[0025] Furthermore, the lifting assembly includes a screw 6, a screw sleeve 7 and a fixed plate 8. The front end of the working chamber 2 is rotatably mounted with the screw 6, the lower end of the screw 6 is threadedly mounted with the screw sleeve 7, the front side of the screw sleeve 7 is fixedly mounted with the fixed plate 8, and the upper end of the screw 6 is provided with a handle, such as Figure 5 As shown, this arrangement can control the height of the fixing plate 8, thereby facilitating subsequent measurement of shafts of different sizes.
[0026] Furthermore, two sets of limit blocks 9 are symmetrically fixed on the rear side of the fixed plate 8, and two sets of limit slots 10 are symmetrically opened on the front side of the working chamber 2. The limit blocks 9 slide inside the limit slots 10. Figure 5 As shown, this arrangement facilitates ensuring the stability of the fixing plate 8 during lifting.
[0027] Furthermore, a movable groove 18 is provided inside the workbench 1, a sliding plate 19 is slidably mounted on the upper side of the movable groove 18, an electric telescopic rod 20 is provided on the lower side of the movable groove 18, and the front side of the electric telescopic rod 20 is fixedly connected to the lower side of the sliding plate 19, as shown in FIG. Figure 3 As shown, the electric telescopic rod 20 drives the sliding plate 19 to slide inside the working chamber 2, thereby pushing the shaft product 4 out from the discharge port 5.
[0028] Furthermore, the right ends of the two sets of rotating shafts 12 on the lower side are fixedly mounted with circular plates 15, and the outer wall array of the circular plates 15 is provided with multiple sets of quasi-grooves 16, and the first teeth 17 are rotatably mounted inside the multiple sets of quasi-grooves 16. The upper side array of the sliding plate 19 is provided with multiple sets of second teeth 21, and the first teeth 17 are meshed with the second teeth 21. Figure 4 and Figure 6 As shown, this arrangement makes it easy for the sliding plate 19 to move rearward while driving the two groups of circular plates 15 to rotate counterclockwise, thereby facilitating better pushing out the shaft product 4.
[0029] Furthermore, a rotating plate 22 is rotatably mounted on the upper side of the rear end of the sliding plate 19, a first spring 23 is provided on the front side of the rotating plate 22, and a limiting plate 24 is provided on the rear end of the sliding plate 19.

[0030] Furthermore, a movable plate 25 is provided inside the feed port 3, and four groups of slots 26 are symmetrically provided on the left side of the working bin 2. Second springs 27 are movably installed inside the four groups of slots 26, and rods 28 are movably inserted inside the four groups of slots 26. The front sides of the four groups of rods 28 are fixedly installed with the rear side of the movable plate 25, as shown in FIG. Figure 8 As shown, through this setting, the shaft products 4 entering the feed port 3 can be adjusted so that multiple groups of shaft products 4 remain parallel inside the feed port 3.
[0031] Working principle: When the device is used, the staff will put the multiple groups of shaft products 4 that need to be measured into the inside of the feeding port 3 in turn. The four groups of insertion rods 28 are driven by the elastic force of the four groups of second springs 27 inside the four groups of slots 26 to drive the movable plate 25 to move to the right, so that the positions of the multiple groups of shaft products 4 can be adjusted. Then the staff will adjust the position of the fixed plate 8 according to the shaft to be measured. When the measured shaft size is small, the staff will grasp the turning handle to drive the screw 6 to rotate clockwise, and the screw sleeve 7 on the screw 6 will drive the fixed plate 8 to move downward under the action of the thread. When the shaft size to be measured is large, just grasp the turning handle to rotate counterclockwise. Then the staff will start the electric telescopic rod 20, and the front side of the electric telescopic rod 20 will drive the arc-shaped fixed block 29 to move forward. Through the setting of the turning plate 22, the shaft products 4 at the bottom layer can be pushed forward, and the shaft products 4 can be pushed out from the discharge port 5. The upper and lower sides of the shaft products 4 are aligned with the The four groups of rubber rings 13 fit together, and through the pushing effect, the four groups of rotating shafts 12 and rubber rings 13 are driven to rotate at the same time. The shaft products 4 can be measured by the setting of the infrared measuring instrument 11. Subsequently, the staff starts the electric telescopic rod 20 to control the sliding plate 19 to reset, and the multiple groups of second teeth 21 engage with the teeth of the first teeth 17. When the sliding plate 19 moves to the rear side, it drives the two groups of circular plates 15 to rotate counterclockwise, thereby facilitating the conveying of the shaft products 4 to the front side. When the shaft products 4 are completely conveyed, the other group of shaft products 4 moves downward under gravity, and the sliding plate 19 drives the rotating plate 22 to move backward. The rotating plate 22 rotates counterclockwise by the force of the lower shaft products 4 and compresses the first spring 23. When the sliding plate 19 is reset, the rotating plate 22 is reset by the elastic force of the first spring 23, and the above operation can be repeated for measurement. The above is the entire working principle of the present utility model.
