The front and rear end faces of the saw blade fixing block 1 are provided with saw blade fixing grooves 11. The bottom surface of the saw blade fixing block 1 is provided with a first saw blade positioning hole 12. The connecting strip 3 is provided with a second saw blade positioning hole 32. The saw blade 2 is fixed in the saw blade fixing groove 11 of the saw blade fixing block 1. The connecting strip 3 presses the saw blade 2 and the saw blade fixing block 1 together. The connecting strip 3 and the saw blade fixing block 1 are connected by a saw blade locking screw assembly 23. The first saw blade positioning point 21 of the saw blade 2 is locked in the first saw blade positioning hole 12. The second saw blade positioning point 22 of the saw blade 2 is locked in the second saw blade positioning hole 32. The connecting strip 3 is connected to the power unit.

[0022] Preferably, the saw blade fixing block 1 is one of the core components of this assembly and is made of high-strength metal material. The front and rear ends of the saw blade fixing block 1 are respectively provided with saw blade fixing grooves 11 for accurately installing the saw blade 2. These saw blade fixing grooves 11 ensure the saw blade is firmly fixed within them, preventing loosening or displacement during use. The bottom surface of the saw blade fixing block 1 is provided with a first saw blade positioning hole 12, which engages with the first saw blade positioning point 21 on the saw blade 2 for positioning, ensuring precise alignment between the saw blade and the fixing block.

[0023] Preferably, the saw blade fixing block 1 is provided with a set of locking screw holes 13, the connecting strip 3 is provided with a second set of locking screw holes 31, the saw blade locking screw group 23 passes through the first set of locking screw holes 13 and is screwed to the second set of locking screw holes 31, and the two saw blade locking screws of the saw blade locking screw group 23 are respectively provided on both sides of the saw blade 2.

[0024] Preferably, the connecting strip 3 is used to connect the saw blade fixing block 1 and the power unit of the electric drill, and also serves to clamp the saw blade. One end of the connecting strip 3 is provided with a second saw blade positioning hole 32, which is used to mate with the second saw blade positioning locking point 22 on the saw blade, thereby fixing the other end of the saw blade. The other end of the connecting strip 3 is connected to the power unit of the electric drill through the connecting screw hole group 33. This connection method allows power to be effectively transmitted to the saw blade, driving the saw blade to work.

[0025] Preferably, the connecting strip 3 is provided with a connecting screw hole group 33, the power unit is connected to the connecting screw hole group 33 through the connecting screw group 41, a washer group 42 is provided between the connecting screw group 41 and the connecting screw hole group 33, and a reciprocating impact block 5 is provided between the saw blade fixing block 1 and the washer group 42. The reciprocating impact block 5 will reciprocate between the saw blade fixing block 1 and the washer group 42 during operation.

[0026] The installation and implementation plan is as follows:

[0027] When installing the saw blade 2, firstly, its first saw blade positioning point 21 is inserted into the first saw blade positioning hole 12 of the saw blade fixing block 1, and then the second saw blade positioning point 22 is inserted into the second saw blade positioning hole 32 on the connecting strip 3. This positioning structure ensures that the saw blade will not shift during operation, thereby guaranteeing the straightness and stability of the cut.

[0028] The saw blade fixing block 1 and the connecting strip 3 are tightly connected by the saw blade locking screw group 23. The locking screw group 23 consists of two screws, which are screwed through the first set of locking screw holes 13 on the saw blade fixing block 1 and the second set of locking screw holes 31 on the connecting strip 3, respectively, to further ensure the stability of the saw blade during use.

[0029] The connecting bar 3 is connected to the power unit via the connecting screw assembly 41, transmitting the rotational power of the electric drill to the saw blade 2. A washer assembly 42 is provided between the connecting screw assembly 41 and the connecting screw hole assembly 33 to reduce friction and avoid unnecessary vibration. In this way, the connecting screw assembly 41 and the washer assembly 42 can effectively ensure the tightness of the connection and guarantee the stability of power transmission.

[0030] A reciprocating impact block 5 is provided between the saw blade fixing block 1 and the washer assembly 42. The reciprocating impact block 5 can generate reciprocating motion during operation, thereby enhancing the impact force and stability during the cutting process, further improving cutting efficiency, and reducing discomfort caused by vibration.

[0031] After the components of the electric drill-to-electric saw assembly are assembled, the power unit of the electric drill transmits power to the saw blade 2 via the connecting strip 3, causing the saw blade to begin reciprocating or rotating. The saw blade 2 is securely clamped in the appropriate position by the positioning holes and locking points on the saw blade fixing block 1 and the connecting strip 3, ensuring that the saw blade does not shift during operation. The impact force generated by the reciprocating impact block 5 improves cutting efficiency during operation, making the cutting smoother.

[0032] The positioning and clamping structure of the saw blade 2 within the saw blade fixing block 1 ensures its straightness and stability, avoiding the problems of unstable cutting and low precision caused by the unevenness of the saw blade 2 in existing technologies. Furthermore, the design of the entire clamping structure allows the saw blade to withstand greater working pressure and impact, thereby improving the service life of the equipment.

[0033] This invention improves the clamping structure of the saw blade 2, enabling it to maintain good straightness and stability during use. This avoids the operational inconvenience or inaccurate cutting caused by loosening or shifting of the saw blade 2 in existing technologies. Through a rational design, the drill-to-saw assembly provides sufficient power while reducing vibration during cutting, thus improving work efficiency. Furthermore, its compact structure and easy installation design give the drill-to-saw assembly excellent versatility and applicability, facilitating installation and maintenance for users.

[0034] In addition, the design of the reciprocating impact block 5 can generate effective impact force during operation, which helps to improve the cutting speed and effect. As a result, the electric drill to electric saw assembly not only has high stability, but also improves the cutting accuracy and efficiency during use.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
