When the server moves backward until it contacts the wiring head 44, manually push the limiting frame 42 forward to drive the wiring head 44 to move forward and insert it into the socket of the server. In this way, when installing the server, the placement frame 32 can guide the server to facilitate the accurate insertion of the wiring head 44 into the socket of the server, and the limiting frame 42 can make the cables of the wiring head 44 tidy to prevent the cables from being too messy. When the server needs to be taken out, just pull the server forward out of the placement frame 32. Under the limiting action of the first slide bar 43 and the limiting frame 42, the wiring head 44 is automatically separated from the server. In this way, the disassembly and assembly efficiency of the server can be improved.

[0060] Example 2

[0061] On the basis of Example 1, Figure 2 and Figure 5-Figure 8As shown, it also includes a mounting mechanism 5 and a locking mechanism 6. The mounting mechanism 5 is used to automatically insert the wiring head 44 into the socket of the server. The locking mechanism 6 is used to limit the limit frame 42. The mounting mechanism 5 includes a first rack 51, a spur gear 52, a second rack 53, a fixing rod 54, a first linear spring 55, a second slide rod 56 and a second linear spring 57. The left sides of the two limit frames 42 are welded with a first rack 51, and the first rack 51 is used to drive the limit frame 42 to move. Two fixing rods 54 are welded on the left rear side of the middle part of the main frame 1. The two fixing rods 54 are distributed up and down. The two fixing rods 54 are rotatably connected with spur gears 52. The first rack 51 is meshed with the bottom of the spur gear 52. Two second sliding rods 56 are welded inside the left rear side of the main frame 1. The front sides of the two second sliding rods 56 are slidably connected with second racks 53. The second racks 53 are slidably connected to the main frame 1. The second racks 53 are meshed with the upper part of the spur gear 52. The rear of the four first sliding rods 43 are sleeved The first linear spring 55, the two ends of the first linear spring 55 are respectively connected to the rear side of the first slide bar 43 and the rear side of the limit frame 42, the two second slide bars 56 are respectively sleeved with a second linear spring 57, the two ends of the second linear spring 57 are respectively connected to the second rack 53 and the main frame 1; the locking mechanism 6 includes a limit frame 61, a limit rod 62, a third slide bar 63 and a third linear spring 64, the limit frame 61 is welded on the right side of the two limit frames 42, and two sets of third linear springs are welded on the right side of the main frame 1. The sliding rods 63, each group has two third sliding rods 63, the upper group of third sliding rods 63 is slidably connected to the limiting rod 62, and the lower group of third sliding rods 63 is slidably connected to the limiting rod 62, the limiting rod 62 is used to limit the limiting frame 61, the rear part of the limiting rod 62 is L-shaped, the limiting frame 61 moves forward and contacts with the limiting rod 62, and the upper parts of the four third sliding rods 63 are all covered with third linear springs 64, and the two ends of the third linear springs 64 are respectively connected to the limiting rod 62 and the main frame 1.The server is pushed backward manually. When the server moves backward until it contacts the second rack 53, the second rack 53 is driven to move backward. The second linear spring 57 is compressed. The second rack 53 drives the spur gear 52 to rotate, thereby driving the first rack 51 to move forward. The first rack 51 drives the limit frame 42 to move forward. The first linear spring 55 is stretched. The limit frame 42 drives the terminal head 44 to move forward, so that the terminal head 44 is automatically inserted into the socket of the server. In this way, the terminal head 44 can be automatically moved in the process of moving the server. The installation has high installation efficiency, so there is no need to manually push the limit frame 42 forward, reducing the trouble of operation. When the limit frame 42 moves forward, it drives the limit frame 61 to move forward. When the limit frame 61 moves forward to contact with the limit rod 62, it pushes the limit rod 62 to move upward, and the third linear spring 64 is compressed. When the limit frame 61 moves forward to cross the limit rod 62, the third linear spring 64 is reset, driving the limit rod 62 to move downward and reset, and the limit rod 62 limits the limit frame 61. In this way, the limit frame can be prevented from being displaced. 42 will move backward and reset under the reset action of the first linear spring 55, causing the terminal head 44 to be separated from the server, preventing the server from being ejected from the placement frame 32 due to the reset of the first linear spring 55 and the second linear spring 57, which has good practicality. When the limit frame 42 needs to move backward, the limit rod 62 is manually moved upward, and the third linear spring 64 is compressed, so that the limit rod 62 is separated from the limit frame 61. The limit frame 42 drives the limit frame 61 to move backward and reset under the reset action of the first linear spring 55, and then releases the limit rod. 62, the third linear spring 64 is reset, driving the limit rod 62 to move downward and reset, the second linear spring 57 is reset, driving the second rack 53 to move forward and reset, and at the same time the first linear spring 55 is reset, driving the first rack 51 to move backward and reset, thereby driving the spur gear 52 to reverse and reset, the first rack 51 drives the limit frame 42 to move backward, the limit frame 42 drives the terminal head 44 to move backward and reset, the second rack 53 pushes the server to move forward, so that the server and the terminal head 44 are automatically separated, and then the server can be taken away manually.

