Fig. 2 is A-A view of the utility model embodiment based on Fig. 1 curved rod device provided；

Fig. 3 is B-B view of the utility model embodiment based on Fig. 1 curved rod device provided.

As shown in Figure 1-3, curved rod device provided in this embodiment, comprising: the first hand holding handle 3 and the second hand holding handle 2, described One hand holding handle 3 and 2 head of the second hand holding handle are provided with bending component；First hand holding handle 3 and described second is held Handle 2 is connected by the first fixing axle 10, and the bending structure 8 being used cooperatively with the bending component is arranged in the fixing axle； It is also connected with link mechanism on the bending component of first hand holding handle 3, is provided on the link mechanism and is passed through for pitman Through-hole, link mechanism does the adjustment of arbitrary orientation for pitman.

It should be noted that curved rod device further includes adjusting knob 1, for adjusting first hand holding handle 3 and described second The rotation angle of hand holding handle 2；And first hand holding handle 3 is connected by first fixing axle and second hand holding handle 2 rotation It connects；The use of first hand holding handle 3 and second hand holding handle 2 can be facilitated.

It should also be noted that, the outer wall of bending structure 8 is provided with the first recessed portion, and the radian of the first recessed portion and company The radian taken over the baton is adapted, the convenient bending to pitman.

In the present embodiment optinal plan, the link mechanism includes first connecting rod 5 and second connecting rod 7, the first connecting rod 5 It is rotatablely connected with the second connecting rod 7 by the first connector 6；Wherein the first connector 6 is set as screw, when first company After the position of bar 5 and the second connecting rod 7 is adjusted, screw-driving can be fixed link mechanism.

It should be noted that the first connector 6 can be set to screw, it may be set to be other connectors, as long as energy It is enough that first connecting rod 5 and second connecting rod 7 is fixed, therefore no longer illustrate one by one here.

Specifically, one end on the first connecting rod 5 far from the second connecting rod 7 is additionally provided with retaining mechanism 4, first connects Bar 5 is rotatablely connected by retaining mechanism and the second connector, is provided with the through-hole on the retaining mechanism 4；Company can be facilitated It takes over the baton across and then capable of doing to pitman and adjust at any angle.

Further, the retaining mechanism 4 includes locking member 18, bayonet lock 17 and the pressure ram for being press-connected stick, institute The outer cover for stating pressure ram is equipped with the first elastic component 15, and the bayonet lock 17 is set as oblique with what the locking member 18 contacted on one side Face.

It should be noted that locking member 18 is screwed down during being fastenedly connected stick, due to bayonet lock 17 and locking member 18 contacts are set as inclined-plane on one side, so bayonet lock 17 is to the side for being provided with pressure ram during locking member 18 moves down It is mobile, therefore pressure ram continues to move to be press-connected stick, can fix pitman；Simultaneously because the first elastic component 15 is set Set, after unclamping locking member 18, under the action of the first elastic component 15, bayonet lock 17 can automatic rebounding, therefore use is very square Just.

It should also be noted that, the first elastic component 15 can be set to spring, it may be set to be other elastic constructions, only It wants that elastic effect can be played, therefore no longer illustrates one by one here.

Further, the retaining mechanism 4 further includes pin 16, the groove of the pin 16 and 17 bottom of bayonet lock It is used cooperatively, for limiting.

It should be noted that since the setting of 17 bottom of bayonet lock is fluted, it is mobile to the side of pressure ram in bayonet lock 17 When, bayonet lock 17 can be limited by pin 16 and the cooperation of groove.

It should also be noted that, the retaining mechanism 4 further includes the second connector 14, the retaining mechanism 4 passes through described Second connector 14 is connect with the second connecting rod 7.

It should also be noted that, since one end that second connecting rod 7 is connect with locking mechanism is provided with screw, and second connects Part 14 is set as nut again, so after the position of the first connecting rod 5 and the second connecting rod 7 is adjusted, by nut and spiral shell Nail is tightened, and then locking mechanism and second connecting rod 7 is fixed.

In the present embodiment optinal plan, the bending component includes bending idle wheel 12 and the second fixing axle 11, the bending Idle wheel 12 is used cooperatively with the bending structure 8；First hand holding handle 3 and second hand holding handle 2 and described second are fixed Axis 11 connects.

Specifically, being provided with the second elastic component 13 above the bending structure 8, second elastic component 13 is set in described Outside first fixing axle 10.

Further, the bending structure 8 is connect by positioning pin 9 with first hand holding handle 3.

It should be noted that the outer wall of bending idle wheel 12 is provided with the second recessed portion, and recessed to the axle center of bending idle wheel 12 It falls into, and the radian of the second recessed portion is adapted with the radian of pitman, the convenient bending to pitman.

In conjunction with can be seen that curved rod device provided in this embodiment, including first to the detailed description of the utility model above Hand holding handle 3 and the second hand holding handle 2, first hand holding handle 3 and 2 head of the second hand holding handle are provided with bending component；Institute The first hand holding handle 3 and second hand holding handle 2 is stated to connect by the first fixing axle 10, be arranged in the fixing axle with it is described curved The bending structure 8 that foldable assembly is used cooperatively；Link mechanism, the company are also connected on the bending component of first hand holding handle 3 The through-hole passed through for pitman is provided on linkage, link mechanism does the adjustment of arbitrary orientation for pitman.In use, will Pitman is put between bending structure 8 and two bending components, is bent to pitman, simultaneously because link mechanism is set It sets, pitman passes through the through-hole on link mechanism, and by adjusting link mechanism, the adjustment of any direction can be done to pitman. Therefore the pitman after solving the problems, such as bending in the prior art is easy to appear deviation.Simultaneously because link mechanism includes first Connecting rod 5 and second connecting rod 7, and one end on first connecting rod 5 far from second connecting rod 7 is additionally provided with retaining mechanism 4, retaining mechanism 4 On be provided with facilitate pitman pass through through-hole；Retaining mechanism 4 includes locking member 18, bayonet lock 17 and the extruding for being press-connected stick The outer cover of bar, pressure ram is equipped with the first elastic component 15, and bayonet lock 17 is set as inclined-plane with what locking member 18 contacted on one side.Therefore exist During being fastenedly connected stick, locking member 18 is screwed down, since bayonet lock 17 is set as inclined-plane with what locking member 18 contacted on one side, So bayonet lock 17 is mobile to the side for being provided with pressure ram during locking member 18 moves down, therefore pressure ram continues to move to It is press-connected stick, pitman can be fixed；Simultaneously because the setting of the first elastic component 15, after unclamping locking member 18, Under the action of one elastic component 15, bayonet lock 17 can automatic rebounding, therefore use is also very convenient；Therefore the present embodiment also has solid Determine the good advantage of effect.
