Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

A chiseling tool according to the present embodiment, as shown in fig. 1, includes a sliding hammer 1, a sliding rod 2, a toothed sleeve 3, and a fixing block 4, wherein the toothed sleeve 3 and the fixing block 4 are disposed at both ends of the sliding rod 2 at a certain distance, and the sliding hammer 1 is disposed between the toothed sleeve 3 and the fixing block 4, wherein the sliding hammer 1 can reciprocate on the sliding rod 2, and strike a striking surface 40 through a hammering surface 10 to generate an impact force F as a source of a detaching force. The slide hammer 1 is cylindrical and has a through hole 13 in the longitudinal direction. The sliding hammer 1 has a length L, the gear sleeve 3 and the fixed block 4 have a minimum distance L1, and the length L accounts for 40% of the distance L1. The through hole 13 of the slide hammer 1 has a diameter b in the range of 20-25 mm.

In fig. 1, the slide bar 2 has the shape of an elongated bar with a diameter a and a size in the range of 18-23 mm. The slide bar 2 is provided with a first handle 5 which is adjacently connected with the fixed block 4. The diameter c of the excircle of the fixed block 4 is 50-55 mm. The second handle 6 is arranged on the outer circular surface 11 of the sliding hammer 1 and forms a 90-degree layout with the central axis M of the sliding hammer 1.

As shown in fig. 2 to 4, the gear sleeve 3 is cylindrical, and the diameter d of the outer circle ranges from 65 mm to 100 mm. The outside has an inlet 31 communicating with the inside housing part 33. The inlet 31 of the gear sleeve 3 comprises a limiting part 32 which is in a circular hole shape and has a diameter f, and the size range is 24-55 mm. The sliding hammer 1, the sliding rod 2, the gear sleeve 3 and the fixing block 4 are all made of metal materials. The slide bar 2 penetrates through a through hole 34 with the diameter e of the gear sleeve 3, the slide bar 2 and the gear sleeve 3 are welded together in a gas shielded welding mode, then the slide hammer 1 penetrates through the slide bar 2 through an inner hole 13, then the through hole 41 of the fixed block 4 penetrates through the slide bar 2, the fixed block 4 and the gear sleeve 3 are welded and fixed together in a gas shielded welding mode after the distance between the fixed block 4 and the gear sleeve 3 is adjusted to L1. The handle sleeves 50 and 60 are respectively assembled on the first handle 5 and the second handle 6, the first handle 5 is usually held by the left hand, the second handle 6 is usually held by the right hand, the gear sleeve 3 is used for holding the second handle 6 by the inlet 31, the limiting part 32 is embedded into the concave ring 102 of the head part 101 of the chisel 100, the head part 101 of the chisel 100 is just placed in the accommodating part 33 of the gear sleeve 3, at this time, the first handle 5 is held by the left hand, the second handle 6 is held by the right hand, the side surface 12 (in figure 1) of the sliding hammer 1 and the bottom surface 30 (in figure 1) of the gear sleeve 3 are close to the rear direction of the fixing block 4, so that the hammering surface 10 heavily hits the hitting surface 40 to generate an impact force F, and the impact force F can be used as the force for disassembling the chisel 100, and the chisel 100 is pulled out of the fixing base to achieve the aim of disassembling the chisel 100.
