The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-Fig. 4; The clamping tool of convertible pincers handle angle; Comprise working head 1, pincers handle 2 and connect working head and the governor motion 3 of pincers handle; Said working head is to be connected and composed through cover plate 1-2 and locating shaft 1-3 by binding clip 1-1, and removable mouthful of mould 1-4 is housed on binding clip, and said pincers handle 2 comprises that left side pincers handle 2-1 and right pincers handle 2-2 constitute.Ratchet-type stepping mechanism 4 and pincers handle angle-adjusting mechanism 5 are housed on the said pincers handle, and said right side pincers handle 2-2 comprises top pincers handle 2-2a and clamps handle 2-2b through the rotating shaft 6 and the bottom of its flexible connection.Said ratchet-type stepping mechanism 4 comprises: be installed in the sour jujube plate 4-2 on the pincers handle 2-2a of right pincers handle top and be installed in the ratchet 4-1 on the pincers handle of a left side.On said right pincers handle, pincers handle angle-adjusting mechanism 5 is installed.Said pincers handle angle-adjusting mechanism comprises: slide block 5-1, guiding bearing pin 5-2, compression spring 5-3 and be used for the alignment pin 5-4 of the leading angle adjustment of right pincers handle; Said slide block is arranged in the U type groove of right pincers handle bottom pincers handle; Flexibly connect through guiding bearing pin and bottom pincers handle; Said alignment pin is installed on the pincers handle of right pincers handle top, and said compression spring one end is connected with slide block, and the other end is connected with right pincers handle bottom pincers handle through bearing pin 7.
Said slide block 5-1 is right pincers handle with the type shape and be installed in the right pincers handle; Be shaped on the slide block and be used for its gathering sill 5-1a in guiding bearing pin effect lower slider; Bottom, slide block outer end is shaped on the regulating handle 5-1b that suitable staff is pulled, and slide block top is shaped on the groove 5-1c of being convenient to adjust right pincers handle angle.
The lower end of said right pincers handle top pincers handle is processed and is prevented to clamp the retaining turn of bilge 2-3 that handle opened wide-angle.
The side of said right pincers handle bottom pincers handle is shaped on the arc groove 2-4 that the bearing pin of avoiding leading produces active force, and the pincers handle is shaped on outside bending part in said right pincers handle bottom.
The operation principle of the utility model is:
See also Fig. 2, Fig. 3 and Fig. 4, when clamping tool is in the initial opening state (Fig. 2), because pincers handle 2 open angles are excessive; If there is not angle-adjusting mechanism, hold the pincers handle and need apply very big power and just can make the pincers handle closed, promote regulating handle 5-1b this moment; 5-1 is left behind with slide block; Make the contacts side surfaces of slide block disengaging and alignment pin 5-4, alignment pin just in time drops on the groove of right pincers handle and slide block, and promptly rotatable right pincers handle makes its opening angle reduce (Fig. 3).At this moment, can easily apply active force,, will clamp the handle closure through the ratchet step-by-step action to the pincers handle after the anglec of rotation.When the pincers handle is closed to two hands and will touches (Fig. 4, A position), outwards rotate right pincers handle; This moment, slide block popped up, alignment pin and slide block contacts side surfaces under the effect of compression spring 5-3; Make the pincers handle open certain angle (Fig. 4, B position) again, continue to apply active force again; Securing member 8 combines closely pipe joint 10 and tubing 9 under clamping action power, can accomplish once to connect work.This clamping tool is simple to operate, and is time saving and energy saving, improved the efficient of installation.
