Further improved, the concave steel sleeve structure of the second connecting portion 12 and the convex joint 121 are of a split structure adopting threaded connection, which is beneficial to processing, convenient to install and beneficial to adjusting the distance between the first connecting portion and the second connecting portion.
The elbow joint 1 structure is adopted in both left and right elbow joint parts of the wrestling dummy, and the joint structure is adopted in both left and right knee joint 2 parts of the wrestling dummy, so that the same activity effect as that of a real knee joint is realized.
Referring to fig. 4 and 5, the specific structure of the hip joint 3 in this embodiment is: comprising a third connection portion 31, a fourth connection portion 32 and a fifth connection portion 33.
One end of the third connecting part 31 is a protruding joint 311, the protruding joint 311 is used for being connected with the fourth connecting part 32, and the other end of the third connecting part 31 is used for being fixedly connected with the third anthropomorphic bone 7.
The fourth connecting portion 32 includes a first steel sleeve 321, a second steel sleeve 322, steel balls 323, steel spherical crown gaskets 324, elastic pieces 325, and steel rods 326. One end of the first steel sleeve 321 is provided with a through hole in threaded connection with one end of the steel rod 326, and an elastic piece 325, namely a pressure spring, is arranged inside the first steel sleeve 321. The steel ball 323 is propped against the elastic piece 325 through the steel ball crown gasket 324 and is arranged at the other end of the first steel sleeve 321, the open end of the second steel sleeve 322 is connected with the open end of the first steel sleeve 321 through threads, a limiting through hole 327 for exposing the steel ball 323 is arranged on the contact surface of the second steel sleeve 322 and the steel ball 323, and the limiting through hole 327 is a circular hole and is closely attached to the steel ball 323. The exposed portion of the steel ball 323 is provided with a concave hole, and the concave hole is in threaded connection with the convex joint 311 of the third connecting portion 31.
The extrusion degree of the steel ball 323 and the steel spherical crown gasket 324 to the pressure spring can be adjusted through threads by the second steel sleeve 322, and the control of the rotation force of the steel ball can be realized through different extrusion degrees of the pressure spring, so that the control of the rotation force of the joint is realized.

In a more preferred embodiment, referring to fig. 7, the second steel sleeve 322 is further provided with a limiting sphere 328 matching with the sphere of the steel ball along a part of the edge of the limiting through hole 327, so that when the protruding joint 311 of the third connecting portion 31 contacts the edge of the limiting sphere 328, the rotation angle of the steel ball 323 is limited, and the arm is truly reflected to move towards the back of the human body without limitation, so as to achieve the same effect as the rotation angle of the arm of the human body. Therefore, when a user performs joint skill training, pressure is applied to the joint in the opposite direction, and the real experience of breaking the joint and better training effect can be achieved.
When the arm of the dummy is pressed down in the lower body direction of the dummy by an external force, for example, the arm moves down, and since the third connection part 31, the bump connector 311, and the steel ball 323 are connected, the third connection part 31, the bump connector 311, and the steel ball 323 also follow the downward movement. When the bottom edge of the protruding joint 311 touches the second steel sleeve 322, the second steel sleeve 322 is forced to move downwards, and the second steel sleeve 322, the first steel sleeve 321 and the steel rod 326 are connected with the steel balls of the second fourth connecting part, so that the whole of the first fourth connecting part and the steel balls of the second fourth connecting part move downwards, and when the bottom edge of the steel rod 326 touches the second steel sleeve of the second fourth connecting part, the dummy arm is pressed down because the second fourth connecting part is connected with the fifth connecting part 33 and the dummy collarbone, and the dummy collarbone is tightly wrapped by cotton cloth and does not move. Similarly, the arms of the dummy can move in all directions, and when the arms move backwards, the arms of the dummy can be blocked by the limiting spherical surface, so that the arms of the dummy can be limited to a certain extent, and the shoulder joints of a human body can be simulated more truly.
Referring to fig. 8, the wrestle dummy according to the present embodiment is further provided with a stainless steel bellows 10 outside the elbow joint 1, the knee joint 2, the hip joint 3, and the shoulder joint 4, and both ends of the stainless steel bellows 10 are connected to leather 9 on both sides thereof, respectively, to form a complete and good-looking dummy. The stainless steel bellows 10 functions as: firstly, the protective sleeve is used for protecting a user from being impacted by a part at a joint; and secondly, because the stainless steel corrugated pipe is moderate in elasticity and resistant to external force, when the dummy arm is rotated along the axial direction of the arm shaft, the dummy arm can not rotate by a certain angle, and therefore, the dummy arm is the same as the arm of a person, can not rotate by any angle, is resistant to external force and is not easy to damage, and meanwhile, has elasticity, so that the shoulder joint can be stretched at will.
The dummy for wrestling is used for simulating the dummy for wrestling training, so that the joint swing range and the rotation range of the dummy are consistent with the moving range of a true person, the dummy has the same joint flexibility as the true person, a trainer can perform better training, and the wrestling training effect is greatly improved. The wrestling dummy can integrate the wrestling dummy and jujitsu dummy, a trainer can simultaneously perform wrestling and jujitsu during training, and jujitsu joint locking technology is added during the wrestling process, and wrestling skills are also used during the locking technology training, so that the training effect is doubled. Namely, the wrestling dummy allows the user to use less price and has two functions, and the wrestling dummy does not occupy space and has good application prospect.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present invention.
