[0024] A rotating shaft 3 is arranged on the left and right sides of the storage groove 9, the rotating shaft 3 is rotatably connected with the test instrument shell 1, the upper end of the U-shaped supporting rod 2 is fixedly connected with the rotating shaft 3, the baffle 5 is fixedly connected with the outer edge of the rotating shaft 3, the non-return seats 4 for limiting the rotation of the baffle 5 are arranged on the front and rear sides of the test instrument shell 1, the non-return seats 4 are detachably connected with the test instrument shell 1, and the first positioning member for limiting the rotation of the baffle 5 is arranged on the non-return seat 4;

[0025] When the two U-shaped supporting rods 2 are opened, the rotating shaft 3 will rotate together with the baffle 5, when the U-shaped supporting rods 2 are completely opened, the baffle 5 on the rotating shaft 3 will contact the non-return seats 4 on the front and rear sides of the test instrument shell 1, the non-return seats 4 limit the rotation of the baffle 5, so that the two U-shaped supporting rods 2 are in a stable supporting state, and in the supporting process, the first positioning member on the non-return seat 4 further limits the rotation of the baffle 5, so that the baffle 5 will not be retracted due to external impact after being opened, and the use safety of the test instrument is improved.

[0026] A clamping seat 7 is arranged between the two rotating shafts 3, and the clamping seat 7 is fixedly connected to the center of the receiving groove 9. A clamping groove 8 is arranged at the lower end surface of the clamping seat 7 and is clamped with the lower end of the U-shaped supporting rod 2. The clamping groove 8 is internally provided with a second positioning member for preventing the U-shaped supporting rod 2 from loosening.

[0027] The two U-shaped supporting rods 2 are received in the receiving groove 9, so as to facilitate carrying of the tester. When the U-shaped supporting rod 2 is completely received in the receiving groove 9, the U-shaped supporting rod 2 is clamped in the clamping groove 8 arranged at the lower end of the clamping seat 7. The clamping groove 8 limits the U-shaped supporting rod 2, so as to avoid re-expanding of the U-shaped supporting rod 2. The second positioning member in the clamping groove 8 further limits loosening of the U-shaped supporting rod 2, thereby improving the storage stability of the U-shaped supporting rod 2.

[0028] The first positioning member is used for preventing the baffle 5 from rotating, thereby improving the supporting stability of the U-shaped supporting rod 2. Specifically, the first positioning member comprises a positioning bolt 11, the positioning bolt 11 penetrates the check seat 4, the positioning bolt 11 is threadedly connected with the check seat 4, and the positioning bolt 11 is threadedly connected with a positioning hole 12 arranged on the outer side of the baffle 5. When the U-shaped supporting rod 2 is completely expanded, the check seat 4 is tightly attached to the baffle 5, the positioning hole 12 is coincident with the axis of the positioning bolt 11, the positioning bolt 11 on the check seat 4 is screwed into the positioning hole 12, and the locking between the check seat 4 and the baffle 5 is completed, thereby improving the supporting safety of the U-shaped supporting rod 2.

[0029] The second positioning member is used for preventing the U-shaped supporting rod 2 from loosening in the clamping groove 8, thereby affecting the carrying of the tester. Specifically, the second positioning member comprises spherical pins 14 arranged on the left and right sides of the U-shaped supporting rod 2. The spherical pins 14 are attached to the lower end surface of the U-shaped supporting rod 2. The end of the spherical pin 14 away from the U-shaped supporting rod 2 is arranged in a pin groove 13 arranged on the inner side of the clamping groove 8. The spherical pin 14 is slidingly connected with the pin groove 13, and the spherical pin 14 is fixedly connected with a spring 15 arranged in the pin groove 13.

[0030] After the U-shaped supporting rod 2 is pushed into the clamping groove 8, the spherical pin 14 is compressed into the pin groove 13 under the extrusion of the U-shaped supporting rod 2. When the U-shaped supporting rod 2 is completely clamped in the clamping groove 8, the spherical pin 14 is pushed out of the pin groove 13 under the pushing of the spring 15, thereby limiting the U-shaped supporting rod 2 from the lower side of the U-shaped supporting rod 2. The U-shaped supporting rod 2 is secondarily limited without affecting the removal of the U-shaped supporting rod 2.

[0031] In addition, the lower end of the tester shell 1 is provided with a plurality of supporting legs 10, and the supporting legs 10 are fixedly connected to each corner of the lower end surface of the tester shell 1. The supporting legs 10 are used for preliminary supporting of the horizontally placed tester. The bottom of the supporting leg 10 is provided with an antiskid pad. The antiskid pad is made of rubber material and is designed with a plurality of dot-shaped protrusions.

[0032] The check seat 4 is a consumable part. In the preferred embodiment, the upper and lower ends of the check seat 4 are provided with fixing pins which pass through the check seat 4 and are screwed into the pin holes provided on the outer side of the tester shell 1. When the check seat 4 is removed from the tester shell 1, the fixing pins at the upper and lower ends of the check seat 4 are unscrewed from the pin holes on the outer side of the tester shell 1.

[0033] The clamping seat 7 is also a consumable part. In the preferred embodiment, the left and right ends of the clamping seat 7 are fixedly connected with pin plates 16 which are provided with mounting pins 17 which pass through the clamping seat 7 and are screwed into the pin holes provided on the inner side of the storage groove 9. Similarly, the clamping seat 7 is also connected with the tester shell 1 at the lower end by means of pins. When the clamping seat 7 is removed from the storage groove 9, the mounting pins 17 are unscrewed from the corresponding pin holes.

[0034] In order to improve the anti-slip ability of the U-shaped supporting rod 2, in the preferred embodiment, the lower end of the U-shaped supporting rod 2 is provided with a rubber cylinder 6 which is sleeved on the outer side of the U-shaped supporting rod 2 and is fixedly connected with the U-shaped supporting rod 2. The rubber cylinder 6 is arranged staggered with the clamping seat 7, and the outer side wall of the rubber cylinder 6 is also provided with a plurality of dot-shaped protrusions to further increase the friction between the rubber cylinder 6 and the desktop or the ground.

[0035] Working principle of the present application:

[0036] When the two U-shaped supporting rods 2 are opened, the shaft 3 will rotate together with the baffle 5. When the U-shaped supporting rods 2 are completely opened, the baffle 5 on the shaft 3 will contact the check seats 4 on the front and rear sides of the tester shell 1. The check seats 4 limit the rotation of the baffle 5 to ensure that the two U-shaped supporting rods 2 are in a stable supporting state. During the supporting process, the first positioning member on the check seat 4 further limits the rotation of the baffle 5 to ensure that the baffle 5 does not retract after being opened due to external impact, thereby improving the safety of the tester. The two U-shaped supporting rods 2 are stored in the storage groove 9 to facilitate the carrying of the tester. When the U-shaped supporting rods 2 are completely stored in the storage groove 9, the U-shaped supporting rods 2 are clamped into the clamping grooves 8 provided at the lower end of the clamping seat 7. The clamping grooves 8 limit the U-shaped supporting rods 2 to avoid re-expansion of the U-shaped supporting rods 2. The second positioning member in the clamping groove 8 further limits the loosening of the U-shaped supporting rods 2 to improve the stability of the storage of the U-shaped supporting rods 2.
