The end face of the flat pad 301 is provided with a first through hole 303. The end face of the cunning sleeve 302 is provided with a second through hole 304, and the diameters of the second through hole 304 and the first through hole 303 are consistent. Two ends of the flat pad 301 are each secured to a one inch sleeve 302 and the first 303 and second 302 through holes are aligned to form a pair of through holes 4 through the entire sleeve pad 3. The rivet hole 2 in the middle of the bar-shaped rod piece is provided with a counter bore 201, and in the connecting process, the inch sleeve 302 is inserted into the counter bore 201 to form tight fit. Therefore, the two curved arm parts 1 can be connected together, and the rivet hole 2 in the middle of the two curved arm parts 1 and the pair of through holes 4 on the sleeve gasket 3 form a rivet hole of an extended plate for subsequently installing rivets. Meanwhile, the two curved arm parts 1 are isolated by the flat gasket 301, so that the gap is filled, and the effect of stable correction is achieved. Therefore, in the installation process, the required curved arm pieces can be connected into a whole firstly, the rod pieces are placed into the security window at one time, rivets are additionally arranged on the rod pieces respectively, the installation is simpler and faster, the working efficiency is effectively improved, and the labor force is reduced.

Example two

Referring to fig. 1, 2 and 7, a crank arm with a sleeve pad includes a crank arm body 1, a sleeve pad 3 is connected to a middle portion of the crank arm body 1, and the sleeve pad 3 is preferably made of rubber. The sleeve pad 3 comprises a flat pad 301 and a cun sleeve 302 connected to the flat pad 301, wherein the cun sleeve 302 is connected to the crank arm body 1. The curved arm body 1 comprises a bar-shaped rod, and rivet holes 2 are formed in the middle and the end of the bar-shaped rod. The end face of the flat pad 301 is provided with a first through hole 303. A cun cover 302 is symmetrically arranged on the left side and the right side of the flat cushion 301, the cun cover 302 is of a plate-shaped structure, so that an コ -shaped sleeve cushion 3 is formed and is used for being clamped in the middle of a bar-shaped rod, and a rivet hole 2 in the middle of the bar-shaped rod is aligned with a first through hole 303 of the flat cushion 301 and is used for passing through a rivet. In this way, during installation, the sleeve pad 3 can be fixed to the crank arm member body 1 without being movable in the middle as in the conventional flat pad arrangement. Meanwhile, in the connecting process, the two crank arm pieces are separated by the sleeve gasket 3, so that the function of flattening the gasket and the function of correcting can be achieved, no deviation and friction exist in the using process, the stability is better, and the customer satisfaction is higher.
