It allows the user to pull out the paper roll with one hand and avoids rattling during the process of pulling out the paper roll. ## Claims ### Claim 1 A paper towel holder, comprising: a support base; a support shaft, which is provided on the support base, and is used to rotatably cooperate with a center hole of a paper roll to support the paper roll and enable the paper roll to rotate around the support shaft; a movable clamping body, which is movably sleeved on a first end of the support shaft along a length direction of the support shaft, and is used to abut against a first end of the paper roll; a static clamping body, which is detachably arranged on a second end of the support shaft, and is used to abut against a second end of the paper roll; a first magnetic suction member, which is arranged on the movable clamping body; and a second magnetic suction member, which is arranged on a side proximate to the first end of the support shaft and further away from the static clamping body than the movable clamping body, wherein the second magnetic suction member and the first magnetic suction member repel each other so as to maintain the movable clamping body in a state of being held against the first end of the paper roll; or, the second magnetic suction member is arranged on a side proximate to the second end of the support shaft, the second magnetic suction member and the first magnetic suction member attract each other so as to maintain the movable clamping body in a state of being held against the first end of the paper roll. ### Claim 2 (depends on 1) The paper towel holder according to claim 1, wherein the first magnetic suction member and the second magnetic suction member are both annular structures arranged around the support shaft. ### Claim 3 (depends on 1) The paper towel holder according to claim 1, wherein the second end of the support shaft has a socket, which extends along the length direction of the support shaft; the static clamping body comprises an inserting portion, the inserting portion and the socket fit together to connect the static clamping body and the support shaft together. ### Claim 4 (depends on 3) The paper towel holder according to claim 3, wherein the support shaft is provided with a first snap portion, the first snap portion is arranged in the socket; the inserting portion is provided with a second snap portion, the second snap portion and the first snap portion are detachably snapped together, the second snap portion and the first snap portion are snapped together to restrict the inserting portion from disengaging from the socket. ### Claim 5 (depends on 4) The paper towel holder according to claim 4, wherein the second snap portion is radially movably arranged on the inserting portion; said static clamping body further comprises a static seat body having the inserting portion and a press-type drive structure movably arranged on the static seat body, the press-type drive structure is connected to the second snap portion, the press-type drive structure has a relaxation state and a pressing state, the second snap portion and the first snap portion are snapped together, when the press-type drive structure is in the relaxation state; the second snap portion and the first snap portion are disengaged, when the press-type drive structure is in the pressing state. ### Claim 6 (depends on 5) The paper towel holder according to claim 5, wherein the press-type drive structure comprises: a press portion, which is radially movably arranged on the static seat body, the press portion and the second snap portion are connected; a resilient member, which is arranged between the press portion and the static seat body, the resilient member is used to drive the press portion to reset from the pressing state to the relaxation state. ### Claim 7 (depends on 4) The paper towel holder according to claim 4, wherein the paper towel holder further comprises a connecting cylinder, the connecting cylinder is inserted in the socket, an end of the connecting cylinder far away an outer end of the socket forms the first snap portion; the second snap portion has a snap slot, the snap slot and the first snap portion are snapped together. ### Claim 8 (depends on 1) The paper towel holder according to claim 1, wherein the support shaft is provided with a position limiting structure, the position limiting structure and the movable clamping body abut against each other, to limit a movement of the movable clamping body in a direction proximate to the static clamping body. ### Claim 9 (depends on 1) The paper towel holder according to claim 1, wherein in case of that the second magnetic suction member is arranged on a side proximate to the first end of the support shaft and further away from the static clamping body than the movable clamping body, the first end of the support shaft is also provided with a fixing seat and the second magnetic suction member is arranged on the fixing seat; or, in the case of that the second magnetic suction member is located on a side close to the second end of the support shaft, the second magnetic suction member is provided on the static clamping body. ### Claim 10 (depends on 1) The paper towel holder according to claim 1, wherein a side of the movable clamping body proximate to the static clamping body is provided with a first tapered portion, the first tapered portion has a cross-section that tapers in the direction proximate to the static clamping body, the first tapered portion is used to partly abut against the first end of the paper roll; a side of the static clamping body proximate to the movable clamping body is provided with a second tapered portion, the second tapered portion has a cross-section that tapers in the direction proximate to the movable clamping body, the second tapered portion is used to partly abut against a second end of the paper roll.
