The first arm 131 is pivotally connected to the first swing lever 141 by the engagement of the third pin 145 with the first stopper 147, and the second arm 132 is pivotally connected to the second swing lever 142 by the engagement of the fourth pin 146 with the second stopper 148.
Referring to fig. 11 to 12, the first swing lever 141 is provided with a first rectangular recess 161 for partially receiving the head of the screw 0 and a first half hole 163 for partially receiving the shaft of the screw 0, the first half hole 163 is communicated with the first rectangular recess 161, the end of the first swing lever 141 is provided with a first slope, and when the head of the screw 0 abuts against the first slope, the first swing lever 141 is rotated and separated from the second swing lever 142. The second swing lever 142 is provided with a second rectangular groove 162 for partially receiving the head of the screw 0 and a second half-side hole 164 for partially receiving the rod of the screw 0, the second half-side hole 164 is communicated with the second rectangular groove 162, the end of the second swing lever 142 is provided with a second inclined surface, and when the head of the screw 0 abuts against the second inclined surface, the second swing lever 142 is rotated and separated from the first swing lever 141. The first rectangular groove 161 and the second rectangular groove 162 form a groove for receiving the head of the screw 0, and the first half hole 163 and the second half hole 164 form a hole for receiving the shaft of the screw 0. When the head of the screw 0 abuts against the first inclined surface and the second inclined surface, the first swing lever 141 and the second swing lever 142 rotate and separate from each other, when the head of the screw 0 enters a space formed by the first rectangular groove 161 and the second rectangular groove 162, the first swing lever 141 and the second swing lever 142 rotate and abut against each other under the elastic force of the tension spring 15, the head of the screw 0 is limited in the rectangular groove formed by the first rectangular groove 161 and the second rectangular groove 162, the rectangular groove limits the rotation and the axial movement of the head of the screw 0, and when the screw 0 rotates by a small amplitude under the action of the cleaning brush 22, the screw 0 drives the clamping assembly 42 to rotate by a small amplitude. The first half hole 163 of the first swing lever 141 and the second half hole 164 of the second swing lever 142 surround the shaft portion of the screw 0 to increase stability during the process in which the screw 0 is clamped.
Referring to fig. 13, the power spring 12 includes a first end portion 121 provided to the outer race and a second end portion 122 provided to the inner race, the first end portion 121 having a hook structure, and the second end portion 122 being provided with a through hole.
Referring to fig. 15, the hook structure of the first end portion 121 of the clockwork spring 12 is engaged with the first lever 102 of the mounting case 10, and the through hole of the second end portion 122 of the clockwork spring 12 is engaged with the second shaft portion 134 of the rotating disc 13. The first shaft portion 133 of the rotating disc 13 is rotatably fitted in the blind hole 105 of the first seat 101 of the mounting case 10, the second shaft portion 134 of the rotating disc 13 is slidably fitted in the first slide way 103 and the second slide way 104 of the first seat 101, the first end portion 121 of the clockwork spring 12 is hooked on the first rod 102, the second shaft portion 134 of the rotating disc 13 is inserted into the through hole of the second end portion 122 of the clockwork spring 12, the rotating disc 13 is rotated to rotate and preload the clockwork spring 12, and finally the second shaft portion 134 of the rotating disc 13 is inserted into the first slide way 103, and under the elastic force of the clockwork spring 12, the second shaft portion 134 is pulled into the second slide way 104 and stays in the second slide way 104. The axial restraint by the second slide 104 effects a rotational connection of the mounting box 10 to the rotary disk 13 and restrains the spring 12 between the mounting box 10 and the rotary disk 13. When the screw 0 is rotated by a small amplitude under the action of the cleaning brush 22, the screw 0 is rotated back to the original position under the elastic force of the spring 12, and has certain toughness in the rotation process of the screw 0, thereby increasing the cleaning area of the outer surface of the screw 0.
