Description

Technical Field

[0001] This utility model mainly relates to the field of electric screwdriver technology, specifically to a portable, retractable electric screwdriver. Background Technology

[0002] In everyday repair, assembly, and handicraft work, the electric screwdriver is a commonly used tool. Traditional electric screwdrivers typically consist of a separate screwdriver body and a single handle. This design makes them bulky when not in use, inconvenient to store and carry. This is especially true for repair personnel or craft enthusiasts who frequently move between different work locations; the large size and inconvenience of carrying them limit their ease of use.

[0003] Furthermore, traditional electric screwdrivers have a relatively simple connection between the screwdriver body and the handle, essentially a single integrated design, making it difficult to achieve flexible rotation and precise positioning of the screwdriver body relative to the handle. This can affect work efficiency and accuracy in scenarios requiring delicate operation or multi-angle work, such as in electronic equipment repair, where tightening or loosening screws in confined spaces requires the electric screwdriver to be able to flexibly adjust angles and maintain stability.

[0004] As people's demands for the portability and multifunctionality of tools continue to increase, the existing electric screwdriver structure can no longer meet the needs. Developing a portable electric screwdriver that can effectively solve the problems of inconvenient storage and flexible use has become a trend in the industry. Utility Model Content

[0034] See attached document Figures 1-8 A portable, retractable electric screwdriver includes an electric screwdriver body 1 and a retractable handle 2. The head of the electric screwdriver body 1 is used to install a screwdriver bit 5, and its tail is rotatably mounted on the retractable handle 2. The retractable handle 2 includes a first handle splice 21 and a second handle splice 22 that are detachably connected. The first handle splice 21 has a first storage compartment 24, and the second handle splice 22 has a second storage compartment 25. When the first handle splice 21 and the second handle splice 22 are combined, the first storage compartment 24 and the second handle splice 22 are retractable. The second storage compartment 25 forms the storage compartment for the electric screwdriver body 1. At the same time, a cover 4 is provided at the rear of the storage compartment. The cover 4 is engaged in the storage compartment by friction. A connecting plate 11 is provided at the rear of the electric screwdriver body 1. Several fixing slots 12 are evenly spaced on the side of the connecting plate 11. An adjusting screw hole 26 is provided at the end of the first handle splicing piece 21 near the electric screwdriver body 1. A locking mechanism 3 is installed in the adjusting screw hole 26. The locking mechanism 3 is used to lock the relative position between the electric screwdriver body 1 and the storage handle 2.

[0035] A rotating shaft 13 is fixedly installed on both ends of the connecting plate 11. Two connecting ears 23 are provided on the first grip splicing piece 21. Each rotating shaft 13 is rotatably installed in the through hole of a connecting ear 23.

[0036] The second grip splicing piece 22 is provided with a J-shaped positioning block 27, and the first grip splicing piece 21 is provided with a positioning slot 28 that cooperates with the positioning block 27.

[0037] The locking mechanism 3 includes an adjusting screw 31 and an arc block 33. The adjusting screw 31 is threaded into the adjusting screw hole 26. The arc block 33 is provided with a connecting seat 34. The upper end of the adjusting screw 31 is provided with a knob 32, and its lower end is rotatably connected to the connecting seat 34. The lower end of the arc block 33 is provided with a fixing tooth 35 that cooperates with the fixing groove 12.

[0038] The first storage compartment 24 is equipped with two limiting blocks 37, and an arc-shaped block 33 is formed between the two limiting blocks 37. The arc-shaped block 33 is slidably installed in the mounting groove 38. A guide block 36 is provided on the arc-shaped block 33, and a guide groove 39 is provided on the limiting block 37. The guide block 36 is slidably installed in the guide groove 39.

[0039] Working principle: When the electric screwdriver body 1 needs to be stored in the retractable handle 2, first remove the cover 4, then separate the first handle splice 21 and the second handle splice 22. Next, rotate the electric screwdriver body 1; the shafts 13 at both ends of the connecting disc 11 rotate within the through holes of the connecting ears 23 on the first handle splice 21, placing the electric screwdriver body 1 into the first storage compartment 24. Then, insert the J-shaped positioning block 27 on the second handle splice 22 into the positioning slot 28 on the first handle splice 21, merging the first handle splice 21 and the second handle splice 22. At this point, the first storage compartment 24 and the second storage compartment 25 form a complete storage compartment, enclosing the electric screwdriver body 1. Finally, rotate the cover 4 to close the rear of the storage compartment.

[0040] Locking and unlocking operation: To lock the relative positions of the electric screwdriver body 1 and the retractable handle 2, rotate the knob 32 of the locking mechanism 3 to move the adjusting screw 31 downwards. Since the lower end of the adjusting screw 31 is rotatably connected to the connecting seat 34 of the arc-shaped block 33, the arc-shaped block 33 will slide downwards along the guide groove 39 within the mounting groove 38. The fixing tooth 35 at the lower end of the arc-shaped block 33 will engage in the fixing groove 12 on the side of the connecting plate 11, thereby restricting the rotation of the electric screwdriver body 1. Reverse rotation of the knob 32 moves the adjusting screw 31 upwards, causing the arc-shaped block 33 to slide upwards. The fixing tooth 35 disengages from the fixing groove 12, releasing the lock. The electric screwdriver body 1 can then rotate freely relative to the retractable handle 2 around the pivot 13.
