AI Technical Summary
Existing ratchet screwdrivers require the use of a socket and an L-shaped lever when repairing machinery, making them inconvenient to carry and use.
A ratchet screwdriver for power engineering was designed. By setting a groove and a slider on the ratchet screwdriver body, a sleeve is fixedly installed on the slider. The extension and folding of the sleeve are realized by a drive component and a folding component, which increases the length for easy use and forms a T-shaped or L-shaped structure to facilitate rotation under force.
It enables easier screw installation and removal without the need for an additional lever, making it particularly suitable for deeper locations and improving ease of use and portability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of ratchet screwdriver technology, specifically a ratchet screwdriver for power engineering. Background Technology
[0002] A ratchet screwdriver is a specially designed tool that uses a ratchet mechanism to achieve unidirectional rotation, thereby continuously tightening or loosening screws without moving the handle;
[0003] When using existing ratchet screwdrivers, people often need to use a socket to install and remove screws when repairing machinery. This requires the use of an L-shaped lever that matches the socket. Therefore, when repairing machinery, people need to carry not only the screwdriver and socket, but also the lever, which makes it inconvenient to carry and use. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a ratchet screwdriver for power engineering. It solves the technical problem that when using existing ratchet screwdrivers, people often need to use a socket to install and remove screws when repairing machinery. This requires the use of an L-shaped lever that matches the socket. Therefore, when repairing machinery, people need to carry not only the screwdriver and socket but also the lever, which makes it inconvenient to carry and use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ratchet screwdriver for power engineering, comprising a ratchet screwdriver body, four sliding grooves on the ratchet screwdriver body, sliders slidably installed in the sliding grooves, sleeves fixedly installed between the sliders, the sleeves fitted onto the ratchet screwdriver body, a drive assembly between the sleeves and the ratchet screwdriver body, a folding assembly on the outer wall of the sleeve, the drive assembly including a lead screw, a threaded groove on the lower wall of the ratchet screwdriver body, the lead screw engaging with the threaded groove, the other end of the lead screw rotatably installed on the lower wall of the sleeve, the folding assembly including a pair of bearing grooves and a pair of handles, the pair of bearing grooves being opened on the two side walls of the sleeve, shafts fixedly installed on the upper and lower side walls of the bearing grooves, a guide groove on the handle, a guide block slidably installed in the guide groove, the guide block rotatably connected to the shaft, a slot being opened in the bearing groove and located on one side of the shaft, the handle matching the slot.
[0006] Preferably, the other end of the lead screw passes through the sleeve and is fixedly mounted with a rotating disk.
[0007] Preferably, an anti-slip pad is fixedly installed on the handle.
[0008] Preferably, two adjacent slides in the four slides are perpendicular to each other.
[0009] Preferably, the groove has a dovetail groove structure, and the slider has a dovetail block structure.
[0010] Beneficial effects
[0011] This utility model provides a ratchet screwdriver for power engineering, solving the technical problem that existing ratchet screwdrivers often require the use of a socket to install and remove screws when repairing machinery. This necessitates the use of an L-shaped lever that mates with the socket, making it inconvenient to carry and use in addition to the screwdriver, socket, and lever. This utility model uses a drive assembly to move the socket out from the lower end of the ratchet screwdriver body, thereby increasing the total length of the ratchet screwdriver body and the socket. This facilitates the use of the ratchet screwdriver body at deeper locations. Through a folding assembly, the handle is moved out from inside the socket, forming a T-shape or L-shape with the ratchet screwdriver body, which facilitates the rotation of the ratchet screwdriver body under force and makes the ratchet screwdriver body easy to carry.

[0015] 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.
[0016] Please see Figure 1-2This utility model provides a technical solution: a ratchet screwdriver for power engineering, including a ratchet screwdriver body 1, four sliding grooves 2 on the ratchet screwdriver body 1, sliders 3 slidably installed in the sliding grooves 2, sleeves 4 fixedly installed between the sliders 3, the sleeves 4 being fitted onto the ratchet screwdriver body 1, a driving assembly between the sleeves 4 and the ratchet screwdriver body 1, a folding assembly on the outer wall of the sleeves 4, the driving assembly including a lead screw 5, and a threaded groove on the lower wall of the ratchet screwdriver body 1. The lead screw 5 is engaged in the threaded groove, and the other end of the lead screw 5 is rotatably mounted on the lower wall of the sleeve 4. The folding assembly includes a pair of bearing grooves 6 and a pair of handles 7. The pair of bearing grooves 6 are opened on both sides of the sleeve 4. The upper and lower sides of the bearing grooves 6 are fixedly installed with shafts 8. The handles 7 are provided with guide grooves 9. The guide blocks 10 are slidably installed in the guide grooves 9. The guide blocks 10 are rotatably connected to the shafts 8. The bearing grooves 6 are provided with slots 11 on one side of the shafts 8. The handles 7 are matched with the slots 11.
[0017] In this embodiment, the other end of the lead screw 5 passes through the sleeve 4 and is fixedly mounted with a rotating disk 12.
[0018] In this embodiment, an anti-slip pad 13 is fixedly installed on the handle.
[0019] In this embodiment, two adjacent slides 2 of the four slides 2 are perpendicular to each other.
[0020] In this embodiment, the slide groove 2 is configured as a dovetail groove structure, and the slider 3 is configured as a dovetail block structure.
[0021] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0022] Example: As shown in the accompanying drawings, during use, rotating the rotating disk 12 causes the lead screw 5 to rotate. Since the lead screw 5 and the ratchet screwdriver body 1 are connected by a threaded groove, the rotation of the lead screw 5 drives the ratchet screwdriver body 1. At this time, the ratchet screwdriver body 1 moves along the path of the slide groove 2 under the action of the slider 3, thereby increasing the total length of the ratchet screwdriver body 1 and the sleeve 4. This rotates the handle 7 from the bearing groove 6 to a horizontal position, pushing the handle 7 so that the guide block 10 moves in the guide groove 9, thereby inserting the rear end of the handle 7 into the slot 11, which facilitates the ratchet screwdriver body 1 to rotate under force.
[0023] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
