Description

Dismountable ratchet spanner

Technical field:

The utility model relates to the hand-operated tools technical field, refers in particular to dismountable ratchet spanner.

Background technology:

In mechanical processing industry, ratchet spanner is very common hand-operated tools, it utilizes the engagement of ratchet and pawl teeth to realize directed dismounting and installation to securing member, the ratchet spanner of this structure includes the handle body, ratchet, ratchet and jump ring, the turn-knob that commutates in addition of band commutation function, spring and Spring Card cap, one end of handle body is provided with twists the open-end wrench that bolt or nut are used, the other end is provided with two-way ratchet, jump ring is that ratchet and handle body are located mutually, the commutation turn-knob, the engagement direction of spring and Spring Card cap control ratchet and ratchet, ratchet is stuck on the threaded connector that is screwed or unscrew with the internal tooth of quincuncial arrangement, the rotating handle body can screw or unscrew threaded connector, its weak point is: the one, after the existing ratchet spanner assembling, dismounting all can not be dismantled or be difficult to each accessory, if meet individual component damage or damage in the process of using, entire product all will be scrapped, and cause the great wasting of resources; The 2nd, spring causes ratchet and ratchet contact-making surface discontinuity in half-moon-shaped groove inclined hole, and the performance of product is descended.

Summary of the invention:

The purpose of this utility model provides that a kind of serviceability is good, dismountable ratchet spanner of replaceable accessory.

The purpose of this utility model is achieved in that dismountable ratchet spanner, include handle body, ratchet, ratchet and jump ring, promising ratchet is installed in the ratchet installation position of handle body, one side of ratchet is provided with jump ring, ratchet to the ratchet in the jump ring direction jump ring outside is provided with the rosette installation position, and the rosette spacing to jump ring is installed in the rosette installation position.

Above-mentioned ratchet spanner is one-way ratchet wrench or reversible ratcheting tool or the ratchet spanner that does not have commutation.

When above-mentioned ratchet spanner is one-way ratchet wrench, be provided with the spring locating piece in the spring installation position of ratchet spanner, an end of spring is supported on the ratchet, and the other end is socketed on the spring base.

The outer surface of above-mentioned rosette is provided with the annular convex ring that clamping is used, and the inner surface of the rosette installation position on the ratchet is provided with the annular groove that matches and locate with annular convex ring.

Above-mentioned rosette is made with resilient plastic material.

The external diameter of the external diameter＞rosette of above-mentioned jump ring, the external diameter of the external diameter 〉=ratchet of described jump ring.

The outstanding compared to existing technology advantage of the utility model is:

1, make with resilient plastic material owing to rosette of the present utility model, so, after indivedual accessories damage, can pull down rosette earlier, pull down snap ring, ratchet and commutation accessory again, change to assemble behind the accessory that damages and get final product, make the accessory that not have damage can continue use;

2, since spring locating piece of the present utility model can to guarantee ratchet and ratchet contact-making surface stressed even, make the stable performance of product;

3, simple in structure, replacing convenience of the present utility model economizes on resources.

Description of drawings:

Fig. 1 is a partial sectional view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is a decomposing schematic representation of the present utility model;

Fig. 4 is the schematic perspective view of spring base of the present utility model.

The specific embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-4:

Dismountable ratchet spanner, include handle body 1, ratchet 5, ratchet 2 and jump ring 4, in the ratchet installation position 13 of handle body 1 promising ratchet 5 is installed, one side of ratchet 5 is provided with jump ring 4, ratchet 5 to the ratchet 5 in jump ring 4 direction jump rings 4 outsides is provided with rosette installation position 11, and the rosette 6 spacing to jump ring 4 is installed in the rosette installation position 11.

Above-mentioned ratchet spanner is one-way ratchet wrench (Fig. 1-3) or reversible ratcheting tool or the ratchet spanner that does not have commutation.

When above-mentioned ratchet spanner is one-way ratchet wrench, be provided with spring locating piece 8 in the spring installation position of ratchet spanner (semilune groove) 7, an end of spring 3 is supported on the ratchet 2, and the other end is socketed on the card 81 of spring base 8.

The outer surface of above-mentioned rosette 6 is provided with the annular convex ring 61 that clamping is used, and the inner surface of the rosette installation position 11 on the ratchet 5 is provided with the annular groove 111 that matches and locate with annular convex ring 61.

The above-mentioned resilient plastic material of rosette 6 usefulness is made.

The external diameter of the external diameter＞rosette 6 of above-mentioned jump ring 4, but because jump ring 4 necking downs during dismounting, take out in 12 from the jump ring installation position or pack into, and the external diameter of the external diameter 〉=ratchet 5 of described jump ring 4 is so that carry out dismounting to ratchet 5.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
