[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1-4, A workbench for drilling electrical control experiments, including a work platform 1. Two connecting seats 4 are fixedly installed on the bottom side of the work platform 1. A frame 6 is arranged below the work platform 1. Two mounting blocks 9 are fixedly installed on the top side of the frame 6. A circular hole is formed in one mounting block 9, and a bidirectional screw 10 is arranged in the circular hole. One end of the bidirectional screw 10 is rotatably connected to one side of the other mounting block 9. The outer side of the bidirectional screw 10 is respectively slidably installed with a first slider 13 and a second slider 14. Linkage components are arranged between the first slider 13 and the second slider 14 and the two connecting seats 4. An adjusting and limiting component is arranged at the other end of the bidirectional screw 10. A test platform 2 is arranged on the top side of the work platform 1. The linkage component includes connecting columns 15 fixedly installed on both sides of the first slider 13 and the second slider 14. Linkage rods 16 are movably sleeved on multiple connecting columns 15. Multiple linkage rods 16 are grouped in pairs and are respectively movably sleeved in the two connecting seats 4. Connecting rods 17 are fixedly installed on the sides of the two groups of linkage rods 16 close to each other. The two groups of linkage rods 16 are symmetrically arranged. By clockwise rotating the rotating rod 12 to drive the turntable 11 to rotate, the bidirectional screw 10 is synchronously rotated clockwise, so that the first slider 13 and the second slider 14 move away from each other. When the first slider 13 and the second slider 14 move away from each other, the other ends of the two groups of linkage rods 16 will be jacked up towards the two connecting seats 4, so that the work platform 1 can be driven to move up. When the turntable 11 is rotated counterclockwise, the first slider 13 and the second slider 14 move closer to each other, so that the other ends of the two groups of linkage rods 16 move down, and then the work platform 1 will move down. By rotating the turntable 11 to drive the bidirectional screw 10 to rotate forward and backward, the rising and falling of the work platform 1 can also be realized, so that it is not necessary for personnel to keep bending down to operate the experimental equipment on the work platform 1.

[0022] Specifically, the adjustment and limit assembly includes a rotary disk 11 fixedly installed at the other end of the bidirectional screw 10. Two rotating rods 12 are fixedly installed on the outer side of the rotary disk 11, and the two rotating rods 12 are symmetrically arranged. One side of the frame 6 is fixedly installed with a side plate 18. The side plate 18 and the rotary disk 11 are respectively provided with a plurality of threaded grooves 20 and a plurality of threaded holes 19. One of the plurality of threaded holes 19 is internally threaded with a limit rod 21, and the other end of the limit rod 21 is threadedly installed into the threaded groove 20 aligned with one of the threaded holes 19. By rotating the rotary disk 11 clockwise or counterclockwise, the forward and reverse rotation of the bidirectional screw 10 can be realized, so that the first slider 13 and the second slider 14 move away from or close to each other, and thus the upward and downward movement of the working platform 1 is realized. And through the arranged limit rod 21, after the height is adjusted to a suitable position, by threadedly installing the other end of the limit rod 21 into one of the threaded holes 19, and then continuously rotating the limit rod 21, the other end of the limit rod 21 can be threadedly installed into the threaded groove 20 aligned with the threaded hole 19, so as to realize the fixed connection between the rotary disk 11 and the side plate 18, avoiding that knocking the rotary disk 11 will cause the bidirectional screw 10 to rotate, so that the working platform 1 moves downward, resulting in the equipment placed on the working platform 1 may fall off.

[0023] Specifically, the inner walls of the mutually close sides of the frame 6 are fixedly installed with the same connecting plate 7. A fixed block 8 is fixedly installed on the top side of the connecting plate 7. The fixed block 8 is provided with a circular hole, and the bidirectional screw 10 is movably arranged in the circular hole opened in the fixed block 8. A plurality of support legs 5 are arranged below the working platform 1, and the frame 6 is fixedly installed between the plurality of support legs 5. The top sides of the plurality of support legs 5 are respectively provided with guide grooves, and the plurality of guide grooves are respectively adapted to the plurality of guide rods 3. The plurality of guide rods 3 are respectively movably inserted into the plurality of guide grooves. By arranging the plurality of guide rods 3, when the working platform 1 moves up and down, the plurality of guide rods 3 always move in the guide grooves opened in the plurality of support legs 5, which can play a guiding role in the upward and downward movement and effectively avoid the situation of deviation.

[0024] During use: When it is necessary to adjust the height of the working platform 1, rotate the rotating rod 12 clockwise to drive the rotating disc 11 to rotate, so that the bidirectional screw rod 10 rotates synchronously clockwise, and then the first slider 13 and the second slider 14 move away from each other. When the first slider 13 and the second slider 14 move away from each other, the other ends of the two linkage rods 16 will be jacked up towards the two connecting seats 4, so that the working platform 1 can be driven to move upward. When it moves to the appropriate height, stop rotating the rotating disc 11. Thread the other end of the limiting rod 21 into one of the threaded holes 19, and then continue to rotate the limiting rod 21 to thread the other end of the limiting rod 21 into the threaded groove 20 aligned with the threaded hole 19, so as to realize the fixed connection between the rotating disc 11 and the side plate 18, and avoid knocking the rotating disc 11 to cause the bidirectional screw rod 10 to rotate, so that the working platform 1 moves downward, resulting in the equipment placed on the working platform 1 may fall. By rotating the rotating disc 11 to drive the bidirectional screw rod 10 to rotate forward and backward, the rising and falling of the working platform 1 can also be realized, so that it is not necessary for personnel to keep bending down to operate the experimental equipment on the working platform 1.
