Referring to fig. 1 to 3, a quick screw installation tool includes a drill bit 1 and a hammering sleeve 2, the drill bit 1 can be sleeved on the hammering sleeve 2, the drill bit 1 is a cylinder, but not limited to a cylinder, and may also be a square or hexagonal drill bit 1 with a hammering end face 6, specifically:

the drill bit 1 comprises an electric hammer connecting handle 3, a connecting part 4 and a drill body 5, wherein a hammering end face 6 is arranged at one end of the electric hammer connecting handle 3, and the connecting part 4 is arranged between the hammering end face 6 and the drill body 5; the electric hammer connecting handle 3 is used for connecting an electric hammer, and the electric hammer connecting handle 3 can be one of a round four-pit handle, a square handle or a hexagonal handle and can also be in other shapes. Preferably, the hammering end face 6 has a diameter larger than the diameter of the drill body 5. The hammering end face 6 conducts the hammering force of the electric hammer to the hammering sleeve 2 to hammer the core part of the expansion nail 16 forwards to expand the expansion nail 16 so as to rivet and fix the expansion nail in the hole. Wherein the connecting portion 4 is intended to be connected with the hammering sleeve 2. Connecting portion 4 of drill bit 1 is equipped with draw-in groove 7, draw-in groove 7 is the arc recess form, and when hammering sleeve 8 cup jointed on drill bit 1, steel ball 12 and shell fragment 13 that are equipped with on the hammering sleeve 8 can block into the circular arc recess in and make firmly attaching to of hammering sleeve pipe 2 can not drop on drill bit 1.

Hammering sleeve pipe 2 includes hammering sleeve 8, hammering stick 9, be equipped with spring portion 10 between hammering sleeve 8 and the hammering stick 9, be equipped with on the hammering sleeve 8 and cup joint portion 11, 2 inside cavitys of hammering sleeve pipe, the drill body 5 can stretch into 2 inside hammering sleeve pipes, and the mutual gomphosis of the portion 11 of cup jointing of connecting portion 4 and hammering sleeve 8 of drill bit 1. Preferably, the sleeve joint part 11 of the hammering sleeve 2 is provided with a steel ball 12 and a spring sheet 13. The sleeve joint part 11 is provided with a groove for installing an elastic sheet 13 and a steel ball 12, when the hammering sleeve 2 is sleeved on the drill bit 1, the steel ball 12 can be clamped into the clamping groove 7 on the drill bit 1 to attach the hammering sleeve 2 on the drill bit 1 without falling off.

Furthermore, a reducing part 14 is arranged between the connecting part 4 of the drill bit 1 and the drill body 5, and the diameter of the reducing part 14 is smaller than that of the drill body 5. Preferably, said reduced diameter portion 14 is not threaded and the drill body 5 is threaded. The purpose of the reducing part 14 is to improve the problem that a section of drill body 5 without threads is left because the threads cannot be milled to the bottom in the existing drill bit 1 processing technology, when the drilling depth reaches the drill body 5 without threads, the drill bit 1 is clamped because dust cannot be discharged smoothly, and the electric hammer throws hands to cause injury to human bodies. The drill body 5 with the reduced diameter portion 14 can lead dust into the reduced diameter portion 14, thereby solving the problem that the drill bit 1 can reach deeper drilling depth without blocking hands of the drill bit 1.

Furthermore, a limiting front sleeve 15 is arranged at one end, far away from the spring part 10, of the hammering rod 9, and a limiting hole is formed in the limiting front sleeve 15. The front end of the hammering rod 9 is provided with a front limit sleeve 15, and a spring part 10 at the rear end of the front limit sleeve 15 pushes and presses the front limit sleeve 15 forwards. The purpose is to limit the protruding nail head of the expansion nail 16 in the hammering range of the hammering rod 9 (the limiting hole of the limiting front sleeve 15 = hammering range), and not to make the nail head of the expansion nail 16 separate from the hammering range of the hammering rod 9 due to the jumping during hammering.

The use method of the expansion screw quick installation tool comprises the following steps:

1. drilling a hole in the cement wall by using a drill bit 1;

2. inserting the hammering sleeve 2 on the drill bit 1, and automatically clamping the steel balls 12 of the hammering sleeve 2 into the clamping groove 7 of the drill bit 1;

3. inserting an expansion nail 16 into an object to be installed and a cement drill hole, and sleeving a limiting front sleeve 15 of the hammering sleeve 2 on a protruding nail head of the expansion nail 16;

4. the electric hammer is driven to hammer the protruding nail of the expansion nail 16 into the cement wall, and the front limiting sleeve 15 can limit the head of the expansion nail 16 in the sleeve to prevent the expansion nail from jumping out of the hammering range of the hammer rod 9 during hammering. The limiting sleeve is gradually retracted along with the gradual entering of the expansion nail into the wall surface, and the forward elasticity of the spring enables the convex nail head to be kept in the limiting front sleeve 15 until the expansion nail 16 is hammered.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
