The inner driver cover 30 has a convex portion 31 and can abut against the outer periphery of the body 1 on the outer surface of the body. The bolt hole 113 is provided with a plurality of positioning weights=2, wherein the clamping card bolt 32 can be bolted into the bolt hole ία, and the screw hole 112 of the convex portion & two flange 111 is provided with a plurality of screw holes 33 for screwing the screw member 34 Tan fixed this, 10 and cover 3 〇 'cap 3 〇 on the inner ring with a number of accommodating celestial slots 35 open to the outside of the cover 3 。. Wherein the piston 2〇 is limited to seven: 24, the outer edge is larger than the inner diameter of the cover 3〇, so that the piston 20 can only extend 4^ to the aged 24 card to reach the 3Q, and the limit (4) can only be ^' and prevent The piston 2 () is pushed up by the high-pressure air and is pulled out. The second expansion rod 4G is made of a die-casting, and the expansion rod 4 () has a weft handle & and a free end 43, wherein the head 21 of the piston 20 can The jacking rod 40 is outwardly expanded, and each of the expanding rods 40 can be connected to the pivoting end 41 of each of the expanding rods 4G by the buckle 42 so as to be connected with the expanding rod 4Q, and the buckle is connected to the expanding rod 4〇 In the same manner, the free end (4) of the expansion rod 4Q is extended from the outer side of the receiving recess 35 to the outer side of the retaining ring 42 to the outer side of the cover 3, so that the expansion rod 4 can be stably pivotally coupled. The cover is 3 〇, and the expansion 40 can pivot in the space of the valley slot 35. When the piston is in the first position, the expansion rod 40 1 is in a contracted state, and when the piston 20 is in the second position, the expansion cup 4G is in an expanded state (as shown in the figure), and in the first position, the control valve 14 is in a closed position. The intake port 122_, the piston 2 is located at: the bottom of the body; in the second position, the control valve 14 is in the open position to open the inlet 122, and the high-injection air enters the push-up expansion rod 4 to expand outward. The cover 30 is also sleeved with an elastic shrink sleeve 5〇, and the shrink sleeve 5 is sleeved on the outer periphery of each of the expansion rods 4〇, so that the elastic force of the shrink sleeve 5〇 in the normal state makes the expansion rods 40 Converging inward, convenient for the dust jacket 6 〇 set. Referring to FIG. 6 to FIG. 7 , it is a cross-sectional view taken along line 6_6 and the section line of FIG. 5 of the present invention, showing a structure in which the body 10 and the cover 30 are positioned and fixed to each other, and the cover 3 is assembled first. The positioning card is positioned in alignment with the bolt hole 113 of the body 10, and the screw member 34 and the screw holes 112, 33 of the body 1〇3 are screwed and fixed. The month >", Fig. 8 is a state diagram of the use of the present invention. When the control valve 14 is pressed, the air inlet 122 of the body is in an open state, so that the piston 2 is forced to push the respective expansion rods 40 toward each other. The outer expansion portion, and the stopper portion 24 of the live plug 20 abuts against the cover 30 to prevent the piston 2 from coming out, wherein the abutting member 23 of the piston 20 contacts and rubs the expansion rods 40, and the abutting member 23 can prevent expansion. The rod 4〇 is in direct contact with the miscellaneous piston 2Q, and the piston 2Q is prevented from affecting the degree of expansion of the expansion rod 40 due to long-term wear depression. Please refer to FIG. 9 and FIG. 10 , which are the action-like cancer diagrams of the automobile dust-proof detachable tool of the present invention. When the piston 2 is in the first position, the dust jacket 6 先 is first inserted into the periphery of the expansion rod 40 in the contracted state, and then The high-pressure air is connected, and the high-pressure air is pressed to press the high-pressure air to push the piston 2〇 (shown in FIG. 8) to the second position, and the expansion rod 4 is expanded, so that the expansion rod expands outward. Expanding, and then moving the disassembly tool of the present invention to install the dust jacket 60 or remove the dust jacket 6〇. As described above, the present invention can be summarized as follows: 1. The "automobile dust cover disassembly tool" of the present invention, wherein the buckle can be conveniently and quickly ||^ each expansion rod is convenient to assemble and does not need to be The tool assists the solid expansion rod, and the _g_ has a good ring pull force, which makes the expansion rods force the average, which is a very progressive design. 2. The "automobile dust cover disassembly tool" of the present invention, wherein the piston is recessed on the surface of the installation, and the county can prevent the expansion of the wear piston and prevent the expansion of the piston convex portion from affecting the expansion degree of the expansion. The above is only the preferred embodiment of the present invention. When it is not possible to use this (4) actual description, the change or equivalent of the record, or the change of the patent according to this (4) Modifications should still fall within the scope of the invention patent.
