Description

Technical Field

[0001] This utility model relates to the technical field of hardware tools, specifically to a portable folding screwdriver. Background Technology

[0002] Screwdrivers are designed to be flexible and foldable primarily to save storage space and make them easy to carry, while also meeting the needs of working in confined spaces. However, most bending screwdrivers can only bend to fixed angles, such as 90° or 180°, and the presence of the bending axis causes instability at the joint, making them prone to wobbling when force is applied. Although this meets the requirement of portability, it greatly reduces the strength required for use. Utility Model Content

[0003] This invention proposes a portable folding screwdriver that can achieve multi-angle rotation and positioning, ensuring the screwdriver's durability.

[0004] Therefore, the technical solution adopted is as follows: A portable folding screwdriver includes a handle, a working rod, and a connecting shaft rotatably connecting the two. Two ratchet wheels, Ratchet 1 and Ratchet 2, are coaxially mounted and fixed on the connecting shaft at intervals. The Ratchet 1 and Ratchet 2 have identical and corresponding outlines. The handle has a rotating groove for the working rod to rotate. The two side walls of the rotating groove form Support Wall 1 and Support Wall 2 of equal thickness. The two side walls of the working rod are respectively close to Support Wall 1 and Support Wall 2. The working rod, Support Wall 1, and Support Wall 2 all have toothed holes that match the Ratchet 1 and Ratchet 2. The two ends of the connecting shaft pass through support wall one and support wall two and are respectively fixed with a pressing part and a resetting part. A telescopic spring sleeved on the connecting shaft is connected between the pressing part and support wall one. The thickness of ratchet two is the same as the thickness of support wall two and equal to the interval between ratchet one and ratchet two. The thickness of ratchet one is the same as the thickness of the working rod and is greater than the thickness of ratchet two. When the pressing part abuts against support wall one, ratchet one is fully embedded in the tooth hole of the working rod. When the resetting part abuts against support wall two, ratchet two is fully embedded in the tooth hole of support wall two, and at this time the telescopic spring is in its natural state.

[0005] A further technical solution is that the first support wall and the second support wall are respectively provided with receiving grooves for accommodating the pressing part and the reset part.

[0006] A further technical solution is that the working rod includes a rod body and a rotating end, the rotating end rotating inside a rotating groove and being perpendicularly fixed to the rod body via a connecting rod. A further technical solution is that the working end of the rod is provided with a bit connection groove.

[0007] A further technical solution is that a pressing groove is provided on the outer side surface of the pressing part.

[0008] The working principle and beneficial effects of this application are as follows: When the screwdriver locks the working rod and handle, ratchet 1 and ratchet 2 respectively engage with support walls 1 and 2 on both sides, forming a double-sided lock. This ensures a more stable lock between the working rod and handle. At the same time, when the screwdriver is under stress, the stress is transmitted simultaneously through the symmetrical support walls 1 and 2, preventing unilateral force shifting or shaking. In addition, ratchet 1 and ratchet 2 can use their own teeth to ensure that the working rod is locked by ratchet 2 entering the tooth hole of support wall 2 for every tooth pitch of rotation. This achieves multi-angle fixation of the working rod and can cope with more operating environments. Attached Figure Description

Detailed Implementation

[0012] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0013] like Figures 1-6As shown in the illustration, this application embodiment demonstrates a portable folding screwdriver, the purpose of which is to solve the problems of folding screwdrivers not being able to lock at multiple angles and wobbling during use. A common screwdriver includes a handle 1, a working rod 2, and a connecting shaft 3 that rotatably connects the two. Based on this, this embodiment coaxially mounts and fixes ratchet wheel 1 31 and ratchet wheel 2 32 at intervals on the connecting shaft 3. The ratchet wheel 1 31 and ratchet wheel 2 32 have the same outline and correspond to each other, i.e., as shown in the illustration. Figure 5 As shown, ratchet 1 31 and ratchet 2 32 have the same parameters except for thickness, and their teeth are also corresponding to each other along the connecting shaft 3.

