Magnetic stick and magnetic toy

Abstract

A magnetic stick includes: a magnetic stick body; two pressing pieces, respectively and movably clamped at two ends of the magnetic stick body, where a part of each of the pressing pieces protrudes out of the magnetic stick body, and the part of one pressing piece protruding out of the magnetic stick body moves towards the other pressing piece when being pressed; and an elastic piece, arranged in the magnetic stick body, where two ends of the elastic piece respectively abut against the pressing pieces and the magnetic stick body, and the elastic piece is compressed when being pressed by the pressing pieces.

What is claimed is: 
     
         1 . A magnetic stick, comprising:
 a magnetic stick body;   two pressing pieces, respectively and movably clamped at two ends of the magnetic stick body, wherein a part of each of the pressing pieces protrudes out of the magnetic stick body, and   the part of one pressing piece protruding out of the magnetic stick body moves towards the other pressing piece when being pressed; and   an elastic piece, arranged in the magnetic stick body, wherein two ends of the elastic piece respectively abut against the pressing pieces and the magnetic stick body, and the elastic piece is compressed when being pressed by the pressing pieces.   
     
     
         2 . The magnetic stick according to  claim 1 , further comprising:
 a connecting shell, arranged at an end part of the magnetic stick body, wherein an accommodating groove for accommodating the pressing pieces is formed in the connecting shell, a groove wall of the accommodating groove is inwards convexly provided with a protruding part, a maximum diameter of the pressing pieces is greater than an inner diameter of the protruding part, the protruding part is configured to block the pressing pieces so as to prevent the pressing pieces from falling out of the accommodating groove,   the elastic piece is located in the accommodating groove, and two ends of the elastic piece respectively abut against the pressing pieces and a groove bottom of the accommodating groove.   
     
     
         3 . The magnetic stick according to  claim 2 , wherein the connecting shell comprises:
 an accommodating part, arranged at the end part of the magnetic stick body and provided with a mounting groove; and   a connecting part, arranged at a notch of the mounting groove, connected to a groove wall of the mounting groove and provided with a through hole, the through hole and the mounting groove forming the accommodating groove, and   the protruding part being formed on a hole wall of the through hole.   
     
     
         4 . The magnetic stick according to  claim 3 , wherein the two pressing pieces are of spherical structures. 
     
     
         5 . The magnetic stick according to  claim 3 , wherein one pressing piece is of a spherical structure and the other pressing piece is of a rotating structure; and the rotating structure rotates in a direction perpendicular to an axis of the magnetic stick body. 
     
     
         6 . The magnetic stick according to  claim 5 , wherein each of the pressing pieces comprises:
 a pressing part, a part of the pressing part protruding out of the accommodating groove;   a rotating part, arranged on a side surface of the pressing part and located in the accommodating groove, a maximum diameter of the rotating part being greater than the inner diameter of the protruding part, and the rotating part being configured to: when the pressing pieces reset, slide along the hole wall of the through hole and rotate in the direction perpendicular to the axis of the magnetic stick body; and   a pushing part, arranged in the accommodating groove, one end of the pushing part being connected to the pressing part and the other end of the pushing part abutting against the elastic piece.   
     
     
         7 . The magnetic stick according to  claim 3 , wherein an edge position of the elastic piece abuts against a groove bottom of the mounting groove, and a gap is formed between a position of the elastic piece abutting against the pressing pieces and the groove bottom of the mounting groove. 
     
     
         8 . The magnetic stick according to  claim 3 , wherein the accommodating groove comprises:
 a connecting groove, a groove wall of the connecting groove being connected to the connecting part; and   a limiting groove, connected to the connecting groove, a size of the limiting groove being matched with that of the elastic piece, and the limiting groove being configured to accommodate the elastic piece and limit the position of the elastic piece so as to prevent the elastic piece from shaking.   
     
     
         9 . The magnetic stick according to  claim 1 , wherein the magnetic stick body comprises:
 a magnetic attraction piece;   two attracted pieces, adsorbed at two ends of the magnetic attraction piece, the two pressing pieces being respectively arranged at ends of the two attracted pieces away from each other; and   a sleeve, arranged at the peripheries of the magnetic attraction piece and the two attracted pieces and configured to protect the magnetic attraction piece and the attracted pieces.   
     
     
         10 . A magnetic toy, comprising at least two magnetic sticks according to  claim 1 , wherein the at least two magnetic sticks are capable of being magnetically attached together.
