[0035] Example 1, please refer to Figure 1-Figure 3 , a transmission member fastening device comprises a first seat body 1 and a second seat body 2 located on one side of the first seat body 1, both sides of the second seat body 2 are fixedly connected to the limit plates 3, and the two limit plates 3 are provided with notches 4 on the sides away from each other. The first seat body 1 is connected to two connecting shafts 6 through bearings, and the two connecting shafts 6 pass through the two notches 4 respectively and are fixedly connected to a pressure plate 8, which contacts the top of the limit plate 3 to limit the limit plate 3. The present application realizes the fixation of the first seat body 1 and the second seat body 2 by the limit plate 3, notches 4, connecting shafts 6 and pressure plates 8 set, and the limit plate 3 is pressed by the pressure plate 8 to achieve the fixation of the first seat body 1 and the second seat body 2. When the position of the pressure plate 8 is rotated to correspond to the notch 4, the fixation of the second seat body 2 can be released, so that the disassembly and assembly between the first seat body 1 and the second seat body 2 is convenient, which is conducive to inspection and maintenance and improves work efficiency.

[0036] Furthermore, the size of the notch 4 is matched with the size of the pressing plate 8 , so that when the pressing plate 8 is rotated to a position corresponding to the notch 4 , the limiting effect of the pressing plate 8 on the limiting plate 3 can be released.

[0037] Further, such as Figure 2and Figure 3 As shown, limiting holes 16 are provided on both sides of the top of the first seat body 1, and a limiting rod 17 is inserted into the limiting hole 16. One end of the limiting rod 17 is fixedly connected to the second seat body 2. The limiting hole 16 and the limiting rod 17 cooperate with each other to limit the first seat body 1 and the second seat body 2, thereby improving the stability between the first seat body 1 and the second seat body 2.

[0038] Further, such as Figure 1 and Figure 4 As shown, two mounting holes 18 are provided on the first base body 1 , and the mounting holes 18 are used for mounting the first base body 1 . The first base body 1 can be mounted at a corresponding position by passing bolts through the mounting holes 18 .

[0039] Embodiment 2 further optimizes the transmission member fastening device provided in Embodiment 1. Specifically, Figure 1-Figure 3 As shown, a limiting groove 15 is provided on the side where the second seat body 2 and the first seat body 1 are close to each other, and a transmission member bearing 14 is placed between the two limiting grooves 15, and the transmission member bearing 14 is used to connect with the transmission member.

[0040] Further, such as Figure 4 As shown, a driving part is arranged in the first seat body 1 , and the driving part is connected to the two connecting shafts 6 . The driving part is used to drive the two connecting shafts 6 to rotate, so that the connecting shafts 6 can drive the pressing plate 8 to rotate.

[0041] Further, such as Figure 4 As shown, the driving part includes a chamber 5 opened in the first seat body 1, and two racks 9 are slidably connected in the chamber 5. The two racks 9 are meshed with gears 7. The two gears 7 are respectively fixed on the outer surfaces of two connecting shafts 6. During the movement of the rack 9, the connecting shaft 6 can be driven to rotate through the gear 7, thereby enabling the connecting shaft 6 to drive the pressure plate 8 to rotate.

[0042] Further, such as Figure 4 As shown, the two racks 9 are respectively located on the inner walls on both sides of the chamber 5, and a connecting rod 11 is fixedly connected between the two racks 9. A handle 10 is fixedly connected to one end of one of the racks 9, and the end of the handle 10 away from the rack 9 passes through the first seat body 1. When the handle 10 is pulled, the two racks 9 can be moved through the connecting rod 11.

[0043] Embodiment 3 further optimizes the transmission member fastening device provided in Embodiment 2. Specifically, Figure 4 As shown, a limiting seat 19 is sleeved on the outer surface of the rack 9 , and the limiting seat 19 is fixedly connected to the side wall of the chamber 5 .

The force of the spring 13 can limit the two racks 9 through the connecting rod 11 to reduce the situation where the two racks 9 move on their own.

[0045] The use process of the transmission member fastening device provided by the utility model is as follows:

[0046] The transmission member bearing 14 is used to connect with the transmission member, and the installation can be realized by installing the first seat body 1 to the corresponding position through bolts and mounting holes 18;

[0047] When the second seat body 2 and the first seat body 1 need to be separated, the handle 10 is pulled, and the handle 10 and the connecting rod 11 cooperate to drive the two racks 9 to move. During the movement of the racks 9, the connecting shaft 6 and the pressure plate 8 are driven to rotate through the gear 7, and the pressure plate 8 is rotated to separate from the limiting plate 3. The second seat body 2 is pulled so that the pressure plate 8 passes through the notch 4, and the limiting rod 17 is separated from the limiting hole 16, that is, the disassembly of the second seat body 2 and the first seat body 1 is realized, so as to realize the separation of the transmission member bearing 14 from the first seat body 1 and the second seat body 2;

[0048] During installation, pull the handle 10 outward, place the transmission bearing 14 in the limit groove 15, and then insert the limit rod 17 into the limit hole 16. When the limit plate 3 contacts the first seat body 1, release the handle 10. The force of the spring 13 drives the two racks 9 to reset through the connecting rod 11. At this time, the pressure plate 8 rotates to contact the limit plate 3 to achieve installation.
