The side wall of the makeshift groove 12 is provided with a movable guide groove 13. The end of the movable guide groove 13 is provided with a frame 4. The frame 4 is provided with a concave cavity 41. The concave cavity 41 is provided with a movable button 5. When the protrusion 21 enters the makeshift groove 12, the contact box 2 is rotated to make the protrusion 21 move along the direction of the movable guide groove 13, so that the fixing component 3 enters the concave cavity 41 and moves upward against the button 5, so that the contact box 2 is connected and fixed to the mounting base 1.

[0028] It is worth mentioning that the convex block 21 is provided with a first blind hole 22, the first blind hole 22 is provided with a first through hole 23, the bottom of the convex block 21 is provided with a bottom cover 24, the bottom cover 24 is provided with a first countersunk hole 25, the first blind hole 22 provides a guide for the movable column 32, the first through hole 23 facilitates the fixed column 33 to protrude from the surface of the convex block 21, the bottom cover 24 provides support for the spring 31, and the first countersunk hole 25 increases the spacing with the second countersunk hole 34 to prevent the spring 31 from being compressed, resulting in a large amount of compression, thereby reducing the elastic potential energy of the spring 31;

[0029] It is worth mentioning that the fixing assembly 3 includes a spring 31 and a movable column 32. The movable column 32 is arranged in the first blind hole 22. The movable column 32 is provided with a fixed column 33. The movable column 32 is provided with a second countersunk hole 34. The spring 31 abuts against the first countersunk hole 25 and the second countersunk hole 34, so that the movable column 32 passes through the first through hole 23 and protrudes from the surface of the protrusion 21. The shape of the end face of the fixed column 33 is set to be hemispherical. The first countersunk hole 25 and the second countersunk hole 34 also play a role in preventing the spring 31 from detaching. The movable column 32 plays a role in limiting the height of the fixed column 33 protruding from the surface of the protrusion 21. The fixed column 33 is used in conjunction with the concave cavity 41. The hemispherical design reduces the friction between the fixed column 33 and the guide groove 134, so that the fixed column 33 can be smoothly retracted into the first blind hole 22.

[0030] It is worth mentioning that a second through hole 131 is provided at the top of the end of the movable guide groove 13, and avoidance grooves 132 are provided on both sides of the second through hole 131. The avoidance groove 132 is provided with a threaded hole 133. A guide groove 134 is provided at the entrance of the movable guide groove 13. The shape of the guide groove 134 is set to an oblique triangle. The two through holes are convenient for accommodating the function of the frame 4. The avoidance groove 132 makes the frame 4 flush with the surface of the fixed base. The threaded hole 133 is used in conjunction with the fastening screw 43. The oblique triangle design of the guide groove 134 allows the fixing column 33 to gradually retract to the first blind hole 22 as the moving distance of the contact box 2 increases;

[0031] It is worth mentioning that the frame 4 is arranged in the second through hole 131, and the frame 4 is provided with a mounting hole 42 corresponding to the threaded hole 133, and the mounting hole 42 is provided with a fastening screw 43, so that the frame 4 is connected and fixed with the avoidance groove 132, and the frame 4 is provided with at least two first magnets 44, and the mounting hole is used in conjunction with the fastening screw 43, and the frame 4 provides support for the button 5, and the first magnet 44 is used in conjunction with the second magnet 51;

[0032] It is worth mentioning that both end surfaces of the cavity 41 are provided with through holes 45, which facilitate the fixing column 33 to enter the cavity 41 and also provide a guide for the button 5;

[0033] It is worth mentioning that the button 5 is arranged in the through hole 45, the head of the button 5 is provided with a second magnet 51 corresponding to the first magnet 44, the button 5 is provided with a retaining ring 52, and is arranged in the concave cavity 41, and the head of the button 5 is also provided with a reset mark arrow 53, the hole provides a guide for the button 5, the retaining ring 52 limits the upward movement distance of the button 5, and the reset mark arrow 53 facilitates the user to unlock the contact box 2 and the mounting base 1;

[0034] It is worth mentioning that the number of the protrusions 21 and the clearance grooves 12 is set to at least two, and the number setting is the minimum setting to ensure reliable connection.

[0035] The use principle of the utility model is now described as follows:

[0036] Align the protrusion 21 with the yield groove 12, so that the contact box 2 enters the fixed blind hole 11, rotate the contact box 2, so that the protrusion 21 moves along the direction of the movable guide groove 13, and the fixed column 33 enters the guide groove 134. As the movable distance of the protrusion 21 increases, the fixed column 33 gradually retracts into the first blind hole 22, and compresses the spring 31 to store energy in the spring 31. When the first through hole 23 and the through hole 45 are on the same axis, the spring 31 releases the reaction force to push the fixed column 33 through the first through hole 23 and the through hole 45, and enter the concave cavity 41, and push the button 5 to move upward, so that the retaining ring 52 abuts against the end surface of the concave cavity 41. This design can remind the user that the contact box 2 is connected and fixed to the mounting base 1;

[0037] When the contact box 2 needs to be separated from the mounting base 1, a downward pressure is applied to the button 5, and the button 5 pushes the fixing column 33 to retract into the first blind hole 22, so that the second magnet 51 attracts the first magnet 44, ensuring that all the fixing columns 33 on the contact box 2 are retracted into the first blind hole 22, and the contact box 2 and the mounting base 1 are unlocked. At this time, the contact box 2 is rotated in the opposite direction, so that the protrusion 21 returns to the yield groove 12 along the movable guide groove 13, and the contact box 2 can be separated from the mounting base 1;

[0038] The button 5 is rotated to make the second magnet 51 and the first magnet 44 form a dislocation relationship, so as to prepare for the next connection and fixation of the contact box 2 and the mounting base 1.

[0039] The above design scheme can enable the product to achieve the advantages of easy disassembly and assembly and reliable connection.

[0040] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
