Description

Technical Field

[0001] This utility model relates to the field of electric drill technology, and more specifically, to an electric drill extension operating lever. Background Technology

[0002] An electric drill is a drilling tool powered by electricity. It is a common and widely demanded product among power tools. It mainly consists of a motor, drill bit, chuck, control switch, and handle. The motor receives power from the wire and runs, driving the chuck and drill bit to rotate through a gear transmission system, thereby drilling a hole in the target material. Electric drills come in various sizes to suit drilling needs of different materials and thicknesses. In addition, electric drills also have different function modes, such as forward and reverse rotation and electronic speed control, to adapt to different work scenarios. Electric drills are widely used in industries such as construction, decoration, and furniture manufacturing, and are an indispensable and powerful tool in these industries.

[0003] A search revealed that publication number CN219402431 U discloses an adjustable-length electric drill extension bracket, including an extension plate. The extension plate has an adjustment component within its inner cavity. A first through-slot is formed at the top of the extension plate. The top of the adjustment component passes through the first through-slot and is bolted to a fixing box. A clamping component is formed within the fixing box, and a second through-slot is formed at the top of the fixing box. Through the cooperation of a threaded rod, a moving block, and a clamping plate, the electric drill can be easily fixed to the fixing box by the construction worker, preventing it from falling during use. Through the cooperation of a lead screw, an extended threaded sleeve, and a second handle, the extension length of the electric drill can be easily adjusted according to different construction conditions, facilitating use. Through the cooperation of a first sliding groove, a first sliding block, a mounting plate, a pull rod, a fixing block, and a first handle, the fixing block is positioned directly above the electric drill switch. The construction worker can control the electric drill by pulling the first handle. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing electric drill extension rods often make it difficult to adjust the drill angle after extension operations, which is not easy to operate when performing maintenance or installation in confined spaces, affecting work efficiency and quality.

[0005] Therefore, an extension rod for electric drills is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an extension rod for an electric drill to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an extension operating rod for an electric drill, comprising an electric drill, a telescopic component, an adjusting component, and a connecting component. The connecting component is disposed below the electric drill, and the telescopic component is disposed below the connecting component. An adjusting component is installed on one side of the telescopic component.

[0008] Preferably, the telescopic assembly includes a first telescopic rod, a first mounting shaft, and a first sleeve. The first mounting shaft is provided at the top of the first telescopic rod, and the first sleeve is rotatably provided on the outer diameter of the first mounting shaft.

[0009] Preferably, the adjustment assembly includes an adjustment frame, a sliding groove, a sliding shaft, a connecting rod, a second telescopic rod, a second mounting shaft, and a second sleeve. The two ends of the second mounting shaft are fitted with second sleeves, and a connecting rod is installed below the outer diameter of the second mounting shaft. A sliding shaft is provided at the end of the connecting rod away from the second mounting shaft, and the sliding shaft is slidably disposed inside the sliding groove. The sliding groove is opened on the side of the adjustment frame away from the connecting rod, and a second telescopic rod is provided below the sliding shaft.

[0010] Preferably, the connecting component includes an upper connecting block and a lower connecting block, with the lower connecting block disposed below the upper connecting block.

[0011] Preferably, the upper connecting block is connected to the lower connecting block by bolts to form a detachable structure, and the sliding shaft forms a sliding structure within the sliding groove.

[0012] Preferably, the first mounting shaft and the first sleeve are connected by a rotatable connection, and the second mounting shaft and the second sleeve are connected by a rotatable connection.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with the prior art, this electric drill extension rod drives the sliding shaft to slide in the sliding groove through the extension and retraction of the second telescopic rod, causing the connecting rod connected above the sliding shaft to move. The movement of the connecting rod will drive the second mounting shaft above it to rotate in the second sleeve, causing the lower connecting block above the second sleeve to rise or fall. Since the height of the first sleeve on the side of the lower connecting block away from the second sleeve is fixed, when the lower connecting block rises or falls, it will perform a circular motion with the first sleeve as the center. By controlling the extension and retraction height of the second telescopic rod, the rotation angle of the motor can be controlled to achieve angle adjustment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] As attached Figures 1 to 6 The electric drill extension lever shown includes an electric drill 1, a telescopic component 2, an adjustment component 3, and a connecting component 4. The connecting component 4 is located below the electric drill 1, and the telescopic component 2 is located below the connecting component 4. The adjustment component 3 is installed on one side of the telescopic component 2.

[0026] Specifically: When it is necessary to extend the motor, the motor is first disassembled to separate the upper connecting block 13 and the lower connecting block 14. A telescopic component 2 and an adjustment component 3 are added between the upper connecting block 13 and the lower connecting block 14. The motor is extended by extending and retracting the first telescopic rod 5 and the second telescopic rod 12 simultaneously, so as to achieve the purpose of maintenance or installation at different heights. By fixing the first telescopic rod 5, the second telescopic rod 12 is extended and retracted to adjust the angle of the electric drill 1 so that the electric drill 1 can be maintained or installed in a confined space.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 6 As shown below, see details:

[0029] In a preferred embodiment, the telescopic assembly 2 includes a first telescopic rod 5, a first mounting shaft 6, and a first sleeve 7. The first mounting shaft 6 is provided at the top of the first telescopic rod 5, and the first sleeve 7 is rotatably provided on the outer diameter of the first mounting shaft 6. When it is necessary to extend the motor, the telescopic assembly 2 and the adjustment assembly 3 are installed first. By simultaneously extending and retracting the first telescopic rod 5 and the second telescopic rod 12, the lower connecting block 14 is driven to move upward, thereby driving the electric drill 1 to move upward, achieving the purpose of extension.

