Description

Technical Field

[0001] This utility model relates to a wrench, and more particularly to a portable integrated ratchet wrench. Background Technology

[0002] A ratchet wrench is a multi-functional and efficient bolt tightening and loosening tool. When the handle is turned in one direction, the pawl engages with the ratchet, causing the ratchet to rotate and thus driving the bolt or nut to turn. When the handle is turned in the opposite direction, the pawl slides on the back of the ratchet teeth, and the ratchet does not rotate, achieving unidirectional transmission. This facilitates operation in confined spaces and improves work efficiency. It plays an important role in various industrial and daily life applications. Its unique design and working mechanism make it increasingly widely used in machinery maintenance, assembly, and repair.

[0003] Conventional ratchet wrenches are usually equipped with a variety of different sizes of bits to accommodate bolts of various sizes. The number of bits is large, and they are stored in a storage box. However, the placement, retrieval, and carrying of the storage box are inconvenient, and there is still room for improvement in its integration. Utility Model Content

[0004] This invention provides a portable integrated ratchet wrench to overcome the shortcomings of existing ratchet wrenches, such as insufficient integration of bits and poor portability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a portable integrated ratchet wrench, including a handle assembly. A ratchet head is nested in the upper part of the handle assembly, and a bit is engaged in the lower cavity. The handle assembly includes a handle, and the inner surface of the handle has several hexagonal holes and magnet slots along the horizontal direction. The hexagonal holes are used to engage the bit, and the magnet slots are used to install magnets. The magnets are used to attract the tail of the bit. A magnet cover plate is locked and fixed to the outside of the handle by magnet cover plate fixing screws to cover the magnet and prevent it from falling off.

[0007] Furthermore, the upper part of the handle is provided with a ratchet head fixing groove for nesting a ratchet head, and the ratchet head is fixed to the handle by a ratchet head fixing screw. The lower part is also provided with a hexagonal hole for engaging the bit, and a magnet is also provided in the hexagonal hole.

[0008] Furthermore, the ratchet head includes a housing, the upper part of which has a through hole for installing a ratchet hexagonal sleeve, and the middle part has a through hole for installing a reversing knob. A retaining spring is engaged at the lower end of the ratchet hexagonal sleeve.

[0009] Furthermore, a groove is provided in the middle of the outer diameter of the bit, and the groove is restricted by a retaining spring to prevent the bit from becoming loose.

[0010] Furthermore, the hexagonal hole and the magnet slot are arranged on the same horizontal line.

[0011] Furthermore, rotating the reversing knob is used to switch the ratchet between forward and reverse rotation.

[0012] The beneficial effects achieved by this utility model are as follows: it integrates the bit storage function and the ratchet wrench handle into one unit, uses magnets to attract the bits, and allows for direct access to or placement of the bits from the side of the handle. Furthermore, it features a double-ended bit design, reducing the number of bits required while accommodating a wider range of specifications. The bottom has hexagonal holes and magnets for bit installation, realizing the dual function of a ratchet wrench and a screwdriver. This ratchet wrench is portable, highly integrated, and allows for quicker bit placement and retrieval, making it ideal for daily use, especially for outdoor activities. Attached Figure Description
