[0036] The ejection block 301 is embedded in the embedding hole 101 opened on the top side of the tooling base 1; the arc plate 302 is fixed at one end of the top side of the ejection block 301; the pressing plate 303 is fixed at the top of the arc plate 302; the telescopic rod body 304 is arranged between the bottom side of the pressing plate 303 and the top side of the tooling base 1, and the two ends of the telescopic rod body 304 are respectively connected to the bottom side of the pressing plate 303 and the top side of the tooling base 1; the spring 305 is sleeved on the telescopic rod body 304, and the two ends of the spring 305 are respectively fixedly connected to the bottom side of the pressing plate 303 and the top side of the tooling base 1, and the elastic coefficient of the spring 305 is selected and used by the technicians in this profession according to actual conditions.

[0037] The utility model has the advantage of quickly placing the joint to be connected under the tail of the drill rod by providing the embedding hole 101, the ejection block 301, the arc plate 302, the pressing plate 303, the telescopic rod body 304 and the spring 305, so that the joint can accurately correspond to the connecting end of the tail of the drill rod, thereby solving the problem of errors caused by manually moving the joint to the bottom of the drill rod tail and the need to adjust the position multiple times to connect with the tail of the drill rod.

[0038] Specifically, two fixing blocks 2 are symmetrically fixed at the bottom of both sides of the tooling base 1, and mounting holes 201 are opened on the fixing blocks 2. Bolts pass through the mounting holes 201 and are tightened into the screw holes of the workbench to fix the tooling base 1 on the workbench.

[0039] Furthermore, a slide groove 102 is opened at one end of the top side of the tooling base 1, and the slide groove 102 is connected to the embedding hole 101; wherein, the ejection block 301 is completely embedded in the embedding hole 101 so that the top side of the ejection block 301 is aligned with the inner bottom wall of the slide groove 102.

[0040] The utility model has the advantage of pushing the joint into the installation position from one side of the tooling base 1 by setting the slide groove 102, so that the joint is conveniently placed at the installation position.

[0041] Furthermore, an annular groove 3011 is formed on the top side of the ejection block 301 , the outer side of the annular groove 3011 is aligned with the inner side of the arc plate 302 , and the circular end of the joint is inserted into the annular groove 3011 for positioning.

[0042] The utility model has the advantages of positioning the joint placed on the ejection block 301 by providing the annular groove 3011, and keeping the joint stable when the joint is moved up and connected with the tail of the drill pipe.

[0043] It is worth noting that the inner end of the pressing plate 303 is configured to be arc-shaped, and the inner end of the pressing plate 303 is aligned with the inner side of the arc-shaped plate 302, so that the pressing plate 303 will not hinder the joint.

[0044] Working principle: When using the device of the utility model, the bolt passes through the mounting hole 201 and is tightened into the screw hole of the workbench to fix the tooling base 1 on the workbench. When placing the joint, push the round end of the joint into the slide groove 102, and the outer wall of the round end of the joint contacts the two inner side walls of the slide groove 102. Press the pressing plate 303 downward, and the arc plate 302 pushes the ejection block 301 downward, the telescopic rod body 304 shortens, and the spring 305 is compressed until the bottom side of the ejection block 301 contacts the bottom side of the embedded hole 101. At this time, the top side of the ejection block 301 is aligned with the inner bottom wall of the slide groove 102. The joint is aligned, and is directly pushed to the top side of the ejection block 301, and stops when the joint contacts the arc plate 302. At this time, the round end of the joint corresponds to the annular groove 3011, and due to gravity, the round end of the joint is inserted into the annular groove 3011, and the force on the pressing plate 303 is slowly removed. Under the action of the spring 305, the pressing plate 303 moves up, the arc plate 302 drives the ejection block 301 to move up, and the joint moves up until the telescopic rod body 304 is extended to the maximum length and then stops. At this time, the connecting end of the joint corresponds to the tail end of the drill pipe, and the joint can be connected to the drill pipe.
