Description

Wrench for pedicabs

The utility model relates to particularly a kind of Wrench for pedicabs of a kind of hardware ﹠ tools.

At present need live the tire mouth with sled of long spanner during rickshaw dress tire and bit by bit adorn toward wheel on manpower, though available fish clamp when unloading tire, it is not only time-consuming but also require great effort to operate, especially to autumn, winter rickshaw the loading, unloading tire just more difficult.A kind of bicycle loading, unloading tire combination wrench is disclosed among the Chinese patent CN2058131U.But this spanner is made up of wrench body and return portion, connect with bearing pin in the middle of it, but return portion is the screwdriver of circumference rotation.This spanner is only applicable to load and unload cycle tyre usefulness, and the rickshaw tire does not have special tool more greatly owing to pressure, and the loading, unloading tire brings inconvenience to people.

It is a kind of convenient, practical that the purpose of this utility model is to provide, the Wrench for pedicabs of fixable/dismountable manpower tire.

The purpose of this utility model realizes with following proposal: the end in wrench body is established bayonet socket, and the sled hook that uses with the spanner bayonet fittings is movably connected on the wrench body by fastener, and the reinforced rib that plays the role of positioning is established in sled hook elbow end inboard.

The flexible connection end of above-mentioned sled hook is parallel to spanner bayonet socket side, and the elbow end of sled hook is relative with the open end of spanner bayonet socket, and the bending angle of its elbow end is the obtuse angle.

During the dress tire, the spanner bayonet socket blocks the circle limit, and sled hook sled is lived cover tire on one side, can go up cover tire toward pressing down.Also can select the supplementary card hook for use during the dress tire, grab be blocked first-class hand cart tyre end earlier, so that make tire more convenient.When unloading tire, the spanner bayonet socket blocks the circle limit, pries open a part earlier and again the slip-combination pliers pincers is enclosed the limit inserting, and tire can be unloaded.

The utility model because reasonable in design, the loading and unloading tire is time saving and energy saving, especially autumn, winter operation more can embody this power car and pull practicality, characteristics easily.The inconvenience that has caused because of no special tool when the utility model has not only solved the hand cart tyre loading, unloading, and can significantly improve work efficiency.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a front view of the present utility model.
