[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-3As shown in the embodiment of this utility model, a hand saw fixture for cutting irregularly shaped wooden blocks includes: a base 7, a fixing post 2 3 fixedly disposed in the middle of one side of the top of the base 7, and a fixing post 1 2 fixedly disposed at one end of one side of the top of the base 7. An adjusting rod 1 is rotatably disposed on the top of both the fixing post 2 3 and the fixing post 1 2. The end of the adjusting rod 1 is threaded through a threaded rod 5 for fixing irregularly shaped wooden blocks. Through the cooperation of the fixing post 2 3, the fixing post 1 2, the adjusting rod 1 and the threaded rod 1 5, various fixing positions and angles can be adjusted. The fixing post 1 2 can be adjusted to rotate circumferentially according to the size of the wooden blocks of different shapes, and the threaded rod 1 5 can be adjusted to move up and down according to the size of the wooden blocks of different shapes, providing a flexible and versatile fixing method.

[0028] A handle 4 is fixedly installed at the top of the threaded rod 5. Damping bearings 17 are fixedly fitted onto the top circumference of both the fixed post 3 and the fixed post 2, with the outer circumference of the damping bearings 17 fixedly connected to the inner wall of the hole on one side of the bottom of the adjusting rod 1. A support plate 8 is fixedly installed on one side of the top of the base 7 by bolts, a support plate 9 is fixedly installed in the middle of the top of the base 7 by bolts, and a protective plate 16 is fixedly installed on the side of the top of the base 7 away from the support plate 8 by bolts. The bottom of the fixed post 2 is threaded into the support plate 8, and the bottom of the fixed post 3 is threaded into the base 7. An angle adjusting seat 10 is fixedly installed on the base 7 by bolts, with one side of the angle adjusting seat 10 fitting against one side of the support plate 9. A first angle adjusting block 11 is movably inserted into the angle adjusting seat 10. The inclined surface of the first angle adjusting block 11 allows for easy leverage during hand saw cutting, and the first angle adjusting block 11 can be quickly inserted and removed for convenient use.

[0029] A measuring ruler 15 is fixedly installed on the top of the support plate 8 near the first angle adjustment block 11. A groove seat 12 is fitted on the measuring ruler 15. A positioning block 13 is fixedly installed on one side of the groove seat 12. A threaded rod 14 passes through the groove seat 12. A pressure plate 6 is fixedly installed at the bottom of the threaded rod 15 and the end of the threaded rod 14. Through the cooperation of the measuring ruler 15, the groove seat 12, the positioning block 13, the threaded rod 14 and the pressure plate 6, the size of the object to be cut can be measured conveniently and quickly. When measuring irregularly shaped wooden blocks, the end of the wooden block can be placed in the gap between the support plate 8 and the support plate 9. The other side is supported by the positioning block 13, which drives the groove seat 12 to press against the irregularly shaped wooden block. The edge of the positioning block 13 is the size of the object at that position.

[0030] One side of the first angle adjustment block 11 is a straight surface, and the other side is an inclined surface. A first magnetic ring 11a is fixedly connected to the top of the inclined surface, and a hand saw is attached to the first magnetic ring 11a.

[0031] A rubber pad with tooth marks can be fixedly installed at the bottom of the pressure plate 6;

[0032] The height of the second fixing post 3 can be set to be the same as that of the first threaded rod 5. The irregular object has an unspecified shape. Through the cooperation between the first threaded rod 5 and the adjusting rod 1, the two first threaded rods 5 can be adjusted to different heights to press against the irregular object and fix it. The first threaded rod 5 with the pressure plate 6 can be removed and a first threaded rod without the pressure plate 6 can be installed. Alternatively, the pressure plate 6 can be threadedly connected to the first threaded rod 5 for easy disassembly. When the pressure plate 6 is not needed, only the first threaded rod 5 is used to press against and fix the irregular object.

[0033] The first step is to place the wooden block on one side of the measuring ruler 15, move the positioning block 13 and the groove seat 12, measure the size of the wooden block to be cut, and then tighten the threaded rod 14 and the threaded rod 5 on the threaded rod 14.

[0034] The second step is to place the wooden block on the support plate 29 and the support plate 18, rotate and adjust the position of the two adjustment rods 1, and turn the two handles 4 to drive the threaded rod 15 and the pressure plate 6 to press the wooden block.

[0035] The third step is to insert the first angle adjustment block 11 into the angle adjustment seat 10 according to the required cutting angle, and use the handsaw to cut the wood block by using the side of the first angle adjustment block 11 for leverage.

[0036] Support plate 8 and support plate 9 serve to support the wooden blocks, and protective plate 16 prevents damage to base 7 during cutting and facilitates replacement.

[0037] The bottom of pressure plate 6 has serrated edges. Pressure plate 6 can be made of medium carbon steel with a tensile strength of 400-600 MPa, suitable for medium-to-high load applications. Hardness and toughness can be improved through quenching and tempering; for example, 45 steel can achieve a hardness of 32-39 HRC after heat treatment. It is suitable for general mechanical clamping, such as machine tool fixtures and steel structure connections, and is commonly used for bolts of grade 8.8 and above. Pressure plate 6 can also be made of medium carbon alloy steel. Adding chromium and molybdenum significantly improves strength and high-temperature resistance; for example, 40Cr steel has a tensile strength ≥1000 MPa, a yield strength ≥900 MPa, and can withstand temperatures above 200℃.
