[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] As attached Figure 1 To Attachment Figure 4 As shown: it includes a switch chassis 1, and the inner wall of the switch chassis 1 is fixedly connected to two gear bars 2 of the same size, and the subsequent fixation of the switch is facilitated by the provision of the gear bars 2.

[0022] A fixing component 3 is installed on the inner wall of the switch chassis 1. The fixing component 3 includes a fixing frame 301. A group of threaded holes 302 arranged at equal distances are opened on the outer surface of the fixing frame 301. The multiple threaded holes 302 can enable the switch to be installed at different heights, which can ensure the normal operation of the subsequent switch. The inner wall of the threaded hole 302 is threadedly connected with a hexagonal bolt 303. The set hexagonal bolt 303 can fix the switch, which is convenient for subsequent normal use.

[0023] A movable fixing component 4 is installed on the outer surface of the fixing component 3, and the movable fixing component 4 includes two movable grooves 401. The two movable grooves 401 are both opened on the outer surface of the mounting plate 5, and the outer surface of the movable groove 401 is slidably connected with a movable block 402. The sliding connection between the movable groove 401 and the movable block 402 is utilized. When the movable block 402 is pushed from the inside of the movable groove 401, the guiding and limiting of the movable groove 401 can ensure that the movable groove 401 will not be unique when moving, and the subsequent clamping effect of the movable block 402 can be guaranteed.

[0024] The movable fixed component 4 also includes a connecting block 403, the bottom surface of the connecting block 403 is fixedly connected to the upper surface of the mounting plate 5, and a double-headed motor 404 is installed on the upper surface of the connecting block 403 by bolts. The bolt-type installation of the double-headed motor 404 can facilitate subsequent disassembly and maintenance by subsequent staff, and can ensure the subsequent normal use of the device.

[0025] The output end of the double-headed motor 404 is fixedly connected to an extension rod 405, and the end of the extension rod 405 away from the double-headed motor 404 is fixedly connected to a first gear 406. Through the operation of the double-headed motor 404, the extension rod 405 can be driven to rotate, thereby driving the first gear 406 to rotate, which can facilitate the subsequent fixation of the switch.

[0026] Two long plates 407 are fixedly connected to the outer surface of the connecting block 403 , and threaded rods 408 are rotatably connected to the outer surface of the long plates 407 . The top ends of the two threaded rods 408 are fixedly connected to second gears 409 , and the second gears 409 mesh with the first gears 406 .

[0027] Through the meshing between the first gear 406 and the second gear 409 and utilizing the operation of the double-headed motor 404, the threaded rod 408 can be driven to rotate, thereby facilitating the subsequent movement of the moving block 402 and further ensuring the stability of the moving block 402 after being fixed.

[0028] The bottom ends of the two threaded rods 408 are fixedly connected with a circular plate 410. The circular plate 410 can prevent the threaded rods 408 from excessively rotating, and can ensure the stability of the threaded rods 408 during subsequent rotation.

[0029] The outer surfaces of the two threaded rods 408 are both threadedly connected to a conical plate 411, and the upper surface of the conical plate 411 is fixedly connected to a guide rod 412. Guided by the guide rod 412, the conical plate 411 can be more stable when moving, and the stability of the conical plate 411 when moving can be guaranteed, thereby ensuring the subsequent clamping effect of the moving block 402.

[0030] The outer surfaces of the two guide rods 412 are respectively slidably connected to the outer surfaces of the two long plates 407, which can ensure the guiding effect of the guide rods 412 on the conical plate 411 and the stability of the conical plate 411 when moving.

[0031] Two circular hole plates 6 are installed on the front of the installation plate 5, which realizes the installation of the switch and facilitates the subsequent normal use of the switch.

[0032] Working principle: When using this device, first install this device to the use area, then install the switch to the upper surface of the circular hole plate 6 by bolts, and then fix it with the hexagonal bolts 303, and then adjust the installation position of the switch according to the specific situation on site, and then move the mounting plate 5 to a suitable position, start the switch of the double-headed motor 404, and the double-headed motor 404 drives the extension rod 405 to rotate. During the process, the engagement between the first gear 406 and the second gear 409 can drive the threaded rod 408 to rotate. During the process, the guide rod 412 guides the conical plate 411, so that the conical plate 411 can be moved to the inside of the moving groove 401. The shape of the conical plate 411 can slowly push out the moving block 402, and the connection between the moving block 402 and the gear bar 2 can be used to fix the mounting plate 5 without using a spring. There is no risk of falling off after long-term use, and the normal use of the subsequent switch can be guaranteed.
