Example Embodiment

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0023] The embodiment of the present invention provides a three-speed device with a large speed ratio that is convenient to replace parts, such as Figure 1-3 As shown, the housing 1 is included. The front surface of the housing 1 is movably connected with a box door 15 through a hinge. The front surface of the box door 15 is fixedly installed with a handle 16, and the bottom of the housing 1 is fixedly installed with a fixing plate 17. 17 is provided with fixing holes 18, the number of fixing plates 17 is four, and the four fixing plates 17 are distributed at the four corners of the bottom of the casing 1. The fixing plate 17 and fixing holes 18 are arranged to facilitate the fixed installation of the device The effect of this, thereby facilitating the use of the user, the top of the housing 1 is interspersed with a transmission rod 2, a turning rod 3, and a turning rod 4 from left to right. The surface of the turning rod 2 4 is located on the surface of the housing 1. The inner sleeve is equipped with a limit tube 20 that is adapted to the rotating rod two 4. The top of the limit tube 20 is fixedly connected with the top of the inner cavity of the housing 1, and the transmission rod 2, the rotating rod one 3 and the rotating rod two 4 are close to the shell One end of the body 1 penetrates the top of the housing 1 and extends to the inside of the housing 1. The end of the transmission rod 2 located inside the housing 1 is rotatably connected with a sleeve 5, the bottom of the sleeve 5 and the bottom of the inner cavity of the housing 1 Fixed connection, the surface of the transmission rod 2 and the inside of the housing 1 is interspersed with a gear 6; the end of the rotating rod 3 located inside the housing 1 is rotatably connected with a sleeve 7, and the bottom of the sleeve 7 is in the housing 1. The bottom of the cavity is fixedly connected, the surface of the rotating rod 3 and the inside of the housing 1 is interspersed with gear two 8, the gear one 6 and the gear two 8 mesh with each other, and the end of the rotating rod 4 located inside the housing 1 is interspersed with The card box 9, the end of the second rotating rod 4 close to the card box 9 penetrates the top of the card box 9 and extends to the inside of the card box 9. Both sides of the card box 9 are interspersed with a lever 10, and the lever 10 is close to the card box. One end of 9 penetrates one side of the card box 9 and extends to the inside of the card box 9. The surface of the rotating rod 2 4 and the inside of the housing 1 is interspersed with a gear 3 21. The gear 3 21 and the gear 2 8 mesh with each other. A turntable 19 is fixedly installed at one end of the rod 10 outside the cartridge 9. The surface of the turntable 19 is provided with anti-skid protrusions. The arrangement of the turntable 19 achieves the effect of facilitating the rotation of the clamping rod 10.
[0024] The card box 9 is provided with two slide plates 11, the surface of the slide plate 11 is in contact with the inner wall of the card box 9, and the opposite sides of the two slide plates 11 are fixedly installed with a snap ring 12, the snap ring 12 and the rotating rod 4 are located The inner surface of the cartridge 9 is in contact with the bottom of the rotating rod 2 4 is in contact with the bottom of the inner cavity of the cartridge 9, the end of the clamping rod 10 located inside the cartridge 9 is rotatably connected to the pipe body 13, and the end of the pipe body 13 away from the clamping rod 10 Fixedly connected to one side of the sliding plate 11, the surface of the clamping rod 10 and located inside the cartridge 9 is threadedly connected with a nut 14 that matches the clamping rod 10, and one side of the nut 14 is fixed to one side of the inner cavity of the cartridge 9 For connection, a spring 22 is fixedly installed on one side of the sliding plate 11 and located above and below the tube body 13, and the side of the spring 22 away from the sliding plate 11 is fixedly connected to the inner cavity of the card box 9.
