Abstract

The utility model relates to a variable pitch sleeve barrel, provided with three claws which are uniformly distributed on the end face of a sleeve barrel body and radially move along a positioning device on the end face. A rotating manual body can cause the claws to clamp a screw cap or withdraw. A pair of sleeve barrel can replace a plurality of pairs of sleeve barrel by adopting the utility model, with convenience and economy.

Description

But displacement sleeve

The utility model relates to the instrument that a kind of mechanical work is used, and particularly turns on or tighten the nut of different-diameter, the instrument that screw is used.

In known technology, above-mentioned operation all will be used instrument, especially sleeves such as monkey wrench or box spanner, must prepare to overpay, and in order to the needs of different size, the very trouble that seems is scattered and is lost also possiblely, therefore improves being necessary.

But the purpose of this utility model provides a kind of displacement sleeve that can overcome the known technology shortcoming.

For achieving the above object, scheme of the present utility model is: but the two or more at least claws of a kind of displacement sleeve setting are distributed on the end face of sleeve body, and move radially along the setting element on the end face, an end that embeds sleeve body on the claw is carved with flat thread, cooperate with another manual body that is carved with screw thread, described manual body cooperates with sleeve body, and there is the polygonal hole of accepting to apply moment the back of sleeve body.

Adopt such scheme, can realize the purpose of this utility model.

Below by diagram and embodiment scheme is described in more detail.

But Fig. 1 is the front view of displacement sleeve;

But Fig. 2 is the side view of displacement sleeve;

But Fig. 3 is the sleeve body front view of displacement sleeve;

But Fig. 4 is the sleeve body side view of displacement sleeve;

But Fig. 5 is the manual body front view of displacement sleeve;

But Fig. 6 is the claw front view of displacement sleeve;

But the claw vertical view of Fig. 7 displacement sleeve;

Be the installation diagram of a specific embodiment as depicted in figs. 1 and 2; But the displacement sleeve of present embodiment has three claws (1); be distributed on the end face of sleeve body (2); claw (1) is installed on the sleeve body (2); element for claw (1) location on the end face of sleeve body (2) is three grooves entad on the end face; going up corresponding projection with claw (1) cooperates; make claw (1) draw close or leave to the center; the rear end bulge loop of claw (1) is carved with flat thread (3); described flat thread (3) matches with the flat thread of manual body (4), and the flat thread on claw (1) and the manual body (4) is that right-hand thread or left-hand thread all can.

The structure of sleeve body as shown in Figures 3 and 4, described sleeve body is the cylindrical body of a T shape, the center is a ladder hole (5) and (6), (6) hole can be polygonal hole, but present embodiment is a square opening, be carved with three grooves (7) entad on the big end upper surface of sleeve body (2), on the other end, dug annular opening (8), opening (8) communicates with groove (7), and the bulge loop that manually is carved with flat thread on the body (4) is by annular opening on the sleeve body and the engagement of claw flat thread.The small end of sleeve body (2) is one section garden tube (9), described garden tube (9) matches with manual body (4), manually be carved with flat thread on the bulge loop (10) on the body (4), an axial displacement of an annular end face (11) the limit manual body of sleeve body (2) limits another axial displacement by the snap ring (12) on the sleeve body (2) again.

But above-mentioned displacement sleeve in use, the manual body of turn (4) then flat thread drive claw moves, can clamp the hexagonal (hexagon)nut in the 6-17mm scope, insert in the square hole (6) with a rod then with square elbow, but application of force square turn sleeve then, replace one group of sleeve with a sleeve, this will make things convenient for, and is much economical.

In sum, the utility model is effective.

Claims (7)

1. But 1, a kind of displacement sleeve, it is characterized in that: two or more at least claws are set are distributed on the end face of sleeve body, and move radially along the setting element on the end face, an end that embeds sleeve body on the claw is carved with flat thread, cooperate with another manual body that is carved with flat thread, manually body is installed on the sleeve body, and there is the polygonal hole of accepting to apply moment the back of sleeve body.
2. But 2, bending moment sleeve according to claim 1 is characterized in that: three claws are distributed on the end face of sleeve body (2).
3. But 3, bending moment sleeve according to claim 1 is characterized in that: it is three grooves entad on the end face that sleeve body (2) goes up element for claw (1) location.
4. But 4, bending moment sleeve according to claim 1 is characterized in that: the bulge loop that manually is carved with flat thread on the body (4) meshes with the claw flat thread by an annular opening on the sleeve body.
5. But 5, displacement sleeve according to claim 4 is characterized in that: an axial displacement of an annular end face limit manual body of sleeve body (2) is arranged on another axial displacement of the snap ring limit manual body (4) on the sleeve body (2).
6. But 6, displacement sleeve according to claim 1 is characterized in that: the hole that the back of sleeve body (2) has acceptance to apply moment is a square hole.
7. But 7, displacement sleeve according to claim 1 is characterized in that: the flat thread on claw (1) and the manual body (4) is that right-hand thread or left-hand thread all can.
