Abstract

The utility model relates to a T-shaped ratchet spanner. The middle position of a rod body is provided with a combination part. Both sides of the combination part are respectively formed and provided with operating rods. One extension rod is penetrated through the combination part in order that a ratchet group connected to one end is arranged inside the combination part. The other end can form a non-circular driving head or an insertion sleeve end opening to insert and connect with a sleeve barrel. An adjusting rod which can be retractable is connected to the operating rods. By pulling the holding separation distance of both hands, the purposes of convenient operation and labor saving can be achieved.

Description

T type ratchet spanner

Technical field

The utility model relates to a kind of T type ratchet spanner, is meant a kind of flexible force side length especially and utilizes the T type spanner structure of the changeable orientation application of force.

Background technology

We keep in repair things, more common Wrench has open-end wrench, box socket set etc., wherein, ratchet spanner system is the head of ratchet group by an end, effort handle toward other end definite length extended constitutes, utilize the non-circular contiguous block in head bottom surface to wear group one sleeve, use cover and overlay on screw terminal or nut periphery, mostly be between the operating period and on the other hand be compressed on head and obtain the location, another holds effort handle and follows the rule of " certain to the application of force, oppositely idle running is circled round " and operate, be subject to the design of monolateral effort handle, make us produce the puzzlement that strong difficulty is executed.

Again with regard to general traditional type T type spanner, it is a single main body single specification of tool (being size) only normally, therefore, when desiring to get all the ready comparatively perfect various specification with the time to the hexagonal (hexagon)nut application of force of various different size, the user will spend a many money, so will definitely be comparatively not enough aspect economy and practicality.

Summary of the invention

Main purpose of the present utility model provides a kind of simple and labour-saving T type ratchet spanner.

To achieve these goals, the technical solution of the utility model is: a kind of T type ratchet spanner, it is characterized in that, system comprises: the centre position of the body of rod is the joint portion, both sides form action bars separately, and an extension bar passes this joint portion, make the ratchet group of a client link just can be assembled in the joint portion, this extension bar other end can form non-circular driving head or sleeve port, in order to the grafting sleeve.

Be connected with the pole of scalability on this action bars.

The specific embodiment

For making the auditor understand structure of the present utility model, advantage, details are as follows to lift a preferred embodiment now:

Fig. 1 and Fig. 2 show that the centre position of the body of rod 11 is joint portion 13, and both sides form action bars 14 separately; An extension bar 12 passes this joint portion 13, the ratchet group 15 of a client link just can be assembled in the joint portion 13, and hold the sleeve 20 of non-circular driving head 17 socket different sizes with other, and then finish the T type ratchet spanner 10 of a simple-type.

During use, dial the transdeterminations orientation that dallies surely via the knob 16 of ratchet group 15, we can know easily by the index effect of this knob 16 orientation of the reverse application of force thus, can the both hands application of force turn sleeve 20 with driving head 17.

The embodiment that Fig. 3 shows comprises: the centre position of the body of rod 11 is joint portion 13, both sides form action bars 14 separately,, an extension bar 12 passes this joint portion 13, the ratchet group 15 of one client link just can be assembled in the joint portion 13, finish the T type ratchet spanner 10 of another simple-type.Be with the maximum difference of the foregoing description: this extension bar 12 is held the non-circular sleeve port one 8 that caved inward in addition, in order to the sleeve 20 of socket different size.

Fig. 4 shows the T type ratchet spanner 10 of another kind of laborsaving formula, comprise: the centre position of the body of rod 11 is joint portion 13, both sides form 14, one extension bars 12 of action bars separately and pass this joint portion 13, the ratchet group 15 of a client link just can be assembled in the joint portion 13 form.Be with the difference of above-mentioned two embodiment maximums: be connected with the pole 19 of scalability on the action bars 14 of these spanner 10 both sides, extend the spacing that both hands grip in order to draw back, and then make things convenient for us to manipulate.

The utility model compared with prior art has following effect:

1) control stable: for existing ratchet spanner, the bilateral application of force is from than the monolateral mode of controlling more For steadily and easily locating.

2) laborsaving: as for front case, to promote for reaching torsion, desperately lock Compress Spring to improve sour jujube The intensity of wheel engagement is instead come laborsavingly not as the utility model extends force arm length.

3) assembling flow path is simple: be to promote the front case of torsion, must numerous part assembly and finish, and organize The dress flow process is quite loaded down with trivial details; The required part of the utility model is few, and assembling flow path is relatively simple and easy.

4) particular surroundings is constructed easily: the apparatus vehicle has the darker irrigation canals and ditches of the degree of depth, existing ratchet spanner is desired in this particular surroundings operation, certainly will connect the long adapter sleeve of pegging graft again could operate, the sleeve that the sleeve position has been had the gap originally, so length will be unfavorable for the transmission of strength, even disengaging is dropped easily; Review the utility model and then can construct easily, and reduce to take over so indirect element, causing does not have this drawback during the strength transmission and produces.

Claims

1, a kind of T type ratchet spanner, it is characterized in that, system comprises: the centre position of the body of rod is the joint portion, both sides form action bars separately, an extension bar passes this joint portion, the ratchet group of one client link just can be assembled in the joint portion, and this extension bar other end can form non-circular driving head or sleeve port, in order to the grafting sleeve.

2, T type ratchet spanner according to claim 1 is characterized in that, is connected with the pole of scalability on this action bars.
