Description

Technical Field

[0001] The utility model belongs to the technical field of electric tool gripping structures, and in particular relates to a handle component for an electric tool. Background Art

[0002] Most power tools currently on the market (such as pruning machines) have fixed handle positions, which means that once manufactured, the position of the handle relative to the tool body cannot be changed. While this design simplifies the production process and reduces costs, it also brings significant limitations:

[0003] Poor adaptability: Operators of different heights and arm lengths may feel inconvenience when using the same power tool due to inappropriate handle position, which affects work efficiency.

[0004] Low comfort: Holding tools in an unnatural posture for a long time can easily cause muscle tension, joint pain and other problems, which is not good for health.

[0005] Lack of flexibility: For some special application scenarios (such as working in narrow spaces), the fixed handle may limit the operating angle and method of the tool, reducing its practical value.

[0006] Safety issues: When the operator tries to adjust his body posture to accommodate the handle position, the risk of accidents increases, such as slipping or losing control of the tool.

[0007] Therefore, there is an urgent need to develop a new type of power tool that can flexibly adjust the handle position according to personal preferences and specific working conditions. Such an improvement not only helps to enhance the user experience but also further strengthens the product's market competitiveness. Based on these considerations, the present invention proposes an innovative design solution to address the various problems caused by the non-adjustable handles of existing power tools.

[0030] Reference Figures 1 to 5 A handle for an electric tool includes an assembly base 100 and an adjustment handle 200 mounted on the assembly base 100. The assembly base 100 is assembled on the rod 300 of the electric tool. The assembly base 100 is provided with a through slot 101 for the rod 300 to pass through. One side of the through slot 101 has an opening 102. A first plate 106 and a second plate 107 are respectively provided on either side of the opening 102. The first plate 106 is equipped with a locking shaft 110. One end of the locking shaft 110 is equipped with a pull rod 120. The pull rod 120 is equipped with a locking trigger 130. The other end of the locking shaft 110 passes through the first plate 106 and is fixedly connected to the second plate 107. This design allows the position of the handle 200 on the rod 300 to be adjusted by loosening or tightening the locking trigger 130.

[0031] The present application provides an adjustable handle 200. Specifically, the assembly base 100 is provided with an adjustment slot 103, in which an adjustment button 140 is slidably mounted. A spring 150 is installed between the adjustment button 140 and the bottom of the adjustment slot 103. The adjustment button 140 is provided with a first limiting tooth 141 and a second limiting tooth 142. The inner wall of the adjustment slot 103 is provided with a first limiting slot 104 that cooperates with the first limiting tooth 141. The adjustment handle 200 is provided with a second limiting slot 201 that cooperates with the second limiting tooth 142. When the handle needs to be adjusted, the adjustment button 140 is pressed so that the second limiting tooth 142 disengages the second limiting slot 201, and the adjustment handle 200 can be rotated. When the adjustment is in place, the adjustment button 140 is released, and the adjustment button 140 rebounds, causing the second limiting tooth 142 to engage the second limiting slot 201, thereby fixing the adjustment handle 200. The first limiting tooth 141 cooperates with the first limiting groove 104 to limit the position of the adjustment button 140. To prevent parts from being lost during disassembly, a clamping block 105 is provided on the inner wall of the adjustment groove 103, and a buckle 143 is provided on the adjustment button 140 to engage with the clamping block 105. This design prevents the adjustment button 140 from being ejected and falling due to the action of the spring 150 when the adjustment handle 200 is disassembled.

[0032] In the present application, the locking trigger 130 is tilted to avoid the adjustment button 140, reducing the possible interference between the two, while also optimizing the overall appearance design, making the product more beautiful and practical. Taking the axis of the rod 300 as the horizontal reference, the angle α between the center line of the locking trigger 130 and the axis of the rod 300 is in the range of: 30°≤α≤75°. This design takes into account ergonomic principles, the efficiency of force transmission during operation, and avoids the locking trigger 130 from interfering with the adjustment handle 200. The first plate 106 is provided with a limiting convex edge 108 on both sides of the locking trigger 130. This design is intended to limit the range of motion of the locking trigger 130 to prevent it from falling off, and can also prevent the locking trigger 130 from deviating in direction to interfere with the adjustment handle 200.

[0033] The locking trigger 130 is constructed from high-strength engineering plastic combined with metal inserts. This composite material not only ensures sufficient strength to withstand frequent operating pressure, but also reduces overall weight, making it more comfortable to hold for extended periods. Furthermore, the locking trigger 130's surface has been specially treated with a non-slip texture, ensuring a good grip even with sweaty or wet hands.

[0034] Furthermore, the second plate 107 is provided with a protrusion, within which is mounted a locking head 111 fixedly connected to the locking shaft 110. When disassembling the handle, the locking trigger 130 can be removed by removing the locking head 111. A reinforcing rib 109 is provided on the side of the protrusion near the rod 300. This design enhances the mechanical strength and durability of the connection between the first plate 106 and the assembly base 100, extending its service life and preventing fracture at the connection between the first plate 106 and the assembly base 100 due to overtightening.

[0035] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention is based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field fall within the protection scope of the present invention.
