[0001] The utility model relates to the field of hand tools, and particularly to a woodworking angle saw with an improved structure. Background Art

[0002] With the development of technology, each industry is constantly innovating its processing tools to improve efficiency and usability. In the field of hand tools, as one of the tools, the angle saw has undergone long-term innovation and development, and various types of angle saws have emerged. In the prior art, although there are many types of angle saws, there are still some inconveniences or low efficiency problems in the actual use process, and these problems need to be solved.

[0003] Chinese Patent CN217621056U discloses a woodworking angle saw. The working principle of the woodworking angle saw described in the document is to use the indexing plate and multiple limiting components on the base to achieve rapid multi-angle processing of wood. Specifically, the angle saw includes a base, a first limiting component, a second limiting component, and a third limiting component. These components are all provided on the top surface of the base. The first limiting component is located on the left side of the third limiting component, the second limiting component is located on the right side, and a 45-degree angle is formed between the second limiting component and the third limiting component. The first limiting component is provided with a vertical first baffle plate, one end of which is rotatably arranged at the center of the indexing plate, allowing the baffle plate to rotate to different angles to meet the processing requirements of the wood. The second limiting component is provided with a vertical second baffle plate, and a horizontal limiting plate is provided at its lower end, which is fixedly installed in the limiting groove to provide stable support. The third limiting component is provided with two vertical limiting columns, which are respectively installed in the first limiting holes on the base, and the two groups of limiting columns are parallel to each other to provide positioning in the vertical direction for the wood. In order to achieve rapid adjustment and fixing of the angle, two parallel sliding blocks are provided at the bottom of the first limiting component, and the sliding blocks are installed in the sliding grooves on the indexing plate. By pushing the sliding blocks, the angle of the first baffle plate can be adjusted. A groove for installing a limiting block is also provided at the bottom end of the first baffle plate. The limiting block slides in the groove, and a convex block is provided on one side thereof, which cooperates with the second limiting hole on the indexing plate to achieve fine adjustment of the angle. In addition, two fixing components are respectively provided on the first baffle plate and the second baffle plate, including a horizontal threaded rod and a support rod. One end of the threaded rod is provided with a clamping block, and the other end is provided with a rotating column. By rotating the rotating column, the clamping block can be tightened to fix the wood. A soft pad is provided on the clamping block to protect the surface of the wood from damage during the clamping process. Multiple vertical support legs are provided at the bottom of the base, and threaded columns are installed at the bottom ends of the support legs. Anti-slip pads are provided at the lower ends of the threaded columns. These designs enable the entire device to adjust the height and maintain stability, preventing movement or sliding during work.

[0004] The fixing method of the multi-angle adjusting mechanism in this patent document is relatively simple. The simplicity results in the inability to guarantee the fixing effect, and the clamping device has a large limitation on the material specifications and can only clamp materials with smaller specifications. Summary of the Utility Model

[0005] In view of the above problems, a woodworking angle saw with an improved structure is provided, which includes a base. An multi-angle clamping mechanism and a fixed-angle clamping mechanism are provided on the base. The multi-angle clamping mechanism includes an angle adjustment groove opened on the base. An angle adjustment base is arranged in the angle adjustment groove. The angle adjustment base can slide in the angle adjustment groove. A number of angle adjustment holes are opened on the side of the angle adjustment groove. Positioning holes adapted to the models of the angle adjustment holes are opened on the angle adjustment base. A positioning rod is inserted into the positioning holes. The positioning rod is inserted into the angle adjustment holes on the side of the base through the positioning holes. A through hole is provided at one end of the positioning rod away from the base for the operator's finger to insert to facilitate the pulling and drawing of the positioning rod. A return spring is arranged between the positioning rod and the angle adjustment base. When the return spring is not compressed or stretched, the positioning rod is in the angle adjustment hole.

[0006] Preferably, the multi-angle clamping mechanism includes a material clamping mechanism. The material clamping mechanism includes an adjustable material stop arranged on the angle adjustment base. A guiding through hole is opened on the adjustable material stop. A threaded guiding rod is inserted into the guiding through hole. A clamping block is fixedly connected to one side of the threaded guiding rod. A nut is threadedly connected to the part of the threaded guiding rod passing through the guiding through hole. By rotating the nut, the clamping block approaches the adjustable material stop to clamp the material between the clamping block and the adjustable material stop.

