[0002] Machining power tools are a type of tool widely used in the machining process. They are driven by electricity to perform various machining operations, and the electric drill is a commonly used power tool in machining. It mainly converts electrical energy into mechanical energy and drives the drill bit to rotate at high speed through an electric motor, thereby achieving the function of drilling.

[0003] When a traditional electric drill is in operation, the drill bit often becomes loose due to various factors. For example, during continuous high-intensity drilling operations, vibration and impact may cause the connection between the drill bit and the chuck to gradually loosen; or when the rotation direction is frequently switched, the drill bit is also prone to loosening. In addition, the chuck design of some electric drills may be defective and cannot effectively tighten the drill bit, and it is also prone to loosening over time during use.

[0027] The movable block 51 is rotatably connected to the inside of the torsion block 2, a fixed rod 52 is fixedly installed inside the movable block 51, a sliding rod 53 is slidably connected inside the fixed rod 52, a fixed spring 54 is fixedly installed on the surface of the sliding rod 53, the fixed spring 54 is fixedly installed on the top of the fixed rod 52, a slip ring 55 is slidably connected to the surface of the fixed rod 52, the slip ring 55 is fixedly installed on the surface of the sliding rod 53, a connecting plate 56 is hinged on the top of the slip ring 55, a resistance plate 57 is hinged on the outside of the connecting plate 56, the resistance plate 57 is hinged to the surface of the fixed rod 52, a positioning rod 58 is fixedly installed on the top of the resistance plate 57, and a positioning ring 59 is installed on the surface of the drill bit 3, which increases the stability of the drill bit 3 when in use and prevents the drill bit 3 from loosening and causing the risk of falling.

[0028] The fixing assembly 4 includes: a fixing plate 41, the fixing plate 41 is fixedly mounted inside the torsion block 2, a turntable 42 is rotatably connected inside the fixing plate 41, the turntable 42 is fixedly mounted on the top of the movable block 51, a connecting strip 43 is fixedly mounted on the surface of the turntable 42, one end of a clamping block 44 is slidably connected inside the connecting strip 43, and the other end of the clamping block 44 is slidably connected to the top of the turntable 42. When the drill bit 3 is connected to the electric drill 1, the turntable 42 can be driven to rotate by manually rotating the movable block 51. When the turntable 42 rotates, the clamping block 44 is driven to move on the surface of the turntable 42 toward the center point of the turntable 42. When the clamping block 44 moves, It will be stuck in the groove 30 opened on the surface of the drill bit 3, thereby improving the convenience of connecting the drill bit 3 with the electric drill 1 and accelerating the efficiency of replacing the drill bit 3. The groove 30 is opened on the surface of the drill bit 3, which can enhance the stability of the connection between the drill bit 3 and the electric drill 1. The cross section of the resistance plate 57 is T-shaped, which can improve the resistance effect of the resistance plate 57. The surface of the turntable 42 is provided with a slide groove 1 420, which can drive the clamping block 44 to slide on the surface of the turntable 42.

[0029] When the electric drill 1 is in use, it is usually composed of a motor, a gear transmission mechanism, a drill chuck, a drill bit 3, etc. When the power is turned on, the motor starts to operate, generating rotational power through internal electromagnetic induction. The rotational motion of the motor is decelerated and the torque is increased through the gear transmission mechanism, converting the high-speed and low-torque rotation into a low-speed and high-torque rotation to meet the needs of drilling operations. When the drill bit 3 is inserted into the inside of the torsion block 2, the drill bit 3 will abut against the top of the slide rod 53 and drive the slide rod 53 to slide downward. When the connection between the drill bit 3 and the electric drill 1 becomes loose due to the long-term pressure on the drill bit 3, the drill bit 3 will move away from the surface of the electric drill 1. When the drill bit 3 moves, the abutment of the drill bit 3 against the slide rod 53 will be released, and the slide rod 53 will reset under the action of the fixed spring 54. When the slide rod 53 resets, it will drive the slip ring 55 to slide upward. When the slip ring 55 slides upward, it will drive the connecting plate 56 to move away from the surface of the fixed rod 52. When the connecting plate 56 moves, it will drive the abutting plate 57 to move in the sliding direction of the connecting plate 56, so as to abut against the inner wall of the torsion block 2. When the abutting plate 57 moves upward, it will also drive the positioning rod 58 to move upward, so as to be inserted into the inside of the positioning ring 59, increasing the stability of the drill bit 3 during use and preventing the drill bit 3 from loosening and falling off.

[0030] When the drill bit 3 is connected to the electric drill 1, the rotating block 51 can be manually rotated to drive the rotation of the turntable 42. When the turntable 42 rotates, it will drive the clamping block 44 to move towards the center point of the turntable 42 on the surface of the turntable 42. When the clamping block 44 moves, it will be clamped in the card slot 30 opened on the surface of the drill bit 3, thus improving the convenience of the connection between the drill bit 3 and the electric drill 1 and accelerating the replacement efficiency of the drill bit 3.

[0031] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are all within the protection scope of the present utility model.
