The rear end of the slide bar 22 is fixedly connected to a limit block 24, and the limit block 24 is slidably connected to the inner wall of the slide groove 12. The rear end surface of the limit block 24 is fixed A first elastic component 26 is fixedly connected, and one end of the first elastic component 26 is fixedly connected to the rear wall of the slide groove 12 away from the limit block 24. The frame 21 slides in the slide groove 12, which makes it convenient to take the frame 21 out of the inner cavity of the box body 11. The limit block 24 prevents the entire frame 21 from sliding out of the box body 11. The anti-drop component 3 is installed at intervals on the upper end surface of the frame 21 to fix the workpiece and prevent the workpiece from falling. The limit components 4 are installed on both sides of the front end of the frame 21 to lock the frame 21 to prevent the frame 21 from spontaneously popping out of the box body 11.

[0026] It should be noted that the height of the limit block 24 is equal to the height of the slide groove 12 , the height of the limit groove 15 is equal to the height of the slide bar 22 , and the height of the slide bar 22 is less than the height of the limit block 24 .

[0027] For details, please refer to 4 and Figure 5 In order to prevent the workpiece from falling from the upper end of the frame 21, a plurality of groups of adjusting grooves 23 are spaced apart on the upper end surface of the frame 21, and two groups of moving grooves 25 are symmetrically provided on the side walls of the adjusting grooves 23. The anti-drop component 3 includes a base 31, and two groups of sliders 32 are symmetrically fixedly connected to the front and rear end surfaces of the base 31. The sliders 32 slide and move inside the moving grooves 25. Two groups of air bags 34 are symmetrically fixedly connected to the inner cavity of the base 31. Avoidance grooves 33 are provided at the bottom of the base 31. The workpiece is inserted from the adjacent positions of the two groups of air bags 34 and partially extends out through the avoidance grooves 33. The deformed air bags 34 clamp the workpiece to prevent it from falling off. When the workpiece needs to be moved, the position of the workpiece can be adjusted by pushing the base 31, thereby improving the convenience of use.

[0028] It should be noted that the outer side of the airbag 34 is arc-shaped, and can wrap and clamp workpieces of different shapes.

[0029] It should also be noted that the airbag 34 is made of a wear-resistant and elastic material.

[0030] For details, please refer to Figure 6In order to prevent the frame 21 from spontaneously popping out from the front end of the box body 11, the limiting component 4 includes a baffle 42, the baffle 42 is slidably connected in the placement groove 13, the top of the baffle 42 is fixedly connected to a second elastic component 43, the second elastic component 43 is fixedly connected to the top of the placement groove 13 at one end away from the baffle 42, and the front end of the baffle 42 is fixedly connected to an adjusting rod 41, the adjusting rod 41 passes through the adjusting groove 14 and extends to the outside of the box body 11. By holding the adjusting rod 41 and moving it upward, the baffle 42 can be controlled to compress the second elastic component 43 and move upward. When the baffle 42 moves to the top of the frame 21, the compressed first elastic component 26 pushes the limit block 24 to slide outward along the slide groove 12, so that the frame 21 partially extends to the outside of the box body 11, which is convenient for adjusting and selecting the workpiece placed on the upper end surface of the frame body 21. After completion, the frame body 21 is held and pushed into the slide groove 12. When the front end of the frame body 21 moves past the lower end surface of the baffle 42, the deformed second elastic component 43 pushes the baffle 42 to move downward, and the baffle 42 moves back to the front end of the frame body 21 to prevent the frame body 21 from popping out of the box body 11.

[0031] It should be noted that the height of the baffle plate 42 is greater than the height of the limiting groove 15 to prevent the frame body 21 from pushing the baffle plate 42 to slide out of the limiting groove 15 .

[0032] Principle: The adjusting rods 41 on both sides of the hand-held frame 21 slide upward along the adjusting groove 14, so that the baffle 42 compresses the second elastic component 43 and moves upward along the placement groove 13. When the moving height of the baffle 42 exceeds the thickness of the frame 21, the compressed first elastic component 26 pushes the limit block 24 to move along the slide groove 12 to the outside of the box 11. At the same time, the front end of the slide bar 22 passes through the limit groove 15 to move part of the frame 21 to the outside of the box 11, and the workpiece is inserted downward from the adjacent area of ​​the two groups of air bags 34, forming The transformed airbag 34 wraps and clamps the workpiece, and at the same time pushes the base 31 so that the slider 32 slides along the movable groove 25 to adjust the position of the workpiece. After the workpiece is installed, the front end of the handheld frame 21 pushes the frame 21 into the box body 11. When the front end of the frame 21 passes the lower end surface of the baffle 42, the compressed second elastic component 43 pushes the lower baffle 42 to move, so that the baffle 42 moves to the front end of the frame 21, limiting the frame 21 and preventing the frame 21 from popping out from the box body 11.
