Description

A multifunctional screwdriver ratchet handle

technical field

The invention relates to a multifunctional screwdriver ratchet handle, in particular to a multi-functional screwdriver ratchet handle which can be used as both a screwdriver handle and a socket wrench handle with 360° rotatable multi-heads.

Background technique

Screws and bolts are very commonly used fasteners. According to international practice or national standards, usually the head of the screw adopts a concave in-line, cross, five-star, plum blossom and other screwing forms, and the head of the bolt adopts an outer shape. Convex hexagonal head or concave hexagonal pit and other screwing forms; therefore, people have configured various screwdrivers (commonly known as screwdrivers) and wrenches. Due to the variety of specifications, in order to be easy to carry, the single-head screwdriver has developed into a screwdriver handle with a replaceable bit head, and the wrench has developed into a socket wrench with a variable diameter. Then a ratchet handle and a ratchet wrench appeared, and the operator only needed to do repeated actions to tighten the fasteners; in order to adapt to the limited space, a screwdriver handle and sleeve that could be adjusted at a certain angle and could also replace the bit appeared. barrel wrench. However, there are still some deficiencies in the current technology:

1. The connection form is single. The handle of the ratchet screwdriver is connected to the screwdriver head in the form of a hexagonal hole, and the handle of the ratchet sleeve is connected to the sleeve in the form of a square tenon.

2. The purpose of the tool is single. The existing screwdriver cannot be used as a wrench. Similarly, the wrench cannot be used as a screwdriver. No matter which of the above tools, it needs to be worn at the same time to adapt to the commonly used bit and socket. First, it is troublesome to change tools during operation; second, screw handles and socket wrenches take up a lot of tool kit.

3. The angle of rotation is limited. Although the ratchet screwdriver handle of the prior art can be adjusted to a certain angle, the adjusted angle does not exceed 90°.

Contents of the invention

The purpose of the present invention is to provide a multifunctional screwdriver ratchet handle, that is, to provide a multi-functional screwdriver ratchet handle that can be used as a screwdriver handle and a socket wrench handle with multiple heads that can be rotated by 360° . A multifunctional screwdriver ratchet handle of the present invention combines the ratchet screwdriver and ratchet socket wrench of the prior art into one, and integrates multi-standard screwdriver joints into one body, which makes up for the single connection form of the prior art. The method is single, the adjustment angle is limited, and it is inconvenient to use and carry.

A ratchet handle of a multifunctional screwdriver of the present invention comprises a ratchet part, a handle body and a handshake part, and the rear end of the handle is fixed with a handshake part. The central axis of rotation intersects the central axis of the handle perpendicularly, and several screwdriver joints are radially distributed on the outer edge of the ratchet part. The central axis of the screwdriver joint and the central axis of the handle are in the same plane; There is a clamping device in between; the clamping device includes a clamping sleeve, a spring rod, a clamping spring and a handle. The handle body is hollow and has a "Z" shaped groove. The sleeve is located in the handle body and is set on the front end of the spring rod. The outside of the clamp sleeve is fixed with a handle. The handle can slide in the "Z" shaped groove of the handle body. The spring rod is fixedly connected with the handle body. The snap spring Mounted on a spring rod and placed behind snap sleeves.

As a preferred technical solution:

The multifunctional screwdriver ratchet handle as described above, wherein the several screwdriver joints are uniformly distributed on the outer edge of the ratchet part at equal angles. Uniform distribution of equal angles is beautiful, and at the same time it is convenient for the positioning of the screw joint. The angle is usually 120°, 90° or 60°, and the distribution of the screw joints is three-point, four-point and six-point symmetrical distribution.

The clamping device is easy to operate and firm in clamping position, and is suitable for a structure in which even pairs of screwdriver joints are symmetrically distributed on the outer edge of the ratchet part. The locking device can also be in the form of positioning between the front end of the handle body and the ratchet part through a movable pin shaft, or in the form of cooperation between a movable sphere with a spring and a hemispherical pit.

As shown in Figure 2, there is a ratchet mechanism in the ratchet part 1, including a rotating ratchet sleeve 1.1, a ratchet 1.5, a ratchet cover 1.4, a ratchet spring 1.3, a double-headed ratchet shaft 1.2 and a snap ring 1.6. The two ends of the head ratchet shaft 1.2 are screwdriver joints 1.7 of different specifications. Here, a double-headed ratchet shaft is applied, and a ratchet device can output double heads, and the ratchet device can be turned left or right for reversing. Also can be to use single head ratchet shaft or multi-head ratchet shaft.

The front end of the handle body 2 is split in a "Y" shape, as shown in Figure 6, the head of the "Y"-shaped legs corresponds to the opening, the ratchet part is located in the middle of the "Y"-shaped legs, and the two ends of the central axis of the ratchet part are respectively Fits with the holes in the head of the "Y" shaped bipod. The tool with this structure is the most compact, the transmission torque is the largest, and the form of symmetrical distribution is used, which is relatively coordinated.

The handshake part 3 has a handle sheath, and the sheath is sheathed at the rear end of the handle. The outside of the handshake part can be a plastic or wooden sheath.