[0007] Preferably, a guiding groove is opened on the threaded guiding rod. A guiding block adapted to the specifications of the guiding groove is arranged in the guiding through hole. Only when the insertion angle of the threaded guiding rod is correct can the threaded guiding rod pass through the guiding through hole. After insertion, the threaded guiding rod cannot rotate relative to the guiding through hole.

[0008] Preferably, the fixed-angle clamping mechanism is a 45-degree angle material stop arranged on the base. When 45-degree angle processing is required, the material is directly clamped by the fixed-angle clamping mechanism arranged on the base. A guiding through hole is opened on the 45-degree angle material stop.

[0009] Preferably, a saw blade limiting block is arranged on the base. The saw blade limiting block is used to limit the position of the saw blade to prevent the saw blade from deviating from the established position during the processing.

[0010] Preferably, support feet are arranged at the bottom of the base. The support feet are used to support the whole device.

[0011] The beneficial effects of the present utility model compared with the prior art are:

[0012] 1. The utility model realizes rapid and precise angle adjustment of materials by setting a multi-angle clamping mechanism with an angle adjustment groove and an angle adjustment base on the base. The angle adjustment holes on the side of the angle adjustment groove are used in conjunction with the positioning holes on the angle adjustment base. Through the insertion of the positioning rod, it can be firmly fixed at any desired angle.

Detailed implementation manners

[0022] To further understand the features, technical means, specific purposes and functions achieved by the present utility model, the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0023] Refer to Figures 1-6 : A woodworking angle saw with an improved structure, comprising a base 1, a multi-angle clamping mechanism 2 and a fixed-angle clamping mechanism 3 are provided on the base 1. The multi-angle clamping mechanism 2 includes an angle adjustment groove 21 opened on the base 1. An angle adjustment base 22 is provided in the angle adjustment groove 21. The angle adjustment base 22 can slide in the angle adjustment groove 21. A plurality of angle adjustment holes 23 are opened on the side of the angle adjustment groove 21. A positioning hole 221 adapted to the type of the angle adjustment hole 23 is opened on the angle adjustment base 22. A positioning rod 24 is inserted into the positioning hole 221. The positioning rod 24 is inserted into the angle adjustment hole 23 on the side of the base 1 through the positioning hole 221. A through hole 241 is provided at one end of the positioning rod 24 away from the base 1. The through hole 241 is used for the operator to insert a finger to facilitate the pulling and pushing of the positioning rod 24. A return spring 25 is provided between the positioning rod 24 and the angle adjustment base 22. When the return spring 25 is not compressed or stretched, the positioning rod 24 is in the angle adjustment hole 23.

[0024] In the comparative document, the fixing effect of the multi-angle clamping mechanism 2 is not reliable and may cause looseness during the processing. In this utility model, an angle adjustment groove 21 is provided on the base 1, and a slidable angle adjustment base 22 is installed in the groove. A number of angle adjustment holes 23 are provided on the side of the angle adjustment groove 21, and positioning holes 221 adapted to the model of the angle adjustment holes 23 are provided on the angle adjustment base 22. A positioning rod 24 passes through the positioning hole 221 on the angle adjustment base 22 and is inserted into the angle adjustment hole 23 on the side of the base 1, thereby allowing the positioning rod 24 to move within the angle adjustment hole 23 to adjust the angle. A through hole 241 is provided at one end of the positioning rod 24 away from the base 1, and this through hole 241 allows the operator to insert a finger to facilitate pulling out the positioning rod 24 so that the positioning rod 24 is inserted into different angle adjustment holes 23, thereby adjusting the angle of the multi-angle clamping mechanism 2. A return spring 25 is installed between the positioning rod 24 and the angle adjustment base 22. When the return spring 25 is not compressed or stretched, the positioning rod 24 will maintain its position within the angle adjustment hole 23. Such a structural design enables the woodworking angle saw to perform quick adjustment and clamping at multiple angles to adapt to the cutting requirements at different angles and improve work efficiency.

[0025] Refer to Figures 1-6 : The multi-angle clamping mechanism 2 includes a material clamping mechanism 4. The material clamping mechanism 4 includes an adjustable material stop 41 provided on the angle adjustment base 22. A guiding through hole 42 is provided in the adjustable material stop 41. A threaded guiding rod 43 is inserted into the guiding through hole 42. One side of the threaded guiding rod 43 is fixedly connected to a clamping block 44. The part of the threaded guiding rod 43 that passes through the guiding through hole 42 is threadedly connected to a nut 45. By rotating the nut 45, the clamping block 44 approaches the adjustable material stop 41, and the material between the clamping block 44 and the adjustable material stop 41 is clamped.

