Examples

With reference to fig. 1 to 4, the utility model discloses a multifunctional ratchet wrench, including handle 100, ratchet head 200 and pawl assembly 300, ratchet head 200 sets up in the front end of handle 100, and pawl assembly 300 sets up in handle 100 for locking ratchet head 200, handle 100 are provided with grafting portion 110 in the one end of keeping away from ratchet head 200, and grafting portion 110 is used for pegging graft with the pullover cooperation of any specification. The surface of the handle 100 is provided with an anti-slip sleeve 400, and the anti-slip sleeve 400 extends from the rear end of the handle 100 to the middle position thereof, so that the ratchet wrench is not easy to slip off when in use.

The rear end of the handle 100 is provided with an open-ended plug part 110, and the plug part 110 is used for being matched and plugged with a butt plug of any specification sleeve head. In this embodiment, at least two insertion parts 110 are disposed at the rear end of the handle 100, and the insertion parts 110 are disposed along the length direction of the handle 100.

As shown in fig. 2, 4 and 5, the front end of the handle 100 is provided with a downward mounting cavity 120, the ratchet head 200 and the pawl assembly 300 are disposed in the mounting cavity 120, the pawl assembly 300 includes a stop cam 310, a first stop member 320, a second stop member 330, a first compression spring 340 and a second compression spring 350, the stop cam 310 is rotatably disposed at one side of the ratchet head 200, the first stop member 320 and the second stop member 330 are respectively disposed at the left and right sides of the stop cam 310, and the stop cam 310 can respectively lock the ratchet head 200 from the left and right sides through the first stop member 320 and the second stop member 330. A first pressure spring 340 is arranged between the first stop piece 320 and the side wall of the mounting cavity 120, and a second pressure spring 350 is arranged between the second stop piece 330 and the side wall of the mounting cavity 120.

As shown in fig. 2 and 4 to 6, the mounting cavity 120 is provided with two mounting holes 130 at one side close to the handle 100, the first stopping member 320 and the second stopping member 330 both include a cylinder 361 and a stopping portion 362, the cylinder 361 is movably accommodated in the mounting hole 130, the cylinder 361 extends outward to form the stopping portion 362, a guide hole 363 is formed in a concave joint position of the cylinder 361 and the stopping portion 362, the stopping cam 310 rotates along the guide hole 363, when the ratchet wrench changes gears, the stopping portion 362 can accurately stop the ratchet head 200, and the ratchet wrench is more convenient to use.

The front end of the handle 100 is provided with a sealing plate 140, the sealing plate 140 is used for sealing the mounting cavity 120, the handle 100 is provided with a switch 150 on the other side of the sealing, and the switch 150 is connected with the stop cam 310 and is used for shifting the stop cam 310, so that the first stop piece 320 and the second stop piece 330 block the ratchet head 200, and the gear shifting of the ratchet wrench is realized.

The toggle switch 150 rotates the stop cam 310 to the right, the second stop member 330 retreats to one side of the mounting chamber 120 and compresses the second compression spring 350, at this time, the second stop member 330 unlocks the ratchet head 200, but the first stop member 320 still abuts against the ratchet head 200, at this time, the ratchet head 200 can only rotate clockwise relative to the mounting chamber 120, because when the ratchet head 200 rotates clockwise, the first stop member 320 can be driven by the ratchet head 200 to compress the first compression spring 340 and rotate clockwise due to the spring abutting between the first stop member 320 and the mounting chamber 120, and when the ratchet head 200 rotates counterclockwise, the first stop member 320 abuts against the ratchet head 200 so as not to rotate.

That is, when the ratchet wrench rotates clockwise, the ratchet head 200 and the nut connected thereto may rotate clockwise with respect to the mounting cavity 120 without rotating with the wrench, thereby realizing clockwise idling of the wrench; when the ratchet wrench is pulled counterclockwise, the ratchet head 200 and the nut connected thereto rotate counterclockwise along with the wrench due to the locking action of the first stopper 320, thereby tightening or loosening the nut.

Similarly, the toggle switch 150 can rotate the stop cam 310 to the left, that is, the ratchet wrench performs gear shifting, when the ratchet wrench rotates counterclockwise, the ratchet head 200 and the nut connected thereto can rotate clockwise relative to the mounting cavity 120 without rotating with the wrench, thereby realizing counterclockwise idling of the wrench; when the ratchet wrench is pulled clockwise, the ratchet head 200 and the nut connected thereto are rotated clockwise along with the wrench by the locking action of the second stopper 330, so that the nut is tightened.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
