DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: an automated test bench applied to electrical engineering, including a base 1. A storage cabinet penetrates and is slidably connected to the front surface of the base 1. An operating table 2 is arranged on the upper surface of the base 1. A variety of electrical components are arranged on the front surface of the operating table 2. The base 1 and the operating table 2 together form the test bench for experiments in the field of electrical engineering. An adjusting component is arranged on the upper surface of the operating table 2. The adjusting component can sweep the experimental impurities remaining on the upper surface of the operating table 2 and can facilitate the laying of drawings flat on the operating table 2. A supporting component is arranged on the rear surface of the base 1. The supporting component can provide support for the device when the device is stationary. Universal wheels 6 are arranged on the lower surface of the base 1. There are four groups of universal wheels 6, and the four groups of universal wheels 6 are evenly distributed at the four corners of the lower surface of the base 1. The universal wheels 6 are prior art and can be realized by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The universal wheels 6 have self-locking properties. A drawer 3 penetrates and slides on the front surface of the base 1. A handle is arranged on the front surface of the drawer 3. A letter lock is arranged on the front surface of the drawer 3. The letter lock is prior art and can be realized by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The letter lock is divided into two parts, one part is fixed on the front surface of the drawer 3, and the other part is fixed on the front surface of the base 1. The two parts can be locked to each other. A through square groove is opened at the left end of the upper surface of the base 1. The square groove is located above the drawer 3. A sliding groove 201 is opened at the front end of the upper surface of the operating table 2. The sliding groove 201 is horizontally opened. A through groove 202 is opened at the left end of the upper surface of the operating table 2. The impurities generated during the experiment can pass through the through groove 202.
[0033] Refer to Figure 1 , Figure 4 , Figure 5 , the adjusting component includes a moving block 41. A slider 42 is slidably connected to the inner wall of the moving block 41. The slider 42 slides longitudinally. A rotating shaft 43 penetrates and is rotatably connected to the front surface of the slider 42. A handwheel 44 is fixedly connected to the front surface of the rotating shaft 43. The handwheel 44 is convenient to grip. Rotating the handwheel 44 can drive the rotating shaft 43 to rotate. The adjusting component further includes a connecting plate 45. A rubber strip 46 is fixedly connected to the upper surface of the connecting plate 45. The rubber strip 46 is made of rubber. When the upper surface of the connecting plate 45 faces downwards, the rubber strip 46 will contact the upper surface of the operating table 2. A roller 47 is rotatably connected to the inner wall of the front side of the connecting plate 45. The roller 47 can rotate. When the drawing is laid on the operating table 2, the roller 47 rolls over the drawing from above, and can press out the wrinkles and air bubbles in the drawing. A clamping block 48 is elastically connected to the inner wall of the rotating shaft 43 through a compression spring 49. A clamping groove 401 is opened on the inner wall of the right side of the slider 42. The clamping block 48 and the clamping groove 401 fit together.
[0034] Refer to Figure 1 - Figure 3, the support assembly includes a support plate 51. The upper surface of the support plate 51 is penetrated and rotatably connected with a threaded rod 53. The support plate 51 provides support for the threaded rod 53. The upper surface of the threaded rod 53 is fixedly connected with a turntable 52. The turntable 52 facilitates rotation. The turntable 52 and the threaded rod 53 are concentric. Rotating the turntable 52 can drive the threaded rod 53 to rotate. The rear surface of the base 1 is penetrated and slidably connected with a connecting block 54. The connecting block 54 slides longitudinally. The inner wall of the base 1 is slidably connected with a return plate 55. The lower surface of the return plate 55 is fixedly connected with support legs 56. There are multiple groups of support legs 56, which are evenly distributed at the four corners of the lower surface of the return plate 55.
