[0033] Please refer to Figures 1 to 6 :

[0034] Example 1:

[0035] This utility model proposes a quick-positioning anchor bolt installer for coal mine geological roadway support, comprising: a connecting rod 1, with an installation joint 2 fixedly installed at the bottom end of the connecting rod 1; a contraction cavity 6 opened at the bottom end of the installation joint 2; a fixing docking piece 8 fixedly installed at the bottom end inside the contraction cavity 6; a hexagonal fixing docking groove opened at the center position of the fixing docking piece 8; a docking slide plate A9 slidably installed inside the contraction cavity 6; a hexagonal docking slider A10 fixedly installed at the bottom end of the docking slide plate A9; and a hexagonal docking slide groove opened at the bottom end of the docking slider A10. Hole A11; A docking slide plate B13 is slidably installed at the top of the inner cavity 6; A hexagonal docking slider B14 is fixedly installed at the bottom of the docking slide plate B13; A docking sliding hole B15 is opened at the bottom of the docking slider B14. With the docking slider A10 and docking slider B14 set on the basis of the fixed docking part 8, this installer has three sizes of threaded interfaces: fixed docking groove, docking sliding hole A11 and docking sliding hole B15. This makes it easy for this installer to be used for the installation of more sizes of screws, and improves the flexibility and versatility of this anchor bolt installer.

[0036] In Example 2, based on Example 1, two switching guide grooves 3 are provided on the outer circumference of the mounting connector 2; a switching slide groove 4 is provided inside each of the two switching guide grooves 3; a switching slot 5 is provided at both ends of each of the two switching slide grooves 4; the diameter of the switching slot 5 is larger than the width of the switching slide groove 4; an embedded protrusion 7 is provided on the inner circumference of the shrinking cavity 6; the shape of the docking slider A10 matches the shape of the fixed docking groove on the fixed docking part 8; the docking slide hole A11 passes through the top of the docking slide plate A9; the top of the docking slide plate A9 and the bottom of the embedded protrusion 7 are both fitted with a spring A12; the shape of the docking slider B14 matches the shape of the docking slide hole A11. A quick positioning structure is formed by the limiting clip 21, the U-shaped pull ring 20 and the guide slide rod 17, etc. This structure can quickly and conveniently adjust and lock the docking slide hole of the required size in the state of use, improving the convenience of the installer when changing the size.

[0037] In Example 3, based on Example 2, a mounting groove is provided on the top of the docking slide B13, and a spring B16 is mounted between the bottom end of the mounting groove and the top end of the inner cavity 6; a limiting slot 19 is provided on the right side of both the docking slide A9 and the docking slide B13; a guide slide rod 17 is fixedly installed in the center of the two limiting slots 19; the two guide slide rods 17 are slidably installed in the two switching slides 4 respectively; a mounting plate 18 is fixedly installed on the outer end of the guide slide rod 17; a U-shaped pull ring 20 is slidably installed on the mounting plate 18; a limiting clip 21 is fixedly installed on the inner end of the U-shaped pull ring 20; the inner end of the limiting clip 21 is engaged in the inner end of the limiting slot 19; A spring C22 is embedded between the outer wall of the limiting clip 21 and the inner wall of the mounting plate 18. When the docking slider A10 needs to be put into use, it is only necessary to manually pull the corresponding U-shaped pull ring 20 outward first, so that it takes the limiting clip 21 out of the upper limit slot 19 and the corresponding switching slot 5 of the docking slide A9. At this time, the docking slide A9 will move downward under the action of the spring A12 until the docking slide hole A11 moves to the use state. At this time, the outward pull of the U-shaped pull ring 20 is released, so that it takes the limiting clip 21 back into the limiting slot 19 under the action of the spring C22, and the docking slide hole A11 is positioned in the use state, which is convenient for the installation of anchor rods of appropriate size.

[0038] The working principle of this embodiment is as follows: When the docking slider A10 needs to be put into use, it is only necessary to manually pull the corresponding U-shaped pull ring 20 outward first, so that it, along with the limiting clip 21, disengages from the upper limit clip groove 19 and the corresponding switching clip 5 of the docking slide plate A9. At this time, the docking slide plate A9 will move downward under the action of the spring A12 until the docking slide hole A11 moves to the use state. Then, release the outward pull of the U-shaped pull ring 20, so that it, along with the limiting clip 21, re-enters the limiting clip groove 19 under the action of the spring C22, positioning the docking slide hole A11 in the use state, which is convenient for installing anchor rods of appropriate size. To put the docking slider B14 into the use state, the above corresponding steps can be repeated.

[0039] The following points should be noted in this article:

[0040] 1. The accompanying drawings of the embodiments disclosed herein only relate to the structures involved in the embodiments disclosed herein; other structures can be referred to in general design.

[0041] 2. Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.

[0042] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
