[0028] The utility model is further illustrated by combining with the drawings and specific embodiment, as Figures 1-5 The sleeve assembly with anti-skid design according to the embodiment of the utility model, it includes sleeve assembly body 1, sleeve upper end 11, work space 111, annular arc angle 112, sleeve angle accommodating space 113, spring hole 114, sleeve middle part 12, sleeve lower end 13, clamping moving part 2, anti-skid layer 21, guide arc 22, reinforcing arc 23, spring 3, friction pad 4.

[0029] When using the sleeve fastening nut, bolt and other operated components, the nut, bolt and other operated components are pressed into the work space 111 in the sleeve upper end 11, and the operating component is guided into the work space 111 through the fixed guide of annular arc angle 112 and guide arc 22, and when gradually entering the work space 111, the corner part of the operated component is accommodated in the sleeve angle accommodating space 113, preventing the sharp part from directly contacting the sleeve, and at the same time, the guide arc 22 is pressed to push the clamping moving part 2 to move to the direction of spring 3, so as to leave more space to accommodate the operated component. When the operated component completely enters the work space 111, the anti-skid layer 21 on the surface of the clamping moving part 2 is completely contacted, which greatly increases the friction between the operated component and the sleeve. When the worker rotates with force, the operated component is pressed on the friction pad 4 and closely attached to the friction pad 4, further increasing the friction, preventing the sleeve from slipping, effectively preventing the relative sliding between the sleeve and the operated component, and ensuring the stable transmission of torque.

[0030] The sleeve middle part 12 is connected with the sleeve upper end 11 and the sleeve lower end 13, and plays a supporting and torque transmission role, ensuring the structural strength of the whole sleeve assembly.

[0031] The sleeve lower end 13 is clamped as a position, connected with the output end of the motor and the electric drill, driving the rotation of the sleeve middle part 12 and the sleeve upper end 11.

[0032] Working principle: positioning and entering: when using, the nut, bolt and other operating components are pressed into the working space 111 of the upper end 11 of the sleeve, the annular arc angle 112 and the guide arc 22 play a fixed guiding role, the corner of the operating component enters the corner containing space 113 of the sleeve, avoiding direct contact of the sharp part with the sleeve, and at the same time, the guide arc 22 pushes the clamping moving part 2 to move to the spring 3 direction, so as to provide more containing space for the operating component.

[0033] Friction force increases: after the operating component completely enters the working space 111, the anti-skid layer 21 on the surface of the clamping moving part 2 is contacted, the friction force between the sleeve is increased. When the worker rotates the sleeve, the operating component is pressed on the friction pad 4, and the two are closely attached, so as to further enhance the friction force and prevent slipping.

[0034] Torque transmission: the middle part 12 of the sleeve connects the upper end 11 and the lower end 13 of the sleeve, and plays a supporting and torque transmission role. The lower end 13 of the sleeve is connected with the motor and the output end of the electric drill, drives the whole sleeve to rotate, stably transmits the torque to the operating component, and completes the fastening work.
