The magnetic device includes a first end and a second end. The first end is magnetic. The detachable positioning device includes a connecting end slidably disposed on the second end of the magnetic device, such that the magnetic device axially slides against the detachable positioning device. The detachable positioning device further includes a resilient quick detach device disposed on one end of the detachable positioning device away from the connecting end, whereby the detachable positioning device is removably disposed in a sleeve. Therefore, when the sleeve is damaged or broken, the adjustable magnetic seat is efficiently removed from the sleeve and re-installed in a new sleeve replacement. ## Claims ### Claim 1 A quick detachable and adjustable magnetic seat for a sleeve comprises: a magnetic device including: a first end; a second end; and a first axle member; wherein the first end is magnetic and disposed on one end of the first axle member, the second end is disposed on another end of the first axle member; and a detachable positioning device including: a second axle member; a sliding seat; a connecting end attaching to one end of the second axle member; and a resilient quick detach device, disposed on another end of the second axle member away from the connecting end; wherein the sliding seat is slidably disposed on an outer periphery of the second axle member, the second axle member is slidably disposed on the second end, the connecting end is slidably disposed on the first axle member; and a spring disposed between the magnetic device and the detachable positioning device and resisting upon the sliding seat, wherein the magnetic device axially slides against the detachable positioning device and moves back to an original position after sliding against the detachable positioning device, and the detachable positioning device is removably disposed in the sleeve. ### Claim 2 (depends on 1) The quick detachable and adjustable magnetic seat of claim 1, wherein when the adjustable magnetic seat is being disposed in the sleeve, the adjustable magnetic seat is axially pushed along the sleeve toward one end of the sleeve, so as to be engaged therein; when the adjustable magnetic seat to be removed from the sleeve, the adjustable magnetic seat is axially pushed toward the other end of the sleeve, so as to be efficiently removed from the sleeve. ### Claim 3 (depends on 2) The quick detachable and adjustable magnetic seat of claim 2, wherein the resilient quick detach device is a resilient engage member, the detachable positioning device has a first outer diameter, the resilient engage member has a second outer diameter which is larger than the first outer diameter, such that the resilient engage member is engaged with an inner side of the sleeve, and the resilient engage member is optionally situated at an elastic deformation position, such that the detachable positioning device freely passes through the sleeve. ### Claim 4 (depends on 3) The quick detachable and adjustable magnetic seat of claim 3, wherein the magnetic device is provided with a support portion facing the connecting end; when the support portion contacts the connecting end, the spring is prevented from being completely compressed. ### Claim 5 (depends on 4) The quick detachable and adjustable magnetic seat of claim 4, wherein the magnetic device includes a magnet disposed on one end of the first axle member and provides a magnetism; the connecting end of the detachable positioning device is slidably disposed on another end of the first axle member, the first axle member is provided with a first limit portion, and the second axle member is provided with a second limit portion, and when the spring moves the magnetic device back to the original position, the first limit portion and the second limit portion prevent the spring from detaching the magnetic device from the detachable positioning device. ### Claim 6 (depends on 5) The quick detachable and adjustable magnetic seat of claim 5, wherein the detachable positioning device further includes a resisting side facing the resilient quick detach device, and the resisting side defines a third outer diameter which is larger than the first outer diameter, such that a received section is formed between the resilient quick detach device and the resisting side, and the received section is received by a protrusion ring formed on an inner side of the sleeve. ### Claim 7 (depends on 6) The quick detachable and adjustable magnetic seat of claim 6, wherein the resisting side is positioned on one end of the sliding seat away from the spring. ### Claim 8 (depends on 7) The quick detachable and adjustable magnetic seat of claim 7, wherein an outer wall of the second axle member is further provided with a third limit portion, and an inner side of the sliding seat is provided with a fourth limit portion, such that the third limit portion and the fourth limit portion conduct a blocking function and prevent the sliding seat from detaching from the second axle member toward the resilient quick detach device. ### Claim 9 (depends on 7) The quick detachable and adjustable magnetic seat of claim 7, wherein the magnetic device further includes a bear seat containing the magnet, and the bear seat and the magnet are disposed on the first axle member, the spring is disposed between the bear seat and the detachable positioning device, and the support portion is formed on the bear seat and faces the connecting end. ### Claim 10 (depends on 3) The quick detachable and adjustable magnetic seat of claim 3, wherein the resilient engage member is a C-clamp disposed on the detachable positioning device, a cross-section of the C-clamp is formed in a circular shape, the second outer diameter is defined by crossing two distal ends that are located at an outer edge of the C-clamp, and the first outer diameter is defined at a portion of the detachable positioning device adjacent to the resilient engage member. ### Claim 11 (depends on 3) The quick detachable and adjustable magnetic seat of claim 3, wherein the resilient engage member is a hook portion integrally formed on the detachable positioning device; the second outer diameter is defined as a length of a diameter with two distal ends thereof located at an outer periphery of the hook portion, and the first outer diameter is defined as a length of a diameter of a portion of the second axle member of the detachable positioning device adjacent to the resilient engage member. ### Claim 12 (depends on 3) The quick detachable and adjustable magnetic seat of claim 3, wherein the resilient engage member includes a ball member and a resilient member, the ball member and the resilient member embedded in the detachable positioning device; the second outer diameter is defined as a length of a diameter with a distal end thereof located at an outer periphery of the ball member, and the first outer diameter is defined as a length of a diameter of a portion of the second axle member of the detachable positioning device adjacent to the resilient engage member.
