Description

Technical Field

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

[0002] An electric screwdriver, also known as an electric screwdriver or electric screwdriver, is a power tool widely used in many fields such as production and maintenance. It is characterized by high efficiency and convenience, and can easily tighten or loosen screws. It is especially suitable for assembly lines and other occasions. This tool is equipped with a mechanism to adjust and limit torque, which can easily adjust the screw tightness to meet different needs.

[0003] Existing retractable electric screwdrivers generally have a fixed shape and a large body size. When working in a confined space, operators need to frequently adjust their position. During long-term work, the uncomfortable working posture increases the operator's workload and affects work efficiency. Furthermore, when the electric screwdriver is fully charged, first-time users may accidentally grasp the switch, causing the device to start unexpectedly and posing a safety hazard. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a retractable electric screwdriver to solve the technical problems of existing electric screwdrivers having a large body size and fixed shape, making them inconvenient to operate in narrow spaces, and being prone to accidental activation of the device after charging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable electric screwdriver, comprising a first body, a charging mechanism, and an adjusting mechanism. The adjusting mechanism includes a rotating shaft, one end of which is provided with a gear, a fixing block is provided on one side of the gear, and a sliding groove is provided on one side of the fixing block. A locking push block is engaged and slidably disposed inside the sliding groove. The charging mechanism includes a charging head, one end of which is connected to a charging base via a connecting wire. A heat dissipation hole is provided on one side of the charging base, and a slot is provided on the top of the charging base. A baffle is provided on one side of the slot.

[0006] By adopting the above technical solution, the baffle is located at the central axis of the switch during charging, which effectively prevents accidental activation caused by accidental switch contact and increases charging safety.

[0007] Furthermore, a switch is provided on the outer surface of the first body, and a first handle is provided on one side of the switch.

[0008] By adopting the above technical solution, the switch is located on the outer surface of the first body, allowing the operator to easily access and control the start and stop of the electric screwdriver.

[0009] Furthermore, the first main body is rotatably connected to the second main body via an adjustment mechanism, and a blade is provided at one end of the second main body.

[0010] By adopting the above technical solution, a rotatable connection can be achieved between the first and second bodies of the adjustment mechanism, enabling the cutter head to work at different angles and positions.

[0011] Furthermore, a second grip is provided on the outer surface of the second body, and a protrusion is provided on the outer surface of the second grip.

[0012] By adopting the above technical solution, the protrusions on the second grip increase the friction when gripping, effectively preventing hand slippage and improving operational safety.

[0013] Furthermore, there are two second grips, which are symmetrically arranged along the central axis of the second body.

[0014] By adopting the above technical solution, the two symmetrically arranged second grips allow the operator to hold the device with their preferred hand, while also making it convenient for left-handed users.

[0015] Furthermore, a mounting groove is provided on one side of the second grip, a pull rope is provided in the mounting groove, and finger grooves are provided on both sides of the pull rope.

[0016] By adopting the above technical solution, the second grip provides an additional gripping area, allowing the operator to operate with both hands when needed, increasing torque and stability.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model, by setting up a charging mechanism and an adjustment mechanism, allows users to easily adjust the position of the second main body through the adjustment mechanism and fix it through the locking mechanism, thereby adapting to different working environments and operational needs, improving the flexibility and ease of use of the tool. When charging, the baffle of the charging mechanism is located at the central axis of the switch, effectively preventing the device from being accidentally started due to accidental switch contact during charging, significantly improving the safety of the charging process. The charging base and the main body also make the overall structure simpler, making it easier to carry and store.

