[0003] However, in some more restricted workspaces, it is difficult or even impossible to operate hidden screws and nuts with ordinary integrated wrenches. Utility Model Content

[0004] The utility model provides a swing-head wrench, which can fold the wrench head to change the angle between the wrench head and the plate body, thereby adapting to work in scenes with limited space.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions:

[0006] A movable swing head wrench includes a plate body and a wrench head. The upper end of the plate body is provided with a mounting groove, and the lower end of the wrench head is provided with a connecting block.

A tooth block is provided in the accommodating hole, and a first spring is provided at the lower end of the tooth block in the accommodating hole.

[0007] In the present invention, the wrench head can be rotated relative to the plate body to change the angle between the wrench head and the plate body. The stop section and the tooth block cooperate to limit the rotation of the wrench head relative to the plate body. When the staff uses it, the folding angle of the wrench head and the plate body can be quickly changed to adapt to the working space. At the same time, the stop section and the tooth block cooperate to stabilize the angle between the wrench head and the plate body.

[0008] The plate body is provided with protrusions on both sides of the installation groove, and the protrusions are provided with a first through hole; the connecting block is provided with a second through hole corresponding to the first through hole; the pin passes through the first through hole and the second through hole respectively.

[0009] In the utility model, the connecting block at the lower end of the spanner can be inserted into the mounting groove of the plate body, and the spanner is hinged to one end of the plate body through a pin.

[0010] The wrench head and the plate body can rotate around the pin.

[0011] In the present invention, the plate body and the spanner head cooperate with the first through hole, the second through hole and the pin, so that the spanner head can rotate around the pin, so that the spanner head and the plate body can change their folding angles.

[0012] Preferably, the stopping section is tooth-shaped.

[0013] Preferably, the upper end surface of the tooth block is engaged with the stopping section.

[0014] In the present invention, the upper end surface of the tooth block is engaged with the tooth-shaped stop section, so that the tooth block and the stop section are better matched to stabilize the angle between the wrench head and the plate body.

[0015] Preferably, both ends of the first spring respectively press against the lower end of the tooth block and the bottom of the accommodating hole, and the first spring is used to push the tooth block to engage with the connecting block to prevent the wrench from rotating relative to the plate body.

[0016] In the present invention, when the spanner is rotated, the tooth block is pushed downward by the raised portion of the toothed stop section, and at the same time the first spring is compressed, pushing the tooth block so that its upper end surface is in close contact with the surface of the stop section, so that when the spanner is rotated to a required angle, the spanner is not easily rotated relative to the plate body without the external force applied by the staff.

[0017] Preferably, the wrench head is a ratchet wrench. A wrench with a ratchet wrench allows the operator to continuously rotate the plate while working, without having to readjust the plate position during each rotation, thereby reducing labor intensity and being suitable for use in narrow workspaces.

[0018] Preferably, a ratchet ring is provided inside the wrench head, a retaining spring is provided on one edge of the ratchet ring inside the wrench head, and a brake block group is provided below the ratchet ring inside the wrench head.

[0019] In the utility model, the brake block group interacts with the ratchet, allowing the plate body to transmit torque when rotating in a set direction, but not transmitting torque when rotating in the opposite direction, thereby ensuring that the staff can maintain continuous rotation of the plate body during use, thereby improving efficiency.

[0020] Preferably, the brake block assembly includes a brake tooth block and a second spring, the upper surface of the brake tooth block is engaged with the outer surface of the ratchet ring; the two ends of the second spring are respectively pressed against the brake tooth block and the inside of the wrench.

[0021] In the utility model, the brake tooth block engages with the outer surface of the ratchet ring, so that when the plate body rotates in the set direction, the brake tooth block can push the ratchet ring to rotate, thereby realizing the operation of tightening or loosening the bolt or nut; the second spring can prevent the brake tooth block from pushing the ratchet ring to rotate when the plate body rotates in the opposite direction; and the second spring provides the necessary restoring force for the brake tooth block, so that it can quickly return to the initial position after release, ready for the next operation.

[0026] This embodiment 1 provides an adjustable swing head wrench, which includes a plate body 110 and a wrench head 130. The upper end of the plate body 110 is provided with a mounting groove 120, and the lower end of the wrench head 130 is provided with a connecting block 240. The connecting block 240 is hingedly arranged in the mounting groove 120 through a pin 260.

[0027] The bottom surface of the connecting block 240 is provided with a stop section 242 . The bottom surface of the mounting slot 120 is provided with an accommodating hole 252 . A tooth block 270 is provided in the accommodating hole 252 . A first spring 280 is provided at the lower end of the tooth block 270 in the accommodating hole 252 .

[0028] The wrench head 130 can be rotated relative to the plate body 110 to change the angle between the wrench head 130 and the plate body 110. The stop section 242 cooperates with the tooth block 270 to limit the rotation of the wrench head 130 relative to the plate body 110. When the staff uses it, they can quickly change the folding angle of the wrench head 130 and the plate body 110 to adapt to the work space. At the same time, the stop section 242 cooperates with the tooth block 270 to stabilize the angle between the wrench head 130 and the plate body 110.

[0029] In this embodiment, protrusions 250 are provided on both sides of the mounting groove 120 on the plate body 110, and a first through hole 241 is provided on the protrusion 250; a second through hole 251 is provided on the connecting block 240 corresponding to the first through hole 241; and the pin 260 passes through the first through hole 241 and the second through hole 251 respectively.

[0030] The connecting block 240 at the lower end of the wrench head 130 can be inserted into the mounting groove 120 of the plate body 110 , and the wrench head 130 is hinged to one end of the plate body 110 via a pin 260 .

[0031] In this embodiment, the wrench head 130 and the plate body 110 can rotate around the pin 260 .

[0032] The plate body 110 and the wrench head 130 cooperate with the first through hole 241 , the second through hole 251 and the pin 260 , so that the wrench head 130 can rotate around the pin 260 , so that the wrench head 130 and the plate body 110 can change their folding angles.

[0033] In this embodiment, the stopping section 242 is tooth-shaped, which is convenient to manufacture.

[0034] In this embodiment, the upper surface of the tooth block 270 engages with the stop section 242. The upper surface of the tooth block 270 engages with the toothed stop section 242, so that the tooth block 270 and the stop section 242 better cooperate to stabilize the angle between the wrench head 130 and the plate body 110.

[0035] In this embodiment, both ends of the first spring 280 respectively press against the lower end of the tooth block 270 and the bottom of the receiving hole 252 . The first spring 280 is used to push the tooth block 270 to engage with the connecting block 240 to prevent the wrench 130 from rotating relative to the plate 110 .

[0036] When the spanner 130 is rotated, the tooth block 270 is pushed downward by the raised portion of the toothed stop section 242, and at the same time the first spring 280 is compressed. The first spring 280 pushes the tooth block 270 so that its upper end surface is in close contact with the surface of the stop section 242, so that when the spanner 130 is rotated to a required angle, the spanner 130 is not easily rotated relative to the plate body 110 without the external force applied by the staff.

[0037] In this embodiment, the wrench head 130 is a ratchet wrench. A wrench with a ratchet wrench allows the operator to continuously rotate the plate body 110 while working, without having to readjust the position of the plate body 110 during each rotation, thereby reducing labor intensity and being suitable for use in narrow workspaces.
