[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution:

[0023] A portable electrical inspection instrument includes a housing 1. A pair of lifting rods slidably connected to the housing 1 are provided. A housing 3 is fixedly connected to the top of each lifting rod 2. A locking assembly is provided on the housing 3. A pair of locking plates 4 are fixedly connected to the top of the housing 1. A pair of release assemblies are provided on the opposite sides of the pair of locking plates 4. A lifting plate 5 is fixedly connected to the bottom of each lifting rod 2. A buffer pad 6 and a pair of pins 7 are fixedly connected to the bottom of the lifting plate 5. A movable box 8 is provided inside the housing 1. A pair of insertion holes are provided on the top of the movable box 8. A placement block 9 is provided inside the movable box 8. A placement groove is provided on the placement block 9. The inspection instrument body 10 is provided on the placement block 9. A baffle 11 is fixedly connected to one side of the movable box 8. Slider blocks 20 are fixedly connected to both sides of the movable box 8. Sliding grooves are provided on the inner walls of both sides of the housing 1. The sliding grooves are adapted to the sliders 20. A pair of connecting blocks are fixedly connected to one side of the baffle 11. A handle 21 is rotatably connected between the pair of connecting blocks. The housing 1 is for inspection. The instrument body 10 provides robust external protection, effectively resisting collisions and squeezing to prevent damage to the instrument. The instrument body 10 is placed in the placement slot on the placement block 9, which is located inside the movable box 8. The baffle 11 can be pulled by the handle 21, which can drive the movable box 8 to move. The movable box 8 can slide along the sliding grooves on both sides of the inner wall of the box 1 via the slider 20, making it convenient to put the instrument body 10 in and out. When the movable box 8 is stored in the box 1, the locking component on the locking plate 4 is released to cancel the locking component on the housing 3, allowing the housing 3 to descend between a pair of locking plates 4 until the locking component locks again, fixing the housing 3 between the locking plates 4. The housing 3 drives the lifting plate 5 to descend via the lifting rod 2, so that the buffer pad 6 abuts against the instrument body 10 to prevent the instrument body 10 from shaking in the placement slot on the placement block 9. The pin 7 is inserted into the socket on the movable box 8 to firmly fix the movable box 8 inside the box 1.

[0024] The locking assembly includes a pair of support blocks 12, each of which is fixedly connected to the bottom of the housing 3. A limit rod 13 is slidably connected to each support block 12. A spring 14 is sleeved on the outer periphery of the limit rod 13. A limit ring 15 is fixedly connected to the limit rod 13. One end of the limit rod 13 passes through the housing 3 and is slidably connected to it. A pair of locking holes are provided on the locking plate 4. The spring 14 pushes the limit ring 15 to make one end of the limit rod 13 firmly inserted into the corresponding locking hole on the locking plate 4, so that the housing 3 is locked between the pair of locking plates 4. The release assembly can push the limit rod 13 out of the corresponding locking hole on the locking plate 4. When both limit rods 13 on the housing 3 are pushed out of the corresponding locking holes on the locking plate 4, the housing 3 is released. When the housing 3 drops to a suitable height, the spring 14 pushes the limit ring 15 to make one end of the limit rod 13 re-insert into the locking hole on the locking plate 4, and the housing 3 is fixed again.

[0025] The release assembly includes a cover 16, which is fixedly connected to one side of the locking plate 4. A slide rod 17 is slidably connected to the cover 16. A contact block 18 is fixedly connected to one end of the slide rod 17, and a pressing block 19 is fixedly connected to the other end of the slide rod 17. Pressing the pressing block 19 causes the slide rod 17 to slide on the cover 16, and the slide rod 17 pushes the limiting rod 13 through the contact block 18.

[0026] The working principle of this utility model is as follows:

[0027] The instrument body 10 is placed in the placement slot on the placement block 9. The placement block 9 is set in the movable box 8. The baffle 11 can be pulled by the handle 21. The baffle 11 can drive the movable box 8 to move. The movable box 8 can slide along the sliding groove on both sides of the inner wall of the box 1 by the slider 20, which makes it convenient to pick up and put down the instrument body 10.

[0028] When the movable box 8 is stored inside the housing 1, pressing the pressing block 19 causes the sliding rod 17 to slide on the cover 16. The sliding rod 17 pushes the limiting rod 13 through the contact block 18, pushing the limiting rod 13 out of the corresponding locking hole on the locking plate 4. When both limiting rods 13 on the housing 3 are pushed out of the corresponding locking holes on the locking plate 4, the housing 3 is released and can descend between the pair of locking plates 4. The housing 3 descends through the lifting rod 2, driving the lifting plate 5 to descend. When the housing 3 descends to a suitable height, the spring... 14 By pushing the limiting ring 15, one end of the limiting rod 13 is re-inserted into the locking hole on the locking plate 4, and the housing 3 is fixed again. At this time, the buffer pad 6 presses against the instrument body 10 to prevent the instrument body 10 from shaking in the placement slot on the placement block 9. The pin 7 is inserted into the insertion hole on the moving box 8 to firmly fix the moving box 8 in the box 1. The box 1 can be lifted through the housing 3 for easy carrying. The box 1 provides a sturdy external protection for the instrument body 10, which can effectively resist collisions and squeezing and avoid damage to the instrument.
