Abstract

The utility model discloses a novel bidirectional acting ratchet wrench, which comprises an output shaft, a driven gear, a drive gear, a planetary gear, a ratchet mechanism, a handle and end covers, wherein the handle and the drive gear are integrally welded; the end covers are arranged at the two ends of the drive gear; the driven gear is arranged at the center of the drive gear; the ratchet mechanism is arranged at the center of the driven gear; an output shaft is arranged at the center of the ratchet mechanism; the two ends of the output shaft extend out of the end covers; and the planetary gear is arranged between the drive gear and the driven gear. When the handle of the wrench is repeatedly shifted to move towards two directions, the output shaft of the wrench is rotated toward the direction which is the same as the direction of the handle, so that the wench can do work to a nut regardless of whether the wrench is rotated clockwise or anticlockwise. The bidirectional working ratchet wrench has the advantages that the bidirectional working ratchet wrench can work continuously, and enhances the work efficiency, and moreover, the bidirectional working ratchet wrench is convenient to use and simple in structure.

Description

A kind of Double-way doing-work ratchet spanner

Technical field

The utility model relates to field of tool, specifically a kind of Double-way doing-work ratchet spanner.

Background technology

The instrument that is generally used for the workpiece such as rotating nut, bolt has open-end wrench and ratchet spanner, open-end wrench in use, to just spanner need to be taken off from workpiece behind less corner of workpiece rotation, and then spanner is changed angle be placed on the workpiece and be rotated further, this process will be repeated repeatedly usually, until workpiece is tightened fully or unclamps, use inconvenient; Ratchet spanner is closed device normally, ratchet spanner in use, one has a try, and to only have a direction be effectively to do work, the motion of another one direction is without any effect fully, has so just reduced operating efficiency.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of easy to use, and is simple in structure, and the two-way work doing ratchet spanner that can increase work efficiency.

The utility model is achieved through the following technical solutions: a kind of Double-way doing-work ratchet spanner, comprise output shaft, driven gear, driving gear, planetary gear, ratchet mechanism, handle and end cap, and described handle and driving gear are welded as a whole; Described end cap is installed in the driving gear two ends; Described driven gear is installed in the driving gear center; Described ratchet mechanism is installed in the driven gear center; Described output shaft is arranged on the ratchet mechanism center, and end cap is stretched out at two ends; Described planetary gear is installed between driving gear and the driven gear.

As preferably, described planetary gear has four, and is distributed on the circumference between driving gear and the driven gear.

As preferably, described driving gear, driven gear and planetary modulus equate.

As preferably, described driving gear is ring gear.

The beneficial effects of the utility model are: pinch bar is both direction when motion back and forth, can realize that the spanner output shaft rotates to same direction, thereby no matter reached spanner still rotates counterclockwise clockwise, can both do work to nut, but continuous operation, easy to use, simple in structure, greatly improved the efficient of work.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is the front view of two-way work doing ratchet spanner of the present utility model;

Fig. 2 is the left view of two-way work doing ratchet spanner of the present utility model;

Fig. 3 is the schematic diagram of A-A direction shown in Figure 2;

Fig. 4 is the schematic diagram of B-B direction shown in Figure 2;

Fig. 5 is the schematic diagram of ratchet structure in the utility model two-way work doing ratchet spanner.

The specific embodiment

To shown in Figure 5, a kind of Double-way doing-work ratchet spanner of the present utility model comprises output shaft 1, driven gear 2, driving gear 3, planetary gear 4, ratchet mechanism 5, handle 6 and end cap 7 such as Fig. 1, and described handle 1 is welded as a whole with driving gear 3; Described end cap 7 is installed in driving gear 3 two ends; Described driven gear 2 is installed in driving gear 3 centers; Described ratchet mechanism 5 is installed in driven gear 2 centers; Described output shaft 1 is arranged on ratchet mechanism 5 centers, and end cap 7 is stretched out at two ends; Described planetary gear 4 is installed between driving gear 3 and the driven gear 2.

Wherein, described planetary gear 4 has four, and is distributed on the circumference between driving gear 3 and the driven gear 2; The modulus of described driving gear 3, driven gear 2 and planetary gear 4 equates; Described driving gear 3 is ring gear.

When handle clockwise rotated, ratchet mechanism 4 played single effect, and the output shaft 1 in end cap 7 left sides clockwise rotates; When handle 6 rotates counterclockwise, and the active internal gear 3 that handle 6 is fixed together rotates counterclockwise simultaneously, drives four planetary gears and rotates counterclockwise, and four planetary gears 4 drive driven gears 2 and clockwise rotate, and the output shaft 1 in end cap 7 left sides is exported clockwise.

The changed course of gear output is to realize by left and right output shaft shown in Figure 1, for example can set the left side and be output as clockwise, and the right side is exactly counterclockwise so.

The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
