[0047] In an embodiment, a spring 490 is sleeved on the connecting rod 460, and the two ends of the spring 490 are respectively connected to the pressing plate 440 and the adjusting box 430.
[0048] The spring 490 sleeved on the connecting rod 460 is connected to the pressing plate 440 and the adjusting box 430 at both ends, when the user releases the pull rod 480, the elastic force of the spring 490 can automatically reset the pressing plate 440 and the insertion rod 450, facilitating the locking operation again.
[0049] In an embodiment, the locking mechanism 300 includes a circular truncated cone-shaped connecting head 310 and a locking head 320, both of which are slidably sleeved outside the second handle 200.
[0050] The circular truncated cone-shaped connecting head 310 and the locking head 320 of the locking mechanism 300 are both sleeved outside the second handle 200, which provides a structural basis for locking the relative position of the first handle 100 and the second handle 200.
[0051] In an embodiment, one end of the circular truncated cone-shaped connecting head 310 is connected to one end of the first handle 100, and a threaded groove 311 is formed on the outer side of the circular truncated cone-shaped connecting head 310.
[0052] One end of the circular truncated cone-shaped connecting head 310 is connected to the first handle 100, and the threaded groove 311 formed on the outer side is used to cooperate with the locking head 320 to lock the position of the second handle 200, ensuring that the first handle 100 and the second handle 200 remain stable during training.
[0053] In an embodiment, the inner part of the locking head 320 is provided with a circular truncated cone groove 321 adapted to the one end of the circular truncated cone connector 310, the circular truncated cone groove 321 abuts against the outer side of the one end of the circular truncated cone connector 310, and the bottom end of the inner part of the locking head 320 is threadedly connected with the threaded groove 311.
[0054] The circular truncated cone groove 321 in the inner part of the locking head 320 abuts against the outer side of the one end of the circular truncated cone connector 310, and the bottom end is threadedly connected with the threaded groove 311, when the locking head 320 is rotated, the second handle 200 can be firmly locked in the inner part of the circular truncated cone connector 310 through the close abutment of the circular truncated cone groove 321 and the circular truncated cone connector 310, and the fastening effect of the threaded connection, preventing the first handle 100 and the second handle 200 from sliding during training and affecting the training effect.
[0055] The working principle of the stretcher for Pilates training is as follows: when in use, the user adjusts the second handle 200 to slide in the first handle 100 according to the user's own needs to the appropriate interval, and then rotates the locking head 320 in the locking mechanism 300, so that the inner circular truncated cone groove 321 abuts against the circular truncated cone connector 310, and the bottom end of the inner part of the locking head 320 is threadedly connected with the threaded groove 311 on the outer side of the circular truncated cone connector 310, so as to lock the second handle 200 at a specific position on the first handle 100, if the user needs to adjust the length of the stretching rope 500, the user pulls the pull rod 480 on one side of the adjusting box 430, the connecting rod 460 is moved, the connecting rod 460 pulls the pressing plate 440 to move upwards, the insertion rod 450 at the bottom end of the pressing plate 440 is pulled out of the insertion groove 471 on the limiting disc 470 at one end of the coil spring winding disc 422, at this time the coil spring winding disc 422 can rotate freely, according to the stretching needs, the stretching rope 500 is wound or unwound on the coil spring winding disc 422 by stretching or relaxing the foot pedal 600, the stretching rope 500 keeps a stable track under the guidance of the guide pipe 421, after adjusting to the appropriate length, the user releases the pull rod 480, the elastic force of the spring 490 makes the pressing plate 440 and the insertion rod 450 automatically reset, the insertion rod 450 is reinserted into the insertion groove 471 of the limiting disc 470, the coil spring winding disc 422 is locked, and the length of the stretching rope 500 is fixed, the user steps on the foot pedal 600, and holds the first handle 100 and the second handle 200 with both hands to perform Pilates stretching training.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
