The first housing 111 serves as the bottom housing, and a control module insertion portion 12, a first insertion portion 141, and a second insertion portion 142 are provided on the first housing 111. The second housing 112 is disposed on the top of the first housing 111, and an avoidance opening for avoiding the control module insertion portion 12 is provided on the second housing 112, facilitating the insertion of the control module. Dividing the main body portion 11 into the first housing 111 and the second housing 112 is more convenient for installing the first housing 111, the second housing 112, and the control module compared to integrally forming, and is more conducive to the expansion of the main body portion 11.

[0050] According to some embodiments of the present utility model, a first engaging member 16 and a second engaging member are provided on the second housing 112. The first engaging member 16 is provided on one side in the length direction of the control module insertion portion 12, the second engaging member is provided on the other side in the length direction of the control module insertion portion 12.

[0053] like Figure 3 As shown, a toggle surface 163 is formed on the first clamping member 16, and the toggle surface 163 is constructed as an inclined surface away from the second shell 112. When the control module is connected to the second shell 112, the toggle surface 163 can avoid the control module, which makes the installation of the control module more convenient. The first clamping member 16 can be deformed by applying force to the toggle surface 163, which makes it more convenient to clamp the control module with the second clamping hole 162. By deforming the first fixing member, it is also easier to separate the second shell 112 from the control module, and the disassembly and assembly of the control module is more convenient.

[0054] According to some embodiments of the present invention, a clamping groove 17 suitable for accommodating an external guide rail is provided on a side of the first shell 111 facing away from the second shell 112 , and a clamping wall 171 suitable for clamping with an edge of the external guide rail is provided in the clamping groove 17 .

[0055] Specifically, a snap-in groove 17 is provided on the first shell 111. The first shell 111 can be sleeved on the outer periphery of the external guide rail through the snap-in groove 17, and snap-fit ​​with the edge of the external guide rail through a snap-in wall 171 provided in the snap-in groove 17 to achieve connection with the external guide rail. The second shell 112 and the control module cooperate with the first shell 111 to achieve installation of the control module on the external guide rail.

[0056] According to some embodiments of the present invention, the first shell 111 is further provided with a clamping track 18 connected to the clamping slot 17, and a clamping pin 19 is movably provided in the clamping track 18. The clamping pin 19 can be selectively moved toward the clamping slot 17 to lock with the external guide rail.

[0057] Specifically, a clamping track 18 communicating with the clamping groove 17 is further provided on the first housing 111. A clamping pin 19 is movably arranged in the clamping track 18. By moving the clamping pin 19, the clamping pin 19 can be locked with an external guide rail to prevent the external guide rail from disengaging from the clamping groove 17, ensuring the stable installation of the control module and the main body 11 on the external guide rail. By moving the clamping pin 19 away from the clamping groove 17, the restriction on the external guide rail can be released, facilitating the disassembly of the main body 11.

[0058] According to some embodiments of the present invention, a clamping block 181 is arranged in the clamping track 18. A receiving groove for receiving the clamping block 181 is formed on the clamping pin 19. A first engaging portion 191 and a second engaging portion 192 are formed in the receiving groove. When the clamping pin 19 moves towards the clamping groove 17 and is locked with the external guide rail, the first engaging portion 191 is engaged with the outer periphery of the clamping projection. The second engaging portion 192 is adapted to abut against the clamping projection to limit the clamping pin 19 from disengaging from the clamping track 18.

[0059] Specifically, a clamping block 181 is arranged in the clamping track 18. When the clamping pin 19 moves in the clamping track 18, the clamping block 181 will enter and stay in the receiving groove. A first engaging portion 191 and a second engaging portion 192 are formed in the receiving groove. The first engaging portion 191 can be configured as Figures 6 to 8 the clamping claw shown. When the clamping pin 19 moves towards the clamping groove 17 and is locked with the external guide rail, the inner peripheral wall of the clamping claw abuts against the outer peripheral wall of the clamping block 181 to lock the clamping pin 19 with the clamping track 18, preventing the clamping pin 19 from releasing the lock with the external guide rail. When it is necessary to remove the main body 11, the clamping pin 19 is pushed to move away from the clamping groove 17 to release the lock between the clamping pin 19 and the external guide rail. When the clamping pin 19 moves to the position where the second engaging portion 192 abuts against the clamping block 181, the clamping hole restricts the clamping pin 19 from disengaging from the clamping track 18, preventing the clamping pin 19 from falling off and extending the service life of the clamping pin 19.
