[0023] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0024] First embodiment

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a starter motor with an external screw provided by the present invention; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part B is shown; Figure 4 for Figure 1 A starting motor with an external screw, comprising:

[0026] A housing 1, wherein both left and right ends of the housing 1 are provided with disassembly housings 2, and a threaded rod 3 is provided between the two disassembly housings 2;

[0027] A sliding cavity 5 is provided inside the threaded rod 3. A mounting assembly 6 is provided inside the sliding cavity 5. The mounting assembly 6 includes a threaded mounting rod 61. One end of the threaded mounting rod 61 is connected to a movable block 62. The surface of the threaded mounting rod 61 is threadedly connected to a second threaded sleeve 8.

[0028] The opening of the sliding cavity 5 facilitates the storage of the threaded mounting rod 61. The use of the limit block 63 and the limit groove 7 can prevent the threaded mounting rod 61 from falling off and being limited during movement. A circular stop block is connected to one end of the threaded rod 3 to facilitate the threaded rod 3 to pass through the two disassembly shells 2 and prevent it from falling off when fixed and installed through the first threaded sleeve 4.

[0029] The surface of the threaded rod 3 is threadedly connected with a first threaded sleeve 4 .

[0030] The sides of the movable block 62 are symmetrically connected to the limiting blocks 63 .

[0031] A limiting groove 7 matched with the limiting block 63 is formed on the surface of the threaded rod 3 at a side opposite to the sliding cavity 5 .

[0032] A fixing bolt 9 is provided between the threaded rod 3 and the threaded mounting rod 61 .

[0033] A plurality of fixing holes matched with the fixing bolts 9 are provided between the threaded rod 3 and the threaded mounting rod 61 .

[0034] The working principle of a starter motor with an external screw provided by the present invention is as follows:

[0035] During use, when installing the entire device between the equipment, first move the threaded mounting rod 61 in the sliding cavity 5 inside the two threaded rods 3 outward. When the threaded mounting rod 61 moves outward, it drives the movable block 62 to move inside the sliding cavity 5. When the movable block 62 moves, it drives the limit block 63 to move inside the limit groove 7 opened on the surface of the threaded rod 3. When the threaded mounting rod 61 moves to a suitable length, use the fixing bolt 9 to pass through the threaded rod 3 and connect it to the threaded mounting rod 61, and then the threaded mounting rod 61 can be installed on the equipment. Finally, use the second threaded sleeve 8 to threadably connect it to the threaded mounting rod 61.

[0036] Compared with the related art, the starter motor with an external screw provided by the present invention has the following beneficial effects:

[0037] The present invention provides a starting motor with an external screw, in which a threaded mounting rod 61 with a movable block 62 and a second threaded sleeve 8 are arranged inside a threaded rod 3 with a sliding cavity 4 for cooperative operation. After being installed between two disassembly shells 2 and a shell body 1, the threaded mounting rod 61 inside the threaded rod 3 can be used for auxiliary installation when the entire device is installed between equipment, thereby improving the convenience of use.

[0038] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
