[0022] In this embodiment, the tester body 1 includes an A box 11, a handle 12, a buckle 13 and a clamping block 14, and the A box 11 is hingedly mounted with a B box 111;

[0023] The handle 12 makes it convenient for the staff to move the device as a whole, the A box 11 makes it convenient to store items, and the partition 112 makes it convenient to separate each item to prevent the items from piling up and being difficult to take out.

[0024] In this embodiment, the handle 12 and the side of the buckle 13 close to the B box 111 are fixedly connected to the side of the A box 11, and a partition plate 112 is fixedly installed inside the A box 11.

[0025] In this embodiment, one end of the telescopic spring 33 close to the block 14 is fixedly connected to the side surface of the B box 111, the bottom surface of the block 14 is fixedly connected to the top surface of the B box 111, and the outer surface of the block 14 is clamped to the inside of the buckle 13.

[0026] Specifically, through the arrangement of the buffer pad 32 and the protective plate 31, when the device is impacted by the outside world, it can effectively prevent the impact force from contacting the device body in the first place, and through the buffering of the buffer pad 32 itself, and the mutual cooperation between the protective plate 31 and the telescopic spring 33, it can effectively provide a certain protection effect on the device body.

[0027] Example 2, please refer to the attached Figure 1 -Attached Figure 4A locking force tester includes a tester body 1, a limit assembly 2 and a protection assembly 3 are respectively installed inside and on the side of the tester body 1, the protection assembly 3 includes a protection plate 31, a buffer pad 32 and a telescopic spring 33, the top surface of the telescopic spring 33 is fixedly connected to the bottom surface of the protection plate 31, the top surface of the protection plate 31 is fixedly connected to the bottom surface of the buffer pad 32, and the protection plate 31 is located at the connection between the telescopic spring 33 and the buffer pad 32.

[0028] In this embodiment, the limiting assembly 2 includes a limiting plate 21, a fixed cylinder 22, a movable spring 23 and a movable column 24, one end of the movable column 24 away from the fixed cylinder 22 is fixedly connected to the side of the limiting plate 21, and the other end of the movable column 24 is fixedly connected to one end of the movable spring 23;

[0029] Through the cooperation between the limiting plate 21 and the movable spring 23, the position of the objects inside the partition 112 can be restricted to prevent the objects inside from shaking during the movement of the device.

[0030] In this embodiment, the other end of the movable spring 23 is fixedly connected to the inner wall of the fixed tube 22 , and one end of the fixed tube 22 away from the movable column 24 is fixedly connected to one side of the partition 112 .

[0031] Specifically, through the arrangement of the limit plate 21, the movable spring 23, the movable column 24 and the fixed cylinder 22, when the limit plate 21 contacts the object, the limit plate 21 continuously approaches the object under the drive of the movable column 24 and the movable spring 23, and limits the position of the object to a certain extent through the extensibility of the movable spring 23, thereby preventing the internal objects from shaking and causing damage to the device as a whole during the movement.

[0032] Working principle:

[0033] First, the staff puts the tool into the interior of the partition 112. When the outer surface of the tool contacts the side of the limit plate 21, the limit plate 21 will be displaced outward as a whole due to its own volume, so that the tool can smoothly enter the interior of the A box 11. Then, the movable column 24 and the elasticity of the movable spring 23 are used to apply an inward pressure to the limit plate 21. Driven by the movable spring 23, the limit plate 21 will limit the position of the tool inside the A box 11. Then, when the buffer pad 32 and the protective plate 31 are hit, the buffer pad 32 will convert the impact force it receives into thrust, and drive the protective plate 31 and the telescopic spring 33 to be displaced as a whole. At this point, the entire workflow ends.
