[0025] like Figures 1 to 6 As shown, the utility model provides

[0026] A gear switch comprises a shell body 1, wherein a base 2 is fixedly connected to the lower part of the shell body 1 through a buckle structure 3, and the buckle structure 3 is connected to facilitate users to replace internal components when they are damaged, and the machine can be installed in an integrated manner during tooling, which greatly enhances production efficiency and convenience for users; the buckle structure 3 comprises a clamping column 31 arranged on the base 2 and a bayonet 32 ​​arranged on the shell body 1; at least one gear piece 11 is arranged on the shell body 1, and the gear piece 11 is used to connect external electrical components to facilitate control of the fan's rotation direction, wind force and fan switch, etc.; a first extension portion 111 extends downward from the position where the gear piece 11 contacts the base 2; the first extension portion 111 is arranged with an inwardly bent undercut 112; a fixing groove 21 fixedly connected to the gear piece 11 is arranged on the base 2, and the undercut 112 arranged on the first extension portion 111 is matched and connected with the fixing groove 21, so that the installation is more secure and not easy to fall off or loosen after long-term use.

[0027] A second extension portion 311 extends outward from the upper end of the clamping column 31; the buckle is fixedly connected to the bayonet 32 ​​through the second extension portion 311. After the second extension portion 311 is fixedly connected to the bayonet 32, the fixing effect is more secure, and the base 2 will not fall off easily, thereby extending the service life of the gear switch.

[0028] The base 2 is provided with a rotating piece 22, and the user can select the direction of the fan's rotation, the wind force and the fan switch by rotating the rotating piece 22.

[0029] A rotating gear handle 12 and / or a wire-pulling pendulum 13 are provided on the shell body 1; the rotating piece 22 is abutted and connected to the bottom of the rotating gear handle 12 and / or the wire-pulling pendulum 13; the rotating piece 22 is rotated by rotating the rotating gear handle 12 and / or pulling the wire-pulling pendulum 13. After the user rotates the gear handle 12 and / or pulls the wire-pulling pendulum 13, the rotating piece 22 is driven to rotate. Because the rotating piece 22 is abutted and connected to the rotating gear handle 12 and / or the wire-pulling pendulum 13, the rotating piece 22 can be rotated when the rotating gear handle 12 and / or the wire-pulling pendulum 13 are working.

[0030] At least one fixed arm 14 is arranged on the outer periphery of the shell body 1 to extend outward, and the setting of the fixed arm 14 allows the gear switch to be installed inside the fan; a spring fixing column 15 is arranged on the fixed arm 14, and a reset spring 16 is connected to the spring fixing column 15; the other end of the reset spring 16 is fixedly connected to the pull-wire swing rod 13, and by pulling the pull-wire swing rod 13, the rotating gear handle 12 is driven to rotate, and then the rotating plate 22 is driven to rotate. Because the reset spring 16 is provided, the pull-wire swing rod 13 can return to the initial position after each use by the user.

[0031] A snap ring 131 is arranged at the connection between the wire pull rod 13 and the rotating gear handle 12. The wire pull rod 13 is sleeved on the rotating gear handle 12 through the snap ring 131. The snap ring 131 is provided so that the wire pull rod 13 and the rotating gear handle 12 can work in linkage.

[0032] The rotating piece 22 extends outwardly with at least one contact 221; when the rotating piece 22 rotates, the contact 221 contacts the shift piece 11, and when the rotating piece 22 rotates, when the contact 221 contacts the shift piece 11, the fan's rotation direction, wind force and fan switch can be selected. Example

[0033] like Figure 1 As shown, when the user selects this gear switch, the user can pull the pull-wire swing rod 13. Since the pull-wire swing rod 13 is provided with a notch for fixing the reset spring 16, the notch can also be used to fix the pull rope of the pull-wire swing rod 13. When the user pulls the pull rope to drive the pull-wire swing rod 13, the rotating gear handle 12 arranged inside the shell body 1 will rotate. When the rotating gear handle 12 rotates, the rotating piece 22 will drive the contact 221 to rotate together. Then when the contact 221 contacts different gear pieces 11, the gear of the fan can be adjusted to select different wind forces. After each pulling of the pull-wire swing rod 13, the reset spring 16 will drive the pull-wire swing rod 13 back to the initial position. When the contact 221 does not contact the gear piece 11, the fan will not work. Example 1

[0034] like Figure 2 As shown, when the user selects this gear switch, he can rotate the rotating gear handle 12. When the rotating gear handle 12 is rotated, the rotating piece 22 will drive the contact 221 to rotate together. Then, when the contact 221 contacts different gear pieces 11, the gear of the fan can be adjusted to select different wind speeds; when the contact 221 does not contact the gear piece 11, the fan will not work. Example 2

[0035] like Figure 3As shown, when the user selects this type of gear switch, the user can pull the pull-wire swing rod 13. Since the pull-wire swing rod 13 is provided with a notch for fixing the reset spring 16, the notch can also be used to fix the pull rope of the pull-wire swing rod 13. When the user pulls the pull rope to drive the pull-wire swing rod 13, the rotating gear handle 12 arranged inside the shell body 1 will rotate. When the rotating gear handle 12 rotates, the rotating piece 22 will drive the contact 221 to rotate together, and then when the contact 221 contacts different gear pieces 11, the rotation angle of the fan can be adjusted; after each pulling of the pull-wire swing rod 13, the reset spring 16 will drive the pull-wire swing rod 13 back to the initial position; when the contact 221 does not contact the gear piece 11, the fan will not work.

[0036] The shell body 1 and the base 2 are connected by a snap-fit ​​structure 3. The snap-fit ​​structure 3 is provided to facilitate assembly and disassembly when internal components need to be replaced. A reverse buckle 112 is provided on the shift plate 11, which makes the installation more secure and not easy to fall off or loosen after long-term use.
