Abstract
The utility model relates to a ratchet type wrench which is used for unclamping and clamping nuts for vehicles, mechanical equipment, etc. The ratchet type wrench is formed by that a movable elastic force clamp is arranged in an annular fixing clamp head. One side of the movable elastic force clamp is fixedly supported by an elastic sheet, the front end is combined with the teeth of a movable clamp head, and the rear end is arranged on the wall of a fixing clamp head. The center of the movable clamp head is a nut hole, and the upper surface and the lower surface of the fixing clamp head are tightly covered by an outer cover. When the utility model is used, the utility model can clamp tightly the nut once to be positioned, and a wrench body is rotated or pushed and pulled to unclamp or clamp the nut without repeatedly taking off the wrench, so that the problem that the wrench rotates every time at present, and the wrench is taken off to be positioned is solved. The ratchet type wrench has the advantages of convenient use, simple structure, time saving, labor saving, etc.
Description
The utility model relates to a kind of wheeled spanner, is mainly used in various vehicles, plant equipment etc. and loosens, tighten nut, belongs to the instrument class.
At present, people install and repair various vehicles, when plant equipment loosens, tighten nut, front opening or the dead mouth spanners of using more, every rotation once then need be taken off spanner, rotation again behind the rechuck nut location, just can unclamp repeatedly successively or fastening nut, so not only waste time and energy, block bad spanner slippage sometimes and damage staff and other accidents also can occur.
The purpose of this utility model is exactly for solving above-mentioned deficiency, locate for people provide a kind of nut that once tightens, and rotates or pushes away, draws and pull the wheeled spanner that body just can unclamp nut or tighten, and need not take off spanner repeatedly nut is repeatedly tightened the location.
The utility model is achieved in that fixed chuck is a ring-type, assembling movable elastic card within it on the sidewall, this elastic card is square, front end is thicker than the rear end, there is the hoary hair rear end, its side holds out against with the shell fragment that is fixed on the fixed chuck wall, and front end coincide with the tooth that is contained in the movable chuck in the fixed chuck, and rear end mortar head is contained on the fixed chuck wall in the mortar groove.Movable chuck is uniform along circle to be the saw shape tooth of projection, and coincide corresponding with movable elastic card, and the center is the six-sided nut hole, tight outside housing cover with bolt in the fixed chuck top and bottom.
The utility model has the advantages that only once to tighten nut and locate, rotate or push away, draw and pull body and just can loosen, tighten nut, easy to use, simple in structure, time saving and energy saving.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1, be the utility model assembling schematic internal view.
Fig. 2, be the utility model profile schematic diagram.
Fig. 3, be the utility model movable chuck front view.
Fig. 4, be the utility model movable chuck side view.
Fig. 5, be that the utility model I is looked schematic diagram.
