[0010] Furthermore, in a preferred configuration, the housing has connection holes on both sides, the connection holes extend to the fixing plate, and a fixing structure is inserted inside the connection holes, with the fixing structure extending to the bottom of the housing.

[0011] In addition, a preferred structure is that a limiting block is provided on the top of the insulating disk, and the limiting block is compatible with the limiting opening and the limiting groove.

[0012] Furthermore, in a preferred configuration, when the spring is in a fully compressed state, the limiting block is located outside the fixed plate and does not contact the fixed plate.

[0013] In addition, a preferred structure is that the bottom of the housing is provided with a connecting sleeve, the bottom of the connecting sleeve is provided with an insulating gasket, and the middle of the housing is provided with a slot, and the inside of the slot is provided with a contact point corresponding to the limiting groove.

[0014] In addition, a preferred structure is that the bottom of the limiting block is provided with a compression pad, and the compression pad is in contact with the contact point.

[0015] The beneficial effects of this utility model are as follows: First, the adjustment mechanism at the top of the housing enables the band switch to be speed-adjusted. Then, by pressing and rotating the adjustment mechanism, and then by the spring resetting, the limiting block at the bottom of the adjustment mechanism contacts different contacts, making it more convenient to adjust the speed of the band switch.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A speed control band switch includes a mounting block 2, a mounting sleeve 3 is provided on the top of the mounting block 2, and an adjustment mechanism 4 is provided inside the mounting sleeve 3;

[0024] The bottom of the adjusting mechanism 4 is fitted with a sleeve plate 41, and extension pieces 42 are provided on both sides of the sleeve plate 41. The end of the extension piece 42 is provided with a limit opening 43. The bottom of the adjusting mechanism 4 is connected to a connecting block 47, and a fixing plate 44 is provided on the connecting block 47. An insulating plate 48 is provided at the bottom of the connecting block 47.

[0025] A spring 46 is fitted on the connecting block 47, and the spring 46 is located between the fixed plate 44 and the adjusting mechanism 4.

[0026] In addition, a limiting groove 45 is provided on the fixed plate 44, and the limiting groove 45 is compatible with the limiting opening 43 provided on the extension piece 42.

[0027] Furthermore, the housing 1 has connection holes 49 on both sides, and the connection holes 49 extend to the fixing plate 44. A fixing structure 7 is inserted into the connection hole 49, and the fixing structure 7 extends to the bottom of the housing 1.

[0028] Meanwhile, a limiting block 410 is provided on the top of the insulating disk 48, and the limiting block 410 is compatible with the limiting opening 43 and the limiting groove 45.

[0029] Furthermore, when the spring 46 is in a fully compressed state, the limiting block 410 is outside the fixed plate 44 and does not contact the fixed plate 44.

[0030] Furthermore, a connecting sleeve 6 is provided at the bottom of the housing 1, and an insulating gasket 5 is provided at the bottom of the connecting sleeve 6. A slot 101 is provided in the middle of the housing 1, and a contact 102 is provided inside the slot 101 corresponding to the limiting slot 45. The circuit connection of the speed band switch is existing technology and will not be described in detail.

[0031] The bottom of the limiting block 410 is provided with a compression pad 411, and the compression pad 411 contacts the contact 102. The contact at different positions corresponds to different speeds.

[0032] In this embodiment, firstly, mounting block 2 is installed on the top of housing 1, and mounting sleeve 3 is set on the top of mounting block 2. A support frame is inserted inside mounting sleeve 3. Then, adjustment mechanism 4 is inserted inside mounting sleeve 3, and the end of adjustment mechanism 4 is located inside housing 1.

[0033] Furthermore, when adjusting the band switch, first press the top of the adjustment mechanism 4, so that the spring 46 sleeved on the bottom connecting block 47 of the adjustment mechanism 4 is squeezed. Then, the limiting block 410 on the insulating disk 48 at the bottom of the connecting block 47 will disengage from the limiting opening 43 on the fixed disk 4 and be at the bottom of the fixed disk 44. At this time, the adjustment mechanism 4 is rotated. When the adjustment mechanism 4 is rotated to the appropriate position, the adjustment mechanism 4 is released. At this time, the spring 46 at the bottom of the adjustment mechanism 4 will use the restoring force to lock the limiting block 410 on the insulating disk 48 into the limiting groove 45 opened on the fixed disk 44. And the compression pad 411 at the bottom of the limiting block 410 will contact different contacts 102 in the slot 101.

[0034] Furthermore, when the adjustment mechanism 4 is rotated clockwise, the pressing pad 411 at the bottom of the limiting block 410 on the insulating disk 48 connected to the bottom connecting block 47 of the adjustment mechanism 4 will press the left contact 102. At this time, the band switch will be energized. When the adjustment mechanism 4 is rotated counterclockwise, the pressing pad 411 at the bottom of the limiting block 410 will press the contact on the other side. At this time, the band switch will be de-energized. The top of the housing 1 is marked with an indicator arrow. When the indicator arrows on the upper and lower sides are on the same axis, the pressing pad 411 and the contact 102 are pressed and contacted, which makes it easy to adjust the band switch.

[0035] After the limit is set, the connecting holes 49 on both sides of the housing 1 and the sleeve 41 are aligned on the same vertical axis. Then, the fixing structure 7 is installed in the connecting hole 49 so that the housing 1 connecting sleeve 6 can be installed stably. Then, the insulating washer 5 is set at the bottom.

[0036] In this utility model, the band switch can be speed-adjusted by the adjustment mechanism 4 at the top of the housing 1. Then, by pressing and rotating the adjustment mechanism 4, and then by the reset of the spring 46, the limiting block 410 at the bottom of the adjustment mechanism 4 contacts different contacts 102, making it more convenient to adjust the speed of the band switch.
