Description

Rocking ratchet wrench with rotating grip

The present invention relates to the technical field of hand tools, in particular to a rocking ratchet wrench with a rotating grip.

Hand tools are driven by manpower and have the characteristics of convenience and lightness. They are indispensable in the operation. Their advantages are easy to carry, easy to operate and low cost. There are many types of hand tools, which can be roughly divided into sawing type, grinding type, impact type, rotating type, measuring type, lighting type and protection type according to their different processing types and characteristics.

In the technical field of hand tools, there is a rocking ratchet wrench, which is mainly composed of a handle and a working head pivotally connected to each other, in particular, the swing direction of the handle and the working head is pivotally connected to work The rotation direction of the head operation is perpendicular, so this kind of ratcheting ratchet wrench can not only be suitable for screw locking in the normal state, but when the locking position is narrow, or there is an obstacle on the swinging track of the wrench, the grip can be bent , So that the ratcheting ratchet wrench can be applied to different working occasions, and can also avoid obstacles to move smoothly.

It is worth mentioning that this type of ratcheting ratchet wrench is mostly used when the construction space is relatively zero. Although the ratchet can allow the user to remove the working head from the nut in the lock, but because the hand holds the ratchet ratchet When the handle of the wrench rotates, the angle of the ratcheting ratchet wrench changes, causing the user's wrist to bend to a less comfortable angle.

In view of this, it is indeed necessary to provide a new technical solution to improve the aforementioned defects.

The purpose of the present invention is to solve the problem of bending the user's wrist to an uneasy position when turning the ratcheting ratchet wrench.

To achieve the foregoing purpose, the present invention is a rocking ratchet wrench with a rotating grip, including:

A working head

A grip has a pivot piece pivotally connected to the working head, the pivot piece has a pivot rod, and a grip sleeve sleeved on the pivot rod, so that the grip sleeve can rotate relative to the pivot rod.

In a preferred embodiment, the grip sleeve is rod-shaped, and has two opposite end faces, one of which is concavely provided with a pivot hole, and the pivot hole is sleeved on the pivot rod.

In a preferred embodiment, an outer ring groove is recessed on the pivot rod along the circumferential direction, and the grip sleeve has an inner wall surface surrounding the pivot hole, and an inner ring groove is recessed on the inner wall surface There is also a gasket sleeved on the pivot rod, the gasket is sleeved in the outer ring groove, and the gasket slightly protrudes from the outer ring groove, when the pivot rod is inserted into the pivot hole The gasket protruding from the outer ring groove is locked in the inner ring groove.

In this way, when the user holds the grip sleeve and rotates it, the grip sleeve is grasped by the user's hand, and the grip sleeve and the pivoting member will relatively pivot between each other. Therefore, when the user pulls the rotary grip When the ratchet wrench is shaken, the grip sleeve will pivot relative to the pivoting member as the user pulls it to different angles, so that the grip sleeve follows the angle held by the user's wrist.

Please refer to FIG. 1 to FIG. 3, the present invention is a rocking ratchet wrench with a rotating grip, which is mainly composed of a working head 10 and a grip 20 pivotally connected to each other, in which:

The working head 10 is provided with a ratchet joint 11 so that the user can connect to the nut to be locked through the ratchet joint 11.

The handle 20 has a pivot member 21 pivotally connected to the working head 10, and a grip sleeve 22 sleeved on the pivot member 21, so that the grip sleeve 22 can rotate relative to the pivot rod 211.

In this embodiment, the pivoting member 21 has a pivot rod 211, the grip sleeve 22 is rod-shaped, and has opposite end surfaces, one end surface of which is recessed with a pivot hole 221, and the pivot hole 221 is sleeved in The pivot rod 211 enables the grip sleeve 22 to pivot relative to the pivoting member 21, and the grip sleeve 22 is provided for the user to hold, so that the user can directly hold the grip sleeve 22 and move the wrench .

More preferably, an outer ring groove 212 is circumferentially annularly recessed on the pivot rod 211, and the grip sleeve 22 has an inner wall surface 222 surrounding the pivot hole 221, and an annular recess is formed on the inner wall surface 222 The inner ring groove 223 further has a gasket 30 sleeved on the pivot rod 211. The gasket 30 is sleeved in the outer ring groove 212, and the gasket 30 slightly protrudes from the outer ring groove 212. When the pivot rod 211 is inserted into the pivot hole 221, the gasket 30 protruding from the outer ring groove 212 is locked in the inner ring groove 223, thereby preventing the pivot rod 211 from coming out of the pivot hole 221. The outer ring groove 212, the outer ring groove 212, and the gasket 30 are annular and surround the circumferential direction of the pivot rod 211 and the pivot hole 221, so the grip sleeve 22 can rotate along the circumferential direction.

The above is the structure configuration and connection relationship of the new model in a preferred embodiment. The use mode of the new model and the effects it can achieve are as follows:

Usually, the new type of ratcheting ratchet wrench with rotating grip is mostly used in the position where the construction space is at a zero, as shown in Figure 4, when the nut to be locked is located in a deep space and surrounded by a high wall surface, it can be bent The working head 10 makes an angle between the working head 10 and the grip 20, so that the working head 10 can be extended into the null space and combined with the nut to be locked.

When the user holds the grip sleeve 22 and rotates it, the grip sleeve 22 is gripped by the user's hand, and the grip sleeve 22 and the pivoting member 21 will relatively pivot between each other. When the ratcheting ratchet wrench of the grip is used, the grip sleeve 22 will pivot relative to the pivoting member 21 as the user pulls it to different angles, so that the grip sleeve 22 follows the angle held by the user's wrist.
