Description

The spanner adaptor

The utility model relates to a kind of spanner, particularly a kind of spanner adaptor.

Since the human own civilization, hand-held tool just occupies a tiny space, and since the screw invention, spanner just occupy most important status in the hand-held tool field, only the kind of spanner just has a variety of, combination wrench, two open-end wrench, Double ring spanner, ratchet spanner etc., with ratchet spanner: please referring to shown in Fig. 1, most ratchet wrench, because the break-in button (41) that the conversion clip turns to is located at spanner (40) front end, its distance between gripping place and break-in button (41) is longer, hereat the user in use, it need grip spanner (40) on the other hand, another hand with operation is just then being stirred break-in button (41), the counter-rotating action, though its torsion height of this kind ratchet spanner only, but rotating action, only it has a congenital big shortcoming: it is because of the internals complexity, its so " head is inevitable very big ", in the working environment in little space, can't use, because it still must cooperate sleeve to add the oversize of head, therefore in little space, especially professional user can use plum blossom ratchet spanner as shown in Figure 2, only above-mentioned spanner all has very big and can't an overcome shortcoming, it promptly is its sleeve or working substance that only can be suitable for a kind of size, it can't be applicable to the sleeve of multiple size simultaneously, so the user must not change a plum blossom ratchet spanner simultaneously in size yet, the inconvenience that reality is worked as in the use, the shortcoming that this is maximum for above-mentioned spanner and can't overcome.

The purpose of this utility model is to provide a kind of spanner adaptor, the plum blossom ratchet spanner of utilize that a head is little, the space the being saved adaptor of arranging in pairs or groups, and can be applicable to simultaneously that the different size working substance uses, has the characteristic that in little space, can operate freely on the one hand, then can be suitable for the driving of the sleeve of different size on the other hand simultaneously, quite have convenience and practicality.

The technical solution of the utility model is:

A kind of spanner adaptor comprises a wrench body, and the one end is established a head, in head and establish a rolling disc, in rolling disc and cooperate an adaptor, it is characterized in that:

This adaptor comprises a disk body, and the disk body top forms two polygonal seats, and polygonal seat top is provided with a brake block.

Described spanner adaptor is characterized in that: the C type that fastens is buckled in the middle of two polygonal seats.

Described spanner adaptor is characterized in that: be installed with a steel ball in brake block one side.

Described spanner adaptor is characterized in that: establish a perforation in the middle of this adaptor and penetrate for a steady pin.

Described spanner adaptor is characterized in that: a sheathed spring on this steady pin.

Described spanner adaptor is characterized in that: this polygonal seat is the hexagonal seat.

Advantage of the present utility model is:

(1) the spanner adaptor characteristic of the utility model is: the utility model system utilizes cooperating of a wrench body and adaptor, to be applicable to the sleeve of various different sizes, has operation effect freely in little space on the one hand, more can be applicable to the use of the sleeve of different size on the other hand simultaneously, can bring the operator design that has much industry applications in fact.

(2) the spanner adaptor of the utility model, the theory of its design tie up in: first kind of ratchet spanner structure is complicated in prior art, and head volume is big but can be suitable for the working substance of multiple size simultaneously, the second kind of double offset ring spanner with ratchet all only working substance of applicable a kind of size operated freely but volume is less, and all can't both functions furthermore, after the utility model is designed the simple wrench body of a volume minor structure and cooperated an adaptor, can have above-mentioned two kinds of functions that spanner can't have concurrently for a long time concurrently.

(3) perhaps the someone can think that the wrench body head volume of the utility model is little, it just can't reach due torque value when driving the bigger sleeve of size, in fact, when being applicable to the sleeve of large-size, can the utility model size design is slightly bigger, to be specially adapted to larger-size sleeve, so just can reach due torque value equally.

(4) the reality product of the utility model complete, and the process of its operation is quite good, and its effect that has can provide the user to be convenient to use in fact.

For to effect of the present utility model, feature and purpose can have understanding and approval further, now for a preferable embodiment and after cooperating appended graphic being illustrated in.

Fig. 1 is first kind of known ratchet spanner stereogram;

Fig. 2 is second kind of known double offset ring spanner with ratchet stereogram;

Fig. 3 is the stereogram of the utility model spanner adaptor;

Fig. 4 is the exploded view of the utility model spanner adaptor;

Fig. 5 is the profile of the utility model spanner adaptor;

Fig. 6 is the schematic diagram that the utility model spanner adaptor can cooperate with the sleeve of different size.

Now cooperate and graphic the utility model preferred embodiment be described in detail as follows:

Consult Fig. 3,4,5, the utility model spanner adaptor comprises:

One wrench body (10), these wrench body (10) one ends are provided with a head (11), and inboard and establish a rolling disc (111) in head (11), this wrench body (10) also belongs to the less plum blossom ratchet spanner of head;

One adaptor (12), this adaptor (12) comprises a disk body (120), be connected to form two hexagonal seats (121 in disk body (120) top, 122), this hexagonal seat (121,122) between and form a concave ring groove (123) and buckle (124) for being inserted in a C type, in hexagonal seat (122) top and form the brake block (125) of a polygonal, these brake block (125) one sides are established a containing hole (126) for a ccontaining steel ball (127), and the main system of this brake block (125) is used for driving the usefulness of working substance, system wears a perforation (128) in the middle of this adaptor (12), be inserted in a spring (14) back and penetrate this perforation (128) for a steady pin (13), and this steady pin (13) is fixed in the adaptor (12), establish a depressed part (131) because of steady pin (13) one ends in addition so that it penetrates perforation (128) back and peaks on this depressed part (131) for steel ball (127);

One sleeve (15) generally is cylindric, and these sleeve (15) one ends are established an engagement groove (151) and are inserted in for brake block (125).

The rolling disc (111) of adaptor (12) by wrench body (10) head (11) need only be inserted in during use, and the rolling disc (111) with a plurality of recesses is stuck on the hexagonal seat (121) of adaptor (12), disk body (120) then peaks at head (11) below, just can directly match with sleeve (15) this moment, and the user can carry out the application of force by wrench body (10) and get final product.

Consult shown in Figure 6, when the utility model desire drives the sleeve of different size, because the engagement groove (151) of each sleeve (15) is size all equally, it only is the size difference, so the user just can be inserted in the brake block (125) of wrench body (10) sleeve (15) engagement groove (151) of various different sizes, to drive sleeve (15), be to manipulate all quite square design that makes it.

The utility model makes the operator still can operate the restriction that is not subjected to the space freely in narrow space, and utilize wrench body (10) to match with an adaptor (12), not only can in small space, operate freely arbitrarily, more can be applicable to the size of the sleeve of various differences simultaneously, and then reach the characteristic of taking into account ratchet spanner and double offset ring spanner with ratchet simultaneously, be the design of a suitable tool practicality and convenience.
