Description

Electric tool protection casing adjusting device and electric tool

Technical Field

The present application relates to a power tool guard adjustment device and a power tool equipped with such a device.

Background

The existing electric tool protective cover is characterized in that a hoop encircling the tool front cover is fixed on the cover body, two lugs are respectively formed at two ends of the length of the hoop, screw holes are formed in the lugs, and the hoop is fastened on the front cover through screws which are locked and connected between the two lugs, so that the cover body and the front cover are fixed.

When a user needs to adjust the installation angle of the cover body on the front cover, the screw is unscrewed by a screwdriver, then the cover body and the anchor ear are rotated to the required angle position together, and the screw is screwed by the screwdriver, so that the cover body is fixed at the new angle position. The adjustment of the mounting angle of the cover body is realized by a screwdriver, which is very troublesome.

The purpose of the application is as follows: to above-mentioned problem, this application provides a novel structure's electric tool protection casing adjusting device and disposes electric tool of this kind of device, and it need not to realize the regulation of protection casing cover body installation angle on the protecgulum with the help of the screwdriver.

The technical scheme of the application is as follows:

an electric tool shield adjustment device comprising:

cover body

The hoop is fixed with the cover body and surrounds the front cover;

one end of the length of the anchor ear is fixedly connected with a male bayonet lock, the other end of the length of the anchor ear is connected with a spanner, and a female bayonet lock matched with the male bayonet lock is fixed on the spanner; the female bayonet can be selectively clamped/separated from the male bayonet by the action of the wrench.

The power tool protection cover adjusting device further comprises the following preferable schemes on the basis of the technical scheme:

the male bayonet lock is with the axle position screw of staple bolt screw thread locking.

The female bayonet lock is with spanner screw thread locking's axle position screw.

The spanner is fixedly connected with the anchor ear through a screw.

The screw is in threaded connection with a threaded hole formed in the wrench.

The screw penetrates through a through hole formed in the hoop and can axially move relative to the through hole.

An electric tool comprises the electric tool protective cover adjusting device with the structure.

The application has the following beneficial effects: the electric tool protective cover adjusting device is simple in structure and convenient to operate, and the installation angle of the protective cover body on the front cover can be adjusted without a screwdriver.

Drawings

The present application is further described with reference to the accompanying drawings and specific embodiments:

FIG. 1 is a schematic view of a protective cover adjusting device of an electric tool according to an embodiment of the present application;

fig. 2 is an exploded view of a power tool guard adjustment device in an embodiment of the present application.

Wherein: 1-cover body, 2-anchor ear, 3-male bayonet lock, 4-spanner, 5-female bayonet lock, 6-screw, 7-protecgulum.

Detailed Description

Fig. 1 and 2 show a specific embodiment of a protective cover adjusting device for a power tool of the present application, which, like a conventional protective cover adjusting device for a power tool, also includes a cover body 1 and a hoop 2 fixed to the cover body. The anchor ear is the annular structure of taking the opening, and it is embraced on the protecgulum 7 of electric tool. In this embodiment, the anchor ear 2 is integrally formed on the cover body 1, and both are made of metal materials. Of course, it is also possible to provide the anchor ear 2 and the cover 1 as two separate pieces, and then to weld the two pieces together.

The key improvement of this embodiment is: one end of the length of the anchor ear 2 is fixedly connected with a male bayonet lock 3, the other end of the length of the anchor ear 2 is connected with a spanner 4 through a screw 6, and a female bayonet lock 5 matched with the male bayonet lock 3 is fixed on the spanner 4. And the female bayonet 5 can be selectively engaged with/disengaged from the male bayonet 4 by the action of the wrench 4.

In this embodiment, the male bayonet lock 3 and the female bayonet lock 5 are shaft screws, which are respectively locked and fixed with the anchor ear 2 and the wrench 4 by threads.

Referring to fig. 1, in a normal state, the female bayonet lock 5 is clamped at the lower part of the male bayonet lock 3, so that two ends of the anchor ear 2 are tightly pulled, and the anchor ear 2 is tightly held on the front cover 7, thereby stabilizing the cover body 1 at a corresponding angle position. When the angle of the cover body 1 on the front cover 7 needs to be adjusted, the spanner 4 is pulled, so that the female bayonet lock 5 on the spanner moves along with the spanner to climb over the male bayonet lock 3 to move to other positions, and the female bayonet lock 5 and the male bayonet lock 3 are separated from each other and are not clamped. The two ends of the anchor ear 2 are not tensioned any more. After the cover body 1 is rotated to a required angle position, the wrench 4 is pulled in the opposite direction, so that the female bayonet lock 5 on the wrench 4 climbs to the male bayonet lock 3 and is clamped again with the male bayonet lock 3, and the cover body 1 is stabilized at the new angle position.

The screw 6 is used for connecting the spanner 4 and the anchor ear 2: in fig. 2, a vertical threaded hole is formed in the upper part of the wrench 4, and a screw 6 is in threaded connection with the threaded hole on the wrench 4; the upper end of the opening of the anchor ear 2 is provided with a smooth wall through hole with larger aperture, and the screw 6 is arranged in the through hole in a penetrating way and can axially move relative to the through hole. By means of the design, the spanner 4 can move up and down very conveniently relative to the hoop 2, the angular position of the cover body 1 can be adjusted conveniently, and the connection depth of the through hole adjusting screw 6 and the spanner 4 can be used for adjusting the environment-friendly tightness of the hoop 2 to the front cover 7.

Of course, the foregoing embodiments are merely illustrative of the technical concept and features of the present application, and are intended to enable people to understand the content of the present application and implement the same, not to limit the protection scope of the present application. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present application should be covered in the protection scope of the present application.
