Since the plug rod 19 is inserted into the slot of the first swing arm 17, the first swing arm 17 and the second swing arm 18 can be directly separated, thereby avoiding the disassembly of the bracket 21 while playing a supporting role.

[0031] A rubber pad 20 is provided at the bottom of the chassis body 1. The provision of the rubber pad 20 can increase the friction force at the bottom of the chassis body 1, so that the chassis body 1 can be placed more stably to avoid displacement.

[0032] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a chassis fan that is easy to adjust the angle provided by this embodiment is as follows:

[0033] The driving motor 5 is started to drive the first gear 6 to rotate. Since the first gear 6 and the second gear 7 are meshed and connected, the second gear 7 rotates accordingly. The connecting rod 8 can drive the bracket 21 to rotate through the fixing plate 12 under the drive of the second gear 7, thereby completing the adjustment of the angle of the fan body 2, which can increase its heat dissipation range and make the heat dissipation effect better. The connecting rod 8 and the fixing plate 12 are connected by the engagement of the clamping block 11 and the groove 13. By pulling the bracket 21 upward, the fixing plate 12 squeezes and contracts the clamping block 11 into the concave hole 9. After the clamping block 11 is separated from the groove 13, the fan body 2 can be removed from the fixing plate 12. During installation, the connecting rod 8 is inserted into the fixing plate 12.

The bolts 15 can fasten multiple fan bodies 2 to the bracket 21 to prevent the fan body 2 from falling off. When the fan body 2 is adjusted, the first swing arm 17 and the second swing arm 18 swing along under the action of the movable block 16 and the insertion rod 19, which can support the bracket 21 and prevent the bracket 21 from shaking when rotating. Since the insertion rod 19 is inserted into the notch of the first swing arm 17, the first swing arm 17 and the second swing arm 18 can be directly separated, thereby avoiding the disassembly of the bracket 21 while playing a supporting role. The rubber pad 20 can increase the friction at the bottom of the chassis body 1, so that the chassis body 1 can be placed more stably to avoid displacement.

[0034] In summary, in the present embodiment, according to the present embodiment, a chassis fan that is easy to adjust the angle is provided. Through the arrangement of the concave hole 9, the spring 10, the block 11 and the fixing plate 12, the connecting rod 8 and the fixing plate 12 are connected by the engagement of the block 11 and the groove 13. By pulling the bracket 21 upward, the fixing plate 12 squeezes and contracts the block 11 into the concave hole 9. After the block 11 is disengaged from the groove 13, the fan body 2 can be removed from the fixing plate 12. During installation, the connecting rod 8 is inserted into the fixing plate 12. The block 11 engages with the groove 13 under the reset of the spring 10, which facilitates the disassembly and installation of the fan body 2. By providing one end of the block 11 as an arc, the friction force on the surface of the block 11 is reduced, making it easier to slide in the groove 13, which facilitates installation and disassembly. The fan body 2 can be adjusted by the arrangement of the control panel 14. When the fan body 2 is adjusted, it is convenient to start the driving motor 5. Through the setting of the bolts 15, multiple fan bodies 2 can be fastened to the bracket 21 to prevent the fan body 2 from falling off. Through the setting of the movable block 16, the first swing arm 17, the second swing arm 18 and the insertion rod 19, when the fan body 2 is adjusted, the first swing arm 17 and the second swing arm 18 follow the swing under the action of the movable block 16 and the insertion rod 19, which can support the bracket 21 and prevent the bracket 21 from shaking when rotating. Since the insertion rod 19 is inserted into the groove of the first swing arm 17, the first swing arm 17 and the second swing arm 18 can be directly separated, so that the bracket 21 can be avoided from being disassembled while playing a supporting role. Through the setting of the rubber pad 20, the friction at the bottom of the chassis body 1 can be increased, and the chassis body 1 can be placed more stably to avoid displacement.