[0026] The material clamping mechanism 4 is composed of an adjustable material stop 41 provided on the angle adjustment base 22, and a guiding through hole 42 is provided in this material stop. A threaded guiding rod 43 is inserted into these guiding through holes 42, and a clamping block 44 is fixedly connected to one side of these threaded guiding rods 43. After the threaded guiding rod 43 passes through the guiding through hole 42, the part that passes through the adjustable material stop 41 is threadedly connected to a nut 45. By rotating the nut 45, the threaded guiding rod 43 will move along the axial position of the guiding through hole 42, thereby approaching the adjustable material stop 41. In this way, the material located between the clamping block 44 and the adjustable material stop 41 is clamped, achieving a stable clamping for precise cutting operations.

[0027] Refer to Figures 1-6: A guiding groove 46 is formed on the threaded guiding rod 43, and a guiding block 47 adapted to the specification of the guiding groove 46 is provided in the guiding through hole 42. Only when the insertion angle of the threaded guiding rod 43 is correct can the threaded guiding rod 43 pass through the guiding through hole 42. After insertion, the threaded guiding rod 43 cannot rotate relative to the guiding through hole 42 any more.

[0028] In the improved structure of the woodworking corner saw, a guiding groove 46 is provided on the threaded guiding rod 43, and the guiding groove 46 is adapted to the specification of the guiding block 47 provided in the guiding through hole 42. When the threaded guiding rod 43 is correctly inserted into the guiding through hole 42, the guiding groove 46 and the guiding block 47 cooperate with each other to ensure that the threaded guiding rod 43 can smoothly pass through the guiding through hole 42 only when it is at the correct insertion angle. Once the threaded guiding rod 43 is inserted in place, due to the cooperation of the guiding groove 46 and the guiding block 47, the threaded guiding rod 43 cannot rotate relative to the guiding through hole 42 any more, thus ensuring the stability of the clamping mechanism and the accuracy of operation. This design improves the positioning accuracy of the clamping mechanism and prevents the unstable clamping of the workpiece or machining errors that may be caused by the incorrect angle of the threaded guiding rod 43.

[0029] Refer to Figure 1 and Figure 2 : The fixed-angle clamping mechanism 3 is a 45-degree angle material stop 31 provided on the base 1. When machining at a 45-degree angle is required, the workpiece is directly clamped by the fixed-angle clamping mechanism 3 provided on the base 1. A guiding through hole 42 is formed on the 45-degree angle material stop 31.

[0030] A 45-degree angle material stop 31 is provided on the base 1, which is specifically used to achieve precise machining at a 45-degree angle. When the operator needs to machine the workpiece at a 45-degree angle, the workpiece can be directly placed on the fixed-angle clamping mechanism 3 on the base 1 for clamping. The 45-degree angle material stop 31 is also provided with a guiding through hole 42, which is the same as the guiding through hole 42 in the multi-angle clamping mechanism 2 and is used to cooperate with components such as the guiding block 47 and the guiding rod to ensure the position accuracy and stability of the workpiece during clamping. In this way, the woodworking corner saw can quickly switch to the fixed-angle machining mode, improving the machining efficiency and ensuring the machining quality.

[0031] Refer to Figure 2 : A saw blade limiting block 5 is provided on the base 1, and the saw blade limiting block 5 is used to limit the position of the saw blade to prevent the saw blade from deviating from the established position during machining.

[0032] The base 1 of the woodworking angle saw is provided with a saw blade limiting block 5. The main function of this component is to limit the position of the saw blade during the processing, ensuring that the saw blade cuts along a predetermined trajectory. By setting the saw blade limiting block 5, the saw blade can be effectively prevented from shifting during cutting, thereby avoiding processing errors or damaging the workpiece. This limiting mechanism improves the processing accuracy and safety, ensuring the reliability of the woodworking angle saw during complex or delicate processing.

[0033] Refer to Figure 1 and Figure 2 : The bottom of the base 1 is provided with a support leg 6, and the support leg 6 is used to support the entire device.

[0034] The setting of the support leg 6 provides a stable foundation for stable processing.

[0035] The above embodiments only represent one or several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
