Abstract

The utility model provides a socket spanner for installing expansion bolts conveniently, relating to an installation tool for installing expansion bolts in engineering; the socket spanner comprises afixed sleeve with an opening at one end, the bottom part of the other end of the fixed sleeve is provided with a through hole, a central loop bar penetrates through the through hole, the central loopbar is stretched in one end of the fixed sleeve and is fixedly connected with a nut sleeve with a hexagonal inner cavity, the central loop bar is stretched out of one end of the fixed sleeve and is fixedly connected with a rotational handle, and the rotational handle is vertical to the central loop bar. When the socket spanner is operated, the nut of the expansion bolt is arranged in the nut sleeve with a hexagonal inner cavity, which is arranged at the front end of the central loop bar, the main body of the expansion bolt is held tightly by the fixed sleeve, and the fixed sleeve is used for controlling the main body of the expansion bolt to swing left and right, so as to lead the main body of the expansion bolt to be sent to the position of an installation mouth of an opposite wall body,and then the other end of the central loop bar is knocked in, the main body of the expansion bolt is inserted in the wall body, the central loop bar is rotated by the rotational handle, so as to screwdown the nut of the expansion bolt at the front end and achieve the purpose of fixing sectional material.

Description

A kind of convenient box spanner that setscrew is installed

Technical field

The utility model relates in the engineering erecting tools that setscrew is installed, and is specially adapted to square tube section bar and body of wall the installing and using of setscrew fixedly the time.

Background technology

In the prior art, relate generally to setscrew and fixedly all use general tool during section bar, if the template material can also gather together when being fixed on body of wall, if when being fixed on square tubing on the body of wall with setscrew, will because of fixed interface not at section bar top layer (as Fig. 2), cause using general tool to operate, difficulty is installed.If use some unconventional methods to settle, setscrew is placed when installing will be through repeatedly adjusting, and tend to cause nut to come off, thread damage, bolt distortion, and operational troubles such as rotation nut difficulty, and time-consuming taking a lot of work influence installation quality.

The utility model content

The purpose of this utility model provides a kind of convenient box spanner that setscrew is installed, and can setscrew be installed quickly and accurately, makes that to fix various section bars on body of wall efficient and convenient, improves installation accuracy.

In order to achieve the above object, the utility model is achieved in that a kind of convenient box spanner that setscrew is installed, the fixed sleeving that comprises an end opening, the bottom of the fixed sleeving other end is provided with through hole, place the center loop bar in the through hole, the fixedly connected inner chamber of an end that the center loop bar stretches into fixed sleeving is hexagonal nut sleeve, and the center loop bar stretches out the fixedly connected rotary handle of an end of fixed sleeving, and rotary handle and center loop bar are perpendicular.

During the utility model operation, with the inner chamber of the nut centering loop bar front end of setscrew is in the hexagonal nut sleeve, the main body of setscrew is held tightly by fixed sleeving, the main body of utilizing fixed sleeving to control setscrew swings, thereby accurately be sent to over against body of wall the place, hole is installed, knock the other end of center loop bar then, the setscrew main body is inserted in the body of wall, with rotary handle pivot loop bar, the nut of the setscrew of front end is screwed, reach the fixedly purpose of section bar.

In order to increase the face of knocking, the end that the center loop bar stretches out rotary handle connects and knocks projection, knocks projection and the center loop bar is perpendicular, can conveniently knock like this.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is the reference figure of the utility model use occasion.

Wherein, 1. center loop bar, 2. fixed sleeving, 3. nut sleeve, 4. rotary handle 5. knocks projection, 6. through hole, 7 bodies of wall, 8. setscrew, 9. square tubing is 10. installed the hole.

The specific embodiment

As shown in Figure 1, 2, a kind of convenient box spanner that setscrew is installed, the fixed sleeving 2 that comprises an end opening, the bottom of fixed sleeving 2 other ends is provided with through hole 6, place center loop bar 1 in the through hole, the fixedly connected inner chamber of an end that center loop bar 1 stretches into fixed sleeving 2 is hexagonal nut sleeve 3, and center loop bar 1 stretches out the fixedly connected rotary handle 4 of an end of fixed sleeving 2, and rotary handle 4 is perpendicular with center loop bar 1.Center loop bar 1 stretches out the end connection of rotary handle 4 and knocks projection 5, and it is perpendicular with center loop bar 1 to knock projection 5.

During this device operation, the nut of setscrew 8 can be positioned in the nut sleeve 3 of center loop bar 1 front end, center loop bar 1 is pulled outwardly, make the openend of nut sleeve 3 away from fixed sleeving 2, thereby make the main body of setscrew 8 can enter into 2 li of fixed sleevings, by fixed sleeving 2 main body of setscrew 8 is delivered to fixing 10 places, installation hole of square tubing 9 inwalls and body of wall 7, knock with iron hammer and to knock projection 5 on the center loop bar 1, make the main body of setscrew 8 enter 7 li of bodies of wall, make the spiral on the setscrew 8 forward the position to rotary handle 4 pivot loop bars 1.

The utility model can be adjusted accordingly according to size, the length of setscrew.The inner chamber of center loop bar front end is that hexagonal nut sleeve can be made of the material of carry magnet, has the effect of holding more.

Claims

1, a kind of convenient box spanner that setscrew is installed, it is characterized in that: the fixed sleeving that comprises an end opening, the bottom of the fixed sleeving other end is provided with through hole, place the center loop bar in the through hole, the fixedly connected inner chamber of an end that the center loop bar stretches into fixed sleeving is hexagonal nut sleeve, the center loop bar stretches out the fixedly connected rotary handle of an end of fixed sleeving, and rotary handle and center loop bar are perpendicular.

2, the convenient box spanner that setscrew is installed according to claim 1 is characterized in that: the end that described center loop bar stretches out rotary handle connects and knocks projection, knocks projection and the center loop bar is perpendicular.
