[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] The present invention provides a technical solution: As Figure 1 - Figure 4 shown, a dual-protection drive power supply includes a power supply main body 1. An input power cord 2 is fixedly connected to one side of the power supply main body 1. An output power cord 3 is fixedly connected to the side of the power supply main body 1 away from the input power cord 2. A gear 5 is rotatably connected to a position near the center of the bottom of the power supply main body 1. A polygonal knob 7 is fixedly connected to the side of the gear 5 away from the power supply main body 1. A rack 8 is externally engaged with the gear 5. One end of the rack 8 is fixedly connected to a sliding mounting plate 4. One side of the sliding mounting plate 4 is slidably connected to the bottom of the power supply main body 1. A positioning mounting plate 12 is fixedly connected to the bottom of the power supply main body 1 at a position away from the sliding mounting plate 4. A clamping block 6 is externally engaged with the gear 5 on the side away from the rack 8. There are two groups of clamping blocks 6 arranged symmetrically in an "eight" shape. The relatively closest sides of the clamping blocks 6 are provided with beveled surfaces. A pushing component is arranged on the side of the clamping block 6 away from the gear 5.

[0022] The rack 8 is slidably connected to a slide rail 9 on the side away from the gear 5. The slide rail 9 is arranged in an "L" shape and is fixedly connected to the bottom of the power supply main body 1.

[0023] One end of the rack 8 away from the sliding mounting plate 4 is fixedly connected to a return spring 10. The end of the return spring 10 away from the rack 8 is fixedly connected to one side of the positioning mounting plate 12. A telescopic box 11 is arranged outside the return spring 10, and the telescopic box 11 is fixedly connected to the bottom of the power supply main body 1.

[0024] The pushing component includes a positioning spring 13. The positioning spring 13 is fixedly connected to the side of the clamping block 6 away from the gear 5. The end of the positioning spring 13 away from the clamping block 6 is fixedly connected to a positioning plate 15, and the positioning plate 15 is fixedly connected to the bottom of the power supply main body 1.

[0025] A threaded rod 14 is rotatably connected to one side of the clamping block 6 close to the positioning spring 13. The threaded rod 14 is arranged inside the positioning spring 13, and the outer part of the threaded rod 14 away from the clamping block 6 is arranged inside the positioning plate 15.

[0026] A positioning groove 16 is formed on one side of the positioning plate 15. A positioning sleeve 17 is slidably connected inside the positioning groove 16. The positioning sleeve 17 is rotatably connected to the outer part of the threaded rod 14. A positioning block 18 is fixedly connected to the outer part of the positioning sleeve 17. There are two groups of positioning blocks 18 symmetrically fitted inside the positioning groove 16. One end of the threaded rod 14 away from the clamping block 6 is fixedly connected to a twisting plate 19.

[0027] Working principle: First, align the sliding mounting plate 4 with the bolt hole, insert the bolt through the sliding mounting plate 4 and align it with the bolt hole, and then rotate the bolt to fix the sliding mounting plate 4. When the length of the power supply main body 1 is insufficient, the threaded rod 14 close to the sliding mounting plate 4 can be rotated to make the threaded rod 14 rotate inside the positioning sleeve 17. Since the positioning sleeve 17 is restricted inside the positioning groove 16 by the positioning block 18, the positioning sleeve 17 is ensured not to rotate, so that the threaded rod 14 can adjust the length. When the clamping block 6 controlled by this threaded rod 14 disengages from the outside of the gear 5, any wrench can be placed outside the polygonal knob 7 and rotated. Due to its polygonal structure, it can be ensured that most wrenches can be adapted. At this time, rotating the wrench can drive the polygonal knob 7 and the gear 5 to rotate, so that the gear 5 can drive the rack 8 to slide along the slide rail 9, thereby pushing out the sliding mounting plate 4. When the gear 5 rotates, it will slide on the inclined plane of the clamping block 6 that has not disengaged from the outside of the gear 5. The clamping block 6 will be pushed to compress the positioning spring 13. At the same time, the clamping block 6 will drive the threaded rod 14 to move, and the threaded rod 14 will drive the positioning sleeve 17 to slide inside the positioning groove 16 to achieve the effect of one-way limit. When the positioning mounting plate 12 reaches the bolt hole, it can be fixedly installed. The unilateral inclined plane structure of the clamping block 6 ensures that the gear 5 will not reverse to cause the rack 8 to contract. To adjust the distance smaller, only need to rotate the threaded rod 14 close to the positioning mounting plate 12, and use the above operation in the same way. Then rotate the gear 5 in the reverse direction to control the distance between the sliding mounting plate 4 and the positioning mounting plate 12 to decrease.

[0028] When it is necessary to quickly reset the sliding mounting plate 4, only need to control both clamping blocks 6 to disengage from the outside of the gear 5. At this time, the elastic force and tensile force of the reset spring 10 can ensure that the rack 8 will drive the sliding mounting plate 4 to reset. And when the reset spring 10 expands and contracts, it is shielded and protected by the telescopic box 11, which can also effectively avoid pinching the operator's fingers. The twisting plate 19 makes it more convenient to rotate the threaded rod 14. After the power supply main body 1 is installed, electric energy can be input through the input power cord 2, and after being processed by the power supply main body 1, it is output from one end of the output power cord 3, realizing the overall use effect.

[0029] It should be noted that in this device, the gear 5 drives the rack 8 to move, achieving the effect of controlling the distance between the sliding mounting plate 4 and the positioning mounting plate 12. Then, the eight-shaped unilateral inclined plane structure of the clamping block 6 is adopted to achieve the effect of controlling the rotation direction of the gear 5. The clamping block 6 is telescoped by the positioning spring 13, and the threaded rod 14 can not only be telescoped but also rotate to control the position of the clamping block 6, increasing the stability after adjusting the distance between the sliding mounting plate 4 and the positioning mounting plate 12.

[0030] It should also be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
