Detailed Description

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

A pneumatic tool adapting detacher of the embodiment is shown in figure 2 and comprises a plug pin part 20, a stopping part 10, a supporting rod 30 and a working head 40, wherein the working head 40 is formed by a section of a bent cylinder and has a diameter a in the size range of 10-13mm, and the working head 40 has a central axis L1 which has a radius R in the size range of 70-80 mm.

In fig. 1 and 2, the support rod 30 of the detacher 1 is connected to the working head 40, the cross section of the support rod 30 is formed by a regular polygon, and is generally arranged in a regular hexagon, and the size d of the opposite side ranges from 15mm to 18 mm. The stop part 10 of the detacher 1 comprises a first stop surface 10.1 and a second stop surface 10.2 which are recessed towards the direction of the central axis L on the support rod 30 to form a revolution body surface. The first 10.1 and the second 10.2 stop surfaces of the stop 10 form a circular cross section with a diameter b in the range of 12-13 mm. The stop part 10 is located at the end of the detacher 1 at a minimum distance D from the latch part 20 of the detacher 1 and has a size in the range of 40-45 mm.

As shown in fig. 1 to 3, a latch part 20 is formed at the transition of the stopper part 10 to the tail part, and has a regular polygonal section, which is generally configured as a regular hexagon, and has a side-to-side dimension c ranging from 9 to 10 mm. Plug pin portion 20 has a length D1 and a size in the range of 30-32 mm. The working head 40 of the detacher 1 has a working surface 41, which is constituted by a cross section of the working head 40. The latch portion 20 of the detacher 1 has a force-bearing surface 21 which receives a force from the punch striking surface 130 during operation to produce a displacing function.

As shown in fig. 3 and 4, the plug part 20 of the detacher 1 penetrates through the inlet 165 of the stopper 16 and enters the accommodating cavity 163 of the cavity 160, meanwhile, the plug part 20 penetrates through the guide part 141 of the barrel 14, the guide part 141 is configured to be an internal hexagonal hole shape and is adapted to the shape and size of the plug part 20, and then the internal thread 161 of the stopper 16 is screwed onto the external thread 140 of the barrel 14, so that the assembling steps of the barrel 14, the stopper 16 and the detacher 1 are completed.

In fig. 3 and 4, the cylinder 14 is connected to the body 11 by the stabilizer ring 15, and the punch 13 is mounted in the cylinder wall 142 of the cylinder 14 to be engaged with the ring surface 131 of the punch 13. The limiting block 16 comprises a first limiting surface 16.1 and a second limiting surface 16.2 which are correspondingly matched with the first stopping surface 10.1 and the second stopping surface 10.2 of the detacher 1 respectively. During the use of the pneumatic tool, the air inlet 110 is connected to a required air supply pipe, compressed air enters the inner cavity of the body 11, the compressed air pushes the air guide block 12 to move towards the direction of the limit block 16 along the direction of the central axis L, the stop surface 120 of the air guide block 12 strikes the stop surface 132 of the punch 13 in the cylinder 14, so that the punch 13 also moves towards the direction of the limit block 16, the striking surface 130 of the punch 13 strikes the force-bearing surface 21 of the plug part 20 of the detacher 1, thereby causing the detacher 1 to rapidly reciprocate between the first limit surface 16.1 and the second limit surface 16.2 of the limit block 16, the force F applied by the punch striking surface 130 is transmitted from the force-bearing surface 21 to the central axis L1 along the central axis L, and is finally released to the workpiece 18 to be detached through the working surface 41, and the working process of detaching the chisel 18 is completed.
