[0029] like Figures 1 to 5 As shown together, this embodiment provides a maintenance tool for thermal energy and power engineering, which includes a handle 1, a main cutting head 11 installed on the top of the handle 1, and a ring-shaped array of replacement cutting heads 2 installed on the top of the handle 1. The main cutting head 11 is located inside the replacement cutting heads 2. The main cutting head 11 is located at the center of the top of the handle 1, and the replacement cutting heads 2 are located in a circle outside the top of the handle 1. The replacement cutting heads 2 have the same structure and installation method as the main cutting head 11, and the difference lies in the shape of the cutting heads. Only the structure of the replacement cutting heads 2 is described here.

[0030] The bottom of the replacement cutter head 2 is fixedly connected with a connecting rod 21, and a slide groove 22 and a connecting groove 23 are provided inside the connecting rod 21. The slide groove 22 is communicated with the connecting groove 23, and the connecting groove 23 is cylindrical. The diameter of the connecting groove 23 is larger than the diameter of the slide groove 22. The slide groove 22 is used to ensure a stable connection with the connecting plate 24, and the connecting groove 23 is used to engage with the rubber block 25. At the same time, the locking of the magnetic block 26 can quickly achieve the purpose of installing the replacement cutter head 2 and the main cutter head 11, and this method is more stable than the installation method relying solely on the magnetic block 26. At the same time, due to the provision of multiple sets of replacement cutter heads 2, the staff can avoid carrying multiple sets of screwdrivers of different shapes, thereby reducing the weight of the tools carried and reducing the complexity.

[0031] A connecting plate 24 is fixedly connected to the inside of the handle 1, and a rubber block 25 is fixedly connected to the top of the connecting plate 24. The rubber block 25 is cylindrical. The connecting plate 24 is located inside the slide groove 22 and is movably connected to it. The rubber block 25 is located inside the connecting groove 23 and is movably connected to it. The rubber block 25 has a deformation function. It can slowly deform with the squeezing of the slide groove 22 until it is connected to its connecting groove 23. It can slowly fit into the connecting groove 23. At the same time, since its diameter is larger than the connecting groove 23, it can achieve a better locking function. At the same time, the inner structure of the top of the locking rod 3 is the same as above, which can facilitate the connection of the main cutting head 11.

[0032] A magnetic block 26 is installed at the bottom of the connecting rod 21. Iron blocks are installed inside the handle 1 and on both sides of the connecting plate 24. The magnetic block 26 is located on top of the iron block and is magnetically connected to it to increase the stability of the replacement blade head 2 and the handle 1, and the main blade head 11 and the locking rod 3.

[0033] The surface of the handle 1 is installed with anti-skid sheets 27, which are arranged in a ring array and at equal distances, which can increase the friction between the handle and the operator's hand so that the operator can better operate the screwdriver.

[0034] The handle 1 is internally movably sleeved with a locking rod 3, and the surface of the locking rod 3 is fixedly connected to a locking sleeve 31. The diameter of the locking sleeve 31 is larger than the locking rod 3. The surface of the locking sleeve 31 is provided with positioning holes 32, and there are two groups of positioning holes 32. The main cutting head 11 is located at the top of the inner side of the locking rod 3, and the structure is consistent with the connection method of the replacement cutting head 2 and the handle 1;

[0035] A cavity 33 is provided inside the handle 1, and the locking sleeve 31 is located inside the cavity 33 and is movably connected to it to facilitate the movement of the locking rod 3, thereby facilitating the position adjustment of the main cutting head 11 and operating on screws of different depths. A positioning piece 34 is installed inside the handle 1.

[0036] The positioning member 34 includes a sleeve 341 fixed inside the handle 1, and a slide rod 342 is movably sleeved inside the sleeve 341. The outer surface of the slide rod 342 is sleeved with a spring 343. Dampers 344 are provided on both sides of the spring 343 to ensure that the spring 343 can operate normally.

[0037] One end of the sliding rod 342 is fixedly connected to a positioning block 345, which is square in shape. One end of the positioning block 345 passes through one side of the sleeve 341 and extends to the inside of the positioning hole 32 and is movably connected to it. The positioning block 345 is movably connected to the sleeve 341, so that the locking rod 3 can be locked, thereby facilitating the positioning of the screwdriver.

[0038] The other end of the slide rod 342 is fixedly connected to a pull ring 346, which is located on the outer surface of the handle 1. One end of the spring 343 and the end close to the positioning block 345 are fixedly connected to the slide rod 342, and the other end of the spring 343 and the end close to the pull ring 346 are fixedly connected to the inner side of the shell 341, which facilitates the deformation operation of the spring 343.

[0039] When in use, multiple sets of replacement blade heads 2 are inserted into the top of the handle 1, and the connecting rod 21 is slowly extended into it along the top of the handle 1. During this process, the slide groove 22 will slowly fit with the rubber block 25, and slowly squeeze the rubber block 25 with the pressure, so that the rubber block 25 is deformed inside the slide groove 22. At the same time, the slide groove 22 slowly covers the connecting plate 24 until the rubber block 25 coincides with the connecting groove 23. At this time, the rubber block 25 will slowly return to its original shape as the pressure is released until it coincides with the connecting groove 23, and the connecting plate 24 will also fit with the slide groove 2 2 overlap, and after the installation is completed, the magnetic block 26 at the bottom of the connecting rod 21 will be magnetically connected to the iron block inside the handle 1, so that the connection can be more stable. When installing the main cutting head 11, the operation is the same. When removing the main cutting head 11 or the replacement cutting head 2, just pull it directly. Different cutting heads can be replaced according to screws of different shapes. This method can save the number of screwdrivers carried by the staff, thereby reducing the weight inside the tool bag. At the same time, this method can make the installation of the main cutting head 11 and the replacement cutting head 2 more secure and reduce the risk of them falling off;

[0040] When working on screws of different depths, refer to Figure 4 and Figure 5 When the locking sleeve 31 rises to the top of the cavity 33, the pulling force on the pull ring 346 is released, and the spring 343 can restore its deformation and push the sliding rod 342 and the positioning block 345 toward the positioning hole 32 until they are located inside the positioning hole 32, thereby completing the positioning of the locking rod 3. In this way, screws of different depths can be operated, thereby increasing the practicality of the screwdriver.

[0041] It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention. In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims of this application.
