second connection parts

2 and 3 are oppositely moved, the space between the hoops 4 is easier to be enlarged, the hoops 4 can more conveniently rotate on the main body 1, and similarly, when the magnetic strip and the magnetic area 7 are mutually attracted magnetic poles, the first connecting part 2 and the second connecting part 3 are close to each other, and after the bolt is rotated, the bolt is easy to rotate, and the hoop 4 is more tightly fixed on the main body 1 under the action of magnetic force.

The inside of the hoop 4 is provided with a cover body 16, the main body 1 further comprises a gear box 18, a transmission shaft penetrates through the gear box 18, an abrasive disc 20 is mounted on the transmission shaft, the abrasive disc 20 rotates along with the rotation of the transmission shaft, as shown in fig. 1, the cover body 16 is arranged outside the abrasive disc 20, and the hoop 4 is connected to the gear box 18, that is, the hoop 4 can be fixed on the gear box 18 or can move on the gear so as to change the angle of the protective cover, and the technical personnel in the field should know how the abrasive disc 20 rotates, how the gear box 18 realizes the rotation of the transmission shaft, and how the hoop 4 is connected with the gear box 18.

The main body 1 comprises a hand-held portion 21, the hand-held portion 21 is provided with a switch for starting the grinding plate 20, the main body 1 is generally controlled by a rotating motor to rotate a transmission shaft of the gear box 18, the switch is used for controlling the rotating motor, and the rotating motor supplies power to the rotating motor through a lithium battery 22 arranged at the tail end of the main body 1.

The magnetic force direction between the magnetic strips can be controlled by manually adjusting the magnetic poles at one side of the magnetic strip relative to the magnetic area 7, and the manual adjustment mode is still inconvenient, so that the magnetic strip is improved.

All set up the through-hole on first connecting portion 2 and the second connecting portion 3 through-hole department on the second connecting portion 3 sets up and rotates cover 8, will it connects to rotate cover 8 and rotate in the through-hole of second connecting portion 3, will screw rod 5 passes first connecting portion 2 and rotates cover 8, simultaneously screw rod 5 directly has the friction with rotating cover 8, and is further screw rod 5 is in when rotating in the rotating cover 8, because the existence of frictional force rotate cover 8 along with it and rotate.

A screw head is arranged at one end of the screw 5, the screw head is positioned at the side of the second connecting part 3, namely, the side of the screw 5 without the head sequentially enters the rotating sleeve 8, the first connecting part 2 and the nut 6, a first magnetic strip 9 and a second magnetic strip 10 are arranged on the rotating sleeve 8, referring to fig. 4, the first magnetic strip 9 and the second magnetic strip 10 are oppositely arranged, specifically, the first magnetic strip 9 faces the S pole of the first linking part, the second magnetic strip 10 faces the N pole of the first connecting part 2, the state in fig. 4 is that the second magnetic strip 10 faces one side of the magnetic area 7, namely the S pole is arranged on the magnetic area 7, the first connecting part 2 and the second connecting part 3 are in an attraction state, if the screw 5 is required to be rotated to fall off, the rotating sleeve 8 needs to be rotated by 180 degrees, and the S pole of the first magnetic strip 9 is opposite to the magnetic area 7, the first connection part 2 and the second connection part 3 are in a pair of repulsion.

First magnetic stripe 9 and second magnetic stripe 10 are connected with rotation cover 8 through connecting rod 11 respectively, first magnetic stripe 9 and second magnetic stripe 10 bottom are equipped with mount pad 14, mount pad 14 passes through screw 15 to be fixed on connecting rod 11, the angle between first magnetic stripe 9 and the second magnetic stripe 10 is 180 degrees set up gliding stopper 12 on the second connecting portion 3, stopper 12 slides in slide 13, just stopper 12 can gliding distance be the position that connecting rod 11 rotated 180 degrees back and is located, see figure 4, work as after anticlockwise reverse rotation 180 degrees of first magnetic stripe 9, second magnetic stripe 10 drives the slider rebound back to second magnetic stripe 10 rotates 180 degrees back, the slider is spacing, and the clockwise forward rotation 180 degrees back again of the same reason, stopper 12 is spacing after rotating 180 degrees equally.

The screw rod 5 is further convenient to rotate, and the rotating piece 17 is arranged at the head of the screw rod, namely the rotating piece 17 is held by a hand, so that the screw rod 5 is convenient to rotate.

The working principle is as follows: when the anchor ear 4 needs to be loosened to adjust the angle, the rotating part 17 is held, the rotating sleeve 8 synchronously rotates under the action of friction force after the screw rod 5 is rotated anticlockwise and reversely, when the rotating sleeve 8 and the first magnetic strip 9 rotate 180 degrees and are limited by the limiting block 12, and the first magnetic strip 9 and the magnetic area 7 are opposite to each other in repulsive magnetic force, the screw rod 5 continuously overcomes the rotating sleeve 8 and then rotates, so that the screw rod 5 moves towards the direction of disengaging the nut 6, and when the screw rod 5 disengages from the nut 6, the first connecting part 2 and the second connecting part move in a repulsive manner, so that the distance of the anchor ear 4 is increased, and the anchor ear 4 can be conveniently positioned in the gear box 18 to rotate; in a similar way, the screw rod 5 passes through the rotating sleeve 8 and the nut 6, then the screw rod 5 is rotated clockwise and forwardly, the rotating sleeve 8 rotates 180 degrees and then is not moved, namely, the magnetic force is attracted between the second magnetic stripe 10 and the magnetic area 7, namely, the second connecting part 3 returns to the first connecting part 2 and is close to the first connecting part in advance, at the moment, the rotating part 17 and the screw rod 5 rotate and then enter the nut 6 more easily, and the operation is rapid and simple.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
