Description
Technical Field
The utility model relates to a separation and reunion structure for electric tool.
Background
The clutch structure on the existing market is relatively complex, and the conventional electric tool is not provided with the clutch structure, so that when the electric tool is in a stuck state, the reaction force cannot be eliminated through the clutch structure, and the existing clutch structure is too complex and is not high in adaptability with the electric tool.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a separation and reunion structure for electric tool in order to solve above-mentioned problem, simple structure through two settings of getting rid of piece, extension spring, support and cylinder type shell, has formed the separation and reunion structure, has excellent separation and reunion effect.
The purpose of the utility model is realized like this:
the utility model discloses a separation and reunion structure for electric tool, include:
the bracket is connected with a driving mechanism for driving the bracket to rotate;
one end of each throwing block is hinged with the support, and the outer edge of each throwing block is an arc surface;
one end of each tension spring is connected with one end of one throwing block hinged with the bracket, and the other end of each tension spring is connected with the other end of the other throwing block;
each friction plate is arranged on the outer edge of one throwing block in a one-to-one correspondence manner; and
and the radian of the side wall of the cylindrical shell is matched with that of the friction plate.
The above clutch structure for the electric tool, wherein the radian of the friction plate is matched with the radian of the outer edge of the throwing block.
In the clutch structure for the electric tool, a gap is formed between the inner wall of the cylindrical shell and the friction plate.
The utility model has the advantages of it is following:
simple structure through two settings of getting rid of piece, extension spring, support and cylinder type shell, has formed the separation and reunion structure, and two get rid of the piece and receive two extension spring effects when throwing away, throw away in coordination, when two are thrown away the piece and do not receive centrifugal force, two are thrown away the piece and playback under the effect of two extension springs, have promoted the separation and reunion effect.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, a clutch structure for an electric tool according to the present invention is shown, including:
a bracket 1, the bracket 1 is connected with a driving mechanism (not shown) for driving the bracket 1 to rotate;
one end 21 of each throwing block 2 is hinged with the support 1, and the outer edge of each throwing block 2 is an arc surface;
one end of each tension spring 3 is connected with one end 21 of one throwing block 2 hinged with the bracket 1, and the other end of each tension spring 3 is connected with the other end 22 of the other throwing block 2;
the two friction plates 4 are arranged on the outer edge of one throwing block 2 in a one-to-one correspondence mode; and
and the cylindrical shell 5 covers the friction plate 4 and the swinging block 2, and the radian of the side wall of the cylindrical shell 5 is matched with that of the friction plate 4.
The radian of the friction plate 4 is matched with the radian of the outer edge of the throwing block 2.
A gap is formed between the inner wall of the cylindrical shell 5 and the friction plate 4.
The utility model discloses an use, during the use, it is rotatory through actuating mechanism (in the figure) drive support 1, thereby it is rotatory to drive and get rid of piece 2, because it is articulated with support 1 to get rid of piece 2, along with getting rid of piece 2 constantly rotatory, under the effect of centrifugal force, get rid of piece 2 not get rid of support 1 articulated one end and get rid of support 1, thereby it is rotatory with cylinder type shell 5 to get rid of the inner wall contact of piece 2 on this moment and cylinder type shell 5 drive cylinder type shell 5, the top and a drilling tool (in the figure) of cylinder type shell 5 are connected, thereby it rotates to drive drilling tool (in the figure), when actuating mechanism (in the figure) stop function, support 1 with get rid of piece 2 stall, get rid of piece 2 playback under the tensile force effect of extension spring 3, friction disc 4 and cylinder type shell 5 separation.
The utility model discloses a separation and reunion structure for electric tool, simple structure gets rid of piece 2, extension spring 3, support 1 and cylinder type shell 5's setting through two, has formed the separation and reunion structure, and two get rid of piece 2 and receive two extension springs 3 effects when throwing away, throw away in coordination, when two are got rid of piece 2 and do not receive centrifugal force, two get rid of piece 2 playback under the effect of two extension springs 3, have promoted the separation and reunion effect.
The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the relevant art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and should be defined by the claims.
