Further, the length of described mobile jib is greater than the length in described backstay portion.
Further, the section area of described mobile jib on this mobile jib axis direction is less than 1/2nd of the section area of described backstay portion on this mobile jib axis direction.
Further, described second hole is between described first hole and described second chuck.
Further, be fixed by bolt and nut between described web member and described movable device.
Further, the length of described first jig arm is less than the length of described second jig arm.
Further, described second jig arm is also formed with multiple perforation, described pilot hole is between described perforation and described second chuck.
Further, described mobile jib and described backstay portion are cylindric.
Further, described first hole and described second hole are circular hole.
Compared with prior art, the beneficial effect that the utility model possesses is: electroplating clamp of the present utility model has the locating mechanism be connected between the first jig arm and the second jig arm, this locating mechanism in order to realize the normally open of two jig arm, thus is convenient to the cleaning at chuck position, time saving and energy saving.

Embodiment
Below with reference to embodiment shown in the drawings, the utility model is described in detail.
Shown in Fig. 4, in the utility model embodiment, a kind of electroplating clamp, comprises the first jig arm 1, second jig arm 2, is connected to elastic reset part 4 between described first jig arm 1 and the second jig arm 2 and pivot cuff link 3 and locating mechanism 5.Described first jig arm 1 have lay respectively at this first jig arm 1 length direction on first chuck 10 at both ends and movable device 11, described second jig arm 2 have lay respectively at this second jig arm 2 length direction on second chuck 20 at both ends and pilot hole 21.Wherein, pivot cuff link 3 in order to the first jig arm 1, second jig arm 2 to be carried out connecting and to allow both with this pivot cuff link 3 for fulcrum rotates, and is provided with spring, in order to the reset force providing two jig arm to open in elastic reset part 4.
In present embodiment, described locating mechanism 5 comprises mobile jib 51, backstay portion 52 and web member 53, described backstay portion 52 is located at described mobile jib 51 one end away from the first jig arm 1, described web member 53 is located at described mobile jib 51 one end near the first jig arm 1, and described web member 53 fixes with described movable device 11.Particularly, movable device 11 comprises two portions of picking up the ears extended to form towards the second jig arm from the first jig arm 1, being provided with one in this portion of picking up the ears can free rolling roller part, described web member 53 is by this roller part of bolt and nut mode, thus guarantee two jig arm open or closed action time, the extension mode in mobile jib 51 and backstay portion 52 can do adaptive change.
Continue with reference to Fig. 2, shown in Fig. 3 and Fig. 4, in present embodiment, described locating mechanism 5 is placed through in described pilot hole 21 at least partly, described pilot hole 21 comprises the first hole 211 and the second hole 212 be interconnected, the port area in described first hole 211 is greater than the port area in described second hole 212, the section area of described backstay portion 52 on the axis direction of described mobile jib 51 is less than the port area in the first hole 211 and is greater than the port area in the second hole 212, the section area of described mobile jib 51 on the axis direction of described mobile jib 51 is less than the port area in the second hole 212.Thus when needs cleaning chuck, only two jig arm need be drawn close, in this process, backstay portion 52 is protruding, and when being in the first hole 211 completely and being outside, automatically drop in the second hole 212, because the port area in the second hole 212 is less than the section area in backstay portion 52, thus the location in this backstay portion 52 can be realized, two chucks are in normally open.
For realizing the utility model better, preferably, the length of described mobile jib 51 is greater than the length in described backstay portion 52.The section area of described mobile jib 51 on this mobile jib axis direction is less than 1/2nd of the section area of described backstay portion 52 on this mobile jib axis direction.Described second hole 212 between described first hole 211 and described second chuck 20, thus can guarantee to stir without the need to external force, and this locating mechanism can realize location automatically.Further, the length of described first jig arm 1 is less than the length of described second jig arm 2.Described second jig arm 2 is also formed with multiple perforation 24,25, and described pilot hole 21 is between described perforation 24,25 and described second chuck 20, and it plays the effect of loss of weight.It is worth mentioning that, in the utility model embodiment, described mobile jib 51 and described backstay portion 52 are in cylindric, and described first hole 211 and described second hole 212 are in circular hole, and other shapes also can realize certainly.
In sum, the beneficial effect that the utility model possesses is: electroplating clamp of the present utility model has the locating mechanism be connected between the first jig arm and the second jig arm, this locating mechanism in order to realize the normally open of two jig arm, thus is convenient to the cleaning at chuck position, time saving and energy saving.
Be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should by specification sheets integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
