[0024] The second end of the counterweight 3 is inwardly formed with a groove 12, the pressing pad 10 and the groove 12 are longitudinally connected with the spring 9.

[0025] It is worth noting that when the counterweight 3 has not been inserted into the connecting groove 2, the clamping bead 5 is arranged in the through hole 8 and partially exposed outside the through hole 8, when it is necessary to be inserted into the connecting groove 2, the pressing pad 10 is first pressed, the pressing component 4 is vertically downward, the spring 9 is deformed, the clamping bead 5 is pulled out of the through hole 8 by the pressing component 4, and then the counterweight 3 is straightly inserted into the connecting groove 2, the pressing component 4 is vertically upward reset by the rebound force of the spring 9, the clamping bead 5 is also driven to return to the through hole 8, because the lateral wall of the inclined part 42 is inclined, the inclined surface has an extrusion force on the clamping bead 5, so that the clamping bead 5 can be fixed in the bead groove 6.

[0026] Of course, the loading and unloading structure of the utility model also includes a counterweight clamp, which aims to prevent the counterweight from falling off after the counterweight disc is sleeved on the counterweight body.

[0027] Specifically, in combination with Figures 2-4 The counterweight clamp includes a first sleeve 12 sleeved on the end of the bodybuilding rod and a second sleeve 13 sleeved on the outside of the first sleeve 12, the first end of the first sleeve 12 gradually decreases in diameter from the first end to the second end, the outer wall of the first sleeve 12 is a slope, the inner wall of the second sleeve 13 is attached to the slope, and the inner wall of the first sleeve 12 is provided with a limiting assembly for limiting the bodybuilding rod after the bodybuilding rod is sleeved in place in the first sleeve 12.

[0028] In actual use, after the weight piece is sleeved on the bodybuilding rod 1, the small-diameter side of the first sleeve 12 is aligned with the bodybuilding rod, so that the bodybuilding rod 1 is slowly inserted into the first sleeve 12, and after a certain degree, the limiting device limits the bodybuilding rod to prevent the weight piece from falling off.

[0029] The limiting assembly includes a plurality of limiting balls 14, and the inner wall of the first sleeve 12 is radially provided with a plurality of channels for corresponding sliding of the plurality of limiting balls 14, and the channels penetrate the inner and outer walls of the first sleeve 12.

[0030] The limiting balls 14 partially protrude outside the channels, and after the bodybuilding rod is sleeved in place in the first sleeve 12, the limiting balls 14 are respectively attached to the bodybuilding rod and the inner wall of the second sleeve 13.

[0031] After aligning the small-diameter end of the first sleeve 12 with the bodybuilding rod, the bodybuilding rod is inserted inward, and by operating the second sleeve 13 to slide relative to the first sleeve 12, the limiting balls 14 are retracted into the channels, so that the bodybuilding rod can be continuously inserted inward, and after reaching the specified position, the first sleeve 12 abuts against the bodybuilding rod, and after the bodybuilding rod is completely sleeved, since the first end of the first sleeve 12 decreases in diameter from the first end to the second end, i.e., the inner and outer walls of the first sleeve 12 are slopes, the limiting balls 14 are simultaneously extruded by the bodybuilding rod and the inner wall of the second sleeve 13, and the limiting balls 14 have an opposite force on the bodybuilding rod to further stabilize the bodybuilding rod 1. When disassembly is needed, only the inner wall of the second sleeve 13 needs to be slid along the slope of the outer wall of the first sleeve 12 in the direction of the small diameter of the first sleeve 12, so that the distance between the limiting balls 14 and the outer wall of the second sleeve 13 will be increased, thereby eliminating the extrusion on the bodybuilding rod to achieve disassembly.

[0032] It is worth noting that the limiting balls 14 can also be connected to the channels by springs, and after being extruded by the bodybuilding rod, the limiting balls 14 exert pressure on the bodybuilding rod by the reaction of the spring force to achieve anti-skid.

[0033] The first end of the first sleeve 12 is provided with a hand-held portion 15.

[0034] In actual operation, the hand-held part 15 can be held to perform subsequent operations to achieve the purpose of saving labor.
