[0037] like Figure 3 As shown, the baffle plate 2 includes a first horizontal plate 202, and a baffle plate hole 201 is arranged on the first horizontal plate 202; one end of the first horizontal plate 202 is fixedly connected to the first vertical plate 203. The baffle plate 2 cooperates with the bayonet 3 to play a protective role. The baffle plate hole 201 is arranged on the baffle plate 2, and the baffle plate hole 201 is a round hole. The third connecting member 304 of the bayonet 3 is inserted into the baffle plate hole 201, thereby preventing the pull plate 1 from moving, so that the pull plate 1 limits the position of the wire rack shaft 8, and prevents the wire rack shaft 8 from falling out.

[0038] One end of the first positioning hole 101 is a round hole, and the other end of the first positioning hole 101 is an oblong hole. The round hole and the oblong hole are connected to form the first positioning hole 101. When the safety pin 4 is located in the round hole, the safety pin 4 is in a pop-up state, and the pull plate 1 is stuck. The safety pin 4 can slide in the oblong hole. When the safety pin 4 is in the oblong hole, the safety pin 4 is in a pressed state, and the pull plate 1 can be positioned.

[0039] like Figure 5 As shown, the bayonet 3 includes a first connecting member 301, and a first mounting hole 302 is provided on the first connecting member 301; one end of the first connecting member 301 is connected to the second connecting member 303.

The first connecting member 301 is connected to the wire rack 10 through the first mounting hole 302, and the connection method is a movable connection, so that the bayonet 3 rotates around the position of the first mounting hole 302, so that the third connecting member 304 is inserted or pulled out, and the pull plate 1 is installed or removed.

[0041] like Figure 7 As shown, the upper and lower ends of the first pressing plate 5 are provided with second mounting holes 501, the middle of the first pressing plate 5 is provided with an arc-shaped opening 502, and the first pressing plate 5 is located on one side of the wire rack shaft 8. Figure 8 As shown, the third mounting holes 601 are provided at the upper and lower ends of the second pressing plate 6, and the second pressing plate 6 is located on the other side of the wire rack shaft 8. The first pressing plate 5 and the second pressing plate 6 cooperate to press the pull plate 1 tightly to prevent the pull plate 1 from coming out. The arc-shaped opening 502 of the first pressing plate 5 is for easy installation to prevent the rotation of the wire rack shaft 8 from being affected.

[0042] like Figure 1 As shown, a second positioning hole 11 is provided at one end of the wire rack 10, and the first positioning hole 101 is aligned with the second positioning hole 11. The safety pin 4 passes through the first positioning hole 101 and the second positioning hole 11 in sequence, and a safety pin spring 7 is provided at the end of the safety pin 4. The safety pin 4, the first positioning hole 101 and the second positioning hole 11 cooperate to connect one end of the pull plate 1 to the wire rack 10. When in use, the safety pin 4 can be pressed to make the safety pin 4 pop out, and then the pull plate 1 is slid to remove the pull plate 1.

[0043] Mounting posts 12 are provided at the upper and lower ends of the wire rack 10, and the pull plate 1 is provided between the upper and lower mounting posts 12. Two mounting posts 12 are provided at the upper and lower ends of the side of the wire rack 10, respectively, and the second mounting hole 501 of the first pressing plate 5 and the third mounting hole 601 of the second pressing plate 6 cooperate with the mounting posts 12 to install the first pressing plate 5 and the second pressing plate 6 in front of the pull plate 1, and closely adhere to the pull plate 1, thereby preventing the pull plate 1 from moving.

[0044] Embodiment 2:

[0045] like Fig. 9 As shown, the pull plate 1 is in the protection state, at this time, the third connecting member 304 of the bayonet 3 is in the baffle hole 201 of the baffle 2, and the bayonet 3 is closed; Fig.11 As shown, the safety pin 4 is in the circular hole of the first positioning hole 101 and the second positioning hole 11, and the safety pin 4 pops out to clamp the pull plate 1. The pull plate 1 is limited by the pull plate 1, the baffle 2, the locking pin 3 and the safety pin 4, so that double protection is achieved.

[0046] like Fig.10As shown, the third connecting member 304 of the bayonet 3 is pulled out from the baffle hole 201 of the baffle 2, and the bayonet 3 is opened; Fig.12 As shown, the end of the safety pin 4 is out of the second positioning hole 11 and is only in the first positioning hole 101 , and the safety pin 4 presses down the tension plate 1 to position it.

[0047] When the equipment is running, the wire rack shaft 8 rotates with the I-shaped wheel 9. During the rotation, the pull plate 1 will move forward and backward, causing the wire rack shaft 8 to fall out. A baffle 2 is added to the front end of the pull plate 1, and a first positioning hole 101 is drilled at the rear end. When the wire rack shaft 8 needs to be removed, the safety pin 4 is pressed toward the wire rack 10, and the safety pin 4 is ejected by the safety pin spring 7 installed at the bottom, so that the first positioning hole 101 at the rear of the pull plate 1 slides over the safety pin 4. When the pull plate 1 slides, the first latch 3 needs to be opened first, so that the latch 3 first falls out of the baffle hole 201 at the front end of the pull plate 1, and then the pull plate 1 can be pulled out of the wire rack shaft 8.

[0048] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
