     DETAILED DESCRIPTION 
     The following further describes the technical solutions of the present disclosure with reference to the accompanying drawings and specific embodiments. 
     A golf putter for bidirectional golf putting provided by an embodiment of the present disclosure comprises a putter head  1 , a putter body  2  and handles  3 . The putter head  1  is provided with two golf putting surfaces, and the two golf putting surfaces are respectively located at two sides of a length direction of the putter head  1 . A golf putting action in any one direction of two directions of the bidirectional golf putting is completed by selecting one of the two golf putting surfaces. 
     As shown in  FIG. 1  to  FIG. 3 , in the golf putter, the putter head  1  comprises a golf putting portion  11 , a connecting portion  12 , a first weight-increasing portion  13 , a second weight-increasing portion  14  and an anti-rubbing ground ruler  15 . 
     The golf putting portion  11  is provided with a center axis (shown as X axis in the figure, i.e., a length direction of the golf putting portion  11 ). In a direction perpendicular to the length direction (i.e., a horizontal direction as shown in  FIG. 2 ), a cross section of the golf putting portion  11  is in a shape with a bigger upper portion and a smaller lower portion, such as a conical shape or a trapezoidal shape. Corresponding to the cross section in the conical shape or the trapezoidal shape, the golf putting portion  11  is provided with a top surface  111 , a bottom surface  112 , and a first side surface  113  and a second side surface  114  disposed in an inclined way. 
     The first side surface  113  and the second side surface  114  form a certain angle with a ground plumb line to form a loft of the golf putter. The golf putting portion  11  is further provided with a third side surface  115  (the side surface of the golf putting portion  11  near the connecting portion  12 ) and a fourth side surface  116  (the side surface of the golf putting portion  11  far away from the connecting portion  12 ) perpendicular to the length direction of the golf putting portion. 
     The golf putting portion  11  is provided with a first golf putting surface and a second golf putting surface. The first golf putting surface and the second golf putting surface are respectively disposed on the first side surface  113  and the second side surface  114  of the conical shape. The first side surface  113  and the second side surface  114  are symmetrically disposed with respect to a plane where a center axis of the putter body  2  and a center axis of the golf putting portion  11  are located. The first golf putting surface can be a complete plane of the first side surface  113  or can be a local portion of the first side surface  113 . For example, an anti-slip pad  16  is disposed in a center position of the first side surface  113 , and a region adhered with the anti-slip pad  16  (a gray region as shown in  FIG. 2 ) is the first golf putting surface for golf putting. The arrangement mode of the second golf putting surface is similar to that of the first golf putting surface, and the descriptions thereof are omitted herein. 
     The connecting portion  12  is fixedly connected with the third side surface  115  of the golf putting portion  11 . The connecting portion  12  comprises a cuboid connecting block  122  and a cylindrical connecting block  124 . The cylindrical connecting block  124  is fixedly connected onto an upper end surface of the cuboid connecting block  122 . The cylindrical connecting block  124  and the cuboid connecting block  122  can be processed by the same metal block. The connecting blocks  122  and  124  have the same length direction. A through hole perpendicular to the length direction is formed in the cuboid connecting block  122 . After a screw  125  penetrates through the through hole, the connecting block  122  is fixed onto the third side surface  115  of the golf putting portion  11 , and the connecting portion  12  is fixed onto the golf putting portion  11 . When the connecting portion  12  is fixed onto the third side surface  115  of the golf putting portion  11 , the cylindrical connecting block  124  is perpendicular to the top surface  111  of the golf putting portion  11  to extend upwards. The connecting portion  12  is configured to be connected with the putter body  2  to realize the connection of the putter head  1  and the putter body  2 . 
