On both sides of the mounting seat 10 extends to the inside of the mounting chamber 9, the device housing 1 The inner portion is opened, and the inner cavity of the drive chamber 8 can be rotatably disposed, and the front end surface of the rotary disk 12 is fixedly mounted, and the front end of the rotation shaft can be rotatably extended to the front side of 01.

[0022] The rotating pan 12 can be rotated by the worker to rotate the rotating shaft.

[0023] Both sides of the surface of the rotary disk 12 can be rotatably provided with both sides of the drive chamber 8, and the slider 15 is slidably provided, and the connecting rod 13 rotates from one end of the rotary disk 12 to the slider 15. On one side of the slider 15, a fixed bar 14 is mounted laterally, and one end of the fixing rod 14 is slidably extended to the interior of the connecting block.

[0024] In the present embodiment, by providing a connecting block on the upper surface of the mount 10, when the device housing 1 is fixedly mounted, the device housing 1 is placed on the upper surface of the mount 10, and then the connecting block is inserted into the lumen of the mounting chamber 9. However, the rotary disc 12 is then rotated such that the rotary disc 12 drives the connecting rod 13 to move, and when the two connecting rods 13 are moved to both sides of the rotary disk 12, the connecting rod 13 can push the slider 15 to move, so that the slider 15 Volume The fixing rod 14 is fixed to the inside of the connecting block.

[0025] Further, the rear end surface on both sides of the outer casing 1 is opened, and the inner chamber of the two support chambers 4 is laterally threaded, and the active threaded rod 5 is connected to the end surface of the device housing 1. 5 A suitable threaded hole, the threaded hole is provided with several, and the surface of the movable threaded rod 5 is rotatably provided with the first support rod 6.

[0026] In the present embodiment, by providing a plurality of threaded holes, the first support rod 6 is deployed after the device housing 1 is fixed, and then the active thread rod 5 is inserted into the first support rod 6 through the threaded hole. The rod 6 is fixed.

[0027] Further, the inside of the first support rod 6 is slidably provided with a second support rod 7, and the internal detachable portion of the second support rod 7 is detachably disposed, and the rear end surface of the first support rod 6 is opened, and the positioning hole, activity The rear end of the threaded rod 5 can be rotatably extended to the rear end surface of the device housing 1.

[0028] In the present embodiment, when the length of the first support rod 6 is not sufficient, the positioning rod inside the first support rod 6 can be extracted, and the second support rod 7 is unfolded, and the positioning rod is inserted into the second position. When the support rod 7 is fixed, the first support rod 6 or the second support rod 7 is fixed to the ground while the second support rod 7 is fixed, and the device housing 1 can be prevented from inclined.

[0029] Further, the front end surface of the device housing 1 is opened with a sliding chamber 16 in communication with the working chamber 2, and the inside of the slide chamber 16 is slidably disposed, and the front end surface of the outer rear side of the outer casing 1 is opened. 17 The inner portion of the activity chamber 17 can be rotatably provided with a fixed threaded rod 11, and the top thread of the fixed threaded rod 11 is connected to the mobile seat 24.
