The utility model relates to the field of fitness equipment, and discloses a counterweight-adjustable martial art fitness device which comprises a pipe body, threaded openings are formed in the two sides of the pipe body, mounting covers are mounted outside the threaded openings, a limiting plate is fixedly connected to the middle of the interior of the pipe body, and the limiting plate is fixedly connected with the pipe body. Four sets of counterweight water bottles are arranged on the two sides of the limiting plate in the pipe body respectively, sealing bottle caps are installed at bottle openings of the counterweight water bottles in a screwed mode, scale marks are arranged at the front ends of the counterweight water bottles, and a rubber anti-skid sleeve is installed on the outer portion of the pipe body. According to the martial art fitness device capable of adjusting the balance weight, the overall weight of the pipe body can be changed by adjusting the water amount in the balance weight water bottles, the gravity center position of the pipe body can be changed by changing the water amount of each balance weight water bottle, the scale marks on the balance weight water bottles can assist in precise balance weight adjustment, water in the balance weight water bottles can be recycled and is not wasted, and the balance weight can be adjusted conveniently. By means of the structure, the function of conveniently and flexibly adjusting the balance weight is achieved, and the problem that the balance weight is inconvenient to adjust is solved.

The utility model discloses a small incision operation for cataract is used incision drag hook, especially in the field of ophthalmic surgical instruments, including handle, hook handle and drag hook, handle, hook handle and drag hook between through a stainless steel strip bending and make, hook handle is located between handle and drag hook, and the parallel between the two steel strips of handle and hook handle is constituted to each other, the structure of drag hook is: the two steel strips of hook handle far away from handle one end are in turn to two sides right angle bending, again downward right angle bending, again right angle bending to handle direction and then arc connection closure, the width of handle is greater than hook handle, handle and hook handle between smooth transition, the two steel wires between handle are clamped and have first support strip, and handle outside fixed sleeve has the first sleeve pipe of stainless steel. The utility model effectively solved the effective solution to the problem that the existing ophthalmic surgical incision drag hook integrated stamping manufacturing process needs to consume a large amount of steel and produces a large amount of leftover material in the production process.

The application discloses a remote taking-out method of a reactor in-line collimator and an auxiliary tool for hoisting the collimator, and the method comprises the following steps: S1, a temporary channel with a preset length is built, and the outlet of the temporary channel is a bending piece; S2, the bending piece is partially inserted into at least one lifting lug of the collimator; S3, a guide core with rigidity and flexibility is connected with a lifting belt, and the end of the guide core away from the lifting belt is put into the inlet of the temporary channel, passes through the bending piece, and simultaneously or sequentially passes through the lifting lug of the collimator; S4, after the guide core passes through the two lifting lugs, the guide core is clamped by using a special clamp, and then the temporary channel is removed; S5, the guide core is driven by the special clamp to completely pass through the two lifting lugs, the lifting belt is driven to pass into the two lifting lugs, and then the guide core is disconnected with the lifting belt; and S6, the lifting belt is connected with a lifting machine, and the collimator is hoisted out by the lifting machine. The application can realize remote taking-out of the collimator in the reactor, and the operation is simple and reliable.
