[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Reference Figure 1-11A full-function quick-release ratchet assembly includes a ratchet shaft 1, a mounting base 2 fixedly connected to the outer side of the ratchet shaft 1, a cavity 3 reserved on the outer side of the mounting base 2, a first spring 4 and a toothed plate 5 disposed inside the cavity 3, a retaining groove 6 and a sliding groove 8 reserved on the outer side of the ratchet shaft 1, a retaining ring 7 engaged inside the retaining groove 6, a first stainless steel ball 9 installed inside the sliding groove 8, a ratchet seat 10 disposed on the outer side of the ratchet shaft 1, a fixing groove 11 opened inside the ratchet seat 10, ratchet teeth 12 disposed inside the ratchet seat 10, a mounting groove 13 opened on the outer side of the ratchet seat 10, a slot 15 reserved inside the ratchet seat 10, a third stainless steel ball 18 installed inside the mounting groove 13, a fourth spring 19 installed inside the slot 15, a lock head 20 and a pull ring 21 sleeved on the outer side of the ratchet seat 10, and the outer side of the ratchet seat 10... A third spring 14 is sleeved inside the pull ring 21. A circular groove 22 is reserved on the outer side of the pull ring 21. The mounting groove 13, the third stainless steel ball 18, and the circular groove 22 are distributed in a ring at equal intervals. The third stainless steel ball 18 and the circular groove 22 are engaged. The inner side of the pull ring 21 is in contact with one end of the third spring 14. One end of the inner side of the locking head 20 is in contact with one end of the outer side of the pull ring 21. This facilitates the installation and use of hardware tools, making the overall structure more stable after installation and easy to disassemble later. The cooperation between the toothed plate 5 and the ratchet 12 makes the tool easier and more convenient to use. The installed bit can be engaged by the third stainless steel ball 18. At the same time, the position of the third stainless steel ball 18 can be controlled by manually pulling the pull ring 21. The bit can be replaced at any time, which is convenient for operation.

[0034] like Figure 1-11As shown, a left and right rotary dial 16 is provided on the outer side of the mounting base 2. A limit groove 161 is reserved on the outer side of the left and right rotary dial 16. A mounting hole 162 is opened inside the left and right rotary dial 16. A second spring 163 is installed inside the mounting hole 162. A second stainless steel ball 164 is provided on the outer side of the second spring 163. A fixing ring 165 is fixedly connected to the inner side of the left and right rotary dial 16. An adjusting block 166 is fixedly connected to the outer side of the fixing ring 165. A reference plate 17 is sleeved on the outer side of the ratchet shaft 1. An adjusting hole 171 is opened inside the reference plate 17. The internal fixed connection of 7 is limited by a limiting block 172. Multiple sets of cavities 3, first springs 4, and toothed plates 5 are arranged in a ring. Each set has multiple first springs 4. The toothed plates 5 are engaged inside the cavity 3 and slidably connected to it. The toothed plates 5 and the mounting base 2 are movably connected via the first springs 4. Multiple ratchet teeth 12 are evenly spaced in a ring, and the toothed plates 5 and ratchet teeth 12 are meshed together. One end of the ratchet shaft 1 near the slide groove 8 is inserted into the fixed groove 11. The outer side of the first stainless steel ball 9 contacts the inner side of the fixed groove 11. The first stainless steel ball 9 and the slide groove 8 slide together. The rotating dial 16 passes through the ratchet shaft 1 and is sleeved on the outside of the mounting base 2. One side of the outer side of the reference plate 17 is in contact with the outer side of the retaining ring 7. Adjusting holes 171, limiting blocks 172, limiting grooves 161, mounting holes 162, second springs 163, second stainless steel balls 164, and adjusting blocks 166 are arranged in four groups at equal intervals in a ring. Each group of adjusting holes 171 has three holes. The limiting blocks 172 are engaged inside the limiting grooves 161 and are slidably connected to them. The second stainless steel balls 164 are engaged with the adjusting holes 171. Both ends of the outer side of the segment 166 are in contact with the toothed plate 5. It can be adjusted and controlled by rotating the left and right dial 16. When the left and right dial 16 is in the middle of the reference plate 17, the ratchet 12 and the toothed plate 5 cannot mesh and transmit power, so the structure is locked. When the left and right dial 16 rotates to the left or right, the second stainless steel ball 164 is located inside another adjustment hole 171. At this time, the adjustment block 166 no longer restricts the toothed plate 5, and the device can be used to rotate to the left or to the right, which is more convenient to control.

[0035] The implementation principle of this embodiment is as follows: When in use, the bit that is used with the device is installed into the slot 15 inside the ratchet seat 10. At this time, the outer side of the bit is locked and fixed by the third stainless steel ball 18. After that, when the device is in use, the left and right rotary dial 16 can be rotated to the middle of the base plate 17. At this time, the second stainless steel ball 164 is located at the adjustment hole 171 in the middle position. At this time, the adjustment block 166 restricts each tooth 5, so that the tooth 5 cannot mesh with the next set of ratchet teeth 12, so that the device cannot be rotated.

[0036] When the left and right rotary dial 16 is rotated to the left of the reference dial 17, the second stainless steel ball 164 engages with the adjustment hole 171 located on the left, causing the adjustment block 166 to rotate to the left as well. This forces the toothed piece 5 located on the left, which is in contact with the adjustment block 166, into the cavity 3. This part of the toothed piece 5 does not engage with the ratchet 12, but the toothed piece 5 on the right engages with the ratchet 12 normally, allowing the bit to be rotated to the right for adjustment.

[0037] When the left and right rotary dial 16 is rotated to the right of the reference dial 17, the second stainless steel ball 164 engages with the adjustment hole 171 located on the right side, causing the adjustment block 166 to rotate to the right as well. This forces the toothed piece 5 located on the right side, which is in contact with the adjustment block 166, into the cavity 3. This part of the toothed piece 5 does not engage with the ratchet 12, but the toothed piece 5 on the left side engages with the ratchet 12 normally, allowing the bit to be rotated to the left side for adjustment.

[0038] The device can accommodate different types of screwdriver bits. By manually pulling the pull ring 21, the pull ring 21 can control the movement of the third stainless steel ball 18. The third stainless steel ball 18 controls the engagement with the outside of the screwdriver bit, while the screwdriver bit contacts the internal fourth spring 19. The fourth spring 19 quickly ejects the screwdriver bit from the device, enabling quick disassembly and replacement with another screwdriver bit. It can also quickly install screwdriver bits and can be rotated and adjusted in different directions according to actual usage needs, meeting various usage requirements and making it more convenient and faster to use.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