[0062] like Figure 2 , Fig. 9 and Fig.10As shown, it also includes an anti-winding mechanism 7, which is used to wind the cable. The anti-winding mechanism 7 includes a pressure plate 71, a winding rod 72, a support plate 73 and a fourth linear spring 74. The support plates 73 are welded to the right rear sides of the tops of the two mounting plates 41. The support plates 73 are used to wind the cables. The upper parts of the two support plates 73 are slidably connected with pressure plates 71, and the pressure plates 71 are used to press the cables. The bottoms of the two pressure plates 71 are connected to the inner bottoms of the adjacent support plates 73 with fourth linear springs 74. The winding rods 72 are welded to the front sides of the tops of the two mounting plates 41, and the winding rods 72 are located on the right side of the limit frame 42. The cables on the terminal head 44 are manually passed around the front side of the winding rod 72 and then wound around the support plate 73. As the number of cables on the support plate 73 increases, the pressure plate 71 moves upward, the fourth linear spring 74 is stretched, and the pressure plate 71 presses the cables to prevent them from becoming loose. In this way, the cables can be stored and further organized to avoid the cables from being piled up due to excessive numbers. Then, when the limit frame 42 drives the terminal head 44 to move forward, since the cables are wound around the front side of the winding rod 72, the cables will not be too short, which facilitates the insertion of the terminal head 44 into the socket of the server. When storage is not needed, the cables on the winding rod 72 are removed, the fourth linear spring 74 is reset, and the pressure plate 71 is driven to move downward and reset.

[0063] like Figure 1 , Figure 2 , Fig.11 and Fig.12 As shown, an anti-slip mechanism 8 is also included, and the anti-slip mechanism 8 is used to protect the server. The anti-slip mechanism 8 includes an anti-slip plate 81, a fixed column 82 and a torsion spring 83. Two fixed columns 82 are welded on the left and right sides of the front of the main frame 1, and the four fixed columns 82 are slidably connected with anti-slip plates 81. The anti-slip plates 81 are used to protect the server. The upper and lower sides of the four fixed columns 82 are covered with torsion springs 83, and the two ends of the torsion spring 83 are respectively connected to the fixed column 82 and the anti-slip plate 81. When placing the server into the placement frame 32, the anti-slip plate 81 is manually rotated outward, and the torsion spring 83 is deformed. After the server is placed in the placement frame 32, the anti-slip plate 81 is released, and the torsion spring 83 is reset, driving the anti-slip plate 81 to reverse and reset. The anti-slip plate 81 is used to limit the server. When the second rack 53 moves forward and resets under the reset of the second linear spring 57, it drives the server to move forward out of the placement frame 32. The anti-slip plate 81 buffers the server to prevent the server from being ejected from the placement frame 32 due to inertia. In this way, the server can be protected.

[0064] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
