Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a bolt, as shown in fig. 1, including being columniform nut 1, 1 lower extreme integrated into one piece of nut has screw rod 2, and nut 1 is carried on the back both sides wall mutually and has all been seted up along circumference and has been rotated groove 11, and nut 1 articulates in the one end that rotates groove 11 and is curved rotor arm 3, and rotor arm 3's expansion end passes through mounting 4 to be fixed in rotating groove 11. When the bolt needs to be rotated, the rotating arm 3 on the side wall of the nut 1 is rotated out of the rotating groove 11, and the rotating arm 3 is pinched by hands, so that the bolt is directly rotated, and time and labor are saved.

As shown in fig. 2, the fixing element 4 includes two fixing arms 41 that are respectively connected with the two movable ends of the rotating arm 3, wherein the two movable ends are opposite to each other and are cylindrical, fixing grooves 12 for the fixing arms 41 to be clamped in are respectively formed in two opposite inner walls of the rotating groove 11 of the nut 1, two opposite side walls of the fixing arm 41 are fixedly connected with fixing blocks 42 that are hemispherical, and the fixing blocks 42 are made of hard rubber and have certain deformation capability. When the rotating arm 3 is rotated back to the rotating groove 11, the fixing arm 41 is clamped into the fixing groove 12, so that the fixing fixture block 42 on the fixing arm 41 is deformed and clamped into the fixing groove 12 and tightly props against the inner wall of the fixing groove 12, the fixing fixture block 42 and the inner wall of the fixing groove 12 generate friction force, the fixing arm 41 is prevented from being separated from the fixing groove 12 under the action of no external force, and the rotating arm 3 is fixed in the rotating groove 11. Meanwhile, the contact area between the fixed arm 41 and the fingers can be increased, when people pinch the movable end of the rotating arm 3 by the fingers, the fixed arm 41 is pinched at the same time, the connection stability between the fingers and the rotating arm 3 is improved, and the fingers and the rotating arm 3 are prevented from slipping off

As shown in fig. 2, the side of the rotating arm 3 away from the rotating groove 11 is integrally formed with a reinforcing strip 7 along the length direction thereof. The reinforcing bar 7 can increase the cross-sectional area of the rotor arm 3, thereby increasing the bending resistance of the rotor arm 3 and preventing the rotor arm 3 from being bent accidentally.

As shown in fig. 2, the inner walls of the long sides of the rotating groove 11 are fixedly connected with the sealing gaskets 5 made of silica gel along the length direction thereof. When the rotating arm 3 is rotated into the rotating groove 11, the sealing gasket 5 is extruded to deform, so that a gap between the rotating arm 3 and the side wall of the rotating groove 11 is filled, water vapor and dust in the air are prevented from entering the rotating groove 11, and the rotating arm 3 is prevented from being corroded; at the same time, the packing 5 can be closely attached to the side wall of the rotating arm 3, thereby preventing the rotating arm 3 from being separated from the rotating groove 11.

As shown in fig. 2, the movable end of the rotating arm 3 is hinged with an arc-shaped extension rod 6, and a placing groove 31 for the extension rod 6 to be clamped in is formed along the length of the movable end of the rotating arm 3 and one side of the bottom wall of the rotating groove 11, which is tightly attached to each other. The extension rod 6 can increase the length of the rotating arm 3, which is equivalent to increasing the rotating arm, so that people can rotate the bolt more laborsavingly. When the rotating arm 3 is stored, the extension rod 6 is only required to be turned into the placing groove 31, and then the rotating arm 3 is turned into the rotating groove 11. The length of standing groove 31 is greater than the length of extension rod 6 for people can rotate the live end of extension rod 6 out of standing groove 31 with the finger through the space between extension rod 6 and standing groove 31, labour saving and time saving.

The use process comprises the following steps:

the movable end of the rotary arm 3 is rotated out of the rotary groove 11 by fingers, the extension bar 6 in the placement groove 31 is rotated out, and then the extension bar 6 is held by hand and rotated, thereby loosening the bolt without an additional tool.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
