Description

Box spanner

Technical field

The utility model belongs to the nut fastened tools, specifically a kind of box spanner that a slice pad and nut can be installed in simultaneously at least on the bolt.

Background technology

In the time of on nut being fastened on screw thread bolt down, an operating personnel normally hand pin bolt, make it motionless, the another hand with pad and nut sleeve on the bolt and with hand nut is being screwed on the bolt earlier, and then with the further fastening nut of spanner.Not only waste time and energy, operation inconvenience, and also operating efficiency is extremely low.Especially when being installed in pad, elastic washer and two nuts on the bolt, need two people to cooperate just and can finish toward contact.Moreover, pad, elastic washer and nut also drop through regular meeting in installation process.

Summary of the invention

The purpose of this utility model be for overcome above-mentioned deficiency provide a kind of simple in structure, easy to operate, can be simultaneously pad, elastic washer and two nuts be installed in box spanner on the bolt.

The utility model comprises sleeve and handle, it is characterized in that the spacer sleeve that said sleeve is provided with the ut socket of bolt hole by the bottom and is sleeved on ut socket upper end forms.

The bottom of said ut socket is the ut socket that magnetic material layer was made or be provided with to magnetic material.

Said magnetic material layer is provided with the through hole coaxial with said bolt hole.

The upper end of said ut socket and the lower end of said spacer sleeve are interference fit.

One end of said handle is provided with for the jack that is sleeved on the said ut socket.

Said jack and said ut socket are interference fit.

The utility model can be finished the installation of pad and nut simultaneously by continuous ut socket and spacer sleeve are set; Bottom adopting, make or be provided with the ut socket of magnetic material layer, can avoid pad, elastic washer and nut in installation process, to drop for magnetic material.Thereby have characteristics simple in structure, easy to operate, high efficiency.

Among the figure: 1---sleeve (11---bolt hole, 12---ut socket, 13---spacer sleeve), 2---handle (21---jack), 3---magnetic material layer (31---through hole).

The specific embodiment

Further specify the utility model below in conjunction with drawings and Examples.

Embodiment: sleeve 1 is provided with the ut socket 12 of bolt hole 11 and forms with the spacer sleeve 13 that is sleeved on ut socket 12 upper ends by the bottom, one end of handle 2 is provided with for the jack 21 that is sleeved on the ut socket 12, magnetic material layer 3 is positioned at the bottom outside of ut socket 12 and is provided with the through hole 31 coaxial with bolt hole 11, wherein, the lower end of the upper end of ut socket 12 and spacer sleeve 13 is an interference fit, and jack 21 is enclosed within the middle part of ut socket 12 and promptly becomes the utility model with ut socket 12 interference fit.

When the utility model was used for installing simultaneously a slice pad and a nut, the degree of depth of ut socket 12 was that the thickness of a nut adds 5mm again, and the degree of depth of spacer sleeve 13 upper ends is that the thickness of a pad adds 3mm again.When being used for installing simultaneously a slice pad, an elastic washer and two nuts, the degree of depth of ut socket 12 is that the thickness that the thickness of two nuts adds an elastic washer adds 5mm again, and the degree of depth of spacer sleeve 13 upper ends still is that the thickness of a pad adds 3mm again.

During use, be example so that a slice pad, an elastic washer and two nuts to be installed simultaneously, its operating procedure is: 1, two nuts and an elastic washer are put into ut socket 12 successively; 2, a slice pad is put into spacer sleeve 13 (at this moment, pad, elastic washer and nut be not all because of being held and can come off by magnetic material layer 3); 3, pad, elastic washer and the nut that will the be positioned at sleeve 1 back rotary handle 2 that aligns with bolt can be tightened nut and bolt, and the bolt stem of bolt is then passed from bolt hole 11 and through hole 31; 4, can remove the utility model after firmly overcoming the gravitation of magnetic material layer 3.
