Detailed ways

As shown in Figures 1, 2, and 3, the detachable adjustable wrench includes a wrench head 1 and a handle 2. The upper end of the wrench head 1 is provided with a slot 11. The special feature of this wrench is that its wrench head 1 is provided with multiple, The lower end of each wrench head 1 is provided with a connecting portion 12 . In the figure, only one wrench head is drawn as an illustration. Other wrench heads have different slot specifications, and the rest are the same, so there is no need to draw them one by one.

The connecting part 12 of the wrench head is flat, and the left and right sides of the connecting part 12 are planes, and the distance between the left side and the right side of the connecting part 12 gradually decreases along the direction from top to bottom, so that the connecting part 12 form a tapered plate shape. A concave positioning hole 13 is respectively provided on the left side and the right side of the connecting portion 12 .

The handle 2 is provided with one, and the upper end of the handle 2 is provided with a connection part insertion hole 21 adapted to the shape of the connection part 12 . The left and right sides of the connecting part insertion hole 21 respectively have a clamping ball 23 for cooperating with the positioning hole 13. The clamping ball 23 is connected to one end of a spring 24 that expands and contracts in the left and right directions. In the guide hole 25 and the other end of the spring 24 is fixedly connected with the handle 2 in the guide hole.

In the detachable adjustable wrench, further: on the wrench head 1 , the positions of the positioning holes 13 provided on the left side and the right side of the connecting part 12 are symmetrical to each other. In this way, when the wrench head is loaded into the insertion hole 21 of the connecting part, the two clamping balls 23 are synchronously clamped into the respective corresponding positioning holes 13 to achieve simultaneous clamping, better stability after connection, and easy assembly and disassembly.

In addition, in the wrench, further: the positioning hole 13 of the wrench head is arranged on the upper part of the connecting part 12, so that the wrench head can avoid the problem of shaking during the use of the wrench.

In the detachable adjustable wrench, the lower ends of the left side and the right side of the connecting part 12 are connected by an arc surface 14 . The bottom inner wall of the corresponding positioning hole 13 is also a circular arc surface. After such a structure is assembled together, it is not easy to shake, and it is beneficial to the positioning of the wrench head.

When in use, select a wrench head of appropriate specifications, and forcefully snap the connection part 12 of the wrench head 1 into the connection part insertion hole 21 of the handle 2, and the spring 24 will prompt the clamping ball 23 to enter the positioning hole 13, and the wrench head The connecting part 12 of 1 is closely matched with the inner surface of the connecting part insertion hole 21 of the handle, especially the front and rear surfaces, and the springs 24 on both sides will hold the clamping ball 23 against the positioning hole 13 to lock the wrench Head 1, so that the connection between wrench head 1 and handle 2 is reliable.

When the wrench head needs to be replaced or removed, the wrench head can be pulled directly upwards to remove it.

The positioning hole 13 in this embodiment is also set in a semi-spherical shape, which is beneficial to closely cooperate with the clamping ball, and at the same time makes the assembly and disassembly operation easy and will not cause the jamming phenomenon.

In addition, when the connecting part 12 is inserted into the connecting part insertion hole 21, the clamping ball can be smoothly ejected into the positioning hole 13, and a guide groove or a guide bar can be provided on the front side and/or the rear side of the connecting part. Guide strips or guide grooves are set at the corresponding positions in the insertion hole 21 of the connecting part. As shown in Figure 4, the guide strips 15 and the guide grooves 26 cooperate with each other to play a guiding role, so as to ensure that the clamping ball 23 is smooth. Pop into the positioning hole 13.

The detachable adjustable wrench also includes a booster handle 3 , and one end of the booster handle 3 is connected to a section of threaded post 31 . A threaded hole 22 is arranged at the lower end of the handle 2, and the axis of the threaded hole 22 is arranged along the front-rear direction, and the threaded hole 22 cooperates with the threaded column 31 on the booster handle.

When installing a bolt with a larger thread diameter, a larger rotational torque is required, and a booster handle 3 can be installed on the handle 2, and the staff can hold the booster handle 3 to rotate to assemble and disassemble the bolt connection.

The connection between the booster handle 3 and the handle 2 is not limited to threaded connection, and other mechanical connection methods can also be used instead, but they all belong to the equivalent replacement of threaded connection.

"Up", "Down", "Left", "Right", "Front" and "Rear" in the utility model are all relative positions adopted for the convenience of describing the structure and positional relationship, and cannot be understood as absolute positions to constitute a reference to the present invention. Limitations on the scope of protection of utility models.
