Description

A multifunctional screwdriver head mechanism

technical field

The utility model relates to a multifunctional screwdriver head mechanism.

Background technique

At present, in the assembly process of assembling automobile systems, there are various types of screws used for different positions, and a multifunctional screwdriver head mechanism is needed to facilitate use and improve work efficiency. However, most of the existing screwdrivers are ordinary wooden handles with integrated cutter heads, or single screwdrivers with replaceable different types of cutter heads, and the above types are not high in limit alignment when loosening or locking screws. There are problems of low efficiency and poor applicability.

Utility model content

The utility model provides a multifunctional screwdriver head mechanism in order to solve the problem of poor alignment of the existing screwdriver when the screw is loosened or locked.

A multifunctional screwdriver head mechanism, comprising a left working cutter head, a right working cutter head, a cutter head connecting rod, a handle, a first jacking wire and a second jacking wire; the left end of the right working cutter head is connected to the The left end is welded as an integral structure, and a U-shaped groove is arranged on the connecting rod of the cutter head, and the right end of the connecting rod of the cutter head is threadedly connected with the nut; the connecting rod of the cutter head is inserted into the handle and on the connecting rod of the cutter head between the nut and the handle The spring is installed; the inner side wall of the handle is provided with a first top wire and a second top wire, and the first top wire is inserted into the U-shaped groove of the connecting rod of the cutter head; the right end of the left working cutter head is provided with an anti-rotation The hole structure, the left working cutter head is inserted into the handle and tightened with the left end of the right working cutter head through the hole structure, and the second jacking wire and the handle side wall are threaded to tighten the left working cutter head.

Beneficial effects of the utility model: the utility model solves the problem of low limit alignment of the screwdriver in the prior art when loosening or locking the screw, adopts a spring structure, and the left working cutter head is installed in the non-use state , the anti-rotation hole at the right end of the left cutter head and the right end are in a state of being far away from each other. Only when the cutter head is working under force, the left working cutter head is pressed inward due to the force and the spring is compressed. At this time, the left cutter The anti-rotation hole at the right end of the head is in a tight state with the right end, which improves the accuracy of the limit, and at the same time protects the risk of head-on damage to the cutter heads on both sides. The new cutter head mechanism has strong applicability, reduces labor intensity, and improves work efficiency. efficiency.

The multifunctional screwdriver head mechanism described in the utility model can realize random replacement of the cutter head and complete the screw tightening process accurately and quickly.

Detailed ways

Specific Embodiments 1. This embodiment is described in conjunction with FIGS. 1 to 3. A multifunctional screwdriver head mechanism includes a left working cutter head 1, a right working cutter head 2, a cutter head connecting rod 3, a handle 4, and a first screwdriver. 5 and the second top wire 6; the left end of the right working cutter head 2 and the left end of the cutter head connecting rod 3 are welded as one structure, the U-shaped groove is set on the cutter head connecting rod 3, and the right end of the cutter head connecting rod 3 Threaded connection with nut 7;

The cutter head connecting rod 3 is inserted into the handle 4, and a spring 8 is installed on the cutter head connecting rod 3 between the nut 7 and the handle 4, so that the cutter head connecting rod 3 can have telescopic activities in the handle 4;

The inner side wall of the handle 4 is provided with a first top wire 5 and a second top wire 6, and the first top wire 5 is inserted into the U-shaped groove 9 of the connecting rod of the cutter head; preventing the connecting rod of the cutter head from being drawn out of the handle fall off;

The right end of the left working cutter head 1 is provided with an anti-rotation hole structure, the left working cutter head 1 is inserted into the handle 4, and the protruding part at the welding point of the left end of the hole structure and the right working cutter head 2 is tightened, the second Two jacking wires 6 and handle 4 sidewall thread top tight left working cutter head 1.

In this embodiment, the operation structure is simplified by improving the mechanism of the working cutter head. Through the observation of the screw tightening process completed by the connection of the cutter head mechanism to the muzzle, the accuracy and stability of the automatic loosening screw operation are basically realized. The project is simple in structure, light in weight and high in practicability.

The mechanism described in this embodiment is based on a structural handle with both sides of which can be freely replaced with cutter heads. The two sides can be easily disassembled and replaced with different types of cutter heads, thereby realizing quick replacement of cutter heads. Wide range of applications.
