[0010] In a preferred embodiment, a bracket is fixedly installed on the outer side of the frame, the motor is installed on the inner side of the bracket, and a handle is installed on the outer side of the frame.
[0011] By adopting the above technical solution, the motor can be positioned using a bracket, ensuring the stability of the motor during operation and preventing it from easily shifting or shaking in position. Furthermore, the handle makes it convenient for users to hold the device while working.
[0012] In a preferred embodiment, a turntable is fixedly mounted on the top of the stud.
[0013] By adopting the above technical solution, it is easy for users to rotate the stud to adjust the position of the pressure plate, thereby facilitating the positioning of the wood placed inside the frame and ensuring stability during cutting.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0026] Reference Figure 1-5 A handheld wood testing sample preparation machine includes a frame 1, a motor 2 mounted on the outside of the frame 1, a lead screw 3 fixedly connected to the power output shaft of the motor 2, a slider 4 threadedly connected to the outer edge of the lead screw 3, a cutter 5 fixedly mounted on the outside of the slider 4, a horizontal plate 12 mounted on the top of the frame 1, a fixing plate 13 mounted on the top of the horizontal plate 12, studs 14 threadedly connected to the inner walls of the horizontal plate 12 and the fixing plate 13, a pressure plate 15 rotatably connected to the bottom of the studs 14, an mounting plate 20 fixedly mounted on the top of the frame 1, a positioning frame 17 fixedly mounted on the top of the mounting plate 20, a cylinder 18 mounted on the top of the positioning frame 17, and a cutter 19 fixedly connected to the power output shaft of the cylinder 18.
[0027] See Figure 1 and Figure 3 A limiting block 6 is fixedly connected to the side of the cutter 5 away from the slider 4. A limiting rod 7 is fixedly installed on the outer wall of the frame 1. The limiting block 6 is slidably connected to the outer edge of the limiting rod 7. A guide groove 9 is provided on the inner wall of the frame 1. The cutter 5 is slidably connected to the inner wall of the guide groove 9, so that it can be used to limit the movement of the cutter 5, thereby ensuring that both sides of the cutter 5 can move synchronously and stably on the inner wall of the guide groove 9, for cutting the wood placed inside the frame 1.
[0028] See Figure 2 A side plate 8 is fixedly installed on the outer side of the frame 1. A limit ring is fixedly installed on the outer wall of the side plate 8. The end of the lead screw 3 away from the motor 2 is rotatably connected to the inner wall of the limit ring, so that the lead screw 3 can be used to limit the rotation of the lead screw 3, ensuring the stability of the lead screw 3 during rotation, and thus ensuring that the lead screw 3 will not easily shift or swing in position during rotation.
[0029] See Figure 2 A bracket 10 is fixedly installed on the outside of the frame 1, and the motor 2 is installed on the inside of the bracket 10. A handle 11 is installed on the outside of the frame 1, so that the motor 2 can be positioned by the bracket 10, ensuring the stability of the motor 2 during operation and preventing it from easily shifting or shaking in position. Furthermore, the handle 11 makes it easier for the user to hold the device for operation.
[0030] See Figure 4 A turntable 16 is fixedly installed on the top of the stud 14, which makes it easy for the user to rotate the stud 14 to adjust the position of the pressure plate 15, thereby facilitating the positioning of the wood placed inside the frame 1 and ensuring stability during cutting.
[0031] See Figure 5 The inner wall of the mounting plate 20 is provided with a through groove. The second cutter 19 is slidably inserted into the inner wall of the through groove, so that the second cutter 19 can pass through the through groove and contact the wood to cut the wood. With the cutting marks of the first cutter 5, the wood can be easily removed.
[0032] Working principle: When using this device, the wood can first be placed inside the frame 1. Then, the turntable 16 can be rotated to drive the stud 14 to rotate, thereby adjusting the pressure plate 15 to move downward and abut against the top of the wood to position the wood. Then, the motor 2 can be driven to drive the lead screw 3 to rotate. When the lead screw 3 rotates, it can drive the slider 4 and the first cutter 5 to move to cut the wood. When the first cutter 5 moves below the second cutter 19, the cylinder 18 can be driven to drive the second cutter 19 to move downward to cut the wood. Thus, the wood can be directly removed, and the cut can be kept flat to ensure the accuracy of the test data.