     Specifically, the connection of the putter head  1  and a lower end of the putter body  2  is realized through the cylindrical connecting block  124 . It can be understood that the connecting portion  12  only needs to be provided with two connecting blocks respectively configured to be connected with the golf putting portion  11  or to be connected with the putter body  2 , and the shape of the connecting blocks is not limited. Additionally, the connecting block connected with the putter body  2  allows the putter body  2  to relatively rotate, so as to adjust a relative angle between the putter body  2  and the golf putting portion  11  to adapt to use habits of different people. It can be understood that an included angle between a center line (Y axis in  FIG. 1 ) of the putter body  2  and the ground is a lie of the golf putter, and is influenced by a shape of the bottom surface  112 . The bottom surface  112  in the present embodiment is a plane. Therefore, during golf hitting, the lie of the golf putter can be easily mastered, and upright or flat cannot occur. 
     The first weight-increasing portion  13  is disposed on the fourth side surface  116  of the golf putting portion  11 . The first weight-increasing portion  13  comprises one or a plurality of first weight-increasing blocks  132 . A through hole (a center line of the through hole is aligned with the center line of the through hole in which the screw  125  is located) is formed in the first weight-increasing block  132 . Through a screw  134 , the first weight-increasing block  132  is disposed on the fourth side surface  116  of the golf putting portion  11 . By changing the quantity of the first weight-increasing blocks  132 , the weight and the gravity center of the putter head  1  can be adjusted. 
     The second weight-increasing portion  14  is disposed in a center position of the top surface  111 . A center line of the second weight-increasing portion  14  and a center connecting line of the third side surface  115  and/or the fourth side surface  116  are located in the same plane. The second weight-increasing portion  14  comprises one or a plurality of second weight-increasing blocks  142 . A through hole is formed in the second weight-increasing block  142 , and the second weight-increasing block  142  is disposed onto the top surface  111  of the golf putting portion  11  through a screw  144 . By changing the quantity of the second weight increasing blocks  142 , the weight and the gravity center position of the putter head  1  can be adjusted. 
     The anti-rubbing ground ruler  15  is fixedly disposed on the third side surface  115  and/or the fourth side surface  116 , and comprises anti-rubbing gaskets  152  and screws  154 . The anti-rubbing ground ruler  15  has a profile exceeding the bottom surface  112 . The profile shown in the figure is an arc-shaped profile. Additionally, the profile of the anti-rubbing ground ruler  15  protrudes out of the bottom surface  112  (is closer to the ground than the bottom surface  112 ), and protrudes out of the third side surface and the fourth side surface, so as to avoid insertion of the bottom surface  112  into the ground. 
     In the embodiment shown in the figure, two round anti-rubbing gaskets  152  are used as examples for illustration. The two anti-rubbing gaskets  152  are respectively disposed in positions of the third side surface  115  and the fourth side surface  116  near the bottom surface  112  through the screws  154 . Preferably, each anti-rubbing gasket  152  can rotate around the corresponding screw  154 , so that a contact mode between the putter head  1  and the ground is changed into rolling friction. Additionally, the anti-rubbing ground ruler can also be in other realization modes. For example, the anti-rubbing ground ruler  15  can be integrally formed with the golf putting portion  11 . 
     As shown in  FIG. 1 , in order to cooperate with bidirectional golf putting of the putter head  1 , in the present embodiment, the handles  3  of the golf putter include two handles  31  and  32 . The handle  31  and the handle  32  are respectively disposed at two opposite sides of the putter body  2 . A posture of respectively holding the handles by two hands is realized through the two handles  31  and  32 , and the bidirectional golf putting is completed. 
     As shown in  FIG. 1 , the putter body  2  comprises a first putter body  21  (an upper putter body in the figure) and a second putter body  22  (a lower putter body in the figure). The first putter body  21  and the second putter body  22  are fixedly connected, and the whole is in a slender rod shape. As an alternative solution, the first putter body  21  and the second putter body  22  are detachably connected. 
