Detailed Implementation

[0018] like Figures 1 to 5 As shown, this utility model discloses a transmission support device. The technical solution adopted includes a support mechanism 5, a clamping mechanism 2 slidably connected to the support mechanism 5, a rotating mechanism 3 rotatably connected to the clamping mechanism 2, an adjusting mechanism 4 meshing at the other end of the clamping mechanism 2, and a transmission shaft 1 clamped between the rotating mechanisms 3.

[0019] As a preferred technical solution of this utility model, such as Figures 1 to 5As shown, the support mechanism 5 includes a base 504 with an arc-shaped notch. A storage groove 503 is located below the arc-shaped notch. A support ring 501 is located on the arc-shaped notch. Three guide openings 502 are arranged in a circular array on the support ring 501. A rack 201 is slidably connected within each guide opening 502. An arc-shaped groove 202 is located at the bottom of the rack 201. One end of the arc-shaped groove 202 has a through-hole lug 203 with a threaded interior, and the other end has a countersunk lug 204 connected to the outer diameter of a bearing 308. The inner diameter of the bearing 308 is connected to a fixing clamping block 305. A fixing shaft 306 is located in the middle of the fixing clamping block 305. The fixed clamping block 305 is provided with a fixed boss 307. There are three fixed bosses 307 arranged in a circular array on the fixed clamping block 305. The fixed clamping block 305 is engaged with the fixed hole 302 and the fixed groove 303 on the roller 301 through the fixed shaft 306 and the fixed bosses 307. The roller 301 is engaged with the movable clamping block 304 through this engagement. The movable clamping block 304 is connected to the inner diameter of the bearing 308. The outer diameter of the bearing 308 is connected to the threaded shaft 310. One end of the threaded shaft 310 has a knob with anti-slip texture, and the other end has a countersunk hole that engages with the outer diameter of the bearing 308. A spring 309 is provided between the countersunk hole and the through hole ear 203. The threads of the threaded shaft 310 and the through hole ear 203 are engaged.

[0020] As a preferred technical solution of this utility model, such as Figures 1 to 5 As shown, one side of the support ring 501 is detachably connected to the retaining ring 6 by bolts. The retaining ring 6 is provided with a guide block 601. The other side of the support ring 501 is detachably connected to the fixing ring 7 by bolts. There are three gears 701 between the fixing ring 7 and the support ring 501, arranged in a circular array. The fixing ring 7 is slidably connected to the sliding ring 8 through the sliding groove 801. The sliding ring 8 is provided with a toothed ring 802, which meshes with the gears 701.

[0021] The working principle of this utility model is as follows: The transmission shaft 1 is inserted into the middle of the clamping mechanism 2. The slip ring 8 is rotated, and the toothed ring 802 on the slip ring 8 drives the gear 701 to rotate. The gear 701 drives the rack 201 to move in a straight line. The rotating mechanism 3 on the rack 201 clamps the transmission shaft 1 to achieve support transmission. When the roller 301 needs to be replaced, the threaded shaft 310 needs to be rotated to disengage the movable clamping block 304 from the roller 301. The spring 309 is used to apply a pushing force from the threaded shaft 310 to the roller 301 to prevent the threaded shaft 310 from loosening and causing the roller 301 to fall off. This achieves anti-loosening and enables quick disassembly and replacement.
