Abstract

The utility model discloses a quick fastening F shaped tool clamp comprising a bent bracket clamp body (1) and a moving clamp (2) with one end slidably-connected on the bent bracket clamp. The improvement lies in that a floating clamp mouth(3) and a clamping lever (5) are rotationally connected with an upper portion and a lower portion of the other end of the moving clamp (2) separately, and the floating clamp mouth (3) is corresponded with a clamp mouth of the bent bracket clamp body (1), then an elastic gear-pawl (4) which is rotationally arranged in the clamping lever (5) is toothed and positioningly connected with a locking rack arranged on the moving clamp (2). During the process of construction, the elastic gear-pawl (4) which is arranged on the clamping lever is anchored by the clamping lever (5) which is rotationally connected with the end portion of the moving clamp (2) and is movingly mouthed and positioned along the locking rack on the moving clamp, thereby the quick fastening and processing of the work-piece are achieved, the work efficiency is improved and strength of clamping the work-piece is strong and firm.

Description

The F shape instrument folder of quick-fastening

(1) technical field: the utility model relates to Workpiece clamping device; Be specifically related to a kind of F shape instrument folder of quick-fastening.

(2) background technology: machinery manufacturing industry of the prior art, be generally used for two or more clamp between multiplex's part processing (as clamp welding, boring, bolt connect tighten up, riveted joint etc.) F shape instrument folder, its structure is by elbow shape retaining clip and end slip company movable clamp thereon, and is provided with the clamping screw formation in described movable clamp the other end.In construction operation, it exists not enough: the one, and manual rotary screw clamping work pieces speed is slow, has reduced operating efficiency; The 2nd, it is little and easily make workpiece loosening that clamping screw tightens up power, influenced the solid and reliable property that workpiece clamps processing.

(3) summary of the invention: the purpose of this utility model is to provide a kind of F shape instrument folder that can quick-fastening, be intended to improve workpiece and clamp operating efficiency, and it is big and solid and reliable clamping work pieces to tighten up power.

For achieving the above object, the F shape instrument of the utility model quick-fastening folder technical scheme is achieved in that and comprises that elbow shape retaining clip and end slip connect movable clamp thereon; Its improvement is: at the upper and lower of the described movable clamp other end, be rotatably connected with respectively and float the folder mouth and tighten up handle; Described unsteady folder mouth is corresponding with the folder mouth of elbow shape retaining clip; Tighten up in the handle described, rotate the elastic claw that is provided with, the locking rack engagement location that is provided with described movable clamp joins.

The utility model is taked said structure, in construction operation, be connected in the handle that tightens up of live splint end of body by rotation, the company's of drive elastic claw thereon, move, mesh the location along the locking rack on the movable clamp, realized workpiece quick-fastening processing, improved operating efficiency and clamping work pieces power is big, solid and reliable.

(4) description of drawings: Fig. 1 has the front view of part section for the utility model.

(5) specific embodiment: shown in Figure 1.The F shape instrument folder of the utility model quick-fastening comprises that the slip of an elbow shape retaining clip 1 and an end connects movable clamp 2 thereon; At the upper and lower of described movable clamp 1 other end, be rotatably connected with respectively and float folder mouth 3 and tighten up handle 5; Described unsteady folder mouth 3 is corresponding with the folder mouth of elbow shape retaining clip 1; Tighten up in the handle 5 described, rotate the elastic claw 4 that is provided with, locate join (shown in Figure 1) with the semicircle shape locking rack engagement that described movable clamp 2 is provided with.Certainly, locking rack also can be set as the inclined plane shape (not shown).In the construction operation, need involutory joining when welding as two workpiece on the hull, the folder mouth of the utility model elbow shape retaining clip 1 is clamped two workpiece earlier with the folder mouth 3 that floats, move and tighten up handle 5 and make the elastic claw 4 that rotate to connect thereon, the semicircle shape tooth bar that is provided with along movable clamp 2, move (Fig. 1 be move to left direction) to tooth depth end place by tooth by the tooth low side, this moment, elastic claw 4 was under the effect of spring force, all the time with the semicircle shape tooth bar on each tooth engagement location join, until the folder mouth by elbow shape retaining clip 1 and the folder mouthfuls 3 that floats fast with the fastening jail of workpiece clamp.Treat that two workpiece welding processing finish, hand is pressed elastic claw 4 and is overcome the locking rack that spring force makes its hock disengaging be meshed and locate, move simultaneously and tighten up handle 5 and drive hock 4, move to right, will tighten up workpiece and unclamp to the tooth lower end engagement location (with reference to shown in Figure 1) of semicircle shape tooth bar.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characterictic that the process creative work just can be associated; can also make some modification and improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
