The said connecting rod has a polygonal match axle with match surface at its one end and a socket at its anothe end. The said match surface has a steel ball and the inner surface of said socket has a recess for recepting said steel ball. The said match axle has a smell neck for connecting to said socket via a guide edge.
Description
Technical field
The present invention relates to a kind of rotatable continuing pole, refers to a kind of the linking in the lever handle of hand-held tool and the bearing rod between the tool heads especially.
Background technology
The use of instrument of being spirally connected is one of indispensable hand-held tool for now industry development, the use of its type structure is along with the progress in epoch and the difference of demand change to some extent, wherein, the use of hex bolts head promptly is an example, by known techniques as can be known, the use of general hex bolts head, it is the bolt head use that is hexagon with an axostylus axostyle socket ora terminalis that is Hexagonal jacket, yet, employed axostylus axostyle all has fixed dimension, pattern, and bolt head is used in the situation of different places for convenience, its kenel is also slightly different, please referring to Fig. 1, shown in Figure 2, wherein, hand-held tool bar portion 50 shown in Figure 1 is elastomeric member, be characterized in that this bar portion 50 can be the bending of wide-angle, and be suitable for position place's interior location or remote region and can't be with the spiral shell spare of linear fashion and its swivel nut, yet, because the rigidity deficiency of its bar portion 50, for the tighter spiral shell spare of the solid situation of spiral shell smoothly the spiral shell pine maybe can't reach the effect of complete locking screw spare, reality is not had a utilization benefit.
And Figure 2 shows that a kind of above-mentioned universal extension bar of commonly using disappearance that improves, be characterized in that this bar portion 60 can have a preferable rigidity and can rotate any angle, yet, because this extension bar is behind the socket certain-length, being difficult for keeping firm length directly spends, not only not easy to operate and efficient that use is also not satisfactory in the moving spiral shell spare of spiral shell, the necessity that is improved is arranged in fact.
Summary of the invention
In order to improve the above-mentioned extension bar of commonly using in serial connection, inconvenience when spiral shell is established, main purpose of the present invention is to provide a kind of rotatable continuing pole, it is simple in structure, more convenient when socket or spiral shell are established, practical, can be suitable for the general linearly spiral shell spare of contact on not only using, establish for spiral shell that the position must tilt or the spiral shell spare of translation-angle, still can stablize, operation smoothly, to save time and efficient.
Based on above-mentioned purpose, technological means of the present invention is to provide a kind of rotatable continuing pole, a wherein end of this bearing rod forms a socket part, the other end then forms less the pulling of outer peripheral edges and connects axle, the lateral surface that connects axle of pulling is convexly equipped with a steel ball body, pull and connect axle and be a cerioid, connect the face of setting that an outer rim forms arc shape in pulling, set this end of the contiguous socket part of face and bring the neck that is outer peripheral edges together, and neck is connected with the socket part with the bigger guide lug portion of outer peripheral edges again, and forming a guide lug portion in face of setting and joint, socket part, this guide lug portion periphery can not be less than the trepanning inner peripheral;
Be arranged with a trepanning and be located at the socket part end face axial of accepting rod end, the trepanning inner edge is slightly larger than to pull and connects an outer peripheral edges, is concaved with groove in trepanning inner edge wall, and this groove to the distance of trepanning ora terminalis is to pull to connect the distance of the steel ball body of axle to neck.
Implement after the technological means of the invention described above, when the present invention need make hand-held tool can be an angle beat, two adjacent bearing rods are connected in series mutually, and make and pull when connecing steel ball body on the axle and being embedded in the groove, can be the deflection of a certain angle between two bearing rods;
When needs are the direct rod shape linking with hand-held tool, then will be fixed in the trepanning ora terminalis with guide lug body cover between two bearing rods again, then can affixed one-tenth direct rod shape.

The specific embodiment
Further specify architectural feature of the present invention and purpose below in conjunction with accompanying drawing.
See also Fig. 3~Figure 10, the various embodiments structure of selecting for use for the present invention shown in the figure, this only for explanation, is not subjected to the restriction of this kind structure in patent application.
At first see also Fig. 3~shown in Figure 6, the present invention's " rotatable continuing pole ", its mainly be connected in the lever of hand-held tool 1 and tool heads 4 between bearing rod 2, wherein, this lever can be for gripping for the portion of holding 11 1 one ends, and end is socket part 12 in addition, and it is nested to connect axle 21 for pulling of bearing rod 2 one ends, the suitable place of its inner rim wall is formed with the chase 121 of predetermined number, by chance can connect the axle 21 steel ball bodies 3 that are convexly equipped with for pulling and be embedded.
And be located at bearing rod 22 in addition trepanning 221 inner edges of the socket part 22 of end be to be to connect the designs that axle 21 is planted for pulling, then be concaved with in trepanning 221 inner edge walls and connect axle 21 grooves of setting 222 for pulling, this groove 222 to the distance of trepanning 221 ora terminalis is about to pull and connects the distance of the steel ball body 3 of axle 21 to neck 210.
When the length that will prolong hand-held tool, and when making hand-held tool can be a certain angle beat, with bearing rod 2 ' connect to pull as illustrated in fig. 6 axle 21 ' with adjacent bearing rod 2 trepannings 221 sockets, connect when pulling axle 21 ' steel ball body 3 be embedded in the groove 222 of depression after, connect owing to pull on the free end face of the less neck 210 ' trepanning 221 of axle 21 ' outer peripheral edges, making pulls connect the axle 21 ' can be the beat of a certain angle, and when the predetermined length of most bearing rods 2 sockets one, can be curved pendulum (as shown in Figure 8) by a relatively large margin.
Again when bearing rod 2 after socket, when desiring to keep fixed length and directly spending, then must connect pulling axle 21 guide lug portion 212 be pressure bonded to as illustrated in fig. 5 another bearing rod 2 ' socket part 22 ' trepanning 221 ' ora terminalis, make two-phase serial connection bearing rod 2,2 ' between can't swing mutually, at this moment, 3 of the steel ball bodies that being positioned at pulls connects on the axle 21 stay on socket part 22 ' inboard perisporium admittedly, form a fixing extension bar kenel (shown in Fig. 5,7).
Moreover, bearing rod 2 feature kenels of the present invention can also be suitable for universal extension bar (as shown in Figure 9), the operation that the screw terminal extension rod is used has more practicality, and Figure 10 shows that the present invention can be concealed in the bearing rod after the socket 2 embodiment of shank part 11 inside, with the extension or the contraction that can make things convenient for bearing rod 2, and have more practical value.
The announcement of the above embodiment is in order to explanation the present invention, is not that the displacement of the change of numerical value or equivalence element such as is still for being subordinate to category of the present invention in order to restriction the present invention.
