[0033] When this embodiment is used, the drill rod is inserted between the first clamping groove 11 and the second clamping groove 21, and the distance between the drill rod and the wall to be drilled is adjusted, and the horizontal and longitudinal distances between the first anchor rod 5 and the second anchor rod 6 corresponding to the supporting anchor rod, and then the upper and lower first fastening blocks 13 and the second fastening blocks 23 are tightened by screwing the screw 7, so that the drill rod is fixed between the first clamping groove 11 and the second clamping groove 21, and the first anchor rod 5 and the second anchor rod 6 are respectively fixed between the first fixed slider 3 and the second fixed slider 4. The drilling work can be started; the present invention has a simple structure and strong practicality, and the fixed rod, the anchor rod and the fixed slider can be set to a movable and adjustable connection. The use can adjust the longitudinal angle between the fixed rod and the anchor rod according to the structure of the anchor rod support, and solve the problem that the drill rod deviates from the designed orientation and inclination due to instability and difficulty in control during drilling, and greatly reduce the wear of the drill bit; and the operation is simple, the adaptability is strong, and it is suitable for all anchor rod support tunnels.

[0034] In this embodiment, the first fixing rod 12 is inserted into the fixing slide block 3 through a first through hole 31 provided on the first fixing slide block 3; the second fixing rod 22 is inserted into the second fixing slide block 4 through a second through hole 41 provided on the second fixing slide block 4;

[0035] The first fixed slider 3 and the second fixed slider 4 are respectively provided with a third through hole 32 and a fourth through hole 42 which are axially perpendicular to the first through hole 31 and the second through hole 41, and the first anchor fixing rod 5 and the second anchor fixing rod 6 are respectively passed through the third through hole 32 and the fourth through hole 42;

[0036] The first anchor rod 5 and the second anchor rod 6 respectively include a support rod 9 and an anchor rod cap 10 arranged at the top end of one side of the support rod 9. The anchor rod cap 10 is set to be cylindrical or square according to needs.

[0037] The first fixed slider 3 is provided with a first threaded hole and a second threaded hole which are axially perpendicular to and communicate with the first through hole 31 and the third through hole 32, respectively. The first threaded hole and the second threaded hole are adapted with fastening bolts 8. The fastening bolts 8 fix the first fixed slider 3 to the first fixing rod 12 through the first threaded hole, and the fastening bolts 8 fix the first anchor fixing rod 5 to the first fixed slider 3 through the second threaded hole.

[0038] Similarly, the second fixed slider 4 is respectively provided with a third threaded hole and a fourth threaded hole which are axially perpendicular to and connected to the second through hole 41 and the fourth through hole 42. The third threaded hole and the fourth threaded hole are adapted with fastening bolts 8. The fastening bolts 8 fix the second fixed slider 4 to the second fixed rod 22 through the third threaded hole. The fastening bolts 8 fix the second anchor fixing rod 6 to the second fixed slider 4 through the third threaded hole.

[0039] It should be noted that the present embodiment is not limited to only setting a first fixed slider 3 and a second fixed slider 4. According to the structure of the coal mine shaft and the structure of the anchor support, multiple fixed sliders can be symmetrically or asymmetrically set on the first fixed rod 12 and the second fixed rod 22 to fix the anchor fixing rod on the side support anchor rod, so that the clamp of the present embodiment has better fixation and stability.

[0040] Preferably, in this embodiment, an anti-wear lining is provided between the drilling drill rod and the first clamping groove 11 and the second clamping groove 21 .

[0041] The working principle of the present invention is as follows:

[0042] Insert the drill rod between the first clamping groove 11 and the second clamping groove 21, and then pass the ends of the support rod 9 of the first anchor fixing rod 5 and the second anchor fixing rod 6 through the third through hole 32 and the fourth through hole 42, adjust the distance of the drill rod to the wall surface to be drilled, and the lateral and longitudinal distances of the first anchor fixing rod 5 and the second anchor fixing rod 6 corresponding to the helper support anchor rod, and then tighten the upper and lower first fastening blocks 13 and the second fastening blocks 23 by screwing the screw 7, so that the drill rod is fixedly set between the first clamping groove 11 and the second clamping groove 21; screw the fastening bolt 8 to fix the first fixed slider 3 and the first fixed rod 12 and the first anchor fixing rod 5, and screw the fastening bolt 8 to fix the second fixed slider 4 and the second fixed rod 22 and the second anchor fixing rod 6; after the fixing is completed, the drilling work can be started; the present invention has a simple structure and strong practicality. It not only solves the problem that the opening of the hole deviates from the designed azimuth and inclination angle due to the instability and difficulty in control of the drill rod during drilling, but also greatly reduces the wear of the drill bit; it is simple to operate and has strong adaptability, and is suitable for all anchor support tunnels.

[0043] This embodiment is preferred, as Figure 3 As shown, in order to make the anchor cap 10 and the supporting anchor better fit and fix, the end face of the anchor cap 10 is provided with a "M-shaped" groove 101 that matches the shape of the supporting anchor; for example, if the supporting anchor is cylindrical, the end face groove 101 of the anchor cap 10 is an arc shape, and if the supporting anchor is a quadrangular prism, the end face 101 of the anchor cap 10 is a right-angle groove.

[0044] This embodiment is preferred, as Figure 4 As shown, in order to make the connection between the anchor rod and the fixed slider more stable, and to avoid the anchor rod sliding in the through hole during operation due to the frequent friction between the anchor rod and the fastening bolt 8 after long-term use, the following are specifically made:

[0045] A plurality of continuous fixing slots 91 are arranged on the outer side surfaces of the support rods 9 of the first anchor fixing rod 5 and the second anchor fixing rod 6. The size of the fixing slots 91 is adapted to the screw diameter of the fastening bolt 8. With this structural arrangement, the support rod 9 is inserted into the third through hole 32, the lateral and longitudinal distances between the first anchor fixing rod 5 and the auxiliary support anchor rod are adjusted, and the fastening bolt 8 is screwed to adjust the support rod 9 so that the fastening bolt 8 is inserted into the fixing slot 91. The arrangement of the second anchor fixing rod 6 is also based on the same principle as above.

[0046] Preferably, in this embodiment, the support rod 9 and the anchor cap 10 of the first anchor fixing rod 5 and the second anchor fixing rod 6 are detachably connected, which can be a threaded or plug-in connection. When using the clamp, this structure first fixes the drill rod and the first clamping component 1 and the second clamping component 2, and then separates the support rod 9 and the anchor cap 10 respectively. The support rod 9 is passed through the third through hole 32 and the fourth through hole 42 from the back to the front respectively, and then the anchor cap 10 is connected to the end of the support rod 9. In this way, when the user operates, there is no need to adjust the drill rod, the first anchor fixing rod 5 and the second anchor fixing rod 6 with the clamping components and the fixing block at the same time because the support rod 9 and the anchor cap 10 are integrated, which makes it more convenient and simple to use.

[0047] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware that any structural changes made under the inspiration of the present invention, and any technical solutions that are the same or similar to the present invention, fall within the protection scope of the present invention.