     The first putter body  21  is a lengthwise solid square rod, and is provided with a center line as shown by the Y axis in  FIG. 1  (i.e., the length direction of the first putter body  21 ). A plurality of installing holes are formed in the first putter body  21  (the upper portion of the putter body  1 ) in the length direction of the first putter body, and the installing holes are configured to install the handles  31  and  32 . By adjusting installing positions of the handles  31  and  32 , the distance from the two handles  31  and  32  to the putter head  1  can be changed, and the shaft length of the golf putter is adjusted, so as to be adapted to people with different body heights or different use habits. 
     Preferably, the installing holes formed in the first putter body  21  include first installing holes  26  and second installing holes  27 . The upper portion of the putter body  1  (the upper putter body  21  in the figure) is provided with four installing surfaces perpendicular to each other. A plurality of first installing holes  26  are correspondingly formed in one pair of parallel installing surfaces  260 . A plurality of second installing holes  27  are correspondingly formed in the other pair of parallel installing surfaces  270 . The first installing holes  26  and the second installing holes  27  respectively have different hole diameters. The plurality of first installing holes  26  and the plurality of second installing holes  27  are disposed in an intersecting way in positions of the putter body with different shaft lengths. The two handles  31  and  32  can be disposed on the first installing holes  26  or the second installing holes  27 , so as to realize more flexible length change of the golf putter. Herein, arrangement in an intersecting way refers to a condition that the first installing holes  26  and the second installing holes  27  are located in different horizontal planes (the direction perpendicular to the center line of the first putter body  21 ). That is, the first installing holes  26  and the second installing holes  27  are located in different planes and have different heights. 
     The second putter body  22  (the lower putter body in the figure) is a hollow round pipe. An upper end of the second putter body  22  is fixed to a lower portion of the first putter body  21 . The lower end of the second putter body  22  is configured to be connected with the cylindrical connecting block  124 . It can be understood that the second putter body  22  can also be a structure integrally formed with the first putter body  21 . A groove configured to accommodate the cylindrical connecting block  124  is processed in the lower end of the second putter body  22 , so as to realize the connection between the second putter body  22  and the connecting portion  12 . 
     By rotating the second putter body  22  in the round pipe shape, a relative position relationship of the first installing holes  26  and the second installing holes  27  in the putter body and the putter head  1  can be changed, so that at least one of the first installing holes  26  or at least one of the second installing holes  27  is perpendicular to the length direction of the putter head  1  (X axis). The two handles  31  and  32  are disposed in the installing holes perpendicular to the length direction of the putter head  1 , so that a connecting line of the two handles  31  and  32  is perpendicular to the length direction of the putter head  1 , and is also perpendicular to the length direction of the putter body  2 . That is, the connecting line of the handles  31  and  32  is perpendicular to the plane where the center axis of the putter head  1  and the center axis of the putter body  2  are located (the plane where the X axis and the Y axis are located in  FIG. 1 ). 
     By using the golf putter through the posture of respectively holding the handles by two hands, a user can do golf putting to the left side or the right side on the premise of not changing a holding posture. The golf putting direction is not limited, and the golf putter is respectively applicable to the users with left-hand or right-hand putting habits. 
     Of course,  FIG. 4  further provides another use mode of the golf putter. The installing holes at different heights are formed in different planes of the first putter body  21 , and the first putter body  21  can rotate relative to the golf putting portion  11 , so that another holding posture of holding the handles by two hands can be realized by installing the two handles  31  and  32  into the installing holes parallel to the length direction of the putter head  1 , and another possibility is provided for the use of the golf putter. 
     The two handles  31  and  32  and the connecting mode of the two handles and the putter body  2  (the first putter body  21 ) are exemplarily illustrated below in conjunction of  FIG. 5  and  FIG. 6 . 
     As shown in  FIG. 5  and  FIG. 6 , the two handles  31  and  32  are respectively disposed at opposite sides of the putter body  2 . A connecting line of the two handles  31  and  32  is perpendicular to the length direction of the putter body  2 .
