After polishing, the lower ends of the three elastic telescopic rods are all arc-shaped structures, and the elastic telescopic rods are connected to the above-mentioned slots; the cleaning part is composed of a sliding seat, a sliding frame, a cleaning block, a mounting block, a tooth row, an auxiliary box, a through hole, an elastic part and a contact switch. There are two sliding seats in total, and the two sliding seats are symmetrically installed on the front end surface of the box; the fixed part is composed of a sliding rod, a force block, a support seat, a ground nail, a support plate and a sphere. There are four sliding rods in total, two of which are slidably connected to the left side of the box, and the other two sliding rods are slidably connected to the right side of the box.

[0006] Furthermore, a gear is installed on each of the rotating shafts, and the three gears are meshed with each other. During use, when one rotating shaft rotates, the three rotating shafts are in a synchronous rotation state.

[0007] Furthermore, a sliding frame is slidably connected to the two sliding seats, a cleaning block is adhered to the rear end surface of the sliding frame, and the cleaning block is in elastic contact with the glass on the front side of the box body.

[0008] Furthermore, an elastic member is connected to the box body, and a lower end of the elastic member is connected to the sliding frame.

[0009] Furthermore, a mounting block is fixed on the sliding frame, a tooth row is mounted on the mounting block, and the tooth row is meshed with the gear. When the sliding frame moves downward until the tooth row is meshed with the gear, the gear rotates 90 degrees.

[0010] Furthermore, an auxiliary box is fixed on the front end of the sliding frame. The auxiliary box is a rectangular box-shaped structure. A through hole is opened on the rear end of the auxiliary box. The through hole is aligned with the front glass of the box body. When the sliding frame slides downward, the through hole is in a jet state.

[0011] Furthermore, there is a contact switch on the front end surface of the box, which is connected to the circuit of the lamp tube. The contact switch is in elastic contact with the top end surface of the sliding frame. At this time, the circuit of the lamp tube is in an on state. Then, when the diagnostician pulls down the sliding frame to clean the glass on the front side of the box, the contact switch is disengaged from the squeezing of the sliding frame, and the lamp tube is in an off state.

[0012] Furthermore, a force block is welded on the inner side of the two sliding rods on the left and the two sliding rods on the right, and a support seat is welded on the outer side of the two sliding rods on the left and the two sliding rods on the right, and a ground nail is inserted on the support seat.

[0015] Beneficial Effects 1. The present application is provided with a diagnosis part and a cleaning part. On the one hand, since each of the rotating shafts is provided with a gear, the three gears are meshed with each other. During use, when one rotating shaft rotates, the three rotating shafts are in a synchronous rotation state. At this time, the three diagnostic icons can be adjusted synchronously, thereby improving the adjustment efficiency. Also, since a sliding frame is slidably connected to the two sliding seats, a cleaning block is adhered to the rear end surface of the sliding frame, and the cleaning block is in elastic contact with the glass on the front side of the box body, during use, when the sliding frame slides downward, the glass on the front side of the box body can be wiped and cleaned by the cleaning block. Also, since an elastic member is connected to the box body, and one end of the lower end of the elastic member is connected to the sliding frame, the sliding frame and the cleaning block can be automatically reset by the elastic member during use. Also, since a mounting block is fixed on the sliding frame, a tooth row is installed on the mounting block, and the tooth row is meshed with the gear, when the sliding frame moves downward until the tooth row is meshed with the gear, the gear rotates 90 degrees, and the 90-degree rotation adjustment of the diagnostic icon is achieved. Therefore, the automatic adjustment of the diagnostic icon can be achieved while the glass on the front side of the box body is wiped and cleaned. On the other hand, since an auxiliary box is fixed on the front end face of the sliding frame, the auxiliary box is a rectangular box-shaped structure, and a through hole is opened on the rear end face of the auxiliary box. The through hole is aligned with the front glass of the box body. When the sliding frame slides downward, the through hole is in a jet state. At this time, the airflow ejected from the through hole can achieve airflow cleaning of the front end glass of the box body.

[0016] 2. Through the fixed setting, since a force block is welded on the inner side of the two sliding rods on the left side and the two sliding rods on the right side, a support seat is welded on the outer side of the two sliding rods on the left side and the two sliding rods on the right side, and a ground nail is inserted on the support seat. During use, the two support seats can be pulled outward and then fixed by the ground nails, so that the device can be conveniently used outdoors; the support seat is a rectangular box-shaped structure, and sand can be placed in the support seat to achieve auxiliary fixation; and because a support plate is slidably connected to the bottom of the box body, a sphere is welded at one end above the support plate, the sphere and the two force blocks, and the contact position between the force block and the sphere is an inclined structure, and the two force blocks are arranged in a mirror shape. When the box body is placed on the ground, the two support plates can be synchronously unfolded through the support of the sphere, which improves convenience.

[0017] 3. Through the setting of the contact switch, since there is a contact switch on the front end surface of the box, the contact switch is connected to the circuit of the lamp tube, and the contact switch is in elastic contact with the top surface of the sliding frame. At this time, the circuit of the lamp tube is in an on state. Then, when the diagnostician pulls down the sliding frame to clean the glass on the front side of the box, the contact switch is disengaged from the squeezing of the sliding frame. At this time, the lamp tube is in an off state, which can prevent the diagnostician from observing the adjustment direction of the diagnostic icon, thereby affecting the diagnostic result.
