Through adopting above-mentioned technical scheme, the glue ring that sets up the prismoid form changes dispersed pressure, further reduces the pressure of installation sleeve to the expand tube, makes the difficult production damage of expand tube.
As a further explanation of the present invention, it is preferable that the length of the mounting sleeve is greater than the length of the bolt extending out of the expansion tube.
Through adopting above-mentioned technical scheme, avoid pounding the bolt when the hammering, guarantee that the bolt does not receive the damage.
As a further explanation of the present invention, preferably, one end of the mounting sleeve close to the rubber ring is fixedly connected with a backing ring, and the outer diameter of the backing ring is equal to the outer diameter of the rubber ring.
Through adopting above-mentioned technical scheme, set up the area of contact of backing ring increase installation sleeve and gluey ring, make gluey ring atress even, avoid gluing ring local stress too big and damaged.
As a further explanation of the present invention, preferably, one side of the mounting sleeve is fixedly connected with a handle, and the length direction of the handle is perpendicular to the axis direction of the mounting sleeve.
Through adopting above-mentioned technical scheme, set up the handle and avoid pounding the staff when hammering installation sleeve, degree of safety when improving the installation.
As a further explanation of the present invention, preferably, one end of the handle away from the mounting sleeve is provided with a wire loop.
Through adopting above-mentioned technical scheme, set up the wire loop and can wear the installation sleeve together, be convenient for deposit.
The utility model discloses following beneficial effect has:
1. the utility model increases the contact area between the hammer and the expansion pipe by arranging the mounting sleeve, so that the expansion pipe is easier to be inserted into the hole, and the rubber ring is arranged to reduce the abrasion between the mounting sleeve and the expansion pipe and avoid the generation of depression;
2. the handle is arranged to prevent hands from being hit when the sleeve is hammered and installed;
3. the expansion pipe is easier to expand, and the installation difficulty is reduced.
