Referring to fig. 7 and 8 again, the limiting mechanism 7 comprises a rack 75 fixedly connected to one side of the sliding rail 60 facing the installation cavity 610, wherein the length of the rack 75 is the same as that of the sliding rail 60, a communicating groove 611 for accommodating the rack 75 and communicating with the installation cavity 610 is formed in one side of the sliding block 61, so that when the sliding block 61 and the sliding rail 60 slide mutually, the rack 75 does not interfere with the sliding block 61, a rotating shaft 76 is vertically arranged in the installation cavity 610 along the height direction of the installation cavity 610, a limiting groove 612 for accommodating the lower end part of the rotating shaft 76 is formed in the bottom surface of the installation cavity 610, a supporting spring 77 for supporting the rotating shaft 76 is placed in the limiting groove 612, a driven gear 78 is coaxially fixedly connected to the rotating shaft 76, in an initial state, the rotating shaft 76 is supported by the supporting spring 77, a gap is reserved between the driven gear 78 and the bottom surface of the installation cavity 610, and the driven gear 78 are mutually meshed with the rack 75, and when the sliding block 61 and the sliding rail 60 slide mutually, the driven gear 78 is driven by the mutual meshing of the rack 75 and the driven gear 78.
Referring to fig. 9 and 10, six hemispherical limit protrusions 79 are uniformly and fixedly connected to the lower surface of the driven gear 78 around the center of the driven gear 78, a matching groove 613 for accommodating the limit protrusions 79 is formed in the bottom surface of the installation cavity 610 at positions corresponding to the six limit protrusions 79, and a driving mechanism 8 for driving the rotation shaft 76 to move down to insert the limit protrusions 79 into the corresponding matching grooves 613 so as to limit the rotation of the driven gear 78 is further provided in the balancing weight 62, and the matching state of the limit protrusions 79 and the matching grooves 613 can be known with reference to fig. 10 and 11.
Referring to fig. 9 and 10, the weight 62 includes a housing 620 and a weight unit 621 inserted into the housing 620, an upper end of the rotation shaft 76 penetrates into the housing 620 and is slidably coupled to the housing 620, the driving mechanism 8 includes a rotation roller 80 provided in the housing 620 and rotatably coupled to an inner wall of the housing 620, the rotation roller 80 is positioned right above the rotation shaft 76 such that an upper end surface of the rotation shaft 76 is always abutted against an outer circumferential surface of the rotation roller 80, and an extension line of an axis of the rotation shaft 76 is perpendicular to and interfered with an axis of the rotation roller 80, a tangential surface 800 is formed on a circumferential surface of the rotation roller 80 along a length direction of the rotation roller 80, thereby reducing a radius of a portion of the rotation roller 80, and an upper end of the rotation shaft 76 is abutted against the tangential surface 800 of the rotation roller 80 when the rotation shaft 76 is in an initial state, so that the support spring 77 is in a natural state.
Referring to fig. 7 and 12, a driving assembly 9 for driving the rotating roller 80 to rotate is further arranged at one end of the rotating roller 80, the driving assembly 9 comprises a transmission gear 90 coaxially fixedly connected to one end of the rotating roller 80, a driving gear 91 meshed with the transmission gear 90 is rotatably connected to the side wall, where the shell 620 is abutted against, of the side wall, where the driving gear 90 is abutted against, of the shell 620, a rotary table 92 coaxially fixedly connected with the driving gear 91 is arranged on the outer wall of the shell 620, the rotary table 92 is rotatably connected with the outer wall of the shell 620, and a holding handle 93 is fixedly connected to one side, away from the driving gear 91, of the rotary table 92, so that a user can drive the rotary table 92 to rotate through the holding handle 93, and further realize rotation of the rotating roller 80 through meshed transmission of the driving gear 91 and the transmission gear 90.
Referring to fig. 9, a relief groove 622 is formed at a position where the lower surface of the weight unit 621 interferes with the rotating roller 80 and the driving assembly 9, so that after the weight unit 621 and the housing 620 are inserted into each other, the normal operation of the driving mechanism 8 is not affected, and a user can maintain the driving mechanism 8 through the disassembly of the weight unit 621, thereby improving the maintenance efficiency.
The embodiment 2 is implemented by the principle that when the user uses the balancing weight 62, the holding handle 93 can be held and drives the balancing weight 62 to slide on the sliding rail 60, at this time, the driven gear 78 freely rotates in the mounting cavity 610 under the mutual engagement with the rack 75, when the user needs to fix the sliding relative position of the sliding block 61 and the sliding rail 60, the user can rotate the holding handle 93 and drive the turntable 92 to rotate and drive the rotating roller 80 to rotate through the mutual engagement of the driving gear 91 and the transmission gear 90, at the initial state of the rotating shaft 76, the upper end of the rotating shaft 76 is positioned at the tangent plane 800 of the rotating roller 80, along with the rotation of the rotating roller 80, the rotating shaft 76 is enabled to move towards the bottom of the limiting groove 612 under the limit of the limiting groove 612 and drive the supporting spring 77 to compress elastically, at the same time, the limiting protrusion 79 on the lower surface of the driven gear 78 is blocked in the corresponding matching groove 613, thus limiting the free rotation of the driven gear 78, at this time, the state that the driven gear 78 also keeps the mutual engagement with the sliding block 75 is limited, the sliding relative sliding of the sliding block 61 and the sliding rail 60 is limited, and the user only needs to fix the sliding rail 60 relative position of the holding handle 62 on the rack 60.
