[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] See also Figure 1-Figure 5, which is the first embodiment of the present invention, provides a combined zipper head, including a zipper head upper piece 2 and a zipper head lower piece 1 that are opposite to each other, a sleeve 4 and a screw that splice the zipper head lower piece 1 and the zipper head upper piece 2, and the sleeve 4 and the screw cooperate to realize the splicing of the zipper head lower piece 1 and the zipper head upper piece 2. When the zipper head lower piece 1 or the zipper head upper piece 2 is damaged, it can be disassembled and replaced. Compared with replacing the entire part due to partial damage, the present application only needs to replace the damaged part, which reduces the replacement cost. A protective mechanism is provided on the zipper head upper piece 2. The structure includes a fixing hole 21 opened on the top of the zipper head upper piece 2 for the screw to pass through. When splicing, the screw is rotated through the fixing hole 21 and threaded into the sleeve 4, so that the zipper head lower piece 1 and the zipper head upper piece 2 are firmly spliced ​​together. The protective cover 5 set inside the fixing hole 21 is disassembled and assembled. When the protective cover 5 is set inside the fixing hole 21, the bottom of the protective cover 5 is against one end of the screw, and the top of the protective cover 5 is flush with the top surface of the zipper head upper piece 2. The additional protective cover 5 is used to prevent the screw from being exposed to the outside, which not only increases the appearance, but also reduces accidental injuries to users during use and increases safety in use.

[0024] In this embodiment, preferably, a groove 51 is opened on the top of the protective cover 5 to realize the opening of the groove 51, and a pull rod 6 is installed on the inner side of the groove 51 to increase the convenience of pulling up and taking down the protective cover 5.

[0025] In this embodiment, preferably, the upper portion 2 of the zipper head is provided with symmetrically distributed reinforcement heads 3 , and the reinforcement heads 3 are arc-shaped structures, so that the strength of the zipper head is increased by the arc-shaped reinforcement heads 3 .

[0026] In this embodiment, preferably, symmetrically distributed placement grooves 22 are opened inside the zipper head upper piece 2, realizing the opening of the placement grooves 22, and the connection seats 7 are installed inside the placement grooves 22, realizing the addition of the connection seats 7.

[0027] In this embodiment, preferably, symmetrically distributed fasteners 9 are provided on the connecting seat 7, thereby realizing the addition of fasteners 9, and the fasteners 9 are fixed to the inner side surface of the placement groove 22 by bolts, and the firmly installed fasteners 9 are used to increase the stability of the installation of the connecting seat 7.

[0028] In this embodiment, preferably, a accommodating groove 71 is provided inside the connecting seat 7, so that the accommodating groove 71 is opened, and a telescopic spring 710 is provided at the bottom of the accommodating groove 71, so that the telescopic spring 710 is added. One end of the telescopic spring 710 is connected to a clamping block 8, so that the clamping block 8 is added. A clamping groove 52 is provided on the outer wall of the protective cover 5, and the clamping block 8 is clamped and connected with the clamping groove 52. When the protective cover 5 is placed, the protective cover 5 is picked up and inserted into the fixing hole 21. When the protective cover 5 is inserted, the clamping block 8 is squeezed. After being squeezed, the clamping block 8 compresses the telescopic spring 710. After being compressed, the telescopic spring 710 resets, driving the clamping block 8 to be clamped in the clamping groove 52, thereby reinforcing the protective cover 5 inserted into the fixing hole 21.

[0029] Example 2

[0030] See also Figure 1-Figure 5 , which is the second embodiment of the present utility model, is based on the previous embodiment, except that:

[0031] A guide column 81 is provided on the block 8, which realizes the addition of the guide column 81. A guide sleeve 711 is provided at the bottom of the accommodating groove 71 for the guide column 81 to slide. When the block 8 moves, the guide column 81 is driven to move along the guide sleeve 711, thereby increasing the guidance of the block 8 when it moves.

[0032] The working principle and usage process of the present invention are as follows: when splicing, the screw is rotated through the fixing hole 21 and is threadedly connected in the sleeve 4, so that the zipper head lower piece 1 and the zipper head upper piece 2 are firmly spliced. When the protective cover 5 is placed, the protective cover 5 is picked up and inserted into the fixing hole 21. When the protective cover 5 is inserted, the card block 8 is squeezed. After being squeezed, the card block 8 compresses the telescopic spring 710. The telescopic spring 710 is reset after being compressed, driving the card block 8 to be clamped in the card slot 52, thereby reinforcing the protective cover 5 inserted into the fixing hole 21. The additional protective cover 5 is used to avoid the screws from being exposed to the outside, which increases the appearance while reducing accidental injuries to users during use and increases safety in use.
