Sleeve assembly and electric tool

An electric tool, comprising:

• a housing;
• a motor arranged in the housing;
• a transmission mechanism connected to the motor;
• an output shaft driven by the transmission mechanism, and partially exposed from a front end of the housing;
• and
• a sleeve assembly configured to screw a nut to a bolt located on a to-be-fixed component, the sleeve assembly comprising:
• a sleeve defining a receiving cavity recessed backward from a first end face of the sleeve, and the nut being received in the receiving cavity;
• a pull rod assembly, arranged in the receiving cavity, and comprising:
• a pull rod extending along a central axis of the sleeve;
• a pulling component arranged at one end of the pull rod;
• and
• a bearing arranged at another end of the pull rod opposite to the pulling component;
• wherein the pull rod is connected to an inner wall of the sleeve through the bearing, and the pull rod is rotatable relative to the sleeve;
• in response to the sleeve assembly screwing the nut, the pulling component is configured to drive the bolt to be attached to a surface of the to-be-fixed component;
• wherein the sleeve assembly is fixedly connected to a first end of the output shaft away from the motor;
• wherein the pulling component is configured to attract the nut to move to a periphery of the pulling component in a case where the nut is received in the receiving cavity.

An electric tool configured to screw a nut to a bolt located on a to-be-fixed component, the electric tool comprising:

• a housing;
• an output shaft partially exposed from a first end of the housing;
• and
• a sleeve assembly comprising:
• a sleeve extending along an axial direction of the output shaft, wherein the output shaft is inserted into the sleeve;
• a pull rod assembly received in the sleeve and comprising:
• a pull rod extending along the axis direction of the output shaft and rotatably connected to the sleeve;
• and
• a magnetic component arranged at one end of the pull rod away from the output shaft;
• wherein the magnetic component is configured to attract the nut to move to a periphery of the magnetic component in a case where the nut is received in the sleeve;
• wherein in response to the sleeve assembly screwing the nut, the magnetic component adsorbs the bolt, and the sleeve assembly applies a force to the bolt, such that the bolt is attached to a surface of the to-be-fixed component.