[0014] like Figure 2 As shown, a rotating groove 100 for the working rod 2 to rotate is provided on the handle 1. The two side walls of the rotating groove 100 form a support wall 101 and a support wall 102 of the same thickness. The two side walls of the working rod 2 are close to the support wall 101 and the support wall 102, respectively. The purpose of this close contact is to prevent the working rod 2 from wobbling left and right when working. Toothed holes 4 matching ratchet 31 and ratchet 32 ​​are provided on the working rod 2, the support wall 101, and the support wall 102, so that the connecting shaft 3 can drive the ratchet 31 and the ratchet 32 ​​to slide within the three toothed holes 4. Both ends of the connecting shaft 3 pass through support wall 101 and support wall 202 and are respectively fixed with pressing part 33 and reset part 34. A telescopic spring 35 sleeved on the connecting shaft 3 is connected between the pressing part 33 and support wall 101. During installation, the pressing part 33 and the connecting shaft 3 need to be fixed. Then, the telescopic spring 35 ratchet 1 31 and ratchet 2 32 are respectively sleeved on the connecting shaft 3 and fixed in the corresponding position. Next, the corresponding toothed hole 4 of the connecting shaft 3 is inserted into support wall 101 and support wall 202. Finally, the reset part 34 is fixed at the other end of the connecting shaft 3, and the installation is completed.

[0015] like Figures 3-4As shown, the thickness of ratchet 2 32 is the same as the thickness of support wall 2 102 and equal to the distance between ratchet 1 31 and ratchet 2 32. The thickness of ratchet 1 31 is the same as the thickness of working rod 2 and greater than the thickness of ratchet 2 32. When the pressing part 33 abuts against support wall 101, ratchet 1 31 is fully embedded in the toothed hole 4 of working rod 2. When the resetting part 34 abuts against support wall 2 102, ratchet 2 32 is fully embedded in the toothed hole 4 of support wall 2 102. At this time, the telescopic spring 35 is in its natural state. In this state, ratchet 2 32 is fully embedded in the toothed hole 4 of support wall 2 102. The working rod 2 and the toothed hole 4 of support wall 101 are simultaneously locked by ratchet 1 31, thus achieving the locking and fixing of working rod 2. To ensure it will not rotate further, when the pressing part 33 is pressed, the telescopic spring 35 is compressed, and the connecting shaft 3 drives the ratchet 2 32 to completely disengage from the toothed hole 4 of the support wall 2 102, and at the same time, it completely disengages from the toothed hole 4 of the support wall 1 101, and is fully embedded in the working rod 2. Thus, ratchet 1 31 and ratchet 2 32 are no longer connected to the handle 1. At this time, the working rod 2 can drive the connecting shaft 3 to rotate arbitrarily. When it rotates to the appropriate position, it ensures that ratchet 1 31 and ratchet 2 32 can correspond to the three toothed holes 4. When the pressing part 33 is released, the telescopic spring 35 drives ratchet 2 32 and ratchet 1 31 to re-engage into the support wall 2 102 and the support wall 1 101 respectively, restoring the locked state of the working rod 2. The handle 1 and the working rod 2 can no longer rotate relative to each other.

[0016] Based on this, the support wall 101 and the support wall 2 102 are respectively provided with receiving grooves 5 for accommodating the pressing part 33 and the reset part 34, ensuring the continuity of the overall screwdriver shape. In the natural locking state, the reset part 34 is embedded in the receiving groove 5 and will not protrude from the surface of the handle 1.

[0017] like Figure 5 As shown, the working lever 2 includes a lever body 21 and a rotating end 22. The rotating end 22 rotates inside the rotating groove 100 and is vertically fixed to the lever body 21 via a connecting rod 23. This allows the working lever 2 to be level with the handle 1 when folded and stored, ensuring efficient storage. Furthermore, the working end of the lever body 21 has a bit connecting groove 24 for easy replacement of different types of bits. Figure 1 As shown, a pressing groove (330) is provided on the outer side of the pressing part (33), which makes it convenient for the fingers to press on the pressing groove 330. This plays a role in positioning the axis of the connecting shaft 3, ensuring that the pressing position is the center position, and the pressing is smooth, while increasing the friction force during pressing.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
