[0046] A transmission rod 42 is fixedly connected to the output end of the first motor 41. A transmission gear 43 is fixedly sleeved on the outer shaft of the transmission rod 42. A limit plate 45 is fixedly fixed to the inner bottom surface of the placement platform 1. Stable linear sliding is achieved through the guidance of the limit plate 45. A toothed plate 44 is slidably sleeved on the outside of the limit plate 45. The toothed plate 44 and the transmission gear 43 mesh with each other. The number of teeth of the transmission gear 43 matches that of the toothed plate 44 to ensure that the two can mesh smoothly and transmit power.

A clamping plate 46 is fixed to the side wall of the L-shaped frame 4. The toothed plate 44 is fixedly connected to the L-shaped frame 4. Therefore, when the toothed plate 44 slides, the L-shaped frame 4 will also slide in the same direction. At the same time, there are two L-shaped frames 4, and they slide in the same direction, which can ensure uniform and stable clamping of the workpiece.

[0047] In this embodiment, as shown in Figure 1 or Figure 2 The driving member includes a rocker 61 fixed to the end side of the lead screw 6.

[0051] A driven bevel gear 1005 is rotatably connected to the outside of a support 1006 fixed to the top wall of the sliding carriage 7, and the driving bevel gear 1004 and the driven bevel gear 1005 are in meshing engagement; a screw rod 1007 is rotatably connected to the top surface of the compression plate 10, and the screw rod 1007 is in threaded connection with the driven bevel gear 1005, and the screw rod 1007 is rotatably connected to the top surface of the compression plate 10 and in threaded connection with the driven bevel gear 1005, when the driven bevel gear 1005 rotates, due to the interaction of the threads, the screw rod 1007 will move up and down along its axial direction, and the compression plate 10 is fixedly connected with the screw rod 1007, and will rise and fall with the screw rod 1007.

[0052] The inside of the driven bevel gear 1005 is provided with external threads matched with the screw rod 1007, and the inside of the sliding carriage 7 is provided with a through hole for facilitating the lifting and sliding of the screw rod 1007, and the design of the through hole needs to consider its size and shape to ensure that the screw rod 1007 can smoothly slide without being hindered during lifting and lowering.

[0053] In this embodiment, as shown in Figure 1 or Figure 2 The scale indicating plate 8 slides vertically with the scale plate 2. The scale plate 2 is marked with evenly distributed scale lines for indicating or measuring length, and the scale indicating plate 8 is a movable component for aligning with the scale lines on the scale plate 2 to display the current length value.

[0057] The manual rotation of the rocker 61 drives the screw rod 6 to rotate in the fixed block 5, the sliding frame 7 on the outside of the threaded sleeve is immediately screwed and cooperates with the screw rod 6 to slide horizontally along the guide rod 62, and the scale indicator plate 8 on the end side of the sliding frame 7 is immediately adjusted to the required length along the scale plate 2, after adjusting to the appropriate length, the second motor 1002 is started to drive the transmission shaft 1003 to rotate the driving bevel gear 1004, thereby driving the driven bevel gear 1005 in mesh with it to rotate, since the driven bevel gear 1005 is provided with external threads in mesh with the screw rod 1007, the rotation of the driven bevel gear 1005 will be converted into the lifting movement of the screw rod 1007, so that the screw rod 1007 drives the pressing plate 10 to lift synchronously and thereby adhere to the top surface of the steel member, the position of the pressing plate 10 corresponds to the position of the scale indicator plate 8, thereby realizing stable comparison of the required length of the steel member, and the worker can cut along the side wall of the pressing plate 10, so that the cutting will not be offset, the process is more stable, and the accuracy of the fixed length cutting is improved.
