By setting the clamping device 4, the effect of clamping the equipment placed on the test machine body 1 is achieved, and it is avoided that when the staff needs to use the test machine body 1 to test the equipment, the test machine body 1 is hit by the outside world, resulting in the equipment on the test machine body 1 being offset, thereby causing the test machine body 1 to test the equipment. The data is wrong, thereby improving the practicality of the device. A dustproof device 5 is provided on the side of the test machine body 1 close to the control button 3. By setting the dustproof device 5, the effect of dustproofing the idle control button 3 is achieved, and it is avoided that when the test machine body 1 is restricted for a long time, dust falls on the surface of the control button 3, causing dust to enter the gap of the control button 3, thereby causing the control button 3 to fail, thereby improving the protection of the device.

[0030] The specific arrangement and function of the clamping device 4 and the dustproof device 5 will be described in detail below.

[0031] Reference Figure 2 and Figure 3As shown, in this embodiment: the clamping device 4 includes two clamping plates 43, the two clamping plates 43 are slidably connected to the surface of the test machine body 1, the two clamping plates 43 are fixedly connected to the connecting block 42 on the side away from each other, the connecting block 42 is rotatably connected to the driving rod 41 on the side away from the clamping plate 43, the arc surface of the driving rod 41 is threadedly connected to the test frame 2, the end of the driving rod 41 away from the connecting block 42 is fixedly connected to the handle 44, the side of the clamping plate 43 away from the connecting block 42 is slidably connected to the cushion 45, the cushion 45 Two fixing plates 46 are fixedly connected to one side close to the clamping plate 43, and the surface of the fixing plate 46 is slidably connected to the clamping plate 43. When the staff turns the handle 44, the handle 44 drives the driving rod 41 to move in the internal thread of the test frame 2, and at the same time, the driving rod 41 drives the connecting block 42 to move, the connecting block 42 drives the clamping plate 43 to move, and the clamping plate 43 drives the soft pad 45 to move until the soft pad 45 abuts against the equipment placed on the test machine body 1. At this time, the soft pad 45 achieves the purpose of preventing the equipment placed on the test machine body 1 from being damaged. The clamping plate 43 is provided with two sliding grooves 47 on one side close to the connecting block 42. The inner surface of the sliding groove 47 is slidably connected with an insert plate 48. The surface of the insert plate 48 is slidably connected with the fixing plate 46. When the staff inserts the fixing plate 46 into the clamping plate 43, the insert plate 48 is pushed. The insert plate 48 slides in the sliding groove 47 until the insert plate 48 is inserted into the fixing plate 46. At this time, the fixing plate 46 is restricted, and the cushion 45 is prevented from being separated from the clamping plate 43 due to external shaking. A positioning rod 49 is fixedly connected to one side of the connecting block 42 close to the driving rod 41, and the arc surface of the positioning rod 49 is slidably connected to the test frame 2. When the staff turns the handle 44, the handle 44 drives the driving rod 41 to move in the internal thread of the test frame 2. At the same time, the driving rod 41 drives the connecting block 42 to move, and the connecting block 42 drives the positioning rod 49 to slide in the test frame 2. At this time, the positioning rod 49 has the effect of limiting the connection block 42 from rotating with the driving rod 41, so as to improve the stability of the clamping plate 43 in clamping the equipment to be tested.

[0032] Reference Figure 4 and Figure 5As shown, specifically, the dustproof device 5 includes a dustproof frame 51, which is fixedly connected to the side of the test machine body 1 close to the control button 3, a dustproof plate 52 is slidably inserted in the dustproof frame 51, one side of the test machine body 1 is fixedly connected to the support plate 53, a fixing rod 54 is fixedly connected to the surface of the support plate 53, an operating panel 55 is slidably connected to the circular arc surface of the fixing rod 54, a plug rod 56 is fixedly connected to the side of the operating panel 55 close to the support plate 53, a plug hole is provided on the surface of the dustproof plate 52, one end of the fixing rod 54 away from the support plate 53 is fixedly connected to a limiting plate 57, the size of the plug rod 56 is adapted to the size of the plug hole of the dustproof plate 52, and when the staff pulls the operating panel 55, the operating panel 55 slides on the circular arc surface of the fixing rod 54 At this time, the limit plate 57 has the effect of limiting the maximum sliding distance of the operating plate 55 on the arc surface of the fixing rod 54, thereby preventing the operating plate 55 from detaching from the arc surface of the fixing rod 54 due to excessive pulling force when the staff pulls the operating plate 55. The arc surface of the fixing rod 54 is sleeved with a first spring 58, and the two ends of the first spring 58 are respectively fixedly connected to the operating plate 55 and the support plate 53. When the staff releases the operating plate 55, the rebound force of the first spring 58 drives the operating plate 55 to slide on the arc surface of the fixing rod 54. At the same time, the operating plate 55 drives the insertion rod 56 to move until the insertion rod 56 is inserted into the insertion hole of the dustproof plate 52. At this time, the first spring 58 improves the stability of the insertion rod 56 when limiting the dustproof plate 52.

[0033] Working principle: when the staff needs to clamp the equipment placed on the test machine body 1, they press the soft pad 45, and the soft pad 45 drives the fixing plate 46 to move in the clamping plate 43 until the soft pad 45 fits with the clamping plate 43. At this time, the insert plate 48 is pushed, and the insert plate 48 slides on the inner surface of the sliding groove 47 until the insert plate 48 is inserted into the fixing plate 46. At this time, the handle 44 is turned, and the handle 44 drives the driving rod 41 to move in the inner thread of the test frame 2. At the same time, the driving rod 41 drives the connecting block 42 to move, and the connecting block 42 drives the positioning rod 49 in the test frame 2. The frame 2 slides, and the connecting block 42 drives the clamping plate 43 to move, and the clamping plate 43 drives the soft pad 45 to move, until the soft pad 45 abuts against the equipment placed on the test machine body 1. At this time, the equipment placed on the test machine body 1 is clamped, which avoids the situation that when the staff needs to use the test machine body 1 to test the equipment, the test machine body 1 is hit by the outside world, causing the equipment on the test machine body 1 to be offset, thereby causing the test machine body 1 to test the equipment. The practicability of the device is improved.

[0034] When the staff needs to dust-proof the idle control button 3, they pull the operating panel 55 to make the operating panel 55 slide on the arc surface of the fixing rod 54, the first spring 58 is stretched, and the operating panel 55 drives the insertion rod 56 to move until the insertion rod 56 no longer blocks the movement of the dustproof plate 52. At this time, the dustproof plate 52 is pushed, and the dustproof plate 52 slides in the dustproof frame 51 until the dustproof plate 52 covers the control button 3. At this time, the operating panel 55 is released, and the rebound force of the first spring 58 drives the operating panel 55 to slide on the arc surface of the fixing rod 54. At the same time, the operating panel 55 drives the insertion rod 56 to move until the insertion rod 56 is inserted into the insertion hole of the dustproof plate 52. At this time, the effect of dust-proofing the idle control button 3 is achieved, and the dust is avoided from falling on the surface of the control button 3 when the test machine body 1 is restricted for a long time, causing dust to enter the gap of the control button 3, thereby causing the control button 3 to fail, thereby improving the protection of the device.