[0030] In a preferred embodiment, the adjustment assembly 3 includes an adjustment frame 8, a sliding groove 9, a sliding shaft 10, a connecting rod 11, a second telescopic rod 12, a second mounting shaft 15, and a second sleeve 16. The two ends of the second mounting shaft 15 are fitted with the second sleeve 16, and the connecting rod 11 is installed below the outer diameter of the second mounting shaft 15. The end of the connecting rod 11 away from the second mounting shaft 15 is provided with the sliding shaft 10, and the sliding shaft 10 is slidably disposed inside the sliding groove 9. The sliding groove 9 is opened on the side of the adjustment frame 8 away from the connecting rod 11, and the second telescopic rod 12 is provided below the sliding shaft 10.

[0031] In a preferred embodiment, the connecting assembly 4 includes an upper connecting block 13 and a lower connecting block 14. The lower connecting block 14 is located below the upper connecting block 13. When the angle of the electric drill 1 needs to be adjusted, the first telescopic rod 5 is fixed, and the second telescopic rod 12 is raised or lowered. The extension and retraction of the second telescopic rod 12 drives the sliding shaft 10 to slide in the sliding groove 9, causing the connecting rod 11 connected above the sliding shaft 10 to move. The movement of the connecting rod 11 will drive the second mounting shaft 15 above it to rotate in the second sleeve 16, causing the electric drill 1 above the second sleeve 16 to rise or fall. Since the height of the first telescopic rod 5 is fixed, when the second telescopic rod 12 rises or falls, it will perform a circular motion with the first mounting shaft 6 above the first telescopic rod 5 as the center. By controlling the extension and retraction height of the second telescopic rod 12, the angle of the motor rotation can be controlled to achieve angle adjustment.

[0032] In a preferred embodiment, the upper connecting block 13 is connected to the lower connecting block 14 by bolts to form a detachable structure. The sliding shaft 10 forms a sliding structure in the sliding groove 9. When it is necessary to extend the motor, the motor can be disassembled and the telescopic component 2 can be added to extend the motor by removing the bolts. When it is not needed, the telescopic component 2 can be quickly disassembled and the electric drill 1 can be reassembled.

[0033] In a preferred embodiment, the first mounting shaft 6 and the first sleeve 7 are connected by a rotatable connection, and the second mounting shaft 15 and the second sleeve 16 are connected by a rotatable connection. The rotatable connection allows for easy angle adjustment of the motor, making it convenient for maintenance or installation in confined spaces. It is not only easy to operate, but also does not affect work efficiency and quality.

[0034] The working process of this utility model is as follows: First, when it is necessary to extend the motor, the motor is first disassembled to separate the upper connecting block 13 and the lower connecting block 14. A telescopic component 2 and an adjusting component 3 are added between the upper connecting block 13 and the lower connecting block 14. The motor is extended by extending and retracting the first telescopic rod 5 and the second telescopic rod 12 simultaneously, so as to achieve the purpose of maintenance or installation at different heights. By fixing the first telescopic rod 5, the second telescopic rod 12 is extended and retracted to adjust the angle of the electric drill 1 so that the electric drill 1 can be maintained or installed in a confined space. When it is necessary to extend the motor, the telescopic component 2 and the adjusting component 3 are first installed. The lower connecting block 14 is moved upward by extending and retracting the first telescopic rod 5 and the second telescopic rod 12 simultaneously, thereby moving the electric drill 1 upward to achieve the purpose of extension.

[0035] When the angle of the electric drill 1 needs to be adjusted, the first telescopic rod 5 is fixed, and the second telescopic rod 12 is raised or lowered. The extension and retraction of the second telescopic rod 12 causes the sliding shaft 10 to slide within the sliding groove 9, which in turn moves the connecting rod 11 connected above the sliding shaft 10. The movement of the connecting rod 11 causes the second mounting shaft 15 above it to rotate within the second sleeve 16, causing the electric drill 1 above the second sleeve 16 to rise or fall. Since the height of the first telescopic rod 5 is fixed, when the second telescopic rod 12 rises or falls, it will move in a circle around the first mounting shaft 6 above the first telescopic rod 5 as the center. The extension rod 12 is used to control the height of the extension, thereby controlling the angle of the motor rotation. When the motor needs to be extended, the extension component 2 can be added by disassembling the bolts. When not needed, the extension component 2 can be quickly disassembled and the drill 1 can be reassembled. The rotating connection allows for easy angle adjustment of the motor, making it suitable for maintenance or installation in confined spaces. It is easy to operate and does not affect work efficiency or quality. The above describes the working principle of this drill extension rod.
