[0007] Through the above technical solution, when it is necessary to measure the hexagonal wood screw, the movable plate is pulled to move so as to increase the distance between the movable plate and the fixed plate, and then the hexagonal wood screw is placed between the fixed plate and the movable plate and pre-adsorbed by the adsorption piece, and then the movable plate is released. At this time, the movable plate is pulled to move and fit the hexagonal wood screw by the cooperation of the first spring and the second spring, and the outer diameter of the hexagonal wood screw is measured by observing the position of the movable plate on the scale plate.

The first spring pulls the adsorption member to move and adsorb and fix the hexagonal wood screw, thereby reducing the possibility of the hexagonal wood screw falling out of the device when the operator is measuring the hexagonal wood screw.
[0022] When the operator places the hexagonal wood screw between the fixed plate and the movable plate, the movable plate is loosened. At this time, the first spring and the second spring cooperate to pull the movable plate to move and fit the hexagonal wood screw.

[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] Please refer to the attached figure in the instruction manual Figure 1 、 Figure 2 and Figure 3 , the present application provides an embodiment: a two-stage variable diameter hexagonal wood screw outer diameter measuring device, including a scale plate 1, a fixed plate 2 is fixedly arranged on the scale plate 1, a slide groove 3 is opened on the top surface of the scale plate 1, a movable plate 4 is movably arranged in the slide groove 3, and a plurality of scale bars 11 are provided on the side wall of the scale plate 1. The scale bars 11 facilitate the operator to read the distance between the fixed plate 2 and the movable plate 4, thereby realizing the measurement of the outer diameter of the hexagonal wood screw.
[0029] A limit block 41 is fixedly provided on the bottom surface of the movable plate 4. The limit block 41 is located in the slide groove 3 and slides with the inner wall of the slide groove 3. The limit block 41 cooperates with the slide groove 3 to facilitate limiting the movable plate 4, thereby increasing the stability of the movable plate 4 when moving.
[0030] A reading bar 42 is fixedly provided on the side wall of the movable plate 4, and the reading bar 42 slides with the outer wall of the scale bar 11. When the movable plate 4 moves, the reading bar 42 is driven to move synchronously, and the reading bar 42 cooperates to facilitate reading the distance moved by the movable plate 4, thereby calculating the outer diameter of the hexagonal wood screw, which has six flat surfaces at the end.
[0031] The shape of the inner wall of the chute 3 is adapted to the shape of the limit block 41. The inner bottom wall of the chute 3 is provided with an inclined groove 31. The chute 3 cooperates with the limit block 41 to facilitate limiting the movable plate 4, thereby increasing the stability of the movable plate 4 when moving.
[0032] An adsorption member 5 is provided in the chute 3, one end of which is connected to the inner wall of the chute 3 by means of a first spring 6. The adsorption member 5 includes a movable block 51, a top surface of which is fixedly plugged with an adsorption cylinder 52, a piston disc 53 is movably plugged into the adsorption cylinder 52, the piston disc 53 is connected to the inner bottom wall of the adsorption cylinder 52 by means of a third spring 54, and a resisting rod 55 is fixedly provided on the bottom surface of the piston disc 53, the lower end of which passes through the adsorption cylinder 52 and slides with the inner wall of the chute 31;
[0033] When the first spring 6 pulls the movable block 51 toward the fixed plate 2, the abutment rod 55 is inserted into the inclined slot 31. At this time, the third spring 54 facilitates the downward movement of the piston plate 53 and the abutment rod 55, thereby adsorbing and fixing one surface of the hexagonal wood screw through the adsorption cylinder 52, thereby reducing the possibility of the hexagonal wood screw falling out of the device when the operator is measuring the hexagonal wood screw.
[0034] When the operator pulls the movable plate 4 to move, the movable plate 4 pulls the second spring 7 and the movable block 51 to move, thereby causing the resistance rod 55 to separate from the inclined groove 31, and at the same time, the resistance rod 55 pushes the piston disk 53 upward, thereby causing the adsorption cylinder 52 to lose adsorption, thereby making it easier for the operator to pick up the hexagonal wood screw.
[0035] A suction cup 56 is fixedly provided on the top surface of the adsorption cylinder 52, and the suction cup 56 facilitates pre-adsorption of one surface of the hexagonal wood screw, so that the operator does not need to support the hexagonal wood screw all the time when loosening the movable plate 4 to clamp the hexagonal wood screw.
[0036] The other end of the adsorption member 5 is connected to the movable plate 4 by setting a second spring 7. When the operator releases the movable plate 4, the adsorption member 5 is pulled to move by the first spring 6, and cooperates with the second spring 7 to pull the movable plate 4 to move and fit with the hexagonal wood screw. Then, the outer diameter of the hexagonal wood screw is measured by observing the position of the movable plate 4 on the scale plate 1.
[0037] Working Principle: When using the two-stage variable diameter hexagonal wood screw outer diameter measuring device, when the hexagonal wood screw needs to be measured, the movable plate 4 is pulled to move to increase the distance between the movable plate 4 and the fixed plate 2, and then the hexagonal wood screw is placed between the fixed plate 2 and the movable plate 4 and pre-adsorbed by the adsorption member 5;
[0038] Then release the movable plate 4. At this time, the first spring 6 and the second spring 7 cooperate to pull the movable plate 4 to move and fit with the hexagonal wood screw. As the first spring 6 pulls the adsorption part 5 to move, the hexagonal wood screw is adsorbed and fixed for the second time, thereby reducing the possibility of the hexagonal wood screw falling out of the device when the operator measures the hexagonal wood screw, and the outer diameter of the hexagonal wood screw is measured by observing the position of the movable plate 4 on the scale plate 1.
[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
