Preferably, the diameter of the clamping hole is larger than the male diameter of the threaded hole.
Preferably, the anti-slip pad is made of rubber.
The beneficial effects of the utility model are as follows:
1. when the anti-slip device is used, the connection stability between the anchor rod sleeve and the anchor rod can be more effectively improved, the anchor rod is prevented from moving relatively to the anchor rod, the anchor rod is screwed into the threaded hole of the anchor rod sleeve body, then the jackscrew is rotated, the jackscrew is propped against the anchor rod through the anti-slip pad to limit the position of the anchor rod, the anchor rod is prevented from rotating in the anchor rod sleeve body to loosen the connection relation between the anchor rod and the anchor rod sleeve body, the anti-slip pad plays a role in protecting the external threads of the anchor rod, the jackscrew is prevented from directly contacting the anchor rod to damage the threads of the anchor rod, and the connection stability between the anchor rod sleeve and the anchor rod is improved.

Fig. 2 is a schematic cross-sectional structure of the anchor rod sleeve body of the present utility model.
Fig. 3 is a schematic diagram of the structure of fig. 2 a according to the present utility model.
In the figure: 1. an anchor rod sleeve body; 2. a threaded hole; 3. a clamping hole; 4. a jackscrew mounting hole; 5. a jackscrew; 6. an anti-slip mat.
Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings.
As shown in fig. 1 to 3, an anchor rod sleeve comprises an anchor rod sleeve body 1, wherein a threaded hole 2 is formed in the inner wall of the anchor rod sleeve body 1, clamping holes 3 are formed in two ends of the anchor rod sleeve body 1, the clamping holes 3 are identical to the axes of the threaded holes 2, a plurality of groups of jackscrew mounting holes 4 are formed in two ends of the outer surface of the anchor rod sleeve body 1 in a penetrating mode, the jackscrew mounting holes 4 penetrate into the clamping holes 3, jackscrews 5 used for supporting the outer surface of an anchor rod to prevent the anchor rod from rotating are mounted on the inner wall of the jackscrew mounting holes 4 in a meshed mode, and an anti-slip pad 6 used for improving the fastening effect of the jackscrews 5 on the anchor rod is mounted at one end, in contact with the outer surface of the anchor rod, of the jackscrews 5.
When the fixed effect between anchor rod sleeve and stock needs to be promoted, screw in the screw hole 2 of anchor rod sleeve body 1 with the stock, rotate jackscrew 5 this moment, jackscrew 5 withstands the stock through slipmat 6 spacing, prevent that the stock from taking place to rotate in anchor rod sleeve body 1 and leading to the relation of connection between stock and the stock sleeve body 1 not hard up, and slipmat 6 plays the guard action to the external screw thread of stock, has prevented that jackscrew 5 is direct with the screw thread of stock contact destruction stock, has promoted the connection stability between stock sleeve and the stock, prevents not hard up between stock sleeve and the stock.
Specifically, the diameter of the clamping hole 3 is larger than the male diameter of the threaded hole 2.
Specifically, the anti-slip pad 6 is made of rubber.
Working principle: when the novel anchor rod is used, an anchor rod is screwed into the threaded hole 2 of the anchor rod sleeve body 1, then the jackscrew 5 is rotated to enable the jackscrew 5 to prop against the anchor rod, the anchor rod is prevented from rotating in the anchor rod sleeve body 1, the connection stability between the anchor rod sleeve and the anchor rod is affected, and looseness between the anchor rod sleeve and the anchor rod is prevented.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
