 is clockwise and has been reversed.The other end of handle 7 is garden bodies of opening garden shape inner chamber, and the upper end is threaded with sleeve 13 (loam cake), can place the plum blossom spanner 8 of different size and the spanner 9 and the loop bar 10 of an interior hexagonal in the inner chamber, and their endoporus is worn the loop bar 10 of ining succession.One of loop bar 10 with sleeve 13 screw threads or fastener connection.Sleeve 13 lower ends are provided with the garden shape shrinkage pool that cooperates with plum blossom spanner 1.Be provided with one group of pin tooth device in the circumference side, cooperate location plum blossom spanner 1 with the aperture on plum blossom spanner 1 circumference 2, be movably connected on the sleeve 13 with bolt in the middle of the pin tooth 11, the upper end connects with stage clip 12 tops, there is crotch roof pressure aperture 2 lower end, location plum blossom spanner 1, and loop bar 10 upper ends connect with interior hexagonal spanner 9 hexagonals cover, connect at the locating slot 14 of interior hexagonal spanner 9 jump ring draw-in groove, have the sleeve function of use with handle 7 left end endoporus.