[0019] 2. By incorporating a second grip and a pull rope, this utility model provides users with additional gripping points in situations where operation is difficult, such as when screws are rusty. This allows users to operate with both hands, thereby enhancing the strength and stability during operation. The pull rope provides users with a convenient way to hang the tool. Whether it is necessary to temporarily place the tool during work breaks or to store it after work is completed, the tool can be easily hung and stored using the pull rope, further improving the portability and efficiency of the tool.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Example 1:

[0027] A retractable electric screwdriver, such as Figures 1-4 As shown, the device includes a first main body 1, a charging mechanism 2, and an adjusting mechanism 4. The adjusting mechanism 4 includes a rotating shaft 401, with a gear 402 at one end of the rotating shaft 401. A fixing block 403 is provided on one side of the gear 402, and a sliding groove 404 is provided on one side of the fixing block 403. A locking push block 405 is engaged and slidably moved inside the sliding groove 404. The charging mechanism 2 includes a charging head 201, with one end of the charging head 201 connected to a charging base 203 via a connecting wire 202. A heat dissipation hole 204 is provided on one side of the charging base 203, and a slot 205 is provided on the top of the charging base 203. A baffle 206 is provided on one side of the slot 205. When charging, the baffle 206 is located at the central axis of the switch 3, effectively preventing accidental activation of the switch 3 and increasing charging safety. The locking push block 405 can slide in the sliding groove 404 and insert into the teeth of the gear 402 to firmly lock the position of the second main body 6, ensuring stability and safety during use.

[0028] See Figure 2A switch 3 is provided on the outer surface of the first body 1, and a first handle 5 is provided on one side of the switch 3. The switch 3 is located on the outer surface of the first body 1, so that the operator can easily reach and control the start and stop of the electric screwdriver. The first handle 5 provides a comfortable grip area for the operator, which helps to reduce hand fatigue during long-term use.

[0029] See Figure 2 The first body 1 is rotatably connected to the second body 6 via the adjustment mechanism 4. One end of the second body 6 is provided with a cutting head 12. The first body 1 and the second body 6 can be rotatably connected via the adjustment mechanism 4, so that the cutting head 12 can work at different angles and positions. Since the second body 6 can rotate relative to the first body 1, the operator can easily adjust the working angle of the cutting head 12 without frequently changing tools or making complex adjustments.

[0030] The implementation principle of this utility model is as follows: First, when in use, the operator can rotate the second main body 6 to rotate the second main body 6 to a suitable position. At the same time, the rotating shaft 401 drives the gear 402 to rotate, and then pushes the locking push block 405 to slide in the slide groove 404 and insert into the tooth of the gear 402 to restrict the rotation of the gear 402.

[0031] When charging is required, firstly, rotate the second body 6 to keep the first body 1 and the second body 6 in a relatively vertical position and lock them. Then, insert the charging base 203 into the slot 205 and connect it to the first body 1 for charging. At the same time, the baffle 206 is located at the central axis of the switch 3 to prevent the switch 3 from being accidentally activated.

[0032] Example 2:

[0033] See Figure 2 The outer surface of the second body 6 is provided with a second grip 7, and the outer surface of the second grip 7 is provided with a protrusion 8. The protrusion 8 on the second grip 7 increases the friction when gripping, effectively preventing the hand from slipping and improving the safety of operation. The second grip 7 and the protrusion 8 on it help reduce hand fatigue and discomfort caused by long-term operation, and improve the operator's work efficiency and comfort.

[0034] See Figure 2 There are two second grips 7, which are symmetrically arranged along the central axis of the second body 6. The symmetrical arrangement of the two second grips 7 allows the operator to hold the screwdriver with their preferred hand, and is also convenient for left-handed users. The symmetrical arrangement of the second grips 7 provides good balance for the electric screwdriver during operation.

[0035] See Figure 2The second grip 7 has a mounting groove 9 on one side, and a pull rope 10 is installed in the mounting groove 9. Finger grooves 11 are provided on both sides of the pull rope 10. The second grip 7 provides an additional gripping area, allowing the operator to operate with both hands when needed, increasing torque and stability. The pull rope 10 provides the operator with a convenient way to hang and carry.

[0036] The implementation principle of this utility model is as follows: First, when encountering situations such as rusted screws that make it difficult to use with one hand, the operator can hold the second handle 7 with the other hand to carry out the work. When it is necessary to temporarily put it down, the pull rope 10 can be pulled out through the finger groove 11 and the equipment can be suspended through the pull rope 10.
