[0004] In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. In the above case, elastic ropes are vertically arranged on both sides of the horizontal plate to protect the fragile objects on the horizontal plate. However, during the use process, the sizes of the fragile objects are different, and the elastic ropes lack corresponding adjustment mechanisms, resulting in the elastic ropes being far away from the fragile objects and unable to effectively limit and protect the fragile objects. The fragile objects are easy to shake and collide with each other and be damaged during the transfer process. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0006] To achieve the purpose of the present utility model, the technical solution adopted by the present utility model is as follows: Design a forklift fork for handling fragile objects, including a fork plate. One end of the fork plate is vertically installed with a vertical plate. Elastic ropes are arranged on both sides of the fork plate. Two groups of adjusting bars are horizontally arranged above the fork plate; Adjusting mechanism: used for adjusting the use position of the elastic ropes. The adjusting mechanism includes a lead screw. Horizontally symmetric connection grooves are opened above the side of the vertical plate close to the fork plate. A connection block is slidably connected inside the connection groove. A threaded groove is horizontally penetrated through the front side of the connection block. The lead screw is threadedly connected with the threaded groove. One ends of the two connection blocks outside the connection groove are respectively fixedly connected with one ends of the two groups of adjusting bars; Disassembly and assembly mechanism: used for disassembly and assembly of the elastic ropes. The disassembly and assembly mechanism includes bolts. Connection sleeves are symmetrically installed at both ends of the elastic ropes. First fixing holes are opened on the outer sides of the adjusting bars. Second fixing holes are symmetrically opened on the front and back sides of the fork plate. The connection sleeve at the bottom end of the elastic rope is fixedly connected with the fork plate through a bolt penetrating the second fixing hole. The connection sleeve at the top end of the elastic rope is fixedly connected with the adjusting bar through a bolt penetrating the first fixing hole.

[0007] Preferably, a servo motor is fixedly connected to the upper end of the front side of the vertical plate. The shaft end of the servo motor is fixedly connected with one end of the lead screw.

[0008] Preferably, the thread directions on the front and back sides of the lead screw are opposite. The lead screw is rotationally connected with the inner wall of the connection groove through a bearing.

[0009] Preferably, the bolt is movably connected with the connection sleeve. The connection sleeve and the bolt are matched in size.

[0010] Preferably, the first fixing holes and the second fixing holes are respectively evenly opened on the outer sides of the adjusting bars and the fork plate, and the first fixing holes and the second fixing holes correspond to each other one by one.

[0011] Preferably, the adjusting bars and the fork plate are matched in size. The elastic ropes and the vertical plate are matched in size.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By controlling the servo motor to work, the present utility model can drive the lead screw to rotate. Through the threaded connection between the lead screw and the threaded groove inside the connection block, during the rotation of the lead screw, the two connection blocks can be driven to move relatively in the connection groove, further driving the two groups of adjusting bars to move relatively above the fork plate. Since the two ends of the elastic rope are respectively fixedly connected to the outer sides of the fork plate and the adjusting bar, during the movement of the adjusting bar, the top end of the elastic rope can be driven to move, so as to limit and protect the fragile objects above the fork plate, thus solving the problem that the existing forklift forks lack corresponding limit protection devices and the fragile objects are prone to shaking and colliding with each other and being damaged during the transfer process.

[0014] 2. The utility model is movably connected to the connecting sleeve through bolts. The bolts are threadedly connected to the second fixing holes of the fork plate and the first fixing holes of the adjusting strip, which facilitates the fixed connection between the connecting sleeve, the adjusting strip and the fork plate, further facilitates the replacement of the elastic rope, and avoids the wear of the elastic rope, thus affecting the use effect.

[0021] After the forklift pushes the fork board 1 to lift the fragile object, the servo motor 17 is controlled to work through the corresponding controller, which can drive the lead screw 16 to rotate. Since the lead screw 16 is in threaded connection with the threaded groove 15 inside the connecting block 14, and the thread directions on both sides of the lead screw 16 are opposite, during the rotation of the lead screw 16, it can drive the two groups of connecting blocks 14 to move relatively in the connecting groove 13, further driving the two groups of adjusting bars 18 to move relatively above the fork board 1. Since the two ends of the elastic rope 12 are respectively fixedly connected to the outside of the fork board 1 and the adjusting bar 18, during the movement of the adjusting bar 18, it can drive the top end of the elastic rope 12 to move, making the elastic rope 12 fit the fragile object above the fork board 1, thereby limiting and protecting the fragile object above the fork board 1, and further solving the problem that the existing forklift forks lack corresponding limiting and protecting devices, and the fragile objects are prone to shaking and colliding with each other and being damaged during the transfer process.

[0022] Specifically, refer to Figures 1 to 3 , the disassembly and assembly mechanism: used for the disassembly and assembly of the elastic rope 12. The disassembly and assembly mechanism includes a bolt 21. Connecting sleeves 2 are symmetrically installed at both ends of the elastic rope 12.

The first fixing holes 22 and the second fixing holes 23 are respectively evenly opened on the outside of the adjusting bar 18 and the fork board 1, and the first fixing holes 22 and the second fixing holes 23 correspond to each other one by one.

[0023] Pass the bolt 21 through the connecting sleeves 2 at both ends of the elastic rope 12 and thread it with the second fixing hole 23 on the outside of the fork board 1 and the first fixing hole 22 of the adjusting bar 18, which is convenient for the connecting sleeve 2 to be fixedly connected to the adjusting bar 18 and the fork board 1, further realizing the installation of the elastic rope 12. On the contrary, unscrew the bolt 21 to disassemble the connecting sleeve 2, which is convenient for replacing the elastic rope 12 and avoiding the wear of the elastic rope 12 and affecting the use effect.
