Description

Technical Field

[0001] This utility model relates to a multifunctional lever handle, belonging to the technical field of furniture screw assembly tools. Background Technology

[0002] Currently, in the furniture manufacturing process, wooden boards are assembled together using screws. There are many types of screws available, and different screwdrivers are required for different screws. To improve the convenience of screw assembly, multiple screwdriver heads are usually provided, and a lever handle is used to adapt to multiple screwdriver heads for assembly.

[0003] Traditional lever handles have a relatively simple structure, only allowing vertical rotation after being assembled with the bolt cutter head. When screwing in screws that are difficult to turn, they cannot increase the torque of the lever handle, making it difficult to turn the screw and affecting the efficiency of screw assembly. Therefore, we have designed a multi-functional lever handle. Utility Model Content

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.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a multi-functional lever-assisted handle:

[0019] according to Figure 1-4 As shown, it includes a front sleeve 1, a threaded connecting sleeve 2, a connecting sleeve 3, a rotating component 4, and an internal hexagonal screwdriver bit 5. The internal hexagonal screwdriver bit 5 is fixedly installed inside the front sleeve 1. The top end of the front sleeve 1 is threadedly connected to the threaded connecting sleeve 2. The top end of the threaded connecting sleeve 2 is threadedly connected to the connecting sleeve 3. The internal part of the connecting sleeve 3 is nested with the adjustable angle rotating component 4.

[0020] Specifically, the lever handle has a simple structure and is easy to use. The front sleeve 1 has an internal hexagonal screwdriver bit 5 fixed inside, which can quickly replace screwdrivers of various shapes. The rotating part 4 of the lever handle can be pulled to the top of the connecting sleeve 3, and by rotating the angle, the torque of the lever handle can be increased, thus improving the efficiency of screw assembly.

[0021] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a multi-functional lever handle. The connecting sleeve 3 includes a sleeve body 301, an upper connecting end 302, and a lower connecting end 306. The sleeve body 301 has a through hole inside. The lower connecting end 306, which is integrally connected, is fixedly provided at the bottom end of the sleeve body 301. The lower connecting end 306 is threadedly connected to the threaded connecting sleeve 2. The upper connecting end 302 is fixedly provided at the top end of the sleeve body 301.

[0022] An arc-shaped groove 303 is provided in the middle of the upper connecting end 302. A ball groove 304 communicating with the through hole is provided at the center of the arc-shaped groove 303. Semi-circular grooves are provided on both sides of the top of the upper connecting end 302. A positioning hole 305 is provided at the center of each of the two semi-circular grooves.

[0023] Specifically, the positioning hole 305 facilitates the nesting and fixing of the strong magnetic post 405 set in the rotating component 4, so that the rotating component 4 and the connecting sleeve 3 can become one.

[0024] The surface of the connecting sleeve 3 is provided with splines distributed in a ring.

[0025] Specifically, the spline pattern on the surface of the connecting sleeve 3 increases the friction of the connecting sleeve 3.

[0026] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a multi-functional lever handle. The rotating component 4 includes a cylindrical end cap 401, a connecting rod 402, and a rotating ball part 403. The connecting rod 402 is provided at the center of the cylindrical end cap 401. The connecting rod 402 is inserted and connected to the through hole. The rotating ball part 403 is fixedly provided at the bottom end of the connecting rod 402.

The two strong magnetic columns 405 are nested and connected with the corresponding positioning holes 305.

[0028] Specifically, when the rotating component 4 is not rotating, the strong magnetic column 405 is nested with the positioning hole 305, which facilitates the fixing of the cylindrical end cap 401 and the connecting sleeve 3, making the rotating component 4 and the connecting sleeve 3 a single unit. When it is necessary to increase the torque, the rotating component 4 is pulled upward until the rotating ball part 403 moves into the inside of the ball groove 304. Then, the rotating component 4 is rotated along the direction of the arc groove 303, so that the rotating component 4 is perpendicular to the connecting sleeve 3, thereby increasing the torque of the lever handle.

[0029] Working principle: This utility model discloses a multi-functional lever handle. When using this lever handle, firstly, according to the requirements of the screw being assembled, the top of the screwdriver is inserted into the interior of the Allen head bit 5, and then the screw is rotated for assembly. During the screw rotation, in order to increase the torque of the lever handle, the rotating component 4 is manually pulled upward, causing the rotating ball part 403 at the end of the connecting rod 402 to move into the ball groove 304. Then, the rotating component 4 is manually rotated in the direction of the arc-shaped groove 303, rotating from a vertical state to a horizontal state, and placing the connecting rod 402 in the arc-shaped groove 303. Finally, the rotating component 4 is manually pushed horizontally to complete the screw assembly, increasing the torque of the lever handle and improving the efficiency of screw assembly.
