[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The support plate 1, first hinge seat 101, second hinge seat 102, movable part 103, first clamping claw 104, connecting part 105, second clamping claw 106, movable sleeve 107, adjusting rotating rod 2, mounting base plate 201, locking sleeve 3 and connecting screw 4 of this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods.

[0023] Example 1

[0024] Please see Figures 1-5 As shown, this utility model provides a technical solution: a tool clamping device for oil well downhole applications, comprising:

[0025] Support plate 1, with a first hinge seat 101 and a second hinge seat 102 fixedly connected to the left and right ends of the front of the support plate 1 respectively. A first clamping claw 104 and a second clamping claw 106 are movably connected to the inner sides of the first hinge seat 101 and the second hinge seat 102 respectively. A movable part 103 and a connecting part 105 are fixedly connected to one side of the first clamping claw 104 and the second clamping claw 106 respectively. A movable sleeve 107 is provided in the hinge groove at the right end of the connecting part 105.

[0026] The connecting screw 4 has a locking sleeve 3 threadedly connected to the outer surface of its front end, and one end of the locking sleeve 3 is provided with a handle.

[0027] The first clamping claw 104 and the second clamping claw 106 are arranged in a cross configuration. The rear side of the connecting screw 4 is fixedly connected to the outer surface of the connecting screw 4, and the front end of the outer surface of the connecting screw 4 is provided with a connecting thread. The connecting screw 4 passes through the inner side of the right end of the movable part 103, and the rear side of the locking sleeve 3 is in contact with the front of the right end of the movable part 103.

[0028] This technical solution: With the first clamping claw 104 and the second clamping claw 106, when it is necessary to clamp and fix a downhole tool, the tool is placed inside the second clamping claw 106. Then, the movable part 103 drives the first clamping claw 104 to rotate to the right. With the first clamping claw 104 and the second clamping claw 106 able to cooperate crosswise, the first clamping claw 104 can press against the surface of the downhole tool, achieving clamping of tools of different sizes. Next, with the cooperation of the movable sleeve 107, the connecting screw 4 is rotated, so that the threaded end of the connecting screw 4 enters the inner side of the right end of the movable part 103 (the right end of the movable part 103 has a U-shaped groove, and the right end of the front of the movable part 103 has a limiting protrusion, see details). Figure 1 and Figure 4Then, by driving the handle, the locking sleeve 3 is threadedly connected to the threaded end of the connecting screw 4. After the rear side of the locking sleeve 3 abuts against the right end of the front of the movable part 103, and with the assistance of the pulling of the movable part 103 and the connecting part 105 (it should be noted that the downhole tool has been positioned and clamped at this time), the first clamping claw 104 and the second clamping claw 106 can quickly lock the tool in position. When it is necessary to remove it, simply drive the locking sleeve 3 to rotate in the opposite direction at the threaded end of the connecting screw 4 by driving the handle, so that the connecting screw 4 is withdrawn from the inner side of the right end of the movable part 103. It is convenient to use, simple to operate, and can clamp tools of different sizes, with good applicability.

[0029] Example 2

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, an adjusting rod 2 is movably connected to the inner surface of the middle end of the support plate 1, and a mounting base plate 201 is fixedly connected to the rear side of the adjusting rod 2. Mounting holes are opened on the inner surfaces of both the support plate 1 and the mounting base plate 201, and the mounting holes on the inner surface of the support plate 1 correspond to the mounting holes on the inner surface of the mounting base plate 201.

[0031] This technical solution: The mounting holes on the inner surface of the mounting base plate 201 can fix the position of the device. With the assistance of the adjusting rod 2, the clamping angle of the device can be adjusted. After the bolt passes through the mounting hole on the inner surface of the support plate 1, the bolt can be tightened with the mounting hole on the inner surface of the mounting base plate 201 to fix the angle of the clamp.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
