The first inclined surface 308 and the second inclined surface 3013 can rub against each other, so that the block 307 slides into the cavity under the squeezing and friction of the block 3012, thereby facilitating the pressing of the block 3012 into the groove 306. The slide groove 101 and the slider 201 can play a limiting role, so that the placement rack 2 can perform a linear sliding movement.

[0038] Example 3

[0039] like Figure 1-6As shown, on the basis of Example 1 and Example 2, the utility model provides a technical solution: preferably, a thread groove 202 is provided at the bottom of the placement frame 2, the bottom of the cart 1 is fixedly connected with a support block 103, the inner through-bearing of the support block 103 is movably connected with a bidirectional threaded rod 6, the placement frame 2 is threadedly engaged with both ends of the bidirectional threaded rod 6 through the thread groove 202, the bottom of the support block 103 is fixedly connected with a fixing plate 104, the inside of the fixing plate 104 is provided with a driving device 4, the driving device 4 includes a driving motor 401, the driving motor 401 is provided with an inner part of the fixing plate 104, and the fixing plate 1 04 is fixedly connected to a limit block 105 on the inner side, and the end of the limit block 105 away from the fixed plate 104 is movably connected to a rack 5, one side of the rack 5 is fixedly connected to a guide rail 501, and a guide groove is provided at the end of the limit block 105 away from the fixed plate 104, and the rack 5 forms a slidable structure through the guide rail 501, the guide groove and the limit block 105, the output shaft of the drive motor 401 is fixedly connected to the first gear 402 through a coupling, and the middle position of the bidirectional threaded rod 6 is fixedly connected to the second gear 601, the second gear 601 is meshed with the rack 5, and the bottom of the rack 5 is meshed with the first gear 402.

[0042] like Figure 1-6As shown, the crankshaft assembly is placed on the upper end of the lower jacket 301, and then the upper jacket 303 is bent and rotated around the rotating shaft 302, so that the block 3012 is pressed into the inside of the slot 306. During the process, the first inclined surface 308 and the second inclined surface 3013 will rub against each other, so that the block 307 slides into the cavity under the extrusion and friction of the block 3012 and drives the return spring 3011 to compress. When the block 3012 is completely pressed into the inside of the slot 306, the return spring 3011 drives the block 307 to reset. The crankshaft assembly can be clamped and fixed by the stopper 307, so that the stopper 307 can stop the block 3012 inside the slot 306, thereby fixing the lower jacket 301 and the upper jacket 303 together. When the length needs to be adjusted, the first gear 402 is driven to rotate by the driving motor 401, and the rack 5 is driven to slide in a straight line, thereby driving the second gear 601 to drive the bidirectional threaded rod 6 to rotate and drive the placement frame 2 to move relatively under the action of the thread groove 202 being threadedly engaged with the two ends of the bidirectional threaded rod 6, so as to achieve the problem of adjusting the length.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
