As shown in FIG. 3, the front end of each handle fixing seat 112 is connected to the bottom of the screw seat 113. The handle holder 112 may be hollow cylindrical. The screw base 113 has a housing 1130, and the housing 1130 has a receiving space 1133 therein. The surface of the housing 1130 has threads 1131, and the threads 1131 have one or more openings 1132 along the axial direction of the threaded seat 113. In this embodiment, the number of the openings 1132 is four, but is not limited thereto.

Fig. 4 is a partially enlarged view illustrating the assembly of the spring 100 with the handle fixing seat 112 and the screw seat 113 of the multifunctional strength training device 1 according to the first embodiment of the present invention. As shown in fig. 4, the threaded socket 113 may be threaded 1131 into one end of the spring 100. In addition, the threaded seat 113 has a stop 1134, and the threaded seat 113 cannot penetrate further into the spring 100 after the stop 1134 of the threaded seat 113 screwed into the spring 100 abuts against the spring 100.

As shown in fig. 4, the outer diameter of the threaded socket 113 can be reduced by the one or more openings 1132. Therefore, the screw base 113 can be smoothly screwed into or out of the spring 100. In the present embodiment, the outer diameter of the thread 1131 of the threaded seat 113 may be equal to or slightly larger than the inner diameter of the spring 100. In a preferred embodiment, the material of the threaded seat 113 may be plastic. In another embodiment, the material of the threaded seat 113 may be rubber.

Fig. 5 is a partially enlarged view illustrating the assembly of the spring 100 with the handle fixing seat 112 and the screw seat 113 of the multifunctional strength training device 1 according to the first embodiment of the present invention. As shown in fig. 5, after the screw base 113 is screwed into the spring 100 to the positioning stop point 1134, the pressing unit 116 can be inserted into the inlet end 1121 of the handle fixing base 112, and the pressing unit 116 is inserted into the accommodating space 1133 of the screw base 113, so that the opening 1132 of the screw base 113 is expanded.

As shown in fig. 10, the threaded socket 211 has a housing 2111, the housing 2111 has a receiving space 2115 therein, the surface of the housing 2111 has threads 2113, and the threads 2113 have one or more openings 2110 along the axial direction of the threaded socket 211. In the present embodiment, the number of the openings 2110 is four, but is not limited thereto.

Fig. 11 is a partially enlarged view illustrating the assembly of the spring 200 and the screw holder 211 of the multifunctional force exerciser 2 according to the second embodiment of the present invention. As shown in FIG. 11, the threads 2113 of the threaded seat 211 may be threaded into one end of the spring 200. In addition, the screw seat 211 has a positioning stopping point 2112, and after the positioning stopping point 2112 of the screw seat 211 screwed into the spring 200 abuts against the spring 200, the screw seat 211 cannot penetrate into the spring 200.

As shown in fig. 11, the one or more openings 2110 allow the outer diameter of the threads 2113 of the threaded seat 211 to be compressed to be smaller. Therefore, the screw holder 211 can be smoothly screwed into or out of the spring 200. In a preferred embodiment, the material of the threaded seat 211 may be plastic. In another embodiment, the material of the screw seat 211 may be rubber. In this embodiment, the accommodating space 2115 of the screw seat 211 may have a square hollow structure.

Fig. 12 is a partially enlarged view illustrating the assembly of the spring 200 and the screw holder 211 of the multifunctional force exerciser 2 according to the second embodiment of the present invention. As shown in fig. 12, after the thread 2113 of the screw seat 211 is screwed into the spring 200 to the positioning middle dead point 2112, the pressing unit 214 is placed, and the pressing unit 214 is inserted into the accommodating space 2115 of the screw seat 211, so that the opening 2110 of the screw seat 211 is spread. In the present embodiment, the pressing unit 214 has a square shape, a solid or a hollow tubular shape. In the present embodiment, the pressing unit 214 is made of metal.

As shown in fig. 12, an important feature of the present invention is that after the pressing unit 214 is inserted into the screw seat 211, the outer diameter of the screw seat 211 becomes fixed and cannot be compressed to become small, so that the screw seat 211 cannot be withdrawn from the spring 200. At this time, if it is desired to rotate the screw seat 211 to withdraw the spring 200, the reverse torsion of the spring 200 will make the inner diameter of the spring 200 contract and become smaller, thereby locking the screw 2113 of the screw seat 211, so that the screw seat 211 cannot move.

As shown in fig. 8, 9 and 12, the pressing unit 214 further passes through the square hole 2120 of the handle holder 212, and the handle holder 212 is disposed in the handle 213. In addition, the two large wheels 215 are respectively disposed on the left and right sides of the grip 213, and the pressing units 214 respectively pass through the square holes 2160 of the two connection plates 216 disposed on the both sides of the large wheels 215 and the square holes 2190 of the wheel inner tube 219 disposed at the axial center of the large wheels 215. In addition, the pressing unit 214 may also pass through the square hole 2100 formed in the rear end inner tube 210. In addition, the coupling hole 2182 of the hook 218, the coupling hole 2102 of the trailing end inner tube 210, and the coupling hole 2140 of the pressing unit 214 may be coupled by a first coupling member 2180, such as a C-shaped pin. In addition, the connection hole 2114 of the screw socket 211 and the connection hole 2142 of the pressing unit 214 may be connected by a second connection member 2116, such as a screw.

As shown in fig. 8, 9 and 12, the second end of the connecting plate 216 on both sides of each large wheel 215, i.e. the end near the small wheel 217, has a slot 2162, and the axle center of the small wheel 217 is pivoted in the slot 2162. Thereby, the axle center of the small wheel 217 can move in the groove 2162. The assembled multifunctional exerciser 2 is shown in fig. 7. When the moving direction is that the large wheel 215 is in front and the small wheel 217 is in back, the axle center of the small wheel 217 moves to one end far away from the large wheel 215 in the groove 2162, so that the small wheel 217 is far away from the large wheel 215, and therefore the small wheel 217 does not obstruct the rolling of the large wheel 215. When the moving direction is that the large wheel 215 is at the back and the small wheel 217 is at the front, the axle center of the small wheel 217 moves to the end of the groove 2162 close to the large wheel 215, so that the small wheel 217 contacts the large wheel 215 and generates resistance to prevent the large wheel 215 from rolling. In this embodiment, the square pressing unit 214 can ensure the connection plate 216 has a uniform direction, so that the large wheel 215 and the small wheel 217 can operate smoothly.

The multifunctional strength exerciser 1 or 2 provided by the embodiment of the invention has the advantages of few parts, high reliability, convenience in maintenance and the like, and is quick to assemble.
