Technical Field

[0001] The present application belongs to the technical field of wrenches, and in particular to a ratchet socket wrench. Background Art

[0002] A wrench is a common hand tool that mainly uses the principle of leverage to disassemble and assemble bolts, screws, nuts and other threaded fasteners. A ratchet wrench is a type of wrench. Based on its structural characteristics, the angle of use of the wrench can be easily adjusted. It is often used in narrow spaces such as motorcycles, water tanks, home appliances and other internal areas.

[0003] The existing Chinese patent with publication number CN111660237B discloses a multifunctional ratchet wrench, including a wrench head, a wrench handle, a ratchet rotatably arranged in a groove of the wrench head, and an adapter fixedly connected to the ratchet, a pair of latching swing arms are arranged in the groove of the wrench head, the fixed ends of the latching swing arms are hinged to the wrench head, and the movable ends are formed with pawls engaged with the ratchet, a switching piece is arranged between the latching swing arms, the switching piece is hinged to the wrench head, a movable connecting shaft is arranged inside the wrench handle, the connecting shaft is connected to the switching piece, and a structure for controlling the rotation of the connecting shaft is also arranged on the wrench handle.

[0004] The ratchet wrench can realize the switching of the wrench gears, but different sockets need to be replaced for bolts of different sizes. When using it, the work efficiency is often low because of the need to find the corresponding socket. Summary of the invention

[0005] The purpose of this application is to provide a ratchet socket wrench to address the above-mentioned technical problems, which can achieve rapid replacement of the socket so that it corresponds to the size of the fastener, eliminating the time of searching for the socket and improving work efficiency.

[0006] The present application provides a ratchet socket wrench, comprising:

[0007] Wrench body;

[0008] A socket seat, mounted on the wrench body;

[0009] A sleeve assembly is installed on the sleeve seat, wherein the sleeve assembly is provided with a plurality of sleeve members which are sleeved in sequence;

[0010] A telescopic assembly, used for controlling the extension of one of the sleeve members, wherein the telescopic assembly is mounted on the sleeve seat;

[0011] Wherein, the telescopic assembly includes a rotating seat and a first spring, the first spring is placed between the rotating seat and the sleeve seat, the rotating seat is provided with an abutment portion, the sleeve member is provided with an abutment groove adapted to the abutment portion, and a second spring is provided between the sleeve seat and the sleeve member.

[0012] The ratchet and pawl structures on the wrench body are used to rotate the sleeve seat, and the sleeve assembly is used to screw different fasteners. For fasteners of different sizes, the corresponding sleeve piece is selected to extend and cooperate with the fastener, and the seat is moved toward the wrench body and then rotated until the abutment on the rotating seat corresponds to the abutment groove on the corresponding sleeve piece. The rotating seat is released, and the abutment portion is matched with the abutment groove under the action of the first spring. At the same time, the sleeve piece is pushed outward by the elastic force of the first spring. When the abutment portion is separated from the abutment groove, the sleeve piece contracts and resets under the action of the second spring.

[0013] Furthermore, the rotating seat is provided with a rotating shaft, the rotating shaft has the same axis as the sleeve seat, the rotating shaft and the sleeve seat are movably connected, and the rotating shaft is placed on the abutment portion.

The rotating shaft and the abutment portion are rigidly connected, and the rotating shaft can move along its axial direction and circumferential direction.

[0015] Furthermore, the sleeve seat is provided with a groove, and the abutment portion is placed in the groove to move.

[0016] The abutment portion is placed in the groove for movement, and the groove includes a circumferential portion along the sleeve seat and an axial portion along the sleeve seat. The circumferential portion enables the rotating seat to rotate around the axis, and the axial portion enables the rotating seat to move along the axial direction, and the portions along the axial direction each correspond to an abutment groove on the sleeve member.

[0017] Furthermore, the sleeve member is provided with guide portions, and the guide portions are placed on both sides of the abutment groove.

[0018] The guiding part facilitates guiding the abutting part into the abutting groove, thereby improving the accuracy of the matching between the abutting part and the abutting groove.

[0019] Furthermore, the sleeve member is provided with a first flange, the first flange abuts against the second spring, and the sleeve seat is provided with a movable groove corresponding to the first flange.

[0020] The second spring abuts against the first flange, the outer edge of the first flange is circular, the abutment groove is arranged on the first flange of the corresponding sleeve member, and the first flange is movably connected to the movable groove to facilitate the extension and retraction of the sleeve seat.

[0021] Furthermore, the sleeve seat is provided with a magnet, and the axis of the magnet is the same as the axis of the sleeve seat.

[0022] The magnet produces a magnetic attraction on the screwed fastener, thereby improving the tightness of the connection between the fastener and the wrench during disassembly and assembly, making it difficult for the fastener to fall off the wrench.

[0023] Furthermore, the rotating seat is provided with a second flange, and the second flange is close to the wrench body;

[0024] When the rotating seat moves toward the wrench body, the second flange improves the convenience of moving the rotating seat toward the wrench body.

[0025] Furthermore, the rotating seat is provided with anti-skid patterns, and the anti-skid patterns are arranged on the outer wall surface of the rotating seat.

[0026] The anti-skid pattern is used to increase the friction when the rotating seat rotates, so that the rotation of the rotating seat is more stable. The anti-skid pattern adopts a mesh structure or a straight structure.

[0027] The beneficial effects of this application are:

[0028] 1. The sleeve assembly is used to screw different fasteners. For fasteners of different sizes, the corresponding sleeve is selected to extend and cooperate with the fastener.

[0029] 2. Move the rotating seat toward the wrench body, and then rotate it until the abutment portion on the rotating seat corresponds to the abutment groove on the corresponding sleeve member, release the rotating seat, and make the abutment portion cooperate with the abutment groove under the action of the first spring. At the same time, the sleeve member is pushed outward by the elastic force of the first spring.

[0030] 3. The guide portion facilitates guiding the abutting portion into the abutting groove, thereby improving the accuracy of the fit between the abutting portion and the abutting groove. BRIEF DESCRIPTION OF THE DRAWINGS
