The upper wall of the inner sleeve is provided with a sound-absorbing hole connected with the sound-absorbing chamber; It is inserted into the inner sleeve, and its lower end protrudes from the lower end of the inner sleeve, and a spring is set on the nut cover. The top end of the spring is placed in the positioning groove at the bottom end of the inner sleeve, and the bottom end of the spring is set on the nut. ;The lower sleeve is a hollow pipe body, the upper end of which is screwed to the lower end of the inner sleeve through an internal thread, a joint is provided on the lower end screw, two corresponding through slots are provided on the wall of the cylinder, a slider is provided inside the cylinder and It can slide up and down in it. The slider is provided with a through hole that runs through both sides and corresponds to the through slot on the cylinder wall. A spring is set between the slider and the inner sleeve; the sliding sleeve is a hollow tube , which is sleeved outside the lower sleeve and can slide up and down. There are two corresponding through holes on the tube wall corresponding to the through slots on the lower sleeve wall, and a bolt is used to pass through the through hole of the sliding sleeve and the lower sleeve. The barrel penetrates the slot hole and the slider penetrates the hole; the connecting rod is a hollow pipe body, its upper end is provided with an internal thread and is screwed with the joint at the lower end of the lower sleeve, and its lower end is screwed with several connecting rods to extend.

When in use, put the gunpowder and the fixing nails into the inner sleeve one by one, and hold the connecting rod to align the fixing nails with the floor where the suspension parts are to be fixed and hit them with force, so that the nail head hits the gunpowder and generates explosive force, thereby fixing the Nails are driven into the building floor. The housing remaining in the inner sleeve after the gunpowder explodes can be ejected out of the inner sleeve by pushing up the sliding sleeve and driving the push rod to move up through the slider.

The technical characteristics of the nail driver for the suspension part of the present utility model will be further described in detail below in conjunction with specific embodiments.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model suspension nail driver is mainly composed of an upper sleeve 10, an inner sleeve 20, a push rod 30, a lower sleeve 40, a sliding sleeve 50 and several connecting rods 60.

The upper sleeve 10 is a hollow tube, the upper end and the lower end of which are respectively provided with an upper end cover 11 and a lower end cover 12 and each is provided with a corresponding through hole 111, 121, and the upper edge of the through hole 111 of the upper end cover 11 forms a polygonal concave Groove 112. The inner sleeve 20 is a hollow tube, and the upper end of the upper sleeve 10 passes through the through hole 111 of the upper end cover 11 to be set in the upper sleeve 10, and the outer edge of the upper end forms a polygonal lip 21 and is placed in the through hole 111. In the polygonal groove 112 on the upper edge of the hole 111, the outer edge of the lower end is provided with an external thread 22 and passes through the through hole 121 to protrude from the lower end of the upper sleeve 10, and a muffler chamber is formed between the inner sleeve 20 and the upper sleeve 10 23. A number of sound-absorbing holes 24 connected with the sound-absorbing chamber 23 are also provided on the cylinder wall. The push rod 30 is a solid rod body, which is inserted into the inner sleeve 20 by the upper end of the inner sleeve 20, and its lower end protrudes from the lower end of the inner sleeve 20, and a spring 32 is sheathed by a nut 31, and the top end of the spring 32 pushes It is placed in the positioning groove 25 at the bottom of the inner sleeve 20 , and its lower end is set on the nut 31 . The lower sleeve 40 is a hollow pipe body, the inner edge of the upper end is provided with an internal thread 41 and is screwed to the lower end of the inner sleeve 20, and the lower end screw is provided with a joint 42, and two corresponding through slots are provided on the wall of the sleeve. 43, a slider 44 is provided inside the tube and can slide up and down in it.
