[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-2 , is the first embodiment of the utility model, which provides a blasting tube fixing device for blasting, comprising:

[0031] The fixing assembly 100 includes a connecting tube 101, an extrusion tube 102 threadedly connected to the inner wall of the connecting tube 101, a fixing ring 105 connected to the inner wall of the connecting tube 101, an inclined plate 106 connected to one side of the fixing ring 105, and an inclined block 107 connected to one side of the inclined plate 106, wherein the diameter of the fixing ring 105 is greater than or equal to the diameter of the blasting tube;

[0032] There are four inclined plates 106 , with gaps between the four inclined plates 106 , and the four inclined plates 106 are distributed in a conical shape;

[0033] The number of the inclined blocks 107 is the same as the number of the inclined plates 106 , and there are gaps between the four inclined blocks 107 . The difference is that the outer diameter of the inclined block 107 is larger than the outer diameter of the inclined plate 106 , and the cross-sectional shape of the inclined block 107 is a trapezoid.

[0034] A rotating handle 103 is provided on one side of the extrusion tube 102, and an arc-shaped extrusion channel 104 is provided on one side of the extrusion tube 102, wherein the cross-sectional shape of the extrusion channel 104 is conical, and the diameter of the side of the extrusion channel 104 close to the inclined block 107 is larger than the maximum diameter of the inclined block 107, while the diameter of the side of the extrusion channel 104 away from the inclined block 107 is smaller than the inclined block 107.

[0035] One side of the inclined block 107 contacts one side of the extrusion channel 104, and the outer wall of the inclined block 107 is slidably connected to the inner wall of the connecting tube 101. When the extrusion channel 104 moves toward the inclined block 107, the inclined block 107 will be squeezed, so that the inclined block 107 and the inclined plate 106 gradually move closer to the blasting tube, thereby clamping the blasting tube.

[0036] In summary, when placing the blasting tube, pass the blasting tube through the connecting tube 101, then hold the connecting tube 101 and choose to turn the handle 103 to make the squeezing tube 102 move toward the inclined block 107. At this time, the squeezing channel 104 will gradually squeeze the inclined block 107 and the inclined plate 106, so that the inclined plate 106 will clamp the blasting tube, and the connecting tube 101 can expand the diameter of the blasting tube, so that the blasting tube can fit the blasting hole better when entering the blasting hole. At the same time, the threads set on the connecting tube 101 and the anti-slip patterns set on the rotating handle 103 can also increase the friction with the blasting hole to prevent the blasting tube from easily detaching from the blasting hole.

[0037] Example 2

[0038] Reference Figure 1 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0039] The outer wall of the connecting pipe 101 is connected with a positioning assembly 200, which includes a connecting page 201 connected to one side of the connecting pipe 101, a linkage ring 202 threadedly connected to the outer wall of the connecting pipe 101, a guide plate 208 connected to one side of the connecting page 201, and an extrusion ring 206 in contact with one side of the guide plate 208, wherein there are four connecting pages 201, gaps are left between the four connecting pages 201, and the four connecting pages 201 are surrounded in a circle;

[0040] The number and distribution of the guide plates 208 are the same as those of the connecting page 201 , except that the guide plates 208 have an arc, and the four guide plates 208 are cylindrical and surround.

[0041] A sliding groove 203 is provided on the inner wall of the linkage ring 202. The sliding groove 203 is circular. A sliding block 204 is slidably connected to the inner wall of the sliding groove 203. The thickness of the linkage ring 202 where the sliding groove 203 is provided is greater than the thickness of other regions.

[0042] One side of the sliding block 204 is connected to a connecting rod 205 , and the other side of the connecting rod 205 is connected to the outer wall of the extrusion ring 206 , wherein the sliding block 204 and the connecting rod 205 are perpendicular to each other, and the side of the connecting rod 205 connected to the sliding block 204 is slidably connected to the inner wall of the linkage ring 202 .

[0043] The outer wall of the connecting rod 205 is slidably connected to the inner wall of the connecting page 201, and the outer wall of the linkage ring 202 is connected with a positioning groove 207. A 90-degree bend is set on the side of the connecting rod 205 close to the extrusion ring 206. This area is located between the two connecting pages 201, so the overall movement direction of the connecting rod 205 is limited by the connecting page 201.

[0044] One side of the connecting rod 205 is slidably connected to the outer wall of the connecting tube 101. The extrusion ring 206 is annular in shape. The width of the extrusion ring 206 is greater than the width of the guide plate 208. When the extrusion ring 206 moves toward the guide plate 208, the extrusion ring 206 will squeeze the guide plate 208. Since the guide plate 208 is distributed in a conical shape, when the extrusion ring 206 squeezes the guide plate 208, the guide plate 208 can expand away from the direction of the blasting tube, thereby increasing the diameter of the overall device.

[0045] Here, the connection page 201 and the guide plate 208 are both made of aluminum alloy.

[0046] In summary, after the connecting tube 101 is fixed to the blasting tube, the linkage ring 202 is rotated to move the linkage ring 202 in the direction of the rotating handle 103, and the linkage ring 202 will drive the connecting rod 205 and the squeezing ring 206 to move in the direction of the guide plate 208. At this time, the squeezing ring 206 will squeeze the guide plate 208 to expand the guide plate 208, so that the guide plate 208 and the connecting leaf 201 are expanded to a diameter close to that of the blasting hole, and then the blasting tube and the overall device are placed in the blasting hole, which greatly increases the friction between the overall device and the blasting hole, thereby preventing the blasting tube from being affected by the explosion of other blasting tubes and ejecting out of the blasting hole during detonation.

[0047] Example 3

[0048] Reference Figure 1 to Figure 7 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment, except that,

[0049] The outer wall of the positioning groove 207 is connected with a rotating assembly 300, which includes a sleeve 301, a push rod 302 connected to one side of the sleeve 301, and a placement groove 303 opened on one side of the sleeve 301. When the blasting tube and the whole device are not in use, the blasting tube and part of the whole device can be placed in the placement groove 303, and the sleeve 301 can protect the blasting tube and part of the whole device.

[0050] There are two push rods 302 , and the two push rods 302 are respectively located on two sides of the sleeve 301 .

[0051] One side of the push rod 302 is engaged with one side of the positioning groove 207. The diameter of the placement groove 303 is larger than the diameter of the connecting tube 101. The push rod 302 can slide into the positioning groove 207. By rotating the sleeve 301, the positioning groove 207 and the linkage ring 202 can be driven to rotate.

[0052] In summary, when the diameter of the blasting hole is large, first rotate the linkage ring 202 to expand the guide plate 208 and the connecting page 201 to a diameter close to the blasting hole, so that the guide plate 208 and the connecting page 201 are difficult to rotate in the blasting hole, and then place the blasting tube and the overall device into the blasting hole, and then slide the push rod 302 into the positioning groove 207. At this time, rotate the sleeve 301 to allow the guide plate 208 and the connecting page 201 to continue to expand. At this time, the guide plate 208 and the connecting page 201 will squeeze the blasting hole, so that the blasting tube is completely fixed in the blasting hole, further preventing the blasting tube from escaping from the blasting hole.
