[0008] The lower part of the outer tube is equipped with necked structure outside.

[0009] The size of the boss is greater than the size of the push rod mounting hole.

[0010] The material of the outer tube, handle and spring is selected from stainless steel, and the material of the push rod is selected from 45# steel.

[0011] Compared with prior art, the utility model optimizes manual operation procedure, improves magnet assembly production efficiency, and can be suitable for different size magnets. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is the structure schematic diagram of the utility model.

[0013] Figure 2 It is the structure schematic diagram of the utility model when using. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1 As shown, the outer tube 1 is provided with push rod mounting holes and magnet assembly hole groups from top to bottom. The push rod mounting hole is provided with push rod 2. The upper end of push rod 2 is connected to handle 4 through elastic pin 3. The lower end of push rod 2 is provided with boss 5. The magnet assembly hole group includes several magnet assembly holes 6 with different diameters. The diameter of magnet assembly holes 6 increases from top to bottom.

[0016] A spring mounting hole 7 is provided on the outside of the push rod mounting hole, and a spring 8 is installed inside the spring mounting hole 7. The spring 8 is sleeved on the outside of the push rod 2. The spring 8 in the compressed state has a certain preload force, which clamps the push rod 2. After the magnet is assembled, the spring 8 returns to its original position.

[0017] The lower part of the outer tube 1 is provided with a concave stop 9, which cooperates with the convex stop of the part to be installed 12, so as to quickly and effectively position the part to be installed 12.

[0018] The outer tube 1 has a constriction structure 10 on the lower outer side to prevent interference between the outer tube 1 and the part 12 to be installed.

[0019] The size of the boss 5 is larger than the size of the push rod mounting hole to prevent the push rod 2 from coming out.

[0020] The outer tube 1, handle 4, and spring 8 are made of stainless steel. The push rod 2 is made of 45# steel to attract the magnet and store it inside the outer tube 1.

[0021] The handle 4 and the push rod 2 are connected by a spring pin 3, which facilitates disassembly, assembly and maintenance.

[0022] When using this utility model, such as Figure 2 As shown, pressing the handle 4 moves the push rod 2 into the magnet mounting hole 6, drawing the magnet 11 into the hole. Then, the concave stop 9 at the outer tube 1 aligns with the convex stop of the part 12 to be installed. The concave stop structure at the outer tube 1 matches the outer diameter of the part 12, achieving quick docking and positioning. Next, pressing the handle 4 further installs the magnet 11 into the part 12. The magnet 11's dimensions are interference-fitted with the part 12, securing it in place. Releasing the handle causes the push rod 2 to reset under the action of the spring 8, allowing the remaining magnet 11 to retract into the outer tube 1 for quick installation of the next part, until all magnets are installed.

[0023] In this utility model, the magnet assembly hole group includes several magnet assembly holes 6 with different diameters, which facilitates the assembly of magnets 11 of different sizes according to the on-site construction conditions.
