[0002] In order to achieve the purpose of saving detonator to reduce cost in the process of tunnel construction, a method of "cluster connection" is used. Cluster connection, commonly known as "one-handed", binds the detonator in the middle of the detonating cord, triggers the detonator, and initiates the detonating cord to the surrounding hole. At this time, the artificial operation is to wrap several detonating cords and detonators together for transmission by using adhesive tape. Often, the detonating cord is on one side or overlaps, and the detonator is on the other side instead of being in the middle of the detonating cord, resulting in some detonators and detonating cords cannot transmit normally and cause underbreak, which greatly affects the construction efficiency. Therefore, it is necessary to design a portable cluster continuous fixed device to solve the above problems. SUMMARY

[0003] The technical problem to be solved by the utility model is that the existing device lacks a fixed position device and a concentrating device for the detonating cord, which can easily cause related underbreak problems caused by abnormal transmission of cluster connection during blasting.

The concentrating device comprises a sleeve upper part and a sleeve lower part, and the sleeve upper part and the sleeve lower part are connected by the buckle restraint device. The detonating cord fixing device is connected above the sleeve upper part, and the elastic buckle tightening device is connected below the sleeve lower part.

The detonating cord fixing plate is fixedly arranged above the sleeve upper part. The detonating cord special holes are evenly arranged in a circular shape on the detonating cord fixing plate, and the detonating cord special holes are in communication with the sleeve upper part.

[0006] As an improvement, the buckle restraint device comprises an embedded slot and an embedded buckle. The embedded buckle is inserted into the embedded slot, and the embedded slot is fixedly arranged between the sleeve upper part and the sleeve lower part.

[0007] As an improvement, the elastic buckle tightening device comprises a fixed elastic buckle and a movable elastic buckle. The fixed elastic buckle is fixedly arranged below the sleeve lower part, and the movable elastic buckle corresponds to the fixed elastic buckle. The fixed elastic buckle and the movable elastic buckle form a detonator special hole.