[0035] Refer to Figure 1 , Figure 4 , Figure 5 , the moving block 41 is slidably connected to the inner wall of the chute 201. The lower surface of the moving block 41 is provided with a protrusion, and the protrusion slides on the inner wall of the chute 201. The handwheel 44 penetrates the front surface of the moving block 41, and the handwheel 44 can move longitudinally. The upper surface of the operating table 2 is arranged in a concave shape. This concave setting can effectively prevent the experimental parts from falling during the experiment. The through groove 202 is located directly above the penetrated square groove and on the concave part. The lower surface of the roller 47 protrudes from the lower surface of the connecting plate 45. When the roller 47 faces downward, there is a certain gap between it and the operating table 2. If a drawing is laid on the operating table 2, when the roller 47 rolls over, it can flatten the drawing. The right surface of the clamping block 48 is arranged as an arc surface. Squeezing the arc surface of the clamping block 48, the clamping block 48 will move leftward and retract into the rotating shaft 43. The clamping block 48 is inserted into the inner wall of the card slot 401, which can limit the rotating shaft 43. There are two groups of card slots 401, and the two groups of card slots 401 are symmetrically distributed left and right with the center line of the slider 42 as the axis. The clamping block 48 can be inserted into another card slot 401 every 180 degrees of rotation. The clamping block 48 penetrates and is slidably connected to the right surface of the rotating shaft 43. One end of the compression spring 49 is fixedly connected to the left surface of the clamping block 48, and the other end of the compression spring 49 is fixedly connected to the inner wall on the left side of the rotating shaft 43. When the clamping block 48 moves leftward, it will squeeze the compression spring 49 to generate a reaction force. Without the influence of a large external force, the clamping block 48 cannot be pressed.
[0036] Refer to Figure 1 - Figure 3, the front surface of the support plate 51 is fixedly connected to the rear surface of the base 1. The threaded rod 53 passes through and is threadedly connected to the upper surface of the connecting block 54. The threaded rod 53 is prior art and can be implemented by those skilled in the art. Since it is prior art, it will not be described in detail in this case. The threaded rod 53 has self-locking property. The support leg 56 passes through and is slidably connected to the lower surface of the base 1, sliding longitudinally. When the support leg 56 moves to the lowest point, it can lift the universal wheel 6, so that the device can be stably supported. The front surface of the connecting block 54 is fixedly connected to the rear surface of the U-shaped plate 55, and the connecting block 54 and the U-shaped plate 55 will move synchronously.
[0037] Working principle: When this device is in use, if it is necessary to lay the drawing flat, first unfold the drawing and place it flat on the operating table 2, and pass one end under the roller 47. Then hold one end of the drawing and move it horizontally to drive the roller 47 to move horizontally. The horizontally moving roller 47 will press out the gas at the raised part of the drawing and flatten the wrinkled part of the drawing to ensure that the drawing is flat, which is convenient for people to view and use.
[0038] If it is necessary to clean the impurities on the operating table 2, grasp the handwheel 44 and rotate it to drive the rotating shaft 43 and the connecting plate 45 to rotate. When the rotating shaft 43 rotates, it will drive the clamping block 48 to move. When the clamping block 48 moves, its arc surface will be squeezed. Under the influence of external force, the clamping block 48 will retract into the rotating shaft 43 and disengage from the clamping groove 401 to release the limit on the rotating shaft 43, and will squeeze the compression spring 49 to generate a reaction force. When the clamping block 48 rotates 180 degrees, it will align with another clamping groove 401. Under the pushing force of the reaction force of the compression spring 49, the clamping block 48 will be inserted into another clamping groove 401 to limit the rotating shaft 43. At this time, the rubber strip 46 faces downward and will contact the upper surface of the operating table 2. Then move the handwheel 44 upward to drive the slider 42, the rotating shaft 43, the connecting plate 45 and the rubber strip 46 to move upward. The rubber strip 46 will disengage from the upper surface of the operating table 2. Then move the moving block 41 to the rightmost side of the operating table 2, and then release the handwheel 44 so that the lower surface of the rubber strip 46 contacts the upper surface of the operating table 2. Then move the moving block 41 to the left. The moving block 41 moving to the left will drive the rubber strip 46 to move to the left, further sweeping the impurities on the operating table 2 into the through groove 202. The impurities will enter the drawer 3 through the through groove 202 and the penetrating square groove, which is convenient for subsequent cleaning. When cleaning, unlock the letter lock and pull out the drawer 3, and then clean it.
[0039] When the device needs to be moved, grasp the turntable 52 and rotate it in the reverse direction. The turntable 52 will drive the threaded rod 53 to rotate in the reverse direction. The reversely rotating threaded rod 53 will drive the connecting block 54, the U-shaped plate 55 and the support leg 56 to move upward. The upward moving support leg 56 will disengage from the ground, and the universal wheel 6 will come into contact with the ground. At this time, unlocking the universal wheel 6 can facilitate the movement of the device. When the device is moved to a suitable location, lock the universal wheel 6 and then rotate the turntable 52 to drive the threaded rod 53 to rotate. The threaded rod 53 will drive the connecting block 54, the U-shaped plate 55 and the support leg 56 to move downward. When the support leg 56 moves to the lowest point, it will lift the universal wheel 6 to maintain the contact area between the device and the ground and ensure the stability of the device.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
