[0016] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0017] Please refer to Figures 1 to 3, the present utility model provides a claw - type expansion tool, which includes a plurality of claw bodies 1, a fixed block 2, a cylinder 3 and a sleeve 4. A connecting block 5 is arranged on the claw body 1. The output end of the cylinder 3 is provided with a telescopic rod 6. A plurality of the claw bodies 1 are respectively arranged at one end of the sleeve 4. The connecting block 5 is arranged outside the fixed block 2. The cylinder 3 is fixedly connected to the sleeve 4 and is located at the other end of the sleeve 4. And the telescopic rod 6 is fixedly connected to the fixed block 2 and is located at one end of the fixed block 2.

[0018] In this embodiment, through the cooperation of the cylinder 3 and the telescopic rod 6, the fixed block 2 and the connecting block 5 expand a plurality of the claw bodies 1 under the action of the hinge, thus saving time and effort in expanding the rubber sleeve and also improving the connection efficiency between the rubber sleeve and the receiving instrument.

[0019] Furthermore, a through - hole 7 is formed on the claw body 1, and the connecting block 5 is also hinged to the claw body 1 through a cylindrical pin 8 and is located within the through - hole 7.

[0020] Furthermore, the telescopic rod 6 is slidably connected to the sleeve 4 and is located within the sleeve 4 and also penetrates through both ends of the sleeve 4.

[0021] In this embodiment, by passing the telescopic rod 6 through the sleeve 4, it is convenient to improve the stability when a plurality of the claw bodies 1 expand.

[0022] Furthermore, one end of the sleeve 4 is provided with multiple groups of first support members. The first support member includes two first support pieces 9. A plurality of the claw bodies 1 are respectively hinged to the corresponding first support pieces 9 through cylindrical pins 8 and are located between the two first support pieces 9.

[0023] In this embodiment, through the arrangement of the first support piece 9, it is convenient to hinge the claw body 1 at one end of the sleeve 4, so that it can perform an expansion action.

[0024] Furthermore, multiple groups of second support members are arranged outside the fixed block 2. The second support member includes two second support pieces 10. The connecting block 5 is hinged to the corresponding second support pieces 10 through cylindrical pins 8 and is located between the two second support pieces 10.

[0025] In this embodiment, through the arrangement of the second support piece 10, it is convenient to hinge the connecting block 5 outside the fixed block 2, so that the fixed block 2 can expand and close the claw body 1 under the action of the telescopic rod 6 and the cylinder 3.

[0026] In this embodiment, a rubber sleeve is sleeved on the plurality of claw bodies 1, and then the air cylinder 3 is started to drive the telescopic rod 6 to perform a reciprocating linear motion. Under the action of the hinge connection between the connecting block 5 and the fixed block 2, the claw body 1 performs an angular change motion to complete the opening action, thereby expanding the diameter of the rubber sleeve. At the same time, the plurality of expanded claw bodies 1 are sleeved on the outside of the receiving instrument. Finally, the air cylinder 3 is retracted, and the plurality of claw bodies 1 slowly close. Then, the rubber sleeve is manually moved from the plurality of claw bodies 1 to the outside of the receiving instrument. This design has a neat overall appearance and no burrs or flash.

[0027] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
